Abstract

The influence of HIV coinfection on plasma hepatitis C virus (HCV) RNA load has not been reliably evaluated. We analyzed plasma HCV RNA load in 396 HCV-monoinfected and 467 HIV/HCV-coinfected patients. Median HCV RNA concentrations (interquartile range) in HCV-monoinfected patients were 5.88 (5.3-6.2) log(10)IU/mL versus 5.96 (5.6-6.5) log(10)IU/mL in HIV/HCV-coinfected individuals (p=0.033) as determined with the Cobas Amplicor Test and 6.06 (5.4-5.7) log(10)IU/mL versus 6.3 (5.5-6.9) log(10)IU/mL (p=0.026) using the Cobas TaqMan System. The plasma HCV RNA load in patients with HIV infection and undetectable plasmatic HIV RNA was similar to that observed in HCV-monoinfected individuals [6.02 (5.45-6.61) log(10)IU/mL versus 6.01 (5.36-6.59) log(10)IU/mL, respectively (p=1.0)]. In conclusion, HIV coinfection tends to be associated with higher plasma HCV RNA load, however, the magnitude of the differences is small and this effect can be counterbalanced with antiviral therapy.
