EXPERT COMMENTARY

Maternal peripartum infection is 1 of the top 5 causes of maternal death, accounting for about 10% of cases of maternal mortality. Cesarean delivery (CD), of course, is the most important risk factor for puerperal infection. However, even vaginal delivery, particularly in low- to middle-resource countries, where deliveries often occur under less-than-optimal conditions, may be associated with a surprisingly high frequency of both maternal and neonatal infections. The beneficial effect of prophylactic antibiotics for CD is well established. An important remaining question is whether similar benefit can be achieved with prophylaxis for women planning to have a vaginal birth.

In 2017, Oluwalana and colleagues conducted a prospective, randomized, double-blind, placebo-controlled trial of a single 2-g oral dose of azithromycin in Gambian women undergoing labor.¹ During the 8 weeks after delivery, maternal infections were lower in the azithromycin group, 3.6% versus 9.2% (relative risk [RR], 0.40; 95% confidence interval [CI], 0.22–0.71; P=.002). Infections also were lower in the newborns, 18.1% versus 23.8% (RR, 0.76; 95% CI, 0.58–0.99; P=.052), delivered to mothers who received azithromycin. The greatest impact on neonatal infections was the reduced frequency of skin infections.

In 2021, Subramaniam and colleagues evaluated the effect of a single dose of oral azithromycin with, or without, amoxicillin on the prevalence of peripartum infection in laboring women in Cameroon.² Patients and their newborns were followed for 6 weeks after delivery. Unlike the previous investigation, the authors were unable to show a protective effect of prophylaxis on either maternal or neonatal infection.

Against this backdrop, Tita and colleagues conducted a remarkably large, well-designed, randomized, placebo-controlled study of azithromycin prophylaxis in women at 8 different sites in 7 low- or middle-income countries (the A-PLUS investigation).³

Details of the study

The investigators randomly assigned 29,278 patients at or beyond 28 weeks’ gestation to receive either a 2-g oral dose of azithromycin or placebo during labor. This particular drug was chosen because it is readily available, inexpensive, well tolerated, and has a broad range of activity against many important pelvic pathogens, including genital mycoplasmas. Some patients also received other antibiotics, for example, for group B streptococcal (GBS) prophylaxis or for CD prophylaxis if abdominal delivery was indicated.

The 2 primary outcomes were a composite of maternal sepsis or death and a composite of stillbirth or neonatal death or sepsis within 4 weeks of delivery. Secondary outcomes included individual components of the primary outcomes.

Results. The results of the investigation were compelling, and the data safety monitoring committee recommended stopping the trial early because of clear maternal benefit. The groups were well balanced with respect to important characteristics, such as incidence of CD, receipt of other prophylactic antibiotics, and median time between randomization and delivery.

The incidence of maternal sepsis or death was lower in the azithromycin group (1.6% vs 2.4%; RR, 0.67; 95% CI, 0.56–0.79; P<.001). The key effect was on the frequency of maternal sepsis because the incidence of maternal death was very low in both groups, 0.1%. With respect to secondary outcomes, prophylaxis was effective in reducing the frequency of endometritis (RR, 0.66; 95% CI, 0.55–0.79) and perineal and incisional infection (RR, 0.71; 95% CI, 0.56–0.85).

There was no difference in the frequency of neonatal sepsis or death. There also was no difference in the frequency of adverse drug effects in either group. Of note, more cases of neonatal pyloric stenosis were observed in the azithromycin group, but the overall incidence was lower than the expected background rate. This possible “signal” is important because this effect has been noted with increased frequency in neonates who received this antibiotic. ●

First trimester miscarriage, the presence of a nonviable intrauterine pregnancy before 13 weeks’ gestation, is a common complication occurring in approximately 15% of clinical pregnancies.^1,2 The goals for the holistic management of first-trimester miscarriage are to 1) reduce the risk of complications such as excessive bleeding and infection, 2) ensure that the patient is supported during a time of great distress, and 3) optimally counsel the patient about treatment options and elicit the patient’s preferences for care.³ To resolve a miscarriage, the intrauterine pregnancy tissue must be expelled, restoring normal reproductive function.

The options for the management of a nonviable intrauterine pregnancy include expectant management, medication treatment with mifepristone plus misoprostol or misoprostol-alone, or uterine aspiration. In the absence of uterine hemorrhage, infection, or another severe complication of miscarriage, the patient’s preferences should guide the choice of treatment. Many patients with miscarriage prioritize avoiding medical interventions and may prefer expectant management. A patient who prefers rapid and reliable completion of the pregnancy loss process may prefer uterine aspiration. If the patient prefers to avoid uterine aspiration but desires control over the time and location of the expulsion process, medication treatment may be optimal. Many other factors influence a patient’s choice of miscarriage treatment, including balancing work and childcare issues and the ease of scheduling a uterine aspiration. In counseling patients about the options for miscarriage treatment it is helpful to know the success rate of each treatment option.⁴ This editorial reviews miscarriage treatment outcomes as summarized in a recent Cochrane network meta-analysis.⁵

Uterine aspiration versus mifepristone-misoprostol

In 2 clinical trials that included 899 patients with miscarriage, successful treatment with uterine aspira-tion versus mifepristone-misoprostolwas reported in 95% and 66% of cases, respectively.^6,7

In the largest clinical trial comparing uterine aspiration to mifepristone-misoprostol, 801 patients with first-trimester miscarriage were randomly assigned to uterine aspiration or mifepristone-misoprostol.⁶ Uterine aspiration and mifepristone-misoprostol were associated with successful miscarriage treatment in 95% and 64% of cases, respectively. In the uterine aspiration group, a second uterine aspiration occurred in 5% of patients. Two patients in the uterine aspiration group needed a third uterine aspiration to resolve the miscarriage. In the mifepristone-misoprostol group, 36% of patients had a uterine aspiration. It should be noted that the trial protocol guided patients having a medication abortion to uterine aspiration if expulsion of miscarriage tissue had not occurred within 8 hours of receiving misoprostol. If the trial protocol permitted 1 to 4 weeks of monitoring after mifepristone-misoprostol treatment, the success rate with medication treatment would be greater. Six to 8 weeks following miscarriage treatment, patient-reported anxiety and depression symptoms were similar in both groups.⁶

Uterine aspiration versus misoprostol

Among 3 clinical trials that limited enrollment to patients with missed miscarriage, involving 308 patients, the success rates for uterine aspiration and misoprostol treatment was 95% and 62%, respectively.⁵

In a study sponsored by the National Institutes of Health, 652 patients with missed miscarriage or incomplete miscarriage were randomly assigned in a 1:3 ratioto uterine aspiration or misoprostol treatment (800 µg vaginally). After 8 days of follow-up, successful treatment rates among the patients treated with uterine evacuation or misoprostol was 97% and 84%, respectively.⁸ Of note, with misoprostol treatment the success rate increased from day 3 to day 8 of follow-up—from 71% to 84%.⁸

Continue to: Mifepristone-misoprostol versus misoprostol...

The combined results of 7 clinical trials of medication management of missed miscarriage that included 1,812 patients showed that successful treatment with mifepristone-misoprostol or misoprostol alone occurred in 80% and 70% of cases, respectively.⁵

Schreiber and colleagues⁹ reported a study of 300 patients with an anembryonic gestation or embryonic demise that were between 5 and 12 completed weeks of gestation and randomly assigned to treatment with mifepristone (200 mg) plus vaginal misoprostol (800 µg) administered 24 to 48 hours after mifepristone or vaginal misoprostol (800 µg) alone. Ultrasonography was performed 1 to 4 days after misoprostol administration. Successful treatment was defined as expulsion of the gestational sac plus no additional surgical or medical intervention within 30 days after treatment. In this study, the dual-medication regimen of mifepristone-misoprostol was more successful than misoprostol alone in resolving the miscarriage, 84% and 67%, respectively (relative risk [RR], 1.25; 95% CI, 1.09–1.43). Surgical evacuation of the uterus occurred less often with mifepristone-misoprostol treatment (9%) than with misoprostol monotherapy (24%) (RR, 0.37; 95% CI, 0.21 ̶ 0.68). Pelvic infection occurred in 2 patients (1.3%) in each group. Uterine bleeding managed with blood transfusion occurred in 3 patients who received mifepristone-misoprostol and 1 patient who received misoprostol alone. In this study, clinical factors, including active bleeding, parity, and gestational age did not influence treatment success with the mifepristone-misoprostol regimen.¹⁰ The mifepristone-misoprostol regimen was reported to be more cost-effective than misoprostol alone.¹¹Chu and colleagues¹² reporteda study of medication treatmentof missed miscarriage that included more than 700 patients randomly assigned to treatment with mifepristone-misoprostol or placebo-misoprostol. Missed miscarriage was diagnosed by an ultrasound demonstrating a gestational sac and a nonviable pregnancy. The doses of mifepristone and misoprostol were 200 mg and 800 µg, respectively. In this study, the misoprostol was administered 48 hours following mifepristone or placebo using a vaginal, oral, or buccal route; 90% of patients used the vaginal route. Treatment was considered successful if the patient passed the gestational sac as determined by an ultrasound performed 7 days after entry into the study. If the gestational sac was passed, the patients were asked to do a urine pregnancy test 3 weeks after entering the study to conclude their care episode. If patients did not pass the gestational sac, they were offered a second dose of misoprostol or surgical evacuation. At 7 days of follow-up, the success rates in the mifepristone-misoprostol and misoprostol-alone groups were 83% and 76%, respectively. Surgical intervention was performed in 25% of patients treated with placebo-misoprostol and 17% of patients treated with mifepristone-misoprostol (RR, 0.73; 95% CI, 0.53 ̶ 0.95; P=.021).¹² A cost-effectiveness analysis of the trial results reported that the combination of mifepristone-misoprostol was less costly than misoprostolalone for the management of missed miscarriages.¹³

