Chinese American families suffer discrimination related to COVID-19
according to results from a survey study.
In the United States, where public officials continue to refer to SARS-CoV-2 as the “China virus” and have often sought to draw attention to its origins in Wuhan, China, “the associations between discrimination triggered by the racialization of this acute public health crisis and mental health are unknown,” Charissa S.L. Cheah, PhD, of the University of Maryland, Baltimore County, and colleagues wrote.
For their research published Oct. 29 in Pediatrics, Dr. Cheah and colleagues recruited a cohort of 543 Chinese American parents of school-age children, and 230 of their children aged 10-18 years, to complete online surveys between mid-March and late May 2020. Parents in the cohort were largely foreign born, with all identifying as ethnically Chinese, while their children were mostly U.S. born.
Evidence of discrimination against Chinese Americans
Half of parents and their children (51% of parents and 50% of youth) reported experiencing at least one in-person incident of direct discrimination (assessed using questions derived from a validated scale of racial aggression) related to the pandemic. Dr. Cheah and colleagues also reported a high incidence of direct discrimination online (32% of parents and 46% of youth). Additionally, the researchers measured reports of vicarious or indirect discrimination – such as hearing jokes or disparaging remarks about one’s ethnic group – which they used a different adapted scale to capture. More than three-quarters of the cohort reported such experiences.
The experiences of discrimination likely bore on the mental health of both parents and youth. Using a series of instruments designed to measure overall psychological well-being as well as symptoms of depression, anxiety, and certain emotional and behavioral outcomes, Dr. Cheah and colleagues reported significant negative associations between direct online or in-person discrimination and psychological health. For parents and children alike, anxiety and depressive symptoms were positively associated with all varieties of discrimination experiences measured in the study.
About a fifth of the youth in the study were deemed, based on the symptom scales used in the study, to have an elevated risk of clinically significant mental health problems, higher than the 10%-15% that would be expected for these age groups in the United States.
“This study revealed that a high percentage of Chinese American parents and their children personally experienced or witnessed anti-Chinese or anti–Asian American racial discrimination both online and in person due to the COVID-19 pandemic,” the investigators wrote. “Most respondents reported directly experiencing or witnessing racial discrimination against other Chinese or Asian American individuals due to COVID-19 at least once.”
Dr. Cheah and colleagues noted that their cross-sectional study did not lend itself to causal interpretations and was vulnerable to certain types of reporting bias. Nonetheless, they argued, as the pandemic continues, “pediatricians should be sensitive to the potential mental health needs of Chinese American youth and their parents related to various forms of racism, in addition to other stressors, as the foundations of perceptions of racial-ethnic discrimination and their consequences may be set during this period.”
COVID-19 didn’t only bring infection
In an accompanying editorial, Tina L. Cheng, MD, of Johns Hopkins University, Baltimore, and her daughter Alison M. Conca-Cheng, a medical student at Brown University, Providence, R.I., remarked that the study’s findings were consistent with recent research that found “4 in 10 Americans reported that it has become more common since COVID-19 for people to express racist views about Asian Americans,” and also described an increase in complaints of discriminatory experiences by Asian Americans.
In this context, a link to poor mental health “should be no surprise,” Dr. Cheng and Ms. Conca-Cheng argued, and urged pediatricians to consult the American Academy of Pediatrics’ 2019 policy statement on racism and on child and adolescent health. “It calls for us to optimize clinical practice, improve workforce development and professional education, strengthen research, and deploy systems through community engagement, advocacy, and public policy.”
David Rettew, MD, a child and adolescent psychiatrist and associate professor of psychiatry and pediatrics at the University of Vermont, Burlington, called the study’s main points “clear and disturbing.”
“While it is difficult to find much in the way here of a silver lining, these alarming reports have helped people working in health care and mental health to understand racism as another form of trauma and abuse which, like other types, can have real negative effects on health,” Dr. Rettew said in an interview. “The more we as mental health professions ask about racism and offer resources for people who have experienced it, just as we would people who have endured other types of trauma, the more we can help people heal. That said, it would be better just to stop this from happening in the first place.”
Dr. Cheah and colleagues’ study was supported by a National Science Foundation grant. The investigators disclosed no conflicts of interest. Dr. Cheng and Ms. Conca-Cheng disclosed no financial conflicts of interest related to their editorial. Dr. Rettew said he had no relevant financial disclosures.

ODC1 gene linked to newly described neurodevelopmental disorder
but it may be treated with diet modifications and available therapies, according to the researcher whose group first identified the disorder.
Lance Rodan, MD, of Boston Children’s Hospital and Harvard Medical School, reported on research into ODC1 gain-of-function disorder –named for ornithine decarboxylase 1, the rate-limiting enzyme involved in polyamine synthesis – in the Linda De Meirleir Neurometabolic award lecture at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year. Dr. Rodan and colleagues first described ODC1 disorder in a multicenter case series.
Dr. Rodan noted that dysregulated polyamine levels are associated with cancer, and that ODC1 is expressed “ubiquitously” throughout the body.
Pathophysiology and phenotypes
In an interview, he described the metabolic process more fully. “GI flora can produce putrescine, which is the polyamine that accumulates in excess in the ODC1 gain-of-function disorder. It is yet to be elucidated if decreasing putrescine production by GI flora and/or reducing dietary sources of putrescine may play a role in the management of this disorder.”
In the De Meirleir lecture, Dr. Rodan described four patients from his group’s published case series, all found to have heterozygous de novo variants in the ODC1 gene, along with a fifth patient reported by Caleb Bupp, MD, and colleagues at Michigan State University, East Lansing.
“There’s a recognizable phenotype to this disorder,” Dr. Rodan said. “These individuals have neurodevelopment abnormalities. They may have behavioral concerns. They have low-tone central hypertonia and macrocephaly.”
One of the most distinctive characteristics of ODC1 disorder is alopecia, he said, “which in almost everybody with this condition involves the eyebrows and eyelashes and in some individuals also involves the scalp hair.”
These patients also have what Dr. Rodan called “a common yet subtle facial gestalt.” That can include hypertelorism, spareness of the eyebrows and eyelashes, and a tubular- shaped nose with a short columella and a short philtrum.
They may also have abnormalities of the nails and cryptorchidism, and typically a prenatal history of polyhydramnios, he said.
