Abstract
The presence of hepatitis B virus DNA in serum was determined in 57 unselected patients during the course from acute to chronic hepatitis B infection. Forty–six (81%) patients were hepatitis B virus DNA–positive in the first available serum sample. Generally, hepatitis B virus DNA was cleared before or at the same time as HBeAg, but in two patients (4%), hepatitis B virus DNA could be demonstrated after HBeAg clearance. One of the latter patients had hepatitis B virus DNA in the presence of anti–HBe. Both patients became hepatitis B virus DNA–negative. Seven of the hepatitis B virus DNA–positive patients received long–term treatment with prednisone, and three of them continued to be hepatitis B virus DNA positive for more than 10 years. Among the untreated patients hepatitis B virus DNA could be detected for up to 7 years, and 10 patients were hepatitis B virus DNA–positive for three years or more. Twenty–four patients (42%) showed serological signs of delta agent infection. Hepatitis B virus DNA clearance was observed in a significantly higher proportion (87%) of delta–infected patients as compared to patients with no delta infection (45%) (p < 0.05). In addition patients with delta infection had a significantly increased hepatitis B virus DNA clearance rate as compared to patients without delta markers in their serum (p < 0.01). In one (8%) delta–infected patient, hepatitis B virus DNA clearance was followed by a fall in transaminases into the normal range as opposed to results in 86% of patients with pure hepatitis B (p < 0.002).
