title: [Study of superinfection of HBV and HCV].
abstract: OBJECTIVE
  To understand the situation in hepatitis B patients coinciding with HCV and to explore its influence on HCV on the replication of HBV.
  
  
  METHODS
  Using ELISA, 712 hepatitis B patients were tested for serum anti-HCV and markers of HBV.
  
  
  RESULTS
  Of the 712 patients, anti-HCV positive rate was 14.47% with the highest 48.98% in patients with severe hepatitis and the lowest 3.25% in patients with acute hepatitis. Markedly different anti-HCV positive rates (P < 0.001) in patients of different clinical stages were discovered. The more severe the case with longer the course, the higher the anti-HCV positive rates. In patients with superinfection of HBV and HCV, serum HBsAg, HBeAg and anti-HBcIgM positive rates were lower than those in patients with hepatitis B (P < 0.001, P < 0.001 and P < 0.05) but the anti-HBe positive rates were higher. All the differences showed an obvious statistical significance.
  
  
  CONCLUSIONS
  Hepatitis B coinciding with HCV infection is responsible for the deterioration of the disease and towards its formation of its chronic phase as well as for the inhibition of HBV replication.