MRI findings include prominent perivascular spaces, periventricular cysts, abnormal white matter and corpus callosum abnormalities, he said, adding that the fetal case MRI demonstrated subepidermal cysts, white matter cysts in the temporal pole, deficiency of the falx cerebri and abnormal white-matter signals.
Biochemical features of ODC1 disorder include increased N-acetylputrescine levels with normal spermine and spermidine levels, Dr. Rodan said. He also noted that Dr. Bupp’s group reported increased putrescine in fibroblasts and increased ODC1 protein levels in red blood cells.
Dr. Rodan also described possible molecular mechanisms in ODC1 disorder. One was the location of the ODC1 variants: all were reported closely located to truncating variants in the final exon of the ODC1 gene. This allows truncating proteins to survive, adding to the degradation that results in a net gain-of-function of ODC1 enzyme activity.
With regard to pathophysiology of ODC1 disorder, Dr. Rodan noted that research has implicated chronically elevated putrescine levels in the alopecia, a finding animal models support. “Since putrescine is a precursor for gamma-aminobutyric acid, it’s possible perturbed GABA levels may also be involved,” he said. Abnormal modulation N-methyl-D-aspirate receptors may also be involved, he said.
Another hypothesis purports that potential of elevated levels of toxic aldehydes/H2O2 similar to Snyder-Robinson syndrome, the better known polyamine-related neurometabolic disorder. “Along those lines, maybe there’s also a secondary mitochondrial or lysosomal dysfunction, but this is something that’s still being actively studied,” Dr. Rodan said.
Treatment
Because ODC1 disorder was only first described 2 years ago, research into treatment is nascent. “In terms of management, I think one of the more fundamental questions is whether this is more of a static developmental disorder or whether this actually represents a progressive degenerative disorder,” Dr. Rodan said.
One potential treatment that has been explored, he said, is difluoromethylornithine, a synthetic ODC1 inhibitor already Food and Drug Administration approved for African sleeping sickness and as a topical treatment for hirsutism. It is also the subject of ongoing clinical trials in colon cancer and neuroblastoma. Potential side effects include myelosuppression, seizures and hearing loss.
Dr. Rodan noted that a single-center study reported that difluoromethylornithine in a 3-year-old patient with ODC1 disorder reduced ODC protein activity and putrescine to control levels.
Other potential treatments include the natural ODC1 inhibitors agmatine and turmeric/curcumin, flagyl/rifaximin to decrease putrescine production in the gut, a low-dairy diet to lower putrescine levels, and antioxidants. “There could be a role for antioxidant stress similar to what is seen in Snyder-Robinson syndrome,” Dr. Rodan said.
Based on mouse studies, patients with ODC1 may be at risk of skin cancer, so regular skin checks along with sun protection should be part of management, he said. “This also raises the question of whether there should be surveillance for other types of cancer given the role of polyamine in various types of tumors.”
Dr. Rodan has no relevant financial relationships to disclose.

Decide ADHD pharmacotherapy based on medication onset, duration of action
Clinicians have numerous pharmacotherapy options available to treat ADHD in their toolbox. How do you know which formulation or combination of therapies is right for your patient with ADHD?
According to Jeffrey R. Strawn, MD, the answer depends on onset and duration of the medication and how that fits in to the patient’s current needs.
The most common treatment for ADHD, stimulants, are amphetamine-based and methylphenidate-based compounds known for improving core symptoms of inattention, impulsivity, and hyperactivity and are “probably associated with the most efficacy relative to the other interventions,” Dr. Strawn, associate professor of psychiatry, pediatrics, and clinical pharmacology at Cincinnati Children’s Hospital Medical Center, said at Psychopharmacology Update presented by Current Psychiatry and Global Academy for Medical Education. “But what I think is also really important for us to remember as clinicians is that they improve adherence, social interactions, [and] academic efficiency as well as accuracy.”
Other ADHD pharmacotherapy options include nonstimulant norepinephrine reuptake inhibitors (NRIs) like atomoxetine, and alpha-2 agonists like the extended-release forms of guanfacine and clonidine. All are Food and Drug Administration–approved for the treatment of ADHD, and the FDA has approved some combination alpha-2 agonists and stimulants treatments for ADHD as well.
When making decisions about formulations for ADHD pharmacotherapy, clinicians should think about whether the patient has issues swallowing tablets or capsules. Tablets, capsules, and chewable tablets may be appropriate for patients who can easily take these medications, while patients who have problems with swallowing pills may benefit from dissolvable tablets, solutions, and transdermal applications. Each of these options “have differences in terms of absorption, also differences in terms of intestinal transit time in younger children, as well as patients perhaps with irritable bowel, as well as other conditions that may affect absorption,” Dr. Strawn said. Different formulations have unique considerations: liquid formulations have the benefit of making precise adjustments, sublingual formulations may have quick absorption and onset, and oral dissolvable tablets can improve treatment adherence and reduce misuse of medication.
Formulations can be available as a delayed release, extended release, pulsatile release, targeted release, or a combination of immediate, delayed, and/or extended release. “Ultimately, what this gives rise to is differences in onset of action and duration, as well as differences in the elimination profile of the medication,” he said.
Transdermal formulations “avoid the first-pass metabolism, which may reduce side effects or increase efficacy,” but patients converting from an oral formulation may require reducing the dose. “It’s always important to remember, for example, with something like Daytrana, the transdermal methylphenidate formulation, if we’re converting a patient from an oral methylphenidate, we roughly need to use half the dose for the transdermal formulation,” Dr. Strawn explained. Transdermal formulations can carry benefits of steady plasma concentrations and longer duration of action but may cause skin irritation or accidentally be removed. “It’s really important they’re properly disposed of because oftentimes they do contain some active medication within the residual matrix.”
Methylphenidate, mixed amphetamine salt–based preparations
Modified-release formulations include matrix- or reservoir-based formulations and are most importantly differentiated from other formulations by their gastrointestinal (GI) transit time and the permeation through the GI membrane. When considering what formulation to choose, “it’s important to consider that, even with an ‘extended release formulation,’ all of these medications have some percentage that is immediately released, and that percentage varies considerably from formulation to formulation,” Dr. Strawn said.
