No association between GB virus C infection and disease progression in HIV-2-infected patients from the French ANRS HIV-2 cohort.

ABSTRACT

Out of 183 HIV-2-infected patients tested in the ANRS CO8 HIV-2 cohort, 69 were exposed to GB virus C (GBV-C), yielding a prevalence of 38% (95% CI 30.7, 45.2). There was no significant difference between the CD4 cell count and HIV-2-RNA plasma viral load in patients exposed and not exposed to GBV-C. After adjusting for age and CD4 cell count, co-infection with GBV-C was not associated with clinical progression (hazard ratio 0.78; 95% CI 0.24-2.56, 16 clinical events).