Expectant management versus uterine aspiration

The combined results of 7 clinical trials that included a total of 1,693 patients showed that successful treatment of miscarriage with expectant management or uterine aspiration occurred in 68% and 93% of cases, respectively.⁵ In one study, 700 patients with miscarriage were randomly assigned to expectant management or uterine aspiration. Treatment was successful for 56% and 95% of patients in the expectant management and uterine aspiration groups, respectively.⁶

The Cochrane network meta-analysis concluded that cervical preparation followed by uterine aspiration may be more effective than expectant management, with a reported risk ratio (RR) of 2.12 (95% CI, 1.41–3.20) with low-certainty evidence.⁵ In addition, uterine aspiration compared with expectant management may reduce the risk of serious complications (RR, 0.55; 95% CI, 0.23–1.32), with a wide range of treatment effects in reported trials and low-certainty evidence.⁵

In the treatment of miscarriage, the efficacy of expectant management may vary by the type of miscarriage. In one study, following the identification of a miscarriage, the percent of patients who have completed the expulsion of pregnancy tissue by 14 days was reported to be 84% for incomplete miscarriage, 59% for pregnancy loss with no expulsion of tissue, and 52% with ultrasound detection of a nonviable pregnancy with a gestational sac.¹⁴

Expectant management versus mifepristone-misoprostol

Aggregated data from 3 clinical trials that included a total of 910 patients showed that successful treatment with expectant management or mifepristone-misoprostol was reported in 48% and 68% of cases, respectively.⁵ The Cochrane network meta-analysis concluded that mifepristone-misoprostol may be more effective than expectant management, with a risk ratio of 1.42 (95% CI, 1.22–1.66) with low-certainty evidence. In addition, mifepristone-misoprostol compared with expectant management may reduce the risk for serious complications (RR, 0.76; 95% CI, 0.31–1.84) with wide range of treatment effects and low-certainty evidence.⁵

Continue to: Expectant management versus misoprostol...

The combined results of 10 clinical trials that included a total of 838 patients with miscarriage, showed that successful treatment with expectant management or misoprostol-alone occurred in 44% and 75% of cases, respectively.⁵ Among 3 studies limiting enrollment to patients with missed miscarriage, successful treatment with expectant management or misoprostol-alone occurred in 32% and 70%, respectively.⁵

The Cochrane analysis concluded that misoprostol-alone may be more effective than expectant management, with a reported risk ratio of 1.30 (95% CI, 1.16–1.46) with low-certainty evidence. In addition, misoprostol-alone compared with expectant management may reduce the risk of serious complications (RR, 0.50; 95% CI, 0.22–1.15) with a wide range of treatment effects and low-certainty evidence.⁵

Patient experience of miscarriage care

Pregnancy loss is often a distressing experience, which is associated with grief, anxiety, depression, and guilt, lasting up to 2 years for some patients.^15,16 Patient dissatisfaction with miscarriage care often focuses on 4 issues: a perceived lack of emotional support, failure to elicit patient preferences for treatment, insufficient provision of information, and inconsistent posttreatment follow-up.^17-19 When caring for patients with miscarriage, key goals are to communicate medical information with empathy and to provide emotional support. In the setting of a miscarriage, it is easy for patients to perceive that the clinician is insensitive and cold.¹⁵ Expressions of sympathy, compassion, and condolence help build an emotional connection and improve trust with the patient. Communications that may be helpful include: “I am sorry for your loss,” “I wish the outcome could be different,” “Our clinical team wants to provide you the best care possible,” and “May I ask how you are feeling?” Many patients report that they would like to have been offered mental health services as part of their miscarriage care.¹⁵

The Cochrane network meta-analysis of miscarriage concluded that uterine aspiration, misoprostol-mifepristone, and misoprostol-alone were likely more effective in resolving a miscarriage than expectant management.⁵ The strength of the conclusion was limited because of significant heterogeneity among studies, including different inclusion criteria, definition of success, and length of follow-up. Clinical trials with follow-up intervals more than 7 days generally reported greater success rates with expectant¹⁴ and medication management⁸ than studies with short follow-up intervals. Generally, expectant or medication management treatment is more likely to be successful in cases of incomplete abortion than in cases of missed miscarriage.⁵

In a rank analysis of treatment efficacy, uterine aspiration was top-ranked, followed by medication management. Expectant management had the greatest probability of being associated with unplanned uterine aspiration. Based on my analysis of available miscarriage studies, I estimate that the treatment success rates are approximately:

• uterine aspiration (93% to 99%)
• misoprostol-mifepristone (66% to 84%)
• misoprostol-alone (62% to 76%)
• expectant management (32% to 68%).

Although there may be significant differences in efficacy among the treatment options, offering patients all available approaches to treatment, providing information about the relative success of each approach, and eliciting the patient preference for care ensures an optimal patient experience during a major life event. ●

In one study, following the identification of a miscarriage, the percent of patients who have completed the expulsion of pregnancy tissue by 14 days was reported to be 84% for incomplete miscarriage, 59% for pregnancy loss with no expulsion of tissue, and 52% with ultrasound detection of a nonviable pregnancy with a gestational sac.¹⁴

Expectant management versus mifepristone-misoprostol

Aggregated data from 3 clinical trials that included a total of 910 patients showed that successful treatment with expectant management or mifepristone-misoprostol was reported in 48% and 68% of cases, respectively.⁵ The Cochrane network meta-analysis concluded that mifepristone-misoprostol may be more effective than expectant management, with a risk ratio of 1.42 (95% CI, 1.22–1.66) with low-certainty evidence. In addition, mifepristone-misoprostol compared with expectant management may reduce the risk for serious complications (RR, 0.76; 95% CI, 0.31–1.84) with wide range of treatment effects and low-certainty evidence.⁵

The combined results of 10 clinical trials that included a total of 838 patients with miscarriage, showed that successful treatment with expectant management or misoprostol-alone occurred in 44% and 75% of cases, respectively.⁵ Among 3 studies limiting enrollment to patients with missed miscarriage, successful treatment with expectant management or misoprostol-alone occurred in 32% and 70%, respectively.⁵

The Cochrane analysis concluded that misoprostol-alone may be more effective than expectant management, with a reported risk ratio of 1.30 (95% CI, 1.16–1.46) with low-certainty evidence. In addition, misoprostol-alone compared with expectant management may reduce the risk of serious complications (RR, 0.50; 95% CI, 0.22–1.15) with a wide range of treatment effects and low-certainty evidence.⁵

Patient experience of miscarriage care

Pregnancy loss is often a distressing experience, which is associated with grief, anxiety, depression, and guilt, lasting up to 2 years for some patients.^15,16 Patient dissatisfaction with miscarriage care often focuses on 4 issues: a perceived lack of emotional support, failure to elicit patient preferences for treatment, insufficient provision of information, and inconsistent posttreatment follow-up.^17-19 When caring for patients with miscarriage, key goals are to communicate medical information with empathy and to provide emotional support. In the setting of a miscarriage, it is easy for patients to perceive that the clinician is insensitive and cold.¹⁵ Expressions of sympathy, compassion, and condolence help build an emotional connection and improve trust with the patient. Communications that may be helpful include: “I am sorry for your loss,” “I wish the outcome could be different,” “Our clinical team wants to provide you the best care possible,” and “May I ask how you are feeling?” Many patients report that they would like to have been offered mental health services as part of their miscarriage care.¹⁵

The Cochrane network meta-analysis of miscarriage concluded that uterine aspiration, misoprostol-mifepristone, and misoprostol-alone were likely more effective in resolving a miscarriage than expectant management.⁵ The strength of the conclusion was limited because of significant heterogeneity among studies, including different inclusion criteria, definition of success, and length of follow-up. Clinical trials with follow-up intervals more than 7 days generally reported greater success rates with expectant¹⁴ and medication management⁸ than studies with short follow-up intervals. Generally, expectant or medication management treatment is more likely to be successful in cases of incomplete abortion than in cases of missed miscarriage.⁵

In a rank analysis of treatment efficacy, uterine aspiration was top-ranked, followed by medication management. Expectant management had the greatest probability of being associated with unplanned uterine aspiration. Based on my analysis of available miscarriage studies, I estimate that the treatment success rates are approximately:

• uterine aspiration (93% to 99%)
• misoprostol-mifepristone (66% to 84%)
• misoprostol-alone (62% to 76%)
• expectant management (32% to 68%).

Although there may be significant differences in efficacy among the treatment options, offering patients all available approaches to treatment, providing information about the relative success of each approach, and eliciting the patient preference for care ensures an optimal patient experience during a major life event. ●
 

First trimester miscarriage, the presence of a nonviable intrauterine pregnancy before 13 weeks’ gestation, is a common complication occurring in approximately 15% of clinical pregnancies.^1,2 The goals for the holistic management of first-trimester miscarriage are to 1) reduce the risk of complications such as excessive bleeding and infection, 2) ensure that the patient is supported during a time of great distress, and 3) optimally counsel the patient about treatment options and elicit the patient’s preferences for care.³ To resolve a miscarriage, the intrauterine pregnancy tissue must be expelled, restoring normal reproductive function.

