COVID-19 among infants: key clinical features and remaining controversies

Nevio Cimolai

Clin Exp Pediatr. 2024;67(1):1-16. Published online November 27, 2023

· Clinical studies of coronavirus disease 2019 (COVID-19) in infants should be supported by rigorous laboratory diagnostic criteria.
· Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads to infants similarly to other viral respiratory infections.
· Among infants ≤1 year of age beyond the immediate postpartum period, COVID-19 is relatively mild, but even the low risk of severe disease requires prevention.
· Comorbidities increase infection vulnerability and complications in infants.
· Clinical and laboratory data do not sufficiently distinguish COVID-19 from other respiratory viral infections.
· Coinfection with SARS-CoV-2 is uncommon among infants.
· Unique infection sequelae, including multi-inflammatory syndrome in children and neonates and long COVID require further study and refinement of diagnostic criteria.
· Infection control standards applied to mother-infant dyads should be tempered by standard preventive strategies, maternal input, accommodation potential, and overall safety.
· Maternal vaccination prevents disease in early infancy.

X-linked hypophosphatemic rickets: from diagnosis to management

Eujin Park, Hee Gyung Kang

Clin Exp Pediatr. 2024;67(1):17-25. Published online June 14, 2023

· X-linked hypophosphatemia (XLH), the most common cause of hypophosphatemic rickets, affects 1/20,000 people.
· XLH is caused by a loss-of-function mutation of the PHEX gene.
· Its main pathogenesis is elevated fibroblast growth factor-23 (FGF23) level.
· Burosumab, an FGF23 inhibitor, was developed in the early 2000s.
· Burosumab was approved in Korea in 2020 for XLH patients aged 1+ years with radiographic evidence of bone disease.

· Primary pediatricians should play a key role in the diagnosis and treatment of attention-deficit/hyperactivity disorder (ADHD).
· The Diagnostic and Statistical Manual of Mental Disorders, fifth edition, has lowered the diagnostic threshold for older teens and adults and a comorbid diagnosis with autism is now allowed.
· The American Academy of Pediatrics had added recommendation-related comorbid conditions in its guideline and the Society of Developmental and Behavioral Pediatrics recently developed a complex ADHD guideline.
· The European ADHD Guideline Group recently developed a guideline for managing ADHD during the coronavirus disease 2019 pandemic.

Clinical considerations and practical issues of kidney complications in children after COVID-19 infection or vaccination

Jiwon Jung, Joo Hoon Lee

Clin Exp Pediatr. 2024;67(1):35-36. Published online November 17, 2023

· The proper monitoring for and treatment of coronavirus disease 2019 (COVID-19)-induced acute kidney injury, which is common in critically ill children, are recommended.
· Glomerulopathy associated with COVID-19 or its vaccination has been reported, and the overall clinical course is similar to that of non-COVID-19-associated diseases.
· Additional COVID-19 vaccinations are recommended; however, careful and individualized decisions should be made in patients with COVID-19- or vaccination-associated glomerulopathy.

Relationship between inflammatory biomarkers and insulin resistance in excess-weight Latin children

Question: What is the prevalence of insulin resistance (IR) in excess-weight Latin children, and can proinflammatory biomarkers predict it?
Finding: IR prevalence was elevated and tumor necrosis factor- α, interleukin-6, monocyte chemoattractant protein- 1, soluble CD40 ligand, and high-sensitivity C-reactive protein levels were increased in excess-weight Latin children. However, none predicted IR status.
Meaning: These inflammatory biomarkers were unable to predict IR status. Therefore, further investigations are necessary.

Effectiveness of Helmet therapy for infants with moderate to severe positional plagiocephaly

Jeongho Kim, Jina Kim, Kyu Young Chae

Clin Exp Pediatr. 2024;67(1):46-53. Published online December 5, 2023

Question: Is helmet therapy effective for positional plagiocephaly? What factors influence helmet therapy efficacy for positional plagiocephaly?
Finding: Helmet therapy is effective for infants with moderate to severe positional plagiocephaly, and its effectiveness is influenced by age at treatment initiation, severity of head asymmetry, and daily duration of helmet wear.
Meaning: Pediatricians should initiate helmet therapy for positional plagiocephaly sooner, ideally before 9 months of age, to maximize treatment efficacy.
