ABSTRACT
OBJECTIVES:
To investigate whether concomitant antiretroviral therapy (ART) is a predictor of sustained virological response (SVR) in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients treated with pegylated interferon plus ribavirin.METHODS:
Three hundred and ten HIV/HCV-coinfected patients on pegylated interferon plus ribavirin treatment, 258 of them with concurrent ART, were included in this retrospective multicentre study. The predictors of SVR were evaluated.RESULTS:
SVR was shown by 114 (37%) subjects. HCV genotype 2 or 3, plasma HCV-RNA load lower than 600 000 IU/mL, an exposure to the therapy against HCV infection > or =80% of the planned dose and baseline CD4 cell counts higher than or equal to 300/mm(3) were predictors of SVR. Likewise, patients without ART and those receiving a combination including tenofovir or stavudine plus lamivudine plus a protease inhibitor (PI) or a non-nucleoside reverse transcriptase inhibitor (NNRTI) showed a higher SVR rate than the subjects who were on other ART strategies at baseline [44%, 44% and 29%, respectively; adjusted odd ratio (95% CI) for no ART = 1.96 (1.07-4.76), P = 0.025, and for ART including tenofovir or stavudine plus lamivudine plus a PI or a NNRTI = 2.08 (1.16-3.70), P = 0.014].CONCLUSIONS:
The ART strategy on starting therapy with pegylated interferon plus ribavirin is a predictor of SVR in HIV/HCV-coinfected patients. Subjects without ART and those receiving combinations of a PI or a NNRTI with a nucleos(t)ide backbone of tenofovir or stavudine plus lamivudine respond better than those who receive other regimens.