The options for the management of a nonviable intrauterine pregnancy include expectant management, medication treatment with mifepristone plus misoprostol or misoprostol-alone, or uterine aspiration. In the absence of uterine hemorrhage, infection, or another severe complication of miscarriage, the patient’s preferences should guide the choice of treatment. Many patients with miscarriage prioritize avoiding medical interventions and may prefer expectant management. A patient who prefers rapid and reliable completion of the pregnancy loss process may prefer uterine aspiration. If the patient prefers to avoid uterine aspiration but desires control over the time and location of the expulsion process, medication treatment may be optimal. Many other factors influence a patient’s choice of miscarriage treatment, including balancing work and childcare issues and the ease of scheduling a uterine aspiration. In counseling patients about the options for miscarriage treatment it is helpful to know the success rate of each treatment option.⁴ This editorial reviews miscarriage treatment outcomes as summarized in a recent Cochrane network meta-analysis.⁵

Uterine aspiration versus mifepristone-misoprostol

In 2 clinical trials that included 899 patients with miscarriage, successful treatment with uterine aspira-tion versus mifepristone-misoprostolwas reported in 95% and 66% of cases, respectively.^6,7

In the largest clinical trial comparing uterine aspiration to mifepristone-misoprostol, 801 patients with first-trimester miscarriage were randomly assigned to uterine aspiration or mifepristone-misoprostol.⁶ Uterine aspiration and mifepristone-misoprostol were associated with successful miscarriage treatment in 95% and 64% of cases, respectively. In the uterine aspiration group, a second uterine aspiration occurred in 5% of patients. Two patients in the uterine aspiration group needed a third uterine aspiration to resolve the miscarriage. In the mifepristone-misoprostol group, 36% of patients had a uterine aspiration. It should be noted that the trial protocol guided patients having a medication abortion to uterine aspiration if expulsion of miscarriage tissue had not occurred within 8 hours of receiving misoprostol. If the trial protocol permitted 1 to 4 weeks of monitoring after mifepristone-misoprostol treatment, the success rate with medication treatment would be greater. Six to 8 weeks following miscarriage treatment, patient-reported anxiety and depression symptoms were similar in both groups.⁶

Uterine aspiration versus misoprostol

Among 3 clinical trials that limited enrollment to patients with missed miscarriage, involving 308 patients, the success rates for uterine aspiration and misoprostol treatment was 95% and 62%, respectively.⁵

In a study sponsored by the National Institutes of Health, 652 patients with missed miscarriage or incomplete miscarriage were randomly assigned in a 1:3 ratioto uterine aspiration or misoprostol treatment (800 µg vaginally). After 8 days of follow-up, successful treatment rates among the patients treated with uterine evacuation or misoprostol was 97% and 84%, respectively.⁸ Of note, with misoprostol treatment the success rate increased from day 3 to day 8 of follow-up—from 71% to 84%.⁸

Continue to: Mifepristone-misoprostol versus misoprostol...

The combined results of 7 clinical trials of medication management of missed miscarriage that included 1,812 patients showed that successful treatment with mifepristone-misoprostol or misoprostol alone occurred in 80% and 70% of cases, respectively.⁵

Schreiber and colleagues⁹ reported a study of 300 patients with an anembryonic gestation or embryonic demise that were between 5 and 12 completed weeks of gestation and randomly assigned to treatment with mifepristone (200 mg) plus vaginal misoprostol (800 µg) administered 24 to 48 hours after mifepristone or vaginal misoprostol (800 µg) alone. Ultrasonography was performed 1 to 4 days after misoprostol administration. Successful treatment was defined as expulsion of the gestational sac plus no additional surgical or medical intervention within 30 days after treatment. In this study, the dual-medication regimen of mifepristone-misoprostol was more successful than misoprostol alone in resolving the miscarriage, 84% and 67%, respectively (relative risk [RR], 1.25; 95% CI, 1.09–1.43). Surgical evacuation of the uterus occurred less often with mifepristone-misoprostol treatment (9%) than with misoprostol monotherapy (24%) (RR, 0.37; 95% CI, 0.21 ̶ 0.68). Pelvic infection occurred in 2 patients (1.3%) in each group. Uterine bleeding managed with blood transfusion occurred in 3 patients who received mifepristone-misoprostol and 1 patient who received misoprostol alone. In this study, clinical factors, including active bleeding, parity, and gestational age did not influence treatment success with the mifepristone-misoprostol regimen.¹⁰ The mifepristone-misoprostol regimen was reported to be more cost-effective than misoprostol alone.¹¹Chu and colleagues¹² reporteda study of medication treatmentof missed miscarriage that included more than 700 patients randomly assigned to treatment with mifepristone-misoprostol or placebo-misoprostol. Missed miscarriage was diagnosed by an ultrasound demonstrating a gestational sac and a nonviable pregnancy. The doses of mifepristone and misoprostol were 200 mg and 800 µg, respectively. In this study, the misoprostol was administered 48 hours following mifepristone or placebo using a vaginal, oral, or buccal route; 90% of patients used the vaginal route. Treatment was considered successful if the patient passed the gestational sac as determined by an ultrasound performed 7 days after entry into the study. If the gestational sac was passed, the patients were asked to do a urine pregnancy test 3 weeks after entering the study to conclude their care episode. If patients did not pass the gestational sac, they were offered a second dose of misoprostol or surgical evacuation. At 7 days of follow-up, the success rates in the mifepristone-misoprostol and misoprostol-alone groups were 83% and 76%, respectively. Surgical intervention was performed in 25% of patients treated with placebo-misoprostol and 17% of patients treated with mifepristone-misoprostol (RR, 0.73; 95% CI, 0.53 ̶ 0.95; P=.021).¹² A cost-effectiveness analysis of the trial results reported that the combination of mifepristone-misoprostol was less costly than misoprostolalone for the management of missed miscarriages.¹³

Expectant management versus uterine aspiration

The combined results of 7 clinical trials that included a total of 1,693 patients showed that successful treatment of miscarriage with expectant management or uterine aspiration occurred in 68% and 93% of cases, respectively.⁵ In one study, 700 patients with miscarriage were randomly assigned to expectant management or uterine aspiration. Treatment was successful for 56% and 95% of patients in the expectant management and uterine aspiration groups, respectively.⁶

PHOENIX – Rapid, effective, and well-tolerated treatment of small cutaneous neurofibromas (cNF) without surgery or scarring is possible, with some tumors completely clearing after only one treatment, according to preliminary results of an ongoing prospective trial that compared several treatment modalities.

“Neurofibromatosis type 1 is the most common single-gene disease of mankind, but there is so much we have yet to learn about it,” study author Patricia Richey, MD, who practices Mohs surgery and cosmetic dermatology in Washington, D.C., said in an interview in advance of the annual conference of the American Society for Laser Medicine and Surgery, where she presented the results during an abstract session. Dr. Richey also conducts research for the Wellman Center for Photomedicine and the Dermatology Laser and Cosmetic Center at Massachusetts General Hospital, Boston, and is working with R. Rox Anderson, MD, director of the Wellman Center, on this project. In his words, she said, “the lack of better treatments for cNF is a ‘problem worth solving.’ ”

Four treatments vs. controls

For the study, Dr. Richey and colleagues enrolled 19 adults with a total of 307 cNFs measuring 2-4 mm in size to receive one of four treatments: electrocautery with an insulated radiofrequency needle; 755-nm alexandrite laser with negative pressure (8-mm spot size, 100 J/cm² fluence, 3-ms pulse duration); 980-nm diode laser (delivered via 8-mm sapphire skin-contact window), and intratumoral injection of 10 mg/mL deoxycholic acid at a volume approximately equal to that of the tumor. The average age of the participants was 49 years and 15 were female.

The investigators applied 5% lidocaine/prilocaine for 40 minutes to treatment sites before randomizing the tumors to treatment or to the control arm (no treatment). They compared safety, tolerability (including pain scores), and efficacy of each modality as measured by the change in cNF volume/height via three-dimensional imaging and clinical improvement via physician assessment at 6 months. All 19 participants have completed the 6-month assessment.

All modalities reduced or eliminated some of the cNFs by 6 months after treatment, with statistically significant reductions in height and volume across all four treatments. A wide variation of responses was observed. Specifically, the mean tumor volume changes for each modality, compared with controls, were –33.4% versus –5.1% among those treated with the 755-nm alexandrite laser; –24.9% versus –9.2% among those treated with the 980-nm diode laser, –23.3% versus –0.8% among those treated with insulated-needle radiofrequency coagulation, and –29.4% versus –3.7% among those treated with deoxycholic acid.

The variation in responses “may be due to histologic diversity of cNF or may indicate a need for more fine-tuned dosimetry, or a combination,” Dr. Richey said. “Our future trials will address this. We will also be treating all skin types in our upcoming trials.”

No adverse events categorized as higher than grade 2 occurred in any of the treatment groups, and no signs of regrowth or growth stimulation have been observed to date.

Tolerability of treatments

As for general tolerability, the 980-nm laser treatment caused moderate to severe pain; the alexandrite laser caused mild pain; insulated-needle radiofrequency coagulation caused mild pain, though more than deoxycholic acid injections or alexandrite laser, and pain associated with the deoxycholic acid injections was minimal.

When residual neurofibroma tumor was present histologically, its appearance was similar to that of untreated tumors in controls. There was no evidence of atypia, mitosis, or tumor inflammation, and mild fibrosis was present at the sites of prior tumor.

