Dietary intervention that involves the target manipulation of microbiota components may improve the growth rate in children with moderate acute malnutrition, according to new research.

Moderate acute malnutrition affects more than 30 million children worldwide, according to the Food and Nutrition Bulletin. The World Health Organization defines the condition by a weight-for-height measurement that is 2 or 3 standard deviations below the international standard.

A 2014 study published in Nature has shown that malnourishment is associated with defects in children’s gut microbiota, including having microbial communities that are immature and younger than those of their healthy counterparts. Microbiota immaturity also correlates with stunted growth.

The authors of new study, which was published in the New England Journal of Medicine on April 7, 2021, wrote that nutritional interventions and treatments, such as therapeutic calorie-dense foods, have limited effectiveness because they don’t restore growth or fully address repairing the gut microbiome.

“This work supports the notion that healthy growth of children is linked to healthy development of their gut microbiota,” study author Jeffrey Gordon, MD, director of the Edison Family Center for Genome Sciences & Systems Biology at Washington University, St. Louis, said in an interview. “This, in turn, indicates that we need to have a more encompassing view of human developmental biology – one that considers both our ‘human’ and ‘microbial’ parts.”

The study establishes the impact of microbiota repair on a child’s growth rate, which may have implications on policies related to complementary feeding practices, Dr. Gorden noted.
 

Better outcomes seen with microbiota-directed complementary food prototype

For the research, 123 children with moderate acute malnutrition aged between 12 and 18 months were randomly assigned to receive a microbiota-directed complementary food prototype (MDCF-2) or ready-to-use supplementary food (RUSF). The supplementation was given to the kids twice daily for 3 months, followed by 1 month of monitoring. They looked at the weekly rate of change in the weight-for-length z score, weight-for-age z score, mid-upper-arm circumference, length-for-age z score, medical complication, gut microbiota, and blood samples in the group to determine the effectiveness of each food intervention therapy.

They found that, of the 118 children who completed the study, those in the MDCF-2 group had better outcomes than those in the RUSF group based on greater weekly growth in z scores, indicating faster growth rates. For those in the MDCF-2 group, the mean weekly change in weight-for-length z score was 0.021, compared to the RUSF group’s 0.010. When it came to weight-for-age z score, the mean weekly change was 0.017 in the MDCF-2 group and 0.010 in the RUSF group. The mean weekly changes in the mid-upper-arm circumference and length-for-age z scores were similar in both groups.

When examining blood samples of the cohort, researchers noted that 714 proteins were significantly altered after 3-month MDCF-2 supplementation, compared with 82 proteins having shown significant alterations in the RUSF group.

Overall, the findings show that repairing gut microbiota was accompanied by improved weight gain and marked changes in circulating levels of protein biomarkers and mediators of numerous aspects of healthy growth.
 

Results need to be verified on a larger scale

Tim Joos, MD, who was not part of the study, said it is surprising that MDCF-2 was better at promoting growth than existing nutritional supplements.

“The study suggests that remedying malnutrition requires more than just ensuring adequate calorie and nutrient intake,” Dr. Joos, a pediatrician at NeighborCare Health in Seattle, noted in an interview. “It is a small study and needs to be verified on a larger scale and in more diverse locations and pediatric ages (outside of the 12- to 18-month-old cohort studied).”

Wendy S. Garrett, MD, PhD, who also didn’t participate in the study, wrote in an accompanying editorial that overarching questions remain concerning the long-lasting effects of the intervention on children’s growth trajectory and cognitive development. She also said that the study “provides an abundance of fascinating microbiome profile data, plasma protein correlates, and metadata to sift through.”

Dr. Gordon and colleagues said the findings underscore the broad effects gut microbiota has on human biology and they hope this will open the door to better definitions of wellness for infants/children.

Secukinumab proved highly effective at improving skin symptoms and quality of life in 6- to 17-year-old patients with moderate to severe plaque psoriasis at 24 weeks of follow-up in an ongoing 4-year phase 2 clinical trial, Adam Reich, MD, PhD, reported at Innovations in Dermatology: Virtual Spring Conference 2021.

Secukinumab (Cosentyx), a fully human monoclonal antibody that inhibits interleukin-17A, is widely approved for treatment of psoriasis in adults. In August 2020, the biologic received an expanded indication in Europe for treatment of 6- to 17-year-olds. Two phase 3 clinical trials are underway in an effort to gain a similar broadened indication in the United States to help address the high unmet need for new treatments for psoriasis in the pediatric population, said Dr. Reich, professor and head of the department of dermatology at the University of Rzeszow (Poland).

He reported on 84 pediatric patients participating in the open-label, phase 2, international study. They were randomized to one of two weight-based dosing regimens. Those in the low-dose arm received secukinumab dosed at 75 mg if they weighed less than 50 kg and 150 mg if they weighed more. In the high-dose arm, patients got secukinumab 75 mg if they weighed less than 25 kg, 150 mg if they weighed 25-50 kg, and 300 mg if they tipped the scales in excess of 50 kg.

The primary endpoint in the study was the week-12 rate of at least a 75% improvement from baseline in the Psoriasis Area and Severity Index score, or PASI 75. The rates were similar: 92.9% of patients in the high-dose arm achieved this endpoint, as did 90.5% in the low-dose arm. The PASI 90 rates were 83.3% and 78%, the PASI 100 rates were 61.9% and 54.8%, and clear or almost clear skin, as measured by the Investigator Global Assessment, was achieved in 88.7% of the high- and 85.7% of the low-dose groups. In addition,61.9% of those in the high-dose secukinumab group and 50% in the low-dose group had a score of 0 or 1 on the Children’s Dermatology Life Quality Index – indicating psoriasis has no impact on daily quality of life, he said at the conference sponsored by MedscapeLIVE! and the producers of the Hawaii Dermatology Seminar and Caribbean Dermatology Symposium.

At week 24, roughly 95% of patients in both the low- and high-dose secukinumab groups had achieved PASI 75s, 88% reached a PASI 90 response, and 67% were at PASI 100. Nearly 60% of the low-dose and 70% of the high-dose groups had a score of 0 or 1 on the Children’s Dermatology Life Quality Index.

Treatment-emergent adverse event rates were similar in the two study arms. Of note, there was one case of new-onset inflammatory bowel disease in the high-dose group, and one case of vulvovaginal candidiasis as well.

Discussant Bruce E. Strober, MD, PhD, said that, if secukinumab gets a pediatric indication from the Food and Drug Administration, as seems likely, it won’t alter his biologic treatment hierarchy.

“I treat a lot of kids with psoriasis. We have three approved drugs now in etanercept [Enbrel], ustekinumab [Stelara], and ixekizumab [Taltz]. My bias is still towards ustekinumab because it’s infrequently dosed and that’s a huge issue for children. You want to expose them to as few injections as possible, for obvious reasons: It’s easier for parents and other caregivers,” explained Dr. Strober, a dermatologist at Yale University, New Haven, Conn., and Central Connecticut Dermatology, Cromwell, Conn.

