Study: Physical fitness in children linked with concentration, quality of life

Article Type
Changed

Physically fit children have a greater ability to concentrate and better health-related quality of life (HRQOL), according to a new study.

The findings of the German study involving more than 6,500 kids emphasize the importance of cardiorespiratory health in childhood, and support physical fitness initiatives in schools, according to lead author Katharina Köble, MSc, of the Technical University of Munich (Germany), and colleagues.

“Recent studies show that only a few children meet the recommendations of physical activity,” the investigators wrote in Journal of Clinical Medicine.

While the health benefits of physical activity are clearly documented, Ms. Köble and colleagues noted that typical measures of activity, such as accelerometers or self-reported questionnaires, are suboptimal research tools.

“Physical fitness is a more objective parameter to quantify when evaluating health promotion,” the investigators wrote. “Furthermore, cardiorespiratory fitness as part of physical fitness is more strongly related to risk factors of cardiovascular disease than physical activity.”

According to the investigators, physical fitness has also been linked with better concentration and HRQOL, but never in the same population of children.

The new study aimed to address this knowledge gap by assessing 6,533 healthy children aged 6-10 years, approximately half boys and half girls. Associations between physical fitness, concentration, and HRQOL were evaluated using multiple linear regression analysis in participants aged 9-10 years.

Physical fitness was measured using a series of challenges, including curl-ups (pull-ups with palms facing body), push-ups, standing long jump, handgrip strength measurement, and Progressive Aerobic Cardiovascular Endurance Run (PACER). Performing the multistage shuttle run, PACER, “requires participants to maintain the pace set by an audio signal, which progressively increases the intensity every minute.” Results of the PACER test were used to estimate VO2max.

Concentration was measured using the d2-R test, “a paper-pencil cancellation test, where subjects have to cross out all ‘d’ letters with two dashes under a time limit.”

HRQOL was evaluated with the KINDL questionnaire, which covers emotional well-being, physical well-being, everyday functioning (school), friends, family, and self-esteem.

Analysis showed that physical fitness improved with age (P < .001), except for VO2max in girls (P = .129). Concentration also improved with age (P < .001), while HRQOL did not (P = .179).

Among children aged 9-10 years, VO2max scores were strongly associated with both HRQOL (P < .001) and concentration (P < .001).

“VO2max was found to be one of the main factors influencing concentration levels and HRQOL dimensions in primary school children,” the investigators wrote. “Physical fitness, especially cardiorespiratory performance, should therefore be promoted more specifically in school settings to support the promotion of an overall healthy lifestyle in children and adolescents.”
 

Findings are having a real-word impact, according to researcher

In an interview, Ms. Köble noted that the findings are already having a real-world impact.

“We continued data assessment in the long-term and specifically adapted prevention programs in school to the needs of the school children we identified in our study,” she said. “Schools are partially offering specific movement and nutrition classes now.”

In addition, Ms. Köble and colleagues plan on educating teachers about the “urgent need for sufficient physical activity.”

“Academic performance should be considered as an additional health factor in future studies, as well as screen time and eating patterns, as all those variables showed interactions with physical fitness and concentration. In a subanalysis, we showed that children with better physical fitness and concentration values were those who usually went to higher education secondary schools,” they wrote.
 

 

 

VO2max did not correlate with BMI

Gregory Weaver, MD, a pediatrician at Cleveland Clinic Children’s, voiced some concerns about the reliability of the findings. He noted that VO2max did not correlate with body mass index or other measures of physical fitness, and that using the PACER test to estimate VO2max may have skewed the association between physical fitness and concentration.

“It is quite conceivable that children who can maintain the focus to perform maximally on this test will also do well on other tests of attention/concentration,” Dr. Weaver said. “Most children I know would have a very difficult time performing a physical fitness test which requires them to match a recorded pace that slowly increases overtime. I’m not an expert in the area, but it is my understanding that usually VO2max tests involve a treadmill which allows investigators to have complete control over pace.”

Dr. Weaver concluded that more work is needed to determine if physical fitness interventions can have a positive impact on HRQOL and concentration.

“I think the authors of this study attempted to ask an important question about the possible association between physical fitness and concentration among school aged children,” Dr. Weaver said in an interview. “But what is even more vital are studies demonstrating that a change in modifiable health factors like nutrition, physical fitness, or the built environment can improve quality of life. I was hoping the authors would show that an improvement in VO2max over time resulted in an improvement in concentration. Frustratingly, that is not what this article demonstrates.”

The investigators and Dr. Weaver reported no conflicts of interest.

Protease inhibitors increase small-for-gestational-age but not other pregnancy risks

Article Type
Changed

Pregnant women with HIV can be reassured that protease inhibitors are safer than previously thought in terms of risk to the fetus, according to research from the National Perinatal Epidemiology Unit (NPEU) at Oxford Population Health, a research institute based at the University of Oxford (England).

Antiretroviral therapy (ART) is recommended for all pregnant women living with HIV and plays a crucial role both in improving maternal health and in reducing transmission of HIV from mother to child. However, there has been a critical lack of evidence about the effects of ART on the risk of adverse pregnancy outcomes, with particular concern about protease inhibitors.

Current guidelines recommend that protease inhibitor-based therapies should be used in pregnancy only if first-line treatments (such as integrase and reverse-transcriptase based treatments) are either unsuitable or unavailable. These guidelines also often advise against the use of a specific protease inhibitor, lopinavir/ritonavir, citing an increased risk of preterm birth. However, such advice may restrict treatment options for pregnant women with HIV on the basis of limited evidence.
 

Largest review to date

The NPEU researchers, therefore, conducted the largest systematic review to date of adverse perinatal outcomes after a range of antiretroviral therapies. It included 34 cohort studies published between 1980 and 2020 and involving over 57,000 pregnant women with HIV in 22 different countries. The review, published in eClinicalMedicine, looked for evidence of 11 perinatal outcomes:

  • Preterm birth, very preterm birth, and spontaneous preterm birth
  • Low birth weight, very low birth weight, term low birth weight, and preterm low birth weight
  • Small for gestational age and very small for gestational age
  • Stillbirth, and neonatal death

Using pairwise random-effects meta-analyses, researchers compared protease inhibitor versus non-protease inhibitor-based ART, as well as specifically looking at the comparative risks associated with different protease inhibitor regimens.

They found that protease inhibitor-based ART significantly increased the risk of small or very small for gestational age babies, with relative risks of 1.24 (95% confidence interval, 1.08-1.43; I2 = 66.7%) and 1.40 (95% CI, 1.09-1.81; I2 = 0.0%), respectively. However there were no significant differences in other adverse pregnancy outcomes for protease inhibitors, compared with other therapies.

