Covid-19 Associated Hepatitis in Children (Cah-C) during the Rise of Delta Variant in India: A New Covid-19 Complication or a Superinfection

ABSTRACT

Intro While the pediatric population has largely remained free of severe COVID- 19, in some situations SARS-CoV-2 infection has been associated with complications like Multiple Inflammatory Syndrome in children (MIS-C). Recently, cases of hepatitis in children have caused tremendous worry across the globe, we describe a unique presentation from 2021, subsequent to asymptomatic infection of SARS-CoV-2, a unique form of severe hepatitis designated by us as COVID-19 Associated Hepatitis in Children (CAH-C). The clinical presentations, temporal association, and viral parameters of CAH-C cases, and contrast to that of MIS-C cases are presented here. Method(s) As a retrospective and follow-up case-control study we reviewed all children within 14 years presenting with "sudden onset of hepatitis, elevated transaminases, non-obstructive jaundice. After performing all routine tests among them, those lacking marked inflammatory responses and without evidence of (a) other known causes of acute hepatitis (A-E) or previous underlying liver disease, and (b) multi-system involvement", being unique such cases were classified as CAH-C, and are described here. Finding(s) Among 475 children who tested positive, 37/47 cases had features of CAH-C, having symptoms of hepatitis only, with un-elevated inflammatory markers, 100% positivity for SARS-CoV-2 antibodies, and uneventful recovery. The remaining 10/47 having MIS-C had protracted illness, multiple system involvement, required admission to critical care, and a mortality rate of 30%. Among controls, only 26/50 (52%) had SARS-CoV-2 antibodies. Discussion(s) During the pandemic, various COVID-19 complications have been observed posing safety concerns, where our study identified a unique form of acute hepatitis in children designated as CAH-C. Conclusion(s) With the emergence of newer variants, including the Delta variant which predominated the second wave of infections in India and spread worldwide with changing presentations and complications, CAH-C is such new entity in children. It needs early identification and differentiation from other emerging syndromes during the ongoing pandemic for preventing adversities through timely intervention.Copyright © 2023