“The other issue is in IL-17 inhibition there has been a slight signal of inflammatory bowel disease popping up in children getting these drugs, and therefore you need to screen patients in this age group very carefully – not only the patients themselves, but their family – for IBD risk. If there is any sign of that I would move the IL-17 inhibitors to the back of the line, compared to ustekinumab and etanercept. Ustekinumab is still clearly the one that I think has to be used first line,” he said.

Dr. Strober offered a final word of advice for his colleagues: “You can’t be afraid to treat children with biologic therapies. In fact, preferentially I would use a biologic therapy over methotrexate or light therapy, which is really difficult for children.”

Dr. Reich and Dr. Strober reported receiving research grants from and serving as a consultant to numerous pharmaceutical companies, including Novartis, which markets secukinumab and funded the study.

An experimental immunotherapy that contains a genetically altered version of herpes simplex virus type 1 (HSV-1) was associated with a doubling in median overall survival for children and adolescents with recurrent or progressive high-grade gliomas.

This is a rapidly fatal form of brain cancer. Among historical control patients, the median overall survival was only 5.3 months.

The new results show a median overall survival of 12.2 months.

They come from a phase 1 trial conducted in 12 patients aged 7-18 years who had high-grade gliomas. All of the patients received the experimental therapy, dubbed G207, which was infused directly into the brain tumors.

“In our secondary objectives, we saw promising overall survival data ... [and] we saw that G207 turned immunologically ‘cold’ tumors to ‘hot,’ ” said lead investigator Gregory K. Friedman, MD, from the University of Alabama at Birmingham.

Dr. Friedman presented the new data at the American Association for Cancer Research Annual Meeting 2021: Week 1 (Abstract CT018). The study was also published simultaneously online in the New England Journal of Medicine.

Although the number of patients in the study was small, the data from this early trial look promising, commented Howard Kaufman, MD, director of the Oncolytic Virus Research Laboratory at Massachusetts General Hospital, Boston, who was not involved in the study.

“This is just a horrendous disease that hasn’t really responded to anything, so seeing some signs of benefit as well as a pretty tolerable safety profile is a very important observation that I think merits further investigation,” he said in an interview.
 

Engineered virus

G207 is an oncolytic form of HSV-1 created through genetic engineering in which a neurovirulence gene was deleted and viral nucleotide reductase was disabled. The engineered mutations prevent HSV-1 from infecting normal cells while allowing the virus to replicate in tumor cells.

The oncolytic virus product can be inoculated directly into tumors to circumvent the blood-brain barrier, and it preferentially infects neural tissue, making it ideal for treating brain tumors, the investigators explain.

One example of this type of product is already on the market. Talimogene laherparepvec is an oncolytic HSV-1 therapy that was approved in 2015 by the Food and Drug Administration for local treatment (i.e., injection directly into the skin lesion) of unresectable cutaneous, subcutaneous, and nodal lesions in patients with melanoma that recurs after initial surgery.

In their article, Dr. Friedman and colleagues summarized some of the data with G207 that “provided a strong rationale for conducting a trial involving children and adolescents.

“In addition to infecting and lysing tumor cells directly, G207 can reverse tumor immune evasion, increase cross-presentation of tumor antigens, and promote an antitumor immune response even in the absence of virus permissivity,” they wrote. “A single radiation dose enhances G207 efficacy in animal models by increasing viral replication and spread.”

In preclinical studies using tumor xenografts, pediatric brain tumors were 11-fold more sensitive to G207, compared with glioblastomas in adults.

The researchers hypothesized that intratumoral G207 would increase the amount of tumor-infiltrating lymphocytes and thereby convert immunologically “cold” pediatric brain tumors to “hot” and “inflamed” tumors.
 

Phase 1 trial

The phase 1 trial included four dose cohorts of children and adolescents with a pathologically proven malignant supratentorial brain tumor of at least 1 cm in diameter that had progressed after surgery, radiotherapy, or chemotherapy.

There were three patients in each dose cohort. One cohort received 107 plaque-forming units, the second received 108 PFU, the third received 107 PFU with 5 Gy of radiation, and the fourth received 108 PFU with 5 Gy radiation.

The patients first underwent stereotactic placement of up to four intratumoral catheters. The next day, they underwent infusion of the assigned PFU doses by controlled-rate infusion over 6 hours.

For the patients who received radiation, 5 Gy were administered to the gross tumor volume within 24 hours following G207 administration.

Among the 12 patients, tumors included 10 glioblastomas, one anaplastic astrocytoma, and one high-grade glioma not otherwise specified.

Responses (radiographic, neuropathologic, or clinical) occurred in 11 of the 12 patients.

Four patients were still alive 18 months after treatment, “which exceeds the life expectancy for newly diagnosed patients,” Dr. Friedman noted. Most patients die within 1 year of being diagnosed with pediatric glioma.

The investigators also found evidence to suggest that survival may be improved for patients who experience seroconversion after exposure to HSV-1 in comparison to patients with HSV-1 antibodies from prior HSV-1 infection. The median overall survival was 18.3 months for patients who experienced seroconversion, compared with 5.1 months for three patients who, at baseline, had IgG antibodies to HSV-1.

No dose-limiting toxicities or serious adverse events attributable to G207 occurred. There were 20 grade 1 adverse events that were potentially related to G207.

There was no evidence of peripheral G207 shedding or viremia, the investigators reported.
 

Radiation effect?

Commenting on the results in an interview, Dr. Kaufman noted that the sample size (12 patients) in this study was too small to determine whether the radiation received by patients in two of the four cohorts had any additive effect.

“Whether to move forward with virus alone or to add the radiation remains an open question that I don’t think was adequately answered,” he said.

Regarding the evidence suggesting that survival was better among patients who did not have antibodies to HSV-1 at baseline, Dr. Kaufman said, “We’ve looked at that in the melanoma population but haven’t seen any correlation there, so that’s interesting.”

The finding could be related to the fact that this was a pediatric population, or it could be related to the location of the tumors in the brain.

An experimental immunotherapy that contains a genetically altered version of herpes simplex virus type 1 (HSV-1) was associated with a doubling in median overall survival for children and adolescents with recurrent or progressive high-grade gliomas.

This is a rapidly fatal form of brain cancer. Among historical control patients, the median overall survival was only 5.3 months.

The new results show a median overall survival of 12.2 months.

They come from a phase 1 trial conducted in 12 patients aged 7-18 years who had high-grade gliomas. All of the patients received the experimental therapy, dubbed G207, which was infused directly into the brain tumors.

“In our secondary objectives, we saw promising overall survival data ... [and] we saw that G207 turned immunologically ‘cold’ tumors to ‘hot,’ ” said lead investigator Gregory K. Friedman, MD, from the University of Alabama at Birmingham.

Dr. Friedman presented the new data at the American Association for Cancer Research Annual Meeting 2021: Week 1 (Abstract CT018). The study was also published simultaneously online in the New England Journal of Medicine.

