Liver cirrhosis and hepatocellular carcinoma are known sequelae of chronic hepatitis. Early diagnosis and treatment of chronic hepatitis could delay or even abort progression to terminal liver disease.Prospective study of 70 consecutive patients with features of early liver disease or discovered with HBsAg (or anti-HCV) during pre-employment and/ or pre-donation screening at Ile-Ife, Nigeria. All the patients had liver biopsy and the histology evaluated with the Knodell Histological Activity Index.Fifty-three patients had symptomatic disease (M: F ratio, 1.5:1) while 17 were asymptomatic (M: F ratio, 3:1). The mean ages were 49.04 (SD+/-16.78) and 29.82 (SD+/-6.13) for the symptomatic and the asymptomatic patients respectively (P0.005). Major symptoms were right upper abdominal pain (68%), weight loss (51%) and fatigue (41.5%). Alcohol consumption was significantly related to symptomatic chronic hepatitis (P0.01). Over 50 % of patients with asymptomatic chronic hepatitis had abnormal liver scan and liver function tests. All the asymptomatic cases and 77.4 % of the symptomatic group had HBsAg while only 1 patient (symptomatic) was anti-HCV positive. On liver histology, all the patients with asymptomatic chronic hepatitis had a Knodell score ofor = 8 and none had fibrosis. Over half of the symptomatic patients had a Knodell score ofor = 9 (56.6%) and stage 2 or 3 fibrosis (51 %).Asymptomatic chronic hepatitis patients tend to be younger and of the male sex. Symptomatic chronic hepatitis may signal the onset of significant fibrosis and alcohol abuse may accelerate this process. Serum ALT and liver scan are useful initial screening tests for asymptomatic patients with hepatitis B or C viral markers.
