Prevalence and risk factors for hepatitis c virus co-infection among human immunodeficiency virus-infected patients and effect of hepatitis c virus infection on acquired immunodeficiency syndrome cases at baseline.

Background: Hepatitis C virus (HCV) co-infection with human immunodeficiency virus (HIV) exists as both viruses have the common routes of transmission. HIV infection has adverse effect on the natural history of HCV infection; however, the effect of HCV infection on the natural history of HIV infection is unclear.

Materials And Methods: This study was cross-sectional comprising of treatment-naïve adult HIV-infected patients attending clinics at Usmanu Danfodiyo University Teaching Hospital, Sokoto and Specialist Hospital Sokoto. The study participants were screened for HCV anti]body and assayed for transaminases and CD4 T-lymphocytes count levels. The symptoms of acquired immunodeficiency syndrome (AIDS)-defining illnesses were asked among the study participants. The questionnaire was used for the collection of data, and SPSS software version 20 was used for the analysis of data. Student's t-tests, Pearson's, Chi-square, and Fisher's exact tests were used for the statistical analysis, and P < 0.05 was considered statistically significant.

Results: The prevalence of HIV/HCV co-infection was 20.6%. Self-intravenous drugs usage was not statistically significant (P = 0.210). HIV mono-infected patients had significantly lower alanine aminotransferase levels compared to HIV/HCV co-infected study participants (P = 0.048). AIDS status at the baseline was comparable between HIV mono-infected and HIV/HCV co-infected study participants. (P = 0.227; 0.200; 0.130).

Conclusion: Moderately high prevalence of HIV/HCV co-infection was observed in the current study. HCV co-infection had no effect on AIDS status at baseline. There is a need for routine screening of HCV infection in HIV-infected individuals.
