Abstract

Objective:

We compared the baseline characteristics, effectiveness, and tolerance of direct-acting antiviral drug (DAA)-based regimens taken by hepatitis C virus (HCV)-monoinfected and HCV/HIV-coinfected individuals in clinical practice.

Design:

We performed a prospective observational study in two tertiary centres in Madrid, Spain, which included all HCV-monoinfected and HCV/HIV-coinfected patients undergoing HCV treatment with all-oral DAA regimens in a routine clinical setting, from April 2015 to November 2015. We evaluated sustained virological response 12 weeks after the end of therapy (SVR12), adverse events, and baseline and treatment characteristics.

Results:

The study population comprised 1634 patients: 1152 HCV-monoinfected patients (70%) and 482 HCV/HIV-coinfected patients (30%). Fifty percent had cirrhosis, and 47% were peginterferon/ribavirin-experienced. HCV/HIV-coinfected patients were younger [median age (interquartile range) 51 (48–54) years vs. 59 (50–68) years; P < 0.001), more frequently male (76 vs. 54%; P < 0.001), and infected with genotypes 1a (37 vs. 17%; P < 0.001), 3 (15 vs. 7%; P < 0.001), and 4 (23 vs. 4%; P < 0.001). One of every three patients took ribavirin. SVR12 was 94% (95% confidence interval 91.7–96%) and 97% (95% confidence interval 95.7–99.4%) in coinfected and monoinfected patients, respectively, with no significant differences between the groups after adjustment for cirrhosis, genotype, and DAA combination. DAA-based regimens were well tolerated, and only 1% of patients had severe adverse events, with no differences between the populations.

Conclusions:

HCV/HIV-infected patients treated with all-oral DAA combinations achieved high rates of SVR12 that were similar to those of HCV-monoinfected patients under real-life conditions. Safety and tolerance were excellent, even in patients with end-stage liver disease.
