title: Comparison of clinical, virologic and pathologic features in patients with acute hepatitis B and C.
abstract: OBJECTIVE
  The clinical outcomes of adult-acquired acute infection of hepatitis C virus (HCV) and hepatitis B virus (HBV) are quite different. In order to compare the clinical, biochemical, virologic and pathologic pictures in these two groups of patients, we enrolled 22 adult patients with acute hepatitis C and 16 adult patients with acute hepatitis B, on whom liver biopsies were performed within 3 months of acute onset of the illness.
  
  
  RESULTS
  The results showed that a significantly younger age, a higher ratio of the clinical symptoms of jaundice, nausea, vomiting, and poor appetite, a higher mean serum level of alanine transaminase, aspartate transaminase, and total bilirubin were present in patients with acute hepatitis B patients than in those with acute hepatitis C (P < 0.05). There was a significantly higher degree of periportal inflammation and total necro-inflammatory activity in the acute hepatitis B patients (P = 0.002 and 0.049, respectively). Fifteen (68.2%) of the 22 patients with acute hepatitis C had detectable serum HCV-RNA, but only two (14.3%) of the 14 tested patients with acute hepatitis B had detectable serum HBV-DNA, detected by using the branched DNA signal amplification assay. Eighteen (82%) of the 22 acute hepatitis C patients and none of the 16 acute hepatitis B patients progressed into a chronic hepatitis stage (P < 0.001).
  
  
  CONCLUSIONS
  The manifestations of mild clinical symptoms, lower mean serum transaminases and bilirubin levels, a lesser degree of histological periportal necroinflammation, and more patients with a high circulatory viral load among the acute hepatitis C patients, may lead to more of that group developing chronicity than patients with acute hepatitis B.
