title: [Elevata prevalenza ma bassa incidenza della infezione da HGV in pazienti con epatite cronica C]
abstract: Objectives To determine 1. The prevalence and incidence of HGV infection in patients with chronic hepatitis C and 2. Its influence on the clinical outcome of chronic hepatitis C. Patients and methods Sixty-five patients with non-parenteral chronic hepatitis C virus infection were investigated for HGV infection using the polymerase chain reaction for HGV-RNA and by detecting serum antibodies against the E2 protein of HGV (anti-E2 antibodies). Results HGV-RNA in serum was found in 12 patients (18.4%) and anti-E2 antibodies in 4 (6.1%). No difference in age, sex, liver histology, basal ALT or ?GT was found between HGV positive and negative cases. Thirty-four patients (6 with HGV-RNA) were followed-up for 4 years; 4 of the 6 lost HGV-RNA, one of whom seroconverted to anti-E2. None of the 28 HGV-RNA negative cases presented HGV infection during the follow-up period. The presence of HGV infection did not influence either basal HCV viremia or the response of HCV to IFN therapy. Conclusions The study demonstrated that HGV had an intense circulation through non-classic parenteral routes, but its impact on HCV replication and liver disease is negligible.