In addition, researchers found no significant differences in perinatal outcomes between ART regimens containing lopinavir/ritonavir, atazanavir/ritonavir, or darunavir/ritonavir, which are the most frequently used protease inhibitors.
 

No increased risk of preterm birth

Senior author Dr. Joris Hemelaar, senior clinical research fellow at the NPEU and honorary consultant in obstetrics at the John Radcliffe Hospital, Oxford (England), said: “Antiretroviral therapy in pregnancy has clear benefits for maternal health and prevention of HIV transmission to the child, but our study has shown for the first time that protease inhibitors are associated with babies being small or very small for their gestational age.”

“However, there was no increased risk of preterm birth, or any other adverse pregnancy outcomes. This means protease inhibitors remain an important option for pregnant women living with HIV if other treatments are unsuitable, for example due to drug resistance, or unavailable. The evidence presented here indicates that the commonly used protease inhibitors atazanavir, lopinavir, and darunavir are comparable with regard to perinatal outcomes, which should inform international treatment guidelines.”

Over 70% of the studies assessed were conducted in high-income countries, and Dr. Hemelaar added that there is an urgent need for more research on pregnancy outcomes after different ART in low- to middle-income countries, where the burden of HIV is highest.

Professor Yvonne Gilleece, a spokesperson for the British HIV Association (BHIVA) and immediate past chair of the BHIVA guidelines on the management of HIV in pregnancy and the postpartum period commented: “Pregnancy is a unique life situation in which we must consider the safety of both the birthing parent and the baby. Due to ongoing under-representation of all women in clinical trials, but particularly pregnant women, we do not have enough evidence on which to base all our management decisions. This systematic review includes large numbers of pregnant women living with HIV and can, therefore, improve an informed discussion regarding the safety of the use of protease inhibitors during pregnancy.”

Dr. Hemelaar told Medscape UK: “Many international treatment guidelines cite adverse pregnancy outcomes, in particular preterm birth, associated with protease inhibitor (PI)-drugs as a reason for caution for their use in pregnancy. However, PI drugs are not associated with preterm birth in our analysis. This suggests that PI drugs may not be as detrimental as previously thought (and we found no differences between different PI drugs used), and, hence, these drugs may have a more favourable profile for use in pregnancy.

“However, many other aspects of treatment, including the extent to which the virus can be suppressed, adverse drug effects, adherence to drug prescriptions, antiretroviral drug resistance, drug interactions, drug cost, and availability, should also be taken into account by clinicians and guideline development committees.”

Steroids counter ataxia telangiectasia

Article Type
Changed

A novel therapy for ataxia telangiectasia that delivers dexamethasone sodium phosphate (DSP) through autologous red blood cells has shown promise in a phase 3 clinical trial.

The disease is an autosomal recessive disorder caused by mutations in the ATM gene, which is critical to the response to cellular insults such as DNA breaks, oxidative damage, and other forms of stress. The result is clinical manifestations that range from a suppressed immune system to organ damage and neurological symptoms that typically lead patients to be wheelchair bound by their teenage years.

“It’s really multisystem and a very, very difficult disease for people to live with,” Howard M. Lederman, MD, PhD, said in an interview. Dr. Lederman is a coauthor of the study, which was presented by Stefan Zielen, PhD, professor at the University of Goethe, at the 2022 annual meeting of the American Academy of Neurology.

Various therapies have been developed to improve immunodeficiency, lung disease, and some of the other clinical aspects of the condition, but there is no treatment for its neurological effects. “There’s not really been a good animal model, which has been a big problem in trying to test drugs and design treatment trials,” said Dr. Lederman, professor of pediatrics and medicine at Johns Hopkins University, Baltimore.

The new results may change that. “In the children under the age of 9, there was really a very clear slowdown in the neurodegeneration, and specifically the time that it took for them to lose the ability to ambulate. It’s very exciting, because it’s the first time that anybody has really shown in a double-blind, placebo-controlled, large phase 3 study that any drug has been able to do this. And there were really no steroid side effects, which is the other really remarkable thing about this study,” said Dr. Lederman.

The therapy grew out of a study by researchers in Italy who treated pediatric ataxia telangiectasia patients with corticosteroids and found some transitory improvements in gross motor function, but concerns about long-term exposure to steroids limited its application. EryDel, which specializes in encapsulating therapeutics in red blood cells, became interested and developed a formulation using the patient’s own red blood cells infused with DSP. Reinfused to the patients, the red blood cells slowly release the steroid.

It isn’t clear how dexamethasone works. There are data suggesting that it might lead to transcription of small pieces of the ATM protein, “but that has really not been nailed down in any way at this point. Corticosteroids act on all kinds of cells in all kinds of ways, and so there might be a little bit of this so-called mini-ATM that’s produced, but that may or may not be related to the way in which corticosteroids have a beneficial effect on the rate of neurodegeneration,” said Dr. Lederman.

The treatment process is not easy. Children must have 50-60 cc of blood removed. Red blood cells treated to become porous are exposed to DSP, and then resealed. Then the cells are reinfused. “The whole process takes from beginning to end probably about 3 hours, with a really experienced team of people doing it. And it’s limiting because it’s not easy to put in an IV and take 50 or 60 cc of blood out of children much younger than 5 or 6. The process is now being modified to see whether we could do it with 20 to 30 cc instead,” said Dr. Lederman.
 

 

 

A ‘promising and impressive’ study

The study is promising, according to Nicholas Johnson, MD, who comoderated the session where the study was presented. “They were able to show a slower rate of neurological degeneration or duration on both the lower and higher dose compared with the placebo. This is promising and impressive, in the sense that it’s a really large (trial) for a rare condition,” Dr. Johnson, vice chair of research at Virginia Commonwealth University, Richmond, said in an interview.

The study included 164 patients Europe, Australia, Israel, Tunisia, India, and the United States, who received 5-10 mg dexamethasone, 14-22 mg DSP, or placebo. Mean ages in each group ranged from 9.6 to 10.4 years.

In an intention-to-treat analysis, modified International Cooperative Ataxia Rating Scale (mICARS) scores trended toward improvement in the low-dose (–1.37; P = .0847) and high-dose groups (–1.40; P = .0765) when determined by central raters during the COVID-19 pandemic. There was also a trend toward improvement when determined by local raters in the low dose group (–1.73; P = .0720) and a statistically significant change in the high dose group (–2.11; P = .0277). The researchers noted some inconsistency between local and central raters, due to inconsistency of videography and language challenges for central raters.

