Clinical Review

Prostate cancer is the most frequently diagnosed cancer in men and the third leading cause of cancer death in men worldwide.¹ An estimated 174,650 new cases are diagnosed each year in the United States; 31,620 American men die annually from the disease.² Although prostate cancer can be a serious disease, many men do not die from it. In fact, 2.9 million men who were diagnosed with prostate cancer at some point are alive today.³

Risk factors. Prostate cancer develops mainly in men ages ≥ 65 years and rarely occurs before age 40. In addition to age, family history and African American ethnicity are the major nonmodifiable risk factors for prostate cancer.⁴ From the 1970s to the most recent statistical analysis of the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) program, African American men have continued to have significantly higher incidence of, and mortality rates from, prostate cancer than their European American counterparts. African American men are also more likely than men of European ancestry to have aggressive prostate cancers.⁵ Other risk factors include geographic location (higher risk in Northern Europe, North America, and Australia; lower risk in Asia, Africa, and South and Central America), mutations in the BRCA2 gene, and hereditary non-polyposis colon cancer syndrome.⁴

Prostate-specific antigen (PSA) was first used as a screening tool for prostate cancer in 1991.⁶ Prostate cancer incidence, especially organ-confined disease, has dramatically increased since then.⁷ PSA testing has a low sensitivity and specificity for the detection of prostate cancer, and there is no clear threshold at which biopsy can or should be offered. The most commonly used cutoff value of 4 ng/mL has a false-positive rate of about 70%.⁸

Benign prostatic conditions such as hypertrophy and infection can elevate PSA levels. In addition, the PSA test does not distinguish between aggressive and slow-growing cancers, and about 15% of patients with prostate cancer have a normal PSA level.⁹

A word about the digital rectal exam. While PSA testing has been the mainstay of prostate cancer screening, a few studies have included digital rectal exam (DRE) in their protocols. Data from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial showed that DRE captured an additional 2% of men with prostate cancer in the setting of a normal PSA test result.¹⁰ In the Rotterdam arm of the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial, the overall detection rate for prostate cancer was found to be better when DRE was combined with PSA and prostate biopsy than when DRE was used alone (4.5% vs 2.5%).¹¹ Nevertheless, generally speaking, DRE can be omitted in the era of PSA screening.

Screening guidelines vary

Recommendations for prostate cancer screening vary by organization and are summarized in TABLE 1.^9,12-14 In 2012, the US Preventive Services Task Force (USPSTF) recommended against PSA-based screening for prostate cancer (Category D).¹⁵ In 2018, ­USPSTF provided an update with a new recommendation that clinicians inform men ages 55 to 69 years about the potential benefits and harms of PSA-based screening (Category C).¹⁴ The USPSTF continues to recommend against PSA-based screening for men ages ≥ 70 years (Category D).¹⁴

Does PSA-based screening improve patient-centered outcomes?

Several randomized controlled trials (RCTs) such as the Quebec Prospective Randomized Controlled Trial,¹⁶ the Norrköping Sweden Study,¹⁷ ERSPC,¹¹ and PLCO¹⁰ have been conducted to assess the benefits of PSA testing. PLCO and ERSPC have contributed significantly to our understanding of prostate cancer screening even though their 13-year follow-up results are conflicting (TABLE 2).^10,11,18

Continue to: In the ERSPC 13-year follow-up publication...

In the ERSPC 13-year follow-up publication, the authors concluded that a substantial reduction in prostate cancer mortality is attributable to testing with PSA.¹⁸ Despite limitations in the study design (eg, France entered after 2 years, screening intervals varied between 2 and 4 years, biopsy indications varied, and screening was discontinued at different times), PSA screening detected more prostate cancer than was detected in the control arm (10.2% vs 6.8%).

In the initial 11 years of follow-up, the study group experienced a 21% reduction in prostate cancer mortality, even though the absolute decrease ranged from only 0.6% (545 per 89,352) to 0.5% (355 per 72,891). The updated absolute risk reduction of death from prostate cancer at 13 years of follow-up showed a larger benefit: 0.11 per 1000 person-years or 1.28 per 1000 men randomized, which is equivalent to 1 prostate cancer death averted per 781 (95% confidence interval [CI], 490-1929) men invited for screening, or 1 per 27 (17-66) additional prostate cancers detected.

The PLCO trial did not show any significant difference in prostate cancer detection (11.1% screened vs 9.9% control), and there was no improvement in prostate cancer mortality (3.7 vs 3.4 death per 10,000 person-years).¹⁰ However, the PLCO trial suffered from issues of contamination, which may have influenced the overall results. About 52% of men in the control (usual care) group received a PSA test at some point during the study. And more than two-thirds of the men who had a prostate biopsy because of a positive PSA test did not have prostate cancer.

Community standards for the PSA threshold for biopsy were applied in various centers (> 4 ng/ml in general) in PLCO, whereas in ­ERSPC, a cut-off PSA value ≥ 3 ng/mL was used for biopsy. Because of the lower PSA threshold, ERSPC may have identified cancers that would have had good outcomes without any intervention.

The harms of PSA screening

While it is unclear whether PSA screening results in any improvement in patient-centered outcomes, it does lead to downstream intervention due to overdiagnosis, which precipitates unnecessary anxiety, biopsies, and overtreatment (eg, excess radiation, overuse of androgen deprivation therapy).¹⁹ Biopsies carry the risk of hematuria (22.6%), hematospermia (50.4%), and urinary tract infection.²⁰ Data from SEER-Medicare showed that prostate biopsy was associated with a 2.65-fold increased risk of hospitalization within 30 days of the procedure compared to a control population.²¹

Continue to: Overdiagnosis leads to overtreatment...

Overdiagnosis leads to overtreatment of low-risk prostate cancer. Both traditional treatment options for prostate cancer—radical prostatectomy and radiotherapy—are associated with urinary incontinence, erectile dysfunction, and issues with bowel function.^22,23

The Prostate Cancer Intervention vs Observation Trial (PIVOT),²⁴ the Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4),²⁵ and the Prostate Testing for Cancer and Treatment (ProtecT) trial,^22,23 are the major RCTs that looked at the outcomes of treatment modalities for localized prostate cancer in the modern era of PSA testing.

PIVOT compared passive observation with radical prostatectomy.²⁴ After 20 years of follow-up on 731 patients, the researchers concluded that radical prostatectomy did not reduce all-cause or prostate cancer–related mortality (TABLE 3).²⁴

SPCG-4 showed survival benefits for men who underwent radical prostatectomy compared with men in a watchful waiting group, but only 5% of the study cohort had cancer detected by PSA screening (TABLE 4).²⁵ The rest had either palpable tumors or symptoms of a tumor.

ProtecT, which followed patients with localized prostate cancer for more than 10 years,compared the outcomes and adverse effects of active surveillance, radical prostatectomy, and radiotherapy.²³ Prostate cancer–specific mortality was low irrespective of the treatment,²³ and there was no significant difference in all-cause mortality or prostate cancer–specific mortality between the 3 treatment groups.²³ The active surveillance group had considerably fewer adverse events.^22,23 The incidence rates of erectile dysfunction and urinary incontinence at the 1- and 6-year follow-up marks are outlined in TABLE 5.²²

Continue to: The purpose of active monitoring...

The purpose of active monitoring is to minimize overtreatment by avoiding immediate radical intervention. Radical treatments with curative intent can be undertaken at any point while patients are being actively monitored. It is important to note that the active monitoring that took place in ProtecT²³ was very different from the passive surveillance of PIVOT²⁴ and SPCG-4.²⁵ In ProtecT, once an elevated serum PSA level was noted, PSA levels were monitored every 3 months in the first year and every 6 to 12 months thereafter.²³ Triggers to reassess patients and consider a change in clinical management were based largely on changes in PSA levels. Participants with an increase of at least 50% in PSA level during the previous 12 months were offered either continued monitoring or treatment after further testing.

Making individualized decisions about prostate cancer screening

Traditionally, the goal of cancer screening has been to maximize the number of people screened. Generally, the information provided to patients about cancer screening emphasizes the benefits and minimizes the harms. Recently, however, there has been a shift in communication about cancer screening with the emphasis now being placed on informed decision-making and encouraging patients to make individual decisions about screening participation.²⁶

Although current guidelines regarding PSA screening differ by organization, generally speaking, PSA screening should be offered only to men with a life expectancy > 10 years.

The treatment option of active surveillance, with its lower incidence of adverse outcomes, is an important reason for patients to make individualized decisions about prostate cancer screening.

Another reason relates to 5-alpha-­reductase inhibitors. Although their role in the management of prostate cancer is currently not well defined, a reduction of almost 25% in the risk of prostate cancer and improvement in the performance of PSA has been reported.²⁷

The PSA test has low sensitivity and specificity and lacks a clear cut-off value that warrants prostate biopsy.

And yet another reason is that there are alternate strategies to manage the majority of patients who have been diagnosed with low-risk disease through transrectal ultrasound biopsy. The ERSPC study mentions multiparametric magnetic resonance imaging combined with targeted biopsy to identify high-grade disease.^28,29 Genetic and epigenetic assays of the biopsied tissue can help grade disease based on aggressiveness.³⁰ Transperineal mapping biopsy using a mapping software program can identify specific disease sites within the prostate gland, so that patients can be offered the option of targeted therapy.³⁰

Applying shared decision-making to prostate cancer screening

Balancing errors of omission with errors of commission is challenging. Shared decision-making (SDM) is an approach whereby clinicians and patients share the best available evidence when faced with the task of medical decision-making and in which patients are supported while they consider their options and achieve their preferences.³¹ SDM is well supported by evidence from a number of RCTs and results in increased knowledge, involvement, and confidence on the part of patients.³² An individualized approach using the schematic diagram (FIGURE 1^3,18) may be helpful.

Barriers to SDM success. Many factors can interfere with the success of SDM including limited or poor communication; lack of time during busy office visits; and patients’ cultural, informational, and/or emotional needs. To improve patient-centered communication, we can: (1) make information understandable and available to patients and families; (2) prioritize training in communication; (3) use decision aid tools to facilitate communication; and (4) work to improve the payment model to incentivize patient-centered communication. Tools that facilitate SDM include videotapes, patient group discussions, brief scripts read to patients, and informational pamphlets. One such tool is the American Society for Clinical Oncology’s decision aid tool for PSA testing.³³

Limited knowledge among patients. Decisions regarding treatment among men diagnosed with localized prostate cancer can be difficult because there are several treatment options with similar prognoses, but there are differences in adverse effects. One population-based cohort study of men with newly diagnosed localized prostate cancer found that most men had significant knowledge deficits regarding the survival benefits of the 2 major treatment options—surgery and radiation.³⁴ In a large population-based study, 38% of men with localized prostate cancer reported receiving help from their primary care providers in the decision-making process for treatment.³⁵

Learning to employ SDM. Elwyn et al proposed a 3-step model to incorporate SDM into clinical practice.³¹ They described key steps that include: choice talk (making sure patients are informed about the reasonable options), option talk (providing more detailed information about the options), and decision talk (supporting the work of patients considering their preferences and deciding what is best). Properly employing these methods requires training using simulations.³¹

The bottom line

Although current guidelines regarding PSA screening differ by organization, generally speaking PSA screening should be offered only to men with a life expectancy > 10 years. The PSA test has low sensitivity and specificity and lacks a clear cut-off value that warrants prostate biopsy. Men who choose to have PSA testing increase their chances of detecting prostate cancer, but most prostate cancers are slow growing and do not cause death. The decision to undergo PSA screening should be made by both the provider and the patient, after a discussion of the limited benefits and associated harms. The interval of follow-up screening may vary from 2 to 4 years depending on patient age, level of PSA, and whether a patient is taking medications such as 5-alpha-reductase inhibitors.

It is important to note that the active monitoring that took place in ProtecT²³ was very different from the passive surveillance of PIVOT²⁴ and SPCG-4.²⁵ In ProtecT, once an elevated serum PSA level was noted, PSA levels were monitored every 3 months in the first year and every 6 to 12 months thereafter.²³ Triggers to reassess patients and consider a change in clinical management were based largely on changes in PSA levels. Participants with an increase of at least 50% in PSA level during the previous 12 months were offered either continued monitoring or treatment after further testing.

Making individualized decisions about prostate cancer screening

Traditionally, the goal of cancer screening has been to maximize the number of people screened. Generally, the information provided to patients about cancer screening emphasizes the benefits and minimizes the harms. Recently, however, there has been a shift in communication about cancer screening with the emphasis now being placed on informed decision-making and encouraging patients to make individual decisions about screening participation.²⁶

Although current guidelines regarding PSA screening differ by organization, generally speaking, PSA screening should be offered only to men with a life expectancy > 10 years.

The treatment option of active surveillance, with its lower incidence of adverse outcomes, is an important reason for patients to make individualized decisions about prostate cancer screening.

Another reason relates to 5-alpha-­reductase inhibitors. Although their role in the management of prostate cancer is currently not well defined, a reduction of almost 25% in the risk of prostate cancer and improvement in the performance of PSA has been reported.²⁷

The PSA test has low sensitivity and specificity and lacks a clear cut-off value that warrants prostate biopsy.

And yet another reason is that there are alternate strategies to manage the majority of patients who have been diagnosed with low-risk disease through transrectal ultrasound biopsy. The ERSPC study mentions multiparametric magnetic resonance imaging combined with targeted biopsy to identify high-grade disease.^28,29 Genetic and epigenetic assays of the biopsied tissue can help grade disease based on aggressiveness.³⁰ Transperineal mapping biopsy using a mapping software program can identify specific disease sites within the prostate gland, so that patients can be offered the option of targeted therapy.³⁰

Applying shared decision-making to prostate cancer screening

Balancing errors of omission with errors of commission is challenging. Shared decision-making (SDM) is an approach whereby clinicians and patients share the best available evidence when faced with the task of medical decision-making and in which patients are supported while they consider their options and achieve their preferences.³¹ SDM is well supported by evidence from a number of RCTs and results in increased knowledge, involvement, and confidence on the part of patients.³² An individualized approach using the schematic diagram (FIGURE 1^3,18) may be helpful.

Barriers to SDM success. Many factors can interfere with the success of SDM including limited or poor communication; lack of time during busy office visits; and patients’ cultural, informational, and/or emotional needs. To improve patient-centered communication, we can: (1) make information understandable and available to patients and families; (2) prioritize training in communication; (3) use decision aid tools to facilitate communication; and (4) work to improve the payment model to incentivize patient-centered communication. Tools that facilitate SDM include videotapes, patient group discussions, brief scripts read to patients, and informational pamphlets. One such tool is the American Society for Clinical Oncology’s decision aid tool for PSA testing.³³

Limited knowledge among patients. Decisions regarding treatment among men diagnosed with localized prostate cancer can be difficult because there are several treatment options with similar prognoses, but there are differences in adverse effects. One population-based cohort study of men with newly diagnosed localized prostate cancer found that most men had significant knowledge deficits regarding the survival benefits of the 2 major treatment options—surgery and radiation.³⁴ In a large population-based study, 38% of men with localized prostate cancer reported receiving help from their primary care providers in the decision-making process for treatment.³⁵

Learning to employ SDM. Elwyn et al proposed a 3-step model to incorporate SDM into clinical practice.³¹ They described key steps that include: choice talk (making sure patients are informed about the reasonable options), option talk (providing more detailed information about the options), and decision talk (supporting the work of patients considering their preferences and deciding what is best). Properly employing these methods requires training using simulations.³¹

The bottom line

Although current guidelines regarding PSA screening differ by organization, generally speaking PSA screening should be offered only to men with a life expectancy > 10 years. The PSA test has low sensitivity and specificity and lacks a clear cut-off value that warrants prostate biopsy. Men who choose to have PSA testing increase their chances of detecting prostate cancer, but most prostate cancers are slow growing and do not cause death. The decision to undergo PSA screening should be made by both the provider and the patient, after a discussion of the limited benefits and associated harms. The interval of follow-up screening may vary from 2 to 4 years depending on patient age, level of PSA, and whether a patient is taking medications such as 5-alpha-reductase inhibitors.

Attributed to the ancient Greek philosopher Heraclitus, and often quoted in contemporary times, is the expression “the only constant is change.” This sentiment rings true for the field of obstetrics this past year, as several bread-and-butter guidelines for managing common obstetric conditions were either challenged or altered.

The publication of the PROLONG trial called into question the use of intramuscular progesterone for the prevention of preterm birth. Prophylaxis guidelines for group B streptococcal disease were updated, including several significant clinical practice changes. Finally, there was a comprehensive overhaul of the guidelines for hypertensive disorders of pregnancy, which replaced a landmark Task Force document from the American College of Obstetricians and Gynecologists (ACOG) that was published only a few years ago.

Change is constant, and in obstetrics it is vital to keep up with the changing guidelines that result as new data become available for digestion and implementation into everyday clinical practice.

Results from the PROLONG trial may shake up treatment options for recurrent preterm birth 

Blackwell SC, Gyamfi-Bannerman C, Biggio JR Jr, et al. 17-OHPC to prevent recurrent preterm birth in singleton gestations (PROLONG study): a multicenter, international, randomized double-blind trial. Am J Perinatol. 2019. doi: 10.1055/s-0039-3400227. 

The drug 17 α-hydroxyprogesterone caproate (17-OHPC, or 17P; Makena) was approved by the US Food and Drug Administration (FDA) in 2011 for the prevention of spontaneous preterm birth (PTB) in women with a singleton pregnancy and a history of singleton spontaneous PTB. The results of the trial by Meis and colleagues of 17-OHPC played a major role in achieving that approval, as it demonstrated a 34% reduction in recurrent PTB and a reduction in some neonatal morbidities.¹ Following the drug's approval, both ACOG and the Society for Maternal-Fetal Medicine (SMFM) published guidelines recommending progesterone therapy, including 17-OHPC, for the prevention of recurrent spontaneous PTB.²   

The FDA approval of 17-OHPC was granted under an accelerated conditional pathway that required a confirmatory trial evaluating efficacy, safety, and long-term infant follow-up to be performed by the sponsor. That trial, Progestin's Role in Optimizing Neonatal Gestation (PROLONG), was started in 2009, and its results were published on October 25, 2019.³ 

Continue to: Design of the trial...

Design of the trial 

PROLONG was a multicenter (93 sites), randomized, placebo-controlled, double-blind study conducted in 9 countries (23% of participants were in the United States, 60% were in Russia and Ukraine). The co-primary outcome was PTB < 35 weeks and a composite neonatal morbidity and mortality index. The primary safety outcome was fetal/early infant death. 

The study was designed to have 98% power to detect a 30% reduction in PTB < 35 weeks, and 90% power to detect a 35% reduction in the neonatal composite index. It included 1,708 participants (1,130 were treated with 17-OHPC, and 578 received placebo). 

Trial outcomes. There was no difference in PTB < 35 weeks between the 17-OHPC and the placebo groups (11.0% vs 11.5%; relative risk [RR], 0.95; 95% confidence interval [CI], 0.71-1.26). There was no difference in PTB < 32 or < 37 weeks. 

The study revealed also that there was no difference between groups in the neonatal composite index (5.6% for 17-OHPC vs 5.0% for placebo; RR, 1.12; 95% CI, 0.68-1.61). In addition, there was no difference in fetal/early infant death between the 17-OHPC and placebo groups (1.7% vs 1.9%; RR, 0.87; 95% CI, 0.4-1.81). 

Conclusions. The trial investigators concluded that 17-OHPC did not demonstrate a reduction in recurrent PTB and did not decrease neonatal morbidity. 

Study limitations included underpowering and selection bias 

The investigators noted that the PTB rate in PROLONG was unexpectedly almost 50% lower than that in the Meis trial, and that therefore the PROLONG trial was underpowered to assess the primary outcomes. 

Further, the study populations of the 2 trials were very different: The Meis trial included women at higher baseline risk for PTB (> 1 prior PTB and at least 1 other risk factor for PTB). Additionally, while the PROLONG trial included mostly white (90%), married (90%), nonsmoking women (8% smoked), the Meis trial population was 59% black and 50% married, and 20% were smokers.  

