Data regarding the use of all-oral direct-acting antivirals in HIV/hepatitis C virus (HCV)-coinfected patients with advanced liver fibrosis are required, because they are generally under-represented in clinical trials. This study sought to evaluate the use of these drugs in a cohort of coinfected patients, mostly with factors that have previously been recognized as predictors of treatment failure.Methods:
COINFECOVA-2 is an observational, multicenter study conducted in Eastern Spain. Data of all HIV/HCV-coinfected patients treated with direct-acting antiviral under real-life conditions were retrospectively collected, and factors associated with treatment success or safety were analysed.Results:
Among 515 included patients, 96% were on antiretroviral therapy and 89.5% had an HIV-RNA less than 50 copies/ml. HCV genotype (G) distribution was 47% G-1a, 20% G-4, 14.4% G-1b, and 12.8% G-3. Patients with cirrhosis were 54.2%, and 46% failed to prior HCV-therapies. Overall, 92.8% patients (95% confidence interval: 90.2–94.9) achieved sustained virologic response (SVR12). Cirrhosis was the only factor associated with treatment failure, and SVR12 rate was significantly lower in patients with liver stiffness at least 21 kPa. Adverse events were reported in 36.7%, but only two patients (0.4%) discontinued treatment because of adverse events. The bivariate analysis showed an association between ribavirin use and an increased risk of adverse events (odds ratio 2.84; 95% confidence interval: 1.95–4.1; P ≤ 0.0001).Conclusion:
This heterogeneous cohort of coinfected patients showed a high rate of SVR12. Among cirrhotic patients, those with a liver stiffness at least 21 kPa had a higher probability of treatment failure. Ribavirin use seems to increase the appearance of adverse events.