An intention-to-treat analysis of a subgroup of 89 patients age 6-9, who were compared with natural history data from 245 patients, found a deterioration of mICARS of 3.7 per year, compared with 0.92 in the high-dose group, for a reduction of 75% (P = .020). In the high-dose group, 51.7% had a minimal or significant improvement compared with baseline according to the Clinical Global Impression of Change, as did 29.0% on low dose, and 27.6% in the placebo group.

A novel therapy for ataxia telangiectasia that delivers dexamethasone sodium phosphate (DSP) through autologous red blood cells has shown promise in a phase 3 clinical trial.

The disease is an autosomal recessive disorder caused by mutations in the ATM gene, which is critical to the response to cellular insults such as DNA breaks, oxidative damage, and other forms of stress. The result is clinical manifestations that range from a suppressed immune system to organ damage and neurological symptoms that typically lead patients to be wheelchair bound by their teenage years.

“It’s really multisystem and a very, very difficult disease for people to live with,” Howard M. Lederman, MD, PhD, said in an interview. Dr. Lederman is a coauthor of the study, which was presented by Stefan Zielen, PhD, professor at the University of Goethe, at the 2022 annual meeting of the American Academy of Neurology.

Various therapies have been developed to improve immunodeficiency, lung disease, and some of the other clinical aspects of the condition, but there is no treatment for its neurological effects. “There’s not really been a good animal model, which has been a big problem in trying to test drugs and design treatment trials,” said Dr. Lederman, professor of pediatrics and medicine at Johns Hopkins University, Baltimore.

The new results may change that. “In the children under the age of 9, there was really a very clear slowdown in the neurodegeneration, and specifically the time that it took for them to lose the ability to ambulate. It’s very exciting, because it’s the first time that anybody has really shown in a double-blind, placebo-controlled, large phase 3 study that any drug has been able to do this. And there were really no steroid side effects, which is the other really remarkable thing about this study,” said Dr. Lederman.

The therapy grew out of a study by researchers in Italy who treated pediatric ataxia telangiectasia patients with corticosteroids and found some transitory improvements in gross motor function, but concerns about long-term exposure to steroids limited its application. EryDel, which specializes in encapsulating therapeutics in red blood cells, became interested and developed a formulation using the patient’s own red blood cells infused with DSP. Reinfused to the patients, the red blood cells slowly release the steroid.

It isn’t clear how dexamethasone works. There are data suggesting that it might lead to transcription of small pieces of the ATM protein, “but that has really not been nailed down in any way at this point. Corticosteroids act on all kinds of cells in all kinds of ways, and so there might be a little bit of this so-called mini-ATM that’s produced, but that may or may not be related to the way in which corticosteroids have a beneficial effect on the rate of neurodegeneration,” said Dr. Lederman.

The treatment process is not easy. Children must have 50-60 cc of blood removed. Red blood cells treated to become porous are exposed to DSP, and then resealed. Then the cells are reinfused. “The whole process takes from beginning to end probably about 3 hours, with a really experienced team of people doing it. And it’s limiting because it’s not easy to put in an IV and take 50 or 60 cc of blood out of children much younger than 5 or 6. The process is now being modified to see whether we could do it with 20 to 30 cc instead,” said Dr. Lederman.

JIA disease activity, disability linked to social factors

Article Type
Changed

For children with polyarticular juvenile idiopathic arthritis (pJIA), functional disability lasts longer and disease activity is increased among those who belong to a racial/ethnic minority or come from homes with low household income or low family education, according to a study published online in Pediatric Rheumatology. The findings also initially revealed a higher likelihood of functional disability among those living in a poorer community, but that association lost statistical significance after adjustment for confounders.

“We chose community poverty level as the primary predictor for outcomes in pJIA because the socioeconomic context of communities and neighborhoods affects the characteristics of the social, service, and physical environments to which all residents are exposed regardless of their own socioeconomic position and may have a greater negative impact on those with fewer individual resources,” the authors write. “While community poverty level was not associated with an increase in odds of moderate-to-severe disease activity, those with high community poverty level did have higher disease activity scores (0.33 points greater on average than those with low community poverty level, in adjusted analysis).”

Nayimisha Balmuri, MD, an assistant professor of pediatrics at Johns Hopkins Medicine and study coauthor, told this news organization that anecdotal experience from everyday practice has shown that “patients with myriad social determinants of health stacked against them present sicker, take longer to present, and require far more aggressive therapies and follow-up,” which wreaks havoc in terms of disease activity. “It’s really difficult, then, to play catch-up to other cohorts of patients,” Dr. Balmuri added.
 

Disparities in outcomes persist

A key clinical take-home message from these findings is that the differences in clinical outcomes are relevant throughout the entire year of therapy, Dr. Balmuri said. “Patients get better; however, they don’t get better the same,” she said, and this is because of a variety of reasons. “Getting in the door is one of [those reasons] but then continuing to follow-up care is another.” For general practitioners, it’s especially important to refer patients who complain of joint pains to a specialist and to then follow up to be sure they’re improving and they’re getting the care they need.

For pediatric rheumatologists and subspecialists, “it’s important for us to realize that the disparity doesn’t end when patients come into your door to begin with,” Dr. Balmuri said. “It continues over the short term and far past that into adulthood.”



Candace Feldman, MD, MPH, ScD, an assistant professor of medicine in the Division of Rheumatology, Inflammation, and Immunity at Brigham and Women’s Hospital, Boston, told this news organization that the research “provides an important foundation to the study of the impact of social determinants of health on disease activity and disability among children with JIA. Individuals with rheumatic conditions should be screened for social determinants of health–related needs, and infrastructure should exist within the rheumatology clinic to help address the needs uncovered.” Dr. Feldman was not involved in the study.

In addition to the results’ clinical significance, Dr. Feldman also noted the policy implications of these findings. “Physicians should advocate for efforts to dismantle structural racism, to address income inequality, and to mitigate the effects of climate change, which also disproportionately affect historically marginalized populations,” Dr. Feldman said. Although this study focused predominantly on poverty, she noted that financial insecurity, food insecurity, homelessness, or housing instability were other social determinants of health to consider in future research.

Dr. Balmuri and William Daniel Soulsby, MD, a clinical fellow in pediatric rheumatology at the University of California, San Francisco, who is the study’s lead author, said they focused on poverty in this study not only because it’s so understudied in patients with pJIA but also because research in adults with lupus has found that leaving poverty was associated with a reversal of accrued disease damage.