“It was surprising that all four modalities did work to some extent,” Dr. Richey said, noting that the lack of ulceration with deoxycholic acid injection “was pleasantly surprising.” Treatment with the 980-nm diode laser “was a bit more painful than we anticipated.”

The positive results of this trial has raised “more questions for us to answer. We have three additional trials in the works to fine tune these treatments and optimize dose/delivery, with the end goal of treating younger people.”

Dr. Richey said that she was “amazed” by how motivated the enrollees were to participate in the trial, noting that many patients with cNF undergo general anesthesia to have dozens of tumors surgically removed at once. “They pay $10,000-$20,000 on average out of pocket, as this surgery is considered cosmetic,” she said.

“This very important study could lead to effective, relatively noninvasive, therapy for small neurofibromas,” said Jeffrey S. Dover, MD, codirector of SkinCare Physicians in Chestnut Hill, Mass., who was not involved with the study and was asked to comment on the results.

“Remarkably, all four treatments worked to varying degrees, but of all the treatments, the selective alexandrite laser appeared to achieve the best results. Further study will be needed to see just how effective these treatments are, and to determine the best and safest treatment parameters. Given how common this autosomal dominant disease is, and how disfiguring neurofibromas become as they enlarge, a well-tolerated noninvasive nonsurgical treatment with limited side effects is highly sought after.”

The study, which was named the best clinical abstract at the meeting, was supported by the Neurofibromatosis Therapeutic Acceleration Program. Dr. Anderson is supported in part as the Lancer Endowed Chair in Dermatology at MGH. Dr. Dover reported having no relevant disclosures.

This article is part of a series from Medscape on vaping.

Every day, Sonia Sharma, PA, meets people like Natalie H., who is trying to quit vaping.

Natalie, a member of the nicotine addiction support group at the University of California San Francisco’s Fontana Tobacco Treatment Center, switched from traditional cigarettes to vaping but found the electronic version just as addictive and eventually decided to quit using nicotine completely.

“I went from being an occasional cigarette smoker, a few a month, to a daily vaper,” said Natalie, who preferred not to give her last name to protect her privacy. “Vaping made my nicotine addiction worse, not better.”

“We have people tell us they vape before their feet hit the ground in the morning,” said Ms. Sharma, who coleads Natalie’s support group at UCSF. Ms. Sharma has met individuals who had smoked four to five cigarettes a day, switched to e-cigarettes to quit smoking, then vaped the equivalent of a pack a day. Others had switched to vapes to quit but ended up both vaping and smoking again. And others picked up vaping without ever smoking. They want to quit, she said, but are not sure how.

Researchers from the National Institutes of Health in 2020 reported that 5.6 million  adults in the United States vaped. A little over 57% of people said they started using e-cigarettes to quit smoking traditional cigarettes. Another study in 2021 based on survey data found that about 60% of e-cigarette users wanted to quit their vaping habit. 

Vaping has been marketed as a way to help people kick their smoking habit. Research is inconclusive on this claim. But unlike cessation tools like nicotine gums or lozenges, using vapes for cessation is uncharted territory. Vapers lack guidance for how to use the devices to quit, and they have even less direction on what to do if they develop an addiction to the vapes themselves.
 

A new addiction?

Monica Hanna, MPH, assistant director of the Nicotine and Tobacco Recovery Program at RWJBarnabas Health’s Institute for Prevention and Recovery in New Jersey, said she has witnessed a higher level of nicotine addiction in the vapers with whom she has worked.

“When someone takes a hit from a vaping device, it doesn’t generate the burn it would from traditional tobacco,” Ms. Hanna said. “This causes people to take a deeper pull, and when they take a deeper pull, they establish a higher level of nicotine dependence over time.” 

A 2019 study of nearly 900 people published in the New England Journal of Medicine found that smokers who used vapes for cessation were twice as likely to have quit smoking cigarettes as those who used other nicotine replacement therapy. However, 80% of people who switched to vaping were using e-cigarettes a year after they tried to quit smoking.

Given that potential for addiction, Nancy Rigotti, MD, director of Massachusetts General Hospital’s Tobacco Research and Treatment Center in Boston, said patients must use vapes “properly” for cessation. That means giving up smoking completely and quitting vapes as soon as patients are sure they will not go back to smoking tobacco.

“We are going to need to help these people to stop vaping,” said Dr. Rigotti, who is working with Achieve Life Sciences, a pharmaceutical company developing a prescription drug to treat nicotine addiction from vapes and cigarettes.

And many nicotine users who have tried vaping to quit smoking end up becoming dual users.

“It’s important to stress that health benefits [of switching to vaping] only occur if the switch to vapes is complete and permanent. So far, that appears difficult to do for most people who smoke, and in my anecdotal experience it has not worked,” said J. Taylor Hays, MD, the former medical director of Mayo Clinic’s Nicotine Dependence Center in Rochester, Minn.

Besides challenges in communicating the current evidence, no established method exists to help vapers quit, according to Nigar Nargis, PhD, senior scientific director of tobacco control research at the American Cancer Society. 

“There are some experimental methods like using social interventions, counseling, and some educational campaigns,” Dr. Nargis said. “[Little] progress has been done in terms of clinical interventions.”

Unlike cessation products such as gum or a nicotine patch, which have clear recommendations for duration of use, similar guidelines don’t exist for vapes, in part because the U.S. Food and Drug Administration hasn’t yet granted approval of vapes as cessation products.

Alex Clark, the CEO of Consumer Advocates for Smoke-free Alternatives Association, a nonprofit group that supports vaping, said people could vape for longer and still benefit from making the switch from traditional cigarettes.

“The most important thing is that people start replacing cigarettes with a smoke-free product and continue until they’ve completely switched,” said Mr. Clark, whose group accepts donations from the e-cigarette industry. “Following switching, people are encouraged to continue with the product for as long as they feel necessary.”

But 2013 guidelines from the FDA advised makers of nicotine-replacement therapies – including gums, patches, and lozenges – to include labeling that advises users to complete treatment. According to the agency, if a person feels like they “need to use [the NRT product] for a longer period to keep from smoking, talk to your health care provider.”

Dr. Hays, who is now an emeritus professor at the Mayo Clinic, said he would not recommend patients try vaping as a cessation device given the availability of more proven techniques such as patches and gums. If a patient insists, vaping could be considered under the medical guidance of a cessation professional. He also advised people purchase products only from large tobacco companies that are likely to have “reasonable quality control.” Hundreds of vaping devices are on the market, and they are not all equivalent, he said.

But when an e-cigarette user wants to quit vaping, guidance might boil down to using traditional tobacco cessation methods like gums and lozenges because few tools exist to help people with a vaping-specific addiction.

The long-term health outcomes of vaping are also unclear, and decades will pass before scientists are able to make conclusions, according to Thomas Eissenberg, PhD, codirector of Virginia Commonwealth University’s Center for the Study of Tobacco Products in Richmond.

“I don’t think anyone knows what the long-term effects of heated propylene glycol and vegetable glycerin and flavors intended as food ingredients are, especially when these compounds are inhaled hundreds of times a day, week after week, year after year,” Dr. Eissenberg said.

Dr. Rigotti reported that she receives no funding from the tobacco or e-cigarette industry. She is working with Achieve Life Sciences to develop a tool for vaping cessation. Dr. Eissenberg, Ms. Hanna, Dr. Hays, Dr. Nargis, and Ms. Sharma reported no funding from the tobacco or e-cigarette industry.

Women harboring BRCA1/2 gene mutations are at high risk for breast cancer, and thus it’s recommended they undergo annual breast MRI screening in addition to mammogram screening.
 

However, some women are finding that their insurer is refusing to cover the cost of the MRI.

A new study exploring this issue was presented at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer.

“Despite guidelines supporting annual breast MRI for screening in patients with gBRCA1/2, insurance denials were present in 11% of patients,” said lead author Sushmita Gordhandas, MD, a gynecologic oncology fellow at Memorial Sloan Kettering Cancer Center, New York. “In a high-resource setting, up to 14% of patients who were denied coverage did not undergo recommended MRI screening.”

She also pointed out that the rate of denials was rising. “Compared to 2020, there were significantly more denials, and denials on appeal, in 2021,” Dr. Gordhandas said. “This suggested worsening barriers and added burden on health care systems.”

The addition of MRI to mammography is a standard recommendation for women with BRCA mutations, she pointed out, as it has been shown improve detection of early disease and decrease interval cancer development.

An expert not involved in the study noted that the recommendation for annual MRI screening in women at high risk for breast cancer is “substantiated by many publications, including multiple prospective clinical trials.”

Linda Moy, MD, a radiologist at NYU Langone’s Perlmutter Cancer Center and professor of radiology at NYU Grossman School of Medicine, both in New York, noted that the American Cancer Society’s Guidelines for screening breast MRI recommends annual breast MRI in women with a lifetime risk of greater than 20% – which includes women who are BRCA carriers – and recommends the screening begins at age 30.

“The lifetime breast cancer risk is 72% among BRCA1 and 69% among BRCA2 carriers,” she said, adding that the “American College of Radiology also recommends for BRCA carriers to undergo annual screening MRI at age 30.”

The National Comprehensive Cancer Network recommends that women at high risk for breast cancer undergo a mammogram and breast MRI every year starting at age 25 to 40, depending on the type of gene mutation, noted Dr. Gordhandas. “These guidelines are consistent with those from American College of Obstetricians and Gynecologists, the American Cancer Society, and the American College of Radiology.”
 

Denials increased over time

For the study, Dr. Gordhandas and colleagues looked at the frequency of insurance denials for indicated breast MRI screening in women with germline BRCA1/2 pathogenic variants, and also looked at recent trends in denials over time.

