Clinical and Epidemiological Spectrum of Acute Viral Hepatitis Due to Hepatitis A and E in Children: A Descriptive, Cross-Sectional, Hospital-Based Study

Objective: Acute viral hepatitis (AVH) in children is a serious and major public health concern globally and in developing countries such as Pakistan. We conducted this study to determine the clinical and epidemiological spectrum of AVH due to hepatitis A virus (HAV) and hepatitis E virus (HEV) infection in children. Methodology: This cross-sectional study was conducted at the Pediatric Medicine Department of a tertiary care hospital from February 20, 2020, to February 20, 2022. A total of 200 children 1-12 years of age who presented with symptoms and signs of AVH were enrolled. Demographic and clinical characteristics were noted, and venous blood was drawn for the assessment of HAV IgM and HEV IgM using an enzyme-linked immunosorbent assay (ELISA). Descriptive statistics are run, and the results are presented as tables. Results: Of the children, 75% were diagnosed with acute HAV infection. The median duration of illness was six days (range: 2-21 days). The most common age group affected was 6-10 years (43.5%), of which 56.5% were males. Most of the children belonged to low and middle socioeconomic status (86.5%), and 41.5% consumed underground water for drinking. Fever was the most common symptom, followed by appetite loss and yellow discoloration of urine. Alanine aminotransferase (ALT) was significantly high in HEV compared to HAV infection (2060.2 +/- 1036.7 versus 1730.7 +/- 957.5 IU/L) (P=0.04). Conclusion: Acute HAV was more prevalent. Those who are male, 6-10 years of age, from lower and middle socioeconomic status, and using underground drinking water were more affected by acute viral hepatitis. The clinical and biochemical presentation of HAV and HEV did not differ significantly.
