TTV infection and its relation to serum transaminases in apparently healthy blood donors and in patients with clotting disorders who have been investigated previously for hepatitis C virus and GBV-C/HGV infection in Belgium.

A novel DNA virus, TT virus (TTV), has been proposed as a possible etiologic agent for non A-E hepatitis. The aim of the present study was to determine the prevalence of TTV infection using PCR in healthy blood donors and in patients with clotting disorders who have been investigated previously for GBV-C/HGV and HCV infection in Belgium. In this study, PCR using primers proposed by Takahashi et al.

Anti-hepatitis G E2 antibody detection and its relation to serum HGV-RNA in patients with clotting disorders: high prevalence of HGV infection and spontaneous remission.

In a previous study, we have determined the prevalence of serum HGV-RNA in patients with congenital clotting disorders. Twenty-six (15%) of 175 patients investigated were serum HGV-RNA positive. In addition, HGV-RNA was detectable in peripheral blood mononuclear cells (PBMC) in ten percent of the cases, three of these patients were serum HGV-RNA negative.

High prevalence of hepatitis G virus infection compared with hepatitis C virus infection in patients undergoing chronic hemodialysis.

A recently discovered non-A-E hepatitis virus has been designated as hepatitis G virus (HGV) and identified as a new member of the Flaviviridae family. Infection by this virus is thought to be associated with blood-borne hepatitis and usually in the presence of hepatitis C or hepatitis B virus (HBV) infection. In this study, the presence of HGV-RNA in serum or plasma and the prevalence of antibodies against an HGV envelope protein (E2) were investigated in patients undergoing chronic hemodialysis using a sensitive reverse-transcriptase polymerase chain reaction and an enzyme-linked immunosorbent assay, respectively.
