Benefits From Sustained Virologic Response to Pegylated Interferon Plus Ribavirin in HIV/Hepatitis C Virus–Coinfected Patients With Compensated Cirrhosis

Abstract

The objective of this study was to determine the impact of sustained virologic response (SVR) to pegylated interferon (peg-IFN) plus ribavirin (RBV) on the incidence of liver-related complications and overall mortality in human immunodeficiency virus (HIV)-infected patients with compensated hepatitis C virus (HCV)-related cirrhosis. We included in this prospective cohort study 166 coinfected patients with compensated cirrhosis, who received peg-IFN plus RBV, to assess the time from the starting date of HCV therapy to the first hepatic decompensation and death due to any cause. SVR was observed in 43 (25%) individuals. Two (4.6%) patients with SVR developed liver decompensation vs 33 (26.8%) individuals without SVR (P = .002). The incidence of liver-related complications was 0.89 cases per 100 person-years (95% confidence interval [CI], .11-3.1) in SVR patients and 6.4 cases per 100 person-years (95% CI, 4.5-8.9) in non-SVR patients. Factors independently associated with liver decompensation were non-SVR (hazard ratio [HR], 8.1; 95% CI, 1.08-61.5; P = .042) and MELD score ≥9 at baseline (HR, 2.9; 95% CI, 1.2-7.2; P = .016). Two (4.6%) patients with SVR died due to any cause compared with 22 (17.9%) individuals without SVR (P = .02). MELD score ≥9 (HR, 3.1; 95% CI, 1.3-7.7; P = .011) and non-SVR (HR, 8.0; 95% CI, 1.07-61; P = .043) were independently associated with overall mortality. The achievement of SVR following peg-IFN plus RBV markedly reduces the incidence of liver-related decompensation and the overall mortality in HIV/HCV-coinfected patients with compensated cirrhosis.
