Pediatrics

Children born to mothers in poor cardiovascular health during pregnancy had an almost eight times higher risk for landing in the poorest cardiovascular health category in early adolescence than children born to mothers who had ideal cardiovascular health during pregnancy.

In an observational cohort study that involved 2,302 mother-child dyads, 6.0% of mothers and 2.6% of children were considered to be in the poorest category of cardiovascular health on the basis of specific risk factors.

The children of mothers with any “intermediate” cardiovascular health metrics in pregnancy – for example, being overweight but not obese – were at just more than two times higher risk for poor cardiovascular health in early adolescence.

Although acknowledging the limitations of observational data, Amanda M. Perak, MD, Northwestern University, Chicago, suggested that focusing on whether or not the relationships seen in this study are causal might be throwing the baby out with the bathwater.

“I would suggest that it may not actually matter whether there is causality or correlation here, because if you can identify newborns at birth who have an eight times higher risk for poor cardiovascular health in childhood based on mom’s health during pregnancy, that’s valuable information either way,” said Dr. Perak.

“Even if you don’t know why their risk is elevated, you might be able to target those children for more intensive preventative efforts throughout childhood to help them hold on to their cardiovascular health for longer.”

That said, she thinks it’s possible that the intrauterine environment might actually directly affect offspring health, either through epigenetics modifications to cardiometabolic regulatory genes or possibly through actual organ development. Her group is collecting epigenetic data to study this further.

“We also need to do a study to see if intervening during pregnancy with mothers leads to better cardiovascular health in offspring, and that’s a question we can answer with a clinical trial,” said Dr. Perak.

This study was published on Feb. 16, 2021, in JAMA.
 

Equal footing

“We’ve always talked about cardiovascular health as if everyone is born with ideal cardiovascular health and loses it from there, and I think what this article points out is that not everybody starts on equal footing,” said Stephen R. Daniels, MD, PhD, University of Colorado at Denver, Aurora, who wrote an editorial accompanying the study.

“We need to start upstream, working with mothers before and during pregnancy, but it’s also important to understand, from a pediatric standpoint, that with some of these kids the horse is kind of already out of the barn very early.”

Dr. Daniels is pediatrician in chief and chair of pediatrics at Children’s Hospital Colorado in Aurora.

This study is the first to examine the relevance of maternal gestational cardiovascular health to offspring cardiovascular health and an important first step toward developing new approaches to address the concept of primordial prevention, he said.

“If primary prevention is identifying risk factors and treating them, I think of primordial prevention as preventing the development of those risk factors in the first place,” said Dr. Daniels.

Future trials, he added, should focus on the various mechanistic pathways – biological effects, shared genetics, and lifestyle being the options – to better understand opportunities for intervention.
 

Mother-child pairs

Dr. Perak and colleagues used data from the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) study and the HAPO Follow-up Study.

Participants were 2,302 mother-child pairs from nine field centers in Barbados, Canada, China, Thailand, United Kingdom, and the United States, and represented a racially and ethnically diverse cohort.

The mean ages were 29.6 years for pregnant mothers and 11.3 years for children. The pregnancies occurred between 2000 and 2006, and the children were examined from 2013 to 2016, when the children were aged 10-14 years.

Using the American Heart Association’s definition of cardiovascular health, the scientists categorized pregnancy health for mothers based on their measures of body mass index, blood pressure, total cholesterol, glucose level, and smoking status at 28 weeks’ gestation. These five metrics of gestational cardiovascular health have been significantly associated with adverse pregnancy outcomes.

They categorized cardiovascular health for offspring at age 10-14 years based on four of these five metrics: body mass index, blood pressure, cholesterol, and glucose.

Only 32.8% of mothers and 42.2% of children had ideal cardiovascular health.

In analyses adjusted for pregnancy and birth outcomes, the associations seen between poor gestational maternal health and offspring cardiovascular health persisted but were attenuated.

Dr. Perak reported receiving grants from the Woman’s Board of Northwestern Memorial Hospital; the Dixon Family; the American Heart Association; and the National Heart, Lung, and Blood Institute. Dr. Daniels reported no conflicts of interest.

Abrocitinib, an investigational drug proven to be a safe and effective treatment for moderate to severe atopic dermatitis (AD) in adults 18 years and older, is also safe and effective in patients aged 12-17 years, according to a randomized trial of the oral, once-daily Janus kinase (JAK) 1 selective inhibitor, used in combination with medicated topical therapy.

The results, from the phase 3 JADE TEEN study, were presented during an oral abstract session at the annual meeting of the American Academy of Allergy, Asthma, and Immunology, held virtually this year.

“We’re very excited about the introduction of oral JAKs into our armamentarium for atopic dermatitis,” lead author Lawrence Eichenfield, MD, professor of dermatology and pediatrics, University of California, San Diego, and chief of pediatric and adolescent dermatology, Rady Children’s Hospital, also in San Diego, said in an interview.

AD ranges in severity, and there is a great deal of moderate to severe AD that has a tremendous negative impact on the individual, Dr. Eichenfield said. “Traditionally we have treated it with intermittent topical corticosteroids, but this has left a significant percentage of patients without long-term disease control.”

JAK inhibitors are effective mediators of the inflammation response that occurs in moderate to severe AD. They inhibit the stimulation of the JAK pathway and allow anti-inflammatory effects and therefore have potential, especially in more severe disease, Dr. Eichenfield said.

In the current study, which is a spin-off of the original study that looked at abrocitinib in adults, he and his team randomly assigned 285 teens (mean age, 14.9 years; 50.9% male; 56.1% White) with moderate to severe AD to receive one of the following treatments for 12 weeks: abrocitinib 200 mg plus topical therapy (95); abrocitinib 100 mg plus topical therapy (95); or placebo, which consisted of topical therapy alone (95).

The primary endpoints were an Investigator’s Global Assessment response of clear or almost clear (scores of 0 and 1, respectively), with an improvement of at least 2 points, and an improvement in Eczema Area and Severity Index score of at least 75% at week 12.

Secondary endpoints included an improvement in Peak Pruritus Numerical Rating Scale (PP-NRS) response of at least 4 points at week 12.

The teens who received abrocitinib along with medicated topical therapy showed significant improvement in the severity of their AD at the end of the 12-week period, compared with those in the placebo group.

“The percentage of patients achieving essentially no itch, as captured in the fact that more than half of those on the higher dose of abrocitinib made it to no itch, is a new data point and is important to note,” Dr. Eichenfield said. “A lot of the other medicines don’t really get a significant percentage of the population to an itch score of 0 to 1. This drug brought about a rapid and profound itch relief.”

He added: “The results from JADE TEEN extend the drug’s utility in this younger population and show that abrocitinib performs the same with regard to efficacy and safety in the teenagers. Having atopic dermatitis that does not respond to treatment is especially hard for adolescents, but now we know that abrocitinib will be safe and effective and so we now have something to offer these kids.”

“Abrocitinib achieved a good response in this study that was statistically significant, compared to standard treatment,” Jonathan A. Bernstein, MD, professor of medicine at the University of Cincinnati, commented in an interview.

“JAK inhibitors are very promising, and this study adds to that promise. They play an important role in atopic dermatitis, so obviously, teenagers with AD represent an important population,” said Dr. Bernstein, who was not part of the study. “These results are very encouraging, and I think that we will probably see some of these JAK inhibitors approved by the FDA, if not this year, probably next.”

The study was sponsored by Pfizer. Dr. Eichenfield serves as an investigator, speaker, and consultant for Pfizer; and as an investigator, speaker, consultant, and/or is on a data safety monitoring board for AbbVie, Almirall, Amgen, Arcutis, Asana, Dermavant, Dermira, Forte, Galderma, Ichnos/Glenmark, Incyte, LEO, Lilly, L’Oreal, Novartis, Regeneron, Sanofi-Genzyme, and Verrica. Dr. Bernstein disclosed no relevant financial relationships.