The availability and common use of 17-OHPC in the United States likely led to a selection bias for the PROLONG trial population, as the highest-risk patients were most likely already receiving treatment and were therefore excluded from the PROLONG trial. 

Society, and FDA, responses to the new data 

The results of the PROLONG trial call into question what has become standard practice for patients with a history of spontaneous PTB in the United States. While the safety profile of 17-OHPC has not been cited as a concern, whether or not the drug should be used at all has—as has its current FDA-approved status. 

In response to the publication of the PROLONG trial results, ACOG released a Practice Advisory that acknowledged the study's findings but did not alter the current recommendations to continue to offer progesterone for the prevention of preterm birth, upholding ACOG's current Practice Bulletin guidance.^2,4 Additional considerations for offering 17-OHPC use include the patients' preferences, available resources, and the setting for the intervention.  

SMFM's response was more specific, stating that it is reasonable to continue to use 17-OHPC in high-risk patient populations consistent with those in the Meis trial.⁵ In the rest of the general population at risk for recurrent PTB, SMFM recommends that, due to uncertain benefit with 17-OHPC, the high cost, patient discomfort, and increased visits should be taken into account.  

Four days after the publication of the PROLONG study, the FDA Bone, Reproductive, and Urologic Drugs Advisory Committee voted 9-7 to withdraw approval for 17-OHPC.⁶ In response, SMFM released a statement supporting continued access to 17-OHPC.⁷ The FDA's final decision on the status of the drug is expected within the next several months from this writing.

ACOG updates guidance on preventing early-onset GBS disease 

American College of Obstetricians and Gynecologists—Committee on Obstetric Practice. ACOG committee opinion no. 782: prevention of early-onset group B streptococcal disease in newborns. Obstet Gynecol. 2019;134:e19-e40. 

Group B streptococcus (GBS) is the leading cause of newborn infection and is associated with maternal infections as well as preterm labor and stillbirth. Early-onset GBS disease occurs within 7 days of birth and is linked to vertical transmission via maternal colonization of the genitourinary or gastrointestinal tract and fetal/neonatal aspiration at birth.  

Preventing early-onset GBS disease with maternal screening and intrapartum prophylaxis according to the Centers for Disease Control and Prevention (CDC) guidelines has reduced early-onset disease by 80% since the 1990s. By contrast, late-onset GBS infection, which occurs 7 days to 3 months after birth, usually is associated with horizontal maternal transmission or hospital or community infections, and it is not prevented by intrapartum treatment. 

In 2018, the CDC transferred responsibility for GBS prophylaxis guidelines to ACOG and the American Academy of Pediatrics (AAP). In July 2019, ACOG released its Committee Opinion on preventing early-onset GBS disease in newborns.⁸ This guidance replaces and updates the previous guidelines, with 3 notable changes.  

The screening timing has changed 

In the CDC's 2010 guidelines, GBS screening was recommended to start at 35 weeks' gestation. The new guidelines recommend universal vaginal-rectal screening at 36 to 37 6/7 weeks' gestation. The new timing of culture will shift the expected 5-week window in which GBS cultures are considered valid up to at least 41 weeks' gestation. The rationale  for this change is that any GBS-unknown patient who previously would have been cultured under 37 weeks' would be an automatic candidate for empiric therapy and the lower rate of birth in the 35th versus the 41st week of gestation. 

Identifying candidates for intrapartum treatment 

The usual indications for intrapartum antibiotic prophylaxis include a GBS-positive culture at 36 weeks or beyond, GBS bacteriuria at any point in pregnancy, a prior GBS-affected child, or unknown GBS status with any of the following: < 37 weeks, rupture of membranes ≥ 18 hours or temperature ≥ 100.4°F (38°C), and a positive rapid GBS culture in labor. In addition, antibiotics now should be considered for patients at term with unknown GBS status but with a history of GBS colonization in a prior pregnancy.  

This represents a major practice change for women at ≥ 37 weeks with unknown GBS status and no other traditional risk factors. The rationale for this recommendation is that women who have been positive for GBS in a prior pregnancy have a 50% chance of being colonized in the current pregnancy, and their newborns are therefore at higher risk for early-onset GBS disease.  

Managing patients with penicillin allergy 

Intravenous penicillin (or ampicillin) remains the antibiotic of choice for intrapartum prophylaxis against GBS due to its efficacy and specific, narrow coverage of gram-positive organisms. The updated recommendations emphasize that it is important to carefully evaluate patients with reported penicillin allergies for several reasons: determining risk of anaphylaxis and clindamycin susceptibility testing in GBS evaluations are often overlooked by obstetric providers, the need for antibiotic stewardship to reduce the development of antibiotic resistance, and clarification of allergy status for future health care needs. 

Three recommendations are made: 

• Laboratory requisitions for cultures should specifically note a penicillin allergy so that clindamycin susceptibility testing can be performed. 
• Penicillin allergy skin testing should be considered for patients at unknown or low risk for anaphylaxis, as it is considered safe in pregnancy and most patients (80%-90%) who report a penicillin allergy are actually penicillin tolerant. 
• For patients at high risk for anaphylaxis to penicillin, the recommended vancomycin dosing has been changed from 1 g IV every 12 hours to 20 mg/kg IV every 8 hours (maximum single dose, 2 g). Renal function should be assessed prior to dosing. This weight- and renal function-based dosing increased neonatal therapeutic levels in several studies of different doses.

Managing hypertension in pregnancy: New recommendations  

American College of Obstetricians and Gynecologists. ACOG practice bulletin no. 202. Gestational hypertension and preeclampsia. Obstet Gynecol. 2019;133:e1-e25. 

In 2013, ACOG released "Hypertension in pregnancy," a 99-page comprehensive document developed by their Task Force on Hypertension in Pregnancy, to summarize knowledge on the subject, provide guidelines for management, and identify needed areas of research.⁹ I summarized key points from that document in the 2014 "Update on Obstetrics" (OBG Manag. 2013;26[1]:28-36). Now, ACOG has released 2 Practice Bulletins—"Gestational hypertension and preeclampsia" and "Chronic hypertension in pregnancy"—that replace the 2013 document.^10,11 These Practice Bulletins are quite comprehensive and warrant a thorough read. Several noteworthy changes relevant to the practicing obstetrician are summarized below. 

Highlights of revised guidance 

Expectant management vs early delivery in preeclampsia with fetal growth restriction. Fetal growth restriction, which was removed from the definition of preeclampsia with severe features in 2013, is no longer an indication for delivery in preeclampsia with severe features (previously, if the estimated fetal weight was < 5th percentile for gestational age, delivery after steroid administration was recommended). Rather, expectant management is reasonable if fetal antenatal testing, amniotic fluid, and Doppler ultrasound studies are reassuring. Abnormal umbilical artery Doppler studies continue to be an indication for earlier delivery. 

Postpartum NSAID use in hypertension. The 2013 document cautioned against nonsteroidal anti-inflammatory drug (NSAID) use postpartum in women with hypertensive disorders of pregnancy because of concern for exacerbating hypertension. The updated Practice Bulletins recommend NSAIDs as the preferred choice over opioid analgesics as data have not shown these drugs to increase blood pressure, antihypertensive requirements, or other adverse events in postpartum patients with blood pressure issues. 

More women will be diagnosed with chronic hypertension. Recently, the American College of Cardiology and the American Heart Association changed the definition of hypertension. Stage 1 hypertension is now defined as a systolic blood pressure of 130-139 mm Hg or a diastolic blood pressure of 80-89 mm Hg. Treatment of stage 1 hypertension is recommended for nonpregnant adults with risk factors for current or future cardiovascular disease. The potential impact is that more women will enter pregnancy with a diagnosis of chronic hypertension, and more may be on prepregnancy antihypertensive therapy that will need to be addressed during the pregnancy.  

Blood pressure goals. The target blood pressure range for pregnant women with chronic hypertension is recommended to be ≥ 120/80 mm Hg and < 160/110 mm Hg (this represents a slight change, as previously diastolic blood pressure was to be < 105 mm Hg). Postpartum blood pressure goals of < 150/100 mm Hg remain the same. 

Managing acute hypertensive emergencies. Both Practice Bulletins emphasize the importance of aggressive management of acute hypertensive emergency, with options for 3 protocols: labetalol, nifedipine, and hydralazine. The goal is to administer antihypertensive therapy within 30 to 60 minutes, but administration as soon as feasibly possible after diagnosis of severe hypertension is ideal. 

Timing of delivery. Recommended delivery timing in patients with chronic hypertension was slightly altered (previous recommendations included a range of 37 to 39 6/7 weeks). The lower limit of gestational age for recommended delivery timing in chronic hypertension has not changed—it remains not before 38 weeks if no antihypertensive therapy and stable, and not before 37 weeks if antihypertensive therapy and stable.  

The upper limit of 39 6/7 weeks is challenged, however, because data support that induction of labor at either 38 or 39 weeks reduces the risk of severe hypertensive complications (such as superimposed preeclampsia and eclampsia) without increasing the risk of cesarean delivery. Therefore, for patients with chronic hypertension, expectant management beyond 39 weeks is cautioned, to be done only with careful consideration of risks and with close surveillance. 

Attributed to the ancient Greek philosopher Heraclitus, and often quoted in contemporary times, is the expression “the only constant is change.” This sentiment rings true for the field of obstetrics this past year, as several bread-and-butter guidelines for managing common obstetric conditions were either challenged or altered.

Timing of delivery. Recommended delivery timing in patients with chronic hypertension was slightly altered (previous recommendations included a range of 37 to 39 6/7 weeks). The lower limit of gestational age for recommended delivery timing in chronic hypertension has not changed—it remains not before 38 weeks if no antihypertensive therapy and stable, and not before 37 weeks if antihypertensive therapy and stable.  

The upper limit of 39 6/7 weeks is challenged, however, because data support that induction of labor at either 38 or 39 weeks reduces the risk of severe hypertensive complications (such as superimposed preeclampsia and eclampsia) without increasing the risk of cesarean delivery. Therefore, for patients with chronic hypertension, expectant management beyond 39 weeks is cautioned, to be done only with careful consideration of risks and with close surveillance. 

Attributed to the ancient Greek philosopher Heraclitus, and often quoted in contemporary times, is the expression “the only constant is change.” This sentiment rings true for the field of obstetrics this past year, as several bread-and-butter guidelines for managing common obstetric conditions were either challenged or altered.

The publication of the PROLONG trial called into question the use of intramuscular progesterone for the prevention of preterm birth. Prophylaxis guidelines for group B streptococcal disease were updated, including several significant clinical practice changes. Finally, there was a comprehensive overhaul of the guidelines for hypertensive disorders of pregnancy, which replaced a landmark Task Force document from the American College of Obstetricians and Gynecologists (ACOG) that was published only a few years ago.

Change is constant, and in obstetrics it is vital to keep up with the changing guidelines that result as new data become available for digestion and implementation into everyday clinical practice.

Results from the PROLONG trial may shake up treatment options for recurrent preterm birth 

Blackwell SC, Gyamfi-Bannerman C, Biggio JR Jr, et al. 17-OHPC to prevent recurrent preterm birth in singleton gestations (PROLONG study): a multicenter, international, randomized double-blind trial. Am J Perinatol. 2019. doi: 10.1055/s-0039-3400227. 

The drug 17 α-hydroxyprogesterone caproate (17-OHPC, or 17P; Makena) was approved by the US Food and Drug Administration (FDA) in 2011 for the prevention of spontaneous preterm birth (PTB) in women with a singleton pregnancy and a history of singleton spontaneous PTB. The results of the trial by Meis and colleagues of 17-OHPC played a major role in achieving that approval, as it demonstrated a 34% reduction in recurrent PTB and a reduction in some neonatal morbidities.¹ Following the drug's approval, both ACOG and the Society for Maternal-Fetal Medicine (SMFM) published guidelines recommending progesterone therapy, including 17-OHPC, for the prevention of recurrent spontaneous PTB.²   

The FDA approval of 17-OHPC was granted under an accelerated conditional pathway that required a confirmatory trial evaluating efficacy, safety, and long-term infant follow-up to be performed by the sponsor. That trial, Progestin's Role in Optimizing Neonatal Gestation (PROLONG), was started in 2009, and its results were published on October 25, 2019.³ 

Continue to: Design of the trial...

Design of the trial 

PROLONG was a multicenter (93 sites), randomized, placebo-controlled, double-blind study conducted in 9 countries (23% of participants were in the United States, 60% were in Russia and Ukraine). The co-primary outcome was PTB < 35 weeks and a composite neonatal morbidity and mortality index. The primary safety outcome was fetal/early infant death. 

The study was designed to have 98% power to detect a 30% reduction in PTB < 35 weeks, and 90% power to detect a 35% reduction in the neonatal composite index. It included 1,708 participants (1,130 were treated with 17-OHPC, and 578 received placebo). 

Trial outcomes. There was no difference in PTB < 35 weeks between the 17-OHPC and the placebo groups (11.0% vs 11.5%; relative risk [RR], 0.95; 95% confidence interval [CI], 0.71-1.26). There was no difference in PTB < 32 or < 37 weeks. 

The study revealed also that there was no difference between groups in the neonatal composite index (5.6% for 17-OHPC vs 5.0% for placebo; RR, 1.12; 95% CI, 0.68-1.61). In addition, there was no difference in fetal/early infant death between the 17-OHPC and placebo groups (1.7% vs 1.9%; RR, 0.87; 95% CI, 0.4-1.81). 

Conclusions. The trial investigators concluded that 17-OHPC did not demonstrate a reduction in recurrent PTB and did not decrease neonatal morbidity. 

Study limitations included underpowering and selection bias 

The investigators noted that the PTB rate in PROLONG was unexpectedly almost 50% lower than that in the Meis trial, and that therefore the PROLONG trial was underpowered to assess the primary outcomes. 

Further, the study populations of the 2 trials were very different: The Meis trial included women at higher baseline risk for PTB (> 1 prior PTB and at least 1 other risk factor for PTB). Additionally, while the PROLONG trial included mostly white (90%), married (90%), nonsmoking women (8% smoked), the Meis trial population was 59% black and 50% married, and 20% were smokers.  

The availability and common use of 17-OHPC in the United States likely led to a selection bias for the PROLONG trial population, as the highest-risk patients were most likely already receiving treatment and were therefore excluded from the PROLONG trial. 

Society, and FDA, responses to the new data 

The results of the PROLONG trial call into question what has become standard practice for patients with a history of spontaneous PTB in the United States. While the safety profile of 17-OHPC has not been cited as a concern, whether or not the drug should be used at all has—as has its current FDA-approved status. 

In response to the publication of the PROLONG trial results, ACOG released a Practice Advisory that acknowledged the study's findings but did not alter the current recommendations to continue to offer progesterone for the prevention of preterm birth, upholding ACOG's current Practice Bulletin guidance.^2,4 Additional considerations for offering 17-OHPC use include the patients' preferences, available resources, and the setting for the intervention.  

SMFM's response was more specific, stating that it is reasonable to continue to use 17-OHPC in high-risk patient populations consistent with those in the Meis trial.⁵ In the rest of the general population at risk for recurrent PTB, SMFM recommends that, due to uncertain benefit with 17-OHPC, the high cost, patient discomfort, and increased visits should be taken into account.  

Four days after the publication of the PROLONG study, the FDA Bone, Reproductive, and Urologic Drugs Advisory Committee voted 9-7 to withdraw approval for 17-OHPC.⁶ In response, SMFM released a statement supporting continued access to 17-OHPC.⁷ The FDA's final decision on the status of the drug is expected within the next several months from this writing.

ACOG updates guidance on preventing early-onset GBS disease 

American College of Obstetricians and Gynecologists—Committee on Obstetric Practice. ACOG committee opinion no. 782: prevention of early-onset group B streptococcal disease in newborns. Obstet Gynecol. 2019;134:e19-e40. 

Group B streptococcus (GBS) is the leading cause of newborn infection and is associated with maternal infections as well as preterm labor and stillbirth. Early-onset GBS disease occurs within 7 days of birth and is linked to vertical transmission via maternal colonization of the genitourinary or gastrointestinal tract and fetal/neonatal aspiration at birth.  

Preventing early-onset GBS disease with maternal screening and intrapartum prophylaxis according to the Centers for Disease Control and Prevention (CDC) guidelines has reduced early-onset disease by 80% since the 1990s. By contrast, late-onset GBS infection, which occurs 7 days to 3 months after birth, usually is associated with horizontal maternal transmission or hospital or community infections, and it is not prevented by intrapartum treatment. 

In 2018, the CDC transferred responsibility for GBS prophylaxis guidelines to ACOG and the American Academy of Pediatrics (AAP). In July 2019, ACOG released its Committee Opinion on preventing early-onset GBS disease in newborns.⁸ This guidance replaces and updates the previous guidelines, with 3 notable changes.  

The screening timing has changed 

In the CDC's 2010 guidelines, GBS screening was recommended to start at 35 weeks' gestation. The new guidelines recommend universal vaginal-rectal screening at 36 to 37 6/7 weeks' gestation. The new timing of culture will shift the expected 5-week window in which GBS cultures are considered valid up to at least 41 weeks' gestation. The rationale  for this change is that any GBS-unknown patient who previously would have been cultured under 37 weeks' would be an automatic candidate for empiric therapy and the lower rate of birth in the 35th versus the 41st week of gestation. 

Identifying candidates for intrapartum treatment 

The usual indications for intrapartum antibiotic prophylaxis include a GBS-positive culture at 36 weeks or beyond, GBS bacteriuria at any point in pregnancy, a prior GBS-affected child, or unknown GBS status with any of the following: < 37 weeks, rupture of membranes ≥ 18 hours or temperature ≥ 100.4°F (38°C), and a positive rapid GBS culture in labor. In addition, antibiotics now should be considered for patients at term with unknown GBS status but with a history of GBS colonization in a prior pregnancy.  

This represents a major practice change for women at ≥ 37 weeks with unknown GBS status and no other traditional risk factors. The rationale for this recommendation is that women who have been positive for GBS in a prior pregnancy have a 50% chance of being colonized in the current pregnancy, and their newborns are therefore at higher risk for early-onset GBS disease.  

Managing patients with penicillin allergy 

Intravenous penicillin (or ampicillin) remains the antibiotic of choice for intrapartum prophylaxis against GBS due to its efficacy and specific, narrow coverage of gram-positive organisms. The updated recommendations emphasize that it is important to carefully evaluate patients with reported penicillin allergies for several reasons: determining risk of anaphylaxis and clindamycin susceptibility testing in GBS evaluations are often overlooked by obstetric providers, the need for antibiotic stewardship to reduce the development of antibiotic resistance, and clarification of allergy status for future health care needs. 

Three recommendations are made: 

• Laboratory requisitions for cultures should specifically note a penicillin allergy so that clindamycin susceptibility testing can be performed. 
• Penicillin allergy skin testing should be considered for patients at unknown or low risk for anaphylaxis, as it is considered safe in pregnancy and most patients (80%-90%) who report a penicillin allergy are actually penicillin tolerant. 
• For patients at high risk for anaphylaxis to penicillin, the recommended vancomycin dosing has been changed from 1 g IV every 12 hours to 20 mg/kg IV every 8 hours (maximum single dose, 2 g). Renal function should be assessed prior to dosing. This weight- and renal function-based dosing increased neonatal therapeutic levels in several studies of different doses.

Managing hypertension in pregnancy: New recommendations  

American College of Obstetricians and Gynecologists. ACOG practice bulletin no. 202. Gestational hypertension and preeclampsia. Obstet Gynecol. 2019;133:e1-e25. 

In 2013, ACOG released "Hypertension in pregnancy," a 99-page comprehensive document developed by their Task Force on Hypertension in Pregnancy, to summarize knowledge on the subject, provide guidelines for management, and identify needed areas of research.⁹ I summarized key points from that document in the 2014 "Update on Obstetrics" (OBG Manag. 2013;26[1]:28-36). Now, ACOG has released 2 Practice Bulletins—"Gestational hypertension and preeclampsia" and "Chronic hypertension in pregnancy"—that replace the 2013 document.^10,11 These Practice Bulletins are quite comprehensive and warrant a thorough read. Several noteworthy changes relevant to the practicing obstetrician are summarized below. 

