HCV genotypes distribution of 107 HIV/HCV co-infection individuals in Hunan province / 中华实验和临床病毒学杂志

ABSTRACT

Objective@#To investigate the HCV genotypes distribution of 107 HIV/HCV co-infection individuals in Hunan province.@*Methods@#HCV antibodies positive plasma samples were collected from HIV-1 antibodies positive plasma bank in Hunan Provincial Center for Disease Control and Prevention and carried out the nucleic acid amplification, the PCR products were used for the HCV genotypes analysis.@*Results@#For 107 samples, 77.5%(83/107) were from intravenous drug users and 25.2%(27/107) were underwent spontaneous clearance of HCV. The HCV genotypes distribution varied greatly in different routes of HIV infection. The non-1/non-2 types exceeded 70% in intravenous drug use and unknown route of transmitted infection populations, while the types 1 and 2 mainly occurred in blood transfusion or aphaeresis plasma populations, accounted for 83.3%. There was no statistical significant differences of immune and liver function among the three groups.@*Conclusions@#Among 107 HIV/HCV co-infection individuals in Hunan province, most of them were intravenous drug users and the distribution of HCV genotypes varied greatly in different routes of HIV infection.