He noted that brand names are sometimes used for formulations “because it’s often very difficult for us as clinicians and even for pharmacists to distinguish between these various formulations of the medication, which often have the same ‘extended’ or ‘delayed release’ modifying term within the name of the medication.”
Examples of medications that have greater immediate release include Metadate CD (30%), Aptensio XR (37%), long-acting methylphenidate (50%), dexmethylphenidate extended-release (50%), and Mixed Salts amphetamine extended release (50%). Formulations with a less immediate release include Quillivant solution or Quillichew chewable tablets (20%), Dyanaval XR solution (20%), OROS methylphenidate (22%), Daytrana that begins within 1 or 2 hours and lasts for 9 hours, or lisdexamfetamine that begins within 1 hour and lasts for 9 hours.
Depending on a patient’s needs, one particular formulation may work better than another. Dexmethylphenidate (Focalin XR) has a 50% immediate release and 50% extended release formulation, which “may be really important for a high school student who has first period precalculus followed by second period human geography,” Dr. Strawn said, while “a patient who may have first period study hall and second period art” may benefit from OROS methylphenidate.
Clinicians should also consider the effect of counterclockwise hysteresis when adding a short-acting stimulant later in the day. “There seems to be something really magic about having that ascending concentration time curve that, when we’re on the descending loop of that concentration time curve, we really seem to get a dramatic waning of the effect of the medication, even though technically the concentration is within the ‘therapeutic range,’ ” Dr. Strawn said. “With counterclockwise hysteresis, we see that the effect increases with time for a given concentration of the medication.”
Combining ADHD pharmacotherapies
For children and adolescents with ADHD, atomoxetine is a nonstimulant, FDA-approved treatment option. “It seems to be effective not just in terms of total ADHD symptoms, but also in terms of hyperactive and impulsive symptoms as well as the inattentive symptoms,” Dr. Strawn said.
Pharmacogenetics can be a guide for selecting an atomoxetine for a patient with ADHD, he noted. “What I think is most relevant here is the way in which pharmacogenetics can actually help guide our dosing, which then optimizes tolerability, potentially efficacy of atomoxetine,” he said. “Atomoxetine is pretty extensively metabolized by [CYP]2D6, and it’s one of about 300 medications that actually has specific labeling from the FDA on dosing based on genotype. It recommends a slower titration, as well as a lower target dose of atomoxetine in individuals who are P450 2D6 poor metabolizers relative to those patients who are ultra-rapid or normal metabolizers.”
Atomoxetine is most often combined with methylphenidate and has some evidence of benefit in children or adolescents who do not have an adequate response to stimulants alone. When combining stimulants with the alpha-2 agonists guanfacine or clonidine, “there are some improvements in terms of the combination treatment relative to the monotherapy,” Dr. Strawn said. He also emphasized that patients taking guanfacine immediate release tend to have better absorption and faster onset, compared with the extended release formulation. “This is something that potentially is very important when we think beyond steady state and we think about the practical use of this medication,” he said.
Baseline history is important
Overall, taking a baseline history of a patient with ADHD is “critically important” before starting them on stimulants, Dr. Strawn said. “Specifically, I would recommend documenting a negative history of syncope, family history of sudden cardiac death, as well as the lack of any known history of structural cardiac abnormalities,” he said. “Without a consultation with the cardiologist specifically around this question, I’m very, very, very hesitant – as in I don’t – use stimulants in patients who have histories of aortic stenosis, Wolff-Parkinson-White, as well as arrhythmogenic right ventricular dysplasia.”
Although patients with ADHD were typically followed with routine hemodynamic monitoring every 3 months prior to the COVID-19 pandemic, some clinicians see their patients with ADHD less frequently if they have been stabilized on a stimulant. , particularly in young children. In adults, it may also be very helpful to talk with spouses,” Dr. Strawn said.
Dr. Strawn also called attention to a recommendation to perform a routine electrocardiogram (EKG) in patients with ADHD who might receive stimulants. “At present, there is no recommendation to obtain a routine screening EKG in these patients, provided that we have an absence of those other red flags on the history,” he said. “Certainly, I would consider it in situations where I do have persistent tachycardia or hypertension, or there are other treatment-emergent symptoms, although really in many of these situations, I’m actually speaking on the phone with my pediatric or adult cardiology colleagues.”

Clinicians have numerous pharmacotherapy options available to treat ADHD in their toolbox. How do you know which formulation or combination of therapies is right for your patient with ADHD?
According to Jeffrey R. Strawn, MD, the answer depends on onset and duration of the medication and how that fits in to the patient’s current needs.
The most common treatment for ADHD, stimulants, are amphetamine-based and methylphenidate-based compounds known for improving core symptoms of inattention, impulsivity, and hyperactivity and are “probably associated with the most efficacy relative to the other interventions,” Dr. Strawn, associate professor of psychiatry, pediatrics, and clinical pharmacology at Cincinnati Children’s Hospital Medical Center, said at Psychopharmacology Update presented by Current Psychiatry and Global Academy for Medical Education. “But what I think is also really important for us to remember as clinicians is that they improve adherence, social interactions, [and] academic efficiency as well as accuracy.”
Other ADHD pharmacotherapy options include nonstimulant norepinephrine reuptake inhibitors (NRIs) like atomoxetine, and alpha-2 agonists like the extended-release forms of guanfacine and clonidine. All are Food and Drug Administration–approved for the treatment of ADHD, and the FDA has approved some combination alpha-2 agonists and stimulants treatments for ADHD as well.
When making decisions about formulations for ADHD pharmacotherapy, clinicians should think about whether the patient has issues swallowing tablets or capsules. Tablets, capsules, and chewable tablets may be appropriate for patients who can easily take these medications, while patients who have problems with swallowing pills may benefit from dissolvable tablets, solutions, and transdermal applications. Each of these options “have differences in terms of absorption, also differences in terms of intestinal transit time in younger children, as well as patients perhaps with irritable bowel, as well as other conditions that may affect absorption,” Dr. Strawn said. Different formulations have unique considerations: liquid formulations have the benefit of making precise adjustments, sublingual formulations may have quick absorption and onset, and oral dissolvable tablets can improve treatment adherence and reduce misuse of medication.
Formulations can be available as a delayed release, extended release, pulsatile release, targeted release, or a combination of immediate, delayed, and/or extended release. “Ultimately, what this gives rise to is differences in onset of action and duration, as well as differences in the elimination profile of the medication,” he said.