Highlights of revised guidance 

Expectant management vs early delivery in preeclampsia with fetal growth restriction. Fetal growth restriction, which was removed from the definition of preeclampsia with severe features in 2013, is no longer an indication for delivery in preeclampsia with severe features (previously, if the estimated fetal weight was < 5th percentile for gestational age, delivery after steroid administration was recommended). Rather, expectant management is reasonable if fetal antenatal testing, amniotic fluid, and Doppler ultrasound studies are reassuring. Abnormal umbilical artery Doppler studies continue to be an indication for earlier delivery. 

Postpartum NSAID use in hypertension. The 2013 document cautioned against nonsteroidal anti-inflammatory drug (NSAID) use postpartum in women with hypertensive disorders of pregnancy because of concern for exacerbating hypertension. The updated Practice Bulletins recommend NSAIDs as the preferred choice over opioid analgesics as data have not shown these drugs to increase blood pressure, antihypertensive requirements, or other adverse events in postpartum patients with blood pressure issues. 

More women will be diagnosed with chronic hypertension. Recently, the American College of Cardiology and the American Heart Association changed the definition of hypertension. Stage 1 hypertension is now defined as a systolic blood pressure of 130-139 mm Hg or a diastolic blood pressure of 80-89 mm Hg. Treatment of stage 1 hypertension is recommended for nonpregnant adults with risk factors for current or future cardiovascular disease. The potential impact is that more women will enter pregnancy with a diagnosis of chronic hypertension, and more may be on prepregnancy antihypertensive therapy that will need to be addressed during the pregnancy.  

Blood pressure goals. The target blood pressure range for pregnant women with chronic hypertension is recommended to be ≥ 120/80 mm Hg and < 160/110 mm Hg (this represents a slight change, as previously diastolic blood pressure was to be < 105 mm Hg). Postpartum blood pressure goals of < 150/100 mm Hg remain the same. 

Managing acute hypertensive emergencies. Both Practice Bulletins emphasize the importance of aggressive management of acute hypertensive emergency, with options for 3 protocols: labetalol, nifedipine, and hydralazine. The goal is to administer antihypertensive therapy within 30 to 60 minutes, but administration as soon as feasibly possible after diagnosis of severe hypertension is ideal. 

Timing of delivery. Recommended delivery timing in patients with chronic hypertension was slightly altered (previous recommendations included a range of 37 to 39 6/7 weeks). The lower limit of gestational age for recommended delivery timing in chronic hypertension has not changed—it remains not before 38 weeks if no antihypertensive therapy and stable, and not before 37 weeks if antihypertensive therapy and stable.  

The upper limit of 39 6/7 weeks is challenged, however, because data support that induction of labor at either 38 or 39 weeks reduces the risk of severe hypertensive complications (such as superimposed preeclampsia and eclampsia) without increasing the risk of cesarean delivery. Therefore, for patients with chronic hypertension, expectant management beyond 39 weeks is cautioned, to be done only with careful consideration of risks and with close surveillance. 

Eating disorders affect nearly 1% of US adults,¹ and disordered eating, or unspecified eating disorder, affects at least 1% of all pregnancies.² Among 739 pregnant women assessed with the Eating Disorder Diagnostic scale, 7.5% of patients met criteria for an eating disorder, with 8.8% of women reporting binge eating and 2.3% of pregnant women engaging in regular compensatory behaviors. In fact, 23.4% of the study population expressed concerns about pregnancy-related weight gain and body shape.³ Eating disorders during pregnancy are more common than previously thought, and they create unique clinical challenges for obstetric providers.

Types of eating disorders

There are 3 major types of eating disorders: anorexia nervosa, bulimia nervosa, and binge eating disorder, with significant fluidity existing between all 3 conditions.

Anorexia nervosa is a condition in which an individual believes he or she is significantly overweight despite being underweight. Patients with anorexia nervosa often restrict food intake and have compulsive rituals around eating and exercise, leading to weight loss and starvation.⁴

Bulimia nervosa is marked by intensive dieting, uncontrolled episodes of overeating, and compensatory behaviors.⁴ Compensatory behaviors include self-induced vomiting; excessive exercise; and misuse of laxatives, diuretics, or other medications.

Binge eating disorder is classified as recurrent episodes of uncontrolled overeating without compensatory purging behaviors, leading to excessive weight gain.⁴

Eating disorders and pregnancy

Pregnancy can impact the course of pre­existing eating disorders, and women also can develop symptoms of eating disorders for the first time during pregnancy. This is clinically significant as there are both maternal and fetal consequences to a mother’s disordered eating.

The risks of anorexia nervosa include vitamin deficiencies (vitamin B12/folate), dehydration leading to renal injury and electrolyte imbalances, hypoglycemia, abnormal lipid profiles, cardiac arrhythmia, and even death. The mortality rate of patients with anorexia nervosa may approach 10%; however, death during pregnancy is quite rare.² Bulimia nervosa also carries the risks of protein and vitamin deficiencies, hypoglycemia and hyperglycemia, and death, with mortality estimated at 7% for those with a 5-year history of the illness. However, death in pregnancy due to the condition is again quite rare.⁵

Eating disorders can cause significant maternal and fetal complications during pregnancy and postpartum.

Maternal complications. When women with eating disorders become pregnant, they have increased risks of some pregnancy complications. Approximately 10% to 25% of pregnant women with eating disorders develop hyperemesis gravidarum.⁶ The nausea can serve as a trigger for a woman with an eating disorder, particularly among women with a history of purging behaviors.

Cesarean delivery is more common among women with eating disorders, which may be due to preexisting fetal compromise, leading to poor tolerance of labor, or to clinicians perceiving these pregnancies as higher risk.⁷

It is well known that eating disorders are highly comorbid with depression and other psychiatric conditions. In fact, 30% to 40% of women with an eating disorder develop symptoms of postpartum depression.⁸

Continue to: Fetal risks and complications...

Fetal risks and complications. Excessive caloric restriction and dieting can lead to folate deficiency, which in turn increases the risk of neural tube defects. Such defects are more common among women with eating disorders.⁹ Intrauterine growth restriction also can be a concern, most likely because of maternal malnutrition and poor maternal weight gain.¹⁰ In addition, women with eating disorders are more likely to have a preterm delivery or experience perinatal mortality or stillbirth.¹⁰

Bulimia nervosa is associated with low birthweight, while anorexia nervosa is associated with the very premature birth, low birthweight, and perinatal death.¹¹ Eating disorders during pregnancy can have long-term psychological impacts on children, including increased likelihood of childhood hyperactivity, conduct, and adjustment disorder.¹²

Assessing patients for an eating disorder

Diagnosis of eating disorders is an interview-guided process using clinical criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th edition.⁴ The Eating Disorder Examination is a semi-structured interview composed of 4 subsections (restraint, eating concern, shape concern, and weight concern). The interview’s aim is to assess the psychopathology associated with eating disorders, and it is used in research settings rather than clinically.

1. Do you make yourself sick because you feel uncomfortably full?
2. Do you worry that you have lost control over how much you eat?
3. Have you recently lost more than one stone (14 lb) in a 3-month period?
4. Do you believe yourself to be fat when others say you are too thin?
5. Would you say that food dominates your life?

Referral. Patients for whom you have a concern for any eating disorder should be referred to a psychiatrist for formal diagnosis. Integrated multidisciplinary care of pregnant patients with eating disorders is necessary to improve maternal and fetal outcomes. Care teams should include obstetricians or maternal-fetal medicine clinicians experienced in caring for patients with eating disorders, psychiatrists, psychologists, nutritionists, and social workers. General treatment principles require an assessment for appropriate setting of intervention, which depends on presentation severity, assessment of nutritional status, treatment of psychiatric comorbidity, and psychotherapeutic intervention.

Overall management strategy

The initial treatment strategy for pregnant women with eating disorders should involve evaluating for severe illness and life-threatening complications of the specific disorder. All patients should be screened for suicidal ideation, severe malnutrition, electrolyte abnormalities, dehydration, hemodynamic instability, and cardiac arrhythmia. Patients with any of these severe features should be admitted for medical hospitalization and psychiatric evaluation.¹⁴ Patients that are hospitalized should be watched closely for refeeding syndrome—potentially life threatening metabolic disturbances that occur when nutrition is reinstituted to patients who are severely malnourished.

Patients without severe features or acute life-threatening complications can be managed safely on an outpatient basis with close medical monitoring. Psychiatric providers should be involved to assess for treatment needs including psychotherapy and psychotropic medications. There are numerous pharmacologic options available for patients, with the use of selective serotonin reuptake inhibitors (SSRIs) most common. While SSRI use has been controversial in pregnancy in the past, the risks of untreated illness carry risk to the mother and unborn child that outweigh the small risks associated with SSRI exposure in pregnancy.¹⁵

Women should have established care with a nutritionist or dietician who can ensure adequate counseling regarding meal planning and multivitamin supplementation. The numerous food restrictions in pregnancy, such as avoidance of unpasteurized cheese or deli meats, may be triggering for many patients with a history of restrictive eating.

One of the greatest difficulties for women with disordered eating in pregnancy revolves around weight gain. Many patients find the various measurements of pregnancy (maternal weight gain, fetal weight, fetal heart rate, and fundal height) triggering, which can make appropriate maternal and fetal weight gain in pregnancy very challenging. One strategy for managing this includes using fetal weight and growth as a surrogate for appropriate maternal gestational weight gain. One other strategy involves blind weights, where the woman is turned away from the scale so her weight is not disclosed to her. Patients often will not be able to achieve the expected 28 to 40 lb of pregnancy weight gain. It is best to have an open, honest conversation in early pregnancy to discuss how she would like to address weight in her pregnancy.

Continue to: Postpregnancy concerns...

Postpregnancy concerns

Patients with eating disorders are at high risk of relapse in the postpartum period, even if they are able to achieve full remission in pregnancy. Rapid postpartum weight loss may be a sign of disordered eating. Postpartum depression also is a concern, and women should be followed closely for surveillance of symptoms. Finally, postpartum contraception is extremely important. The menstrual irregularities that are common among women with eating disorders along with common misconceptions regarding fertility in the postpartum period increase the risk of unplanned pregnancy.

Remain cognizant of eating disorders

A clear surveillance plan early in the pregnancy that is developed in conjunction with the patient and her care team is crucial in improving maternal and fetal outcomes among women with an eating disorder. Clinician knowledge of complications and risks specific to disordered eating and pregnancy can affect outcomes for both mother and baby.

Bulimia nervosa is associated with low birthweight, while anorexia nervosa is associated with the very premature birth, low birthweight, and perinatal death.¹¹ Eating disorders during pregnancy can have long-term psychological impacts on children, including increased likelihood of childhood hyperactivity, conduct, and adjustment disorder.¹²

Assessing patients for an eating disorder

Diagnosis of eating disorders is an interview-guided process using clinical criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th edition.⁴ The Eating Disorder Examination is a semi-structured interview composed of 4 subsections (restraint, eating concern, shape concern, and weight concern). The interview’s aim is to assess the psychopathology associated with eating disorders, and it is used in research settings rather than clinically.

1. Do you make yourself sick because you feel uncomfortably full?
2. Do you worry that you have lost control over how much you eat?
3. Have you recently lost more than one stone (14 lb) in a 3-month period?
4. Do you believe yourself to be fat when others say you are too thin?
5. Would you say that food dominates your life?

Referral. Patients for whom you have a concern for any eating disorder should be referred to a psychiatrist for formal diagnosis. Integrated multidisciplinary care of pregnant patients with eating disorders is necessary to improve maternal and fetal outcomes. Care teams should include obstetricians or maternal-fetal medicine clinicians experienced in caring for patients with eating disorders, psychiatrists, psychologists, nutritionists, and social workers. General treatment principles require an assessment for appropriate setting of intervention, which depends on presentation severity, assessment of nutritional status, treatment of psychiatric comorbidity, and psychotherapeutic intervention.

Overall management strategy

The initial treatment strategy for pregnant women with eating disorders should involve evaluating for severe illness and life-threatening complications of the specific disorder. All patients should be screened for suicidal ideation, severe malnutrition, electrolyte abnormalities, dehydration, hemodynamic instability, and cardiac arrhythmia. Patients with any of these severe features should be admitted for medical hospitalization and psychiatric evaluation.¹⁴ Patients that are hospitalized should be watched closely for refeeding syndrome—potentially life threatening metabolic disturbances that occur when nutrition is reinstituted to patients who are severely malnourished.

Patients without severe features or acute life-threatening complications can be managed safely on an outpatient basis with close medical monitoring. Psychiatric providers should be involved to assess for treatment needs including psychotherapy and psychotropic medications. There are numerous pharmacologic options available for patients, with the use of selective serotonin reuptake inhibitors (SSRIs) most common. While SSRI use has been controversial in pregnancy in the past, the risks of untreated illness carry risk to the mother and unborn child that outweigh the small risks associated with SSRI exposure in pregnancy.¹⁵

Women should have established care with a nutritionist or dietician who can ensure adequate counseling regarding meal planning and multivitamin supplementation. The numerous food restrictions in pregnancy, such as avoidance of unpasteurized cheese or deli meats, may be triggering for many patients with a history of restrictive eating.

One of the greatest difficulties for women with disordered eating in pregnancy revolves around weight gain. Many patients find the various measurements of pregnancy (maternal weight gain, fetal weight, fetal heart rate, and fundal height) triggering, which can make appropriate maternal and fetal weight gain in pregnancy very challenging. One strategy for managing this includes using fetal weight and growth as a surrogate for appropriate maternal gestational weight gain. One other strategy involves blind weights, where the woman is turned away from the scale so her weight is not disclosed to her. Patients often will not be able to achieve the expected 28 to 40 lb of pregnancy weight gain. It is best to have an open, honest conversation in early pregnancy to discuss how she would like to address weight in her pregnancy.

Postpregnancy concerns

Patients with eating disorders are at high risk of relapse in the postpartum period, even if they are able to achieve full remission in pregnancy. Rapid postpartum weight loss may be a sign of disordered eating. Postpartum depression also is a concern, and women should be followed closely for surveillance of symptoms. Finally, postpartum contraception is extremely important. The menstrual irregularities that are common among women with eating disorders along with common misconceptions regarding fertility in the postpartum period increase the risk of unplanned pregnancy.

Remain cognizant of eating disorders

A clear surveillance plan early in the pregnancy that is developed in conjunction with the patient and her care team is crucial in improving maternal and fetal outcomes among women with an eating disorder. Clinician knowledge of complications and risks specific to disordered eating and pregnancy can affect outcomes for both mother and baby.

CASE New mother receives unneeded opioids after CD

A house officer wrote orders for a healthy patient who had just had an uncomplicated cesarean delivery (CD). The hospital’s tradition dictates orders for oxycodone plus acetaminophen tablets in addition to ibuprofen for all new mothers. At the time of the patient’s discharge, the same house officer prescribed 30 tablets of oxycodone plus acetaminophen “just in case,” although the patient had required only a few tablets while in the hospital on postoperative day 2 and none on the day of discharge.

Stuck in the habit

Prescribing postpartum opioids in the United States is almost habitual. Both optimizing patient satisfaction and minimizing patient phone calls may be driving this well-established pattern. Interestingly, a survey study of obstetric providers in 14 countries found that clinicians in 13 countries prescribe opioids “almost never” after vaginal delivery.¹ The United States was the 1 outlier, with providers reporting prescribing opioids “on a regular basis” after vaginal birth. Similarly, providers in 10 countries reported prescribing opioids “almost never” after CD, while those in the United States reported prescribing opioids “almost always” in this context.

Moreover, mounting data suggest that many patients do not require the quantity of opioids prescribed and that our overprescribing may be causing more harm than good.

The problem of overprescribing opioids after childbirth

Opioid analgesia has long been the mainstay of treatment for postpartum pain, which when poorly controlled is associated with the development of postpartum depression and chronic pain.² However, common adverse effects of opioids, including nausea, drowsiness, and dizziness, similarly can interfere with self-care and infant care. Of additional concern, a 2016 claims data study found that 1 of 300 opioid-naïve women who were prescribed opioids at discharge after CD used these medications persistently in the first year postpartum.³

Many women do not use the opioids that are prescribed to them at discharge, thus making tablets available for potential diversion into the community—a commonly recognized source of opioid misuse and abuse.^4,5 In a 2018 Committee Opinion on postpartum pain management, the American College of Obstetricians and Gynecologists (ACOG) stated that “a stepwise, multimodal approach emphasizing nonopioid analgesia as first-line therapy is safe and effective for vaginal deliveries and cesarean deliveries.”⁶ The Committee Opinion also asserted that “opioid medication is an adjunct for patients with uncontrolled pain despite adequate first-line therapy.”⁶

Despite efforts by the Centers for Disease Control and Prevention (CDC) and ACOG to improve opioid prescribing patterns after childbirth, the vast majority of women receive opioids in the hospital and at discharge not only after CD, but after vaginal delivery as well.^4,7 Why has tradition prevailed over data, and why have we not changed?

Continue to: Common misconceptions about reducing opioid use...

Common misconceptions about reducing opioid use

Two misconceptions persist regarding reducing opioid prescriptions for postpartum pain.

Misconception #1: Patients will be in pain

Randomized controlled trials that compared nonopioid with opioid regimens in the emergency room setting and opioid use after outpatient general surgery procedures have demonstrated that pain control for patients receiving opioids was equivalent to that for patients with pain managed with nonopioid regimens.^8-10 In the obstetric setting, a survey study of 720 women who underwent CD found that higher quantities of opioid tablets prescribed at discharge were not associated with improved pain, higher satisfaction, or lower refill rates at 2 weeks postpartum.⁴ However, greater quantities of opioids prescribed at the time of discharge were associated with greater opioid consumption.

Recently, several quality improvement studies implemented various interventions and successfully decreased postpartum opioid consumption without compromising pain management. One quality improvement project eliminated the routine use of opioids after CD and decreased the proportion of patients using any opioids in the hospital from 68% to 45%, with no changes in pain scores.¹¹ A similar study implemented an enhanced recovery after surgery (ERAS) program for women after CD; mean in-patient opioid use decreased from 10.7 to 5.4 average daily morphine equivalents, with improvement in the proportion of time that patients reported their pain as acceptable.¹²

Misconception #2: Clinicians will be overwhelmed with pages and phone calls

Providers commonly fear that decreasing opioid use will lead to an increased volume of pages and phone calls from patients requesting additional medication. However, data suggest otherwise. For example, a quality improvement study that eliminated the routine use of opioids after CD tracked the number of phone calls that were received requesting rescue opioid prescriptions after discharge.¹¹ Although the percentage of women discharged with opioids decreased from 90.6% to 40.3%, the requests for rescue opioid prescriptions did not change. Of 191 women, 4 requested a rescue prescription prior to the intervention compared with no women after the intervention. At the same time, according to unpublished data (Dr. Holland), satisfaction among nurses, house staff, and faculty did not change.

Similarly, a quality improvement project that implemented shared decision-making to inform the quantity of opioids prescribed at discharge demonstrated that the number of tablets prescribed decreased from 33.2 to 26.5, and there was no change in the rate of patients requesting opioid refills.¹³

Success stories: Strategies for reducing opioid use after childbirth

While overall rates of opioid prescribing after vaginal delivery and CD remain high throughout the United States, various institutions have developed successful and reproducible strategies to reduce opioid use after childbirth both in the hospital and at discharge. We highlight 3 strategies below.

Strategy 1: ERAS initiatives

An integrated health care system in northern California studied the effects of an ERAS protocol for CD across 15 medical centers.¹² The intervention centered on 4 pillars: multimodal pain management, early mobility, optimal nutrition, and patient engagement through education. Specifically, multimodal pain management consisted of the following:

• intrathecal opioids during CD
• scheduled intravenous acetaminophen for 24 hours followed by oral acetaminophen every 6 hours
• nonsteroidal anti-inflammatory drugs (NSAIDs) every 6 hours
• oral oxycodone for breakthrough pain
• decoupling of opioid medication from nonopioids in the post-CD order set
• decoupling of opioid and nonopioid medications in the discharge order set along with a reduction from 30 to 20 tablets as the default discharge quantity.