EVIDENCE SUMMARY

Metformin has modest effects on body weight

A large systematic review and meta-­analysis (38 RCTs; n = 2199) published in 2020 evaluated metformin therapy in children and adolescents (including those with metabolic disease, growth problems, and psychological disorders in addition to obesity and overweight).¹ Over an average of 6 months, metformin use modestly reduced BMI (weighted mean difference [WMD] = –1.07 kg/m²; 95% CI, –1.43 to –0.72 kg/m²) and body weight (WMD = –2.51 kg; 95% CI, –3.14 to –1.89 kg) for all participants.¹

However, the authors also performed a meta-analysis of trials involving obese or overweight youth without other comorbidities. Participants in these trials ranged in age from 7 to 17 years (mean not supplied; most trials, 12-15 years), had a BMI greater than the 95th percentile for age, and took doses of metformin ranging from 1500 to 3000 mg (most trials, 1500-2000 mg/d for 24 weeks).¹ In this analysis, metformin reduced body weight (8 trials; n = 616; WMD = –2.06 kg; 95% CI, –3.47 to –0.65 kg) and body fat mass (–1.9%; 95% CI, –3.25% to –0.56%). But it did not reduce BMI (12 trials; n = 826; WMD = –0.76 kg/m²; 95 % CI, –1.61 to 0.08 kg/m²) or improve lean body mass (2 trials; N = 98; WMD = –0.74 kg; 95% CI, –2.4 to 0.91 kg).¹

The authors of this meta-analysis did not include an evaluation of the quality of the individual RCTs.

Metformin has benefits but also adverse effects

A 2016 Cochrane systematic review and ­meta-analysis assessed 8 trials (total n = 543) evaluating metformin vs placebo in adolescents prescribed exercise and lifestyle support.² This meta-analysis included 4 trials (n = 294) with obese or overweight adolescents that were also included in the newer meta-analysis,¹ as well as 4 trials involving obese adolescents with insulin resistance. The authors did not assess the effects of metformin on obese or overweight adolescents separately.

Over 6 months, metformin use reduced BMI (WMD = –1.35 kg/m²; 95% CI –2 to –0.69 kg/m²).² Metformin commonly produced gastrointestinal symptoms: diarrhea, flatulence (rates not given), and nausea in 15% to 42% compared with 3% to 21% with placebo (no comparison statistic supplied), however rarely to the point of discontinuation (< 5%).² Nine participants withdrew due to adverse effects: 5 in the metformin group and 4 in the placebo group. The authors rated the quality of the included trials as low to moderate.

An evidence report and systematic review (42 RCTs; total n = 6956) compared the efficacy of several approaches for weight loss in adolescents, including metformin (6 of the 8 RCTs included in the 2020 meta-analysis¹) and lifestyle interventions.³ Interventions comprising exercise and diet counseling for > 26 hours over 6 to 12 months produced decreases in BMI (–0.86 kg/m²; 95% CI –1.44 to –0.29 kg/m²) but not weight (–2 kg; 95% CI –3.2 to 1.2 kg).³

Recommendations from others

The US Preventive Services Task Force states that metformin treatment in adolescents who are overweight or obese produces a small reduction in BMI when compared to placebo, but the clinical significance of this reduction is unclear.³

Editor’s takeaway

The idea of using medications for weight loss remains seductive, given how hard it can be for patients to achieve significant, lasting weight loss through lifestyle modification. Evidence suggests that metformin can help in this regard but not enough to recommend it. In addition, metformin therapy is associated with gastrointestinal adverse effects.

Editor’s takeaway

The idea of using medications for weight loss remains seductive, given how hard it can be for patients to achieve significant, lasting weight loss through lifestyle modification. Evidence suggests that metformin can help in this regard but not enough to recommend it. In addition, metformin therapy is associated with gastrointestinal adverse effects.

EVIDENCE SUMMARY

Metformin has modest effects on body weight

A large systematic review and meta-­analysis (38 RCTs; n = 2199) published in 2020 evaluated metformin therapy in children and adolescents (including those with metabolic disease, growth problems, and psychological disorders in addition to obesity and overweight).¹ Over an average of 6 months, metformin use modestly reduced BMI (weighted mean difference [WMD] = –1.07 kg/m²; 95% CI, –1.43 to –0.72 kg/m²) and body weight (WMD = –2.51 kg; 95% CI, –3.14 to –1.89 kg) for all participants.¹

However, the authors also performed a meta-analysis of trials involving obese or overweight youth without other comorbidities. Participants in these trials ranged in age from 7 to 17 years (mean not supplied; most trials, 12-15 years), had a BMI greater than the 95th percentile for age, and took doses of metformin ranging from 1500 to 3000 mg (most trials, 1500-2000 mg/d for 24 weeks).¹ In this analysis, metformin reduced body weight (8 trials; n = 616; WMD = –2.06 kg; 95% CI, –3.47 to –0.65 kg) and body fat mass (–1.9%; 95% CI, –3.25% to –0.56%). But it did not reduce BMI (12 trials; n = 826; WMD = –0.76 kg/m²; 95 % CI, –1.61 to 0.08 kg/m²) or improve lean body mass (2 trials; N = 98; WMD = –0.74 kg; 95% CI, –2.4 to 0.91 kg).¹

The authors of this meta-analysis did not include an evaluation of the quality of the individual RCTs.

Metformin has benefits but also adverse effects

A 2016 Cochrane systematic review and ­meta-analysis assessed 8 trials (total n = 543) evaluating metformin vs placebo in adolescents prescribed exercise and lifestyle support.² This meta-analysis included 4 trials (n = 294) with obese or overweight adolescents that were also included in the newer meta-analysis,¹ as well as 4 trials involving obese adolescents with insulin resistance. The authors did not assess the effects of metformin on obese or overweight adolescents separately.

Over 6 months, metformin use reduced BMI (WMD = –1.35 kg/m²; 95% CI –2 to –0.69 kg/m²).² Metformin commonly produced gastrointestinal symptoms: diarrhea, flatulence (rates not given), and nausea in 15% to 42% compared with 3% to 21% with placebo (no comparison statistic supplied), however rarely to the point of discontinuation (< 5%).² Nine participants withdrew due to adverse effects: 5 in the metformin group and 4 in the placebo group.

Late one night in early February, Jen Gunter, MD, was scrolling online when she discovered a new “feminine hygiene” product being marketed for teen girls. The new vanilla clementine scented wipes and cleansers with confetti-colored packaging and a cute name (OMV!) irked Dr. Gunter because they are designed for girls to use to “freshen” their vaginal area.

Dr. Gunter, a San Francisco-based gynecologist and author of “The Vagina Bible,” has built a reputation as a fierce advocate for women’s health and debunker of pseudoscience. She has called out jade eggs and “detox pearls” and various other items that promise to improve the vagina but that she and other doctors warn could actually be harmful. And, in her view, this product is no different.

She fired off a tweet that became the first volley in a vociferous social media countercampaign: “Hey @vagisil going to call you out here for this predatory line of products aimed at teen girls. Why do you think teen vulvas need special cleaning? To be prepped for men? Because they are dirty. Anxiously awaiting your answer as are all my followers.”

Vagisil responded on Instagram that “we want to clarify any confusion or the underlying belief that OMV! was developed because there is something wrong with teens or that vulvas/vaginas are inherently dirty. That is not the case. All-Day Fresh Wash is an all-over body wash, that is safe, gentle, and pH-balanced for sensitive vulvar area skin.”

Dr. Gunter’s Feb. 4 tweet attracted more than 8,300 likes, 1,300 retweets and hundreds of comments, but that was just the beginning. Dr. Gunter has continued to tweet about the OMV! product line – and has inspired dozens of other gynecologists to join in.
 

