For people with clinically diagnosed “nightmare disorder,” learning to redirect disturbing dreams to more positive ones is usually the return ticket to sleep. 

But for nearly one-third of people, that method – called imagery rehearsal therapy – isn’t effective.

A new study shows that listening to positive sounds while sleeping reduces the frequency of nightmares.

“This is a promising development. It does appear that adding a well-timed sound during REM sleep augments the effect of image rehearsal therapy ... which is a standard and perhaps one of the most effective nonpharmacologic therapies at this time,” said Timothy Morgenthaler, MD, in an interview with CNN. 

Dr. Morgenthaler, who was not involved in this latest study, is lead author of the American Academy of Sleep Medicine’s current guidelines on nightmares.

For the new research, nightmares were defined as “the experience of strong negative emotions occurring usually during REM sleep. They involve images and thoughts of aggression, interpersonal conflict, and failure, and emotions like fear, anger, and sadness.” Nightmare disorder is characterized as having such dreams so frequently that they cause “significant distress or impairment in social, occupational, or other important areas of functioning.” 

Left untreated, nightmare disorder can persist for decades, the authors said.

The study, conducted in Switzerland, enrolled 36 participants with nightmare disorder. All 36 participated in a daytime lesson of imagery rehearsal therapy that taught them to redirect their nightmares to positive dreams. Participants were taught to recall a nightmare, change the negative story line toward a more positive one, and then rehearse the so-called “rewritten dream” during the day.

Half of the participants also had a special sound played while they practiced reimagining their new positive dreams. At night for the following 2 weeks while they slept, the sound was played during their REM cycles.

Those who heard the sound reported significantly fewer nightmares.

“This difference displayed a medium to large effect size and was sustainable at the 3-month follow-up,” the authors reported.

They did note that both groups showed improvement, likely because the lesson to reimagine nightmares into positive dreams is known to be effective. However, the authors allowed that other factors may have contributed in ways their study design could not control.

“The result should be replicated,” Dr. Morgenthaler said. “But I was a bit excited at this new possibility.”

THE CASE

A 26-year-old woman presented to the emergency department (ED) with a history of nausea and vomiting for more than 24 hours. The vomiting began when she awoke to breastfeed her 3-month-old infant. She had been unable to eat or drink anything for about 16 hours.

She’d seen her primary care provider earlier in the day. Antiemetics were prescribed, but they did not provide relief. So 10 hours later, when her symptoms worsened, she presented to the ED.

Her medical history was notable for a body mass index of 26. The patient also reported positional back pain, but the review of systems was otherwise negative. The patient indicated that she’d been on a ketogenic diet for about 1 month, but she denied use of supplements.

Upon presentation to the ED, the patient was found to have a metabolic acidosis with a pH of 7.02 and an anion gap of 25. Her glucose level was 132 mg/dL, and she had a positive serum acetone and a beta-hydroxybutyrate level of 75 mg/dL (reference range, 0-2.8 mg/dL). Her salicylate testing was negative, and her lactate level was 1.4 mmol/L (reference range, 0.4-2.0 mmol/L).

THE DIAGNOSIS

This patient, with severe acidosis and an elevated anion gap, received a diagnosis of starvation ketoacidosis—specifically, lactation ketoacidosis. Other causes of elevated anion gap metabolic acidosis were ruled out, including salicylate overdose, lactic acidosis, diabetic ketoacidosis, and other ingestions. The elevated acetone and beta-hydroxybutyrate levels confirmed the diagnosis. The patient was treated with a bolus of 1 L normal saline with 5% dextrose (D5NS) in the ED and admitted.

DISCUSSION

Lactation ketoacidosis is a relatively uncommon condition, but reports have increased with the growing popularity of low-carbohydrate diets. The treatment approach has differed in previous reports in regard to insulin and bicarbonate use.^1-9

The use of bicarbonate is controversial in diabetic ketoacidosis and unlikely to be helpful in lactation ketoacidosis, but it is something to consider when the patient’s pH is < 6.9. Insulin use is likely unnecessary for lactation ketoacidosis, as metabolic derangements have been corrected without intervention.

Continue to: With an increasing prevalence of cases...

With an increasing prevalence of cases, we suggest a conservative approach for treatment based on this case presentation and review of other presentations. Our patient responded rapidly to conservative treatment with intravenous (IV) fluids (D5NS), a liberalized diet, and electrolyte repletion (described in detail later).

Suggested management

Once other causes of a patient’s signs and symptoms are excluded and the diagnosis of lactation ketoacidosis is made, you’ll want to follow the initial set of lab work with the following: a venous blood gas, basic metabolic panel, and testing of magnesium and phosphorous levels every 8 hours after initial presentation, with repletion as indicated. Some patients may require more frequent monitoring based on repletion of electrolytes.

The patient will initially require IV fluid resuscitation; the initial fluid of choice would be D5NS. Patients will likely need no more than 2 L, but this will depend on the degree of hypovolemia.

Lactation ketoacidosis is a relatively uncommon condition, but reports have increased with the growing popularity of low-carbohydrate diets.

Diet should be advanced as tolerated and include no restriction of carbohydrates.

Previous reports have varied regarding continuation of breastfeeding and pumping. In this case, the patient continued to breastfeed without any adverse effects. Continuation of breastfeeding is unlikely to cause harm in these circumstances, but severity of symptoms (pain, nausea, vomiting) or unresolved acidosis may require discontinuation.

Continue to: Discharge should be determined...

Discharge should be determined by resolution of symptoms and correction of metabolic derangements. In previous reports, discharge time varied from 48 hours up to 144 hours, with most patients discharged on Day 2 or 3. Pending clinical factors, discharge is likely appropriate between 36 to 72 hours from time of admission.

Our patient received an additional 1 L of D5NS for continued signs of dehydration during admission. Her pH and electrolyte levels were monitored every 8 hours, with repletion of electrolytes as needed. Her acidosis, nausea, vomiting, and pain resolved within 36 hours. The patient continued to breastfeed her infant throughout her stay. With resolution of symptoms and metabolic derangements, the patient was discharged about 36 hours after admission. She was advised to follow up with her primary care provider within 1 week after discharge.

THE TAKEAWAY

As the popularity of low-carbohydrate diets increases, patients should be educated about the warning signs of clinically significant ketoacidosis. This information is especially important for those who are lactating, as this metabolic state increases predilection to ketoacidosis. When cases do present, conservative management with IV fluids and a liberalized diet is likely to be an appropriate course of care for most patients.

THE CASE

Alex T,* a 23-year-old first-time mom, presented to the family medicine office for her baby’s 2-week appointment. When asked how she was doing, she began to cry. She said, “I feel crazy” and indicated that she was feeling down and overwhelmed, and was struggling to bond with the baby. She filled out an Edinburgh Postnatal Depression Scale, a standard postpartum depression (PPD) screen; her score, 15 out of 30, was suggestive of depression. Ms. T had been coming to the practice for the past 3 years and had no significant physical or mental health history. She and the baby did not live with the baby’s father, and his degree of presence in their lives varied.

●How would you proceed with this patient?

* The patient’s name has been changed to protect her identity.

PPD, traditionally defined as depression in the postpartum period for as long as a year after childbirth, is a common, underdiagnosed outcome of both normal and complicated pregnancies.¹ Peripartum depression, which includes PPD and depression during pregnancy, occurs in approximately 10% of pregnancies.^2,3 When depression first appears in the postpartum period, most women develop symptoms in the first month after delivery (54% of cases) or in the next 2 to 4 months (40%).⁴

The most significant risk factor for PPD is previous depression, peripartum or otherwise.^1,4-6 Other common risk factors include major life events or stressors during or after pregnancy, domestic violence, poor social support, and preterm birth or an infant admission to the neonatal intensive care unit.^1,7 Women with a self-perceived negative birth experience are also likely to experience PPD.⁸ PPD can be associated with significant morbidity and mortality, with suicide a more common cause of maternal mortality than either hemorrhage or hypertensive disorders of pregnancy.⁹

Women with postpartum anemia and low ferritin stores are more prone to depression than are those with normal levels.

Early diagnosis and intervention are crucial to improving patient outcomes. Women with PPD initiate breastfeeding at lower rates and continue for shorter durations.¹⁰ PPD also affects maternal–infant bonding; may adversely affect an infant’s social, cognitive, and language development; and may lead to attachment disorders of infancy.^11,12 In severe cases, it can lead to failure to thrive or infanticide.¹¹

When to screen. The US Preventive Services Task Force (USPSTF) recommends clinicians screen for depression in pregnant and postpartum women (Grade B^a) and for women at increased risk, provide or refer to counseling interventions (Grade B^a).^13,14 The American College of Obstetricians and Gynecologists (ACOG) recommends screening at least once in the postpartum period.¹⁵ Repeat screening at follow-up in the later postpartum period increases the likelihood of diagnosis.¹⁶ Screening for PPD as part of well-child care improves maternal outcomes, and the American Academy of Pediatrics recommends screening at the 1-, 2-, 4-, and 6-month visits.^11,17 These screens are separately billable. Family physicians are uniquely suited to screening at both well-child and postpartum visits, as many women share a medical home with their child, and those who do not are equally willing to receive medical advice from their child’s physician.¹⁸

Continue to: Is it "the blues" or something else? Diagnosing PPD

Many new mothers experience postpartum blues, which manifest as tearfulness, insomnia, irritability, and anxiety. The postpartum blues, however, don’t meet the criteria for major depressive disorder and typically resolve within 14 days of delivery.^19-21 On the other end of the spectrum is postpartum psychosis, which is severe and rare, and can also affect new mothers.

Screening for PPD. The most commonly used screening tool for PPD is the Edinburgh Postnatal Depression Scale (EPDS 10), a free 10-item instrument scored out of 30 possible points, with any score ≥ 13 suggesting PPD.²² The EPDS 10 has a sensitivity of 74% and specificity of 97% for the diagnosis of PPD.²³ Other screening options include the Beck Depression Inventory II (BDI-II) and the Patient Health Questionnaire 9 (PHQ-9). The 21-item BDI-II takes longer to perform and is less sensitive (57%) than the EPDS.¹ The PHQ-9, which asks about some symptoms common to the postpartum period (including sleep changes), is less specific than the EPDS (sensitivity, 75%; specificity, 90%).¹ The EPDS also includes screening questions about anxiety.¹

A positive depression screen, or any positive response to a question on suicidal ideation, should be followed up for confirmation using the Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-5) criteria for major depressive disorder with peripartum onset.²⁴ Women with PPD should also be asked about current or prior symptoms of bipolar disorder or mania.²⁵ Up to 67% of women with bipolar disorder may relapse postpartum, and they also have an elevated risk of postpartum psychosis.²⁶ The Mood Disorder Questionnaire is a useful tool if a concern for bipolar depression arises.²⁷

Refer any woman in whom bipolar depression is a concern to a clinician experienced with its management. The presence of auditory or visual hallucinations should also be assessed as indicators of postpartum psychosis. Active suicidal or homicidal ideation and postpartum psychosis all require emergent psychiatric care.^21,22 Intimate partner violence may also exist or escalate in the postpartum period and may exacerbate PPD. Both ACOG and the USPSTF recommend screening postpartum women for intimate partner violence.^28,29

Also consider possible medical causes of PPD symptoms. Hypothyroidism in the postpartum period may manifest with some similar symptoms to PPD and is commonly underdiagnosed.^22,30 Women with postpartum anemia and low ferritin stores also have a higher likelihood of PPD (odds ratio, 1.7-4.64), and postpartum iron supplementation may reduce this risk (number needed to treat = 4 in at least 1 randomized controlled trial).³¹ When anemia is present, ensure that it is properly treated.