Continue to: Among 4,689 and 4,624 patients who underwent CD...

Among 4,689 and 4,624 patients who underwent CD before and after the intervention, the daily morphine milligram equivalents (MME) consumed in the hospital decreased from 10.7 to 5.4. The percentage of women who required no opioids while in the hospital increased from 8.3% to 21.4% after ERAS implementation, while the percentage of time that patients reported acceptable pain scores increased from 82.1% to 86.4%. The average number of opioid tablets prescribed at discharge also decreased, from 37 to 26 MME.¹² (The TABLE shows oxycodone doses converted to MMEs.)

Strategy 2: Order set change to eliminate routine use of opioids

A tertiary care center in Boston, Massachusetts, implemented a quality improvement project aimed at eliminating the routine use of opioid medication after CD through an order set change.¹¹ The intervention consisted of the following:

• intrathecal morphine
• multimodal postoperative pain management including scheduled oral acetaminophen for 72 hours followed by as-needed oral acetaminophen, scheduled NSAIDs for 72 hours followed by as-needed NSAIDs
• no postoperative order for opioids unless the patient had a contraindication to acetaminophen or NSAIDs, had a history of opioid dependence, or underwent complex surgery
• counseling patients that opioids were available for breakthrough pain if needed. In this case, nursing staff would page the responding clinician, who would order oxycodone 5 mg every 6 hours for 6 doses.
• specific criteria for discharge quantities of opioids: if the patient required no opioids in the hospital, she received no opioids at discharge; if the patient required opioids in the hospital but none at the time of discharge, she received no more than 10 tablets of oxycodone 5 mg; if the patient required opioids at the time of discharge, she received a maximum of 20 tablets of oxycodone 5 mg.

Among 191 and 181 women undergoing CD before and after the intervention, the percentage of patients who received any opioids in the hospital decreased from 68.1% to 45.3%.¹¹ Similarly, the percentage of patients receiving a discharge prescription for opioids decreased from 90.6% to 40.3%, while patient pain scores and satisfaction with pain control remained unchanged.

Strategy 3: Shared decision-making tool

Another tertiary care center in Boston evaluated the effects of a shared decision-making tool on opioid discharge prescribing after CD.¹⁵ The intervention consisted of a 10-minute clinician-facilitated session incorporating:

• education around anticipated patterns of postoperative pain
• expected outpatient opioid use after CD
• risks and benefits of opioids and nonopioids
• education around opioid disposal and access to refills.

Among the 50 women enrolled in the study, the number of oxycodone 5-mg tablets prescribed at discharge decreased from the institutional standard of 40 to 20. Ninety percent of women reported being satisfied or very satisfied with their pain control, while only 4 of 50 women required an opioid refill. A follow-up quality improvement project, which implemented the shared decision-making model along with a standardized multimodal pain management protocol, demonstrated a similar decrease in the quantity of opioids prescribed at discharge.¹³

Change is here to stay: A new culture of postpartum analgesia

The CDC continues to champion responsible opioid prescribing, while ACOG advocates for a reassessment of the way that opioids are utilized postpartum. The majority of women in the United States, however, continue to receive opioids after both vaginal delivery and CD. Consciously or not, we clinicians may be contributing to an outdated tradition that is potentially harmful both to patients and society. Reproducible strategies exist to reduce opioid use without compromising pain control or overwhelming clinicians with phone calls. It is time to embrace the change.

Medical malpractice (more formally, professional liability, but we will use the term malpractice) has been of concern to ObGyns for many years, and for good reasons. This specialty has some of the highest incidents of malpractice claims, some of the largest verdicts, and some of the highest malpractice insurance rates. We look more closely at ObGyn malpractice issues in a 3-part “What’s the Verdict” series over the next few months.

In part 1, we discuss the background on malpractice and reasons why malpractice rates have been so high—including large verdicts and lawsuit-prone physicians. In the second part we will look at recent experience and developments in malpractice exposure—who is sued and why. Finally, in the third part we will consider suggestions for reducing the likelihood of a malpractice lawsuit, with a special focus on recent research regarding apologies.

Two reports of recent trials involving ObGyn care illustrate the risk of “the big verdict.”^1,2 (Note that the following vignettes are drawn from actual cases but are outlines of those cases and not complete descriptions of the claims.

CASE 1 Delayed delivery, $19M verdict

At 39 weeks’ gestation, a woman was admitted to the hospital in spontaneous labor. Artificial rupture of membranes with clear amniotic fluid was noted. Active contractions occurred for 11 hours. Oxytocin was then initiated, and 17 minutes later, profound fetal bradycardia was detected. There was recurrent evidence of fetal distress with meconium. After a nursing staff change a second nurse restarted oxytocin for a prolonged period. The physician allowed labor to continue despite fetal distress, and performed a cesarean delivery (CD) 4.5 hours later. Five hours postdelivery the neonate was noted to have a pneumothorax, lung damage, and respiratory failure. The infant died at 18 days of age.

The jury felt that there was negligence—failure to timely diagnose fetal distress and failure to timely perform CD, all of which resulted in a verdict for the plaintiff. The jury awarded in excess of $19 million.¹

CASE 2 An undiagnosed tumor, $20M verdict

A patient underwent bilateral mastectomy. Following surgery, she reported pain and swelling at the surgical site for 2 years, and the defendant physician “dismissed” her complaint, refusing to evaluate it as the provider felt it was related to scar tissue. Three years after the mastectomies, the patient underwent surgical exploration and removal of 3 ribs and sternum secondary to a desmoid tumor. Surgical mesh and chest reconstruction was required, necessitating long-term opioids and sleeping medications that “will slow her wits, dull her senses and limit activities of daily living.” Of note, discrepancies were found in the medical records maintained by the defendant. (There was, for example, no report in the record of the plaintiff’s pain until late in the process.) The plaintiff based her claim on the fact that her pain and lump were neither evaluated nor discovered until it was too late.

The jury awarded $20 million. The verdict was reduced to $2 million by the court based on state statutory limits on malpractice damages.^2,3

Medical malpractice: Evolution of a standard of care

Medical malpractice is not a modern invention. Some historians trace malpractice to the Code of Hammurabi (2030 BC), through Roman law,⁴ into English common law.⁵ It was sufficiently established by 1765 that the classic legal treatise of the century referred to medical malpractice.^6,7 Although medical malpractice existed for a long time, actual malpractice cases were relatively rare before the last half of the 20th century.⁸

Defensive medicine born out of necessity. The number of malpractice cases increased substantially—described as a “geometric increase”—after 1960, with a 300% rise between 1965 and 1970.^7,9 This “malpractice maelstrom of the 70s”⁷ resulted in dramatic increases in malpractice insurance costs and invited the practice of defensive medicine—medically unnecessary or unjustified tests and services.¹⁰Although there is controversy about what is defensive medicine and what is reasonably cautious medicine, the practice may account for 3% of total health care spending.¹¹ Mello and others have estimated that there may be a $55 billion annual cost related to the medical malpractice system.¹²

Several malpractice crises and waves of malpractice or tort reform ensued,¹³ beginning in the 1970s and extending into the 2000s.¹¹ Malpractice law is primarily a matter of state law, so reform essentially has been at the state level—as we will see in the second part in this series.

Defining a standard of care

Medical malpractice is the application of standard legal principles to medical practice. Those principles generally are torts (intentional torts and negligence), and sometimes contracts.¹⁴ Eventually, medical malpractice came to focus primarily on negligence. The legal purposes of imposing negligence liability are compensation (to repay the plaintiff the costs of the harm caused by the defendant) and deterrence (to discourage careless conduct that can harm others.)

Negligence is essentially carelessness that falls below the acceptable standard of care. Negligence may arise, for example, from¹⁵:

• doing something (giving a drug to a patient with a known allergy to it)
• not doing something (failing to test for a possible tumor, as in the second case above)
• not giving appropriate informed consent
• failing to conduct an adequate examination
• abandoning a patient
• failing to refer a patient to a specialist (or conduct a consultation).

(In recent years, law reforms directed specifically at medical malpractice have somewhat separated medical malpractice from other tort law.)

In malpractice cases, the core question is whether the provider did (or did not) do something that a reasonably careful physician would have done. It is axiomatic that not all bad outcomes are negligent. Indeed, not all mistakes are negligent—only the mistakes that were unreasonable given all of the circumstances. In the first case above, for example, given all of the facts that preceded it, the delay of the physician for 4.5 hours after the fetal distress started was, as seen by the jury, not just a mistake but an unreasonable mistake. Hence, it was negligent. In the second case, the failure to investigate the pain and swelling in the surgical site for 2 years (or failure to refer the patient to another physician) was seen by the jury as an unreasonable mistake—one that would not have been made by a reasonably careful practitioner.

Continue to: The big verdict...

The big verdict

Everyone—every professional providing service, every manufacturer, every driver—eventually will make an unreasonable mistake (ie, commit negligence). If that negligence results in harming someone else, our standard legal response is that the negligent person should be financially responsible for the harm to the other. So, a driver who fails to stop at a red light and hits another car is responsible for those damages. But the damages may vary—perhaps a banged-up fender, or, in another instance, with the same negligence, perhaps terrible personal injuries that will disable the other driver for life. Thus, the damages can vary for the same level of carelessness. The “big verdict” may therefore fall on someone who was not especially careless.

Big verdicts often involve long-term care. The opening case vignettes illustrate a concern of medical malpractice generally—especially for ObGyn practice—the very high verdict. Very high verdicts generally reflect catastrophic damages that will continue for a long time. Bixenstine and colleagues found, for example, that catastrophic payouts often involved “patient age less than 1 year, quadriplegia, brain damage, or lifelong care.”¹⁶ In the case of serious injuries during delivery, for example, the harm to the child may last a lifetime and require years and years of intensive medical services.

Million-dollar-plus payouts are on the rise. The percentage of paid claims (through settlement or trial) that are above $1 million is increasing. These million-dollar cases represent 36% of the total dollars paid in ObGyn malpractice claims, even though they represent only 8% of the number of claims paid.¹⁶ The increase in the big verdict cases (above $1 million) suggests that ObGyn practition­ers should consider their malpractice policy limits—a million dollars may not be enough.

In big verdict cases, the great harm to the plaintiff is often combined with facts that produce extraordinary sympathy for the plaintiff. Sometimes there is decidedly unsympathetic conduct by the defendant as well. In the second case, for example, the problems with the medical record may have suggested to the jury that the doctor was either trying to hide something or did not care enough about the patient even to note a serious complaint. In a case we reviewed in an earlier “What’s the Verdict” column, a physician left the room for several minutes during a critical time—to take a call from a stockbroker.^16-18

The big verdict does not necessarily suggest that the defendant was especially or grossly negligent.¹⁶ It was a bad injury that occurred, for instance. On the other hand, the physician with several malpractice judgments may suggest that this is a problem physician.

Physicians facing multiple lawsuits are the exceptions

A number of studies have demonstrated that only a small proportion of physicians are responsible for a disproportionate number of paid medical malpractice claims. (“Paid claims” are those in which the plaintiff receives money from the doctor’s insurance. “Filed claims” are all malpractice lawsuits filed. Many claims are filed, but few are paid.)

ObGyn has high number of paid claims and high risk of claim payment recurrence. Studdert and colleagues found that the probability of future paid malpractice climbed with each past paid claim.¹⁹ They also found that 1% of physicians accounted for 32% of all paid claims. The number of paid claims varied by specialty—obstetrics and gynecology accounted for the second largest number of paid claims (13%). The risk of recurrence (more than one paid claim) was highest among 4 surgical specialties and ObGyns (about double the recurrence rate in these specialties compared with internal medicine).¹⁹

A minority of physicians responsible for lion share of paid claims. Black and colleagues followed up the Studdert study. Although there were some differences in what they found, the results were very similar.²⁰ For example, they found that having even a single prior paid claim strongly predicted future claims over the next 5 years. They also found that some “outlier” physicians with multiple paid claims “are responsible for a significant share of paid claims.” They specifically found that, even for physicians in high-risk specialties in high-risk states, “bad luck is highly unlikely to explain” multiple claims within 5 years.

Continue to: Both of the studies just mentioned relied on...

Both of the studies just mentioned relied on the National Practitioner Data Bank for information about paid claims. This source has some limitations in capturing claims or payments made by hospitals or other institutions for the actions of its agent-physicians. Some of these limitations were resolved in another recent study that looked at Indiana state insurance and licensing discipline records (over a 41-year period).²¹ Not surprisingly, this study found that claims paid increase with more severe licensure discipline. On the other hand, although, the “frequent fliers” in terms of malpractice claims made and paid could be identified as a “small number of repeat defendants,” these physicians were not routinely disciplined by the state medical board. This was only a single state study, of course, but it also found that a few physicians accounted for a significant number of the claims. The state board was not taking licensing action against this small group, however.

Should the few bad apples be picked from the orchard?

Collectively, these studies are fairly overwhelming in demonstrating that there are some physicians who are “prone” to malpractice claims (for whom all physicians in the specialty are probably paying higher malpractice rates), but who do not attract the attention of licensing agencies for careful examination. In addition to its self-interest in eliminating physicians prone to malpractice claims and payments, the obligation of professions to protect the public interest suggests that state boards should be more aggressive in pursuing those physicians practicing risky medicine.

This medical malpractice series will continue next month with a look at how to reduce malpractice exposure.

Medical malpractice (more formally, professional liability, but we will use the term malpractice) has been of concern to ObGyns for many years, and for good reasons. This specialty has some of the highest incidents of malpractice claims, some of the largest verdicts, and some of the highest malpractice insurance rates. We look more closely at ObGyn malpractice issues in a 3-part “What’s the Verdict” series over the next few months.

In part 1, we discuss the background on malpractice and reasons why malpractice rates have been so high—including large verdicts and lawsuit-prone physicians. In the second part we will look at recent experience and developments in malpractice exposure—who is sued and why. Finally, in the third part we will consider suggestions for reducing the likelihood of a malpractice lawsuit, with a special focus on recent research regarding apologies.

Two reports of recent trials involving ObGyn care illustrate the risk of “the big verdict.”^1,2 (Note that the following vignettes are drawn from actual cases but are outlines of those cases and not complete descriptions of the claims. Because the information does not come from formal court records, the facts may be inaccurate and are incomplete; they should be viewed as illustrations only.)

The ketogenic diet has been therapeutically employed by physicians since the times of Hippocrates, primarily for its effect on the nervous system.¹ The neurologic literature is inundated with the uses of this medicinal diet for applications in the treatment of epilepsy, neurodegenerative disease, malignancy, and enzyme deficiencies, among others.² In recent years, physicians and scientists have moved to study the application of a ketogenic diet in the realms of cardiovascular disease,³ autoimmune disease,⁴ management of diabetes mellitus (DM) and obesity,^3,5 and enhancement of sports and combat performance,⁶ all with promising results. Increased interest in alternative therapies among the lay population and the efficacy purported by many adherents has spurred intrigue by health care professionals. Over the last decade, there has seen a boom in so-called holistic approaches to health; included are the Paleo Diet, Primal Blueprint Diet, Bulletproof Diet, and the ketogenic/low-carbohydrate, high-fat diet. The benefits of ketones in these diets—through intermittent fasting or cyclical ketosis—–for cognitive enhancement, overall well-being, amelioration of chronic disease states, and increased health span have been promulgated to the lay population. But to date, there is a large gap in the literature on the applications of ketones as well as the ketogenic diet in dermatology and skin health and disease.

The aim of this article is not to summarize the uses of ketones and the ketogenic diet in dermatologic applications (because, unfortunately, those studies have not been undertaken) but to provide evidence from all available literature to support the need for targeted research and to encourage dermatologists to investigate ketones and their role in treating skin disease, primarily in an adjunctive manner. In doing so, a clearly medicinal diet may gain a foothold in the disease-treatment repertoire and among health-promoting agents of the dermatologist. Given the amount of capital being spent on health care, there is an ever-increasing need for low-cost, safe, and tolerable treatments that can be used for multiple disease processes and to promote health. We believe the ketogenic diet is such an adjunctive therapeutic option, as it has clearly been proven to be tolerable, safe, and efficacious for many people over the last millennia.

We conducted a PubMed search of articles indexed for MEDLINE using varying combinations of the terms ketones, ketogenic, skin, inflammation, metabolic, oxidation, dermatology, and dermatologic and found 12 articles. Herein, we summarize the relevant articles and the works cited by those articles.

Adverse Effects of the Ketogenic Diet

As with all medical therapies, the ketogenic diet is not without risk of adverse effects, which should be communicated at the outset of this article and with patients in the clinic. The only known absolute contraindications to a ketogenic diet are porphyria and pyruvate carboxylase deficiency secondary to underlying metabolic derangements.⁷ Certain metabolic cytopathies and carnitine deficiency are relative contraindications, and patients with these conditions should be cautiously placed on this diet and closely monitored. Dehydration, acidosis, lethargy, hypoglycemia, dyslipidemia, electrolyte imbalances, prurigo pigmentosa, and gastrointestinal distress may be an acute issue, but these effects are transient and can be managed. Chronic adverse effects are nephrolithiasis (there are recommended screening procedures for those at risk and prophylactic therapies, which is beyond the scope of this article) and weight loss.⁷

NLRP3 Inflammasome Suppression

Youm et al⁸ reported their findings in Nature Medicine that β-hydroxybutyrate, a ketone body that naturally circulates in the human body, specifically suppresses activity of the NLRP3 inflammasome. The NLRP3 inflammasome serves as the activating platform for IL-1β.⁸ Aberrant and elevated IL-1β levels cause or are associated with a number of dermatologic diseases—namely, the autoinflammatory syndromes (familial cold autoinflammatory syndrome, Muckle-Wells syndrome, neonatal-onset multisystemic disease/chronic infantile neurological cutaneous articular syndrome), hyperimmunoglobulinemia D with periodic fever syndrome, tumor necrosis factor–receptor associated periodic syndrome, juvenile idiopathic arthritis, relapsing polychondritis, Schnitzler syndrome, Sweet syndrome, Behçet disease, gout, sunburn and contact hypersensitivity, hidradenitis suppurativa, and metastatic melanoma.⁷ Clearly, the ketogenic diet may be employed in a therapeutic manner (though to what degree, we need further study) for these dermatologic conditions based on the interaction with the NRLP3 inflammasome and IL-1β.

Acne

A link between acne and diet has long been suspected, but a lack of well-controlled studies has caused only speculation to remain. Recent literature suggests that the effects of insulin may be a notable driver of acne through effects on sex hormones and subsequent effects on sebum production and inflammation. Cordain et al⁹ discuss the mechanism by which insulin can worsen acne in a valuable article, which Paoli et al¹⁰ later corroborated. Essentially, insulin propagates acne by 2 known mechanisms. First, an increase in serum insulin causes a rise in insulinlike growth factor 1 levels and a decrease in insulinlike growth factor binding protein 3 levels, which directly influences keratinocyte proliferation and reduces retinoic acid receptor/retinoid X receptor activity in the skin, causing hyperkeratinization and concomitant abnormal desquamation of the follicular epithelium.^9,10 Second, this increase in insulinlike growth factor 1 and insulin causes a decrease in sex hormone–binding globulin and leads to increased androgen production and circulation in the skin, which causes an increase in sebum production. These factors combined with skin that is colonized with Cutibacterium acnes lead to an inflammatory response and the disease known as acne vulgaris.^9,10 A ketogenic diet could help ameliorate acne because it results in very little insulin secretion, unlike the typical Western diet, which causes frequent large spikes in insulin levels. Furthermore, the anti-inflammatory effects of ketones would benefit the inflammatory nature of this disease.