‘Your vagina is fine’

Dr. Gunter and other gynecologists have long delivered the message that water alone is sufficient to cleanse the vulvar area and that the vagina itself is self-cleaning. Research into the vaginal microbiome reveals the role of lactobacilli in preventing urogenital diseases. “Disturbances in your vagina microbiome are hard to undo,” says Jocelyn Fitzgerald, MD, a urogynecologist and pelvic reconstructive surgeon at Magee-Womens Hospital at the University of Pittsburgh Medical Center.

To underscore that message, Dr. Fitzgerald recently tweeted in support of Dr. Gunter’s Twitter thread: “Honestly, the @vagisil marketing campaign is a brilliant one because using their products while your vagina is perfectly fine will destroy your microbiome, give you real Bacterial Vaginosis, and prompt you to buy more Vagisil. DON’T FALL FOR IT GIRLS YOUR VAGINA IS FINE.”

In an emailed response to this news organization, a Vagisil spokesperson said, “We follow industry best practices for testing and OMV! products are rigorously assessed for safety and quality. In addition, we work with respected, independent clinical labs that follow strict testing protocols, using board-certified gynecologists and dermatologists to test our products before launch.”

However, beyond the potential for irritation or misuse, the gynecologists zeroed in on the underlying message that girls would feel more confident if they used the wipes and cleanser. For example, the company suggested that teens could use the wipes to get rid of “period funk.”

“There is no such thing as period funk!” gynecologist Danielle Jones, MD, exclaimed in a video on YouTube, where she has a channel called Mama Doctor Jones – with 700,000 subscribers. “All you need is ordinary hygiene. Period funk is not a thing! And if you feel like something is going on because there’s an odor that is abnormal, you need to talk to your doctor.”

Adult women often use wipes and special cleansers in the vaginal area. An online survey of 1,435 Canadian women, published in BMC Women’s Health in 2018, found 42% had used vaginal wipes, 12% had used vaginal washes or cleansers – and 4% had used them internally.

When it launched OMV! in July, Vagisil said it had engaged 2,500 teens and their mothers in creating the product, which it said was “designed to meet the cleansing and care needs of a new generation of young women.”

That extension of a product most commonly used by adult women to teenagers – who often feel self-conscious about their bodies – is exactly what bothers Dr. Gunter. “BTW I am sorry I am subjecting you all to my @vagisil outrage, but preying on teens and amplifying patriarchal shame of normal bodily functions to sell an irritating product is not acceptable. I’m not stopping until they take that OMV! product line down everywhere,” she said in a Feb. 8 tweet that attracted more than 7,900 likes.
 

No ‘glow up’ needed

Dr. Gunter’s tweets tapped into collective anger over the shaming of women’s bodies. The OMV! marketing suggested that teens could get a “glow up” with the products.

“Your vulva doesn’t need a ‘glow up.’ It’s fine like it is. And if it’s not, talk to your doctor,” Dr. Jones said in her Feb. 8 video, which has had almost 350,000 views, with 28,000 likes and only 149 dislikes.

“They’re very clearly pathologizing normal physiology,” Dr. Jones says. “They’re creating language that makes people feel as though their normal bodily functions have to be somehow fixed or changed.”

Dr. Gunter says she specifically wanted to prevent Vagisil from leveraging social media to influence teen girls. With her stream of tweets and support from colleagues around the country, she has sparked a prolonged online conversation.

“I am encouraged by the strong response on social media from both other enraged ob.gyns. and health care professionals as well the response from a lot of women and men,” Dr. Gunter said in an interview. “We have effectively blocked [Vagisil] from using social media.”

In its response to this news organization, Vagisil noted, “We are a brand run by women with daughters of our own.” While defending the products, Vagisil acknowledged the criticisms: “We are always listening to our consumers and our expert partners so that we continuously evolve. We appreciate the perspective that our language choice surrounding periods may perpetuate an old idea and have already begun to make changes to address this.”

Dr. Gunter says she plans to stay on topic. “Given the number of people outraged, I suspect if they venture out on social media again the reaction will be swift,” she said. “Hopefully we have made OMV! toxic for influencers as well.”

In fact, she’s ready to take on “the entire predatory feminine hygiene market. I’m sick of their false claims about balancing pH and not-so-subtle suggestions that vaginas and vulvas and menstruation stink. These products cause psychological harm as well as physical harm from their irritants,” she said.

THE CASE

A 14-year-old girl with no significant medical history presented to the office accompanied by her mother for a routine well-adolescent visit. She attended school online due to a history of severe bullying and, when interviewed alone, admitted to a lack of a social life as a result. On questioning, she denied tobacco, alcohol, or illicit drug use. Her gender identity was female. Her sexual orientation was toward both males and females, but she was not sexually active. She denied exposure to physical or emotional violence at home and said she did not feel depressed or think about suicide.

Physical examination revealed multiple erythematous linear scars surrounding the areola of both breasts. When questioned about these lesions, she admitted to cutting herself on the breasts during the past several months but again denied suicidal intent. She believed that her behavior was a normal coping mechanism. 

The physical exam was otherwise normal. Lab results, including thyroid-stimulating hormone and complete blood count, were within normal limits.

THE DIAGNOSIS

The physical exam findings and the patient’s self report pointed to a diagnosis of nonsuicidal self-injurious (NSSI) behavior involving cutting.

DISCUSSION

The NSSI behavior displayed by this patient is a common biopsychosocial disorder observed in adolescents. Self-injury is defined as the deliberate injuring of body tissues without suicidal intent.¹ Self-injurious behavior typically begins when patients are 13 to 16 years of age, and cutting is the most common form. Most acts occur on the arms, legs, wrists, and stomach.² Studies have shown that the prevalence of this behavior is on the rise among adolescents, from about 7% in 2014 to between 14% and 24% in 2015.³

Risk for suicide. Although a feature of NSSI is the lack of suicidal intent, this type of high-risk behavior is associated with past, present, and future suicide attempts. It is important for physicians to identify NSSI in an adolescent, as it is linked to a 7-fold increased risk for a suicide attempt.³

Screening for NSSI. Less than one-fifth of adolescents who injure themselves come to the attention of health care providers.⁴ We propose that primary care physicians add NSSI to the list of risky behaviors—including drug abuse, sexual activity, and depression—for which they screen during well-child visits.

Continue to: Identifying risk factors

Identifying risk factors. The case patient experienced bullying and reported a nonheterosexual orientation, both of which have been demonstrated as strong risk factors for NSSI.⁵ Female gender has also been identified as a risk factor for NSSI.³

In adolescent psychiatric samples, prevalence rates of NSSI were found to be as high as 60% for 1 incident of NSSI and around 50% for repetitive NSSI.⁶ NSSI coincides with other psychiatric comorbidities, including eating disorders, mood disorders (depression), anxiety disorders, posttraumatic stress disorder, and borderline personality disorder.³ In a study of 93 subjects, each of whom was a self-reported abuse survivor with a history of self-injury, 96% were in therapy for diagnoses that included posttraumatic stress disorder (73%), dissociative disorder (40%), borderline personality disorder (37%), and multiple personality disorder (29%).⁷

Some patients may self-harm to generate feeling when emotionally empty or to avert suicidal intent.

The experience of adverse childhood events also increases risk for NSSI. This includes parental neglect, abuse, or deprivation.⁶ Insecure paternal attachment and parental neglect are significant predictors for women, while childhood separation is a primary predictor for men.⁸ Indirect childhood maltreatment, such as witnessing domestic violence or increased parental critique, is also associated with NSSI.⁸ NSSI is also more prevalent among young people who identify with a subculture such as gothic or emo.⁶

Why they do it and how to help

In multiple studies aimed at identifying reasons for self-injury, converging evidence suggests that nearly all patients act with the intent of alleviating negative affect.⁹ Patients self-harm to regulate distress, anxiety, and frustration that they perceive to be intolerable.⁹ They may self-harm to generate feeling when emotionally empty or to avert suicidal intent.⁹ For others, self-harm is a way to communicate their distress.

