title: Serum HBV-DNA (hepatitis B virus DNA) in acute and chronic hepatitis B infection.
abstract: HBV DNA was measured in the sera of 69 patients with hepatitis B virus infections. Sixteen patients had acute hepatitis B, 24 had chronic active hepatitis (CAH), 6 had chronic persistent hepatitis (CPH), 5 had cirrhosis without CAH and 18 were asymptomatic HBsAg carriers. In patients with acute hepatitis B who recovered, HBV DNA was present in the serum transiently early in the illness. HBV DNA persisted in the serum in the two patients who developed chronic hepatitis. Sera of 23 of 24 patients with CAH were persistently positive for HBV DNA. There was no relationship between the quantity of HBV DNA in the serum and the histological intensity of activity. Thirteen of the 24 patients with CAH had histological evidence of cirrhosis in addition to CAH and HBV DNA was detected in the sera of all 13. The sera of 2 of 6 patients with CPH were positive for HBV DNA. In one it was positive only where there was clinical evidence of reactivation of HBV infection. The other patient subsequently developed CAH. Sera of 5 patients with established HBsAg positive cirrhosis but without evidence of CAH were negative for HBV DNA. Two of these patients had hepatocellular carcinoma. Sera of 18 asymptomatic anti-HBe positive carriers with normal ALT were negative for HBV DNA. HBeAg and HBV DNA were not always found in the serum together. In acute hepatitis 5 patients with HBV DNA in the serum were HBeAg positive, but in 6 patients the sera were HBeAg positive inthe absenceof HBV DNA.