DM and Diabetic Skin Disease

Diabetes mellitus carries with it the risk for skin diseases specific to the diabetic disease process, such as increased risk for bacterial and fungal infections, venous stasis, pruritus (secondary to poor circulation), acanthosis nigricans, diabetic dermopathy, necrobiosis lipoidica diabeticorum, digital sclerosis, and bullosis diabeticorum.¹¹ It is well established that better control of DM results in better disease state outcomes.¹² The ketogenic diet has shown itself to be a formidable and successful treatment in the diseases of carbohydrate intolerance (eg, metabolic syndrome, insulin resistance, type 2 DM) because of several known mechanisms, including less glucose entering the body and thus less fat deposition, end-product glycation, and free-radical production (discussed below); enhanced fat loss and metabolic efficiency; increased insulin sensitivity; and decreased inflammation.¹³ Lowering a patient’s insulin resistance through a ketogenic diet may help prevent or treat diabetic skin disease.

Dermatologic Malignancy

A ketogenic diet has been of interest in oncology research as an adjunctive therapy for several reasons: anti-inflammatory effects, antioxidation effects, possible effects on mammalian target of rapamycin (mTOR) regulation,⁷ and exploitation of the Warburg effect.¹⁴ One article discusses how mTOR, a cell-cycle regulator of particular importance in cancer biology, can be influenced by ketones both directly and indirectly through modulating the inflammatory response.⁷ It has been shown that suppressing mTOR activity limits and slows tumor growth and spread. Ketones also may prove to be a unique method of metabolically exploiting cancer physiology. The Warburg effect, which earned Otto Warburg the Nobel Prize in Physiology or Medicine in 1931, is the observation that cancerous cells produce adenosine triphosphate solely through aerobic glycolysis followed by lactic acid fermentation.¹⁴ This phenomenon is the basis of the positron emission tomography scan. There are several small studies of the effects of ketogenic diets on malignancy, and although none of these studies are of substantial size or control, they show that a ketogenic diet can halt or even reverse tumor growth.¹⁵ The hypothesis is that because cancer cells cannot metabolize ketones (but normal cells can), the Warburg effect can be taken advantage of through a ketogenic diet to aid in the treatment of malignant disease.¹⁴ If further studies find it a formidable treatment, it most certainly would be helpful for the dermatologist involved in the treatment of cutaneous cancers.

Oxidative Stress

Oxidative stress, a state brought about when reactive oxygen species (ROS) production exceeds the antioxidant capacity of the cell and causes damage, is known to be a central part of certain skin diseases (eg, acne, psoriasis, cutaneous malignancy, varicose ulcers, cutaneous allergic reactions, and drug-induced skin photosensitivity).⁷ There are 2 proven mechanisms by which a ketogenic diet can augment the body’s innate antioxidation capacity. First, ketones activate a potent antioxidant upregulating protein known as NRF2, which is bound in cytosol and remains inactive until activated by certain stimuli (ie, ketones).¹⁶ Migration to the nucleus causes transcriptional changes in DNA to upregulate, via a myriad of pathways, antioxidant production in the cell; most notably, it results in increased glutathione levels.¹⁷ NRF2 also targets several genes involved in chronic inflammatory skin diseases that cause an increase in the antioxidant capacity.¹⁸ As an aside, several foods encouraged on a ketogenic diet also activate NRF2 independently of ketones (eg, coffee, broccoli).¹⁹ Second, a ketogenic diet results in fewer produced ROS and an increase in the nicotinamide adenine dinucleotide ratio produced by the mitochondria; in short, it is a more efficient way of producing cellular energy while enhancing mitochondrial function. When fewer ROS are produced, there is less oxidative stress that needs to be attended to by the cell and less cellular damage. Feichtinger et al¹⁹ point out that mitochondrial inefficiency and dysfunction often are overlooked components in several skin diseases, and based on the studies discussed above, these diseases may be aided with a ketogenic diet.

Patient Applications

Clearly, a ketogenic diet is therapeutic, and there are many promising potential roles it may play in the treatment of a wide variety of health and disease states through hormonal normalization, antioxidant effects, anti-inflammatory effects, and improvement of metabolic risk factors. However, there are vast limitations to what is known about the ketogenic diet and how it might be employed, particularly by the dermatologist. First, the ketogenic diet lacks a firm definition. Although processed inflammatory vegetable oils and meats are low in carbohydrates and high in fat by definition, it is impossible to argue that they are healthy options for consumption and disease prevention and treatment. Second, nutrigenomics dictates that there must be an individual role in how the diet is employed (eg, patients who are lactose intolerant will need to stay away from dairy). Third, there are no clear proven clinical results from the ketogenic diet in the realm of dermatology. Fourth, as with everything, there are potential detrimental side effects of the ketogenic diet that must be considered for patients (though there are established screening procedures and prophylactic therapies that are beyond the scope of this article). Further, other diets have shown benefit for many other disease states and health promotion purposes (eg, the Mediterranean diet).²⁰ We do not know yet if the avoidance of certain dietary factors such as processed carbohydrates and fats are more beneficial than adopting a state of ketosis at this time, and therefore we are not claiming superiority of one dietary approach over others that are proven to promote health.

Because there are no large-scale studies of the ketogenic diet, there is no verified standardization of initiating and monitoring it, though certain academic centers do have published methods of doing so.²¹ There are ample anecdotal methods of initiating, maintaining, and monitoring the ketogenic diet.²² In short, drastic restriction of carbohydrate intake and increased fat consumption are the staples of initiating the diet. Medium-chain triglyceride oil supplementation, coffee consumption, intermittent fasting, and low-level aerobic activity also are thought to aid in transition to a ketogenic state. As a result, a dermatologist may recommend that patients interested in this option begin by focusing on fat, fiber, and protein consumption while greatly reducing the amount of carbohydrates in the diet. Morning walks or more intense workouts for fitter patients should be encouraged. Consumption of serum ketone–enhancing foods (eg, coffee, medium-chain triglyceride oil, coconut products) also should be encouraged. A popular beverage known as Bulletproof coffee also may be of interest.²³ A blood ketone meter can be used for biofeedback to reinforce these behaviors by aiming for proper β-hydroxybutyrate levels. Numerous companies and websites exist for supporting those patients wishing to pursue a ketogenic state, some hosted by physicians/researchers with others hosted by laypeople with an interest in the topic; discretion should be used as to the clinical and scientific accuracy of these sites. The dermatologist in particular can follow these patients and assess for changes in severity of skin disease, subjective well-being, need for medications and adjunctive therapies, and status of comorbid conditions.

For more information on the ketogenic diet, consider reading the works of the following physicians and researchers who all have been involved with or are currently conducting research in the medical use of ketones and ketogenic diets: David Perlmutter, MD; Thomas Seyfried, PhD; Dominic D’Agostino, PhD; Terry Wahls, MD; Jeff Volek, PhD; and Peter Attia, MD.

Conclusion

Based on the available data, there is potential for use of the ketogenic diet in an adjunctive manner for dermatologic applications, and studies should be undertaken to establish the efficacy or inefficacy of this diet as a preventive measure or treatment of skin disease. With the large push for complementary and alternative therapies over the last decade, particularly for skin disease, the time for research on the ketogenic diet is ripe. Over the coming years, it is our hope that larger clinical, randomized, controlled trials will be conducted for the benefit of dermatology patients worldwide.

The ketogenic diet has been therapeutically employed by physicians since the times of Hippocrates, primarily for its effect on the nervous system.¹ The neurologic literature is inundated with the uses of this medicinal diet for applications in the treatment of epilepsy, neurodegenerative disease, malignancy, and enzyme deficiencies, among others.² In recent years, physicians and scientists have moved to study the application of a ketogenic diet in the realms of cardiovascular disease,³ autoimmune disease,⁴ management of diabetes mellitus (DM) and obesity,^3,5 and enhancement of sports and combat performance,⁶ all with promising results. Increased interest in alternative therapies among the lay population and the efficacy purported by many adherents has spurred intrigue by health care professionals.

Fourth, as with everything, there are potential detrimental side effects of the ketogenic diet that must be considered for patients (though there are established screening procedures and prophylactic therapies that are beyond the scope of this article). Further, other diets have shown benefit for many other disease states and health promotion purposes (eg, the Mediterranean diet).²⁰ We do not know yet if the avoidance of certain dietary factors such as processed carbohydrates and fats are more beneficial than adopting a state of ketosis at this time, and therefore we are not claiming superiority of one dietary approach over others that are proven to promote health.

Because there are no large-scale studies of the ketogenic diet, there is no verified standardization of initiating and monitoring it, though certain academic centers do have published methods of doing so.²¹ There are ample anecdotal methods of initiating, maintaining, and monitoring the ketogenic diet.²² In short, drastic restriction of carbohydrate intake and increased fat consumption are the staples of initiating the diet. Medium-chain triglyceride oil supplementation, coffee consumption, intermittent fasting, and low-level aerobic activity also are thought to aid in transition to a ketogenic state. As a result, a dermatologist may recommend that patients interested in this option begin by focusing on fat, fiber, and protein consumption while greatly reducing the amount of carbohydrates in the diet. Morning walks or more intense workouts for fitter patients should be encouraged. Consumption of serum ketone–enhancing foods (eg, coffee, medium-chain triglyceride oil, coconut products) also should be encouraged. A popular beverage known as Bulletproof coffee also may be of interest.²³ A blood ketone meter can be used for biofeedback to reinforce these behaviors by aiming for proper β-hydroxybutyrate levels. Numerous companies and websites exist for supporting those patients wishing to pursue a ketogenic state, some hosted by physicians/researchers with others hosted by laypeople with an interest in the topic; discretion should be used as to the clinical and scientific accuracy of these sites. The dermatologist in particular can follow these patients and assess for changes in severity of skin disease, subjective well-being, need for medications and adjunctive therapies, and status of comorbid conditions.

For more information on the ketogenic diet, consider reading the works of the following physicians and researchers who all have been involved with or are currently conducting research in the medical use of ketones and ketogenic diets: David Perlmutter, MD; Thomas Seyfried, PhD; Dominic D’Agostino, PhD; Terry Wahls, MD; Jeff Volek, PhD; and Peter Attia, MD.

Conclusion

Based on the available data, there is potential for use of the ketogenic diet in an adjunctive manner for dermatologic applications, and studies should be undertaken to establish the efficacy or inefficacy of this diet as a preventive measure or treatment of skin disease. With the large push for complementary and alternative therapies over the last decade, particularly for skin disease, the time for research on the ketogenic diet is ripe. Over the coming years, it is our hope that larger clinical, randomized, controlled trials will be conducted for the benefit of dermatology patients worldwide.

Many Americans who are treated with prescription opioid analgesics would be better off with less opioid or none at all. To that end, published opioid prescribing guidelines do provide guidance on the mechanics of tapering patients off opioids^1-4—but they have a major flaw: They do not adequately account for the fact that people who have a diagnosis of chronic pain are a heterogeneous group and require diagnosis-specific treatment planning. A patient-centered approach to opioid tapers must account for the reality that many people who are given a prescription for an opioid to treat pain have significant mental health conditions—for which opioids act as a psychotropic agent. An opioid taper must therefore address psychological trauma, in particular.⁵ (See “Tapering and harm-reduction strategies have failed.”^6-14)

In this article, we present an evidence-based consensus approach to opioid tapering for your practice that is informed by a broader understanding of why patients take prescription opioids and why they, occasionally, switch to illicit drugs when their prescription is tapered. This consensus approach is based on the experience of the authors, members of the pain faculty of Project ECHO (Extension for Community Healthcare Outcomes) of the ECHO Institute, a worldwide initiative that uses adult learning techniques and interactive video technology to connect community providers with specialists at centers of excellence in regular real-time collaborative sessions. We are variously experts in pain medicine, primary care, psychology, addiction medicine, pharmacy, behavioral health therapy, occupational medicine, and Chinese medicine.

Why Americans obtain prescription opioids

There are 4 principal reasons why patients obtain prescription opioids, beyond indicated analgesic uses:

1. Patients seek the antianxiety and antidepressant effects of opioids. Multiple converging lines of evidence suggest that antianxiety and antidepressant effects of opioids are a significant reason that patients in the United States persist in requesting prescriptions for opioids:

• In our experience with more than 500 primary care telemedicine case presentations, at least 50% of patients say that the main effect of opioids prescribed for them is “it makes me feel calm” or “more relaxed.”
• In a 2007 survey of 91,823 US residents older than 18 years, nonmedical use of opioids was statistically associated with panic, social anxiety, and depressive symptoms.¹⁵
• Ten years later, Von Korff and colleagues found that more than half of opioid prescriptions written in the United States were for the small percentage of patients who have a diagnosis of serious anxiety or depression.¹³
• In 2016, Yovell and colleagues reported that ultra-low-dosage buprenorphine markedly reduced suicidal ideation over 4 weeks in 62 patients with varied levels of depression.¹⁶

There is also mechanistic evidence that the antianxiety and antidepressant effects of opioids are significant reasons Americans persist in requesting prescription opioids. The literature suggests that opioid receptors play a role in mood regulation, including alleviation of depression and anxiety; recent research suggests that oxycodone might be a unique mood-altering drug compared to other common prescription opioids because of its ability to affect mood through the δ opioid receptor.^17-20

It should not be a surprise that Americans often turn to opioids to address posttraumatic stress disorder (PTSD), anxiety, and depression. A recent study of the state of the US mental health system concluded that mental health services in the United States are inadequate—despite evidence that > 50% of Americans seek, or consider seeking, treatment for mental health problems for themselves or others.²¹

2. Patients experience pain unrelated to tissue damage. Rather, they are in pain “for psychological reasons.”²² In 2016, Davis and Vanderah wrote: “We theorize that a functional change in the [central nervous system] can occur in response to certain emotional states or traumatic experiences (eg, child abuse, assault, accidents).” They connect this change to central sensitization and a reduced pain-perception threshold,²³ and strongly suspect that many patients with chronic pain have undiagnosed and untreated psychological trauma that has changed the way their central nervous system processes sensory stimuli. The authors call this “trauma-induced hyperalgesia.”

Continue to: Psychological trauma...

Psychological trauma is uniquely capable of producing hyperalgesia, compared to anxiety or depression. In a study of veterans, Defrin and colleagues demonstrated hyperalgesia in patients who had a diagnosis of PTSD but not in controls group who had an anxiety disorder only.²⁴

High-dosage prescribing of opioids has fallen by 48% since 2011, yet the decline has not reduced overdose events of any kind.

To support successful opioid tapering, trauma-induced hyperalgesia, when present, must be addressed. Treatment of what the International Association for the Study of Pain calls “pain due to psychological factors”²² requires specific trauma therapy. However, our experience validates what researchers have to say about access to treatment of psychological trauma in the United States: “…[C]linical research has identified certain psychological interventions that effectively ameliorate the symptoms of PTSD. But most people struggling with PTSD don’t receive those treatments.”²⁵

We have no doubt that this is due, in part, to underdiagnosis of psychological trauma, even in mental health clinics. According to Miele and colleagues, “PTSD remains largely undiagnosed and undertreated in mental health outpatients, even in teaching hospitals, with diagnosis rates as low as 4% while published prevalence is between 7% and 50% in this population.”²⁶

3. Patients suffer from opioid use disorder (OUD) and complain of pain to obtain opioids by prescription. For patients with OUD, their use is out of control; they devote increasing mental and physical resources to obtaining, using, and recovering from substances; and they continue to use despite adverse consequences.²⁷ The prevalence of OUD in primary care clinics varies strikingly by the location of clinics. In Washington state, the prevalence of moderate and severe OUD in a large population of patients who had been prescribed opioids through primary care clinics was recently determined to be between 21.5% and 23.9%.¹³

4. Patients are obtaining opioid prescriptions for people other than themselves. While this is a reason that patients obtain opioid prescriptions, it is not necessarily common. Statistics show that the likelihood of a prescription being diverted intentionally is low: Dart and colleagues found that diversion has become uncommon in the general population.²⁸

Why we taper opioid analgesics

Reasons for an opioid taper include concern that the patient has, or will develop, an OUD; will experience accidental or intentional overdose; might be diverting opioids; is not benefiting from opioid therapy for pain; or is experiencing severe adverse effects. A patient who has nociceptive pain and might have ­opioid-induced hyperalgesia will require a much different opioid taper plan than a patient with untreated PTSD or a patient with severe OUD.

Misunderstanding can lead to inappropriate tapering

We often encounter primary care providers who believe that a large percentage of patients on chronic opioid therapy inevitably develop OUD. This is a common reason for initiating opioid taper. Most patients on a chronic opioid do become physically dependent, but only a small percentage of patients develop psychological dependence (ie, ­addiction or OUD).²⁹

Physical dependence is “a state of adaptation that is manifested by a drug class–­specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist.”³⁰ Symptoms of opioid withdrawal include muscle aches; abdominal cramping; increased lacrimation, rhinorrhea, and perspiration; diarrhea; agitation and anxiety; insomnia; and piloerection. Opioid withdrawal symptoms are caused by physical dependence, not by addiction. They can be mitigated by tapering slowly and instituting adjuvant medications, such as clonidine, to attenuate symptoms.

Psychological dependence, or addiction (that is, OUD, as described in the Diagnostic and Statistical Manual of Mental Disorders 5th edition²⁷), comprises primarily 3 behavioral criteria:

• Loss of control of the medication, with compulsive use
• Continued use despite adverse consequences of using opioids, such as arrest for driving under the influence and deterioration of social, family, or work performance
• Obsession or preoccupation with obtaining and using the substance. In properly selected chronic opioid therapy patients, there is evidence that new-onset OUD is not as common as has been thought. A recent study of the risk for opioid addiction after use of an opioid for ≥ 90 days for chronic noncancer pain found that the absolute rate of de novo OUD among patients treated for 90 days was 0.72%.²⁹ A systematic review by Fishbain and colleagues of 24 studies of opioid-exposed patients found a risk of 3.27% overall—0.19% for patients who did not have a history of abuse or addiction.³¹ As Director of the National Institute on Drug Abuse Norma Volkow, MD, wrote in 2016: “Addiction occurs in only a small percentage of people who are exposed to opioids—even among those with preexisting vulnerabilities.”³²

Assessment should focus on why the patient is taking an opioid

A strong case can be made that less opioid is better for many of the people for whom these medications are prescribed for chronic noncancer pain. However, a one-size-fits-all dosage reduction and addiction-focused ­approach to opioid tapering has not worked: The assessment and treatment paradigm must change, in our view.

Continue to: During assessment...

During assessment, we must adopt the means to identify the reason that a patient is using a prescription opioid. It is of particular importance that we identify patients using opioids for their psychotropic properties, particularly when the goal is to cope with the effects of psychological trauma. The subsequent treatment protocol will then need to include time for effective, evidence-based behavioral health treatment of anxiety, PTSD, or depression. If opioids are serving primarily as psychotropic medication, an attempt to taper before establishing effective behavioral health treatment might lead the patient to pursue illegal means of procuring opioid medication.

Antianxiety and antidepressant effects of opioids are a significant reason that patients persist in requesting prescriptions.

We acknowledge that primary care physicians are not reimbursed for trauma screening and that evidence-based intensive trauma treatment is generally unavailable in the United States. Both of these shortcomings must be corrected if we want to stem the opioid crisis.

If diversion is suspected and there is evidence that the patient is not currently taking prescribed opioids (eg, a negative urine drug screen), discontinuing the opioid prescription is the immediate next step for the sake of public safety.