Transdermal formulations “avoid the first-pass metabolism, which may reduce side effects or increase efficacy,” but patients converting from an oral formulation may require reducing the dose. “It’s always important to remember, for example, with something like Daytrana, the transdermal methylphenidate formulation, if we’re converting a patient from an oral methylphenidate, we roughly need to use half the dose for the transdermal formulation,” Dr. Strawn explained. Transdermal formulations can carry benefits of steady plasma concentrations and longer duration of action but may cause skin irritation or accidentally be removed. “It’s really important they’re properly disposed of because oftentimes they do contain some active medication within the residual matrix.”
Methylphenidate, mixed amphetamine salt–based preparations
Modified-release formulations include matrix- or reservoir-based formulations and are most importantly differentiated from other formulations by their gastrointestinal (GI) transit time and the permeation through the GI membrane. When considering what formulation to choose, “it’s important to consider that, even with an ‘extended release formulation,’ all of these medications have some percentage that is immediately released, and that percentage varies considerably from formulation to formulation,” Dr. Strawn said.
He noted that brand names are sometimes used for formulations “because it’s often very difficult for us as clinicians and even for pharmacists to distinguish between these various formulations of the medication, which often have the same ‘extended’ or ‘delayed release’ modifying term within the name of the medication.”
Examples of medications that have greater immediate release include Metadate CD (30%), Aptensio XR (37%), long-acting methylphenidate (50%), dexmethylphenidate extended-release (50%), and Mixed Salts amphetamine extended release (50%). Formulations with a less immediate release include Quillivant solution or Quillichew chewable tablets (20%), Dyanaval XR solution (20%), OROS methylphenidate (22%), Daytrana that begins within 1 or 2 hours and lasts for 9 hours, or lisdexamfetamine that begins within 1 hour and lasts for 9 hours.

FROM PSYCHOPHARMACOLOGY UPDATE
The new one-percenters: Children with COVID-19
according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.
There have been 1,052 cases of COVID-19 per 100,000 children as of Oct. 22, and that works out to 1.05% of all children in the country. The cumulative number of pediatric cases is 792,188, and children now represent 11% of all COVID-19 cases, the AAP and the CHA reported Oct. 26.
There were just over 50,000 new child cases reported in the week ending Oct. 22, which was 13.6% of the national total of almost 370,000. That’s up slightly from the 13.3% the previous week but still down from the spike seen in mid-September, based on the data collected from the websites of 49 state health departments (New York does not report ages), along with the District of Columbia, New York City, Puerto Rico, and Guam.
The state-level data show that California has had more COVID-19 cases in children (92,864) than any other state, although Texas has reported ages for only 7% of its confirmed cases. Illinois is next with 46,006 cases, followed by Florida at 45,575, although Florida is using an age range of 0-14 years to define a child case, the AAP and CHA noted.
Other measures largely put small states at the extremes:
- North Dakota has the highest cumulative rate: 2,954 cases per 100,000 children.
- Vermont has the lowest cumulative rate: 190.5 per 100,000.
- Wyoming has the highest proportion of cases in children: 27.7%.
- New Jersey has the lowest proportion of child cases: 4.6%.
There were no COVID-19–related deaths in children reported the week ending Oct. 22, so the total number remains at 120, which is just 0.06% of the total for all ages, based on data from 42 states and New York City. Hospitalization figures put admissions at almost 5,600 in children, or 1.7% of all hospitalizations, although those data come from just 24 states and New York City, the AAP and CHA said.

Ataluren delays disease milestones in patients with nonsense mutation DMD
(nmDMD), according to study results presented at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year. Because so few patients in the study reached one of the negative pulmonary endpoints, longer follow-up will be needed to assess more conclusively the effect of ataluren on pulmonary function, said Francesco Bibbiani, MD, vice president of clinical development at PTC Therapeutics.
DMD is a rare and fatal neuromuscular disorder that causes progressive muscle weakness. Between 10% and 15% of patients with DMD have a nonsense mutation in the DMD gene. This mutation creates a premature stop codon that prevents the translation of a full-length dystrophin protein. Ataluren is designed to promote readthrough of this premature stop codon, thus enabling the production of a full-length dystrophin protein. An oral formulation of the drug has been approved in several European and South American countries.
Comparing treatment and standard of care
Study 019 was a phase 3, multicenter, open-label, long-term safety study of ataluren that enrolled international patients with nmDMD, most of whom had participated previously in a trial of ataluren. Dr. Bibbiani and colleagues conducted a post hoc analysis of Study 019 data to determine whether patients with nmDMD who received ataluren and standard of care for as long as 240 weeks had a different time to loss of ambulation and to decline of pulmonary function, compared with patients who received standard of care alone. Patients who were eligible to participate in Study 019 were male, had nmDMD, and had completed the blinded study drug treatment in a previous PTC-sponsored study. Treatment consisted of two 10-mg/kg doses and one 20-mg/kg dose of ataluren per day.
Dr. Bibbiani and colleagues used participants in the Cooperative International Neuromuscular Research Group Duchenne Natural History Study (CINRG DNHS) as a control group. CINRG DNHS was a prospective, longitudinal study of patients with DMD who received standard of care at 20 centers worldwide from 2006 to 2016. Dr. Bibbiani and colleagues used propensity-score matching to pair participants in this study with participants in Study 019. They matched patients with respect to age at onset of first symptoms, age at initiation of corticosteroid use, duration of deflazacort use, and duration of use of other corticosteroids. These factors are established predictors of disease progression in DMD.
Patients were eligible for inclusion in the post hoc analysis if they had available data for age, loss of ambulation, and the covariates selected for matching. Of 94 Study 019 participants, 60 were eligible for propensity-score matching with participants in CINRG DNHS. Forty-five nonambulatory patients were eligible for matching in the analysis of age at the decline in pulmonary function because data for age at loss of ambulation and for the three pulmonary endpoints measured were available for them. Thus, comparable population sizes were available for each analysis.