The cohort comprised 682 women with BRCA1/2 gene mutations who were followed in a specialized high-risk breast cancer clinic, and who had breast MRIs ordered from 2020 to 2021. They were then cross-referenced with a database of insurance denials. Radiology records were also accessed to determine if screening breast MRIs had been performed in 2020 and 2021, and rates of MRI denials and results after appeals were determined. The rates between the 2 years were then compared.

The team found that overall, 73 women (11%) had an MRI denied. The median age of women who received a denial was 38 years, whereas those who had it approved was 44 years. “Patients with denials were significantly younger and more likely to be in the Medicaid population,” said Dr. Gordhandas.

In 2020, 29 breast MRIs (5%) were denied, and on appeal, 8 (28%) were denied and 21 (72%) approved. The number of denials rose in 2021 but approvals remained the same; 45 breast MRIs were denied (8%); on appeal, 23 (51%) were denied, and 22 (49%) approved.

Thus, noted the authors, there were significantly more denials in 2021 as compared with 2020 (P = .044), and the denials in 2021 denials were statistically more likely to be denied on appeal (P = .045).

Among the women whose coverage was denied, four (14%) in 2020 and five (11%) in 2021 did not have an MRI screening performed. And within this group, 17 women (2.5%) received a diagnosis of cancer; 12 (1.8%) had invasive carcinoma, and 5 (0.7%) had ductal carcinoma in situ (DCIS). One patient with DCIS had an MRI denial prior to receiving her diagnosis.

“The top reasons given for denials were that they were outside the approved time frame, authorization on file for a similar study, and that the clinician failed to show medical necessity,” she explained.

Additional data are needed to establish a trend. “We are working to increase the approval time frame, which is currently 45 days, and provide resources for the patient to deal with denials,” Dr. Gordhandas added. “We also have to advocate for updates to [U.S. Preventive Services Task Force] screening recommendations in high-risk patients.”

Dr. Gordhandas reported no relevant financial relationships.

“The top reasons given for denials were that they were outside the approved time frame, authorization on file for a similar study, and that the clinician failed to show medical necessity,” she explained.

Additional data are needed to establish a trend. “We are working to increase the approval time frame, which is currently 45 days, and provide resources for the patient to deal with denials,” Dr. Gordhandas added. “We also have to advocate for updates to [U.S. Preventive Services Task Force] screening recommendations in high-risk patients.”

Dr. Gordhandas reported no relevant financial relationships.

Jake Warn calls vaping “a toxic artificial love.”

Jake, of Winslow, Maine, was 16 years old when he began vaping. Unlike cigarettes, vaping can be odorless, and its smoke leaves no trace, which allowed him and his friends to use the devices in school bathrooms without fear of being caught.

He would use an entire cartridge containing the vape liquid, the equivalent of smoking one pack of tobacco cigarettes, within 1 school day. By the fall semester of his first year in college, Jake said his use had increased even more.

“It got pricey, so that’s when I really started to notice” the extent of his dependency, he said recently.

Vaping rates among teenagers in Maine doubled from 15.3% to 28.7% between 2017 and 2019, while Jake was in high school. In 2021, 11% of high schoolers across the nation said they regularly smoked e-cigarettes, and an estimated 28% have ever tried the devices, according to the Centers for Disease Control and Prevention.

The Food and Drug Administration classifies e-cigarettes as a tobacco product because many contain nicotine, which comes from tobacco. Like Jake, the habit is likely to carry into adulthood for many who start in their teenage years, experts say.

Electronic nicotine delivery systems (ENDS) such as vapes have been touted by their manufacturers and by some in the medical field as a healthier alternative to cigarettes and as a method to help smokers give up the habit.

But, that’s not how Jake – who had never used combustible cigarettes – picked up vaping, or how he sold the idea to his mother.

“It’s all organic and natural flavoring, it’s just flavored water,” Mary Lou Warn recalled her son saying to her. She researched the health effects of vaping but didn’t find much online. “I knew they were dangerous because you don’t put anything in your lungs that isn’t fresh air.”

A determined athlete in high school, Jake found that his asthma worsened as he transitioned to college, especially when he ran a track meet or during a soccer game.

Mrs. Warn noticed changes off the field, too.

“He was coughing constantly, he wasn’t sleeping well, he wasn’t eating well,” she said. “I knew the addiction was taking over.”

Vaping irritated Jake’s throat, and he would get nosebleeds that he couldn’t stop, she added.

Since Mrs. Warn first looked into the effects of e-cigarettes on respiratory health back in 2017, many studies have been conducted of the short-term health outcomes for first-time smokers who never used combustible tobacco products. Studies suggest that vaping may worsen bronchitis and asthma, raise blood pressure, interfere with brain development in young users, suppress the immune system, and increase the risk of developing a chronic lung disease (Am J Prev Med. 2020 Feb;58[2]:182-90). Studies of mice and cell cultures have found that the vapor or extracts from vapes damage the chemical structure of DNA.

Still, the limited number of long-term human studies has made it hard to know what the health outcomes of e-cigarette users will be in the future. Conclusive studies linking commercial cigarette use to deaths from heart disease and cancer didn’t emerge until the mid-1950s, decades after manufacturers began mass production and marketing in the early 20th century.

Years could pass before researchers gain a clearer understanding of the health implications of long-term e-cigarette use, according to Nigar Nargis, PhD, senior scientific director of tobacco control research at the American Cancer Society.

“There hasn’t been any such study to establish the direct link from ENDS to cancer, but it is understood that it [vaping] may promote the development of cancer and lung damage and inflammation,” Dr. Nargis said.

For decades, advocates built awareness of the harms of tobacco use, which led to a sharp decline in tobacco-related illnesses such as lung cancer. But Hilary Schneider, Maine’s director of government relations for the ACS Cancer Action Network, said she fears the uptick in the use of vapes – especially among those who never smoked or those who use both combustible cigarettes and e-cigarettes – may reverse declines in the rates of smoking-relating diseases.

Multiple studies suggest that inhaling chemicals found in e-cigarettes – including nicotine-carrying aerosols – can damage arteries and inflame and injure the lungs.

Vapes “basically have created a pediatric tobacco-use epidemic,” Ms. Schneider said. “What we’re seeing is unprecedented tobacco use rates, higher rates than we’ve seen in decades.”

One reason many young people start vaping is the attraction to flavors, which range from classic menthol to fruits and sweets. A handful of states have enacted bans or restrictions on the sale of flavored vapes.

“It’s new, and it’s just been marketed in a way that we’re really fighting the false narrative put out there by makers of these products that are trying to make them appealing to kids,” said Rachel Boykan, MD, clinical professor of pediatrics and attending physician at Stony Brook (N.Y.) Children’s Hospital.

The flavor Red Bull, in particular, hooked Jake. And though he wasn’t aware of it at the time, nicotine packed into the pods may have kept him from quitting: The average nicotine concentration in e-cigarettes more than doubled from 2013 to 2018, according to a study by the Truth Initiative and the CDC.

The immediate risks of nicotine on the developing brain are well documented. Studies suggest that nicotine – which is found in ENDS products – may affect adolescents’ ability to learn, remember, and maintain attention.

But many adolescents and young adults who use e-cigarettes say that vaping helps alleviate anxiety and keep them attentive, which adds to the complexity of their dependency, according to Dr. Boykan.

Nicotine “actually interrupts neural circuits, that it can be associated with more anxiety, depression, attention to learning, and susceptibility to other addictive substances,” she said. “That is enough to make it very scary.”

Jake also said a social environment in which so many of his friends vaped also made it difficult for him to quit.

“You’re hanging out with your friends at night, and all of them are using it, and you’re trying not to,” he said.

Jake eventually took a semester off from college for an unrelated surgery. He moved home, away from his vaping classmates. He eventually transferred to a different college and lived at home, where no one vaped and where he wasn’t allowed to smoke in the house, he said.

“He came home and we took him to a doctor, and they didn’t know quite how to handle kids and addiction to e-cigarettes,” Mrs. Warn said.

Not fully understanding the long-term health implications of e-cigarette use has precluded many clinicians from offering clear messaging on the risk of vaping to current and potential users.

“It’s taken pediatricians time to ask the right questions and recognize nicotine addiction” from vaping, said Dr. Boykan, who serves as chair of the Section on Nicotine and Tobacco Prevention and Treatment of the American Academy of Pediatrics. “It’s just hit us so fast.”

But once pediatricians do identify a nicotine dependency, it can be difficult to treat, Dr. Boykan said. Many pediatricians now recognize that e-cigarette addiction may occur in children as early as middle school.

“We don’t have a lot of evidence-based treatments for kids to recommend,” Dr. Boykan said.
 

Will vaping be a ‘phase?’

Aware of his vaping dependency and the possible risks to his long-term health, Jake, now 23, said he’s lessened his use, compared with his college days, but still struggles to kick the habit for good.

“I’d like to not be able to use all the time, not to feel the urge,” Jake said. “But I think over time it’ll just kind of phase out.”

But his mother said quitting may not be that simple.

“This will be a lifelong journey,” she said. “When I think of who he is, addiction is something he will always have. It’s a part of him now.”

Dr. Boykan, Ms. Schneider, and Dr. Nardis reported no relevant financial disclosures.

An alpha-synuclein seed amplification assay (αSyn-SAA) accurately identifies people with Parkinson’s disease, as well as those at risk for Parkinson’s disease and those with early, prodromal symptoms, and provides information on molecular subtypes, new research indicates.