 

 

Interactions of social determinants

The authors analyzed retrospective data from 1,684 pediatric patients in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) registry covering the period of April 2015 to February 2020. All study participants had been diagnosed with pJIA. Symptom onset occurred before age 16, and at least five joints were involved. The authors excluded patients who had been diagnosed with other systemic inflammatory or autoimmune diseases.

The authors defined exposure to a high level of community poverty as living in a ZIP code where at least 20% of residents lived at or below the federal poverty level. The authors also collected data on household income, although these data were missing for more than a quarter of participants (27%) and were therefore included only in sensitivity analyses. They used the clinical Juvenile Arthritis Disease Activity Score–10 (cJADAS-10) and the Child Health Assessment Questionnaire (CHAQ) to assess disease activity and disability at baseline and 6 and 12 months later. A cutoff of 2.5 on the cJADAS-10 distinguished mild disease activity from moderate to high disease activity, and a CHAQ score of 0.25 was the cutoff for having functional disability.

Among those who reported household income, just over half the cohort had an income of at least $50,000. The study population was 74% White, and more non-White patients lived in high-poverty communities (36.4%) than did White patients (21.3%). Patients whose families had no more than a high school education (23.1% vs. 13.7%) and those with public insurance (43.0% vs. 21.5%) were also over-represented in poorer communities.



The median cJADAS-10 scores declined overall during patients’ first year of therapy. However, those with public insurance, a lower family education level, or residency in poorer communities made up the greatest proportion of patients who continued to have moderate to severe disease activity a year after diagnosis.

The unadjusted calculations showed that children living in high community poverty had 1.8 times greater odds of functional disability (odds ratio, 1.82; P < .001). However, after adjustment for age, sex, race/ethnicity, insurance status, family education, rheumatoid factor, and cyclic citrullinated peptide antibody, the association lost statistical significance (P = .3). Community poverty level was not associated with disease activity before or after adjustment.

“Race was adjusted for as a confounder; however, the association between race/ethnicity and social determinants of health is likely more complex,” Dr. Feldman said. “Interactions, for example, between individual race and area-level poverty could be investigated.”

Odds of persistent function disability were 1.5 times greater for children with public insurance (adjusted OR, 1.56; P = .023) and 1.9 times greater for those whose families had a lower education level (aOR, 1.89; P = .013). Children whose race/ethnicity was indicated as being other than White had more than double the odds of higher disease activity (aOR, 2.48; P = .002) and were nearly twice as likely to have persistent functional disability (aOR, 1.91; P = .031).

Future directions

Dr. Soulsby was struck by the difference in statistical significance between individual-level poverty, as measured by household income, and community-level poverty. “It’s interesting because it may suggest that both of these forms of poverty are different and have different impacts on disease,” he said. Dr. Balmuri elaborated on the nuances and interactions that exist with social determinants of health and how objective outcomes, such as disease activity as measured by clinical tools, can differ from subjective outcomes, such as patients’ reports of pain, daily disability, and social experiences.

“The human condition is far more complicated, unfortunately, than any dataset could have on their own collected,” Dr. Balmuri said. She said she plans to expand her pJIA research into other social determinants of health. “It’s first about getting people’s eyes and minds open to something we see every day that, for some reason, sometimes people are blinded to, [using] the data that we do have, and then our hope is to build upon that.”

Dr. Feldman noted that ZIP codes, which were used as a proxy for community poverty, may not provide the best perspective regarding a patient’s neighborhood, because significant variation may exist within a single ZIP code, which is something the authors noted as well. The investigators were limited in the data available from the registry, and Dr. Balmuri and Dr. Soulsby suggested that 9-digit ZIP codes or census tracts might better capture neighborhood deprivation.

The research was funded by the Arthritis Foundation and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Feldman has received research support from Pfizer and the Bristol-Myers Squibb Foundation. Dr. Soulsby and Dr. Balmuri have disclosed no relevant financial relationships.

A cutoff of 2.5 on the cJADAS-10 distinguished mild disease activity from moderate to high disease activity, and a CHAQ score of 0.25 was the cutoff for having functional disability.

Among those who reported household income, just over half the cohort had an income of at least $50,000. The study population was 74% White, and more non-White patients lived in high-poverty communities (36.4%) than did White patients (21.3%). Patients whose families had no more than a high school education (23.1% vs. 13.7%) and those with public insurance (43.0% vs. 21.5%) were also over-represented in poorer communities.



The median cJADAS-10 scores declined overall during patients’ first year of therapy. However, those with public insurance, a lower family education level, or residency in poorer communities made up the greatest proportion of patients who continued to have moderate to severe disease activity a year after diagnosis.

The unadjusted calculations showed that children living in high community poverty had 1.8 times greater odds of functional disability (odds ratio, 1.82; P < .001). However, after adjustment for age, sex, race/ethnicity, insurance status, family education, rheumatoid factor, and cyclic citrullinated peptide antibody, the association lost statistical significance (P = .3). Community poverty level was not associated with disease activity before or after adjustment.

“Race was adjusted for as a confounder; however, the association between race/ethnicity and social determinants of health is likely more complex,” Dr. Feldman said. “Interactions, for example, between individual race and area-level poverty could be investigated.”

Odds of persistent function disability were 1.5 times greater for children with public insurance (adjusted OR, 1.56; P = .023) and 1.9 times greater for those whose families had a lower education level (aOR, 1.89; P = .013). Children whose race/ethnicity was indicated as being other than White had more than double the odds of higher disease activity (aOR, 2.48; P = .002) and were nearly twice as likely to have persistent functional disability (aOR, 1.91; P = .031).

Future directions

Dr. Soulsby was struck by the difference in statistical significance between individual-level poverty, as measured by household income, and community-level poverty. “It’s interesting because it may suggest that both of these forms of poverty are different and have different impacts on disease,” he said. Dr. Balmuri elaborated on the nuances and interactions that exist with social determinants of health and how objective outcomes, such as disease activity as measured by clinical tools, can differ from subjective outcomes, such as patients’ reports of pain, daily disability, and social experiences.

“The human condition is far more complicated, unfortunately, than any dataset could have on their own collected,” Dr. Balmuri said. She said she plans to expand her pJIA research into other social determinants of health. “It’s first about getting people’s eyes and minds open to something we see every day that, for some reason, sometimes people are blinded to, [using] the data that we do have, and then our hope is to build upon that.”