Treatment delayed disease milestones
Kaplan–Meier analysis indicated that the median age at various disease milestones was higher among patients who received ataluren and standard of care, compared with those who received standard of care alone. The median age at loss of ambulation was 15.5 years for Study 019 participants and 13.3 years for CINRG DNHS patients. The median age at predicted forced vital capacity (FVC) of less than 60% was 18.1 years for Study 019 participants and 15.8 years for CINRG DNHS participants. The median age at predicted FVC of less than 50% was 19.1 years for Study 019 participants and 17.9 years for CINRG DNHS participants. Finally, the median age at FVC of less than 1 L was not calculable for Study 019 participants and 23.8 years for CINRG DNHS participants.
The Study 019 and CINRG DNHS study groups are sponsored by PTC Therapeutics, which developed ataluren. Dr. Bibbiani is an employee of PTC Therapeutics.

Dr. Bibbiani and colleagues used propensity-score matching to pair participants in this study with participants in Study 019. They matched patients with respect to age at onset of first symptoms, age at initiation of corticosteroid use, duration of deflazacort use, and duration of use of other corticosteroids. These factors are established predictors of disease progression in DMD.
Patients were eligible for inclusion in the post hoc analysis if they had available data for age, loss of ambulation, and the covariates selected for matching. Of 94 Study 019 participants, 60 were eligible for propensity-score matching with participants in CINRG DNHS. Forty-five nonambulatory patients were eligible for matching in the analysis of age at the decline in pulmonary function because data for age at loss of ambulation and for the three pulmonary endpoints measured were available for them. Thus, comparable population sizes were available for each analysis.
Treatment delayed disease milestones
Kaplan–Meier analysis indicated that the median age at various disease milestones was higher among patients who received ataluren and standard of care, compared with those who received standard of care alone. The median age at loss of ambulation was 15.5 years for Study 019 participants and 13.3 years for CINRG DNHS patients. The median age at predicted forced vital capacity (FVC) of less than 60% was 18.1 years for Study 019 participants and 15.8 years for CINRG DNHS participants. The median age at predicted FVC of less than 50% was 19.1 years for Study 019 participants and 17.9 years for CINRG DNHS participants. Finally, the median age at FVC of less than 1 L was not calculable for Study 019 participants and 23.8 years for CINRG DNHS participants.

(nmDMD), according to study results presented at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year. Because so few patients in the study reached one of the negative pulmonary endpoints, longer follow-up will be needed to assess more conclusively the effect of ataluren on pulmonary function, said Francesco Bibbiani, MD, vice president of clinical development at PTC Therapeutics.
DMD is a rare and fatal neuromuscular disorder that causes progressive muscle weakness. Between 10% and 15% of patients with DMD have a nonsense mutation in the DMD gene. This mutation creates a premature stop codon that prevents the translation of a full-length dystrophin protein. Ataluren is designed to promote readthrough of this premature stop codon, thus enabling the production of a full-length dystrophin protein. An oral formulation of the drug has been approved in several European and South American countries.
Comparing treatment and standard of care
Study 019 was a phase 3, multicenter, open-label, long-term safety study of ataluren that enrolled international patients with nmDMD, most of whom had participated previously in a trial of ataluren. Dr. Bibbiani and colleagues conducted a post hoc analysis of Study 019 data to determine whether patients with nmDMD who received ataluren and standard of care for as long as 240 weeks had a different time to loss of ambulation and to decline of pulmonary function, compared with patients who received standard of care alone. Patients who were eligible to participate in Study 019 were male, had nmDMD, and had completed the blinded study drug treatment in a previous PTC-sponsored study. Treatment consisted of two 10-mg/kg doses and one 20-mg/kg dose of ataluren per day.

Newer DMTs are more effective than injectable DMTs in pediatric MS
Nevertheless, all DMTs reduce children’s annualized relapse rate (ARR), according to results presented at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year.
“Our study adds weight to the argument for an imminent shift in clinical practice toward the use of newer, more efficacious DMTs in the first instance,” said Omar Abdel-Mannan, MD, of Great Ormond Street Hospital in London. MRI activity continues among patients treated with DMTs, and the number of relapses is highest in the period following diagnosis. But because the effect of treatment on brain atrophy is greatest in the initial period of disease, “this time period may represent a critical therapeutic window for the use of highly effective therapies,” said Dr. Abdel-Mannan.
An examination of medical records
MS is much less prevalent among children than among adults. Compared with adults with MS, children with MS have a higher relapse rate and slower accumulation of disability. The individual response to DMTs is variable, said Dr. Abdel-Mannan. Furthermore, current standards of care for pediatric MS vary by center and are based on adult protocols.
Dr. Abdel-Mannan and colleagues conducted a retrospective study to evaluate the real-world effectiveness of the newer oral and infusion DMTs, compared with the older injectable DMTs, in children with relapsing-remitting MS. They examined data from seven tertiary pediatric neurology centers in the United Kingdom and identified patients under age 18 years with relapsing-remitting MS who were treated with DMTs between 2012 and 2018. The investigators reviewed clinical and paraclinical data retrospectively using electronic medical records. They compared patients’ ARR, new radiological activity, and Expanded Disability Status Scale score pretreatment and on treatment.
The researchers included 103 patients in their analysis. The population’s median age was 14 years. The ratio of girls to boys was approximately 3:1. Whites and other races/ethnicities accounted for approximately equal groups of patients. About one-third of patients presented with a clinically isolated syndrome (CIS) in the form of transverse myelitis or optic neuritis. Two-thirds presented with other CIS phenotypes. Almost all children had an abnormal MRI at onset.
Most patients initiated injectable DMTs
Of the 103 patients, 89 started treatment with an injectable (e.g., glatiramer or interferon) or an older DMT. Fourteen patients began treatment with a newer DMT (e.g., dimethyl fumarate, fingolimod, natalizumab, and alemtuzumab). Three of the 89 patients on an injectable DMT switched to another injectable DMT, and two of these patients later escalated to a newer DMT. Thirty-five of the 89 patients who initiated an injectable DMT were escalated immediately to a newer DMT. One of these patients later switched to another newer DMT. Two of the 14 patients who started on a newer DMT as their first drug switched to another newer DMT.