“Identifying an effective biomarker for Parkinson’s disease pathology could have profound implications for the way we treat the condition, potentially making it possible to diagnose people earlier, identify the best treatments for different subsets of patients, and speed up clinical trials,” the study’s co-lead author Andrew Siderowf, MD, of the University of Pennsylvania, Philadelphia, said in a news release.

“Our findings suggest that the αSyn-SAA technique is highly accurate at detecting the biomarker for Parkinson’s disease regardless of the clinical features, making it possible to accurately diagnose the disease in patients at early stages,” added co-lead author Luis Concha-Marambio, PhD, director of research and development at Amprion, San Diego, Calif.

The study was published online in The Lancet Neurology.
 

‘New era’ in Parkinson’s disease

The researchers assessed the usefulness of αSyn-SAA in a cross-sectional analysis of 1,123 participants in the Parkinson’s Progression Markers Initiative (PPMI) cohort from 33 participating academic neurology outpatient practices in 12 countries.

The cohort included individuals with sporadic Parkinson’s disease from LRRK2 or GBA variants, healthy controls, individuals with clinical syndromes prodromal to Parkinson’s disease (rapid eye movement sleep behavior disorder [RBD] or hyposmia), and nonmanifesting carriers of LRRK2 and GBA variants. Cerebrospinal fluid (CSF) samples from each participant were analyzed using αSyn-SAA.

Overall, αSyn-SAA differentiated Parkinson’s disease from healthy controls with 87.7% sensitivity and 96.3% specificity.

Sensitivity of the assay varied across subgroups based on genetic and clinical features. Among genetic Parkinson’s disease subgroups, sensitivity was highest for GBA Parkinson’s disease (95.9%), followed by sporadic Parkinson’s disease (93.3%), and lowest for LRRK2 Parkinson’s disease (67.5%). Among clinical features, hyposmia was the most robust predictor of a positive assay result.

Among all Parkinson’s disease cases with hyposmia, the sensitivity of the assay was 97.2%, compared with 63.0% for Parkinson’s disease without olfactory dysfunction. Combining genetic and clinical features, the sensitivity of positive αSyn-SAA in sporadic Parkinson’s disease with olfactory deficit was 98.6%, compared with 78.3% in sporadic Parkinson’s disease without hyposmia. Most prodromal participants (86%) with RBD and hyposmia had positive αSyn-SAA results, indicating they had α-synuclein aggregates despite not yet being diagnosed with Parkinson’s disease.

Among those recruited based on their loss of smell, 89% (16 of 18 participants) had positive αSyn-SAA results. Similarly, in those with RBD, positive αSyn-SAA results were present in 85% of cases (28 of 33). No other clinical features were associated with a positive αSyn-SAA result.

In participants who carried LRRK2 or GBA variants but had no Parkinson’s disease diagnosis or prodromal symptoms (nonmanifesting carriers), 9% (14 of 159) and 7% (11 of 151), respectively, had positive αSyn-SAA results.

To date, this is the largest analysis of α-Syn-SAA for the biochemical diagnosis of Parkinson’s disease, the researchers said.

The results show that the assay classifies people with Parkinson’s disease with “high sensitivity and specificity, provides information about molecular heterogeneity, and detects prodromal individuals before diagnosis,” they wrote.

“These findings suggest a crucial role for the α-synuclein SAA in therapeutic development, both to identify pathologically defined subgroups of people with Parkinson’s disease and to establish biomarker-defined at-risk cohorts,” they added.

Amprion has commercialized the assay (SYNTap test), which can be ordered online.
 

‘Seminal development’

The authors of an accompanying editorial noted the study “lays the foundation for a biological diagnosis” of Parkinson’s disease. “We have entered a new era of biomarker and treatment development for Parkinson’s disease. The possibility of detecting a misfolded α-synuclein, the pathological hallmark of Parkinson’s disease, by employing an SSA, is a seminal development,” wrote Daniela Berg, MD, PhD, and Christine Klein, MD, with University Hospital Schleswig-Holstein, Germany.

“However, to fully leverage the enormous potential of the α-synuclein seed amplification, the test would have to be performed in blood rather than the CSF, a less invasive approach that has proven to be viable,” they added.

“Although the blood-based method needs to be further elaborated for scalability, α-synuclein SAA is a game changer in Parkinson’s disease diagnostics, research, and treatment trials,” they concluded.

The study was funded by The Michael J. Fox Foundation for Parkinson’s Research and a consortium of more than 40 private and philanthropic partners. Dr. Siderowf has declared consulting for Merck and Parkinson Study Group, and receiving honoraria from Bial. A full list of author disclosures is available with the original article.

The possibility of detecting a misfolded α-synuclein, the pathological hallmark of Parkinson’s disease, by employing an SSA, is a seminal development,” wrote Daniela Berg, MD, PhD, and Christine Klein, MD, with University Hospital Schleswig-Holstein, Germany.

“However, to fully leverage the enormous potential of the α-synuclein seed amplification, the test would have to be performed in blood rather than the CSF, a less invasive approach that has proven to be viable,” they added.

“Although the blood-based method needs to be further elaborated for scalability, α-synuclein SAA is a game changer in Parkinson’s disease diagnostics, research, and treatment trials,” they concluded.

The study was funded by The Michael J. Fox Foundation for Parkinson’s Research and a consortium of more than 40 private and philanthropic partners.

An alpha-synuclein seed amplification assay (αSyn-SAA) accurately identifies people with Parkinson’s disease, as well as those at risk for Parkinson’s disease and those with early, prodromal symptoms, and provides information on molecular subtypes, new research indicates.

“Identifying an effective biomarker for Parkinson’s disease pathology could have profound implications for the way we treat the condition, potentially making it possible to diagnose people earlier, identify the best treatments for different subsets of patients, and speed up clinical trials,” the study’s co-lead author Andrew Siderowf, MD, of the University of Pennsylvania, Philadelphia, said in a news release.

“Our findings suggest that the αSyn-SAA technique is highly accurate at detecting the biomarker for Parkinson’s disease regardless of the clinical features, making it possible to accurately diagnose the disease in patients at early stages,” added co-lead author Luis Concha-Marambio, PhD, director of research and development at Amprion, San Diego, Calif.

The study was published online in The Lancet Neurology.
 

‘New era’ in Parkinson’s disease

The researchers assessed the usefulness of αSyn-SAA in a cross-sectional analysis of 1,123 participants in the Parkinson’s Progression Markers Initiative (PPMI) cohort from 33 participating academic neurology outpatient practices in 12 countries.

The cohort included individuals with sporadic Parkinson’s disease from LRRK2 or GBA variants, healthy controls, individuals with clinical syndromes prodromal to Parkinson’s disease (rapid eye movement sleep behavior disorder [RBD] or hyposmia), and nonmanifesting carriers of LRRK2 and GBA variants. Cerebrospinal fluid (CSF) samples from each participant were analyzed using αSyn-SAA.

Overall, αSyn-SAA differentiated Parkinson’s disease from healthy controls with 87.7% sensitivity and 96.3% specificity.

Sensitivity of the assay varied across subgroups based on genetic and clinical features. Among genetic Parkinson’s disease subgroups, sensitivity was highest for GBA Parkinson’s disease (95.9%), followed by sporadic Parkinson’s disease (93.3%), and lowest for LRRK2 Parkinson’s disease (67.5%). Among clinical features, hyposmia was the most robust predictor of a positive assay result.

Among all Parkinson’s disease cases with hyposmia, the sensitivity of the assay was 97.2%, compared with 63.0% for Parkinson’s disease without olfactory dysfunction. Combining genetic and clinical features, the sensitivity of positive αSyn-SAA in sporadic Parkinson’s disease with olfactory deficit was 98.6%, compared with 78.3% in sporadic Parkinson’s disease without hyposmia. Most prodromal participants (86%) with RBD and hyposmia had positive αSyn-SAA results, indicating they had α-synuclein aggregates despite not yet being diagnosed with Parkinson’s disease.

Among those recruited based on their loss of smell, 89% (16 of 18 participants) had positive αSyn-SAA results. Similarly, in those with RBD, positive αSyn-SAA results were present in 85% of cases (28 of 33). No other clinical features were associated with a positive αSyn-SAA result.

In participants who carried LRRK2 or GBA variants but had no Parkinson’s disease diagnosis or prodromal symptoms (nonmanifesting carriers), 9% (14 of 159) and 7% (11 of 151), respectively, had positive αSyn-SAA results.

To date, this is the largest analysis of α-Syn-SAA for the biochemical diagnosis of Parkinson’s disease, the researchers said.

The results show that the assay classifies people with Parkinson’s disease with “high sensitivity and specificity, provides information about molecular heterogeneity, and detects prodromal individuals before diagnosis,” they wrote.

“These findings suggest a crucial role for the α-synuclein SAA in therapeutic development, both to identify pathologically defined subgroups of people with Parkinson’s disease and to establish biomarker-defined at-risk cohorts,” they added.

Amprion has commercialized the assay (SYNTap test), which can be ordered online.

Food insecurity is linked to a more rapid decline in executive function in older adults, a new study shows.

The findings were reported just weeks after a pandemic-era expansion in Supplemental Nutrition Assistance Program benefits ended, leading to less food assistance for about 5 million people over age 60 who participate in the program.

“Even though we found only a very small association between food insecurity and executive function, it’s still meaningful, because food insecurity is something we can prevent,” lead investigator Boeun Kim, PhD, MPH, RN, postdoctoral fellow at Johns Hopkins University School of Nursing, Baltimore, told this news organization.

