title: [Significance of detecting HBV-DNA by the fluorescence quantitative PCR].
abstract: BACKGROUND
  To study the correlativity between HBV-DNA and the markers of hepatitis B virus infection and different clinical types of hepatitis B.
  
  
  METHODS
  The fluorescence quantitation (FQ) of HBV-DNA of 105 patients with hepatitis B was performed by PCR, and the correlativity between the fluorescence quantitation of HBV-DNA and the markers of hepatitis B virus and different clinical types of hepatitis B was analyzed.
  
  
  RESULTS
  Ninety-seven percent of the patients were found HBsAg(+), HBeAg(+), HBcAb(+); 75% were HBsAg(+), HBeAb(+), HBcAb(+); 60% were HBsAg(+), HBcAb(+); 40% were HBsAg(+); in HBsAb(+), HBeAb(+), HBcAb(+) (or both HBsAb and HBcAb were positive) group the HBV DNA was undetectable. The analysis indicated that there was a significant difference among different groups (P less than 0.05).HBV-DNA was detected in 72.2% in acute hepatitis B group, in 75% of chronic hepatitis B group, and in 70% of cases of liver cirrhosis with hepatitis B group. The analysis indicated that there was no significant difference among the different clinical types of hepatitis (P greater than 0.05).
  
  
  CONCLUSIONS
  The levels of viral replication were not correlated with different clinical types of hepatitis B; the concentration of HBV-DNA in serum was related to hepatitis B antigen.
