Hepatitis B in Pediatric Population: Observational Retrospective Study in Romania

Abstract

Hepatitis B virus (HBV) is a frequent cause of chronic hepatitis worldwide, with an estimated 5.6 million children under 5 years being infected. In Romania, there are no available epidemiology reports on large cohorts in children. We aimed to assess the profile of pediatric chronic HBV infection in southern Romania. We conducted an observational retrospective study on 506 HBV-infected children. Based on alaninaminotransferase (ALT), HBV serology and viremia, we identified four states of the disease. We correlated age, gender, household HBV infection, coinfection with other viruses and laboratory parameters. Most patients were in a positive HBV envelope antigen (HBeAg) immune-active state (65.4%). Age at diagnosis was significantly lower for those with household infection (p p = 0.780). ALT values were higher in patients with hepatitis D virus (HDV)-associated infection (p p p = 0.21). Most of the patients are in an immune-active state (high ALT, high viremia). The percentages of HBV- and HDV-associated infections are high, but lower than the reported prevalence in Romania in the general population.