Dr. Feldman noted that ZIP codes, which were used as a proxy for community poverty, may not provide the best perspective regarding a patient’s neighborhood, because significant variation may exist within a single ZIP code, which is something the authors noted as well. The investigators were limited in the data available from the registry, and Dr. Balmuri and Dr. Soulsby suggested that 9-digit ZIP codes or census tracts might better capture neighborhood deprivation.

The research was funded by the Arthritis Foundation and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Feldman has received research support from Pfizer and the Bristol-Myers Squibb Foundation. Dr. Soulsby and Dr. Balmuri have disclosed no relevant financial relationships.

Preterm C-sections, induced deliveries dropped during COVID-19 pandemic

Article Type
Changed

Premature births from cesarean (C-section) and induced deliveries dropped abruptly by 6.5% from the projected number in the first month of the COVID-19 pandemic and stayed at the lower rate consistently throughout the year, researchers have found.

Results of the study, led by Daniel Dench, PhD, assistant professor at the Georgia Institute of Technology School of Economics in Atlanta, were published online in Pediatrics.

Dr. Daniel Dench

The authors say their findings help answer the question of whether numbers of preterm (less than 37 weeks gestation) C-sections and induced deliveries would change if women didn’t see their physicians during pregnancy as often, especially in person, and raise the question of whether some birth interventions by physicians may not be necessary. The pandemic gave researchers a natural, ethical way to study the question.

The researchers found that in March 2020 – the start of business closures and stay-at-home orders around the country – preterm births from C-sections or induced deliveries immediately fell from the forecast number for the month by 0.4 percentage points. For the rest of 2020, the number remained on average 0.35 percentage points below the numbers predicted.

That means 350 fewer preterm C-sections and induced deliveries per 100,000 live births, or 10,000 fewer overall, the authors said.

Dr. Dench told this publication the numbers for those births had been steady from January 2010 to February 2020, but the pattern “diverges from this trend very clearly beginning exactly in March 2020 and does not return to trend by December 2020.”

Meanwhile, during the study period, the number of full-term cesarean and induced deliveries stayed steady and started to increase slightly in 2020. Researchers also adjusted for seasonality as, for example, preterm births are higher on average in February than in March.

So far, Dr. Dench said in a press release, it’s not clear whether the lower numbers mean physicians didn’t deliver babies that ended up surviving in the womb anyway or if they missed some that would die in the womb without intervention.

To better understand those implications, Dr. Dench says he is turning to fetal death records for March-December 2020 and he said he expects to have those results analyzed by the end of the year.

If there was no change in fetal deaths at the same time as the drop in preterm births, Dr. Dench said, that could point to physician interventions that may not have been necessary.

Mya R. Zapata, MD, an obstetrician-gynecologist with UCLA Health, who was not involved with the study, told this publication that checking the fetal deaths is a good start and an objective outcome in answering the question, but she points out there are other outcomes that will take a deeper analysis, such as whether there are differences later in developmental outcomes after fewer physician visits.

“It’s always a good question for health care,” she said, “are we doing more than we need to?”

Dr. Zapata is the obstetrics service chief for UCLA’s labor and delivery unit and was an integral part of decision-making as to what services were essential and for which patients. She said the fewer visits and fewer ultrasounds the researchers describe fit with what ob.gyns. at UCLA experienced as the pandemic hit.

“We really tried to hone in on people who were at highest risk for an adverse outcome,” she said. “I still have the question of whether there were things we missed in low-risk people. It will take time to get the entire answer. But it does make us reflect that perhaps less intervention could be better for patients and easier. It’s our job in medicine to keep asking the question of what is essential and safe and not just continue with current practice because that’s what we’ve always done.”

The amount of data gave the researchers an unusual view. They studied 38,891,271 singleton births in the United States from 2010 to 2020 with data from the National Center for Health Statistics.

“If you look at 1,000 births in a single hospital, or even at 30,000 births across a hospital system, you wouldn’t be able to see the drop as clearly,” Dr. Dench said. “The drop we detected is a huge change, but you might miss it in a small sample.”

The researchers acknowledge a limitation of the study is that half of all preterm C-sections and induced deliveries happen because of a ruptured membrane, a spontaneous cause. Those instances can’t be distinguished from the ones caused by doctors’ interventions in this study.

“Still, these findings are significant because the causes for preterm births are not always known,” the authors wrote in the press release.

The study authors and Dr. Zapata reported no relevant financial relationships.

Abnormal growth of the amygdala in infants tied to autism

Article Type
Changed

A new study suggests that overgrowth of the amygdala in infants during the first 6-12 months of life is tied to a later diagnosis of autism spectrum disorder (ASD).

“The faster the amygdala grew in infancy, the more social difficulties the child showed when diagnosed with autism a year later,” first author Mark Shen, PhD, assistant professor of psychiatry and neuroscience, University of North Carolina, Chapel Hill, told this news organization.

The study was published online  in the American Journal of Psychiatry.
 

Unique to autism

The amygdala plays a key role in processing memory, emotional responses, and decisionmaking. 

It’s long been known that the amygdala is abnormally large in school-aged children with ASD, but until now, it was not known precisely when aberrant amygdala growth happens, what the clinical consequences may be, and whether amygdala overgrowth is unique to autism.

To investigate, Dr. Shen and colleagues evaluated 1,099 longitudinal MRI scans obtained during natural sleep at 6, 12, and 24 months of age in 408 infants in the Infant Brain Imaging Study (IBIS) Network.

The cohort included 58 infants at high likelihood of developing ASD who were later diagnosed with the disorder, 212 infants at high likelihood of ASD who did not develop ASD, 109 typically-developing control infants, and 29 infants with fragile X syndrome.

At 6 months, infants who developed ASD had typically sized amygdala volumes but showed significantly faster amygdala growth between 6 and 24 months, such that by 12 months the ASD group had significantly larger amygdala volume (Cohen’s d = 0.56), compared with all other groups.

Amygdala growth rate between 6 and 12 months was significantly associated with greater social deficits at 24 months when the children were diagnosed with ASD.

“We found that the amygdala grows too rapidly between 6 and 12 months of age, during a presymptomatic period in autism, prior to when the diagnostic symptoms of autism (social difficulties and repetitive behaviors) are evident and lead to the later diagnosis of autism,” Dr. Shen said in an interview.

This brain growth pattern appears to be unique to autism, as babies with the genetic disorder fragile X syndrome – another neurodevelopmental condition – showed a markedly different brain growth pattern: no differences in amygdala growth but enlargement of a different brain structure, the caudate, which was linked to increased repetitive behaviors, the investigators found.
 

