The Clinical Profile of Children With Hepatitis A Infection: An Observational Hospital-Based Study.

Introduction:  Hepatitis A is a frequent form of hepatitis, especially in children. The changing epidemiology of the disease signifies the need for descriptive data concerning the clinical presentation and outcome of hepatitis A in children. The present study describes the clinical and biochemical profile of children with hepatitis A infection from a tertiary care center in the Aurangabad district of Maharashtra in Western India.

Methods:  One hundred patients between one and 18 years of age, presenting with symptoms/signs such as nausea, anorexia, vomiting, jaundice, abdominal pain, tender hepatomegaly, bleeding manifestations, or encephalopathy, were enrolled for the study. Serologically confirmed cases by detecting immunoglobulin M (IgM) antibodies against hepatitis A virus (HAV) were enrolled in the study. A detailed case proforma noted the clinical features and details such as age, gender, area, water supply, socioeconomic status, season, and biochemical parameters.

Results:  Most patients (45%) were among the age group of one to five years. Fever was reported in 96 (96%) patients, abdominal pain in 78 (78%) patients, dark-colored urine in 65 (65%) patients, vomiting in 47 (47%) patients, and anorexia in 63 (63%) patients. Icterus was found in 80 (80%) patients and hepatomegaly in 74 (74%) patients. In 61 (61%) patients, serum total bilirubin level on the first day was 1-4 mg/dL. Sixty-five (65%) patients were using tap water as the water source, and the maximum number of patients (43%) came in August. Most patients belonged to the class IV group (61%) as per the modified Kuppuswamy classification.

Conclusions:  Most patients were 10 years or below, presenting predominantly with fever, abdominal pain, dark-colored urine, vomiting, and anorexia. Icterus and hepatomegaly were found in three-fourths or more of the patients. Around monsoon (June to September), there was the highest frequency of cases, and the socioeconomic status of most of the patients was within lower or upper-lower categories.