Continue to: Steps you can take to manage pPD

Refer any woman who has PPD to a qualified therapist whenever possible. Generally, the psychological recommendations for treatment of PPD are very similar to recommendations for general treatment of depression. Psychotherapy on its own is considered a first-line treatment for mild-to-moderate PPD, and medication plus psychotherapy is considered first-line treatment for severe PPD.³² (Worth noting: It may also be useful to offer counseling to a patient who appears distressed, even if she does not fully meet all DSM-5 criteria.)

Of the psychotherapy options, cognitive behavioral therapy is supported by the most evidence.

Of the psychotherapy options, cognitive behavioral therapy (CBT) is supported by the most evidence. There is also evidence for the use of interpersonal therapy (IPT), especially in higher socioeconomic status populations.³³ Key therapeutic targets in IPT are increasing behavioral engagement (eg, reaching out to friends), decreasing negative self-talk (eg, “I am a bad mother”), and negotiating roles and support (eg, both mom’s and family members’ expectations of new motherhood). There is mixed evidence for recommending exercise as a treatment for PPD.^32,34 However, as exercise is a low-risk intervention, you may choose to make that recommendation to patients. Additionally, including partners/support people in treatment/visits for PPD has been shown to increase positive outcomes.³⁵

When medication is considered, selective serotonin reuptake inhibitors (SSRIs) are most commonly used. Research indicates that SSRIs are significantly more effective than placebo for treatment of women with PPD.³⁶ Sertraline, in particular, has shown to be both effective in treating PPD and safe in lactation.^37,38 Dosing and duration of therapy are equivalent to treatment of major depression outside the perinatal period. Consult a trusted source on medications in lactation before prescribing any antidepressant to a breastfeeding mother. One resource is the National Institutes of Health drugs and lactation database (LactMed; www.ncbi.nlm.nih.gov/books/NBK501922/), which provides detailed information on the levels of medications in breastmilk and their potential effects on an infant.

Women with severe, refractory PPD may require hospitalization. Additional treatment options for women with severe, refractory PPD include electroconvulsive therapy or the new medication brexanolone, which is administered as a 60-hour continuous infusion.^39,40

THE CASE

Further conversation with Ms. T revealed that she met the criteria for PPD (major depressive disorder with peripartum onset). She denied suicidal or homicidal ideation and was not experiencing any symptoms of psychosis. A complete blood count was drawn and showed no anemia, and her thyroid-stimulating hormone level was within normal limits. She had a good support network at home, with both her mom and sister taking shifts to help her get some extra rest and allow her to attend medical appointments. She said there was no domestic violence.

Ms. T was introduced to the clinic’s embedded counselor, who scheduled a follow-up appointment within the week to start CBT. After a discussion of risks and benefits, Ms. T also started a low dose of sertraline once daily. At follow-up postpartum visits, she reported significant improvement in her mood. She and her physician decided to taper her SSRI medication at 3 months postpartum. Screens for depression at her infant’s 4- and 6-month well-child visits in the office were reassuringly negative.

The most commonly used screening tool for PPD is the Edinburgh Postnatal Depression Scale (EPDS 10), a free 10-item instrument scored out of 30 possible points, with any score ≥ 13 suggesting PPD.²² The EPDS 10 has a sensitivity of 74% and specificity of 97% for the diagnosis of PPD.²³ Other screening options include the Beck Depression Inventory II (BDI-II) and the Patient Health Questionnaire 9 (PHQ-9). The 21-item BDI-II takes longer to perform and is less sensitive (57%) than the EPDS.¹ The PHQ-9, which asks about some symptoms common to the postpartum period (including sleep changes), is less specific than the EPDS (sensitivity, 75%; specificity, 90%).¹ The EPDS also includes screening questions about anxiety.¹

A positive depression screen, or any positive response to a question on suicidal ideation, should be followed up for confirmation using the Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-5) criteria for major depressive disorder with peripartum onset.²⁴ Women with PPD should also be asked about current or prior symptoms of bipolar disorder or mania.²⁵ Up to 67% of women with bipolar disorder may relapse postpartum, and they also have an elevated risk of postpartum psychosis.²⁶ The Mood Disorder Questionnaire is a useful tool if a concern for bipolar depression arises.²⁷

Refer any woman in whom bipolar depression is a concern to a clinician experienced with its management. The presence of auditory or visual hallucinations should also be assessed as indicators of postpartum psychosis. Active suicidal or homicidal ideation and postpartum psychosis all require emergent psychiatric care.^21,22 Intimate partner violence may also exist or escalate in the postpartum period and may exacerbate PPD. Both ACOG and the USPSTF recommend screening postpartum women for intimate partner violence.^28,29

Also consider possible medical causes of PPD symptoms. Hypothyroidism in the postpartum period may manifest with some similar symptoms to PPD and is commonly underdiagnosed.^22,30 Women with postpartum anemia and low ferritin stores also have a higher likelihood of PPD (odds ratio, 1.7-4.64), and postpartum iron supplementation may reduce this risk (number needed to treat = 4 in at least 1 randomized controlled trial).³¹ When anemia is present, ensure that it is properly treated.

Refer any woman who has PPD to a qualified therapist whenever possible. Generally, the psychological recommendations for treatment of PPD are very similar to recommendations for general treatment of depression. Psychotherapy on its own is considered a first-line treatment for mild-to-moderate PPD, and medication plus psychotherapy is considered first-line treatment for severe PPD.³² (Worth noting: It may also be useful to offer counseling to a patient who appears distressed, even if she does not fully meet all DSM-5 criteria.)

Of the psychotherapy options, cognitive behavioral therapy is supported by the most evidence.

Of the psychotherapy options, cognitive behavioral therapy (CBT) is supported by the most evidence. There is also evidence for the use of interpersonal therapy (IPT), especially in higher socioeconomic status populations.³³ Key therapeutic targets in IPT are increasing behavioral engagement (eg, reaching out to friends), decreasing negative self-talk (eg, “I am a bad mother”), and negotiating roles and support (eg, both mom’s and family members’ expectations of new motherhood). There is mixed evidence for recommending exercise as a treatment for PPD.^32,34 However, as exercise is a low-risk intervention, you may choose to make that recommendation to patients. Additionally, including partners/support people in treatment/visits for PPD has been shown to increase positive outcomes.³⁵

When medication is considered, selective serotonin reuptake inhibitors (SSRIs) are most commonly used. Research indicates that SSRIs are significantly more effective than placebo for treatment of women with PPD.³⁶ Sertraline, in particular, has shown to be both effective in treating PPD and safe in lactation.^37,38 Dosing and duration of therapy are equivalent to treatment of major depression outside the perinatal period. Consult a trusted source on medications in lactation before prescribing any antidepressant to a breastfeeding mother. One resource is the National Institutes of Health drugs and lactation database (LactMed; www.ncbi.nlm.nih.gov/books/NBK501922/), which provides detailed information on the levels of medications in breastmilk and their potential effects on an infant.

Women with severe, refractory PPD may require hospitalization. Additional treatment options for women with severe, refractory PPD include electroconvulsive therapy or the new medication brexanolone, which is administered as a 60-hour continuous infusion.^39,40

THE CASE

Further conversation with Ms. T revealed that she met the criteria for PPD (major depressive disorder with peripartum onset). She denied suicidal or homicidal ideation and was not experiencing any symptoms of psychosis. A complete blood count was drawn and showed no anemia, and her thyroid-stimulating hormone level was within normal limits. She had a good support network at home, with both her mom and sister taking shifts to help her get some extra rest and allow her to attend medical appointments. She said there was no domestic violence.

Ms. T was introduced to the clinic’s embedded counselor, who scheduled a follow-up appointment within the week to start CBT. After a discussion of risks and benefits, Ms. T also started a low dose of sertraline once daily. At follow-up postpartum visits, she reported significant improvement in her mood. She and her physician decided to taper her SSRI medication at 3 months postpartum. Screens for depression at her infant’s 4- and 6-month well-child visits in the office were reassuringly negative.

THE CASE

Alex T,* a 23-year-old first-time mom, presented to the family medicine office for her baby’s 2-week appointment. When asked how she was doing, she began to cry. She said, “I feel crazy” and indicated that she was feeling down and overwhelmed, and was struggling to bond with the baby. She filled out an Edinburgh Postnatal Depression Scale, a standard postpartum depression (PPD) screen; her score, 15 out of 30, was suggestive of depression. Ms. T had been coming to the practice for the past 3 years and had no significant physical or mental health history. She and the baby did not live with the baby’s father, and his degree of presence in their lives varied.

PPD, traditionally defined as depression in the postpartum period for as long as a year after childbirth, is a common, underdiagnosed outcome of both normal and complicated pregnancies.¹ Peripartum depression, which includes PPD and depression during pregnancy, occurs in approximately 10% of pregnancies.^2,3 When depression first appears in the postpartum period, most women develop symptoms in the first month after delivery (54% of cases) or in the next 2 to 4 months (40%).⁴

The most significant risk factor for PPD is previous depression, peripartum or otherwise.^1,4-6 Other common risk factors include major life events or stressors during or after pregnancy, domestic violence, poor social support, and preterm birth or an infant admission to the neonatal intensive care unit.^1,7 Women with a self-perceived negative birth experience are also likely to experience PPD.⁸ PPD can be associated with significant morbidity and mortality, with suicide a more common cause of maternal mortality than either hemorrhage or hypertensive disorders of pregnancy.⁹

Women with postpartum anemia and low ferritin stores are more prone to depression than are those with normal levels.

Early diagnosis and intervention are crucial to improving patient outcomes. Women with PPD initiate breastfeeding at lower rates and continue for shorter durations.¹⁰ PPD also affects maternal–infant bonding; may adversely affect an infant’s social, cognitive, and language development; and may lead to attachment disorders of infancy.^11,12 In severe cases, it can lead to failure to thrive or infanticide.¹¹

When to screen. The US Preventive Services Task Force (USPSTF) recommends clinicians screen for depression in pregnant and postpartum women (Grade B^a) and for women at increased risk, provide or refer to counseling interventions (Grade B^a).^13,14 The American College of Obstetricians and Gynecologists (ACOG) recommends screening at least once in the postpartum period.¹⁵ Repeat screening at follow-up in the later postpartum period increases the likelihood of diagnosis.¹⁶ Screening for PPD as part of well-child care improves maternal outcomes, and the American Academy of Pediatrics recommends screening at the 1-, 2-, 4-, and 6-month visits.^11,17 These screens are separately billable. Family physicians are uniquely suited to screening at both well-child and postpartum visits, as many women share a medical home with their child, and those who do not are equally willing to receive medical advice from their child’s physician.¹⁸

CASE

Erica S*, age 22, has intermittent asthma and presents to your clinic to discuss refills of her albuterol inhaler. Two years ago, she was hospitalized for a severe asthma exacerbation because she was unable to afford medications. Since then, her asthma has generally been well controlled, and she needs to use albuterol only 1 or 2 times per month. Ms. S says she has no morning chest tightness or nocturnal coughing, but she does experience increased wheezing and shortness of breath with activity.