Earlier intervention

Prior research has shown that children who are later diagnosed with ASD often display problems in infancy with how they attend to visual stimuli in their surroundings.

These early problems with processing visual and sensory information may put increased stress on the amygdala, potentially leading to amygdala hyperactivity, deficits in pruning dendritic connections, and overgrowth, Dr. Shen and colleagues hypothesize.

Amygdala overgrowth has also been linked to chronic stress in studies of other psychiatric conditions, such as depression and anxiety, and may provide a clue to understanding this observation in infants who later develop autism.

“This research suggests that an optimal time to begin supports for children who are at the highest likelihood of developing autism may be during the first year of life: to improve early precursors to social development, such as sensory processing, in babies even before social difficulties arise,” Dr. Shen said.

Cyrus A. Raji, MD, PhD, assistant professor of radiology and neurology, Washington University, St. Louis, said, “What makes this study important is the finding of abnormally increased amygdala growth rate in autism using a longitudinal design that focuses on earlier development.”

“While we are typically used to understanding brain structure as abnormally decreasing over time in certain disorders like Alzheimer’s disease, this study challenges us to understand that too much brain volume growth can also be abnormal in specific conditions,” Dr. Raji added.

This research was supported by grants from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institute of Environmental Health Sciences, and National Institute of Mental Health, along with Autism Speaks and the Simons Foundation. Dr. Shen and Dr. Raji have disclosed no relevant financial relationships.

Could AI tool identify type 1 diabetes earlier in childhood?

Article Type
Changed

An artificial intelligence (AI)–based predictive tool may be able to identify type 1 diabetes in children earlier, before they are diagnosed as a result of potentially fatal diabetic ketoacidosis (DKA), suggests a new U.K. study.

The tool was developed by Julia Townson, PhD, senior trial manager in children and young people at Cardiff University, U.K., and colleagues.

Her team had previously shown that children who develop type 1 diabetes have a different pattern of contact with primary care in the 6 months leading up to their diagnosis.

Symptoms of type 1 diabetes include going to the toilet more and being thirsty, tired, and thin, but GPs can still miss these signs.

So they tested different combinations of factors from GP records – such as urinary tract infections or bedwetting, being prescribed antibiotics or family history of type 1 diabetes – in approximately 1 million children in Wales, more than 2,000 of whom had been diagnosed with type 1 diabetes, to train the predictive tool.

In a separate study of around 1.5 million children in England, they found that the algorithm could identify type 1 diabetes in 75% of affected children 11 days earlier than without the tool, if it was set up as an alert at every one in 10 general practice consultations.

Dr. Townson presented her research at the recent Diabetes UK Professional Conference 2022.
 

One-quarter of kids diagnosed with type 1 diabetes are in DKA

During her presentation, Dr. Townson explained that, in the U.K., approximately 25% of children with type 1 diabetes are diagnosed while they are in DKA, a figure that has remained unchanged for 25 years.

“We know that delayed- and misdiagnosis are the most common reasons for a child presenting in DKA at diagnosis,” she said. “And of course, the reason why it’s so important to prevent presentation in DKA is because of the considerable morbidity and potentially mortality associated with it.”

Indeed, with a simple internet search, Dr. Townson was able to identify four children who lost their lives to DKA in the past 8 years in the U.K.

“It’s encouraging to see that this research could save many families a potentially traumatic trip to the hospital by helping family doctors diagnose type 1 diabetes more rapidly,” Conor McKeever, research communications manager at the type 1 diabetes charity JDRF, told this news organization.

“This approach could go hand-in-hand with population screening, which has the potential to identify people at high risk of developing type 1 diabetes before they experience any symptoms,” he added. The hope is that “far fewer families experience DKA at the start of their type 1 diabetes journey.”

“Finding a way to catch the condition and treat it early could help to avoid emergency hospital treatment and save lives,” agreed Lucy Chambers, PhD, head of research communications at Diabetes UK, which funded the research.
 

How to integrate tool into GP systems

“We are now looking to see how this tool might work with primary care computer systems,” Dr. Townson said. She said in an interview that they are exploring “how it could be ‘bolted’ on to the GP’s software system.”

“It works on many different levels, but one level is frequency of consultations in relation to the frequency of previous consultations, so it needs to be able to ‘look’ through the electronic health records, at the time of the consultation, to come up with a predictive score.”

Dr. Townson said it is not clear how “easy it will be to integrate it into current systems, and I do not know of any other machine learning applications which have been used like this in primary care.”

“But we are hopeful, and we have started to contact companies who are involved in providing these systems.”

The research was funded by Diabetes UK, and the Clinical Trials Unit was funded by Health and Care Research Wales. No relevant financial relationships were declared.

An artificial intelligence (AI)–based predictive tool may be able to identify type 1 diabetes in children earlier, before they are diagnosed as a result of potentially fatal diabetic ketoacidosis (DKA), suggests a new U.K. study.

The tool was developed by Julia Townson, PhD, senior trial manager in children and young people at Cardiff University, U.K., and colleagues.

Her team had previously shown that children who develop type 1 diabetes have a different pattern of contact with primary care in the 6 months leading up to their diagnosis.

Symptoms of type 1 diabetes include going to the toilet more and being thirsty, tired, and thin, but GPs can still miss these signs.

So they tested different combinations of factors from GP records – such as urinary tract infections or bedwetting, being prescribed antibiotics or family history of type 1 diabetes – in approximately 1 million children in Wales, more than 2,000 of whom had been diagnosed with type 1 diabetes, to train the predictive tool.

In a separate study of around 1.5 million children in England, they found that the algorithm could identify type 1 diabetes in 75% of affected children 11 days earlier than without the tool, if it was set up as an alert at every one in 10 general practice consultations.

Dr. Townson presented her research at the recent Diabetes UK Professional Conference 2022.
 

One-quarter of kids diagnosed with type 1 diabetes are in DKA

During her presentation, Dr. Townson explained that, in the U.K., approximately 25% of children with type 1 diabetes are diagnosed while they are in DKA, a figure that has remained unchanged for 25 years.

“We know that delayed- and misdiagnosis are the most common reasons for a child presenting in DKA at diagnosis,” she said. “And of course, the reason why it’s so important to prevent presentation in DKA is because of the considerable morbidity and potentially mortality associated with it.”

Indeed, with a simple internet search, Dr. Townson was able to identify four children who lost their lives to DKA in the past 8 years in the U.K.

“It’s encouraging to see that this research could save many families a potentially traumatic trip to the hospital by helping family doctors diagnose type 1 diabetes more rapidly,” Conor McKeever, research communications manager at the type 1 diabetes charity JDRF, told this news organization.