How to proceed. After a physician identifies NSSI, the patient should be assessed for suicidality and medical severity of the injury.³ Factors associated with higher likelihood of suicidality in patients with NSSI include multiple self-injurious methods and locations, early age of onset, longer history of NSSI, recent worsening of the injuries, simultaneous substance use, and the perception that the patient is addicted to self-injury.¹⁰

Continue to: It is also important...

It is also important to ask the patient whether she or he has told anyone about the behavior. Participation in NSSI communities may reinforce it.³

Treatment found to be effective for NSSI involves dialectical behavioral therapy, cognitive behavioral therapy, and mentalization-based therapy.¹¹

Our patient was admitted to the hospital several weeks after her well visit because she expressed suicidal ideation. After being discharged, she was referred to outpatient Psychiatry with a treatment plan that included cognitive behavioral therapy.

THE TAKEAWAY

While our patient may have concealed her self-injurious experience because of stigma and concern about others’ reactions, there were several risk factors for NSSI in her history that prompted further investigation with a skin exam.

If a patient presents with 1 or more risk factors, an initial assessment for possible NSSI should be performed with detailed history-taking and a skin exam. Once NSSI is identified, the initial response and tone of questioning toward the patient need to convey a sense of genuine curiosity about the patient’s experience. From there, the physician can avail the patient to the proper treatment modalities.

NSSI patients can be resistant to sharing and participating in support groups. However, a referred counselor can follow up with a stepwise approach to slowly gain the trust of the individual, find the root cause, and get the patient to a point where she or he is ready to start the necessary treatment.

In adolescent psychiatric samples, prevalence rates of NSSI were found to be as high as 60% for 1 incident of NSSI and around 50% for repetitive NSSI.⁶ NSSI coincides with other psychiatric comorbidities, including eating disorders, mood disorders (depression), anxiety disorders, posttraumatic stress disorder, and borderline personality disorder.³ In a study of 93 subjects, each of whom was a self-reported abuse survivor with a history of self-injury, 96% were in therapy for diagnoses that included posttraumatic stress disorder (73%), dissociative disorder (40%), borderline personality disorder (37%), and multiple personality disorder (29%).⁷

Some patients may self-harm to generate feeling when emotionally empty or to avert suicidal intent.

The experience of adverse childhood events also increases risk for NSSI. This includes parental neglect, abuse, or deprivation.⁶ Insecure paternal attachment and parental neglect are significant predictors for women, while childhood separation is a primary predictor for men.⁸ Indirect childhood maltreatment, such as witnessing domestic violence or increased parental critique, is also associated with NSSI.⁸ NSSI is also more prevalent among young people who identify with a subculture such as gothic or emo.⁶

Why they do it and how to help

In multiple studies aimed at identifying reasons for self-injury, converging evidence suggests that nearly all patients act with the intent of alleviating negative affect.⁹ Patients self-harm to regulate distress, anxiety, and frustration that they perceive to be intolerable.⁹ They may self-harm to generate feeling when emotionally empty or to avert suicidal intent.⁹ For others, self-harm is a way to communicate their distress.

How to proceed. After a physician identifies NSSI, the patient should be assessed for suicidality and medical severity of the injury.³ Factors associated with higher likelihood of suicidality in patients with NSSI include multiple self-injurious methods and locations, early age of onset, longer history of NSSI, recent worsening of the injuries, simultaneous substance use, and the perception that the patient is addicted to self-injury.¹⁰

It is also important to ask the patient whether she or he has told anyone about the behavior. Participation in NSSI communities may reinforce it.³

Treatment found to be effective for NSSI involves dialectical behavioral therapy, cognitive behavioral therapy, and mentalization-based therapy.¹¹

Our patient was admitted to the hospital several weeks after her well visit because she expressed suicidal ideation. After being discharged, she was referred to outpatient Psychiatry with a treatment plan that included cognitive behavioral therapy.

THE TAKEAWAY

While our patient may have concealed her self-injurious experience because of stigma and concern about others’ reactions, there were several risk factors for NSSI in her history that prompted further investigation with a skin exam.

If a patient presents with 1 or more risk factors, an initial assessment for possible NSSI should be performed with detailed history-taking and a skin exam. Once NSSI is identified, the initial response and tone of questioning toward the patient need to convey a sense of genuine curiosity about the patient’s experience. From there, the physician can avail the patient to the proper treatment modalities.

NSSI patients can be resistant to sharing and participating in support groups. However, a referred counselor can follow up with a stepwise approach to slowly gain the trust of the individual, find the root cause, and get the patient to a point where she or he is ready to start the necessary treatment.

THE CASE

A 14-year-old girl with no significant medical history presented to the office accompanied by her mother for a routine well-adolescent visit. She attended school online due to a history of severe bullying and, when interviewed alone, admitted to a lack of a social life as a result. On questioning, she denied tobacco, alcohol, or illicit drug use. Her gender identity was female. Her sexual orientation was toward both males and females, but she was not sexually active. She denied exposure to physical or emotional violence at home and said she did not feel depressed or think about suicide.

Physical examination revealed multiple erythematous linear scars surrounding the areola of both breasts. When questioned about these lesions, she admitted to cutting herself on the breasts during the past several months but again denied suicidal intent. She believed that her behavior was a normal coping mechanism. 

The physical exam was otherwise normal. Lab results, including thyroid-stimulating hormone and complete blood count, were within normal limits.

THE DIAGNOSIS

The physical exam findings and the patient’s self report pointed to a diagnosis of nonsuicidal self-injurious (NSSI) behavior involving cutting.

DISCUSSION

The NSSI behavior displayed by this patient is a common biopsychosocial disorder observed in adolescents. Self-injury is defined as the deliberate injuring of body tissues without suicidal intent.¹ Self-injurious behavior typically begins when patients are 13 to 16 years of age, and cutting is the most common form. Most acts occur on the arms, legs, wrists, and stomach.² Studies have shown that the prevalence of this behavior is on the rise among adolescents, from about 7% in 2014 to between 14% and 24% in 2015.³

Risk for suicide. Although a feature of NSSI is the lack of suicidal intent, this type of high-risk behavior is associated with past, present, and future suicide attempts. It is important for physicians to identify NSSI in an adolescent, as it is linked to a 7-fold increased risk for a suicide attempt.³

Screening for NSSI. Less than one-fifth of adolescents who injure themselves come to the attention of health care providers.⁴ We propose that primary care physicians add NSSI to the list of risky behaviors—including drug abuse, sexual activity, and depression—for which they screen during well-child visits.

Although the only pediatric indication for chimeric antigen receptor T-cell therapy currently approved by the Food and Drug Administration is B-lineage acute lymphoblastic leukemia (ALL) that is refractory to at least two frontline induction attempts or is in second or later relapse, clinical trials of CAR-T therapy for pediatric solid tumors are also currently in progress, said Gregory Yanik, MD, from the CS Mott Children’s Hospital at the University of Michigan, Ann Arbor, at the Transplant & Cellular Therapies Meetings.

In his presentation, Dr. Yanik discussed progress in solid tumor studies as well as some issues involving the current use of CAR-T therapy for ALL.

Solid tumor studies

Malignancies such as sarcomas, brain tumors, and neuroblastomas pose unique challenges, “In contrast to hematologic malignancies, the protein we’re targeting may not be present on the cell surface of all the tumor cells. There are lower-expression profiles, and this is a problem. In fact, many people have postulated that with CAR-T for pediatric solid tumors we’ll have to do repeated cycles, almost like we do with chemotherapy,” he said at the meeting held by the American Society for Blood and Marrow Transplantation and the Center for International Blood and Marrow Transplant Research.

