Abstract: Objective To investigate the ratio of hepatitis C virus (HCV) coinfection and the impact of HCV co-infection on CD4+T cell counts in human immunodeficiency virus 1 (HIV-1)-infected patients. Methods A crosssectional study was performed among HIV-1infected patients for assessment of HCV co-infection determination with serology and nucleic acid test in Dali Yunnan. Results Among 526 HIV-1infected patients, the injecting drug users accounted for 94.3%, and the others were infected through sex. The percentage of anti HCVIgG positive was 86.9%(457/526), and the positive accordant rate of HCV RNA and anti HCV-IgG was 78.3%. However,HCV RNA >1 000 IU/mL was detected in 24 patients out of 69 anti HCV-IgG negative patients. As for HCV nucleic acid test, the detection rate of HCV coinfection increased 4.6% (24/526). The ratio of HCV co-infection was 91.4%. The CD4+T cell counts among single HIV-1 infection were significantly higher than those among HCV co-infection. Conclusions The ratio of HIV-1/HCV infection is high in highrisk areas or population, and the determination of HCV during screening HIV-1 infection may help for the early diagnosis and treatment of HCV and decrease the effect of HIV-1 infection patients.
