Abstract
Background: Direct-acting antivirals (DAAs) lead to high cure rates of Hepatitis C Virus (HCV) infections in HIV/HCV coinfected patients. Recent data suggest that treatment failures occur more often in HIV/HCV coinfected persons.Objective: We aimed to identify risk factors for treatment failure in coinfected patients.Methods: We analyzed data collected from the German Hepatitis C-Registry (DHC-R, Trials Registration number DRKS00009717). 437 HIV/HCV coinfected patients were included. Sustained virological response (SVR) rates and the impact of CD4+ count, HIV viral load, liver cirrhosis and splenomegaly were evaluated.Results: 83.5% (365/437) of the patients were male (average age: 46.6 ± 9.2 y). Most patients received antiretroviral therapy (ART) (88.1%; 385/437), had a HIV RNA ≤40 copies/ml (88.5%; 285/322) and were infected with HCV genotype (GT) 1 (77.6%; 339/437). Overall SVR12 rate was 92% (402/437). In patients with HIV RNA ≤40 copies/ml and >40 copies/ml SVR12 rates were 93.2% (272/292) and 85.3%, respectively (29/34; p = .11). SVR12 rates were 91.8% (45/49) and 92.7% (253/273; p = .84) in patients with a CD4+ <350/µl and ≥350/µl. We observed no difference in either of the subgroups in patients with cirrhosis or splenomegaly. In the univariate logistic regression analysis none of the analyzed HIV or HCV specific parameters, liver cirrhosis or splenomegaly were associated with treatment outcome.Conclusion: We found high SVR12 rates in HIV/HCV coinfected patients and no significant difference was observed due to the patients CD4+ cell count, HIV viral load, portal hypertension or liver cirrhosis.