“This approach could go hand-in-hand with population screening, which has the potential to identify people at high risk of developing type 1 diabetes before they experience any symptoms,” he added. The hope is that “far fewer families experience DKA at the start of their type 1 diabetes journey.”

“Finding a way to catch the condition and treat it early could help to avoid emergency hospital treatment and save lives,” agreed Lucy Chambers, PhD, head of research communications at Diabetes UK, which funded the research.

Children and teens with food allergies face quality-of-life issues

Article Type
Changed

Children and adolescents with food allergies appear to fare worse physically, socially, and emotionally, and have poorer overall health-related quality of life (HRQL) than their food allergy–free peers, a new systematic review suggests.

“Findings from the current review suggest that food allergy has a negative impact on the HRQL of children and teens, particularly older children and those with severe food allergy,” the authors wrote. “By comparison, the link between food allergy and psychosocial functioning is less clear.

“Evidence from the qualitative literature suggests that the burden of childhood food allergy largely stems from worries surrounding exposures outside of the home and the social consequences of the condition,” they added.

Lead study author Michael A. Golding, a research coordinator at Children’s Hospital Research Institute of Manitoba in Winnipeg, Canada, and colleagues searched PubMed, Scopus, PsycInfo, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases on several days between November 2019 and March 2021 for peer-reviewed articles published in English in any year.  

They reviewed articles focused on HRQL, psychological health, or social well-being in children and teens with food allergy from birth through 19 years of age. Food allergy comprised both immunoglobulin E (IgE)-mediated food allergies and non-IgE-mediated allergies, including food protein–induced enterocolitis, enteropathy, and proctocolitis.

From the 3,789 publications the researchers screened, they included 8,202 patients in 45 studies in their quantitative synthesis and 186 patients in 9 studies in their qualitative synthesis. Using a segregated, mixed research synthesis design, they analyzed and synthesized the quantitative and qualitative articles separately, then integrated those findings.
 

Navigating through many challenges

The authors found that food allergy lowered the young people’s HRQL. In 11 of the 14 studies (78%) that included a comparison group, young patients with food allergy showed significantly lower HRQL in at least one domain. Most significant differences occurred in domains related to total HRQL (66%), social functioning (58%), emotional functioning (54%), and physical functioning (54%). 

Parents were often more likely than their children to perceive that the child’s food allergy was causing problems.

Between 20% and 32% of children reported bullying related to their food allergy. Many children reported that their allergy sometimes isolated them from their classmates.

Many children described feeling comfortable at home but worried in places where they had less control, such as school, restaurants, or when traveling.

Children and teens tended to downplay their limitations and the negative impacts of their condition.

Older children who had been diagnosed early in life tended to accept managing their food allergy as a way of life, whereas those diagnosed when they were older reported the need to adapt, accept, and grieve the loss of foods and experiences.

“This study highlights the importance of addressing the underlying impact that food allergy can have on patients’ mental health and social functioning,” Kelly Marie O’Shea, MD, assistant professor of allergy and immunology at University of Michigan Health in Ann Arbor, said in an interview.

“While it has been shown previously that food-allergic patients have lower HRQL, this systematic review aptly reveals that for children and teens with food allergy, overall quality of life, including psychosocial functioning, can also be negatively affected,” said Dr. O’Shea, who was not involved in the study.

“Symptoms of anxiety and depression are reported at higher rates in the food-allergic population, and social limitations have been shown to play a role,” she explained. “However, as revealed in this study, longitudinal and appropriately controlled studies to investigate the impact of food allergy on psychosocial outcomes in children and teens are scarce.”

Robert Alan Wood, MD, professor of pediatrics at Johns Hopkins University and director of pediatric allergy and immunology at Johns Hopkins Children’s Center, Baltimore, told this news organization that the effects of food allergy on mental health are not fully appreciated by the public or by many clinicians.

“These findings emphasize the need to recognize the emotional consequences of food allergy and to take steps to be proactive in managing these issues among our patients,” said Dr. Wood, who was not associated with the study.
 

More research is needed

The authors noted that more research is needed to examine links between food allergy, HRQL, and psychosocial outcome; links between food allergy and bullying; and how challenges change over time. They recommend exploring the relative impacts of specific types of food allergy and whether specific traits in young people with food allergy make them more susceptible to its psychological effects. They also call for efforts to identify and help young people with food allergy overcome their many challenges.

The study was funded by the Canadian Institutes for Health Research, the Children’s Hospital Research Institute of Manitoba, and the University of Manitoba.

Study senior author Jennifer L. P. Protudjer, PhD, reported involvement with Canada’s National Food Allergy Action Plan and Allied Health at the Canadian Society of Allergy and Clinical Immunology, and receipt of fees from Novartis. The remaining authors, as well as Dr. O’Shea and Dr. Wood, reported no relevant financial relationships.

Children and COVID-19: Decline in new cases may be leveling off

Article Type
Changed

Even as a number of states see increases in new COVID-19 cases among all ages, the trend remains downward for children, albeit at a slower pace than in recent weeks, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.

New pediatric cases in the United States totaled 27,521 for the most recent week, March 25-31, down by 5.2% from the previous week. Earlier weekly declines, going backward through March and into late February, were 9.3%, 23%, 39.5%, and 46%, according to data collected by the AAP and CHA from state and territorial health agencies. The lowest weekly total recorded since the initial wave in 2020 was just under 8,500 during the week of June 18-24, 2021.

Reported COVID-19 cases in children now total over 12.8 million since the beginning of the pandemic in March 2020, and those infections represent 19.0% of all cases. That share of new cases has not increased in the last 7 weeks, the AAP and CHA noted in their weekly COVID report, suggesting that children have not been bearing a disproportionate share of the declining Omicron burden.

As for Omicron, the BA.2 subvariant now makes up about 55% of COVID-19 infections, the Centers for Disease Control and Prevention said in its COVID Data Tracker Weekly Review, and New York, Massachusetts, and New Jersey are among the states reporting BA.2-driven increases in new cases of as much as 30%, the New York Times said.



Rates of new cases for the latest week available (March 27 to April 2) and at their Omicron peaks in January were 11.3 per 100,000 and 1,011 per 100,000 (ages 0-4 years), 12.5 and 1,505 per 100,000 (5-11 years), 12.7 and 1,779 per 100,000 (12-15 years), and 13.1 and 1,982 per 100,000 (16-17 years), the CDC said on its COVID Data Tracker.