Although the number of patients in the study was small, the data from this early trial look promising, commented Howard Kaufman, MD, director of the Oncolytic Virus Research Laboratory at Massachusetts General Hospital, Boston, who was not involved in the study.

“This is just a horrendous disease that hasn’t really responded to anything, so seeing some signs of benefit as well as a pretty tolerable safety profile is a very important observation that I think merits further investigation,” he said in an interview.
 

Engineered virus

G207 is an oncolytic form of HSV-1 created through genetic engineering in which a neurovirulence gene was deleted and viral nucleotide reductase was disabled. The engineered mutations prevent HSV-1 from infecting normal cells while allowing the virus to replicate in tumor cells.

The oncolytic virus product can be inoculated directly into tumors to circumvent the blood-brain barrier, and it preferentially infects neural tissue, making it ideal for treating brain tumors, the investigators explain.

One example of this type of product is already on the market. Talimogene laherparepvec is an oncolytic HSV-1 therapy that was approved in 2015 by the Food and Drug Administration for local treatment (i.e., injection directly into the skin lesion) of unresectable cutaneous, subcutaneous, and nodal lesions in patients with melanoma that recurs after initial surgery.

In their article, Dr. Friedman and colleagues summarized some of the data with G207 that “provided a strong rationale for conducting a trial involving children and adolescents.

“In addition to infecting and lysing tumor cells directly, G207 can reverse tumor immune evasion, increase cross-presentation of tumor antigens, and promote an antitumor immune response even in the absence of virus permissivity,” they wrote. “A single radiation dose enhances G207 efficacy in animal models by increasing viral replication and spread.”

In preclinical studies using tumor xenografts, pediatric brain tumors were 11-fold more sensitive to G207, compared with glioblastomas in adults.

The researchers hypothesized that intratumoral G207 would increase the amount of tumor-infiltrating lymphocytes and thereby convert immunologically “cold” pediatric brain tumors to “hot” and “inflamed” tumors.
 

Phase 1 trial

The phase 1 trial included four dose cohorts of children and adolescents with a pathologically proven malignant supratentorial brain tumor of at least 1 cm in diameter that had progressed after surgery, radiotherapy, or chemotherapy.

There were three patients in each dose cohort. One cohort received 107 plaque-forming units, the second received 108 PFU, the third received 107 PFU with 5 Gy of radiation, and the fourth received 108 PFU with 5 Gy radiation.

The patients first underwent stereotactic placement of up to four intratumoral catheters. The next day, they underwent infusion of the assigned PFU doses by controlled-rate infusion over 6 hours.

For the patients who received radiation, 5 Gy were administered to the gross tumor volume within 24 hours following G207 administration.

Among the 12 patients, tumors included 10 glioblastomas, one anaplastic astrocytoma, and one high-grade glioma not otherwise specified.

Responses (radiographic, neuropathologic, or clinical) occurred in 11 of the 12 patients.

Four patients were still alive 18 months after treatment, “which exceeds the life expectancy for newly diagnosed patients,” Dr. Friedman noted. Most patients die within 1 year of being diagnosed with pediatric glioma.

The investigators also found evidence to suggest that survival may be improved for patients who experience seroconversion after exposure to HSV-1 in comparison to patients with HSV-1 antibodies from prior HSV-1 infection. The median overall survival was 18.3 months for patients who experienced seroconversion, compared with 5.1 months for three patients who, at baseline, had IgG antibodies to HSV-1.

No dose-limiting toxicities or serious adverse events attributable to G207 occurred. There were 20 grade 1 adverse events that were potentially related to G207.

There was no evidence of peripheral G207 shedding or viremia, the investigators reported.
 

Radiation effect?

Commenting on the results in an interview, Dr. Kaufman noted that the sample size (12 patients) in this study was too small to determine whether the radiation received by patients in two of the four cohorts had any additive effect.

“Whether to move forward with virus alone or to add the radiation remains an open question that I don’t think was adequately answered,” he said.

Regarding the evidence suggesting that survival was better among patients who did not have antibodies to HSV-1 at baseline, Dr. Kaufman said, “We’ve looked at that in the melanoma population but haven’t seen any correlation there, so that’s interesting.”

The finding could be related to the fact that this was a pediatric population, or it could be related to the location of the tumors in the brain.

“It’s an interesting finding, and it suggests that, in future studies, they might want to select patients who are HSV seronegative up front,” he said.

Darier disease (DD)(also known as dyskeratosis follicularis) is a rare, autosomal-dominant genodermatosis characterized by greasy, rough, keratotic papules; typical nail abnormalities; mucosal changes; and characteristic dyskeratotic acantholysis that is called corps ronds and grains on histopathologic analysis. Darier disease is caused by mutations of the ATP2A2 gene on chromosome 12q23-24.^1,2

Because of the autosomal-dominant pattern of inheritance in DD, if either parent is affected by DD, approximately 50% of their offspring will have the disorder. Therefore, couples need to be offered genetic counseling at a preconception visit or early in pregnancy. Although penetrance of DD is complete, spontaneous mutations are frequent and expressivity is variable¹; prenatal diagnosis, though available since the 1980s, is therefore unreliable in DD, given the considerable variation in phenotypic expressivity. Differing phenotypes underscore the importance of proper counseling by the treating dermatologist or other provider. Females with a mild or nearly undetectable phenotype can give birth to a child with severe disease.

Lack of clear understanding about the variable phenotypic expressivity of DD can cause considerable anger, anxiety, guilt, psychological trauma, and fear in parents, should their child later develop a severe phenotype. They may feel that they were not properly prepared for the outcome. The physician-parent or physician-patient relationship can be negatively impacted if ongoing counseling is inadequate.

Clinically, DD presents in early adolescence (age range, 6–20 years) in most patients, which means that the disease and female reproductive years are contemporaneous. However, gynecologic and obstetric issues and complications of DD rarely have been addressed.³ Oromucosal involvement in DD is reported in 13% to 50% of cases, yet vaginal and cervical mucosal involvement rarely has been described,^4,5 likely due to underreporting. Therefore, in this rare disease, it is important to address these aspects so that the patients are provided with appropriate management options.

Implications for Cervical Screening and Papanicolaou Tests

Cytopathologic findings of a Papanicolaou test taken from a patient with DD can lead to erroneous diagnosis of a low-grade squamous intraepithelial lesion due to cervical involvement by the disease process; therefore, correct interpretation of a smear may be inappropriate and erroneous. The cytopathologist needs to be informed of the patient’s diagnosis of DD in advance for appropriate reporting.^5,6

Obstetric Implications

Fertility is normal in DD patients, and pregnancy usually has a normal course; however, exacerbation and remission of disease have been reported. de la Rosa Carrillo⁷ reported a case of vegetating DD during pregnancy. He described it as an exacerbation with concurrent bacterial infection and bilateral external otitis.⁷ Spouge et al⁸ reported a case of a 58-year-old woman who was the mother of 4 DD patients. She experienced an exacerbation of DD during all 6 pregnancies but improved immediately postpartum.⁸ Espy et al⁹ evaluated 8 cases of women with DD and described spontaneous improvement of the disorder during pregnancy (1 case) or while taking an oral contraceptive (3 cases).

