Clinical features of HGV infection as a novel virus infection have not yet been clarified enough. We studied the implication of HGV in the activity of hepatitis and the sensitivity of HGV to IFN. We treated 10 HGV RNA positive patients with chronic hepatitis C with IFN. HGV RNA was identified in serum by RT-PCR method using the primer derived from the base sequences of the NS5 region of HGV genome. HGV RNA became negative in the all of 10 patients during IFN treatment, but returned to be positive again in the all patients after the completion of IFN treatment. In 5 of 10 patients, HCV RNA became persistently negative. In 3 of these 5 patients, ALT was continuously normal and hepatitis subsided biochemically and clinically after IFN treatment. We assume that HGV is sensitive to IFN, but could not be implicated in hepatitis or liver damage.
