Hepatitis C virus (HCV) co-infection with human immunodefi ciency virus (HIV) is assuming greater signifi cance in recent years across the globe. Genotyping of HCV is important to augment appropriate antiviral therapy during HCV/HIV co-infection. Present study was therefore, intended to determine the dominant genotype(s) of HCV in HCV/HIV co-infected cases belonging to the metropolitan city of Delhi which is one of the most thickly populated places with diverse communities in the Asian sub-continent. Th irty-six cases of HCV (20 HCV/HIV co-infected and 16 HCV mono-infected) were included in the study. HCV RNA extraction, cDNA synthesis, amplifi cation of the 5?UTR followed by nucleotide sequence determination and phylogenetic analysis was carried out. Results revealed exclusive dominance of HCV genotype 1 in HCV/HIV co-infected cases while genotype 3 in HCV mono-infected cases. Comparative review of our fi ndings with other scanty reports from rest of the world suggests dominant co-existence of HCV-genotype-1 both with Afro-Asian (subtype C) and Euro- American subtypes (A/B) of HIV-1. Prognosis is worse in HCV genotype 1 patients co-infected with HIV. Th is is especially relevant in countries like India where a large population is infected with HCV/HIV co-infection and HCV genotype 1 is prevalent. Th e HCV genotype 1 has been reported to be associated more oft en with a rapid progression to AIDS and death than other genotypes. HIV co-infected patients with HCV genotype 1 had more liver related deaths than patients co-infected with other genotype. Th ese facts indicate that HCV/HIV co-infection appears to have some link or relation with HCV genotype 1.