What would you recommend? Would your recommendation differ if she had persistent asthma?

* The patient’s name has been changed to protect her identity .

As of 2020, more than 20 million adults and 4 million children younger than 18 years of age in the United States were living with asthma.¹ In 2019 alone, there were more than 1.8 million asthma-related emergency department visits for adults, and more than 790,000 asthma-related emergency department visits for children. Asthma caused more than 4000 deaths in the United States in 2020.¹ Given the scale of the burden of asthma, it is not surprising that approximately 60% of all asthma visits occur in primary care settings,² making it essential that primary care physicians stay abreast of recent developments in asthma diagnosis and management.

Since 1991, the major guidance on best practices for asthma management in the United States has been provided by the National Heart, Lung, and Blood Institute (NHLBI)’s National Asthma Education and Prevention Program (NAEPP). Its last major update on asthma was released in 2007 as the Expert Panel Report 3: Guidelines for the Diagnosis and Management of Asthma (EPR-3).³ Since that time, there has been significant progress in our understanding of asthma as a complex spectrum of phenotypes, which has advanced our knowledge of pathophysiology and helped refine treatment. In contrast to the NAEPP, the Global Initiative for Asthma (GINA) has published annual updates on asthma management incorporating up-to-date information.⁴ In response to the continuously evolving body of knowledge on asthma, the NAEPP Coordinating Committee Expert Panel Working Group published the 2020 Focused Updates to the Asthma Management Guidelines.⁵

Given the vast resources available on asthma, our purpose in this article is not to provide a comprehensive review of the stepwise approach to asthma management, but instead to summarize the major points presented in the 2020 Focused Updates and how these compare and contrast with the latest guidance from GINA.

A heterogeneous disease

Asthma is a chronic respiratory disease characterized by both variable symptoms and airflow limitation that change over time, often in response to external triggers such as exercise, allergens, and viral respiratory infections. Common symptoms include wheezing, cough, chest tightness, and shortness of breath. Despite the common symptomatology, asthma is a heterogeneous disease with several recognizable phenotypes including allergic, nonallergic, and asthma with persistent airflow limitation.

Continue to: The airflow limitation...

The airflow limitation in asthma occurs through both airway hyperresponsiveness to external stimuli and chronic airway inflammation. Airway constriction is regulated by nerves to the smooth muscles of the airway. Beta-2 nerve receptors have long been the target of asthma therapy with both short-acting beta-2 agonists (SABAs) as rescue treatment and long-acting beta-2 agonists (LABAs) as maintenance therapy.^3,4 However, there is increasing evidence that cholinergic nerves also have a role in airway regulation in asthma, and long-acting muscarinic antagonists (LAMAs) have recently shown benefit as add-on therapy in some types of asthma.^4-6 Inhaled corticosteroids (ICSs) have long held an important role in reducing airway inflammation, especially in the setting of allergic or eosinophilic inflammation.^3-5

Spirometry is essential to asthma Dx—but what about FeNO?

The mainstay of asthma diagnosis is confirming both a history of variable respiratory symptoms and variable expiratory airflow limitation exhibited by spirometry. Obstruction is defined as a reduced forced expiratory volume in 1 second (FEV₁) and as a decreased ratio of FEV₁ over forced vital capacity (FVC) based on predicted values. An increase of at least 12% in FEV₁ post bronchodilator use indicates asthma for adolescents and adults.

A fractional exhaled nitric oxide level > 50 ppb makes eosinophilic inflammation and treatment response to an inhaled corticosteroid more likely.

More recently, studies have examined the role of fractional exhaled nitric oxide (FeNO) in the diagnosis of asthma. The 2020 Focused Updates report states that FeNO may be useful when the diagnosis of asthma is uncertain using initial history, physical exam, and spirometry findings, or when spirometry cannot be performed reliably.⁵ Levels of FeNO > 50 ppb make eosinophilic inflammation and treatment response to an ICS more likely. FeNO levels < 25 ppb make inflammatory asthma less likely and should prompt a search for an alternate diagnosis.⁵ For patients with FeNO of 25 to 50 ppb, more detailed clinical context is needed. In contrast, the 2022 GINA updates conclude that FeNO is not yet an established diagnostic tool for asthma.⁴

Management

When to start and adjust an ICS

ICSs continue to be the primary controller treatment for patients with asthma. However, the NAEPP and GINA have provided different guidance on how to initiate step therapy (TABLE^3-5). NAEPP focuses on severity classification, while GINA recommends treatment initiation based on presenting symptoms. Since both guidelines recommend early ­follow-up and adjustment of therapy according to level of control, this difference becomes less apparent in ongoing care.

A more fundamental difference is seen in the recommended therapies for each step (TABLE^3-5). Whereas the 2020 Focused Updates prefers a SABA as needed in step 1, GINA favors a low-dose combination of ICS-formoterol as needed. The GINA recommendation is driven by supportive evidence for early initiation of low-dose ICS in any patient with asthma for greater improvement in lung function. This also addresses concerns that overuse of as-needed SABAs may increase the risk for severe exacerbations. Evidence also indicates that the risk for asthma-­related death and urgent asthma-related health care increases when a patient takes a SABA as needed as monotherapy compared with ICS therapy, even with good symptom control.^7,8

Continue to: Dosing of an ICS

Dosing of an ICS is based on step therapy regardless of the guideline used and is given at a total daily amount—low, medium, and high—for each age group. When initiating an ICS, consider differences between available treatment options (eg, cost, administration technique, likely patient adherence, patient preferences) and employ shared decision-making strategies. Dosing may need to be limited depending on the commercially available product, especially when used in combination with a LABA. However, as GINA emphasizes, a low-dose ICS provides the most clinical benefit. A high-dose ICS is needed by very few patients and is associated with greater risk for local and systemic adverse effects, such as adrenal suppression. With these considerations, both guidelines recommend using the lowest effective ICS dose and stepping up and down according to the patient’s comfort level.

Give an ICS time to work. Although an ICS can begin to reduce inflammation within days of initiation, the full benefit may be evident only after 2 to 3 months.⁴ Once the patient’s asthma is well controlled for 3 months, stepping down the dose can be considered and approached carefully. Complete cessation of ICSs is associated with significantly higher risk for exacerbations. Therefore, a general recommendation is to step down an ICS by 50% or reduce ICS-LABA from twice-daily administration to once daily. Risk for exacerbation after step-down therapy is heightened if the patient has a history of exacerbation or an emergency department visit in the past 12 months, a low baseline FEV₁, or a loss of control during a dose reduction (ie, airway hyperresponsiveness and sputum eosinophilia).

Weigh the utility of FeNO measurement. The 2020 Focused Updates also recommend considering FeNO measurement to guide treatment choice and monitoring, although this is based on overall low certainty of evidence.⁵ GINA affirms the mixed evidence for FeNO, stating that while a few studies have shown significantly reduced exacerbations among children, adolescents, and pregnant women with FeNO-guided treatment, other studies have shown no significant difference in exacerbations.^4,9-15 At this time, the role for FeNO in asthma management remains inconclusive, and access to it is limited across primary care settings.

Inhaled corticosteroids can begin to reduce inflammation within days, but the full benefit may be evident only after 2 to 3 months.

When assessing response to ICS therapy (and before stepping up therapy), consider patient adherence, inhaler technique, whether allergen exposure is persistent, and possible comorbidities. Inhaler technique can be especially challenging, as each inhaler varies in appearance and operation. Employ patient education strategies (eg, videos, demonstration, teach-back methods). If stepping up therapy is indicated, adding a LABA is recommended over increasing the ICS dose. Since asthma is variable, stepping up therapy can be tried and reassessed in 2 to 3 months.

SMART is preferred

Single maintenance and reliever therapy (SMART) with ICS-formoterol, used as needed, is the preferred therapy for steps 3 and 4 in both GINA recommendations and the 2020 Focused Updates (TABLE^3-5). GINA also prefers SMART for step 5. The recommended SMART combination that has been studied contains budesonide (or beclomethasone, not available in combination in the United States) for the ICS and formoterol for the LABA in a single inhaler that is used both daily for control and as needed for rescue therapy.

Continue to: Other ICS-formoterol...

Other ICS-formoterol or ICS-LABA combinations can be considered for controller therapy, especially those described in the NAEPP and GINA alternative step therapy recommendations. However, SMART has been more effective than other combinations in reducing exacerbations and provides similar or better levels of control at lower average ICS doses (compared with ICS-LABA with SABA or ICS with SABA) for adolescent and adult patients.^3,4 As patients use greater amounts of ICS-formoterol during episodes of increased symptoms, this additional ICS may augment the anti-inflammatory effects. SMART may also improve adherence, especially among those who confuse multiple inhalers.

SMART is also recommended for use in children. Specifically, from the 2020 Focused Updates, any patient ≥ 4 years of age with a severe exacerbation in the past year is a good SMART candidate. Also consider SMART before higher-dose ICS-LABA and SABA as needed. Additional benefits in this younger patient population are fewer medical visits or less systemic corticosteroid use with improved control and quality of life.

Caveats. Patients who have a difficult time recognizing symptoms may not be good candidates for SMART, due to the potential for taking higher or lower ICS doses than necessary.

SMART specifically refers to formoterol combinations that produce bronchodilation within 1 to 3 minutes.¹⁶ For example, the SMART strategy is not recommended for patients using ICS-salmeterol as controller therapy.

Although guideline supported, SMART options are not approved by the US Food and Drug Administration for use as reliever therapy.

Continue to: With the single combination...

With the single combination inhaler, consider the dosing limits of formoterol. The maximum daily amount of formoterol for ­adolescents and adults is 54 μg (12 puffs) delivered with the budesonide-formoterol metered dose inhaler. When using SMART as reliever therapy, the low-dose ICS-­formoterol recommendation remains. However, depending on insurance coverage, a 1-month supply of ­ICS-formoterol may not be sufficient for additional reliever therapy use.

The role of LAMAs as add-on therapy

Bronchiolar smooth muscle tone is mediated by complex mechanisms that include cholinergic stimulation at muscarinic (M3) receptors.¹⁷ LAMAs, a mainstay in the management of chronic obstructive pulmonary disease (COPD), are likely to be effective in reducing asthma exacerbations and the need for oral steroids. When patients have not achieved control at step 4 of asthma therapy, both the 2020 Focused Updates and GINA now recommend considering a LAMA (eg, tiotropium) as add-on therapy for patients > 12 years of age already taking medium-dose ICS-LABA for modest improvements in lung function and reductions in severe exacerbations. GINA recommendations also now include a LAMA as add-on treatment for those ages 6 to 11 years, as some evidence supports the use in school-aged children.¹⁸ It is important to note that LAMAs should not replace a LABA for treatment, as the ICS-LABA combination is likely more effective than ICS-LAMA.

Addressing asthma-COPD overlap

Asthma and COPD are frequently and frustratingly intertwined without clear demarcation. This tends to occur as patients age and chronic lung changes appear from longstanding asthma. However, it is important to distinguish between these conditions, because there are clearly delineated treatments for each that can improve outcomes.

