Hepatitis viruses in Kathmandu, Nepal: hospital-based study.

OBJECTIVE

The objective of this study was to see the aetiology and outcome of sporadic acute viral hepatitis (AVH) in Kathmandu, Nepal.

RESULTS

Among 210 patients, 94 (45%) were male and 116 (55%) were female. Mean age was 30 years. 52 (24.7%) out of 210 were positive for either of the hepatitis virus infection. Major causative agent for AVH among hepatitis positive patients were hepatitis E virus (HEV) in 36 (69.2%), followed by hepatitis A virus (HAV) 8 (15.3%), hepatitis B virus (HBV) 7 (13.4%) and hepatitis C virus (HCV) 1 (1.9%). The 158 (75.3%) patient were negative for all hepatitis viral markers. Co-infections with more than one virus were found in 4 (7.6%) patients. All liver-specific enzymes including bilirubin increased in hepatitis-infected patients. We found large number circulation of HEV in Kathmandu, Nepal, indicating that this region is endemic for hepatitis virus infection.
