Hepatitis-G virus infection in multi-transfused patients and intravenous drug abusers: New Delhi experience.

Hepatitis G virus (HGV) is a newly described virus that has been implicated in transfusion-associated hepatitis. HGV-RNA indicating current infection has frequently been isolated from the sera of multi-transfused patients (MTPs) and that of intravenous drug abusers (IVDAs). There is insufficient data on its prevalence among these high-risk groups in India. Hence this study was designed to evaluate the prevalence of HGV infection in MTPs and IVDAs. A total of 90 (57 males and 33 females) MTPs and 65 (44 males and 21 females) IVDAs were recruited in the study. Patients' sera were tested for liver function profile, HGV-RNA, anti-HCV, HCV-RNA, HBsAg, and HBV-DNA. HGV-RNA was detected in 17.7% (16/90) MTPs and 23% (15/65) IVDAs, and 93.5% of our HGV-positive patients were found to be co-infected with either HBV (38.7%) or HCV (74.1%). The sero-prevalence of HBV was found out to be 40% and 21.5%, respectively, in the two groups, that of HCV was 32.2% and 32.3%, respectively, and dual infection was observed in 15.5% and 10.7% of the subjects, respectively. There were no statistically significant differences between the clinical, biochemical, and serological profiles of HGV-positive and negative patients. The prevalence of HGV infection in these high-risk groups is significantly higher than in controls. HGV is found to be co-infected more frequently with HCV than with HBV.