Prenatal Counseling

Women with DD should be encouraged to talk to their dermatologist, obstetrician, or other provider of prenatal care regarding plans for pregnancy, labor, and delivery, as these events might be affected by the disorder. During pregnancy, careful monitoring and self-care remain essential. Simple measures to reduce the impact of irritants on DD during pregnancy include keeping the skin cool, using a soothing moisturizer, applying photoprotection, and using sunscreen. Treatment with systemic retinoids must be avoided if pregnancy is planned.

Warty plaques and papules of DD can involve flexures (groin, vulva, and perineum), with resultant malodor and pruritus¹⁰ as well as the potential for (drug resistant) secondary infection (eg, Staphylococcus aureus, group B Streptococcus, viruses [eg, Kaposi varicelliform eruption]). Skin swabs should be taken for culture and susceptibility testing, and infection should be treated at the earliest sign.

Management Concerns During Pregnancy and Delivery

Because the benefits of treating DD might outweigh risk in certain cases, thorough discussion with the patient about options is recommended, including the following concerns:

• Because mucocutaneous elasticity of the birth canal, including the vulva, perineum, and groin, is essential for nontraumatic vaginal delivery, it might be necessary to schedule an elective cesarean delivery in DD patients in whom these regions are involved.¹¹

• In females with lower abdominal lesions, using a Pfannenstiel-Kerr incision for cesarean delivery might be problematic.¹¹

• A single case report has described successful anesthetic management of labor, delivery, and postpartum care in a DD patient.¹² Involvement of the skin of the back might preclude safe administration of regional anesthesia; however, because DD lesions are considered noninfectious, the authors operatively administered a subarachnoid block at the L3-L4 interspace through a lesion-free area. Postpartum, the patient was observed in the intensive care unit. She and the baby remained stable; she did not develop infectious complications, including a central nervous system infection.¹²

•Mucosal involvement is relatively rare in DD and has not been reported to compromise airway management.⁸

Postnatal Considerations

Breastfeeding might have to be stopped early or withheld altogether if there is widespread involvement of the skin of the breast or the nipple.¹¹ Darier disease has been associated with neuropsychiatric manifestations, including major depression (30%), suicide attempts (13%), suicidal thoughts (31%), cyclothymia, bipolar disorder (4%), and epilepsy (3%).^13,14 Therefore, patients should be screened for postpartum psychiatric manifestations at an early follow-up visit.

Final Thoughts

Although the etiology of DD is well known, the gynelogic and obstretric implications of this genodermatosis have rarely been described. This brief commentary is an attempt to provide the important information to a practicing dermatologist for appropriate management of female DD patients.

For as many disorders of cornification and types of ichthyosis that have been shown to benefit from retinoids, a seemingly equal number have no data or show no improvement.

According to a consensus statement published in the February issue of Pediatric Dermatology, adequate data exist in the medical literature to demonstrate an improvement in use of systemic retinoids for select genotypes of congenital ichthyosiform erythroderma, epidermolytic ichthyosis, erythrokeratodermia variabilis, harlequin ichthyosis, IFAP syndrome (ichthyosis with confetti, ichthyosis follicularis, atrichia, and photophobia), KID syndrome (keratitis-ichthyosis-deafness), KLICK syndrome (keratosis linearis with ichthyosis congenita and sclerosing keratoderma), lamellar ichthyosis, loricrin keratoderma, neutral lipid storage disease with ichthyosis, recessive X-linked ichthyosis, and Sjögren-Larsson syndrome.

At the same time, limited or no data exist to support the use of systemic retinoids for CHILD syndrome (congenital hemidysplasia with ichthyosiform erythroderma and limb defects), CHIME syndrome (colobomas, heart defects, ichthyosiform dermatosis, intellectual disability, and either ear defects or epilepsy), Conradi-Hunermann-Happle syndrome, ichthyosis-hypotrichosis, ichthyosis-hypotrichosis-sclerosis cholangitis, ichthyosis prematurity syndrome, MEDNIK syndrome (mental retardation, enteropathy, deafness, peripheral neuropathy, ichthyosis, and keratoderma), peeling skin disease, Refsum syndrome, and trichothiodystrophy, according to the statement.

“In particular, we did note that, with any disorder that was associated with atopy, the retinoids were often counterproductive,” one of the consensus statement cochairs, Andrea L. Zaenglein, MD, said during the Society for Pediatric Dermatology pre-AAD meeting. “In Netherton syndrome, for example, retinoids seemed to make the skin fragility a lot worse, so typically, they would be avoided in those patients.”

The statement, which she assembled with cochair pediatric dermatologist Moise L. Levy, MD, professor of pediatrics, University of Texas at Austin, and 21 other multidisciplinary experts, recommends considering use of topical retinoids to help decrease scaling of the skin,“but [they] are particularly helpful for more localized complications of ichthyosis, such as digital contractures and ectropion,” said Dr. Zaenglein, professor of dermatology and pediatrics at Penn State University, Hershey. “A lot of it has to do with the size and the volume of the tubes and getting enough [product] to be able to apply it over larger areas. We do tend to use them more focally.”

While systemic absorption can occur with widespread use, no specific lab monitoring is required. Dr. Zaenglein and her colleagues also recommend avoiding the use of tazarotene during pregnancy, since it is contraindicated in pregnancy (category X), but monthly pregnancy tests are not recommended.

During an overview of the document at the meeting, she noted that the recommended dosing for both isotretinoin and acitretin is 0.5-1.0 mg/kg per day and the side effects tend to be dose dependent, “except teratogenicity, which can occur with even low doses of systemic retinoid exposure and early on in pregnancy.” The authors also advise patients to consider drug holidays or lower doses “especially during warmer, more humid months, where you might not need the higher doses to achieve cutaneous effects,” she said.

They emphasized the importance of avoiding pregnancy for 3 years after completion of treatment with acitretin. “While the half-life of acitretin is 49 hours, it’s easily converted with any alcohol exposure to etretinate,” Dr. Zaenglein noted. “Then, the half-life is 120 days.”

The statement, which was sponsored by the Pediatric Dermatology Research Alliance (PEDRA), also addresses the clinical considerations and consequences of long-term systemic retinoid use on bone health, such as premature epiphyseal closure in preadolescent children. “In general, this risk is greater with higher doses of therapies – above 1 mg/kg per day – and over prolonged periods of time, typically 4-6 years,” she said. Other potential effects on bone health include calcifications of tendons and ligaments, osteophytes or “bone spurs,” DISH (diffuse idiopathic skeletal hyperostosis), and potential alterations in bone density and growth.

“We also have to worry about concomitant effects of contraception, particularly if you’re using progestin-only formulations that carry a black box warning for osteoporosis,” Dr. Zaenglein said. “It is recommended that you limit their use to 3 years.” Other factors to consider include genetic risk and modifiable factors that affect bone health, such as diet and physical activity, which may impact susceptibility to systemic retinoid bone toxicity and should be discussed with the patient.