There are currently 14 studies of CAR-T for central nervous system tumors in children, targeting either epidermal growth factor receptor (EGFR) in glioblastoma multiforme and high-grade gliomas, HER2 in a variety of CNS tumors, the GD2 antigen on pontine gliomas, and the checkpoint molecular B7H3 in medulloblastomas and pontine gliomas.

“In sarcomas in kids there are currently 12 trials in progress. Most of the targeting epitopes are targeting either HER2 or GD2. Repetitive CAR-T infusions are being used in several of these trials in sarcomas.

For neuroblastomas there are currently 13 studies in progress, nearly all of which target GD2. Some of the trials include combining CAR-T with immune checkpoint inhibitors or C7R, an engineered cytokine driver designed to prevent T-cell exhaustion.

In addition, several trials of tumor pulsed dendritic cell vaccines are underway for treatment of children with Wilms tumor, Dr. Yanik noted.
 

Unresolved procedural questions

It’s still early days in CAR-T therapy, and there are several still unanswered questions regarding optimal therapy for and management of patients undergoing CAR-T procedures, Dr. Yanik said.

For example, the optimal time to collect T cells during apheresis is still unclear, he said. Collecting prior to reinduction therapy raises the risk of transducing leukemic cells, while collecting after reinduction may result in inadequate quantity or quality of cells. Regardless of when cells are collected, apheresis should be performed only when the absolute lymphocyte count is above 500/mcL or the CD3 count is above 150/mcL at the time of apheresis.

In the case tisagenlecleucel (Kymriah), his center typically collects 1x10⁹ CD3 cells regardless of age or weight.

The number of CAR T-cells infused also appears to matter, as responses are improved at CAR-T doses above 1.5x10⁶/kg, while risk for higher-grade cytokine release syndrome (CRS) occurs at higher infusion doses.
 

Blinatumomab or inotuzumab?

Along with CAR-T, two other agents, the bispecific T-cell engager blinatumomab (Blincyto) and the antibody conjugate inotuzumab ozogamicin (Besponsa) are also approved for the treatment of patients with relapsed/refractory B-cell ALL.

Like CAR-T therapy, the primary toxicities associated with blinatumomab are CRS and neurologic adverse events, whereas at inotuzumab is largely associated with hematologic and hepatic toxicities.

The logistics of therapy differ widely, with a 28-day infusion required for blinatumomab, compared with weekly dosing of inotuzumab, and the multiple visits for apheresis and infusion required for CAR-T.

Blinatumomab is approved for both children and adults with relapsed/refractory ALL, but inotuzumab is approved only for adults, and CAR-T with tisagenlecleucel is approved only for children in this indication.
 

CD-19 expression

There is evidence to suggest that CD19 expression prior to CAR-T has an effect on outcomes, Dr. Yanik said.

“Does blinatumomab pre–CAR-T impact outcome? The answer is probably yes,” he said.

He referred to a study by investigators at the Children’s Hospital of Philadelphia showing that, “if you’re giving blinatumomab prior to CAR-T therapy, you’re potentially reducing the cell-surface expression of CD19 on your leukemic blasts, and now while you’re bringing these patients in for CAR-T therapy, you’re getting a much higher population of dim CD19 expressers, and this is associated with a higher relapse rate and lower remission rate.”
 

Predicting relapse

Dr. Yanik referred to a study, currently unpublished, which will show that next-generation sequencing (NGS) is more sensitive than flow cytometry for detection of minimal residual disease (MRD), and that MRD analysis of marrow was more sensitive than analysis of peripheral blood.

“Poor outcomes were seen post CAR-T for patients who were in morphologic remission on day 28 or day 100, but had positive MRD. This especially held true if it was next-gen sequencing MRD-positive at day 100, for which relapse rates were over 95%,” he said.

The absence of B-cells is a surrogate marker for the persistence of CAR-T, and conversely, the recovery of CD19-positive B cells may be a predictor for relapse, especially if the B-cell recovery occurs within the first 6 months following CAR-T infusion.
 

Transplant after CAR-T?

Bone marrow transplant after CAR-T is recommend for patients with high risk of relapse, including those with B-cell recovery within the first 6 months after CAR-T, patients with MRD positivity at days 28 or 100, and patients with mixed lineage leukemia.

“Should we transplant good-risk patients, meaning, if you have NGS-MRD negative patients, is there a role for transplant? You have to look at the risk versus benefit there. These patients may have a cure rate that’s in the 80%-plus range, could we potentially optimize that even more if we consolidate them with an allo[geneic] transplant,” Dr. Yank said.
 

Move CAR-T up front?

A Children’s Oncology Group study is currently examining whether giving CAR-T therapy to patients with MRD of 0.01% or greater following first consolidation could result in lower tumor burden, fewer relapse, and less CRS with CAR-T.

Dr. Yanik reported that he had no conflicts of interest to disclose.

Although the only pediatric indication for chimeric antigen receptor T-cell therapy currently approved by the Food and Drug Administration is B-lineage acute lymphoblastic leukemia (ALL) that is refractory to at least two frontline induction attempts or is in second or later relapse, clinical trials of CAR-T therapy for pediatric solid tumors are also currently in progress, said Gregory Yanik, MD, from the CS Mott Children’s Hospital at the University of Michigan, Ann Arbor, at the Transplant & Cellular Therapies Meetings.

Several maternal chronic conditions increase the risk of giving birth to a child with cerebral palsy, based on data from more than 1.3 million Norwegian children.

Mothers with autoimmune disorders, such as diabetes and lupus, had the greatest risks, reported lead author Marianne S. Strøm, MD, of the University of Bergen (Norway) and colleagues.

“The etiologies of cerebral palsy are complex, and only a few prenatal risk factors have been identified,” the investigators wrote in Pediatrics. “Among these possible risk factors are maternal chronic conditions, although studies are typically underpowered and limited to one or two conditions.”

According to Dr. Strøm and colleagues, several components of maternal chronic conditions have been linked with cerebral palsy, including placental abnormalities, altered thrombotic state, and inflammation. Furthermore, mothers with chronic conditions are more likely to give birth prematurely and have children with congenital malformations, both of which have also been associated with cerebral palsy.

To date, however, “there has been no systematic description of maternal chronic conditions and risk of cerebral palsy in offspring,” the investigators noted.

The present, prospective cohort study aimed to meet this need with a population of 1,360,149 children born in Norway from 1990 to 2012, among whom 3,575 had cerebral palsy. Case data were extracted from the Norwegian Patient Registry and the National Insurance Scheme. Information about maternal chronic conditions was extracted from the Medical Birth Registry of Norway and the Norwegian Patient Registry, with the latter also providing information about paternal chronic conditions.

Using log binomial regression models, the investigators determined relative risks of having children with cerebral palsy among parents with chronic conditions versus parents from the general population. This revealed that chronic conditions in fathers had no correlation with cerebral palsy. In contrast, mothers with chronic conditions had a 30% increased risk (relative risk, 1.3; 95% confidence interval, 1.2-1.5), which could be further stratified by number of chronic conditions; mothers with one chronic condition, for instance, had a 20% increased risk (RR, 1.2; 95% CI, 1.1-1.4), while those with two chronic conditions had a 60% increased risk (RR, 1.6; 95% CI, 1.1-2.2), and those with more than two chronic conditions had triple the risk (RR, 3.1; 95% CI, 1.4-6.8)

“The lack of associations between the father’s chronic illness and cerebral palsy risk supports the interpretation that cerebral palsy risk in offspring is the direct result of the mother’s condition and not genetic predisposition or unmeasured situational factors,” the investigators wrote.