The priority in addressing asthma-COPD overlap (ACO) is to evaluate symptoms and determine if asthma or COPD is predominant.¹⁹ This includes establishing patient age at which symptoms began, variation and triggers of symptoms, and history of exposures to smoke/environmental respiratory toxins. Age 40 years is often used as the tipping point at which symptom onset favors a diagnosis of COPD. Serial spirometry may also be used to evaluate lung function over time and persistence of disease. If a firm diagnosis is evasive, consider a referral to a pulmonary specialist for further testing.

The priority in addressing asthma-COPD overlap is to evaluate symptoms and determine if asthma or COPD is predominant.

Choosing to use an ICS or LAMA depends on which underlying disorder is more likely. While early COPD management includes LAMA + LABA, the addition of an ICS is reserved for more severe disease. High-dose ICSs, particularly fluticasone, should be limited in COPD due to an increased risk for pneumonia. For asthma or ACO, the addition of an ICS is critical and prioritized to reduce airway inflammation and risk for exacerbations and death. While a LAMA is likely useful earlier in ACO, it is not used until step 5 of asthma therapy. Given the complexities of ACO treatment, further research is needed to provide adequate guidance.

CASE

For Ms. S, you would be wise to use an ICS-formoterol combination for as-needed symptom relief. If symptoms were more persistent, you could consider recommending the ICS-­formoterol inhaler as SMART therapy, with regular doses taken twice daily and extra ­doses taken as needed.

Since both guidelines recommend early ­follow-up and adjustment of therapy according to level of control, this difference becomes less apparent in ongoing care.

A more fundamental difference is seen in the recommended therapies for each step (TABLE^3-5). Whereas the 2020 Focused Updates prefers a SABA as needed in step 1, GINA favors a low-dose combination of ICS-formoterol as needed. The GINA recommendation is driven by supportive evidence for early initiation of low-dose ICS in any patient with asthma for greater improvement in lung function. This also addresses concerns that overuse of as-needed SABAs may increase the risk for severe exacerbations. Evidence also indicates that the risk for asthma-­related death and urgent asthma-related health care increases when a patient takes a SABA as needed as monotherapy compared with ICS therapy, even with good symptom control.^7,8

Continue to: Dosing of an ICS

Dosing of an ICS is based on step therapy regardless of the guideline used and is given at a total daily amount—low, medium, and high—for each age group. When initiating an ICS, consider differences between available treatment options (eg, cost, administration technique, likely patient adherence, patient preferences) and employ shared decision-making strategies. Dosing may need to be limited depending on the commercially available product, especially when used in combination with a LABA. However, as GINA emphasizes, a low-dose ICS provides the most clinical benefit. A high-dose ICS is needed by very few patients and is associated with greater risk for local and systemic adverse effects, such as adrenal suppression. With these considerations, both guidelines recommend using the lowest effective ICS dose and stepping up and down according to the patient’s comfort level.

Give an ICS time to work. Although an ICS can begin to reduce inflammation within days of initiation, the full benefit may be evident only after 2 to 3 months.⁴ Once the patient’s asthma is well controlled for 3 months, stepping down the dose can be considered and approached carefully. Complete cessation of ICSs is associated with significantly higher risk for exacerbations. Therefore, a general recommendation is to step down an ICS by 50% or reduce ICS-LABA from twice-daily administration to once daily. Risk for exacerbation after step-down therapy is heightened if the patient has a history of exacerbation or an emergency department visit in the past 12 months, a low baseline FEV₁, or a loss of control during a dose reduction (ie, airway hyperresponsiveness and sputum eosinophilia).

Weigh the utility of FeNO measurement. The 2020 Focused Updates also recommend considering FeNO measurement to guide treatment choice and monitoring, although this is based on overall low certainty of evidence.⁵ GINA affirms the mixed evidence for FeNO, stating that while a few studies have shown significantly reduced exacerbations among children, adolescents, and pregnant women with FeNO-guided treatment, other studies have shown no significant difference in exacerbations.^4,9-15 At this time, the role for FeNO in asthma management remains inconclusive, and access to it is limited across primary care settings.

Inhaled corticosteroids can begin to reduce inflammation within days, but the full benefit may be evident only after 2 to 3 months.

When assessing response to ICS therapy (and before stepping up therapy), consider patient adherence, inhaler technique, whether allergen exposure is persistent, and possible comorbidities. Inhaler technique can be especially challenging, as each inhaler varies in appearance and operation. Employ patient education strategies (eg, videos, demonstration, teach-back methods). If stepping up therapy is indicated, adding a LABA is recommended over increasing the ICS dose. Since asthma is variable, stepping up therapy can be tried and reassessed in 2 to 3 months.

SMART is preferred

Single maintenance and reliever therapy (SMART) with ICS-formoterol, used as needed, is the preferred therapy for steps 3 and 4 in both GINA recommendations and the 2020 Focused Updates (TABLE^3-5). GINA also prefers SMART for step 5. The recommended SMART combination that has been studied contains budesonide (or beclomethasone, not available in combination in the United States) for the ICS and formoterol for the LABA in a single inhaler that is used both daily for control and as needed for rescue therapy.

Continue to: Other ICS-formoterol...

Other ICS-formoterol or ICS-LABA combinations can be considered for controller therapy, especially those described in the NAEPP and GINA alternative step therapy recommendations. However, SMART has been more effective than other combinations in reducing exacerbations and provides similar or better levels of control at lower average ICS doses (compared with ICS-LABA with SABA or ICS with SABA) for adolescent and adult patients.^3,4 As patients use greater amounts of ICS-formoterol during episodes of increased symptoms, this additional ICS may augment the anti-inflammatory effects. SMART may also improve adherence, especially among those who confuse multiple inhalers.

SMART is also recommended for use in children. Specifically, from the 2020 Focused Updates, any patient ≥ 4 years of age with a severe exacerbation in the past year is a good SMART candidate. Also consider SMART before higher-dose ICS-LABA and SABA as needed. Additional benefits in this younger patient population are fewer medical visits or less systemic corticosteroid use with improved control and quality of life.

Caveats. Patients who have a difficult time recognizing symptoms may not be good candidates for SMART, due to the potential for taking higher or lower ICS doses than necessary.

SMART specifically refers to formoterol combinations that produce bronchodilation within 1 to 3 minutes.¹⁶ For example, the SMART strategy is not recommended for patients using ICS-salmeterol as controller therapy.

Although guideline supported, SMART options are not approved by the US Food and Drug Administration for use as reliever therapy.

Continue to: With the single combination...

With the single combination inhaler, consider the dosing limits of formoterol. The maximum daily amount of formoterol for ­adolescents and adults is 54 μg (12 puffs) delivered with the budesonide-formoterol metered dose inhaler. When using SMART as reliever therapy, the low-dose ICS-­formoterol recommendation remains. However, depending on insurance coverage, a 1-month supply of ­ICS-formoterol may not be sufficient for additional reliever therapy use.

The role of LAMAs as add-on therapy

Bronchiolar smooth muscle tone is mediated by complex mechanisms that include cholinergic stimulation at muscarinic (M3) receptors.¹⁷ LAMAs, a mainstay in the management of chronic obstructive pulmonary disease (COPD), are likely to be effective in reducing asthma exacerbations and the need for oral steroids. When patients have not achieved control at step 4 of asthma therapy, both the 2020 Focused Updates and GINA now recommend considering a LAMA (eg, tiotropium) as add-on therapy for patients > 12 years of age already taking medium-dose ICS-LABA for modest improvements in lung function and reductions in severe exacerbations. GINA recommendations also now include a LAMA as add-on treatment for those ages 6 to 11 years, as some evidence supports the use in school-aged children.¹⁸ It is important to note that LAMAs should not replace a LABA for treatment, as the ICS-LABA combination is likely more effective than ICS-LAMA.

Addressing asthma-COPD overlap

Asthma and COPD are frequently and frustratingly intertwined without clear demarcation. This tends to occur as patients age and chronic lung changes appear from longstanding asthma. However, it is important to distinguish between these conditions, because there are clearly delineated treatments for each that can improve outcomes.

The priority in addressing asthma-COPD overlap (ACO) is to evaluate symptoms and determine if asthma or COPD is predominant.¹⁹ This includes establishing patient age at which symptoms began, variation and triggers of symptoms, and history of exposures to smoke/environmental respiratory toxins. Age 40 years is often used as the tipping point at which symptom onset favors a diagnosis of COPD. Serial spirometry may also be used to evaluate lung function over time and persistence of disease. If a firm diagnosis is evasive, consider a referral to a pulmonary specialist for further testing.

The priority in addressing asthma-COPD overlap is to evaluate symptoms and determine if asthma or COPD is predominant.

Choosing to use an ICS or LAMA depends on which underlying disorder is more likely. While early COPD management includes LAMA + LABA, the addition of an ICS is reserved for more severe disease. High-dose ICSs, particularly fluticasone, should be limited in COPD due to an increased risk for pneumonia. For asthma or ACO, the addition of an ICS is critical and prioritized to reduce airway inflammation and risk for exacerbations and death. While a LAMA is likely useful earlier in ACO, it is not used until step 5 of asthma therapy. Given the complexities of ACO treatment, further research is needed to provide adequate guidance.

CASE

For Ms. S, you would be wise to use an ICS-formoterol combination for as-needed symptom relief. If symptoms were more persistent, you could consider recommending the ICS-­formoterol inhaler as SMART therapy, with regular doses taken twice daily and extra ­doses taken as needed.

CASE

Erica S*, age 22, has intermittent asthma and presents to your clinic to discuss refills of her albuterol inhaler. Two years ago, she was hospitalized for a severe asthma exacerbation because she was unable to afford medications. Since then, her asthma has generally been well controlled, and she needs to use albuterol only 1 or 2 times per month. Ms. S says she has no morning chest tightness or nocturnal coughing, but she does experience increased wheezing and shortness of breath with activity.

What would you recommend? Would your recommendation differ if she had persistent asthma?

* The patient’s name has been changed to protect her identity .

As of 2020, more than 20 million adults and 4 million children younger than 18 years of age in the United States were living with asthma.¹ In 2019 alone, there were more than 1.8 million asthma-related emergency department visits for adults, and more than 790,000 asthma-related emergency department visits for children. Asthma caused more than 4000 deaths in the United States in 2020.¹ Given the scale of the burden of asthma, it is not surprising that approximately 60% of all asthma visits occur in primary care settings,² making it essential that primary care physicians stay abreast of recent developments in asthma diagnosis and management.

Since 1991, the major guidance on best practices for asthma management in the United States has been provided by the National Heart, Lung, and Blood Institute (NHLBI)’s National Asthma Education and Prevention Program (NAEPP). Its last major update on asthma was released in 2007 as the Expert Panel Report 3: Guidelines for the Diagnosis and Management of Asthma (EPR-3).³ Since that time, there has been significant progress in our understanding of asthma as a complex spectrum of phenotypes, which has advanced our knowledge of pathophysiology and helped refine treatment. In contrast to the NAEPP, the Global Initiative for Asthma (GINA) has published annual updates on asthma management incorporating up-to-date information.⁴ In response to the continuously evolving body of knowledge on asthma, the NAEPP Coordinating Committee Expert Panel Working Group published the 2020 Focused Updates to the Asthma Management Guidelines.⁵

Given the vast resources available on asthma, our purpose in this article is not to provide a comprehensive review of the stepwise approach to asthma management, but instead to summarize the major points presented in the 2020 Focused Updates and how these compare and contrast with the latest guidance from GINA.