Recommended bone monitoring in children starts with a comprehensive family and personal medical history for skeletal toxicity risk factors, followed by an annual growth assessment (height, weight, body mass index, and growth curve), asking regularly about musculoskeletal symptoms, and following up with appropriate imaging. “Inquiring about their diet is recommended as well, so making sure they’re getting sufficient amounts of calcium and vitamin D, and no additional vitamin A sources that may compound the side effects from systemic retinoids,” Dr. Zaenglein said.

The document also advises that a baseline skeletal radiographic survey be performed in patients aged 16-18 years. This may include imaging of the lateral cervical and thoracic spine, lateral view of the calcanei to include Achilles tendon, hips and symptomatic areas, and bone density evaluation.

The statement addressed the psychiatric considerations and consequences of long-term systemic retinoid use. One cross-sectional study of children with ichthyosis found that 30% screened positive for depression and 38% screened positive for anxiety, “but the role of retinoids is unclear,” Dr. Zaenglein said. “It’s a complicated matter, but patients with a personal history of depression, anxiety, and other affective disorders prior to initiation of systemic retinoid treatment should be monitored carefully for exacerbation of symptoms. Comanagement with a mental health provider should be considered.”

As for contraception considerations with long-term systemic retinoid therapy use, the authors recommend that two forms of contraception be used. “Consider long-acting reversible contraception, especially in sexually active adolescents who have a history of noncompliance, or to remove the risk of teratogenicity for them,” she said. “We’re not sure what additive effects progestin/lower estrogen have on long-term cardiovascular health, including lipids and bone density.”

The authors noted that iPLEDGE is not designed for long-term use. “It’s really designed for the on-label use of systemic retinoids in severe acne, where you’re using it for 5-6 months, not for 5-6 years,” Dr. Zaenglein said. “iPLEDGE does impose significant and financial barriers for our patients. More advocacy is needed to adapt that program for our patients.”

She and her coauthors acknowledged practice gaps and unmet needs in patients with disorders of cornification/types of ichthyosis, including the optimal formulation of retinoids based on ichthyosis subtype, whether there is a benefit to intermittent therapy with respect to risk of toxicity and maintenance of efficacy, and how to minimize the bone-related changes that can occur with treatment. “These are some of the things that we can look further into,” she said. “For now, though, retinoids can improve function and quality of life in patients with ichthyosis and disorders of cornification. Many questions still exist, and more data and research are needed.”

Sun Pharmaceuticals and the Foundation for Ichthyosis and Related Skin Types (FIRST) provided an unrestricted grant for development of the recommendations.

Dr. Zaenglein disclosed that she is a consultant for Pfizer. She is also an advisory board member for Dermata, Sol-Gel, Regeneron, Verrica, and Cassiopea, and has conducted contracted research for AbbVie, Incyte, Arcutis, and Pfizer. The other authors disclosed serving as investigators, advisers, consultants, and/or had other relationships with various pharmaceutical companies.

For as many disorders of cornification and types of ichthyosis that have been shown to benefit from retinoids, a seemingly equal number have no data or show no improvement.

According to a consensus statement published in the February issue of Pediatric Dermatology, adequate data exist in the medical literature to demonstrate an improvement in use of systemic retinoids for select genotypes of congenital ichthyosiform erythroderma, epidermolytic ichthyosis, erythrokeratodermia variabilis, harlequin ichthyosis, IFAP syndrome (ichthyosis with confetti, ichthyosis follicularis, atrichia, and photophobia), KID syndrome (keratitis-ichthyosis-deafness), KLICK syndrome (keratosis linearis with ichthyosis congenita and sclerosing keratoderma), lamellar ichthyosis, loricrin keratoderma, neutral lipid storage disease with ichthyosis, recessive X-linked ichthyosis, and Sjögren-Larsson syndrome.

At the same time, limited or no data exist to support the use of systemic retinoids for CHILD syndrome (congenital hemidysplasia with ichthyosiform erythroderma and limb defects), CHIME syndrome (colobomas, heart defects, ichthyosiform dermatosis, intellectual disability, and either ear defects or epilepsy), Conradi-Hunermann-Happle syndrome, ichthyosis-hypotrichosis, ichthyosis-hypotrichosis-sclerosis cholangitis, ichthyosis prematurity syndrome, MEDNIK syndrome (mental retardation, enteropathy, deafness, peripheral neuropathy, ichthyosis, and keratoderma), peeling skin disease, Refsum syndrome, and trichothiodystrophy, according to the statement.

“In particular, we did note that, with any disorder that was associated with atopy, the retinoids were often counterproductive,” one of the consensus statement cochairs, Andrea L. Zaenglein, MD, said during the Society for Pediatric Dermatology pre-AAD meeting. “In Netherton syndrome, for example, retinoids seemed to make the skin fragility a lot worse, so typically, they would be avoided in those patients.”

The statement, which she assembled with cochair pediatric dermatologist Moise L. Levy, MD, professor of pediatrics, University of Texas at Austin, and 21 other multidisciplinary experts, recommends considering use of topical retinoids to help decrease scaling of the skin,“but [they] are particularly helpful for more localized complications of ichthyosis, such as digital contractures and ectropion,” said Dr. Zaenglein, professor of dermatology and pediatrics at Penn State University, Hershey. “A lot of it has to do with the size and the volume of the tubes and getting enough [product] to be able to apply it over larger areas. We do tend to use them more focally.”

Arkansas has become the first state to pass a law prohibiting doctors from giving gender-affirming medical treatments to transgender youths, CNN reported.

Gov. Asa Hutchinson had vetoed the bill on April 5, calling it a “product of the cultural war in America.” But on April 6, the state House and Senate voted to override the veto, making it state law, CNN reported.

At least 17 other states are considering similar legislation, but the Arkansas bill was the first to reach the governor’s desk, the Washington Post reported.

The bill bans doctors from prescribing puberty blockers, hormone therapies, or genital-altering surgeries for anybody under 18. Ever referring a youth for such treatment from another doctor is prohibited.

“It is of grave concern to the General Assembly that the medical community is allowing individuals who experience distress at identifying with their biological sex to be subjects of irreversible and drastic nongenital gender reassignment surgery and irreversible, permanently sterilizing genital gender reassignment surgery, despite the lack of studies showing that the benefits of such extreme interventions outweigh the risks,” the text of the bill said.

Gov. Hutchinson, a Republican, had called the measure a “vast government overreach” in announcing his veto.

“The bill is overbroad, extreme, and does not grandfather those young people who are currently under hormone treatment,” Gov. Hutchinson said. “The young people who are currently under a doctor’s care will be without treatment when this law goes into effect. That means they will be looking to the black market or go out of state ... to find the treatment that they want and need. This is not the right path to put them on.”

Many medical groups have come out against this kind of legislation. The American Academy of Child and Adolescent Psychiatry says it “strongly opposes any efforts – legal, legislative, and otherwise – to block access to these recognized interventions.”