Maternal autoimmune conditions were particularly relevant, as they were associated with a 40% increased risk of cerebral palsy (RR, 1.4; 95% CI, 1.1-1.7), a rate that climbed dramatically, to 270%, among mothers with more than one autoimmune condition (RR, 2.7; 95% CI, 1.1-6.6).

“The role of autoimmune diseases in cerebral palsy risk (and maternal inflammation specifically) deserves closer attention,” the investigators wrote. “Using studies with larger sample sizes and a more clinical focus, including measures of placental structure and perinatal blood assays, researchers may be able to explore these possible connections between maternal autoimmune diseases and fetal neurodevelopment.”

Specifically, cerebral palsy in offspring was most strongly associated with maternal Crohn’s disease (RR, 2.1; 95% CI, 1.0-4.1), type 1 diabetes (RR, 2.2; 95% CI, 1.4-3.4), lupus erythematosus (RR, 2.7; 95% CI, 0.9-8.3), and type 2 diabetes (RR, 3.2; 95% CI, 1.8-5.4). Associations were also found for migraine (RR, 1.6; 95% CI, 1.2-2.2), multiple sclerosis (RR, 1.8; 95% CI, 0.8-4.4), and rheumatoid arthritis (RR, 2.0; 95% CI, 1.3-2.9). Several “weaker and less convincing associations” were detected for ulcerative colitis, thyroid disorder, epilepsy, asthma, anemia, and hypertension. Adjusting for parental education level, age, smoking status, and single-mother status did not significantly alter findings. Poisson and logistic regression models generated similar results.

In an accompanying editorial, Sandra Julsen Hollung, PhD, of the Cerebral Palsy Registry of Norway, Vestfold Hospital Trust, Tønsberg, and colleagues, advised that clinicians maintain perspective when discussing these findings with the general public.

“As the authors state, the absolute risk of cerebral palsy associated with at least one chronic maternal condition is low,” wrote Dr. Hollung and colleagues. “Among 1,000 pregnant women with any chronic and/or autoimmune disorder, more than 990 will deliver an infant who will not be diagnosed with cerebral palsy.”

They went on to emphasize that the study findings should not be viewed as firm evidence of causal relationships.

“Thus, the study cannot give clues to any specific preventive treatment,” wrote Dr. Hollung and colleagues. “However, if these disorders are part of a causal pathway, optimal treatment might reduce the risk of cerebral palsy.”

Although Dr. Hollung and colleagues advised that such efforts “would hardly affect the birth prevalence of cerebral palsy,” they also cited the Royal College of Obstetricians and Gynaecologists in the United Kingdom, noting that “each baby counts.”

Emeritus Professor Alastair MacLennan, AO, MB ChB, FRCOG, FRANZCOG, head of the Australian Collaborative Cerebral Palsy Research Group at the University of Adelaide (Australia) suggested that the findings may guide future research.

“An increasing proportion of cerebral palsy cases are being diagnosed by genome sequencing and other genetic techniques to have causative genetic variations,” Dr. MacLennan said. “The possibility of epigenetic interactions are also likely and are still to be investigated. Maternal disorders such as diabetes, lupus, or Crohn’s disease are possible epigenetic factors and this study helps to target these in future genetic and environmental studies of cerebral palsy causation. The days of attributing cerebral palsy to ‘birth asphyxia’ are over.”

The study was supported by the National Institutes of Health and the Western Norwegian Regional Health Authorities. The investigators reported no conflicts of interest.

Several maternal chronic conditions increase the risk of giving birth to a child with cerebral palsy, based on data from more than 1.3 million Norwegian children.

Mothers with autoimmune disorders, such as diabetes and lupus, had the greatest risks, reported lead author Marianne S. Strøm, MD, of the University of Bergen (Norway) and colleagues.

“The etiologies of cerebral palsy are complex, and only a few prenatal risk factors have been identified,” the investigators wrote in Pediatrics. “Among these possible risk factors are maternal chronic conditions, although studies are typically underpowered and limited to one or two conditions.”

According to Dr. Strøm and colleagues, several components of maternal chronic conditions have been linked with cerebral palsy, including placental abnormalities, altered thrombotic state, and inflammation. Furthermore, mothers with chronic conditions are more likely to give birth prematurely and have children with congenital malformations, both of which have also been associated with cerebral palsy.

To date, however, “there has been no systematic description of maternal chronic conditions and risk of cerebral palsy in offspring,” the investigators noted.

The present, prospective cohort study aimed to meet this need with a population of 1,360,149 children born in Norway from 1990 to 2012, among whom 3,575 had cerebral palsy. Case data were extracted from the Norwegian Patient Registry and the National Insurance Scheme. Information about maternal chronic conditions was extracted from the Medical Birth Registry of Norway and the Norwegian Patient Registry, with the latter also providing information about paternal chronic conditions.

Using log binomial regression models, the investigators determined relative risks of having children with cerebral palsy among parents with chronic conditions versus parents from the general population. This revealed that chronic conditions in fathers had no correlation with cerebral palsy. In contrast, mothers with chronic conditions had a 30% increased risk (relative risk, 1.3; 95% confidence interval, 1.2-1.5), which could be further stratified by number of chronic conditions; mothers with one chronic condition, for instance, had a 20% increased risk (RR, 1.2; 95% CI, 1.1-1.4), while those with two chronic conditions had a 60% increased risk (RR, 1.6; 95% CI, 1.1-2.2), and those with more than two chronic conditions had triple the risk (RR, 3.1; 95% CI, 1.4-6.8)

“The lack of associations between the father’s chronic illness and cerebral palsy risk supports the interpretation that cerebral palsy risk in offspring is the direct result of the mother’s condition and not genetic predisposition or unmeasured situational factors,” the investigators wrote.

Maternal autoimmune conditions were particularly relevant, as they were associated with a 40% increased risk of cerebral palsy (RR, 1.4; 95% CI, 1.1-1.7), a rate that climbed dramatically, to 270%, among mothers with more than one autoimmune condition (RR, 2.7; 95% CI, 1.1-6.6).

“The role of autoimmune diseases in cerebral palsy risk (and maternal inflammation specifically) deserves closer attention,” the investigators wrote. “Using studies with larger sample sizes and a more clinical focus, including measures of placental structure and perinatal blood assays, researchers may be able to explore these possible connections between maternal autoimmune diseases and fetal neurodevelopment.”

Specifically, cerebral palsy in offspring was most strongly associated with maternal Crohn’s disease (RR, 2.1; 95% CI, 1.0-4.1), type 1 diabetes (RR, 2.2; 95% CI, 1.4-3.4), lupus erythematosus (RR, 2.7; 95% CI, 0.9-8.3), and type 2 diabetes (RR, 3.2; 95% CI, 1.8-5.4). Associations were also found for migraine (RR, 1.6; 95% CI, 1.2-2.2), multiple sclerosis (RR, 1.8; 95% CI, 0.8-4.4), and rheumatoid arthritis (RR, 2.0; 95% CI, 1.3-2.9). Several “weaker and less convincing associations” were detected for ulcerative colitis, thyroid disorder, epilepsy, asthma, anemia, and hypertension. Adjusting for parental education level, age, smoking status, and single-mother status did not significantly alter findings. Poisson and logistic regression models generated similar results.

In an accompanying editorial, Sandra Julsen Hollung, PhD, of the Cerebral Palsy Registry of Norway, Vestfold Hospital Trust, Tønsberg, and colleagues, advised that clinicians maintain perspective when discussing these findings with the general public.

“As the authors state, the absolute risk of cerebral palsy associated with at least one chronic maternal condition is low,” wrote Dr. Hollung and colleagues. “Among 1,000 pregnant women with any chronic and/or autoimmune disorder, more than 990 will deliver an infant who will not be diagnosed with cerebral palsy.”

They went on to emphasize that the study findings should not be viewed as firm evidence of causal relationships.