The findings were published online  in JAMA Network Open.
 

National data

The number of Americans over 60 with food insecurity has more than doubled since 2007, with an estimated 5.2 million older adults reporting food insecurity in 2020.

Prior studies have linked malnutrition and food insecurity to a decline in cognitive function. Participating in food assistance programs such as SNAP is associated with slower memory decline in older adults.

However, to date, there has been no longitudinal study that has used data from a nationally representative sample of older Americans, which, Dr. Kim said, could limit generalizability of the findings.

To address that issue, investigators analyzed data from 3,037 participants in the National Health and Aging Trends Study, which includes community dwellers age 65 and older who receive Medicare.

Participants reported food insecurity over 7 years, from 2012 to 2019. Data on immediate memory, delayed memory, and executive function were from 2013 to 2020.

Food insecurity was defined as going without groceries due to limited ability or social support; a lack of hot meals related to functional limitation or no help; going without eating because of the inability to feed oneself or no available support; skipping meals due to insufficient food or money; or skipping meals for 5 days or more.

Immediate and delayed recall were assessed using a 10-item word-list memory task, and executive function was measured using a clock drawing test. Each year’s cognitive functions were linked to the prior year’s food insecurity data.

Over 7 years, 417 people, or 12.1%, experienced food insecurity at least once.

Those with food insecurity were more likely to be older, female, part of racial and ethnic minority groups, living alone, obese, and have a lower income and educational attainment, depressive symptoms, social isolation and disability, compared with those without food insecurity.

After adjusting for age, sex, race/ethnicity, educational level, income, marital status, body mass index, functional disability, social isolation, and other potential confounders, researchers found that food insecurity was associated with a more rapid decline in executive function (mean difference in annual change in executive function score, −0.04; 95% confidence interval, −0.09 to −0.003).

Food insecurity was not associated with baseline cognitive function scores or changes in immediate or delayed recall.

“Clinicians should be aware of the experience of food insecurity and the higher risk of cognitive decline so maybe they could do universal screening and refer people with food insecurity to programs that can help them access nutritious meals,” Dr. Kim said.
 

A sign of other problems?

Thomas Vidic, MD, said food insecurity often goes hand-in-hand with lack of medication adherence, lack of regular medical care, and a host of other issues. Dr. Vidic is a neurologist at the Elkhart Clinic, Ind., and an adjunct clinical professor of neurology at Indiana University.

“When a person has food insecurity, they likely have other problems, and they’re going to degenerate faster,” said Dr. Vidic, who was not part of the study. “This is one important component, and it’s one more way of getting a handle on people who are failing.”

Dr. Vidic, who has dealt with the issue of food insecurity with his own patients, said he suspects the self-report nature of the study may hide the true scale of the problem.

“I suspect the numbers might actually be higher,” he said, adding that the study fills a gap in the literature with a large, nationally representative sample.

“We’re looking for issues to help with the elderly as far as what can we do to keep dementia from progressing,” he said. “There are some things that make sense, but we’ve never had this kind of data before.”

The study was funded by the National Institute on Aging. Dr. Kim and Dr. Vidic have reported no relevant financial relationships.

Findings from a landmark clinical trial in pediatric Crohn’s disease show a clear benefit of adding methotrexate to treatment with the tumor necrosis factor inhibitor (TNFi) adalimumab (Humira) but not to infliximab therapy.

Children initiating treatment with adalimumab plus a low dose of methotrexate experienced a twofold reduction in treatment failure, note the authors of the largest, double-blind, randomized trial to date in pediatric Crohn’s disease. However, children initiating infliximab, another TNFi, had similar outcomes with or without methotrexate.

“We believe these results are practice-changing,” said principal investigator Michael Kappelman, MD, MPH, professor of pediatrics at University of North Carolina, Chapel Hill.

All patients with pediatric Crohn’s disease starting on adalimumab and their parents should be informed that combining the drug with low-dose oral methotrexate improves treatment effectiveness, he said.

“Those without contraindications should be offered combination therapy, and shared decision-making should be incorporated into final treatment decisions. In contrast, most patients starting infliximab are not likely to experience added benefits from low-dose oral methotrexate,” Dr. Kappelman added.

The study was published online  in Gastroenterology and will be presented in early May at Digestive Disease Week® 2023.

Impactful study

“This is an important study, published in a very high-ranking journal, that will have a huge impact on how we practice,” said Jacob Kurowski, MD, department of pediatric gastroenterology, hepatology, and nutrition, Cleveland Clinic Children’s, who wasn’t involved in the study.

Treatment with a TNFi, including infliximab and adalimumab, is a mainstay of pediatric Crohn’s disease therapy. However, not all patients achieve remission, and many lose response over time.

The current trial compared the effectiveness and safety of adding a low-dose of oral methotrexate to adalimumab or infliximab versus TNFi therapy alone in 297 children with Crohn’s disease.

The mean age was 13.9 years, and about two-thirds were boys. None had a prior history of TNFi therapy.

Participants initiating infliximab or adalimumab were randomly allocated (1:1) to oral methotrexate or placebo. Of them, 110 infliximab initiators and 46 adalimumab initiators received methotrexate, while 102 infliximab initiators and 39 adalimumab initiators were given placebo. Methotrexate was administered as a weekly dose of 15 mg for children weighing 40 kg or more, 12.5 mg for children 30 to less than 40 kg, and 10 mg for children 20 to less than 30 kg. All participants received pretreatment with ondansetron 4 mg (or placebo) to prevent nausea and folic acid (1 mg per day). Participants were followed for 12-36 months.

The primary outcome was a failure to achieve or maintain steroid-free remission defined by occurrence of any of the following.

• Short Pediatric Crohn’s Disease Activity Index score of less than 15 by week 26
• Failure to complete a steroid taper by week 16
• SPCDAI score of 15 or higher as a result of active Crohn’s disease at two or more consecutive visits beyond week 26
• Hospitalization or surgery for Crohn’s disease beyond week 26
• Use of corticosteroids for Crohn’s disease for 10 or more weeks cumulatively beyond week 16
• Discontinuation of anti-TNF and/or study drug for lack of effectiveness or toxicity

Overall, 88 of 297 children (30%) experienced treatment failure, including 57 of 212 (27%) on infliximab and 31 of 85 (36%) on adalimumab. Overall, 40 of 156 children (26%) on combination therapy and 48 of 141 (34%) on monotherapy experienced treatment failure.

Kaplan Meier analysis of the overall population showed a nonsignificant trend toward lower event rates with combination therapy (hazard ratio, 0.69; 95% confidence interval, 0.45-1.05; P = .08).

After stratification by TNFi, there was no difference in time to treatment failure among infliximab initiators between combination and monotherapy (HR, 0.93; 95% CI, 0.55-1.56; P = .78). In contrast, among adalimumab initiators, combination therapy was significantly associated with a longer time to treatment failure (HR, 0.40; 95% CI, 0.19-0.81; P = .01).

There was a nonsignificant trend toward lower development of anti-drug antibodies with combination therapy (risk ratio, 0.72 with infliximab and 0.71 with adalimumab). This trend is in line with adult studies and adds substantially to the pediatric literature on this topic, the researchers noted.

No differences in patient-reported outcomes were observed. There were slightly more adverse events with combination therapy, as expected, but fewer serious adverse events.
 

Shared decision-making

Dr. Kappelman noted that the study was not designed to answer the question of which is better – adalimumab plus methotrexate or infliximab alone. “This is an area for future research. At this point, we believe it is an individualized decision, and appropriate counseling is needed to support shared decision-making,” he said.

Nor was the trial designed to evaluate the role of proactive therapeutic drug monitoring. However, proactive TDM is endorsed in the ImproveCareNow Model IBD Care guidelines and was considered standard of care at the 35 study sites.

The findings “suggest strong consideration of using combination therapy for pediatric Crohn’s disease patients initiating adalimumab but not infliximab,” Dr. Kappelman and colleagues said.

“Dissemination and implementation of these findings should lead to improved outcomes in this patient population, including consideration of de-implementation of combination therapy in infliximab treated patients,” they added.

The decision about which approach to use is still very dependent on patients and their providers, Dr. Kurowski said.

“The study shows that you can safely use infliximab as monotherapy, with low risk of antibody formation, while utilizing proactive therapeutic drug monitoring and dose optimization. The study also shows that adalimumab in combination with low-dose methotrexate can be strongly considered when needed.”

The researchers’ standardization of methotrexate doses by weight “is another significant contribution and provides a guide for clinicians,” Dr. Kurowski added.

The study was funded by grants from the Patient-Centered Outcomes Research Institute, the Helmsley Charitable Trust, and National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Kappelman has consulted for AbbVie, Janssen, Pfizer, Takeda, and Lilly; holds shares in Johnson & Johnson; and has received research support from Pfizer, Takeda, Janssen, AbbVie, Lilly, Genentech, Boehringer Ingelheim, Bristol-Myers Squibb, Celtrion, and Arena Pharmaceuticals. Dr. Kurowski reports no relevant financial relationships.

“Those without contraindications should be offered combination therapy, and shared decision-making should be incorporated into final treatment decisions. In contrast, most patients starting infliximab are not likely to experience added benefits from low-dose oral methotrexate,” Dr. Kappelman added.

The study was published online  in Gastroenterology and will be presented in early May at Digestive Disease Week® 2023.

Impactful study

“This is an important study, published in a very high-ranking journal, that will have a huge impact on how we practice,” said Jacob Kurowski, MD, department of pediatric gastroenterology, hepatology, and nutrition, Cleveland Clinic Children’s, who wasn’t involved in the study.