Considering a taper? Take this 5-step approach

Once it appears that tapering an opioid is indicated, we propose that you take the following steps:

• Establish whether it is safe to continue prescribing (follow the route provided in “2 decisions to make before continuing to prescribe an opioid for chronic noncancer pain”); if continuing it is not safe, take steps to protect the patient and the community
• Determine whether assessment by a trauma-informed behavioral health expert is needed, assuming that, in your judgment, it is safe to continue the opioid (TABLE³³). When behavioral health assessment is needed, you need 3 questions answered by that assessment: (1) Are psychological factors present that might put the patient at risk during an opioid taper? (2) What are those factors? (3) What needs to done about them before the taper is started? Recalling that psychological trauma often is not assessed by behavioral health colleagues, it is necessary to provide the behavioral health provider with a specific request to assess trauma burden, and state the physical diagnoses that are causing pain or provide a clear statement that no such diagnoses can be made. (See the FIGURE, which we developed in conjunction with behavioral health colleagues to help the consultant understand what the primary care physician needs from a behavioral health assessment.)
• Obtain consultation from a physical therapist, pain medicine specialist, and, if possible, an alternative or complementary medicine provider to determine what nonpharmacotherapeutic modalities can be instituted to treat pain before tapering the opioid.
• Initiate the Screening, Brief Intervention and Referral to Treatment (SBIRT) approach if OUD is suspected (www.samhsa.gov/sbirt).³⁴ This motivational interviewing tool identifies patients with a substance use disorder, severity of use, and appropriate level of treatment. (If OUD is suspected during assessment, next steps are to stop prescribing and implement harm-reduction strategies, such as primary care level medically assisted treatment [MAT] with buprenorphine, followed by expert behavioral health-centered addiction treatment.)
• Experiment with dosage reduction according to published guidance, if (1) psychological factors are absent or have been adequately addressed, according to the behavioral health consultant, and (2) nonpharmacotherapeutic strategies are in place.^8-11

Shifting to a patient-centered approach

The timing and choice of opioid tapers, in relation to harm reduction and intervention targeting the root cause of a patient’s complaint of pain, have not been adequately explored. In our practice, we’ve shifted from an addiction-centered, dosage-centered approach to opioid taper to a patient-centered approach³⁵ that emphasizes behavioral-medical integration—an approach that we broadly endorse. Such an approach (1) is based on a clear understanding of why the patient is taking opioid pain medication, (2) engages medical and complementary or alternative medicine specialists, (3) addresses underdiagnosis of psychological trauma, and (4) requires a quantum leap in access to trauma-specific behavioral health treatment resources. ³⁶

Continue to: To underscore the case...

To underscore the case for shifting to a patient-centered approach³⁵ we present sample cases in “How a patient-centered approach to tapering opioids looks in practice.”

An eye toward the future. To inform future approaches to opioid tapering, more resources need to be deployed to

• support screening and risk stratification for PTSD, anxiety, and related disorders at the primary care level,
• continue the effort to identify and treat OUD,
• develop best-practice responses to screening, and
• make harm-reduction strategies that are now reserved for patients with OUD available to those who don't have OUD.

We urge that research be pursued into best practices for chronic pain interventions that target psychological trauma, anxiety, and depression.

According to Miele and colleagues, “PTSD remains largely undiagnosed and undertreated in mental health outpatients, even in teaching hospitals, with diagnosis rates as low as 4% while published prevalence is between 7% and 50% in this population.”²⁶

3. Patients suffer from opioid use disorder (OUD) and complain of pain to obtain opioids by prescription. For patients with OUD, their use is out of control; they devote increasing mental and physical resources to obtaining, using, and recovering from substances; and they continue to use despite adverse consequences.²⁷ The prevalence of OUD in primary care clinics varies strikingly by the location of clinics. In Washington state, the prevalence of moderate and severe OUD in a large population of patients who had been prescribed opioids through primary care clinics was recently determined to be between 21.5% and 23.9%.¹³

4. Patients are obtaining opioid prescriptions for people other than themselves. While this is a reason that patients obtain opioid prescriptions, it is not necessarily common. Statistics show that the likelihood of a prescription being diverted intentionally is low: Dart and colleagues found that diversion has become uncommon in the general population.²⁸

Why we taper opioid analgesics

Reasons for an opioid taper include concern that the patient has, or will develop, an OUD; will experience accidental or intentional overdose; might be diverting opioids; is not benefiting from opioid therapy for pain; or is experiencing severe adverse effects. A patient who has nociceptive pain and might have ­opioid-induced hyperalgesia will require a much different opioid taper plan than a patient with untreated PTSD or a patient with severe OUD.

Misunderstanding can lead to inappropriate tapering

We often encounter primary care providers who believe that a large percentage of patients on chronic opioid therapy inevitably develop OUD. This is a common reason for initiating opioid taper. Most patients on a chronic opioid do become physically dependent, but only a small percentage of patients develop psychological dependence (ie, ­addiction or OUD).²⁹

Physical dependence is “a state of adaptation that is manifested by a drug class–­specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist.”³⁰ Symptoms of opioid withdrawal include muscle aches; abdominal cramping; increased lacrimation, rhinorrhea, and perspiration; diarrhea; agitation and anxiety; insomnia; and piloerection. Opioid withdrawal symptoms are caused by physical dependence, not by addiction. They can be mitigated by tapering slowly and instituting adjuvant medications, such as clonidine, to attenuate symptoms.

Psychological dependence, or addiction (that is, OUD, as described in the Diagnostic and Statistical Manual of Mental Disorders 5th edition²⁷), comprises primarily 3 behavioral criteria:

• Loss of control of the medication, with compulsive use
• Continued use despite adverse consequences of using opioids, such as arrest for driving under the influence and deterioration of social, family, or work performance
• Obsession or preoccupation with obtaining and using the substance. In properly selected chronic opioid therapy patients, there is evidence that new-onset OUD is not as common as has been thought. A recent study of the risk for opioid addiction after use of an opioid for ≥ 90 days for chronic noncancer pain found that the absolute rate of de novo OUD among patients treated for 90 days was 0.72%.²⁹ A systematic review by Fishbain and colleagues of 24 studies of opioid-exposed patients found a risk of 3.27% overall—0.19% for patients who did not have a history of abuse or addiction.³¹ As Director of the National Institute on Drug Abuse Norma Volkow, MD, wrote in 2016: “Addiction occurs in only a small percentage of people who are exposed to opioids—even among those with preexisting vulnerabilities.”³²

Assessment should focus on why the patient is taking an opioid

A strong case can be made that less opioid is better for many of the people for whom these medications are prescribed for chronic noncancer pain. However, a one-size-fits-all dosage reduction and addiction-focused ­approach to opioid tapering has not worked: The assessment and treatment paradigm must change, in our view.

Continue to: During assessment...

During assessment, we must adopt the means to identify the reason that a patient is using a prescription opioid. It is of particular importance that we identify patients using opioids for their psychotropic properties, particularly when the goal is to cope with the effects of psychological trauma. The subsequent treatment protocol will then need to include time for effective, evidence-based behavioral health treatment of anxiety, PTSD, or depression. If opioids are serving primarily as psychotropic medication, an attempt to taper before establishing effective behavioral health treatment might lead the patient to pursue illegal means of procuring opioid medication.

Antianxiety and antidepressant effects of opioids are a significant reason that patients persist in requesting prescriptions.

We acknowledge that primary care physicians are not reimbursed for trauma screening and that evidence-based intensive trauma treatment is generally unavailable in the United States. Both of these shortcomings must be corrected if we want to stem the opioid crisis.

If diversion is suspected and there is evidence that the patient is not currently taking prescribed opioids (eg, a negative urine drug screen), discontinuing the opioid prescription is the immediate next step for the sake of public safety.

Considering a taper? Take this 5-step approach

Once it appears that tapering an opioid is indicated, we propose that you take the following steps:

• Establish whether it is safe to continue prescribing (follow the route provided in “2 decisions to make before continuing to prescribe an opioid for chronic noncancer pain”); if continuing it is not safe, take steps to protect the patient and the community
• Determine whether assessment by a trauma-informed behavioral health expert is needed, assuming that, in your judgment, it is safe to continue the opioid (TABLE³³). When behavioral health assessment is needed, you need 3 questions answered by that assessment: (1) Are psychological factors present that might put the patient at risk during an opioid taper? (2) What are those factors? (3) What needs to done about them before the taper is started? Recalling that psychological trauma often is not assessed by behavioral health colleagues, it is necessary to provide the behavioral health provider with a specific request to assess trauma burden, and state the physical diagnoses that are causing pain or provide a clear statement that no such diagnoses can be made. (See the FIGURE, which we developed in conjunction with behavioral health colleagues to help the consultant understand what the primary care physician needs from a behavioral health assessment.)
• Obtain consultation from a physical therapist, pain medicine specialist, and, if possible, an alternative or complementary medicine provider to determine what nonpharmacotherapeutic modalities can be instituted to treat pain before tapering the opioid.
• Initiate the Screening, Brief Intervention and Referral to Treatment (SBIRT) approach if OUD is suspected (www.samhsa.gov/sbirt).³⁴ This motivational interviewing tool identifies patients with a substance use disorder, severity of use, and appropriate level of treatment. (If OUD is suspected during assessment, next steps are to stop prescribing and implement harm-reduction strategies, such as primary care level medically assisted treatment [MAT] with buprenorphine, followed by expert behavioral health-centered addiction treatment.)
• Experiment with dosage reduction according to published guidance, if (1) psychological factors are absent or have been adequately addressed, according to the behavioral health consultant, and (2) nonpharmacotherapeutic strategies are in place.^8-11

Shifting to a patient-centered approach

The timing and choice of opioid tapers, in relation to harm reduction and intervention targeting the root cause of a patient’s complaint of pain, have not been adequately explored. In our practice, we’ve shifted from an addiction-centered, dosage-centered approach to opioid taper to a patient-centered approach³⁵ that emphasizes behavioral-medical integration—an approach that we broadly endorse. Such an approach (1) is based on a clear understanding of why the patient is taking opioid pain medication, (2) engages medical and complementary or alternative medicine specialists, (3) addresses underdiagnosis of psychological trauma, and (4) requires a quantum leap in access to trauma-specific behavioral health treatment resources. ³⁶

Continue to: To underscore the case...

To underscore the case for shifting to a patient-centered approach³⁵ we present sample cases in “How a patient-centered approach to tapering opioids looks in practice.”

An eye toward the future. To inform future approaches to opioid tapering, more resources need to be deployed to

• support screening and risk stratification for PTSD, anxiety, and related disorders at the primary care level,
• continue the effort to identify and treat OUD,
• develop best-practice responses to screening, and
• make harm-reduction strategies that are now reserved for patients with OUD available to those who don't have OUD.

We urge that research be pursued into best practices for chronic pain interventions that target psychological trauma, anxiety, and depression.

Psoriasis is a chronic inflammatory skin disorder that affects patients’ quality of life and social interactions.¹ Several studies have shown a strong consistent association between psoriasis and depression as well as possible suicidal ideation and behavior (SIB).^1-13 Notable findings from a 2018 review found depression prevalence ranged from 2.1% to 33.7% among patients with psoriasis vs 0% to 22.7% among unaffected patients.⁷ In a 2017 meta-analysis, Singh et al² found increased odds of SIB (odds ratio [OR], 2.05), attempted suicide (OR, 1.32), and completed suicide (OR, 1.20) in patients with psoriasis compared to those without psoriasis. In 2018, Wu and colleagues⁷ reported that odds of SIB among patients with psoriasis ranged from 1.01 to 1.94 times those of patients without psoriasis, and SIB and suicide attempts were more common than in patients with other dermatologic conditions. Koo and colleagues¹ reached similar conclusions. At the same time, the occurrence of attempted and completed suicides among patients in psoriasis clinical trials has raised concerns about whether psoriasis medications also may increase the risk for SIB.⁷

We review research on the effects of psoriasis treatment on patients’ symptoms of depression and SIB, with a focus on recent analyses of depressive symptoms and SIB among patients with psoriasis who received brodalumab in clinical trials. Finally, we suggest approaches clinicians may consider when caring for patients with psoriasis who may be at risk for depression and SIB.

MATERIALS AND METHODS

We reviewed research on the effects of biologic therapy for psoriasis on depression and SIB, with a primary focus on recent large meta-analyses. Published findings on the pattern of SIB in brodalumab clinical trials and effects of brodalumab treatment on symptoms of depression and anxiety are summarized. The most recent evidence (January 2014–December 2018) regarding the mental health comorbidities of psoriasis was assessed using published English-language research data and review articles according to a PubMed search of articles indexed for MEDLINE using the following terms: depression, anxiety, suicide, suicidal ideation and behavior, SIB, brodalumab, or psoriasis. We also reviewed citations within articles to identify relevant sources. Implications for clinical care of patients with psoriasis are discussed based on expert recommendations and the authors’ clinical experience.

RESULTS

Effects of Psoriasis Treatment on Symptoms of Depression and Suicidality

Occurrences of attempted suicide and completed suicide have been reported during treatment with several psoriasis medications,^7,9 raising concerns about whether these medications increase the risk for depression and SIB in an already vulnerable population. Wu and colleagues⁷ reviewed 11 studies published from 2006 to 2017 reporting the effects of medications for the treatment of psoriasis—adalimumab, apremilast, brodalumab, etanercept, and ustekinumab—on measures of depression and anxiety such as the Beck Depression Inventory, the Hospital Anxiety and Depression Scale (HADS), and the Patient Health Questionnaire (PHQ) 8. In each of the 11 studies, symptoms of depression improved after treatment, over time, or compared to placebo. Notably, the magnitude of improvement in symptoms of depression was not strongly linked to the magnitude of clinical improvement.⁷ Other recent studies have reported reductions in symptoms of depression with biologic therapies, including adalimumab, etanercept, guselkumab, ixekizumab, secukinumab, and ustekinumab.^14-21

With respect to suicidality, an analysis of publicly available data found low rates of completed and attempted suicides (point estimates of 0.0–0.15 per 100 patient-years) in clinical development programs of apremilast, brodalumab, ixekizumab, and secukinumab. Patient suicidality in these trials often occurred in the context of risk factors or stressors such as work, financial difficulties, depression, and substance abuse.⁷ In a detailed 2016 analysis of suicidal behaviors during clinical trials of apremilast, brodalumab, etanercept, infliximab, ixekizumab, secukinumab, tofacitinib, ustekinumab, and other investigational agents, Gooderham and colleagues⁹ concluded that the behaviors may have resulted from the disease or patients’ psychosocial status rather than from treatment and that treatment with biologics does not increase the risk for SIB. Improvements in symptoms of depression during treatment suggest the potential to improve patients’ psychiatric outcomes with biologic treatment.⁹

Evidence From Brodalumab Studies

Intensive efforts have been made to assess the effect of brodalumab, a fully human anti–IL-17RA monoclonal antibody shown to be efficacious in the treatment of moderate to severe plaque psoriasis, on symptoms of depression and to understand the incidence of SIB among patients receiving brodalumab in clinical trials.^22-27

Depression and Anxiety in Studies of Brodalumab
To examine the effects of brodalumab on symptoms of depression, the HADS questionnaire²⁸ was administered to patients in 1 of 3 phase 3 clinical trials of brodalumab.²³ A HADS score of 0 to 7 is considered normal, 8 to 10 is mild, 11 to 14 is moderate, and 15 to 21 is severe.²³ The HADS questionnaire was administered to evaluate the presence and severity of depression and anxiety symptoms at baseline and at weeks 12, 24, 36, and 52.²⁵ This scale was not used in the other 2 phase 3 studies of brodalumab because at the time those studies were initiated, there was no indication to include mental health screenings as part of the study protocol.

Patients were initially randomized to placebo (n=220), brodalumab 140 mg every 2 weeks (Q2W; n=219), or brodalumab 210 mg Q2W (the eventual approved dose; n=222) for 12 weeks.²³ At week 12, patients initially randomized to placebo were switched to brodalumab through week 52. Patients initially randomized to brodalumab 210 mg Q2W were re-randomized to either placebo or brodalumab 210 mg Q2W.²³ Depression and anxiety were common at baseline. Based on HADS scores, depression occurred among 27% and 26% of patients randomized to brodalumab and placebo, respectively; anxiety occurred in 36% of patients in each group.²² Among patients receiving brodalumab 210 mg Q2W from baseline to week 12, HADS depression scores improved in 67% of patients and worsened in 19%. In contrast, the proportion of patients receiving placebo whose depression scores improved (45%) was similar to the proportion whose scores worsened (38%). Hospital Anxiety and Depression Scale anxiety scores also improved more often with brodalumab than with placebo.²²

Furthermore, among patients who had moderate or severe depression or anxiety at baseline, a greater percentage experienced improvement with brodalumab than placebo.²³ Among 30 patients with moderate to severe HADS depression scores at baseline who were treated with brodalumab 210 mg Q2W, 22 (73%) improved by at least 1 depression category by week 12; in the placebo group, 10 of 22 (45%) improved. Among patients with moderate or severe anxiety scores, 28 of 42 patients (67%) treated with brodalumab 210 mg Q2W improved by at least 1 anxiety category compared to 8 of 27 (30%) placebo-treated patients.²³

Over 52 weeks, HADS depression and anxiety scores continued to show a pattern of improvement among patients receiving brodalumab vs placebo.²⁵ Among patients initially receiving placebo, mean HADS depression scores were unchanged from baseline (5.3) to week 12 (5.5). After patients were switched to brodalumab 210 mg Q2W, there was a trend toward improvement between week 12 (5.4) and week 52 (3.1). Among patients initially treated with brodalumab 210 mg Q2W, mean depression scores fell from baseline (5.5) to week 12 (3.4), then rose again between weeks 12 (2.9) and 52 (3.5) in patients switched to placebo (Figure, A). The pattern of findings was similar for HADS anxiety scores (Figure, B).²⁵ Overall, brodalumab treatment appears to improve symptoms of depression and anxiety in patients being treated for psoriasis. This finding is consistent with the effects reported for other biologic therapies previously discussed.

SIB in Studies of Brodalumab
In addition to assessing the effect of brodalumab treatment on symptoms of depression and anxiety in patients with psoriasis, the brodalumab clinical trial program also tracked patterns of SIB among enrolled patients. In contrast with other clinical trials in which patients with a history of psychiatric disorders or substance abuse were excluded, clinical trials of brodalumab did not exclude patients with psychiatric disorders (eg, SIB, depression) and were therefore reflective of the real-world population of patients with moderate to severe psoriasis.²²

In a recently published, detailed analysis of psychiatric adverse events (AEs) in the brodalumab clinical trials, data related to SIB in patients with moderate to severe psoriasis were analyzed from the placebo-controlled phases and open-label, long-term extensions of a placebo-controlled phase 2 clinical trial and from the previously mentioned 3 phase 3 clinical trials.²² From the initiation of the clinical trial program, AEs were monitored during all trials. In response to completed suicides during some studies, additional SIB evaluations were later added at the request of the US Food and Drug Administration, including the Columbia Suicide Severity Rating Scale, the PHQ-8, and the Columbia Classification Algorithm for Suicide Assessment, to independently adjudicate SIB events.²²

In total, 4464 patients in the brodalumab clinical trials received at least 1 dose of brodalumab, and 4126 of these patients received at least 1 dose of brodalumab 210 mg Q2W.²² Total exposure was 9174 patient-years of brodalumab, and mean exposure was 23 months. During the 52-week controlled phases of the clinical trials, 7 patients receiving brodalumab experienced any form of SIB event, representing a time-adjusted incidence rate of 0.20 events (95% confidence interval [CI], 0.08-0.41 events) per 100 patient-years of exposure. During the same 52-week period, patients receiving the comparator drug ustekinumab had an SIB rate of 0.60 events (95% CI, 0.12-1.74 events) per 100 patient-years, which was numerically higher than the rate with brodalumab. Inferential statistical analyses were not performed, but overlapping 95% CIs around these point estimates imply a similar level of SIB risk associated with each agent in these studies. During controlled and uncontrolled treatment periods in all studies, the SIB rate among brodalumab-treated patients was 0.37 events per 100 patient-years.²²

Over all study phases, 3 completed suicides and 1 case adjudicated as indeterminate by the Columbia Classification Algorithm for Suicide Assessment review board were reported.²² All occurred in men aged 39 to 59 years. Of 6 patients with an AE of suicide attempt, all patients had at least 1 SIB risk factor and 3 had a history of SIB. The rate of SIB events was greater in patients with a history of depression (1.42) or suicidality (3.21) compared to those without any history of depression or suicidality (0.21 and 0.20, respectively).²² An examination of the regions in which the brodalumab studies were conducted showed generally consistent SIB incidence rates: 0.52, 0.29, 0.77, and 0 events per 100 patient-years in North America, Europe, Australia, and Russia, respectively.²⁴

As previously described, depression and other risk factors for SIB are prevalent among patients with psoriasis. In addition, the rate of suicide mortality has increased substantially over the last decade in the general population, particularly among middle-aged white men,²⁹ who made up much of the brodalumab clinical trial population.²² Therefore, even without treatment, it would not be surprising that SIB events occurred during the brodalumab trials. Most patients with SIB events during the trials had a history of predisposing risk factors.²² Prescribing information for brodalumab in the United States includes a boxed warning advising physicians to be aware of the risk of SIB as well as a statement that a causal relationship between SIB and brodalumab treatment has not been established.²⁷

COMMENT

This review indicates that depression is increased among patients with psoriasis regardless of treatment regimen⁷; however, the association between psoriasis and suicidality is unclear. In clinical trials of brodalumab, treatment resulted in improved symptoms of depression and anxiety among patients with psoriasis and was associated with lower rates of SIB compared to ustekinumab.^22,23

Despite the boxed warning in the brodalumab package insert concerning suicidality, a causal relationship between brodalumab treatment and increased risk of SIB has not been firmly established.²⁷ The US boxed warning is based on 3 completed suicides and 1 case adjudicated as indeterminate among more than 4000 patients who received at least 1 dose of brodalumab during global clinical trials (0.07% [3/4464]). Compliance in the Risk Evaluation and Mitigation Strategy (REMS) program is mandatory, and patient screening and counseling should not be minimized.²⁷ The 3 completed suicides occurred in patients who reported a history of financial stressors, legal difficulties, or depression and anxiety, and they occurred at least 140 days after initiation of treatment with brodalumab, a chronology that does not support a strong association between brodalumab exposure and SIB.²² Taking into consideration the increased risk for depression among individuals with psoriasis and the details surrounding the 3 completed suicides, an evidence-based causal relationship between brodalumab and increased risk for suicidality cannot be concluded. However, physicians must assess risks and benefits of any therapy in the context of the individual patient’s preferences, risk factors, and response to treatment.