“Thus, the study cannot give clues to any specific preventive treatment,” wrote Dr. Hollung and colleagues. “However, if these disorders are part of a causal pathway, optimal treatment might reduce the risk of cerebral palsy.”

Although Dr. Hollung and colleagues advised that such efforts “would hardly affect the birth prevalence of cerebral palsy,” they also cited the Royal College of Obstetricians and Gynaecologists in the United Kingdom, noting that “each baby counts.”

In his role as head of the division of pediatric behavioral health at National Jewish Health, Denver, Bruce G. Bender, PhD, helps children and adults navigate the adverse effects of severe atopic dermatitis (AD) on their quality of life.

“There have been many surveys of adults with AD who report impairment of their sleep, reduced activity level, increased work absence, financial burden, emotional distress, and social avoidance,” he said at the Revolutionizing Atopic Dermatitis virtual symposium. “Similarly, children with AD or their parents report emotional distress, reduced activity, and increased school absence, social avoidance, and sleep disturbance. Families report financial burdens, conflict, particularly among the adults, social avoidance, sleep disturbance in the parents, and reduction of well-being in the siblings.”

Getting adequate sleep is especially challenging for patients with AD, and loss of sleep can have serious daytime consequences. In an effort to objectively measure sleep change in this population, Dr. Bender and colleagues recruited 14 adults with AD and 14 healthy controls who wore an ActiGraph for 1 week and completed questionnaires about sleep, itch, and quality of life. Patients with AD were awake almost twice as many minutes each night as the healthy controls (a mean of 57.3 vs. 32.3 minutes, respectively; P = .0480). Consequently, their sleep efficiency was significantly reduced based on the Pittsburgh sleep quality index (a mean of 90.6 vs. 95; P = .0305).

In another study, Dr. Bender and colleagues enrolled 20 adults with AD who underwent 2 nights of polysomnography and actigraphy. The lab was set up to measure a scratching event, which was recorded when a burst of electromyographic activity of at least 3 seconds was accompanied by a visible scratching motion. “We learned that sleep efficiency as measured by both PSG and actigraphy correlated with total body surface area and scratching index,” he said. “As we might assume, the more skin involved, the more patients scratch, the less well they sleep.”
 

Behavioral, neurocognitive effects

In a separate study of AD, sleep, and behavior, the researchers studied 1,041 children with asthma who were enrolled in the Childhood Asthma Management Program at eight North American sites. They used baseline parent ratings on standardized sleep and behavior rating scales and found that increased awakenings were associated with increased school absence and daytime behavior problems. “So, not only do children with AD sleep less well, but this shows up to impair their functioning during the day,” said Dr. Bender, professor of psychiatry at the University of Colorado, Denver.

In a report from Australia, researchers set out to explore the association between sleep and neurocognitive function in 21 children with eczema and 20 healthy controls. Participants underwent cognitive testing and polysomnography. The authors found that the children with eczema demonstrated lower test scores. Reduced scores were correlated with parental reports of sleep problems but not polysomnography.

In a much larger study funded by the Agency for Healthcare Research and Quality, investigators analyzed data on 354,416 children and 34,613 adults from 19 U.S. population surveys including the National Health Interview Survey 1997-2013 and the National Survey of Children’s Health 2003/4 and 2007/8. They found that AD was associated with ADHD in children (adjusted odds ratio, 1.14) and adults (aOR, 1.61). Higher odds of ADHD were found in children who had significant sleep disturbance (aOR, 16.83) and other allergic disease and asthma (aOR, 1.61).

“All of these findings show that AD can impact quality of life, especially sleep, with the result of poorer daytime functioning,” Dr. Bender said. “But those studies don’t answer this question: Are patients with AD at increased risk for psychological disorders such as depression and anxiety?”
 

Impact on depression, anxiety

Two systematic reviews on the topic suggest that patients with AD are twice as likely to experience depression. One was published in 2018 and the other in 2019. The 2018 review reported a little more than a twofold increase (OR, 2.19), the 2019 review a little bit less (OR, 1.71).

“At the more severe end of the depression continuum, we sometimes see suicidal ideation and suicide attempts,” Dr. Bender said. “A number of studies have asked whether these are increased in patients with AD. Quite a few studies collectively show an increased incidence of suicidal ideation. The question of suicide attempts is reflected in fewer studies. And while the result is small, it is significant. There is a significant increase reported of suicide attempts in AD patients.”

The 2018 review also found an increased incidence of anxiety in AD patients: a little more than twofold in adults (OR, 2.19) and a little less than twofold in children (OR, 1.81).

“It’s a two-way relationship between AD and psychological factors,” Dr. Bender said. “We generally think about AD – the stress that it brings, the burden that it puts on children, adults, and families. But it can work the other way around,” he said, referring to patients who have psychological problems, experience a great deal of stress, have trouble being adherent to their treatment regimen, and find it difficult to resist scratching. “The behavioral/psychological characteristics of the patient also drive the AD. It is well established that acute and chronic stress can result in a worsening of skin conditions in AD patients.”

Behavioral health interventions that have been described in the literature include cognitive therapy, stress management, biofeedback, hypnotherapy, relaxation training, mindfulness, habit reversal, and patient education – some of which have been tested in randomized trials. “All of them report a decrease in scratching as a consequence of the behavioral intervention,” Dr. Bender said.

“Other studies have been reported that look at the impact of behavioral interventions on the severity of the skin condition. Most report an improvement in the skin condition from these behavioral interventions but it’s not a perfect literature.” Critiques of these studies include the fact that there is often not enough detail about the intervention or the framework for the intervention that would allow a clinician to test an intervention in another study or actually pull that intervention into clinical practice (Cochrane Database Syst Rev. 2014 Jan 7;2014[1]:CD004054), (Int Arch Allergy Immunol.2007;144[1]:1-9).

“Some of the studies lack rigorous designs, some have sampling bias, and some have inadequate outcome measurements,” he said. “We really need additional, high-quality studies to look at what is helpful for patients with AD.”

Dr. Bender reported having no financial disclosures.

Metformin has a modest favorable effect on body mass index z score and insulin resistance in children and adolescents with obesity, compared with placebo, according to a systematic review of trial data.

“The available evidence is of varying quality,” however, and the drug increases the likelihood of gastrointestinal adverse effects, reported Reem Masarwa, PharmD, PhD, and colleagues in Pediatrics. “Nonetheless, metformin may be considered for use as a pharmacologic therapy in this pediatric population because of its modest efficacy, availability, cost, and safety profile.”

The Food and Drug Administration has approved metformin for the treatment of type 2 diabetes in children and adolescents. Doctors have used the drug off label for weight loss in children with obesity, but this use “remains controversial,” the review authors said.

To assess the efficacy and safety of metformin plus lifestyle interventions compared with placebo plus lifestyle interventions in children and adolescents with obesity, Dr. Masarwa, with the Center for Clinical Epidemiology, Lady Davis Institute, Jewish General Hospital, and the department of epidemiology, biostatistics, and occupational health, McGill University, Montreal, and colleagues systematically reviewed data from randomized controlled trials (RCTs). Their review was published online in Pediatrics.

The investigators focused on studies that examined outcomes such as body mass index, BMI z score, insulin resistance, and gastrointestinal adverse effects. They excluded studies of children with type 2 diabetes.

The researchers included 24 RCTs in their review. The studies included 1,623 children and adolescents who received metformin (861 participants) or placebo (762 participants). Indications included uncomplicated obesity in 10 studies, obesity with insulin resistance in 9 studies, prediabetes in 3 studies, and nonalcoholic fatty liver disease in 2 studies. One of the trials did not incorporate a lifestyle cointervention.

Participants ranged in age from 4 years to 19 years, and trial durations ranged from 2 months to 2 years. The total daily dose of metformin ranged from 500 mg to 2,000 mg.