Chase Strangio, the deputy director for transgender justice with the American Civil Liberty Union’s LGBTQ & HIV Project, complimented Gov. Hutchinson for his veto. On April 6, he said the ACLU is preparing to challenge the bill in court, CNN said.

The use of telehealth may have skyrocketed during the COVID-19 pandemic, but it also exposed a digital divide, speaker after speaker said during a panel discussion at the Society for Pediatric Dermatology (SPD) pre-AAD meeting.

“We have seen large numbers of children struggle with access to school and access to health care because of lack of access to devices, challenges of broadband Internet access, culture, language, and educational barriers – just having trouble being comfortable with this technology,” said Natalie Pageler, MD, a pediatric intensivist and chief medical information officer at Stanford Children’s Health, Palo Alto, Calif.

“There are also privacy concerns, especially in situations where there are multiple families within a household. Finally, it’s important to remember that policy and reimbursement issues may have a significant effect on some of the socioeconomic barriers,” she added. “For example, many of our families who don’t have access to audio and video may be able to do a telephone call, but it’s important that telephone calls be considered a form of telehealth and be reimbursed to help increase the access to health care by these families. It also makes it easier to facilitate coordination of care. All of this leads to decreased time and costs for patients, families, and providers.”

Within the first few weeks of the pandemic, Dr. Pageler and colleagues at Stanford Children’s Health observed an increase from about 20 telehealth visits per day to more than 700 per day, which has held stable. While the benefits of telehealth are clear, many perceived barriers exist. In a study conducted prior to the COVID-19 pandemic, researchers identified a wide variety of barriers to implementation of telehealth, led by reimbursement, followed by poor business model sustainability, lack of provider time, and provider interest.

“Some of the barriers, like patient preferences for inpatient care, lack of provider interest in telehealth, and lack of provider time were easily overcome during the COVID pandemic,” Dr. Pageler said. “We dedicated the time to train immediately, because the need was so great.”

In 2018, Patrick McMahon, MD, and colleagues at Children’s Hospital of Philadelphia, launched a teledermatology program that provided direct-to-patient “E-visits” and recently pivoted to using this service only for acne patients through a program called “Acne Express.” The out-of-pocket cost to patients is $50 per consult and nearly 1,500 cases have been completed since 2018, which has saved patients and their parents an estimated 65,000 miles driving to the clinic.

To optimize the teledermatology experience, he suggested four pillars: educate, optimize, reach out, and tailor. “I think we need to draw upon some of the digital education we already have, including a handout for patients [on the SPD website] that offers tips on taking a clear photograph on their smartphones,” he said. “We’re also trying to use some of the cases and learnings from our teledermatology experiences to teach the providers. We are setting up CME modules that are sort of a flashcard-based teaching mechanism.”

To optimize teledermatology experiences, he continued, tracking demographics, diagnoses, number of cases, and turnaround time is helpful. “We can then track who’s coming in to see us at follow-up after a new visit through telehealth,” Dr. McMahon said. “This helps us repurpose things, pivot as needed, and find any glitches. Surveying the families is also critical. Finally, we need clinical support to tee-up visits and to ensure photos are submitted and efficient, and to match diagnoses and family preference with the right modality.”

Another panelist, Justin M. Ko, MD, MBA, who chairs the American Academy of Dermatology’s Task Force on Augmented Intelligence, said that digitally enabled and artificial intelligence (AI)-augmented care delivery offers a “unique opportunity” for increasing access and increasing the value of care delivered to patients.

“The role that we play as clinicians is central, and I think we can make significant strides by doing two things,” said Dr. Ko, chief of medical dermatology for Stanford (Calif.) Health Care. “One: extending the reach of our expertise, and the second: scaling the impact of the care we deliver by clinician-driven, patient-centered, digitally-enabled, AI-augmented care delivery innovation. This opportunity for digital care transformation is more than just a transition from in-person visits to video visits. We have to look at this as an opportunity to leverage the unique aspects of digital capabilities and fundamentally reimagine how we deliver care.”

The AAD’s Position Statement on Augmented Intelligence was published in 2019.

Between March and June of 2021, Neil S. Prose, MD, conducted about 300 televisits with patients. “I had a few spectacular visits where, for example, a teenage patient who had been challenging showed me all of her artwork and we became instantly more connected,” said Dr. Prose, professor of dermatology, pediatrics, and global health at Duke University, Durham, N.C. “Then there’s the potential for a long-term improvement in health care for some patients.”

Ko, MD, MBA, who chairs the American Academy of Dermatology’s Task Force on Augmented Intelligence, said that digitally enabled and artificial intelligence (AI)-augmented care delivery offers a “unique opportunity” for increasing access and increasing the value of care delivered to patients.

“The role that we play as clinicians is central, and I think we can make significant strides by doing two things,” said Dr. Ko, chief of medical dermatology for Stanford (Calif.) Health Care. “One: extending the reach of our expertise, and the second: scaling the impact of the care we deliver by clinician-driven, patient-centered, digitally-enabled, AI-augmented care delivery innovation. This opportunity for digital care transformation is more than just a transition from in-person visits to video visits. We have to look at this as an opportunity to leverage the unique aspects of digital capabilities and fundamentally reimagine how we deliver care.”

The AAD’s Position Statement on Augmented Intelligence was published in 2019.

Between March and June of 2021, Neil S. Prose, MD, conducted about 300 televisits with patients. “I had a few spectacular visits where, for example, a teenage patient who had been challenging showed me all of her artwork and we became instantly more connected,” said Dr. Prose, professor of dermatology, pediatrics, and global health at Duke University, Durham, N.C. “Then there’s the potential for a long-term improvement in health care for some patients.”

The use of telehealth may have skyrocketed during the COVID-19 pandemic, but it also exposed a digital divide, speaker after speaker said during a panel discussion at the Society for Pediatric Dermatology (SPD) pre-AAD meeting.

“We have seen large numbers of children struggle with access to school and access to health care because of lack of access to devices, challenges of broadband Internet access, culture, language, and educational barriers – just having trouble being comfortable with this technology,” said Natalie Pageler, MD, a pediatric intensivist and chief medical information officer at Stanford Children’s Health, Palo Alto, Calif.

“There are also privacy concerns, especially in situations where there are multiple families within a household. Finally, it’s important to remember that policy and reimbursement issues may have a significant effect on some of the socioeconomic barriers,” she added. “For example, many of our families who don’t have access to audio and video may be able to do a telephone call, but it’s important that telephone calls be considered a form of telehealth and be reimbursed to help increase the access to health care by these families. It also makes it easier to facilitate coordination of care. All of this leads to decreased time and costs for patients, families, and providers.”

Within the first few weeks of the pandemic, Dr. Pageler and colleagues at Stanford Children’s Health observed an increase from about 20 telehealth visits per day to more than 700 per day, which has held stable. While the benefits of telehealth are clear, many perceived barriers exist. In a study conducted prior to the COVID-19 pandemic, researchers identified a wide variety of barriers to implementation of telehealth, led by reimbursement, followed by poor business model sustainability, lack of provider time, and provider interest.