The investigators observed a reduction in ARR for all DMTs used during the study period. Nevertheless, a significant number of patients receiving injectable DMTs continued to relapse on treatment. Almost all patients receiving newer DMTs, however, had a reduction in relapses. When Dr. Abdel-Mannan and colleagues performed Kaplan–Meier survival analysis, they found that patients receiving newer DMTs had a longer time to first relapse and a longer time to switch treatment over 2 years, compared with patients receiving injectable DMTs. In addition, patients receiving newer DMTs had a longer time to develop new radiological activity, compared with patients receiving injectables. The analysis also indicated that the proportion of patients with new radiological activity was higher than the proportion who had clinical relapses and an Expanded Disability Status Scale score increase of more than 1 point over 2 years.
In all, 55 of the children receiving injectable DMTs and 18 of the patients receiving newer DMTs had side effects. The most commonly reported side effects were flulike symptoms and injection-site reactions. Five patients discontinued or switched their DMTs because of side effects. “Reassuringly, no pediatric-specific side effects were reported,” said Dr. Abdel-Mannan. The newer DMTs had similar short-term safety, tolerability, and side-effect profiles in these children as in adult patients.
The study was conducted on behalf of the UK Childhood Inflammatory Demyelination Network. Dr. Abdel-Mannan had no relevant disclosures.

Study supports halting antiseizure medications after neonatal seizures
Maintaining antiseizure medication in infants who have had acute symptomatic neonatal seizures has been standard practice, but a prospective, observational, comparative effectiveness study calls that practice into question, providing evidence that discontinuing therapy at discharge poses no harm to children and has no effect on the development of epilepsies.
“,” said Hannah C. Glass, MDCM, MAS, of the University of California, San Francisco, Benioff Children’s Hospital, co-principal investigator, who presented results of the study at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year. Renee Shellhaas, MD, MS, clinical associate professor of pediatrics at C.S. Mott Children’s Hospital, University of Michigan, was the other co-principal investigator.
“Although other, smaller studies have suggested it is safe to discontinue antiseizure medication after resolution of acute symptomatic seizures, the practice of early discontinuation has been very variable and depends largely on individual provider preference,” Dr. Glass said in an interview. “In our study, two-thirds of newborns with acute symptomatic seizures were maintained on antiseizure medication at the time of hospital discharge. Thus, a change to early medication discontinuation represents a major shift.”
The study evaluated 270 infants at nine centers enrolled in the Neonatal Seizure Registry and born from July 2015 through March 2018. Inclusion criteria were acute symptomatic seizures that occurred at up to 44 weeks postmenstrual age. In this cohort, 36% of patients had antiseizure medication discontinued after a median of 6 days; the remainder stayed on antiseizure medication after discharge at a median of 4 months.
The patients were followed for 2 years. The primary outcome was functional development measured by the Warner Initial Development Evaluation of Adaptive and Functional Skills (WIDEA-FS) assessment. The secondary outcome was epilepsy defined by International League Against Epilepsy (ILAE) criteria. Follow-up consisted of phone calls and chart reviews at 12, 18, and 24 months.
“The primary outcome, functional development, was not significantly different between those children who were maintained on antiseizure medication as compared with those who were discontinued,” Dr. Glass said.
After propensity adjustment, the discontinued ASM group had an estimated WIDEA-FS score 4 points higher on average, she said. “The confidence intervals met our a priori noninferiority limit, indicating no harm to neurodevelopment for discontinuing antiseizure medication before discharge home from the neonatal seizure admission,” Dr. Glass noted.
The study also found that 13% of all participants developed epilepsy at a median of 8 months. “There was no significant difference in the frequency or timing of epilepsy between the two groups,” she said.
“We conclude there is no clear rationale for antiseizure medication maintenance,” Dr. Glass said. “There is no benefit to neurodevelopment, it prolongs the exposure to potentially harmful antiseizure medications, it does not significantly delay the onset of epilepsy, and the earliest-onset epilepsies occur in spite of antiseizure medication.”
The Patient-Centered Outcomes Research Institute (PCORI) and Pediatric Epilepsy Research Foundation funded the study. Dr. Glass has no other financial relationships to disclose.

JIA arthritis and uveitis flares ‘often run parallel’
Children with juvenile idiopathic arthritis–associated uveitis (JIA-U) are significantly more likely to experience a flare in their eye disease if their arthritis is also worsening, a team of U.S.-based researchers has found.
In a longitudinal cohort study, children with active arthritis at the time of a routine rheumatology assessment had an almost 2.5-fold increased risk of also having active uveitis 45 days before or after the assessment than did children whose arthritis was not flaring at the rheumatology assessment.
“We demonstrate that the two diseases often run parallel courses,” corresponding author Emily J. Liebling, MD, of the Children’s Hospital of Philadelphia and associates state in Arthritis Care & Research, noting that the magnitude of the association is striking.
“Although there are known risk factors associated with uveitis development in children with JIA, less data are available about factors associated with uveitis flare or activity,” said Sheila T. Angeles-Han, MD, MSc, of the departments of pediatrics and ophthalmology at Cincinnati Children’s Hospital Medical Center who commented on the study in an interview.
“If proven, this knowledge has the potential to impact practice patterns and current guidelines wherein a pediatric rheumatologist who evaluates a child with JIA-associated uveitis and finds active arthritis would request an expedited ophthalmic examination,” Dr. Angeles-Han suggested.
Dr. Angeles-Han led the development of the first American College of Rheumatology/Arthritis Foundation Guideline for the Screening, Monitoring, and Treatment of JIA-Associated Uveitis, which recommends regular screening for uveitis in all children with JIA. Children found to have uveitis should then be screened at least every 3 months, and more frequently if they are taking glucocorticoids and treatment is being tapered.
JIA-associated uveitis accounts for around 20%-40% of all cases of noninfectious childhood eye inflammation, and it can run an insidious and chronic course.
“Children with acute anterior uveitis are symptomatic and tend to have a painful red eye, thus prompting an ophthalmic evaluation,” Dr. Angeles-Han explained. “This is different from children with chronic anterior uveitis who tend not to have any symptoms, thus a screening examination is critical to detect ocular inflammation.”
While the ACR/AF guideline distinguishes between acute and chronic uveitis, Dr. Liebling and colleagues explain that they did not because their experience shows that “even patients with chronic anterior uveitis, typically thought to have silent disease, may exhibit symptoms of eye pain, redness, vision changes, and photophobia.”
Conversely, they say “the JIA subtypes usually associated with acute anterior uveitis may instead manifest as asymptomatic eye disease.”
