ABSTRACT
This study was carried out to determine the presence of markers of hepatitis viruses in patients with acute liver disease. Coinfection of HAV, HBV, HCV, and HEV was studied. Sera from 306 patients with a clinical diagnosis of acute liver disease were tested for the presence of anti-HAV antibody, HBsAg, anti-HBc antibody, anti-HBs antibody, anti-HCV antibody and IgM anti-HEV antibody by ELISA. Liver function tests were correlated with the presence of infection. Of the 306 cases, 7 (2.3%) had IgM anti-HAV, 9 (2.9%) had IgM anti-HBc, 37 (12.1%) had HBsAg, 84 (27.4%) had anti-HBs, 10 (3.3%) were HCV infected and 63 (20.6%) had IgM anti-HEV. There was no significant difference in the clinical and liver function profiles of infected and uninfected patients. Similarly, no difference was observed in cases coinfected with more than one virus compared with those infected with a single pathogen. HEV had the highest prevalence amongst our cases. There was no difference in the clinical profiles of patients with non-A, non-B, non-C, non-E hepatitis by antibody assays and testing for viremia could be helpful in making the correct diagnosis.