A heterogeneous disease

Asthma is a chronic respiratory disease characterized by both variable symptoms and airflow limitation that change over time, often in response to external triggers such as exercise, allergens, and viral respiratory infections. Common symptoms include wheezing, cough, chest tightness, and shortness of breath. Despite the common symptomatology, asthma is a heterogeneous disease with several recognizable phenotypes including allergic, nonallergic, and asthma with persistent airflow limitation.

Continue to: The airflow limitation...

The airflow limitation in asthma occurs through both airway hyperresponsiveness to external stimuli and chronic airway inflammation. Airway constriction is regulated by nerves to the smooth muscles of the airway. Beta-2 nerve receptors have long been the target of asthma therapy with both short-acting beta-2 agonists (SABAs) as rescue treatment and long-acting beta-2 agonists (LABAs) as maintenance therapy.^3,4 However, there is increasing evidence that cholinergic nerves also have a role in airway regulation in asthma, and long-acting muscarinic antagonists (LAMAs) have recently shown benefit as add-on therapy in some types of asthma.^4-6 Inhaled corticosteroids (ICSs) have long held an important role in reducing airway inflammation, especially in the setting of allergic or eosinophilic inflammation.^3-5

Spirometry is essential to asthma Dx—but what about FeNO?

The mainstay of asthma diagnosis is confirming both a history of variable respiratory symptoms and variable expiratory airflow limitation exhibited by spirometry. Obstruction is defined as a reduced forced expiratory volume in 1 second (FEV₁) and as a decreased ratio of FEV₁ over forced vital capacity (FVC) based on predicted values. An increase of at least 12% in FEV₁ post bronchodilator use indicates asthma for adolescents and adults.

A fractional exhaled nitric oxide level > 50 ppb makes eosinophilic inflammation and treatment response to an inhaled corticosteroid more likely.

More recently, studies have examined the role of fractional exhaled nitric oxide (FeNO) in the diagnosis of asthma. The 2020 Focused Updates report states that FeNO may be useful when the diagnosis of asthma is uncertain using initial history, physical exam, and spirometry findings, or when spirometry cannot be performed reliably.⁵ Levels of FeNO > 50 ppb make eosinophilic inflammation and treatment response to an ICS more likely. FeNO levels < 25 ppb make inflammatory asthma less likely and should prompt a search for an alternate diagnosis.⁵ For patients with FeNO of 25 to 50 ppb, more detailed clinical context is needed. In contrast, the 2022 GINA updates conclude that FeNO is not yet an established diagnostic tool for asthma.⁴

Management

When to start and adjust an ICS

ICSs continue to be the primary controller treatment for patients with asthma. However, the NAEPP and GINA have provided different guidance on how to initiate step therapy (TABLE^3-5). NAEPP focuses on severity classification, while GINA recommends treatment initiation based on presenting symptoms. Since both guidelines recommend early ­follow-up and adjustment of therapy according to level of control, this difference becomes less apparent in ongoing care.

In 2019, a New York Times opinion piece titled, “The Big IVF Add-On Racket – This is no way to treat patients desperate for a baby”¹ alleged exploitation of infertility patients based on a Fertility and Sterility article, “Do à la carte menus serve infertility patients? The ethics and regulation of in vitro fertility add-ons.”² The desperation of infertility patients combined with their financial burden, caused by inconsistent insurance coverage, has resulted in a perfect storm of frustration and overzealous recommendations for a successful outcome. Since the inception of in vitro fertilization (IVF) itself, infertility patients have been subjected to many unproven tests and procedures that enter the mainstream of care before unequivocal efficacy and safety have been shown.

From ovarian stimulation with intrauterine insemination (IUI) or IVF along with intracytoplasmic sperm injection (ICSI), assisted hatching, and preimplantation genetic testing for aneuploidy (PGT-A), a multitude of options with varying success can overwhelm fertility patients as they walk the tightrope of wanting “the kitchen sink” of treatment while experiencing sticker shock. This month’s article examines the top 10 infertility add-ons that have yet to be shown to improve pregnancy outcomes.

1. Blood testing: Prolactin and FSH

In a woman with ovulatory monthly menstrual cycles, a serum prolactin level provides no elucidation of the cause of infertility. If obtained following ovulation, prolactin can often be physiologically elevated, thereby compelling a repeat blood level, which is ideally performed during the early proliferative phase. False elevations of prolactin can be caused by an early morning blood sample, eating, and stress – which may result from worry caused by having to repeat the unnecessary initial blood test!

Follicle-stimulating hormone (FSH) was a first-line hormone test to assess for ovarian age. For nearly 15 years now, FSH has been replaced by anti-Müllerian hormone as a more reliable and earlier test for diminished ovarian reserve. However, FSH is still the hormone test of choice to diagnose primary ovarian insufficiency. Note that the use of ovarian age testing in a woman without infertility can result in both unnecessary patient anxiety and additional testing.
 

2. Endometrial scratch

The concept was understandable, that is, induce endometrial trauma by a biopsy or “scratch,” that results in an inflammatory and immunologic response to increase implantation. Endometrial sampling was recommended to be performed during the month prior to the embryo transfer cycle. While the procedure is brief, the pain response of women varies from minimal to severe. Unfortunately, a randomized controlled trial of over 1,300 patients did not show any improvement in the IVF live birth rate from the scratch procedure.³

3. Diagnostic laparoscopy

In years past, a diagnosis of unexplained infertility was not accepted until a laparoscopy was performed that revealed a normal pelvis. This approach subjected many women to an unindicated and a potentially risky surgery that has not shown benefit. The American Society for Reproductive Medicine’s ReproductiveFacts.org website states: “Routine diagnostic laparoscopy should not be performed unless there is a suspicion of pelvic pathology based on clinical history, an abnormal pelvic exam, or abnormalities identified with less invasive testing. In patients with a normal hysterosalpingogram or the presence of a unilaterally patent tube, diagnostic laparoscopy typically will not change the initial recommendation for treatment.”

4. Prescribing clomiphene citrate without IUI

Ovulation dysfunction is found in 40% of female factors for fertility. Provided testing reveals a reasonably normal sperm analysis and hysterosalpingogram, ovulation induction medication with ultrasound monitoring along with an hCG trigger is appropriate. In women who ovulate with unexplained infertility and/or mild male factor, the use of clomiphene citrate or letrozole with timed intercourse is often prescribed, particularly in clinics when IUI preparation is not available. Unfortunately, without including IUI, the use of oral ovarian stimulation has been shown by good evidence to be no more effective than natural cycle attempts at conception.⁴

5. Thrombophilia testing

Recurrent miscarriage, defined by the spontaneous loss of two or more pregnancies (often during the first trimester but may include up to 20 weeks estimated gestational age), has remained an ill-defined problem that lacks a consensus on the most optimal evaluation and treatment. In 2006, an international consensus statement provided guidance on laboratory testing for antiphospholipid syndrome limited to lupus anticoagulant, anticardiolipin IgG and IgM, and IgG and IgM anti–beta₂-glycoprotein I assays.⁵ ASRM does not recommend additional thrombophilia tests as they are unproven causative factors of recurrent miscarriage.

6. Screening hysteroscopy

A standard infertility evaluation includes ovulation testing, assessment of fallopian tube patency, and a sperm analysis. In a subfertile women with a normal ultrasound or hysterosalpingogram in the basic fertility work‐up, a Cochrane data review concluded there is no definitive evidence for improved outcome with a screening hysteroscopy prior to IUI or IVF.^6,7 Two large trials included in the Cochrane review, confirmed similar live birth rates whether or not hysteroscopy was performed before IVF. There may value in screening patients with recurrent implantation failure.

7. PGT-A for all

As the efficacy of the first generation of embryo preimplantation genetic testing, i.e., FISH (fluorescence in situ hybridization) was disproven, so has the same result been determined for PGT-A, specifically in women younger than 35.⁸ In an elegant randomized prospective trial, Munne and colleagues showed no improvement in the ongoing pregnancy rate (OPR) of study patients of all ages who were enrolled with the intention to treat. However, a subanalysis of patients aged 35-40 who completed the protocol did show an improved OPR and lower miscarriage rate per embryo transfer. While there is no evidence to support improved outcomes with the universal application of PGT-A, there may be some benefit in women older than 35 as well as in certain individual patient circumstances.

8. ICSI for nonmale factor infertility; assisted hatching

In an effort to reduce the risk of fertilization failure, programs have broadened the use of ICSI to nonmale factor infertility. While it has been used in PGT to reduce the risk of DNA contamination, particularly in PGT-M (monogenic disorder) and PGT-SR (structural rearrangement) cases, ICSI has not been shown to improve outcomes when there is a normal sperm analysis.⁹ During IVF embryo development, assisted hatching involves the thinning and/or opening of the zona pellucida either by chemical, mechanical, or laser means around the embryo before transfer with the intention of facilitating implantation. The routine use of assisted hatching is not recommended based on the lack of increase in live birth rates and because it may increase multiple pregnancy and monozygotic twinning rates.¹⁰

9. Acupuncture

Four meta-analyses showed no evidence of the overall benefit of acupuncture for improving live birth rates regardless of whether acupuncture was performed around the time of oocyte retrieval or around the day of embryo transfer. Consequently, acupuncture cannot be recommended routinely to improve IVF outcomes.¹¹

10. Immunologic tests/treatments

Given the “foreign” genetic nature of a fetus, attempts to suppress the maternal immunologic response to sustain the pregnancy have been made for decades, especially for recurrent miscarriage and recurrent implantation failure with IVF. Testing has included natural killer (NK) cells, human leukocyte antigen (HLA) genotypes, and cytokines. While NK cells can be examined by endometrial biopsy, levels fluctuate based on the cycle phase, and no correlation between peripheral blood testing and uterine NK cell levels has been shown. Further, no consensus has been reached on reliable normal reference ranges in uterine NK cells.¹²

Several treatments have been proposed to somehow modulate the immune system during the implantation process thereby improving implantation and live birth, including lipid emulsion (intralipid) infusion, intravenous immunoglobulin, leukocyte immunization therapy, tacrolimus, anti–tumor necrosis factor agents, and granulocyte colony-stimulating factor. A recent systematic review and meta-analysis cited low-quality studies and did not recommend the use of any of these immune treatments.¹³ Further, immunomodulation has many known side effects, some of which are serious (including hepatosplenomegaly, thrombocytopenia, leukopenia, renal failure, thromboembolism, and anaphylactic reactions). Excluding women with autoimmune disease, taking glucocorticoids or other immune treatments to improve fertility has not been proven.¹³

Conclusion

To quote the New York Times opinion piece, “IVF remains an under-regulated arena, and entrepreneurial doctors and pharmaceutical and life science companies are eager to find new ways to cash in on a growing global market that is projected to be as large as $40 billion by 2024.” While this bold statement compels a huge “Ouch!”, it reminds us of our obligation to provide evidence-based medicine and to include emotional and financial harm to our oath of Primum non nocere.

This month’s article examines the top 10 infertility add-ons that have yet to be shown to improve pregnancy outcomes.

1. Blood testing: Prolactin and FSH

In a woman with ovulatory monthly menstrual cycles, a serum prolactin level provides no elucidation of the cause of infertility. If obtained following ovulation, prolactin can often be physiologically elevated, thereby compelling a repeat blood level, which is ideally performed during the early proliferative phase. False elevations of prolactin can be caused by an early morning blood sample, eating, and stress – which may result from worry caused by having to repeat the unnecessary initial blood test!