Dermatologists who are aware of the comorbidity between psoriasis and mood disorders play an important role in evaluating patients with psoriasis for psychiatric risk factors.^30-32 The dermatologist should discuss with patients the relationship between psoriasis and depression, assess for any history of depression and SIB, and evaluate for signs and symptoms of depression and current SIB.³³ Screening tools, including the HADS or the short, easily administered PHQ-2³⁴ or PHQ-4,³⁵ can be used to assess whether patients have symptoms of depression.^1,36,37 Patients at risk for depression or SIB should be referred to their primary care physician or a mental health care practitioner.³⁷ Currently, there is a gap in knowledge in screening patients for psychiatric issues within the dermatology community^33,38; however, health care providers can give support to help bridge this gap.

Effects of Psoriasis Treatment on Symptoms of Depression and Suicidality

Occurrences of attempted suicide and completed suicide have been reported during treatment with several psoriasis medications,^7,9 raising concerns about whether these medications increase the risk for depression and SIB in an already vulnerable population. Wu and colleagues⁷ reviewed 11 studies published from 2006 to 2017 reporting the effects of medications for the treatment of psoriasis—adalimumab, apremilast, brodalumab, etanercept, and ustekinumab—on measures of depression and anxiety such as the Beck Depression Inventory, the Hospital Anxiety and Depression Scale (HADS), and the Patient Health Questionnaire (PHQ) 8.

Improvements in symptoms of depression during treatment suggest the potential to improve patients’ psychiatric outcomes with biologic treatment.⁹

Evidence From Brodalumab Studies

Intensive efforts have been made to assess the effect of brodalumab, a fully human anti–IL-17RA monoclonal antibody shown to be efficacious in the treatment of moderate to severe plaque psoriasis, on symptoms of depression and to understand the incidence of SIB among patients receiving brodalumab in clinical trials.^22-27

Depression and Anxiety in Studies of Brodalumab
To examine the effects of brodalumab on symptoms of depression, the HADS questionnaire²⁸ was administered to patients in 1 of 3 phase 3 clinical trials of brodalumab.²³ A HADS score of 0 to 7 is considered normal, 8 to 10 is mild, 11 to 14 is moderate, and 15 to 21 is severe.²³ The HADS questionnaire was administered to evaluate the presence and severity of depression and anxiety symptoms at baseline and at weeks 12, 24, 36, and 52.²⁵ This scale was not used in the other 2 phase 3 studies of brodalumab because at the time those studies were initiated, there was no indication to include mental health screenings as part of the study protocol.

Patients were initially randomized to placebo (n=220), brodalumab 140 mg every 2 weeks (Q2W; n=219), or brodalumab 210 mg Q2W (the eventual approved dose; n=222) for 12 weeks.²³ At week 12, patients initially randomized to placebo were switched to brodalumab through week 52. Patients initially randomized to brodalumab 210 mg Q2W were re-randomized to either placebo or brodalumab 210 mg Q2W.²³ Depression and anxiety were common at baseline. Based on HADS scores, depression occurred among 27% and 26% of patients randomized to brodalumab and placebo, respectively; anxiety occurred in 36% of patients in each group.²² Among patients receiving brodalumab 210 mg Q2W from baseline to week 12, HADS depression scores improved in 67% of patients and worsened in 19%. In contrast, the proportion of patients receiving placebo whose depression scores improved (45%) was similar to the proportion whose scores worsened (38%). Hospital Anxiety and Depression Scale anxiety scores also improved more often with brodalumab than with placebo.²²

Furthermore, among patients who had moderate or severe depression or anxiety at baseline, a greater percentage experienced improvement with brodalumab than placebo.²³ Among 30 patients with moderate to severe HADS depression scores at baseline who were treated with brodalumab 210 mg Q2W, 22 (73%) improved by at least 1 depression category by week 12; in the placebo group, 10 of 22 (45%) improved. Among patients with moderate or severe anxiety scores, 28 of 42 patients (67%) treated with brodalumab 210 mg Q2W improved by at least 1 anxiety category compared to 8 of 27 (30%) placebo-treated patients.²³

Over 52 weeks, HADS depression and anxiety scores continued to show a pattern of improvement among patients receiving brodalumab vs placebo.²⁵ Among patients initially receiving placebo, mean HADS depression scores were unchanged from baseline (5.3) to week 12 (5.5). After patients were switched to brodalumab 210 mg Q2W, there was a trend toward improvement between week 12 (5.4) and week 52 (3.1). Among patients initially treated with brodalumab 210 mg Q2W, mean depression scores fell from baseline (5.5) to week 12 (3.4), then rose again between weeks 12 (2.9) and 52 (3.5) in patients switched to placebo (Figure, A). The pattern of findings was similar for HADS anxiety scores (Figure, B).²⁵ Overall, brodalumab treatment appears to improve symptoms of depression and anxiety in patients being treated for psoriasis. This finding is consistent with the effects reported for other biologic therapies previously discussed.

SIB in Studies of Brodalumab
In addition to assessing the effect of brodalumab treatment on symptoms of depression and anxiety in patients with psoriasis, the brodalumab clinical trial program also tracked patterns of SIB among enrolled patients. In contrast with other clinical trials in which patients with a history of psychiatric disorders or substance abuse were excluded, clinical trials of brodalumab did not exclude patients with psychiatric disorders (eg, SIB, depression) and were therefore reflective of the real-world population of patients with moderate to severe psoriasis.²²

In a recently published, detailed analysis of psychiatric adverse events (AEs) in the brodalumab clinical trials, data related to SIB in patients with moderate to severe psoriasis were analyzed from the placebo-controlled phases and open-label, long-term extensions of a placebo-controlled phase 2 clinical trial and from the previously mentioned 3 phase 3 clinical trials.²² From the initiation of the clinical trial program, AEs were monitored during all trials. In response to completed suicides during some studies, additional SIB evaluations were later added at the request of the US Food and Drug Administration, including the Columbia Suicide Severity Rating Scale, the PHQ-8, and the Columbia Classification Algorithm for Suicide Assessment, to independently adjudicate SIB events.²²

In total, 4464 patients in the brodalumab clinical trials received at least 1 dose of brodalumab, and 4126 of these patients received at least 1 dose of brodalumab 210 mg Q2W.²² Total exposure was 9174 patient-years of brodalumab, and mean exposure was 23 months. During the 52-week controlled phases of the clinical trials, 7 patients receiving brodalumab experienced any form of SIB event, representing a time-adjusted incidence rate of 0.20 events (95% confidence interval [CI], 0.08-0.41 events) per 100 patient-years of exposure. During the same 52-week period, patients receiving the comparator drug ustekinumab had an SIB rate of 0.60 events (95% CI, 0.12-1.74 events) per 100 patient-years, which was numerically higher than the rate with brodalumab. Inferential statistical analyses were not performed, but overlapping 95% CIs around these point estimates imply a similar level of SIB risk associated with each agent in these studies. During controlled and uncontrolled treatment periods in all studies, the SIB rate among brodalumab-treated patients was 0.37 events per 100 patient-years.²²

Over all study phases, 3 completed suicides and 1 case adjudicated as indeterminate by the Columbia Classification Algorithm for Suicide Assessment review board were reported.²² All occurred in men aged 39 to 59 years. Of 6 patients with an AE of suicide attempt, all patients had at least 1 SIB risk factor and 3 had a history of SIB. The rate of SIB events was greater in patients with a history of depression (1.42) or suicidality (3.21) compared to those without any history of depression or suicidality (0.21 and 0.20, respectively).²² An examination of the regions in which the brodalumab studies were conducted showed generally consistent SIB incidence rates: 0.52, 0.29, 0.77, and 0 events per 100 patient-years in North America, Europe, Australia, and Russia, respectively.²⁴

As previously described, depression and other risk factors for SIB are prevalent among patients with psoriasis. In addition, the rate of suicide mortality has increased substantially over the last decade in the general population, particularly among middle-aged white men,²⁹ who made up much of the brodalumab clinical trial population.²² Therefore, even without treatment, it would not be surprising that SIB events occurred during the brodalumab trials. Most patients with SIB events during the trials had a history of predisposing risk factors.²² Prescribing information for brodalumab in the United States includes a boxed warning advising physicians to be aware of the risk of SIB as well as a statement that a causal relationship between SIB and brodalumab treatment has not been established.²⁷

COMMENT

This review indicates that depression is increased among patients with psoriasis regardless of treatment regimen⁷; however, the association between psoriasis and suicidality is unclear. In clinical trials of brodalumab, treatment resulted in improved symptoms of depression and anxiety among patients with psoriasis and was associated with lower rates of SIB compared to ustekinumab.^22,23

Despite the boxed warning in the brodalumab package insert concerning suicidality, a causal relationship between brodalumab treatment and increased risk of SIB has not been firmly established.²⁷ The US boxed warning is based on 3 completed suicides and 1 case adjudicated as indeterminate among more than 4000 patients who received at least 1 dose of brodalumab during global clinical trials (0.07% [3/4464]). Compliance in the Risk Evaluation and Mitigation Strategy (REMS) program is mandatory, and patient screening and counseling should not be minimized.²⁷ The 3 completed suicides occurred in patients who reported a history of financial stressors, legal difficulties, or depression and anxiety, and they occurred at least 140 days after initiation of treatment with brodalumab, a chronology that does not support a strong association between brodalumab exposure and SIB.²² Taking into consideration the increased risk for depression among individuals with psoriasis and the details surrounding the 3 completed suicides, an evidence-based causal relationship between brodalumab and increased risk for suicidality cannot be concluded. However, physicians must assess risks and benefits of any therapy in the context of the individual patient’s preferences, risk factors, and response to treatment.

Dermatologists who are aware of the comorbidity between psoriasis and mood disorders play an important role in evaluating patients with psoriasis for psychiatric risk factors.^30-32 The dermatologist should discuss with patients the relationship between psoriasis and depression, assess for any history of depression and SIB, and evaluate for signs and symptoms of depression and current SIB.³³ Screening tools, including the HADS or the short, easily administered PHQ-2³⁴ or PHQ-4,³⁵ can be used to assess whether patients have symptoms of depression.^1,36,37 Patients at risk for depression or SIB should be referred to their primary care physician or a mental health care practitioner.³⁷ Currently, there is a gap in knowledge in screening patients for psychiatric issues within the dermatology community^33,38; however, health care providers can give support to help bridge this gap.

Psoriasis is a chronic inflammatory skin disorder that affects patients’ quality of life and social interactions.¹ Several studies have shown a strong consistent association between psoriasis and depression as well as possible suicidal ideation and behavior (SIB).^1-13 Notable findings from a 2018 review found depression prevalence ranged from 2.1% to 33.7% among patients with psoriasis vs 0% to 22.7% among unaffected patients.⁷ In a 2017 meta-analysis, Singh et al² found increased odds of SIB (odds ratio [OR], 2.05), attempted suicide (OR, 1.32), and completed suicide (OR, 1.20) in patients with psoriasis compared to those without psoriasis. In 2018, Wu and colleagues⁷ reported that odds of SIB among patients with psoriasis ranged from 1.01 to 1.94 times those of patients without psoriasis, and SIB and suicide attempts were more common than in patients with other dermatologic conditions. Koo and colleagues¹ reached similar conclusions. At the same time, the occurrence of attempted and completed suicides among patients in psoriasis clinical trials has raised concerns about whether psoriasis medications also may increase the risk for SIB.⁷

We review research on the effects of psoriasis treatment on patients’ symptoms of depression and SIB, with a focus on recent analyses of depressive symptoms and SIB among patients with psoriasis who received brodalumab in clinical trials. Finally, we suggest approaches clinicians may consider when caring for patients with psoriasis who may be at risk for depression and SIB.

MATERIALS AND METHODS

We reviewed research on the effects of biologic therapy for psoriasis on depression and SIB, with a primary focus on recent large meta-analyses. Published findings on the pattern of SIB in brodalumab clinical trials and effects of brodalumab treatment on symptoms of depression and anxiety are summarized. The most recent evidence (January 2014–December 2018) regarding the mental health comorbidities of psoriasis was assessed using published English-language research data and review articles according to a PubMed search of articles indexed for MEDLINE using the following terms: depression, anxiety, suicide, suicidal ideation and behavior, SIB, brodalumab, or psoriasis. We also reviewed citations within articles to identify relevant sources. Implications for clinical care of patients with psoriasis are discussed based on expert recommendations and the authors’ clinical experience.

RESULTS

Effects of Psoriasis Treatment on Symptoms of Depression and Suicidality

Occurrences of attempted suicide and completed suicide have been reported during treatment with several psoriasis medications,^7,9 raising concerns about whether these medications increase the risk for depression and SIB in an already vulnerable population. Wu and colleagues⁷ reviewed 11 studies published from 2006 to 2017 reporting the effects of medications for the treatment of psoriasis—adalimumab, apremilast, brodalumab, etanercept, and ustekinumab—on measures of depression and anxiety such as the Beck Depression Inventory, the Hospital Anxiety and Depression Scale (HADS), and the Patient Health Questionnaire (PHQ) 8. In each of the 11 studies, symptoms of depression improved after treatment, over time, or compared to placebo. Notably, the magnitude of improvement in symptoms of depression was not strongly linked to the magnitude of clinical improvement.⁷ Other recent studies have reported reductions in symptoms of depression with biologic therapies, including adalimumab, etanercept, guselkumab, ixekizumab, secukinumab, and ustekinumab.^14-21

With respect to suicidality, an analysis of publicly available data found low rates of completed and attempted suicides (point estimates of 0.0–0.15 per 100 patient-years) in clinical development programs of apremilast, brodalumab, ixekizumab, and secukinumab. Patient suicidality in these trials often occurred in the context of risk factors or stressors such as work, financial difficulties, depression, and substance abuse.⁷ In a detailed 2016 analysis of suicidal behaviors during clinical trials of apremilast, brodalumab, etanercept, infliximab, ixekizumab, secukinumab, tofacitinib, ustekinumab, and other investigational agents, Gooderham and colleagues⁹ concluded that the behaviors may have resulted from the disease or patients’ psychosocial status rather than from treatment and that treatment with biologics does not increase the risk for SIB. Improvements in symptoms of depression during treatment suggest the potential to improve patients’ psychiatric outcomes with biologic treatment.⁹

Evidence From Brodalumab Studies

Intensive efforts have been made to assess the effect of brodalumab, a fully human anti–IL-17RA monoclonal antibody shown to be efficacious in the treatment of moderate to severe plaque psoriasis, on symptoms of depression and to understand the incidence of SIB among patients receiving brodalumab in clinical trials.^22-27

Depression and Anxiety in Studies of Brodalumab
To examine the effects of brodalumab on symptoms of depression, the HADS questionnaire²⁸ was administered to patients in 1 of 3 phase 3 clinical trials of brodalumab.²³ A HADS score of 0 to 7 is considered normal, 8 to 10 is mild, 11 to 14 is moderate, and 15 to 21 is severe.²³ The HADS questionnaire was administered to evaluate the presence and severity of depression and anxiety symptoms at baseline and at weeks 12, 24, 36, and 52.²⁵ This scale was not used in the other 2 phase 3 studies of brodalumab because at the time those studies were initiated, there was no indication to include mental health screenings as part of the study protocol.

Patients were initially randomized to placebo (n=220), brodalumab 140 mg every 2 weeks (Q2W; n=219), or brodalumab 210 mg Q2W (the eventual approved dose; n=222) for 12 weeks.²³ At week 12, patients initially randomized to placebo were switched to brodalumab through week 52. Patients initially randomized to brodalumab 210 mg Q2W were re-randomized to either placebo or brodalumab 210 mg Q2W.²³ Depression and anxiety were common at baseline. Based on HADS scores, depression occurred among 27% and 26% of patients randomized to brodalumab and placebo, respectively; anxiety occurred in 36% of patients in each group.²² Among patients receiving brodalumab 210 mg Q2W from baseline to week 12, HADS depression scores improved in 67% of patients and worsened in 19%. In contrast, the proportion of patients receiving placebo whose depression scores improved (45%) was similar to the proportion whose scores worsened (38%). Hospital Anxiety and Depression Scale anxiety scores also improved more often with brodalumab than with placebo.²²

Furthermore, among patients who had moderate or severe depression or anxiety at baseline, a greater percentage experienced improvement with brodalumab than placebo.²³ Among 30 patients with moderate to severe HADS depression scores at baseline who were treated with brodalumab 210 mg Q2W, 22 (73%) improved by at least 1 depression category by week 12; in the placebo group, 10 of 22 (45%) improved. Among patients with moderate or severe anxiety scores, 28 of 42 patients (67%) treated with brodalumab 210 mg Q2W improved by at least 1 anxiety category compared to 8 of 27 (30%) placebo-treated patients.²³

Over 52 weeks, HADS depression and anxiety scores continued to show a pattern of improvement among patients receiving brodalumab vs placebo.²⁵ Among patients initially receiving placebo, mean HADS depression scores were unchanged from baseline (5.3) to week 12 (5.5). After patients were switched to brodalumab 210 mg Q2W, there was a trend toward improvement between week 12 (5.4) and week 52 (3.1). Among patients initially treated with brodalumab 210 mg Q2W, mean depression scores fell from baseline (5.5) to week 12 (3.4), then rose again between weeks 12 (2.9) and 52 (3.5) in patients switched to placebo (Figure, A). The pattern of findings was similar for HADS anxiety scores (Figure, B).²⁵ Overall, brodalumab treatment appears to improve symptoms of depression and anxiety in patients being treated for psoriasis. This finding is consistent with the effects reported for other biologic therapies previously discussed.

