The incidence of hepatitis delta virus infection in chronic liver diseases in Hungary.

Abstract

A study of hepatitis B and D virus markers in 118 hepatitis B virus seropositive patients suffering from histologically confirmed chronic liver disease is reported. The prevalence of hepatitis delta infection amounted to 13.6%, whereas active hepatitis delta virus replication was proven in 6 of the cases. On the basis of these findings, conclusions--similar to those published earlier--are drawn about the role of hepatitis delta virus in the progression of chronic liver diseases. It is suggested that HBsAg-IgM complex seropositivity in patients suffering from anti-delta positive chronic liver disease supports active hepatitis delta virus replication.