“Some of the barriers, like patient preferences for inpatient care, lack of provider interest in telehealth, and lack of provider time were easily overcome during the COVID pandemic,” Dr. Pageler said. “We dedicated the time to train immediately, because the need was so great.”

In 2018, Patrick McMahon, MD, and colleagues at Children’s Hospital of Philadelphia, launched a teledermatology program that provided direct-to-patient “E-visits” and recently pivoted to using this service only for acne patients through a program called “Acne Express.” The out-of-pocket cost to patients is $50 per consult and nearly 1,500 cases have been completed since 2018, which has saved patients and their parents an estimated 65,000 miles driving to the clinic.

To optimize the teledermatology experience, he suggested four pillars: educate, optimize, reach out, and tailor. “I think we need to draw upon some of the digital education we already have, including a handout for patients [on the SPD website] that offers tips on taking a clear photograph on their smartphones,” he said. “We’re also trying to use some of the cases and learnings from our teledermatology experiences to teach the providers. We are setting up CME modules that are sort of a flashcard-based teaching mechanism.”

To optimize teledermatology experiences, he continued, tracking demographics, diagnoses, number of cases, and turnaround time is helpful. “We can then track who’s coming in to see us at follow-up after a new visit through telehealth,” Dr. McMahon said. “This helps us repurpose things, pivot as needed, and find any glitches. Surveying the families is also critical. Finally, we need clinical support to tee-up visits and to ensure photos are submitted and efficient, and to match diagnoses and family preference with the right modality.”

Ko, MD, MBA, who chairs the American Academy of Dermatology’s Task Force on Augmented Intelligence, said that digitally enabled and artificial intelligence (AI)-augmented care delivery offers a “unique opportunity” for increasing access and increasing the value of care delivered to patients.

There is no question that none of us, not just pediatricians, is doing a very good job of dealing with the obesity problem this nation faces. We can agree that a more active lifestyle that includes spells of vigorous activity is important for weight management. We know that in general overweight people sleep less than do those whose basal metabolic rate is normal. And, of course, we know that a diet high in calorie-dense foods is associated with unhealthy weight gain.

Not surprisingly, overweight individuals are usually struggling with all three of these challenges. They are less active, get too little sleep, and are ingesting a diet that is too calorie dense. In other words, they would benefit from a total lifestyle reboot. But you know as well as I do a change of that magnitude is much easier said than done. Few families can afford nor would they have the appetite for sending their children to a “fat camp” for 6 months with no guarantee of success.

Instead of throwing up our hands in the face of this monumental task or attacking it at close range, maybe we should aim our efforts at the risk associations that will yield the best results for our efforts. A group of researchers at the University of South Australia has just published a study in Pediatrics in which they provide some data that may help us target our interventions with obese and overweight children. The researchers did not investigate diet, but used accelerometers to determine how much time each child spent sleeping and a variety of activity levels. They then determined what effect changes in the child’s allocation of activity had on their adiposity.

The investigators found on a minute-to-minute basis that an increase in a child’s moderate-to-vigorous physical activity (MVPA) was up to six times more effective at influencing adiposity than was a decrease in sedentary time or an increase in sleep duration. For example, 17 minutes of MVPA had the same beneficial effect as 52 minutes more sleep or 56 minutes less sedentary time. Interestingly and somewhat surprisingly, the researchers found that light activity was positively associated with adiposity.

For those of us in primary care, this study from Australia suggests that our time (and the parents’ time) would be best spent figuring out how to include more MVPA in the child’s day and not focus so much on sleep duration and sedentary intervals.

However, before one can make any recommendation one must first have a clear understanding of how the child and his family spend the day. This process can be done in the office by interviewing the family. I have found that this is not as time consuming as one might think and often yields some valuable additional insight into the family’s dynamics. Sending the family home with an hourly log to be filled in or asking them to use a smartphone to record information will also work.

I must admit that at first I found the results of this study ran counter to my intuition. I have always felt that sleep is the linchpin to the solution of a variety of health style related problems. In my construct, more sleep has always been the first and easy answer and decreasing screen time the second. But, it turns out that increasing MVPA may give us the biggest bang for the buck. Which is fine with me.

The problem facing us is how we can be creative in adding that 20 minutes of vigorous activity. In most communities, we have allowed the school system to drop the ball. We can hope that this study will be confirmed or at least widely publicized. It feels like it is time to guarantee that every child gets a robust gym class every school day.

Approximately 40,000 children in the United States have lost a parent to COVID-19, based on data from a combination of death counts and simulation models.

The scale of mortality from COVID-19 among adults in the United States merits efforts to monitor how many children have lost a parent as a result of the pandemic, wrote Rachel Kidman, PhD, of Stony Brook (N.Y.) University and colleagues.

In a study published in JAMA Pediatrics, the researchers used kinship networks of White and Black individuals in the United States to estimate parental bereavement. They combined deaths from COVID-19 as of February 2021 and combined them with excess deaths, and estimated future bereavement based on a herd immunity scenario.

Overall, the model suggested that each death from COVID-19 results in potential parental bereavement for 0.78 children aged 0-17 years, representing an increase of 17.5%-20.2% in parental bereavement. The model indicated that, as of February 2021, 37,337 children aged 0-17 years had lost a parent to COVID-19, including 11,366 children age 0-9 years and 31,661 children and teens aged 10-17 years. A total of 20,600 of these children were non-Hispanic White and 7,600 were Black. Black children accounted for 20% of the bereaved children, although they account for approximately 14% of children aged 0-17 years in the United States, the researchers noted.

Including the excess death estimate, which refers to the difference between observed and expected deaths for the remainder of the pandemic, raised the total bereaved children to 43,000. A future mortality scenario using a total of 1,500,000 deaths from COVID-19 based on a natural herd immunity strategy increased the total estimate of bereaved children to 116,922.

The study findings were limited by several factors including the lack of data on nonparental primary caregivers, and the use of demographic models rather than survey or administrative data, the researchers noted.

However, the huge number of children who have experienced the death of a parent because of COVID-19 emphasizes the need for reforms to address health, educational, and economic impacts of this mass bereavement on children and teens, they said.

“Parentally bereaved children will also need targeted support to help with grief, particularly during this period of heightened social isolation,” they emphasized.

Establishment of a national child bereavement cohort could identify children early in the bereavement process to help ensure that they are connected to local supportive care and monitored for health and behavior problems, the researchers said. In addition, such a cohort could be used as a basis for a longitudinal study of the impact of mass parental bereavement during a unique period of social isolation and economic uncertainty, they concluded.
 

Study spotlights gaps in mental health care

The study is an important reminder of how COVID-19 has disrupted children’s lives, said Herschel Lessin, MD, of Children’s Medical Group in Poughkeepsie, N.Y., in an interview. Losing a parent because of COVID-19 is one more tragedy on the list of social and emotional disasters the pandemic has wrought on children, he said.