For their study, Dr. Liebling and coinvestigators examined the records of children seen at the Children’s Hospital of Philadelphia over a 6.5-year period. For inclusion, children had to have a physician diagnosis of JIA of any subtype and a history of uveitis.
A total of 98 children were included in the retrospective evaluation; the median age at diagnosis of JIA was 3.3 years, and the median age at first uveitis diagnosis was 5.1 years. The majority (82%) were female, 69% were antinuclear antibody (ANA) positive, and 60% had oligoarthritis – all of which have been associated with having a higher risk for developing uveitis.
However, independent of these and several other factors, the probability of having active uveitis within 45 days of a rheumatology assessment was 65% in those with active arthritis versus 42% for those with no active joints.
Their data are based on 1,229 rheumatology visits that occurred between 2013 and 2019, with a median of 13 visits per patient. Overall, arthritis was defined as being active in 17% of visits, and active uveitis was observed in 18% of rheumatology visits.
Concordance between arthritis and uveitis activity was observed 73% of the time, the researchers reported. A sensitivity analysis that excluded children with the enthesitis-related arthritis subtype of JIA, who may not undergo frequent eye exams, did not change their findings.
Decreased odds of active uveitis at any time point were seen with the use of combination biologic and nonbiologic disease-modifying antirheumatic drugs. Years from uveitis diagnosis was also associated with lower odds of active uveitis over time.
Other factors associated with lower odds of uveitis were female sex, HLA-B27 positivity, and having any subtype of JIA other than the oligoarticular subtype.
Dr. Liebling and coinvestigators concluded that, contrary to the historical dogma, arthritis and uveitis do not run distinct and unrelated courses: “In patients with JIA-U, there is a significant temporal association between arthritis and uveitis disease activity.”
The study was sponsored by the Children’s Hospital of Philadelphia Rheumatology Research Fund. The investigators for the study had no financial support from commercial sources or any other potential conflicts of interest. Dr. Angeles-Han had no conflicts of interest to disclose.

“Although there are known risk factors associated with uveitis development in children with JIA, less data are available about factors associated with uveitis flare or activity,” said Sheila T. Angeles-Han, MD, MSc, of the departments of pediatrics and ophthalmology at Cincinnati Children’s Hospital Medical Center who commented on the study in an interview.
“If proven, this knowledge has the potential to impact practice patterns and current guidelines wherein a pediatric rheumatologist who evaluates a child with JIA-associated uveitis and finds active arthritis would request an expedited ophthalmic examination,” Dr. Angeles-Han suggested.
Dr. Angeles-Han led the development of the first American College of Rheumatology/Arthritis Foundation Guideline for the Screening, Monitoring, and Treatment of JIA-Associated Uveitis, which recommends regular screening for uveitis in all children with JIA. Children found to have uveitis should then be screened at least every 3 months, and more frequently if they are taking glucocorticoids and treatment is being tapered.
JIA-associated uveitis accounts for around 20%-40% of all cases of noninfectious childhood eye inflammation, and it can run an insidious and chronic course.
“Children with acute anterior uveitis are symptomatic and tend to have a painful red eye, thus prompting an ophthalmic evaluation,” Dr. Angeles-Han explained. “This is different from children with chronic anterior uveitis who tend not to have any symptoms, thus a screening examination is critical to detect ocular inflammation.”
While the ACR/AF guideline distinguishes between acute and chronic uveitis, Dr. Liebling and colleagues explain that they did not because their experience shows that “even patients with chronic anterior uveitis, typically thought to have silent disease, may exhibit symptoms of eye pain, redness, vision changes, and photophobia.”
Conversely, they say “the JIA subtypes usually associated with acute anterior uveitis may instead manifest as asymptomatic eye disease.”
For their study, Dr. Liebling and coinvestigators examined the records of children seen at the Children’s Hospital of Philadelphia over a 6.5-year period. For inclusion, children had to have a physician diagnosis of JIA of any subtype and a history of uveitis.
A total of 98 children were included in the retrospective evaluation; the median age at diagnosis of JIA was 3.3 years, and the median age at first uveitis diagnosis was 5.1 years. The majority (82%) were female, 69% were antinuclear antibody (ANA) positive, and 60% had oligoarthritis – all of which have been associated with having a higher risk for developing uveitis.
However, independent of these and several other factors, the probability of having active uveitis within 45 days of a rheumatology assessment was 65% in those with active arthritis versus 42% for those with no active joints.
Their data are based on 1,229 rheumatology visits that occurred between 2013 and 2019, with a median of 13 visits per patient. Overall, arthritis was defined as being active in 17% of visits, and active uveitis was observed in 18% of rheumatology visits.
Concordance between arthritis and uveitis activity was observed 73% of the time, the researchers reported. A sensitivity analysis that excluded children with the enthesitis-related arthritis subtype of JIA, who may not undergo frequent eye exams, did not change their findings.
Decreased odds of active uveitis at any time point were seen with the use of combination biologic and nonbiologic disease-modifying antirheumatic drugs. Years from uveitis diagnosis was also associated with lower odds of active uveitis over time.
Other factors associated with lower odds of uveitis were female sex, HLA-B27 positivity, and having any subtype of JIA other than the oligoarticular subtype.
Dr. Liebling and coinvestigators concluded that, contrary to the historical dogma, arthritis and uveitis do not run distinct and unrelated courses: “In patients with JIA-U, there is a significant temporal association between arthritis and uveitis disease activity.”
The study was sponsored by the Children’s Hospital of Philadelphia Rheumatology Research Fund. The investigators for the study had no financial support from commercial sources or any other potential conflicts of interest. Dr. Angeles-Han had no conflicts of interest to disclose.

Children with juvenile idiopathic arthritis–associated uveitis (JIA-U) are significantly more likely to experience a flare in their eye disease if their arthritis is also worsening, a team of U.S.-based researchers has found.
In a longitudinal cohort study, children with active arthritis at the time of a routine rheumatology assessment had an almost 2.5-fold increased risk of also having active uveitis 45 days before or after the assessment than did children whose arthritis was not flaring at the rheumatology assessment.

Evaluating the impact of new pediatric brain tumor classifications
and that will have far-reaching implications for how clinicians diagnose and manage these rare and often debilitating malignancies, a leading European researcher reported at the 2020 CNS-ICNA Conjoint Meeting, held virtually this year.