SIB in Studies of Brodalumab
In addition to assessing the effect of brodalumab treatment on symptoms of depression and anxiety in patients with psoriasis, the brodalumab clinical trial program also tracked patterns of SIB among enrolled patients. In contrast with other clinical trials in which patients with a history of psychiatric disorders or substance abuse were excluded, clinical trials of brodalumab did not exclude patients with psychiatric disorders (eg, SIB, depression) and were therefore reflective of the real-world population of patients with moderate to severe psoriasis.²²

In a recently published, detailed analysis of psychiatric adverse events (AEs) in the brodalumab clinical trials, data related to SIB in patients with moderate to severe psoriasis were analyzed from the placebo-controlled phases and open-label, long-term extensions of a placebo-controlled phase 2 clinical trial and from the previously mentioned 3 phase 3 clinical trials.²² From the initiation of the clinical trial program, AEs were monitored during all trials. In response to completed suicides during some studies, additional SIB evaluations were later added at the request of the US Food and Drug Administration, including the Columbia Suicide Severity Rating Scale, the PHQ-8, and the Columbia Classification Algorithm for Suicide Assessment, to independently adjudicate SIB events.²²

In total, 4464 patients in the brodalumab clinical trials received at least 1 dose of brodalumab, and 4126 of these patients received at least 1 dose of brodalumab 210 mg Q2W.²² Total exposure was 9174 patient-years of brodalumab, and mean exposure was 23 months. During the 52-week controlled phases of the clinical trials, 7 patients receiving brodalumab experienced any form of SIB event, representing a time-adjusted incidence rate of 0.20 events (95% confidence interval [CI], 0.08-0.41 events) per 100 patient-years of exposure. During the same 52-week period, patients receiving the comparator drug ustekinumab had an SIB rate of 0.60 events (95% CI, 0.12-1.74 events) per 100 patient-years, which was numerically higher than the rate with brodalumab. Inferential statistical analyses were not performed, but overlapping 95% CIs around these point estimates imply a similar level of SIB risk associated with each agent in these studies. During controlled and uncontrolled treatment periods in all studies, the SIB rate among brodalumab-treated patients was 0.37 events per 100 patient-years.²²

Over all study phases, 3 completed suicides and 1 case adjudicated as indeterminate by the Columbia Classification Algorithm for Suicide Assessment review board were reported.²² All occurred in men aged 39 to 59 years. Of 6 patients with an AE of suicide attempt, all patients had at least 1 SIB risk factor and 3 had a history of SIB. The rate of SIB events was greater in patients with a history of depression (1.42) or suicidality (3.21) compared to those without any history of depression or suicidality (0.21 and 0.20, respectively).²² An examination of the regions in which the brodalumab studies were conducted showed generally consistent SIB incidence rates: 0.52, 0.29, 0.77, and 0 events per 100 patient-years in North America, Europe, Australia, and Russia, respectively.²⁴

As previously described, depression and other risk factors for SIB are prevalent among patients with psoriasis. In addition, the rate of suicide mortality has increased substantially over the last decade in the general population, particularly among middle-aged white men,²⁹ who made up much of the brodalumab clinical trial population.²² Therefore, even without treatment, it would not be surprising that SIB events occurred during the brodalumab trials. Most patients with SIB events during the trials had a history of predisposing risk factors.²² Prescribing information for brodalumab in the United States includes a boxed warning advising physicians to be aware of the risk of SIB as well as a statement that a causal relationship between SIB and brodalumab treatment has not been established.²⁷

Obstetricians face the potential practice dilemma of having withdrawn from the market the only drug approved by the US Food and Drug Administration (FDA) for the prevention of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth. In the recently published PROLONG (Progestin's Role in Optimizing Neonatal Gestation) study by Blackwell and colleagues, the trial results revealed that there were no significant differences in preterm birth between women treated with 17 α-hydroxyprogesterone caproate (17P; Makena) and those who received placebo.¹ For study details and comments, see "Progesterone supplementation does not PROLONG pregnancy in women at risk for preterm birth: What do we do now?" by Michael House, MD, and Errol Norwitz, MD, PhD, MBA. Subsequently, the FDA's Bone, Reproductive and Urologic Drugs Advisory Committee voted 9-7 to recommend pursuit of approval withdrawal for 17P. 

To assess how experienced obstetricians would manage women with previous preterm birth if 17P became unavailable, OBG Management conducted an informal survey. Here, 4 experts respond to the question, "What are you going to do in your practice for women with a history of a previous preterm birth if 17P is no longer an option?"

Not ready to leave behind 17P for recurrent preterm delivery

Patrick Duff, MD 

Preterm delivery is arguably the most important problem in perinatal medicine. It occurs in 10% to 12% of all obstetric patients in the United States, and complications of prematurity account for the majority of neonatal deaths. A major risk factor for recurrent preterm delivery is a prior history of spontaneous preterm delivery, with or without preterm premature rupture of membranes. Clearly, prevention of recurrence is of paramount importance. 

In the Maternal-Fetal Medicine Units (MFMU) Network trial, Meis and colleagues demonstrated a 34% reduction (relative risk [RR], 0.66; 95% confidence interval [CI], 0.54-0.81) in the risk of recurrent preterm delivery in women who received weekly 250-mg injections of 17P (also called 17-OHPC). After publication of that trial, use of 17P became accepted practice in the United States.² 

The PROLONG study by Blackwell and colleagues questions the value of 17P.¹ In that international trial, which included 1,708 women from 41 centers in the United States and 52 outside the United States, the authors were unable to show any significant difference in the frequency of preterm delivery < 35 weeks (11.0% in the women receiving 17P and 11.5% in women receiving placebo; RR, 0.95; 95% CI, 0.71-1.26). Even when they examined the subset of women treated at US medical centers, they could not demonstrate any significant difference in treatment outcome.  

At least 2 major explanations account for the discrepancy between the MFMU and the Blackwell studies. First, the participants in the PROLONG trial were clearly not at the same increased risk for recurrent preterm delivery as those in the MFMU trial. Second, in the PROLONG trial only the minority of participants were from the United States. In fact, given the relatively low rate of recurrent preterm delivery in the PROLONG trial, the study was underpowered to detect meaningful differences in maternal outcome. Therefore, I am not ready to abandon the use of progesterone supplementation in women at risk for recurrent preterm delivery. 

Continue to: If the FDA removes 17P from the market...

If the FDA removes 17P from the market, my approach with at-risk patients will be as follows: 

• I will encourage all at-risk women to eliminate obvious risk factors, such as smoking, illicit drug use, and excessive physical activity. 
• I will encourage optimal nutrition and appropriate weight gain. 
• I will test all patients for chlamydia, gonorrhea, and bacterial vaginosis and treat women who are infected. 
• After the patient completes the first trimester, I will treat her with micronized progesterone, 200 mg daily, intravaginally. I will continue this medication until 36 to 37 weeks. 
• I will perform an assessment of cervical length at 16, 20, and 24 weeks' gestation. In patients with demonstrable cervical shortening, I will perform a cerclage.

Rational management options for reducing risk of preterm delivery

Alex C. Vidaeff, MD, MPH 

Most women who experience a spontaneous preterm delivery (sPTD) do not deliver prematurely in subsequent pregnancies.³ Two recent systematic reviews, in 2014 and 2017, found an overall risk of recurrent sPTD of 20.2% and 30%, respectively.^4,5 These numbers are closer to the background event rate of 21.9% in the PROLONG trial, while only a few women have a recurrence risk of more than 50%, as in the Meis MFMU trial.^1,2 A public health recommendation cannot be made for an intervention that is expected to work only in rare cases and fail in a majority of cases. Therefore, 17P is no longer a viable option for preventing recurrence in pregnant women with a history of sPTD, with only rare possible exceptions.

What evidence-based alternatives can be offered to pregnant women who had a previous sPTD?

Ultrasound assessment of cervical length has emerged as an effective prognosticator for recurrence in women with a prior sPTD, being able to predict 65.4% of sPTDs at a false-positive rate of 5%.^6,7 Furthermore, sonographic cervical length measurements identify high-risk women who may not need any intervention. It has been shown that, among women with prior sPTD who maintain a normal cervical length up to 24 weeks, more than 90% will deliver at 35 weeks or after without intervention.⁸  

In the United States, interventions to reduce sPTD, once a short cervix has been identified, include vaginal progesterone supplementation and cerclage. The benefit from vaginal progesterone has been documented by an individual patient data meta-analysis, while the benefit of cerclage has been highlighted in a Cochrane Review.^9,10 The results of an adjusted indirect comparison meta-analysis suggest that both interventions are equally effective.¹¹ Therefore, the decision on how best to minimize the risk of recurrent sPTD must be individualized based on historical and clinical circumstances, as well as the woman's informed choice.  

Based on current data, the following approach appears rational to me: 

• Cervical ultrasound surveillance between 16 and 24 weeks' gestation to identify the subgroup of women at significantly increased risk of sPTD recurrence. 
• With cervical length ≤ 25 mm, vaginal progesterone supplementation may be considered. Preferential consideration for progesterone may be given when lower genital tract inflammation is suspected, given the possible anti-inflammatory action of progesterone.^12,13 
• If cervical shortening progresses to 15 to 20 mm, cerclage may be considered. Waiting for a cervix < 15 mm may be unadvisable. In conditions of a very short cervix, frequently dilated, with exposure of the fetal membranes, ascending subclinical intra-amniotic infection already may be present, reducing the efficacy of cerclage. Preferential consideration for cerclage also may be given with 2 sPTDs or mid-trimester losses or with a history of a successful cerclage. 

Continue to: Screen cervical length early, and use cerclage or vaginal progesterone as appropriate...

Screen cervical length early, and use cerclage or vaginal progesterone as appropriate

Michael G. Ross, MD, MPH

In patients with a history of a previous preterm birth, if 17P is no longer an option, I would revert to screening for short cervix with transvaginal ultrasound.  

Screen all high-risk patients at the first prenatal visit, so as not to miss a short cervix before 16 weeks' gestation. Then, beginning at 16 weeks, screen every 2 weeks until approximately 24 weeks.  

If the cervix shortens to 25 mm or less, offer cerclage or vaginal progesterone. If the cervix shortens to 20 mm or less, I would strongly support cerclage or vaginal progesterone. 

Use of 17P is still an option, for now 

Errol R. Norwitz, MD, PhD, MBA 

The way in which 17P was handled by the FDA is exactly the way the system is designed to work; this should be seen as a success, not a failure.  

Given the urgent need for an intervention to prevent preterm birth, the lack of any alternative, and a single, well-designed randomized controlled trial that confirmed safety and suggested some benefit, the FDA approved 17P supplementation in February 2011 for a limited indication only—one or more prior unexplained sPTD—using the expedited review mechanism.² Under this mechanism, a follow-up clinical trial is required to confirm efficacy. This was the PROLONG trial, which failed to show any significant benefit of 17P supplementation in terms of either preterm birth prevention or neonatal outcome.¹ 

In October 2019, an FDA advisory committee met again to review these and other data. After presentations from a range of stakeholders and a robust discussion, the advisory committee voted to pursue approval withdrawal of 17P due to the lack of consistent evidence of benefit (it is important to note that this was not because of safety concerns). This is exactly the way the process is designed to work. 

Where does this leave physicians and patients? It is clear that progesterone supplementation is not a panacea for preterm birth prevention and is not indicated for all women at high risk, even those with one or more prior unexplained sPTDs. Given that preterm birth is a syndrome and not a single diagnosis, it is still possible that there is a subgroup of women who may benefit from this intervention. For this reason—and because there is no clear alternative and no known downside to the administration of this drug (other than cost)—physicians still may choose to discuss this option with their patients and, after counseling, patients still may choose to accept it. If in doubt, engage the "shared decision-making model"; talk to your patients.  

Obstetricians face the potential practice dilemma of having withdrawn from the market the only drug approved by the US Food and Drug Administration (FDA) for the prevention of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth.

The benefit from vaginal progesterone has been documented by an individual patient data meta-analysis, while the benefit of cerclage has been highlighted in a Cochrane Review.^9,10 The results of an adjusted indirect comparison meta-analysis suggest that both interventions are equally effective.¹¹ Therefore, the decision on how best to minimize the risk of recurrent sPTD must be individualized based on historical and clinical circumstances, as well as the woman's informed choice.  

Based on current data, the following approach appears rational to me: 

• Cervical ultrasound surveillance between 16 and 24 weeks' gestation to identify the subgroup of women at significantly increased risk of sPTD recurrence. 
• With cervical length ≤ 25 mm, vaginal progesterone supplementation may be considered. Preferential consideration for progesterone may be given when lower genital tract inflammation is suspected, given the possible anti-inflammatory action of progesterone.^12,13 
• If cervical shortening progresses to 15 to 20 mm, cerclage may be considered. Waiting for a cervix < 15 mm may be unadvisable. In conditions of a very short cervix, frequently dilated, with exposure of the fetal membranes, ascending subclinical intra-amniotic infection already may be present, reducing the efficacy of cerclage. Preferential consideration for cerclage also may be given with 2 sPTDs or mid-trimester losses or with a history of a successful cerclage.

Screen cervical length early, and use cerclage or vaginal progesterone as appropriate

Michael G. Ross, MD, MPH

In patients with a history of a previous preterm birth, if 17P is no longer an option, I would revert to screening for short cervix with transvaginal ultrasound.  

Screen all high-risk patients at the first prenatal visit, so as not to miss a short cervix before 16 weeks' gestation. Then, beginning at 16 weeks, screen every 2 weeks until approximately 24 weeks.  

If the cervix shortens to 25 mm or less, offer cerclage or vaginal progesterone. If the cervix shortens to 20 mm or less, I would strongly support cerclage or vaginal progesterone. 

Use of 17P is still an option, for now 

Errol R. Norwitz, MD, PhD, MBA 

The way in which 17P was handled by the FDA is exactly the way the system is designed to work; this should be seen as a success, not a failure.  

Given the urgent need for an intervention to prevent preterm birth, the lack of any alternative, and a single, well-designed randomized controlled trial that confirmed safety and suggested some benefit, the FDA approved 17P supplementation in February 2011 for a limited indication only—one or more prior unexplained sPTD—using the expedited review mechanism.² Under this mechanism, a follow-up clinical trial is required to confirm efficacy. This was the PROLONG trial, which failed to show any significant benefit of 17P supplementation in terms of either preterm birth prevention or neonatal outcome.¹ 

In October 2019, an FDA advisory committee met again to review these and other data. After presentations from a range of stakeholders and a robust discussion, the advisory committee voted to pursue approval withdrawal of 17P due to the lack of consistent evidence of benefit (it is important to note that this was not because of safety concerns). This is exactly the way the process is designed to work. 

Where does this leave physicians and patients? It is clear that progesterone supplementation is not a panacea for preterm birth prevention and is not indicated for all women at high risk, even those with one or more prior unexplained sPTDs. Given that preterm birth is a syndrome and not a single diagnosis, it is still possible that there is a subgroup of women who may benefit from this intervention. For this reason—and because there is no clear alternative and no known downside to the administration of this drug (other than cost)—physicians still may choose to discuss this option with their patients and, after counseling, patients still may choose to accept it. If in doubt, engage the "shared decision-making model"; talk to your patients.  

Obstetricians face the potential practice dilemma of having withdrawn from the market the only drug approved by the US Food and Drug Administration (FDA) for the prevention of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth. In the recently published PROLONG (Progestin's Role in Optimizing Neonatal Gestation) study by Blackwell and colleagues, the trial results revealed that there were no significant differences in preterm birth between women treated with 17 α-hydroxyprogesterone caproate (17P; Makena) and those who received placebo.¹ For study details and comments, see "Progesterone supplementation does not PROLONG pregnancy in women at risk for preterm birth: What do we do now?" by Michael House, MD, and Errol Norwitz, MD, PhD, MBA. Subsequently, the FDA's Bone, Reproductive and Urologic Drugs Advisory Committee voted 9-7 to recommend pursuit of approval withdrawal for 17P. 

To assess how experienced obstetricians would manage women with previous preterm birth if 17P became unavailable, OBG Management conducted an informal survey. Here, 4 experts respond to the question, "What are you going to do in your practice for women with a history of a previous preterm birth if 17P is no longer an option?"

Not ready to leave behind 17P for recurrent preterm delivery

Patrick Duff, MD 

Preterm delivery is arguably the most important problem in perinatal medicine. It occurs in 10% to 12% of all obstetric patients in the United States, and complications of prematurity account for the majority of neonatal deaths. A major risk factor for recurrent preterm delivery is a prior history of spontaneous preterm delivery, with or without preterm premature rupture of membranes. Clearly, prevention of recurrence is of paramount importance. 

In the Maternal-Fetal Medicine Units (MFMU) Network trial, Meis and colleagues demonstrated a 34% reduction (relative risk [RR], 0.66; 95% confidence interval [CI], 0.54-0.81) in the risk of recurrent preterm delivery in women who received weekly 250-mg injections of 17P (also called 17-OHPC). After publication of that trial, use of 17P became accepted practice in the United States.² 

The PROLONG study by Blackwell and colleagues questions the value of 17P.¹ In that international trial, which included 1,708 women from 41 centers in the United States and 52 outside the United States, the authors were unable to show any significant difference in the frequency of preterm delivery < 35 weeks (11.0% in the women receiving 17P and 11.5% in women receiving placebo; RR, 0.95; 95% CI, 0.71-1.26). Even when they examined the subset of women treated at US medical centers, they could not demonstrate any significant difference in treatment outcome.  

At least 2 major explanations account for the discrepancy between the MFMU and the Blackwell studies. First, the participants in the PROLONG trial were clearly not at the same increased risk for recurrent preterm delivery as those in the MFMU trial. Second, in the PROLONG trial only the minority of participants were from the United States. In fact, given the relatively low rate of recurrent preterm delivery in the PROLONG trial, the study was underpowered to detect meaningful differences in maternal outcome. Therefore, I am not ready to abandon the use of progesterone supplementation in women at risk for recurrent preterm delivery.

If the FDA removes 17P from the market, my approach with at-risk patients will be as follows: 

• I will encourage all at-risk women to eliminate obvious risk factors, such as smoking, illicit drug use, and excessive physical activity. 
• I will encourage optimal nutrition and appropriate weight gain. 
• I will test all patients for chlamydia, gonorrhea, and bacterial vaginosis and treat women who are infected. 
• After the patient completes the first trimester, I will treat her with micronized progesterone, 200 mg daily, intravaginally. I will continue this medication until 36 to 37 weeks. 
• I will perform an assessment of cervical length at 16, 20, and 24 weeks' gestation. In patients with demonstrable cervical shortening, I will perform a cerclage.

Rational management options for reducing risk of preterm delivery

Alex C. Vidaeff, MD, MPH 

Most women who experience a spontaneous preterm delivery (sPTD) do not deliver prematurely in subsequent pregnancies.³ Two recent systematic reviews, in 2014 and 2017, found an overall risk of recurrent sPTD of 20.2% and 30%, respectively.^4,5 These numbers are closer to the background event rate of 21.9% in the PROLONG trial, while only a few women have a recurrence risk of more than 50%, as in the Meis MFMU trial.^1,2 A public health recommendation cannot be made for an intervention that is expected to work only in rare cases and fail in a majority of cases. Therefore, 17P is no longer a viable option for preventing recurrence in pregnant women with a history of sPTD, with only rare possible exceptions.

What evidence-based alternatives can be offered to pregnant women who had a previous sPTD?

Ultrasound assessment of cervical length has emerged as an effective prognosticator for recurrence in women with a prior sPTD, being able to predict 65.4% of sPTDs at a false-positive rate of 5%.^6,7 Furthermore, sonographic cervical length measurements identify high-risk women who may not need any intervention. It has been shown that, among women with prior sPTD who maintain a normal cervical length up to 24 weeks, more than 90% will deliver at 35 weeks or after without intervention.⁸  

In the United States, interventions to reduce sPTD, once a short cervix has been identified, include vaginal progesterone supplementation and cerclage. The benefit from vaginal progesterone has been documented by an individual patient data meta-analysis, while the benefit of cerclage has been highlighted in a Cochrane Review.^9,10 The results of an adjusted indirect comparison meta-analysis suggest that both interventions are equally effective.¹¹ Therefore, the decision on how best to minimize the risk of recurrent sPTD must be individualized based on historical and clinical circumstances, as well as the woman's informed choice.