“There has to be some sort of national response to help children through all of this, not just one item at a time,” Dr. Lessin said. However, the management of children’s mental health in the United States has been subpar for decades, he noted, with few clinicians trained to specialize in treating behavioral and mental health issues in children. Consequently, more general pediatricians will continue to be faced with the mental health issues of bereaved children who desperately need support, he said.

Money remains a key barrier, as it keeps qualified clinicians from entering the field of pediatric mental and behavioral health, and even where there are mental health providers, most do not take insurance and have long waiting lists, Dr. Lessin noted.

General pediatricians were seeing more patients with ADHD, anxiety, and depression before the advent of COVID-19, though most are not trained in managing these conditions, said Dr. Lessin. “Approximately 25%-30% of my visits now are mental health related, and the pandemic will make it geometrically worse,” he said.

The current study, with its dramatic estimates of the number of children who have lost a parent because of COVID-19, may bring attention to the fact that more training and money are needed to support mental health programs for children, he said.

Lead author Dr. Kidman had no financial conflicts to disclose. The study was supported by grants to corresponding author Ashton M. Verdery, PhD, from the National Institute on Aging and the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Dr. Lessin had no financial conflicts but serves on the Pediatric News editorial advisory board.

Nonalcoholic fatty liver disease (NAFLD) in children is almost always caused by excess body weight, not other etiologies, based on a retrospective analysis of 900 patients.

Just 2% of children with overweight or obesity and suspected NAFLD had other causes of liver disease, and none tested positive for autoimmune hepatitis (AIH), reported lead author Toshifumi Yodoshi, MD, PhD, of Cincinnati Children’s Hospital Medical Center, and colleagues.

“Currently, recommended testing of patients with suspected NAFLD includes ruling out the following conditions: AIH, Wilson disease, hemochromatosis, alpha-1 antitrypsin [A1AT] deficiency, viral hepatitis, celiac disease, and thyroid dysfunction,” the investigators wrote in Pediatrics.

Yet evidence supporting this particular battery of tests is scant; just one previous pediatric study has estimated the prevalence of other liver diseases among children with suspected NAFLD. The study showed that the second-most common etiology, after NAFLD, was AIH, at a rate of 4%.

But “the generalizability of these findings is uncertain,” noted Dr. Yodoshi and colleagues, as the study was conducted at one tertiary center in the western United States, among a population that was predominantly Hispanic.

This uncertainty spurred the present study, which was conducted at two pediatric centers: Cincinnati Children’s Hospital Medical Center (2009-2017) and Yale New Haven (Conn.) Children’s Hospital (2012-2017).

The final analysis involved 900 patients aged 18 years or younger with suspected NAFLD based on hepatic steatosis detected via imaging and/or elevated serum aminotransferases. Demographically, a slight majority of the patients were boys (63%), and approximately one-quarter (26%) were Hispanic. Median BMI z score was 2.45, with three out of four patients (76%) exhibiting severe obesity. Out of 900 patients, 358 (40%) underwent liver biopsy, among whom 46% had confirmed nonalcoholic steatohepatitis.

All patients underwent testing to exclude the aforementioned conditions using various diagnostics, revealing that just 2% of the population had etiologies other than NAFLD. Specifically, 11 children had thyroid dysfunction (1.2%), 3 had celiac disease (0.4%), 3 had A1AT deficiency (0.4%), 1 had hemophagocytic lymphohistiocytosis, and 1 had Hodgkin’s lymphoma. None of the children had Wilson disease, hepatitis B or C, or AIH.

Dr. Yodoshi and colleagues highlighted the latter finding, noting that 13% of the patients had autoantibodies for AIH, but “none met composite criteria.” This contrasts with the previous study from 2013, which found an AIH rate of 4%.

“Nonetheless,” the investigators went on, “NAFLD remains a diagnosis of exclusion, and key conditions that require specific treatments must be ruled out in the workup of patients with suspected NAFLD. In the future, the cost-effectiveness of this approach will need to be investigated.”

Interpreting the findings, Francis E. Rushton, MD, of Beaufort (S.C.) Memorial Hospital emphasized the implications for preventive and interventional health care.

“This study showing an absence of etiologies other than obesity in overweight children with NAFLD provides further impetus for pediatricians to work on both preventive and treatment regimens for weight issues,” Dr. Rushton said. “Linking community-based initiatives focused on adequate nutritional support with pediatric clinical support services is critical in solving issues related to overweight in children. Tracking BMI over time and developing healthy habit goals for patients are key parts of clinical interventions.” 

The study was funded by the National Institutes of Health. The investigators reported no conflicts of interest.

Nonalcoholic fatty liver disease (NAFLD) in children is almost always caused by excess body weight, not other etiologies, based on a retrospective analysis of 900 patients.

Just 2% of children with overweight or obesity and suspected NAFLD had other causes of liver disease, and none tested positive for autoimmune hepatitis (AIH), reported lead author Toshifumi Yodoshi, MD, PhD, of Cincinnati Children’s Hospital Medical Center, and colleagues.

“Currently, recommended testing of patients with suspected NAFLD includes ruling out the following conditions: AIH, Wilson disease, hemochromatosis, alpha-1 antitrypsin [A1AT] deficiency, viral hepatitis, celiac disease, and thyroid dysfunction,” the investigators wrote in Pediatrics.

Yet evidence supporting this particular battery of tests is scant; just one previous pediatric study has estimated the prevalence of other liver diseases among children with suspected NAFLD. The study showed that the second-most common etiology, after NAFLD, was AIH, at a rate of 4%.

But “the generalizability of these findings is uncertain,” noted Dr. Yodoshi and colleagues, as the study was conducted at one tertiary center in the western United States, among a population that was predominantly Hispanic.

This uncertainty spurred the present study, which was conducted at two pediatric centers: Cincinnati Children’s Hospital Medical Center (2009-2017) and Yale New Haven (Conn.) Children’s Hospital (2012-2017).

The final analysis involved 900 patients aged 18 years or younger with suspected NAFLD based on hepatic steatosis detected via imaging and/or elevated serum aminotransferases. Demographically, a slight majority of the patients were boys (63%), and approximately one-quarter (26%) were Hispanic. Median BMI z score was 2.45, with three out of four patients (76%) exhibiting severe obesity. Out of 900 patients, 358 (40%) underwent liver biopsy, among whom 46% had confirmed nonalcoholic steatohepatitis.

All patients underwent testing to exclude the aforementioned conditions using various diagnostics, revealing that just 2% of the population had etiologies other than NAFLD. Specifically, 11 children had thyroid dysfunction (1.2%), 3 had celiac disease (0.4%), 3 had A1AT deficiency (0.4%), 1 had hemophagocytic lymphohistiocytosis, and 1 had Hodgkin’s lymphoma. None of the children had Wilson disease, hepatitis B or C, or AIH.

Dr. Yodoshi and colleagues highlighted the latter finding, noting that 13% of the patients had autoantibodies for AIH, but “none met composite criteria.” This contrasts with the previous study from 2013, which found an AIH rate of 4%.