“These pediatric neuronal/glioneuronal tumors are quite heterogeneous in terms of the number of different tumors and subclasses of tumors going into these groups, but they have some molecular features in common,” said David T.W. Jones, PhD, of Hopp Children’s Cancer Center in Heidelberg, Germany. “Together they represent quite a sizable portion of all childhood brain tumors, so it’s important to recognize and understand them.”
Dr. Jones noted that updated WHO classifications would add six new descriptions to the category of mixed glioneuronal tumors and one to the list of neuronal tumors. A working group of the Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy, known as cIMPACT-NOW, has recommended the expanded classifications for central nervous system tumors.
“The molecular understandings of pediatric neuro-glial tumors are critical in their management,” Roger Packer, MD, senior vice president of the Center for Neuroscience and Behavioral Health at Children’s National in Washington, said in an interview, especially as treatments targeting specific molecular structures emerge. “For those with tumors not amenable to safe, total resections, there’s little evidence that radiation or chemotherapy are effective, and molecular-targeted therapy, guided by the molecular genetic composition, increases the safe use of these new agents.”
Dr. Jones noted that “as a minimum” molecular diagnostics of pediatric low-grade glioneuronal and neuronal tumors should include a BRAF gene mutation and fusion status, as well as FGFR1 mutation plus fusion or rearrangement status.
“Ideally,” he added, “it should also have a broader copy number profile, whether that’s based on sequencing or SNP arrays or DNA methylation rate, a global DNA methylation profile to get those global molecular patterns, and also wider gene and RNA sequence to pick up some of those rarer alterations that may not be covered by targeted BRAF and FGFR1 mutations.”
The updated tumor classification will evolve to include novel tumor classes, as well as links or overlaps between the tumor classes and their characteristic underlying kinetic alterations, he noted. “Some of these profiling measures will actually be required to generate a fully WHO-compatible pathological diagnosis,” Dr. Jones said.
“This group of tumors are now just better molecularly characterized than it was 5 years ago, so in the last few years we’ve really made tremendous progress in understanding what alterations are driving some of these tumors,” he said. “That knowledge is now providing a basis for improved diagnosis and also for starting to plan more targeted treatment strategies.”
But, he added, there’s still a lot to learn about how these oncogenic mechanisms drive tumor pathogenesis. “What is the clinical costs when we really start getting down into defining these distinct molecular groups?” he said. “What are their different responses to treatment depending on different levels, where the MEKi [mitogen-activated protein kinase inhibitor] pathway might be activated and, for example, response to treatment of different subclasses of one tumor?”
Large, collaborative clinical studies will be needed to get those answers, he said.
“There are certainly some therapeutic opportunities arising in this group of tumors now, but in order to really translate those into a clinical benefit, we’re really going to need some careful planning of international studies because of the relative rarity of some of these groups,” he said.

Acute flaccid myelitis: More likely missed than diagnosed
and that can result in loss of valuable time to admit patients and begin treatment to get ahead of the virus that may cause the disease.
At the 2020 CNS-ICNA Conjoint Meeting, held virtually this year, Leslie H. Hayes, MD, of Boston Children’s Hospital presented findings of a retrospective case series from 13 institutions in the United States and Canada that determined 78% of patients eventually found to have AFM were initially misdiagnosed. About 62% were given an alternate diagnosis or multiple diagnoses, and 60% did not get a referral for further care or evaluation. The study included 175 children aged 18 years and younger when symptoms first appeared from 2014 to 2018 and who met the Centers for Disease Control and Prevention case definition of AFM.
“As it becomes more evident that AFM outbreaks are driven by enterovirus infections, treatments targeting the viral infection are likely to be most effective very early in the course of disease, necessitating a precise and early diagnosis,” Dr. Hayes said. “Thus awareness is needed to help recognize the signs of symptoms of AFM, particularly among frontline clinicians.”
One reason for misdiagnosis is that AFM has features that overlap with other neuroinflammatory disorders, she said. “In many cases the patients are misdiagnosed as having benign or self-limiting processes that would not prompt the same monitoring and level of care.”
Numbness and prodromal illnesses were associated with misdiagnosis, she said, but otherwise most presenting symptoms were similar between the misdiagnosed and correctly diagnosed patients.
Neurologic disorders with similar features to AFM that the study identified were Guillain-Barré syndrome, spinal cord pathologies such as transverse myelitis, brain pathologies including acute disseminating encephalomyelitis, acute inclusion body encephalitis and stroke, and other neuroinflammatory conditions.
“There were also many patients diagnosed as having processes that in many cases would not prompt inpatient admission, would not involve neurology consultation, and would not be treated in a similar fashion to AFM,” Dr. Hayes said.
Those diagnoses included plexopathy, neuritis, Bell’s palsy, meningoencephalitis, nonspecific infectious illness or parainfectious autoimmune disease, or musculoskeletal problems including toxic or transient synovitis, myositis, fracture or sprain, or torticollis.
“We identified preceding illness and numbness as two features associated with misdiagnosis,” Dr. Hayes said.
“We evaluated illness severity by evaluating the need for invasive and noninvasive ventilation and found that, while not statistically significant, misdiagnosed patients had a trend toward higher need for such respiratory support,” she noted. Specifically, 31.6% of misdiagnosed patients required noninvasive ventilation versus 15.8% of promptly diagnosed patients (P = .06).
Dr. Hayes characterized the rates of ICU admissions between the two groups as not statistically significant: 52.5% and 36.8% for the misdiagnosed and promptly diagnosed groups, respectively (P = .1).
Both groups of patients received intravenous immunoglobulin in similar rates (77.9% and 81.6%, respectively, P = .63), but the misdiagnosed patients were much more likely to receive steroids, 68.2% versus 44.7% (P = .008). That’s likely because steroids are the standard treatment for the neuroinflammatory disorders that they were misdiagnosed with, Dr. Hayes said.
Timely diagnosis and treatment was more of an issue for the misdiagnosed patients; their diagnosis was made on average 5 days after the onset of symptoms versus 3 days (P < .001). “We found that time to treatment, particularly time to IVIg, was significantly longer in the misdiagnosed group,” Dr. Hayes said, at 5 versus 2 days (P < .001).
