[Clinical characteristics of acute non A to G hepatitis caring TTV-DNA]

We measured TTV-DNA using polymerase chain reaction method in twenty seven patients with acute non A to G hepatitis and 139 patients with known types of acute hepatitis. TTV-DNA was detected in 40.7% in the former and in 36.7% in the latter, which was not significantly different. In acute non A to G hepatitis, TTV-DNA was more common in the male and in patient with more advanced age, however, no remarkable difference was noted concerning clinical characteristics according to the existence of TTV. Therefore TTV does not seem to play a causative role in pathogenesis of acute non A to G hepatitis.