Treatment with a TNFi, including infliximab and adalimumab, is a mainstay of pediatric Crohn’s disease therapy. However, not all patients achieve remission, and many lose response over time.

The current trial compared the effectiveness and safety of adding a low-dose of oral methotrexate to adalimumab or infliximab versus TNFi therapy alone in 297 children with Crohn’s disease.

The mean age was 13.9 years, and about two-thirds were boys. None had a prior history of TNFi therapy.

Participants initiating infliximab or adalimumab were randomly allocated (1:1) to oral methotrexate or placebo. Of them, 110 infliximab initiators and 46 adalimumab initiators received methotrexate, while 102 infliximab initiators and 39 adalimumab initiators were given placebo. Methotrexate was administered as a weekly dose of 15 mg for children weighing 40 kg or more, 12.5 mg for children 30 to less than 40 kg, and 10 mg for children 20 to less than 30 kg. All participants received pretreatment with ondansetron 4 mg (or placebo) to prevent nausea and folic acid (1 mg per day). Participants were followed for 12-36 months.

The primary outcome was a failure to achieve or maintain steroid-free remission defined by occurrence of any of the following.

• Short Pediatric Crohn’s Disease Activity Index score of less than 15 by week 26
• Failure to complete a steroid taper by week 16
• SPCDAI score of 15 or higher as a result of active Crohn’s disease at two or more consecutive visits beyond week 26
• Hospitalization or surgery for Crohn’s disease beyond week 26
• Use of corticosteroids for Crohn’s disease for 10 or more weeks cumulatively beyond week 16
• Discontinuation of anti-TNF and/or study drug for lack of effectiveness or toxicity

Overall, 88 of 297 children (30%) experienced treatment failure, including 57 of 212 (27%) on infliximab and 31 of 85 (36%) on adalimumab. Overall, 40 of 156 children (26%) on combination therapy and 48 of 141 (34%) on monotherapy experienced treatment failure.

Kaplan Meier analysis of the overall population showed a nonsignificant trend toward lower event rates with combination therapy (hazard ratio, 0.69; 95% confidence interval, 0.45-1.05; P = .08).

After stratification by TNFi, there was no difference in time to treatment failure among infliximab initiators between combination and monotherapy (HR, 0.93; 95% CI, 0.55-1.56; P = .78). In contrast, among adalimumab initiators, combination therapy was significantly associated with a longer time to treatment failure (HR, 0.40; 95% CI, 0.19-0.81; P = .01).

There was a nonsignificant trend toward lower development of anti-drug antibodies with combination therapy (risk ratio, 0.72 with infliximab and 0.71 with adalimumab). This trend is in line with adult studies and adds substantially to the pediatric literature on this topic, the researchers noted.

No differences in patient-reported outcomes were observed. There were slightly more adverse events with combination therapy, as expected, but fewer serious adverse events.
 

Shared decision-making

Dr. Kappelman noted that the study was not designed to answer the question of which is better – adalimumab plus methotrexate or infliximab alone. “This is an area for future research. At this point, we believe it is an individualized decision, and appropriate counseling is needed to support shared decision-making,” he said.

Nor was the trial designed to evaluate the role of proactive therapeutic drug monitoring. However, proactive TDM is endorsed in the ImproveCareNow Model IBD Care guidelines and was considered standard of care at the 35 study sites.

The findings “suggest strong consideration of using combination therapy for pediatric Crohn’s disease patients initiating adalimumab but not infliximab,” Dr. Kappelman and colleagues said.

“Dissemination and implementation of these findings should lead to improved outcomes in this patient population, including consideration of de-implementation of combination therapy in infliximab treated patients,” they added.

The decision about which approach to use is still very dependent on patients and their providers, Dr. Kurowski said.

“The study shows that you can safely use infliximab as monotherapy, with low risk of antibody formation, while utilizing proactive therapeutic drug monitoring and dose optimization. The study also shows that adalimumab in combination with low-dose methotrexate can be strongly considered when needed.”

The researchers’ standardization of methotrexate doses by weight “is another significant contribution and provides a guide for clinicians,” Dr. Kurowski added.

The study was funded by grants from the Patient-Centered Outcomes Research Institute, the Helmsley Charitable Trust, and National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Kappelman has consulted for AbbVie, Janssen, Pfizer, Takeda, and Lilly; holds shares in Johnson & Johnson; and has received research support from Pfizer, Takeda, Janssen, AbbVie, Lilly, Genentech, Boehringer Ingelheim, Bristol-Myers Squibb, Celtrion, and Arena Pharmaceuticals. Dr. Kurowski reports no relevant financial relationships.

Early parathyroidectomy within 1 year of diagnosis of primary hyperparathyroidism (PHPT) did not reduce the risk of a sustained decline in kidney function, measured by a decline in estimated glomerular filtration rate (eGFR) of at least 50%, compared with observation (no surgery) in adults aged 60 and older.

Early parathyroidectomy was, however, associated with a reduced adjusted risk of this decline in kidney function in patients with newly diagnosed PHPT who were younger than age 60.

The findings, based on data from close to 43,000 veterans, were published online in Annals of Internal Medicine.

“The important takeaway from our study is that for older adults [age 60 or older] with primary hyperparathyroidism, preservation of kidney function should not be a primary consideration when making decisions about whether to undergo parathyroidectomy,” lead author Carolyn D. Seib, MD, told this news organization.

“It is important that physicians also discuss with their patients the potential long-term benefits of parathyroidectomy related to a reduced risk of fractures, kidney stones, and cardiovascular disease, and improved quality of life, in addition to the need for lifelong surveillance if surgery is declined, weighing these against an individual patient’s risk of surgery,” said Dr. Seib, a surgeon at Palo Alto (Calif.) VA Medical Center.

“However, in patients younger than 60, early parathyroidectomy may prevent progression to chronic kidney disease (CKD) and should be more strongly considered,” she noted.

Parathyroidectomy, she observed, is a low-risk outpatient surgery for most adults.

“Potential complications of surgery include temporary or permanent hoarseness, hypoparathyroidism (low postoperative parathyroid function), bleeding requiring return to the operating room, and complications related to general anesthesia, all of which are rare,” said Dr. Seib.

“Surgery by a high-volume surgeon is associated with a reduced risk of complications, so patients should seek out an experienced parathyroid surgeon,” she emphasized.  

Moreover, parathyroidectomy is the only treatment for primary hyperparathyroidism.
 

Does parathyroidectomy slow loss of kidney function?

Multidisciplinary guidelines recommend parathyroidectomy, at least in part to mitigate the risk for, and effects related to, the progression of CKD in patients with PHPT and an eGFR below 60 mL/min per 1.73 m², the researchers wrote.

However, whether parathyroidectomy slows the loss of kidney function in adults with PHPT is not clear.

Guidelines also state that “observation for PHPT disease progression can be considered when patients have no obvious end organ damage (i.e., eGFR > 60 mL/min per 1.73 m², normal bone mineral density, and no history of kidney stones or fractures),” Dr. Seib noted.  

To address the evidence gap, the researchers emulated a randomized target trial using observational data.

In this type of study, Dr. Seib explained, “although patients aren’t randomly assigned to a treatment, complex statistical methods are used to adjust for baseline confounders in an attempt to emulate random treatment assignment and account for bias that may affect the timing of when patients receive treatment.”

Using national Veterans Health Administration data, researchers identified 43,697 veterans with a new biochemical diagnosis of PHPT, defined as elevated parathyroid hormone (> 65 ng/mL) within 6 months of an elevated serum calcium level (> 32.55 mmol/L or >10.2 mg/dL), from 2000 to 2019.

Of these patients, 3,804 underwent parathyroidectomy within 1 year of diagnosis of PHPT, and 39,893 did not, and instead, a watchful waiting approach was adopted.

To be included in the analysis, patients had to have an eGFR above 30 mL/min per 1.73 m² for 12 months before PHPT diagnosis to exclude secondary or tertiary hyperparathyroidism.

The primary outcome was a sustained decline in eGFR of at least 50% from baseline.

In the overall cohort, patients had a mean pretreatment eGFR of 71.8 mL/min per 1.73 m². The mean age of patients was 67, 88% were men, and 68% were White.

After a median follow-up of 4.9 years, 6.7% of the patients had a decline in eGFR of at least 50%.

The cumulative incidence of this decline in eGFR was 5.1% at 5 years and 10.8% at 10 years in patients who had had early parathyroidectomy compared with 5.1% and 12.0%, respectively, in patients who did not undergo surgery.

In the overall population, the risk of at least a 50% decline in eGFR was similar in the early parathyroidectomy group versus the observation group (adjusted hazard ratio [HR], 0.98, 95% confidence interval [CI], 0.82-1.16).

However, diving deeper showed that parathyroidectomy was associated with a reduced risk of the primary outcome among patients younger than 60 years (adjusted HR, 0.75, 95% CI, 0.59-0.93) but not among those aged 60 or older (adjusted HR, 1.08, 95% CI, 0.87-1.34).

“When participating in shared decision-making for older adults [age 60 and older] with PHPT, clinicians should not consider parathyroidectomy for potential benefits of preservation of kidney function,” the researchers reiterated.

“For younger patients, clinicians should discuss the potential benefit of parathyroidectomy to reduce the risk for CKD and associated complications in adults with PHPT,” they concluded.

The study was funded by the National Institute on Aging. The authors reported no relevant financial relationships.