In 14 RCTs that reported BMI, metformin generally decreased BMI (range of mean changes: –2.70 to 1.30), compared with placebo (range of mean changes: –1.12 to 1.90), although three trials suggested that metformin increased BMI. The average difference in the treatment effect between the metformin and placebo groups ranged from –2.72 to 0.70. “Importantly, the authors of many RCTs reported variable treatment effects, preventing definitive conclusions from being drawn from individual trials,” Dr. Masarwa and coauthors wrote.

In seven RCTs that reported BMI z score, metformin consistently decreased BMI z score (range of mean changes: –0.37 to –0.03), compared with placebo (range of mean changes: –0.22 to 0.15). The mean difference in the treatment effect between treatment groups ranged from –0.15 to –0.07. The largest decrease occurred in patients with nonalcoholic fatty liver disease.

The rate of gastrointestinal adverse events nearly doubled with metformin treatment, relative to placebo (rate range: 2%-74% for metformin vs. 0%-42% for placebo).

Metformin adherence rates ranged from 60% to 90%, and lifestyle cointerventions varied substantially across the trials, the researchers noted. The clinical significance and long-term effects of metformin treatment in this population “remain uncertain,” they said.
 

Off-label use may not be ideal

“Ideally, children with obesity should be entered into a clinical trial rather than placed on an off-label medication,” Vandana Raman, MD, and Carol M. Foster, MD, said in a related commentary. Still, treatment with metformin may be reasonable in certain cases, said Dr. Raman and Dr. Foster of the division of endocrinology in the department of pediatrics at the University of Utah in Salt Lake City. “Metformin is a low-cost option and may provide modest clinical benefit for weight loss with minimal side effects. If lifestyle modification has been pursued but has achieved minimal weight loss, it may be reasonable to try an agent such as metformin as adjunctive therapy,” they said.

Lifestyle modification therapy – including nutritional changes, physical activity, and behavior modification – has been the “mainstay of management” for patients with obesity, and this approach underpins successful weight loss, they said. But durable weight loss with lifestyle modification may be challenging, and pharmacologic treatments “are attractive options before proceeding to bariatric surgery,” they said.

For younger patients, FDA-approved medications for obesity include orlistat and liraglutide for patients aged 12 years and older, and phentermine for patients aged 16 years and older.

“Orlistat has been associated with modest BMI reduction but may cause intolerable gastrointestinal side effects and possible fat-soluble vitamin deficiency,” they said. “Phentermine is approved for short-term therapy only and may increase heart rate and blood pressure and cause irritability and insomnia.”

Liraglutide, which was approved for the treatment of pediatric obesity in December 2020, reduced BMI in a trial that included adolescents with obesity. About 43% of the participants who received liraglutide, compared with 18% who received placebo, had a 5% reduction in BMI. In addition, 26% and 8%, respectively, had a 10% reduction in BMI. The use of liraglutide “is limited by the need for daily subcutaneous injections and high frequency of gastrointestinal side effects and high cost,” however, the commentary authors noted.

In addition, the FDA has approved setmelanotide for children older than 6 years with obesity caused by three rare genetic conditions.

Some small studies have suggested that topiramate may lead to meaningful weight loss in children, but the medication has been associated with cognitive dysfunction, they said.
 

Considering surgery

“This is an important review of the efficacy of metformin as a tool for weight loss in children with obesity,” said Suzanne C. Boulter, MD, adjunct professor emeritus of pediatrics and community and family medicine at the Geisel School of Medicine at Dartmouth in Hanover, N.H. “Results showed modest decreases in BMI z scores compared to placebo but there were a significant percentage of GI side effects and dropouts from the trials.”

“Tools other than lifestyle changes are needed to address” pediatric obesity, Dr. Boulter said. “Another tool is gastric bypass which is now a recommended intervention in selected clinical sites for adolescents 14 years of age and older with BMIs greater than 35.”

Dr. Boulter highlighted a recent study in Pediatrics that examined data from more than 200 adolescents who underwent bariatric surgery. The researchers found that outcomes were similar for older and younger patients.

“It would be interesting to pediatricians in practice to see a comparison study between metformin and bariatric surgery long-term results,” Dr. Boulter added.

Metformin has a modest favorable effect on body mass index z score and insulin resistance in children and adolescents with obesity, compared with placebo, according to a systematic review of trial data.

“The available evidence is of varying quality,” however, and the drug increases the likelihood of gastrointestinal adverse effects, reported Reem Masarwa, PharmD, PhD, and colleagues in Pediatrics. “Nonetheless, metformin may be considered for use as a pharmacologic therapy in this pediatric population because of its modest efficacy, availability, cost, and safety profile.”

The Food and Drug Administration has approved metformin for the treatment of type 2 diabetes in children and adolescents. Doctors have used the drug off label for weight loss in children with obesity, but this use “remains controversial,” the review authors said.

To assess the efficacy and safety of metformin plus lifestyle interventions compared with placebo plus lifestyle interventions in children and adolescents with obesity, Dr. Masarwa, with the Center for Clinical Epidemiology, Lady Davis Institute, Jewish General Hospital, and the department of epidemiology, biostatistics, and occupational health, McGill University, Montreal, and colleagues systematically reviewed data from randomized controlled trials (RCTs). Their review was published online in Pediatrics.

The investigators focused on studies that examined outcomes such as body mass index, BMI z score, insulin resistance, and gastrointestinal adverse effects. They excluded studies of children with type 2 diabetes.

The researchers included 24 RCTs in their review. The studies included 1,623 children and adolescents who received metformin (861 participants) or placebo (762 participants). Indications included uncomplicated obesity in 10 studies, obesity with insulin resistance in 9 studies, prediabetes in 3 studies, and nonalcoholic fatty liver disease in 2 studies. One of the trials did not incorporate a lifestyle cointervention.

Participants ranged in age from 4 years to 19 years, and trial durations ranged from 2 months to 2 years. The total daily dose of metformin ranged from 500 mg to 2,000 mg.

In 14 RCTs that reported BMI, metformin generally decreased BMI (range of mean changes: –2.70 to 1.30), compared with placebo (range of mean changes: –1.12 to 1.90), although three trials suggested that metformin increased BMI.

The number of new COVID-19 cases in children declined for the sixth consecutive week, but the drop was the smallest yet, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

New child cases in the United States totaled 64,264 for the week of Feb. 19-25, down from 70,640 the week before. That drop of almost 6,400 cases, or 9.0%, falls short of the declines recorded in any the previous 5 weeks, which ranged from 18,000 to 46,000 cases and 15.3% to 28.7%, based on data from the heath departments of 49 states (excluding New York), as well as the District of Columbia, New York City, Puerto Rico, and Guam.

The total number of children infected with SARS-CoV-2 is up to almost 3.17 million, which represents 13.1% of cases among all age groups. That cumulative proportion was unchanged from the previous week, which has occurred only three other times over the course of the pandemic, the AAP and CHA said in their weekly COVID-19 report.

Despite the 6-week decline in new cases, however, the cumulative rate continued to climb, rising from 4,124 cases per 100,000 children to 4,209 for the week of Feb. 19-25. The states, not surprisingly, fall on both sides of that national tally. The lowest rates can be found in Hawaii (1,040 per 100,000 children), Vermont (2,111 per 100,000), and Maine (2,394), while the highest rates were recorded in North Dakota (8,580), Tennessee (7,851), and Rhode Island (7,223), the AAP and CHA said.

The number of new child deaths, nine, stayed in single digits for a second consecutive week, although it was up from six deaths reported a week earlier. Total COVID-19–related deaths in children now number 256, which represents just 0.06% of coronavirus deaths for all ages among the 43 states (along with New York City and Guam) reporting such data.

Among those jurisdictions, Texas (40), Arizona (27), and New York City (23) have reported the most deaths in children, while nine states and the District of Columbia have reported no deaths yet, the AAP and CHA noted.
