4 Washington D.C., USA, 22-27 July 2012www.aids2012.org Background It remains unknown the associations of HCV clearance in HIV-positive Chinese IDUs. Less is known about whether and how HCV genotypes affect its clearance.

5 HIV-HCV co-infection prevalence among IDUs in China 0 Yunnan (46.3%) Myanmar Thailand Laos Vietnam Xinjiang (36.2%)

6 Washington D.C., USA, 22-27 July 2012www.aids2012.org Study Objectives To determine the prevalence of HCV infection, spontaneous clearance and genotype distribution among HIV-positive IDUs from Yunnan, a region with the highest HIV-HCV co-infection prevalence in China. To search for factors that may affect the clearance of HCV and whether HCV genotypes could exert different influences on those factors.

7 HIV-positive IDUs were recruited in Yunnan Province ( Dali CDC, Compulsory detoxification, Labor camp ) Interview Sociodemographic information, high-risk behaviors and history of HIV-infection and medication Blood collection CD4 T cell count (FACSAria flow cytometry; BD Bioscience), ALT,TB Anti-HCV Ab (ELISA; Kehua Company) HBsAb, HBsAg, HBeAg, HBeAb, HBcAb (ELISA; Wantai Company) HCV viral load (Realtime-PCR; PG Biotech Company) HCV genotyping (5’NCR/ NS5B/ E1–E2; ABI Prism 3100 genetic analyzer) Data analysis SPSS software (version 17.0)

15 Washington D.C., USA, 22-27 July 2012www.aids2012.org Conclusions The prevalence of HCV was 91.1% among HIV-infected IDUs, the spontaneous clearance rate was 21.4%. Our results suggested that the reserved host immune function (high CD4+T counts) and HBV co-infection (chronic HBV) could improve HCV clearance in HIV-infected IDUs whereas the damage in liver (high level of ALT) was associated with the non-clearance of HCV. We demonstrated that the clearance of different HCV genotypes might be facilitated by different factors. HBV chronic infection seemed to facilitate HCV genotype 3 clearance but not genotype 1 and 6. Further cohort studies are needed to determine the influences of HCV genotypes and HBV co-infection on the HCV spontaneous clearance.