Hospitalization rates, however, were a bit of a mixed bag. The last 2 weeks (March 13-19 and March 20-26) of data available from the CDC’s COVID-NET show that hospitalizations were up slightly in children aged 0-4 years (1.3 per 100,000 to 1.4 per 100,000), down for 5- to 11-year-olds (0.6 to 0.2), and steady for those aged 12-17 (0.4 to 0.4). COVID-NET collects data from nearly 100 counties in 10 states and from a separate four-state network.

Vaccinations got a small boost in the last week, the first one since early February. Initial doses and completions climbed slightly in the 12- to 17-year-olds, while just first doses were up a bit among the 5- to 11-year-olds during the week of March 24-30, compared with the previous week, although both groups are still well below the highest counts recorded so far in 2022, which are, in turn, far short of 2021’s peaks, according to CDC data analyzed by the AAP.

Initial doses and completions climbed slightly in the 12- to 17-year-olds, while just first doses were up a bit among the 5- to 11-year-olds during the week of March 24-30, compared with the previous week, although both groups are still well below the highest counts recorded so far in 2022, which are, in turn, far short of 2021’s peaks, according to CDC data analyzed by the AAP.

Novel drug significantly reduces tics in Tourette syndrome – without side effects

Article Type
Changed

 

An investigational drug that blocks the dopamine-1 (D1) receptor reduces tics and is safe and well tolerated in children with Tourette syndrome, a new study shows.

Importantly, unlike current medications for the disorder, ecocipam does not lead to weight gain, anxiety, depression, or tardive dyskinesia, compared with placebo – a factor that may lead to better adherence.

For clinicians treating children with Tourette syndrome, the results suggest “help is on the way,” said study investigator Donald Gilbert, MD, professor of pediatrics and neurology, University of Cincinnati Children’s Hospital Medical Center.

“There may be a drug available with a new mechanism of action that is effective to suppress tics without causing weight gain or unwanted neuropsychiatric side effects,” Dr. Gilbert said.

The findings will be presented at the 2022 annual meeting of the American Academy of Neurology.
 

First-in-class agent

Tourette syndrome is a neurologic condition that causes sudden repetitive involuntary muscle movements and sounds known as tics. These movements typically develop in childhood and worsen during adolescence.

“There’s a risk of injury, such as to the neck, with tics in childhood, so it’s good to have something that makes tics less severe and less socially impairing in junior high,” said Dr. Gilbert.

While tics generally diminish by adulthood, “about 10% of the patients we see as kids persist into adulthood enough to need medical interventions,” said Dr. Gilbert.

Ecopipam is a first-in-class selective D1 receptor antagonist in clinical development for pediatric patients with Tourette syndrome. The compound was previously tested without success in schizophrenia and in obesity, the idea being that because dopamine is linked to pleasure or reward, blocking it might result in weight loss, said Dr. Gilbert.

However, earlier studies in Tourette syndrome suggested that ecopipam reduces tics in children and adults and had low metabolic and movement-related adverse effects.

Drugs currently used to treat tics include haloperidol, pimocide, and aripiprazole. All of these agents block the dopamine-2 (D2) receptor and can cause weight gain and tardive dyskinesia, said Dr. Gilbert.
 

Placebo-controlled trial

The new study included 149 patients with Tourette syndrome who had a score of at least 20 on the Yale Global Tic Severity Total Tic Score (YGTSS-TTS). The scale measures five aspects of motor and vocal tics: the number, frequency, intensity, complexity, and interference.

With that scale, intensity assesses whether tics cause injury, complexity evaluates the number of muscle group, and interference assesses whether tics interrupt functions, such as speaking or walking.

For each of the five areas, scores range from 0-5, with higher scores indicating greater severity. The motor and vocal parts have a maximum of 25 points each, for a maximum total of 50.

Participants were randomly assigned to receive once-daily oral ecopipam or placebo. A 4-week titration period was followed by an 8-week maintenance period and then a 1-week tapering period.

The primary endpoint was mean change from baseline to week 12 in scores on the YGTSS-TTS.

Results on the YGTSS-TTS showed a significant improvement in the ecopipam group, compared with placebo groups (least square [LS] mean difference: -3.44; 95% confidence interval: -6.09 to -0.79; P = .011).

The analysis indicated a 30% reduction, with an effect size of 0.48, which is “pretty good,” said Dr. Gilbert. “The amount of change is comparable to other drugs that are marketed” to treat tics.

The drug was effective for younger as well as older children. Among those aged 6-11 years, the LS mean difference was -4.95 (95% CI: -9.99 to 0.10; P = .054), and for those aged 12 to 17 years, the LS mean difference was -3.37 (95% CI: -6.51 to -0.24; P = .035).

A key secondary endpoint was the score on the Clinical Global Impression of Tourette Syndrome Severity, which Dr. Gilbert said is a more subjective measure of whether a patient’s life has improved. Here, the mean change at week 12 was significant (P = .001) for the treated group (improvement of 0.91 points), compared with the placebo group (improvement of 0.5 points).

Researchers also assessed safety and tolerability. Treatment-related adverse events (AEs) occurred in 34% of patients taking ecopipam and in 21% of those taking placebo. The most common AEs were headache (9.2%), fatigue (6.6%), somnolence (6.6%), and restlessness (5.3%).

There were no metabolic or movement-related AEs or treatment-related serious AEs.

“This drug doesn’t cause weight gain at all,” said Dr. Gilbert. He noted that there was also no difference in the groups in terms of rates of depression, anxiety, or tardive dyskinesia.
 

 

 

Significant tic reduction

Commenting on the findings, Jessica Frey, MD, a movement disorders fellow at the University of Florida, said the new double-blind, placebo-controlled study “is promising” in that it demonstrates significant tic reduction, compared with placebo without significant side effects.

“Ecopipam could potentially expand pharmacologic treatment options for children and adolescents with Tourette syndrome in the near future,” she said.

Dr. Frey will also be presenting results at the meeting of a study showing a significant correlation between tic severity and social media use among adolescents with Tourette syndrome during the COVID pandemic.

She noted that dopamine is an important neurotransmitter in the underlying pathophysiology of Tourette syndrome. In addition, although D2 receptor blockade can provide significant tic reduction, the “intolerable” side effects often linked to medications with this mechanism “can lead to discontinuation,” said Dr. Frey.

She also noted that ecopipam has previously been evaluated in an open-label study and a follow-up placebo-controlled study that demonstrated safety as well as significant tic reduction.

The study was supported by Emalex Biosciences. Dr. Gilbert and Dr. Frey report no relevant financial relationships.