Follicle-stimulating hormone (FSH) was a first-line hormone test to assess for ovarian age. For nearly 15 years now, FSH has been replaced by anti-Müllerian hormone as a more reliable and earlier test for diminished ovarian reserve. However, FSH is still the hormone test of choice to diagnose primary ovarian insufficiency. Note that the use of ovarian age testing in a woman without infertility can result in both unnecessary patient anxiety and additional testing.
 

2. Endometrial scratch

The concept was understandable, that is, induce endometrial trauma by a biopsy or “scratch,” that results in an inflammatory and immunologic response to increase implantation. Endometrial sampling was recommended to be performed during the month prior to the embryo transfer cycle. While the procedure is brief, the pain response of women varies from minimal to severe. Unfortunately, a randomized controlled trial of over 1,300 patients did not show any improvement in the IVF live birth rate from the scratch procedure.³

3. Diagnostic laparoscopy

In years past, a diagnosis of unexplained infertility was not accepted until a laparoscopy was performed that revealed a normal pelvis. This approach subjected many women to an unindicated and a potentially risky surgery that has not shown benefit. The American Society for Reproductive Medicine’s ReproductiveFacts.org website states: “Routine diagnostic laparoscopy should not be performed unless there is a suspicion of pelvic pathology based on clinical history, an abnormal pelvic exam, or abnormalities identified with less invasive testing. In patients with a normal hysterosalpingogram or the presence of a unilaterally patent tube, diagnostic laparoscopy typically will not change the initial recommendation for treatment.”

4. Prescribing clomiphene citrate without IUI

Ovulation dysfunction is found in 40% of female factors for fertility. Provided testing reveals a reasonably normal sperm analysis and hysterosalpingogram, ovulation induction medication with ultrasound monitoring along with an hCG trigger is appropriate. In women who ovulate with unexplained infertility and/or mild male factor, the use of clomiphene citrate or letrozole with timed intercourse is often prescribed, particularly in clinics when IUI preparation is not available. Unfortunately, without including IUI, the use of oral ovarian stimulation has been shown by good evidence to be no more effective than natural cycle attempts at conception.⁴

5. Thrombophilia testing

Recurrent miscarriage, defined by the spontaneous loss of two or more pregnancies (often during the first trimester but may include up to 20 weeks estimated gestational age), has remained an ill-defined problem that lacks a consensus on the most optimal evaluation and treatment. In 2006, an international consensus statement provided guidance on laboratory testing for antiphospholipid syndrome limited to lupus anticoagulant, anticardiolipin IgG and IgM, and IgG and IgM anti–beta₂-glycoprotein I assays.⁵ ASRM does not recommend additional thrombophilia tests as they are unproven causative factors of recurrent miscarriage.

6. Screening hysteroscopy

A standard infertility evaluation includes ovulation testing, assessment of fallopian tube patency, and a sperm analysis. In a subfertile women with a normal ultrasound or hysterosalpingogram in the basic fertility work‐up, a Cochrane data review concluded there is no definitive evidence for improved outcome with a screening hysteroscopy prior to IUI or IVF.^6,7 Two large trials included in the Cochrane review, confirmed similar live birth rates whether or not hysteroscopy was performed before IVF. There may value in screening patients with recurrent implantation failure.

7. PGT-A for all

As the efficacy of the first generation of embryo preimplantation genetic testing, i.e., FISH (fluorescence in situ hybridization) was disproven, so has the same result been determined for PGT-A, specifically in women younger than 35.⁸ In an elegant randomized prospective trial, Munne and colleagues showed no improvement in the ongoing pregnancy rate (OPR) of study patients of all ages who were enrolled with the intention to treat. However, a subanalysis of patients aged 35-40 who completed the protocol did show an improved OPR and lower miscarriage rate per embryo transfer. While there is no evidence to support improved outcomes with the universal application of PGT-A, there may be some benefit in women older than 35 as well as in certain individual patient circumstances.

8. ICSI for nonmale factor infertility; assisted hatching

In an effort to reduce the risk of fertilization failure, programs have broadened the use of ICSI to nonmale factor infertility. While it has been used in PGT to reduce the risk of DNA contamination, particularly in PGT-M (monogenic disorder) and PGT-SR (structural rearrangement) cases, ICSI has not been shown to improve outcomes when there is a normal sperm analysis.⁹ During IVF embryo development, assisted hatching involves the thinning and/or opening of the zona pellucida either by chemical, mechanical, or laser means around the embryo before transfer with the intention of facilitating implantation. The routine use of assisted hatching is not recommended based on the lack of increase in live birth rates and because it may increase multiple pregnancy and monozygotic twinning rates.¹⁰

9. Acupuncture

Four meta-analyses showed no evidence of the overall benefit of acupuncture for improving live birth rates regardless of whether acupuncture was performed around the time of oocyte retrieval or around the day of embryo transfer. Consequently, acupuncture cannot be recommended routinely to improve IVF outcomes.¹¹

10. Immunologic tests/treatments

Given the “foreign” genetic nature of a fetus, attempts to suppress the maternal immunologic response to sustain the pregnancy have been made for decades, especially for recurrent miscarriage and recurrent implantation failure with IVF. Testing has included natural killer (NK) cells, human leukocyte antigen (HLA) genotypes, and cytokines. While NK cells can be examined by endometrial biopsy, levels fluctuate based on the cycle phase, and no correlation between peripheral blood testing and uterine NK cell levels has been shown. Further, no consensus has been reached on reliable normal reference ranges in uterine NK cells.¹²

Several treatments have been proposed to somehow modulate the immune system during the implantation process thereby improving implantation and live birth, including lipid emulsion (intralipid) infusion, intravenous immunoglobulin, leukocyte immunization therapy, tacrolimus, anti–tumor necrosis factor agents, and granulocyte colony-stimulating factor. A recent systematic review and meta-analysis cited low-quality studies and did not recommend the use of any of these immune treatments.¹³ Further, immunomodulation has many known side effects, some of which are serious (including hepatosplenomegaly, thrombocytopenia, leukopenia, renal failure, thromboembolism, and anaphylactic reactions). Excluding women with autoimmune disease, taking glucocorticoids or other immune treatments to improve fertility has not been proven.¹³

Conclusion

To quote the New York Times opinion piece, “IVF remains an under-regulated arena, and entrepreneurial doctors and pharmaceutical and life science companies are eager to find new ways to cash in on a growing global market that is projected to be as large as $40 billion by 2024.” While this bold statement compels a huge “Ouch!”, it reminds us of our obligation to provide evidence-based medicine and to include emotional and financial harm to our oath of Primum non nocere.

In 2019, a New York Times opinion piece titled, “The Big IVF Add-On Racket – This is no way to treat patients desperate for a baby”¹ alleged exploitation of infertility patients based on a Fertility and Sterility article, “Do à la carte menus serve infertility patients? The ethics and regulation of in vitro fertility add-ons.”² The desperation of infertility patients combined with their financial burden, caused by inconsistent insurance coverage, has resulted in a perfect storm of frustration and overzealous recommendations for a successful outcome. Since the inception of in vitro fertilization (IVF) itself, infertility patients have been subjected to many unproven tests and procedures that enter the mainstream of care before unequivocal efficacy and safety have been shown.

Key takeaway

• Acute atrial fibrillation (AF) is an independent predictor of severity of neurological deficits from early acute ischemic stroke and a high-probability predictor of death within 30 days after such strokes.

Why this matters

• A comprehensive understanding of the relationship between acute AF and risk for acute ischemic stroke and prognosis will help improve management and treatment of patients with acute ischemic stroke.

Study design

• The retrospective study included patients with acute ischemic stroke within the prior 24 hours; 12-lead electrocardiogram in the emergency department; and hospitalization and treatment at the hospital stroke center.
• The cohort of 706 patients admitted to a single center in Shanghai, China, from December 2019 to December 2021, included 142 with episodes of acute AF and 564 without such episodes.
• Patients with acute ischemic stroke and acute AF – including AF of new onset, paroxysmal, persistent, or permanent with symptoms such as palpitations or dizziness attributed to rapid ventricular rates – were identified.
• Neurological deficits were assessed using the 7-day National Institutes of Health Stroke Scale/Score (NIHSS). Patients with a 7-day NIHSS score of at least 16 were considered to have moderate to severe stroke.
• Associations between acute AF onset and the severity of early neurological deficits were assessed and related to all-cause mortality within 30 days of the stroke.

Key results

• Patients with acute AF were older than those without acute AF (80.3 years vs. 71.0 years; P < .001).
• Baseline NIHSS scores averaged 16.09 for the stroke patients with acute AF and 8.65 for those without acute AF (P < .001).
• Significantly more patients with acute AF than without acute AF had a 7-day NIHSS score of at least 16 (45.1% vs. 14.4%; P < .001).
• More patients with than without acute AF underwent transcatheter thrombectomy (44.4% vs. 24.5%; P < .001) or received thrombolytic therapy (31.6% vs. 19.7%; P = .005).
• Patients aged 73 years or older showed baseline NIHSS score and acute AF as independent risk factors for early neurological deficits in stroke patients admitted to the emergency department.
• Mortality at 30 days was significantly higher in patients with acute AF than in those without acute AF (30.3% vs. 10.1%; P < .001).
• Baseline NIHSS had an adjusted odds ratio for 30-day mortality of 1.18 (95% confidence interval, 1.15-1.22; P < .001).  
• Other independent predictors included acute AF (1.87 [95% CI, 1.09-3.19; P = .022]) and age 73 or older (2.00 [95% CI, 1.18-3.37; P = .01]).

Limitations

• The study was retrospective and didn’t have access to some potentially relevant data, such as duration of AF.
• The single-center study with limited generalizability does not necessarily represent the broad population of stroke patients in China or elsewhere.

Disclosures

• This study was supported by the Cardiovascular Multidisciplinary Integrated Research Fund and Construction of Shanghai Municipal Health Commission.
• The authors report no relevant financial relationships.

The asthma medication tezepelumab, added to subcutaneous immunotherapy treatment (SCIT), may provide better, longer-lasting symptom relief than allergy shots alone for patients with allergic rhinitis caused by cat allergens, according to results of a phase 1/2 clinical trial.

“One year of allergen immunotherapy [AIT] combined with tezepelumab was significantly more effective than SCIT alone in reducing the nasal response to allergen challenge both at the end of treatment and one year after stopping treatment,” lead study author Jonathan Corren, MD, of the University of California, Los Angeles, and his colleagues wrote in The Journal of Allergy and Clinical Immunology.

“This persistent improvement in clinical response was paralleled by reductions in nasal transcripts for multiple immunologic pathways, including mast cell activation.”

The study was cited in a news release from the National Institutes of Health that said that the approach may work in a similar way with other allergens.

The Food and Drug Administration recently approved tezepelumab for the treatment of severe asthma in people aged 12 years and older. Tezelumab, a monoclonal antibody, works by blocking the cytokine thymic stromal lymphopoietin (TSLP).

“Cells that cover the surface of organs like the skin and intestines or that line the inside of the nose and lungs rapidly secrete TSLP in response to signals of potential danger,” according to the NIH news release. “In allergic disease, TSLP helps initiate an overreactive immune response to otherwise harmless substances like cat dander, provoking airway inflammation that leads to the symptoms of allergic rhinitis.”
 

