There is limited information on the clinical and biochemical profile of chronic liver disease due to dual infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. There are variable reports on the severity of liver disease in dual infections. This is important, from clinical and therapeutic point of view. The present study analyzes liver disease in dual infections as compared to HBV and HCV infection present alone. Out of 186 histologically proven non-alcoholic chronic liver disease patients, 30 (16.1%) were serologically diagnosed to be HBV and HCV dual infection (Group A, n=30). The clinical profile of these patients was compared with consecutively seen HBV related (Group B, n=30) and HCV related chronic liver disease (Group C, n=30) patients. Patients with dual infection were further grouped based on predominant HBV or HCV viral activity. Patients with dual infection were younger than those with chronic HCV infection (38.4 +/- 14.4 vs. 45.9 +/- 14.7 years, p < 0.05); with male predominance (p=0.06). Patients with chronic HCV infection more often presented with low-grade fever than dual infection group (60% vs. 30%, p < 0.05). Ascites and variceal bleeding were common presentations of HBV related cirrhosis. Patients with dual infection had significantly more deranged liver functions. The duration of illness was shorter in these patients compared with chronic HCV (2.9 +/- 1.6 vs. 7.3 +/- 1.4 year, p < 0.05). When patients with dual infection were subgrouped on HBV DNA and HCV RNA positivity, there was a tendency for increased biochemical derangement with active HBV infectionity. Our results highlight the fact that patients with HBV and HCV dual infection related chronic liver disease have a more aggressive course. There is a tendency for a more severe liver disease when HBV is active in the dual infection group.
