title: [Dynamics of HBV-DNA level in acute hepatitis B].
abstract: OBJECTIVE
  To verify the mechanism of the hepatitis B viral clearance using clinical data.
  
  
  METHODS
  Viral level and HBV marker in serum were analyzed in 12 patients with acute hepatitis B.
  
  
  RESULTS
  The clearance of hepatitis B virus occurred before the patients were hospitalized in 66.7% of patients. The viral level and the A value of HBsAg;HBeAg declined gradually during hospitalization.
  
  
  CONCLUSIONS
  In most of patients with acute hepatitis B in the study, the virus was cleared without destruction of infected cells.