Testing an enhanced strategy

The double-blind CATNIP trial was conducted by Dr. Corren and colleagues at nine sites in the United States. The trial included patients aged 18-65 years who’d had moderate to severe cat-induced allergic rhinitis for at least 2 years from 2015 to 2019.

The researchers excluded patients with recurrent acute or chronic sinusitis. They excluded patients who had undergone SCIT with cat allergen within the past 10 years or seasonal or perennial allergen sensitivity during nasal challenges. They also excluded persons with a history of persistent asthma.

In the parallel-design study, 121 participants were randomly allocated into four groups: 32 patients were treated with intravenous tezepelumab plus cat SCIT, 31 received the allergy shots alone, 30 received tezepelumab alone, and 28 received placebo alone for 52 weeks, followed by 52 weeks of observation.

Participants received SCIT (10,000 bioequivalent allergy units per milliliter) or matched placebo via subcutaneous injections weekly in increasing doses for around 12 weeks, followed by monthly maintenance injections (4,000 BAU or maximum tolerated dose) until week 48.

They received tezepelumab (700 mg IV) or matched placebo 1-3 days prior to the SCIT or placebo SCIT injections once every 4 weeks through week 24, then before or on the same day as the SCIT or placebo injections through week 48.
 

Measures of effectiveness

Participants were also given nasal allergy challenges – one spritz of a nasal spray containing cat allergen extract in each nostril at screening, baseline, and weeks 26, 52, 78, and 104. The researchers recorded participants’ total nasal symptom score (TNSS) and peak nasal inspiratory flow at 5, 15, 30, and 60 minutes after being sprayed and hourly for up to 6 hours post challenge. Blood and nasal cell samples were also collected.

The research team performed skin prick tests using serial dilutions of cat extract and an intradermal skin test (IDST) using the concentration of allergen that produced an early response of at least 15 mm at baseline. They measured early-phase responses for the both tests at 15 minutes and late-phase response to the IDST at 6 hours.

They measured serum levels of cat dander–specific IgE, IgG4, and total IgE using fluoroenzyme immunoassay. They measured serum interleukin-5 and IL-13 using high-sensitivity single-molecule digital immunoassay and performed nasal brushing using a 3-mm cytology brush 6 hours after a nasal allergy challenge. They performed whole-genome transcriptional profiling on the extracted RNA.
 

Combination therapy worked better and longer

The combined therapy worked better while being administered. Although the allergy shots alone stopped working after they were discontinued, the combination continued to benefit participants 1 year after that therapy ended.

At week 52, statistically significant reductions in TNSS induced by nasal allergy challenges occurred in patients receiving tezepelumab plus SCIT compared with patients receiving SCIT alone.

At week 104, 1 year after treatment ended, the primary endpoint TNSS was not significantly different in the tezepelumab-plus-SCIT group than in the SCIT-alone group, but TNSS peak 0–1 hour was significantly lower in the combination treatment group than in the SCIT-alone group.

In analysis of gene expression from nasal epithelial samples, participants who had been treated with the combination but not with either therapy by itself showed persistent modulation of the nasal immunologic environment, including diminished mast cell function. This was explained in large part by decreased transcription of the gene TPSAB1 (tryptase). Tryptase protein in nasal fluid was also decreased in the combination group, compared with the SCIT-alone group.

Adverse and serious adverse events, including infections and infestations as well as respiratory, thoracic, mediastinal, gastrointestinal, immune system, and nervous system disorders, did not differ significantly between treatment groups.
 

Four independent experts welcome the results

Patricia Lynne Lugar, MD, associate professor of medicine in the division of pulmonology, allergy, and critical care medicine at Duke University, Durham, N.C., found the results, especially the 1-year posttreatment response durability, surprising.

“AIT is a very effective treatment that often provides prolonged symptom improvement and is ‘curative’ in many cases,” she said in an interview. “If further studies show that tezepelumab offers long-term results, more patients might opt for combination therapy.

“A significant strength of the study is its evaluation of responses of the combination therapy on cellular output and gene expression,” Dr. Lugar added. “The mechanism by which AIT modulates the allergic response is largely understood. Tezepelumab may augment this modulation to alter the Th2 response upon exposure to the allergens.”
 

Will payors cover the prohibitively costly biologic?

Scott Frank, MD, associate professor in the department of family medicine and community health at Case Western Reserve University, Cleveland, called the study well designed and rigorous.

“The practicality of the approach may be limited by the need for intravenous administration of tezepelumab in addition to the traditional allergy shot,” he noted by email, “and the cost of this therapeutic approach is not addressed.”

Christopher Brooks, MD, clinical assistant professor of allergy and immunology in the department of otolaryngology at Ohio State University Wexner Medical Center, Columbus, also pointed out the drug’s cost.

“Tezepelumab is currently an expensive biologic, so it remains to be seen whether patients and payors will be willing to pay for this add-on medication when AIT by itself still remains very effective,” he said by email.

“AIT is most effective when given for 5 years, so it also remains to be seen whether the results and conclusions of this study would still hold true if done for the typical 5-year treatment period,” he added.

Stokes Peebles, MD, professor of medicine in the division of allergy, pulmonary, and critical care medicine at Vanderbilt University Medical Center, Nashville, Tenn., called the study “very well designed by a highly respected group of investigators using well-matched study populations.

“Tezepelumab has been shown to work in asthma, and there is no reason to think it would not work in allergic rhinitis,” he said in an interview.

“However, while the results of the combined therapy were statistically significant, their clinical significance was not clear. Patients do not care about statistical significance. They want to know whether a drug will be clinically significant,” he added.

Many people avoid cat allergy symptoms by avoiding cats and, in some cases, by avoiding people who live with cats, he said. Medical therapy, usually involving nasal corticosteroids and antihistamines, helps most people avoid cat allergy symptoms.

“Patients with bad allergies who have not done well with SCIT may consider adding tezepelumab, but it incurs a major cost. If medical therapy doesn’t work, allergy shots are available at roughly $3,000 per year. Adding tezepelumab costs around $40,000 more per year,” he explained. “Does the slight clinical benefit justify the greatly increased cost?”

The authors and uninvolved experts recommend further related research.

The research was supported by the National Institute of Allergy and Infectious Diseases. AstraZeneca and Amgen donated the drug used in the study. Dr. Corren reported financial relationships with AstraZeneca, and one coauthor reported relevant financial relationships with Amgen and other pharmaceutical companies. The remaining coauthors reported no relevant financial relationships.

The asthma medication tezepelumab, added to subcutaneous immunotherapy treatment (SCIT), may provide better, longer-lasting symptom relief than allergy shots alone for patients with allergic rhinitis caused by cat allergens, according to results of a phase 1/2 clinical trial.

“One year of allergen immunotherapy [AIT] combined with tezepelumab was significantly more effective than SCIT alone in reducing the nasal response to allergen challenge both at the end of treatment and one year after stopping treatment,” lead study author Jonathan Corren, MD, of the University of California, Los Angeles, and his colleagues wrote in The Journal of Allergy and Clinical Immunology.

“This persistent improvement in clinical response was paralleled by reductions in nasal transcripts for multiple immunologic pathways, including mast cell activation.”

The study was cited in a news release from the National Institutes of Health that said that the approach may work in a similar way with other allergens.

The Food and Drug Administration recently approved tezepelumab for the treatment of severe asthma in people aged 12 years and older. Tezelumab, a monoclonal antibody, works by blocking the cytokine thymic stromal lymphopoietin (TSLP).

“Cells that cover the surface of organs like the skin and intestines or that line the inside of the nose and lungs rapidly secrete TSLP in response to signals of potential danger,” according to the NIH news release. “In allergic disease, TSLP helps initiate an overreactive immune response to otherwise harmless substances like cat dander, provoking airway inflammation that leads to the symptoms of allergic rhinitis.”
 

Testing an enhanced strategy

The double-blind CATNIP trial was conducted by Dr. Corren and colleagues at nine sites in the United States. The trial included patients aged 18-65 years who’d had moderate to severe cat-induced allergic rhinitis for at least 2 years from 2015 to 2019.

The researchers excluded patients with recurrent acute or chronic sinusitis. They excluded patients who had undergone SCIT with cat allergen within the past 10 years or seasonal or perennial allergen sensitivity during nasal challenges. They also excluded persons with a history of persistent asthma.

In the parallel-design study, 121 participants were randomly allocated into four groups: 32 patients were treated with intravenous tezepelumab plus cat SCIT, 31 received the allergy shots alone, 30 received tezepelumab alone, and 28 received placebo alone for 52 weeks, followed by 52 weeks of observation.

Participants received SCIT (10,000 bioequivalent allergy units per milliliter) or matched placebo via subcutaneous injections weekly in increasing doses for around 12 weeks, followed by monthly maintenance injections (4,000 BAU or maximum tolerated dose) until week 48.

They received tezepelumab (700 mg IV) or matched placebo 1-3 days prior to the SCIT or placebo SCIT injections once every 4 weeks through week 24, then before or on the same day as the SCIT or placebo injections through week 48.

Texas-based researchers have developed a vaccine that blocks the euphoric effects of fentanyl, a potent synthetic opioid that is increasingly involved in opioid overdose deaths in the United States.

In studies in male and female mice, the vaccine generated significant and long-lasting levels of anti-fentanyl antibodies that were highly effective at reducing the antinociceptive, behavioral, and physiological effects of the drug.

The vaccine prevents fentanyl from entering the brain. “Thus, the individual will not feel the euphoric effects and can ‘get back on the wagon’ to sobriety,” lead investigator Colin Haile, MD, PhD, with University of Houston and founding member of the UH Drug Discovery Institute, said in a news release. The study was published online in the journal Pharmaceutics.

“The anti-fentanyl antibodies were specific to fentanyl and a fentanyl derivative and did not cross-react with other opioids, such as morphine. That means a vaccinated person would still be able to be treated for pain relief with other opioids,” said Dr. Haile.

The vaccine did not cause any adverse effects in the immunized mice. The research team plans to start manufacturing clinical-grade vaccine in the coming months with clinical trials in humans planned soon.

If proven safe and effective in clinical testing, the vaccine could have major implications for the nation’s opioid epidemic by becoming a relapse prevention agent for people trying to quit using opioids, the researchers note.

The United States in 2021 recorded more than 107,000 drug overdose deaths – a record high, according to federal health officials – and fentanyl was involved in most of these deaths. 

Senior author Therese Kosten, PhD, director of the UH Developmental, Cognitive & Behavioral Neuroscience program, calls the new fentanyl vaccine a potential “game changer.”

“Fentanyl use and overdose is a particular treatment challenge that is not adequately addressed with current medications because of its pharmacodynamics, and managing acute overdose with the short-acting naloxone [Narcan] is not appropriately effective as multiple doses of naloxone are often needed to reverse fentanyl’s fatal effects,” said Dr. Kosten.

Funding for the study was provided by the Department of Defense through the Alcohol and Substance Abuse Disorders Program managed by RTI International’s Pharmacotherapies for Alcohol and Substance Use Disorders Alliance, which has funded Dr. Haile’s lab for several years to develop the anti-fentanyl vaccine. The authors have no relevant conflicts of interest. A provisional patent has been submitted by the University of Houston on behalf of four of the investigators containing technology related to the fentanyl vaccine.

