Amrita Pattanaik, Prasad Varamballi, Srilatha Marate, Sushma Bhandarkar B., Shrikiran Aroor, Somashekar A.R., Suchetha S. Rao, Chiranjay Mukhopadhyay

Clin Exp Pediatr. 2026;69(9):726-732. Published online August 19, 2026

Question: Do serum soluble C5b-9 (sC5b-9) levels change following immunomodulatory therapy in children with multisystem inflammatory syndrome in children (MIS- C)?
Finding: In this longitudinal multicentric study of 100 children with MIS-C, serum sC5b-9 concentrations significantly decreased following treatment, although some patients showed persistently elevated levels at discharge.
Meaning: Serial sC5b-9 measurements may indicate treatment-associated immune activity and recovery in MIS-C.

Distinct age-dependent phenotypes of abnormal liver function tests derived from national Emergency Department data

Dong-Uk Kim, Shinjie Choi, Yeji Kim, Lia Kim, Jung Ok Shim, Jin Soo Moon, Jong Woo Hahn, Hye Ran Yang, Ju Young Chang, Jae Sung Ko

Clin Exp Pediatr. 2026;69(7):563-571. Published online May 14, 2026

Question: What are the clinical phenotypes and pathogen associations of pediatric and adult Emergency Department visits for abnormal liver function tests?
Finding: Pediatric visits showed fever-predominant profiles with temporal correlations with respiratory viruses, whereas adult visits revealed population-level temporal associations between enteric pathogens and infectious gastroenteritis, upper gastrointestinal disorders, and metabolic comorbidity clustering.
Meaning: These findings provide novel population-level evidence of age-specific pathogen associations and support distinct age-stratified clinical diagnostics.

Clin Exp Pediatr. 2026;69(6):508-517. Published online April 10, 2026

Question: How do body mass index (BMI) and metabolic markers change over time in severely obese Korean children and adolescents receiving only lifestyle modifications?
Finding: Among 124 participants, BMI z scores decreased modestly over 2.6 years, primarily in younger prepubertal boys. However, most remained severely obese, with minimal improvement in body composition or metabolic markers.
Meaning: Lifestyle interventions alone have limited efficacy for severe pediatric obesity. Early and more intensive treatments are required.

Question: Does atrial septal defect (ASD) physiology affect postrepair mitral valve growth in patients with coarctation of the aorta or an interrupted aortic arch?
Finding: Mitral valve growth occurred after biventricular repair but not single-ventricle palliation, particularly in patients with small valves and low ASD pressure gradients.
Meaning: The ASD pressure gradient determines mitral valve growth and should guide surgical strategies in patients with borderline hypoplastic left heart syndrome.

· Most sacral dimples are benign, but atypical features may indicate occult spinal dysraphism.
· Simple dimples meeting strict criteria require no imaging, whereas atypical dimples require targeted ultrasonography or magnetic resonance imaging.
· The early diagnosis and surgical management of highrisk cases prevents irreversible neurological, orthopedic, and urological deficits.

Less invasive surfactant administration versus intubation-surfactant-extubation: a single-center retrospective study

C.S. Jithin, A. Nalina, A. Shashidhar, P.N. Suman Rao

Clin Exp Pediatr. 2025;68(12):991-997. Published online October 2, 2025

Question: Does less invasive surfactant administration (LISA) (vs. intubation-surfactant-extubation) improve clinical outcomes in preterm infants with respiratory distress syndrome?
Finding: LISA significantly reduced intubation and invasive mechanical ventilation needs within the first 72 hours and shortened the overall invasive respiratory support duration without increasing other morbidities.
Meaning: LISA is a less invasive and safer surfactant delivery alternative. Larger multicenter trials are needed to confirm its long-term safety and efficacy, especially in low- and middle-income countries.

Question: Can cytokine levels predict low cardiac output syndrome (LCOS) in children post–cardiopulmonary bypass?
Finding: Elevated interleukin (IL)-6, IL-8, and tumor necrosis factor-α levels were associated with LCOS, with an increase in IL-8 of >56 pg/mL from baseline to immediately postoperative being the strongest predictor.
Meaning: Monitoring immediately postoperative IL-8 levels may help identify pediatric patients at risk of LCOS, enabling timely interventions to improve outcomes.

Web of Science 1 Crossref 1

Question: Although children with postacute sequelae of coronavirus disease 2019 (PASC) may experience persistent symptoms that affect their quality of life (QoL), a screening tool for identifying high-risk children is lacking.
Finding: Kinder Lebensqualität fragebogen (KINDL) and Children's Somatic Symptom Inventory-24 (CSSI-24) were significantly correlated. An optimal KINDL cutoff score (74.75) detected those at high risk of a reduced QoL.
Meaning: Integrating KINDL and CSSI-24 into routine pediatric outpatient care may enable timely identification and interventions for children at risk of PASC-related impairments.

Web of Science 1 Crossref 1

Question: Vasovagal syncope (VVS) and postural orthostatic tachycardia syndrome (POTS) are representative forms of neurally mediated syncope. What influences the occurrence of each?

Question: Do macrophage migration-inhibitory factor (MIF) and growth differentiation factor-15 (GDF-15) levels and their gene polymorphisms affect RDS among preterm babies?
Finding: Significantly higher serum MIF and GDF-15 levels were observed in patients with severe respiratory distress syndrome (RDS). The mutant G- and C-alleles of GDF-15 rs4808793 C>G single nucleotide polymorphism (SNP) and MIF rs755622 G>C SNP were present at significantly higher frequencies in preterm neonates with RDS.
Meaning: MIF and GDF-15 play a significant role in neonatal RDS and its severity.

Web of Science 4 Crossref 4

Question: Could hematopoietic stem cell transplantation (HSCT) be an alternative to enzyme replacement therapy (ERT) for type VI mucopolysaccharidosis (MPS VI)?
Finding: HSCT is generally not offered due to reports of high toxicity and mortality. However, we detected fewer complications and graft-versus-host disease cases and no deaths with HSCT.
Meaning: HSCT is both less expensive than ERT and permanent; thus, it should be considered an alternative treatment for MPS VI.