After recovery from acute infection with SARS-CoV-2, major stressful life events such as the death of a loved one or financial insecurity can have a significant impact on the development of long COVID symptoms, new research suggests.

Major life stressors in the year after hospital discharge for COVID-19 are “strongly predictive of a lot of the important outcomes that people may face after COVID,” lead investigator Jennifer A. Frontera, MD, a professor in the department of neurology at New York University Langone Health, said in an interview.

These outcomes include depression, brain fog, fatigue, trouble sleeping, and other long COVID symptoms.

The findings were published online in the Journal of the Neurological Sciences.
 

Major stressful events common

Dr. Frontera and the NYU Neurology COVID-19 study team evaluated 451 adults who survived a COVID hospital stay. Of these, 383 completed a 6-month follow-up, 242 completed a 12-month follow-up, and 174 completed follow-up at both time points. 

Within 1 year of discharge, 77 (17%) patients died and 51% suffered a major stressful life event.

In multivariable analyses, major life stressors – including financial insecurity, food insecurity, death of a close contact, and new disability – were strong independent predictors of disability, trouble with activities of daily living, depression, fatigue, sleep problems, and prolonged post-acute COVID symptoms. The adjusted odds ratios for these outcomes ranged from 2.5 to 20.8. 

The research also confirmed the contribution of traditional risk factors for long COVID symptoms, as shown in past studies. These include older age, poor pre-COVID functional status, and more severe initial COVID-19 infection.

Long-term sequelae of COVID are increasingly recognized as major public health issues. 

It has been estimated that roughly 16 million U.S. adults aged 18-65 years ave long COVID, with the often debilitating symptoms keeping up to 4 million out of work. 
 

Holistic approach

Dr. Frontera said it’s important to realize that “sleep, fatigue, anxiety, depression, even cognition are so interwoven with each other that anything that impacts any one of them could have repercussions on the other.”

She added that it “certainly makes sense that there is an interplay or even a bidirectional relationship between the stressors that people face and how well they can recover after COVID.”

Therapies that lessen the trauma of the most stress-inducing life events need to be a central part of treatment for long COVID, with more research needed to validate the best approaches, Dr. Frontera said.

She also noted that social services or case management resources may be able to help address at least some of the stressors that individuals are under – and it is important to refer them to these resources. Referral to mental health services is also important.

“I think it’s really important to take a holistic approach and try to deal with whatever the problem may be,” said Dr. Frontera.

“I’m a neurologist, but as part of my evaluation, I really need to address if there are life stressors or mental health issues that may be impacting this person’s function,” she added.

The study had no commercial funding. The investigators reported no relevant financial relationships.

In multivariable analyses, major life stressors – including financial insecurity, food insecurity, death of a close contact, and new disability – were strong independent predictors of disability, trouble with activities of daily living, depression, fatigue, sleep problems, and prolonged post-acute COVID symptoms. The adjusted odds ratios for these outcomes ranged from 2.5 to 20.8. 

The research also confirmed the contribution of traditional risk factors for long COVID symptoms, as shown in past studies. These include older age, poor pre-COVID functional status, and more severe initial COVID-19 infection.

Long-term sequelae of COVID are increasingly recognized as major public health issues. 

It has been estimated that roughly 16 million U.S. adults aged 18-65 years ave long COVID, with the often debilitating symptoms keeping up to 4 million out of work. 
 

Holistic approach

Dr. Frontera said it’s important to realize that “sleep, fatigue, anxiety, depression, even cognition are so interwoven with each other that anything that impacts any one of them could have repercussions on the other.”

She added that it “certainly makes sense that there is an interplay or even a bidirectional relationship between the stressors that people face and how well they can recover after COVID.”

Therapies that lessen the trauma of the most stress-inducing life events need to be a central part of treatment for long COVID, with more research needed to validate the best approaches, Dr. Frontera said.

She also noted that social services or case management resources may be able to help address at least some of the stressors that individuals are under – and it is important to refer them to these resources. Referral to mental health services is also important.

“I think it’s really important to take a holistic approach and try to deal with whatever the problem may be,” said Dr. Frontera.

“I’m a neurologist, but as part of my evaluation, I really need to address if there are life stressors or mental health issues that may be impacting this person’s function,” she added.

The study had no commercial funding. The investigators reported no relevant financial relationships.

After recovery from acute infection with SARS-CoV-2, major stressful life events such as the death of a loved one or financial insecurity can have a significant impact on the development of long COVID symptoms, new research suggests.

Major life stressors in the year after hospital discharge for COVID-19 are “strongly predictive of a lot of the important outcomes that people may face after COVID,” lead investigator Jennifer A. Frontera, MD, a professor in the department of neurology at New York University Langone Health, said in an interview.

These outcomes include depression, brain fog, fatigue, trouble sleeping, and other long COVID symptoms.

The findings were published online in the Journal of the Neurological Sciences.

On one of the first days of medical school, Adaira Landry, MD, applied her favorite dark shade of lipstick and headed to her orientation. She was eager to learn about program expectations and connect with fellow aspiring physicians. But when Dr. Landry got there, one of her brand-new peers turned to her and asked, “Why do you wear your lipstick like an angry Black woman?”

“Imagine hearing that,” Dr. Landry, now an emergency medical physician in Boston, says. “It was so hurtful.”

So, what is a “standard-issue doctor” expected to look like? Physicians manage their appearances in myriad ways: through clothes, accessories, hair style, makeup; through a social media presence or lack thereof; in the rhythms and nuances of their interactions with patients and colleagues. These things add up to a professional “persona” – the Latin word for “mask,” or the face on display for the world to see.

Professional personae exist across various industries, but some standards for professionalism in medicine reflect a particularly narrow view of what a physician can or should be. While the health care field itself is diversifying, its guidelines for professionalism appear slower to change, often excluding or frowning upon expressions of individual personality or identity.

“Medicine is run primarily by men. It’s an objective truth,” Dr. Landry says. “Currently and historically, the standard of professionalism, especially in the physical sense, was set by them. As we increase diversity and welcome people bringing their authentic self to work, the prior definitions of professionalism are obviously in need of change.”
 

Split social media personalities

In August 2020, the Journal of Vascular Surgery published a study on the “prevalence of unprofessional social media content among young vascular surgeons.” The content that was deemed “unprofessional” included opinions on political issues like abortion and gun control. Photos of physicians holding alcoholic drinks or wearing “inappropriate/offensive attire,” including underwear, “provocative Halloween costumes,” and “bikinis/swimwear” were also censured. Six men and one woman worked on the study, and three of the male researchers took on the task of seeking out the “unprofessional” photos on social media. The resulting paper was reviewed by an all-male editorial board.

The study sparked immediate backlash and prompted hundreds of health care professionals to post photos of themselves in bathing suits with the hashtag “#medbikini.” The journal then retracted the study and issued an apology on Twitter, recognizing “errors in the design of the study with regards to conscious and unconscious bias.”

The researchers’ original definition of professionalism suggests that physicians should manage their personae even outside of work hours. “I think medicine in general is a very conservative and hierarchical field of study and of work, to say the least,” says Sarah Fraser, MD, a family medicine physician in Nova Scotia, Canada. “There’s this view that we have to have completely separate personal and professional lives, like church and state.”

The #medbikini controversy inspired Dr. Fraser to write an op-ed for the British Medical Journal blog about the flaws of requiring physicians to keep their personal and professional selves separate. The piece referenced Robert Louis Stevenson’s 1886 Gothic novella “The Strange Case of Dr. Jekyll and Mr. Hyde,” in which the respected scientist Dr. Jekyll creates an alter ego so he can express his evil urges without experiencing guilt, punishment, or loss of livelihood. Dr. Fraser likened this story to the pressure physicians feel to shrink or split themselves to squeeze into a narrow definition of professionalism.

But Dr. Landry points out that some elements of expression seen as unprofessional cannot be entirely separated from a physician’s fundamental identity. “For Black women, our daily behaviors and forms of expression that are deemed ‘unprofessional’ are much more subtle than being able to wear a bikini on social media,” she says. “The way we wear our hair, the tone of our voice, the color of our lipstick, the way we wear scrub caps are parts of us that are called into question.”
 

Keeping up appearances

The stereotype of what a doctor should look like starts to shape physicians’ professional personae in medical school. When Jennifer Caputo-Seidler, MD, started medical school in 2008, the dress code requirements for male students were simple: pants, a button-down shirt, a tie. But then there were the rules for women: Hair should be tied back. Minimal makeup. No flashy jewelry. Nothing without sleeves. Neutral colors. High necklines. Low hemlines. “The message I got was that we need to dress like the men in order to be taken seriously and to be seen as professional,” says Dr. Caputo-Seidler, now an assistant professor of medicine at the University of South Florida, Tampa, “and so that’s what I did.”

A 2018 analysis of 78 “draw-a-scientist” studies found that children have overwhelmingly associated scientific fields with men for the last 50 years. Overall, children drew 73% of scientists as men. The drawings grew more gender diverse over time, but even as more women entered scientific fields, both boys and girls continued to draw significantly more male than female scientists.

Not everyone at Dr. Caputo-Seidler’s medical school adhered to the environment’s gendered expectations. One resident she worked with often wore voluminous hairstyles, lipstick, and high heels. Dr. Caputo-Seidler overheard her peers as they gossiped behind the resident’s back, ridiculing the way she looked.

“She was good at her job,” Dr. Caputo-Seidler says. “She knew her patients. She had things down. She was, by all measures, very competent. But when people saw her dressing outside the norm and being forward with her femininity, there was definitely a lot of chatter about it.”

While expectations for a conservative appearance may disproportionately affect women, and particularly women of color, they also affect men who deviate from the norm. “As an LGBTQ+ person working as a ‘professional,’ I have countless stories and moments where I had my professionalism questioned,” Blair Peters, MD, a plastic surgeon and assistant professor at Oregon Health & Science University, Portland, wrote on Twitter. “Why is it ‘unprofessional’ to have colored hair? Why is it ‘unprofessional’ to have a visible tattoo? Why is it ‘unprofessional’ to wear bright colors and patterns?”

Dr. Fraser remembers a fellow medical student who had full-sleeve tattoos on both of his arms. A preceptor made a comment about it to Dr. Fraser, and then instructed the student to cover up his tattoos. “I think that there are scenarios when having tattoos or having different-colored hair or expressing your individual personality could help you even better bond with your patients,” Dr. Fraser says, “especially if you’re, for example, working with youth.”
 

Unmasking health care

Beyond the facets of dress codes and social media posts, the issue of professional personae speaks to the deeper issue of inclusion in medicine. As the field grows increasingly diverse, health care institutions and those they serve may need to expand their definitions of professionalism to include more truthful expressions of who contemporary health care professionals are as people.

Dr. Fraser suggests that the benefits of physicians embracing self-expression – rather than assimilating to an outdated model of professionalism – extend beyond the individual.

“Whether it comes to what you choose to wear to the clinic on a day-to-day basis, or what you choose to share on a social media account, as long as it’s not harming others, then I think that it’s a positive thing to be able to be yourself and express yourself,” she says. “I feel like doctors are expected to have a different personality when we’re at the clinic, and usually it’s more conservative or objective or aloof. But I think that by being open about who we are, we’ll actually help build a trusting relationship with both patients and society.”
