Abstract

OBJECTIVES:

Despite the high burden of hepatitis C virus (HCV)-related morbidity and mortality among HIV-positive people who use illicit drugs (PWUD), uptake of interferon-based treatments for HCV infection has been negligible among this group. Direct-acting antiviral (DAA) therapies offer an opportunity to expand treatment access among this population. The aim of this study was to explore willingness to use DAA-based regimens among HIV/HCV-coinfected PWUD in Vancouver, Canada.

METHODS:

Data were drawn from the AIDS Care Cohort to evaluate Exposure to Survival Services (ACCESS), a prospective cohort of HIV-positive PWUD. Using logistic regression analyses, we investigated factors associated with willingness to use DAA-based regimens among HIV/HCV-coinfected participants.

RESULTS:

Of 418 HIV/HCV-coinfected PWUD surveyed between June 2014 and May 2015, 295 (71%) were willing to use DAA-based regimens. In multivariable analysis, participants enrolled in methadone maintenance therapy [adjusted odds ratio (AOR) 1.61; 95% confidence interval (CI) 1.04-2.51], those with a recent assessment by an HCV specialist (AOR 2.02; 95% CI 1.28-3.19) and those who perceived that HCV infection was affecting their health (AOR 2.49; 95% CI 1.41-4.37) were more likely to be willing to use DAA-based regimens.

CONCLUSIONS:

Overall, this study found a high prevalence of willingness to use DAA-based regimens among HIV/HCV-coinfected PWUD in Vancouver. Importantly, enrolment in methadone maintenance therapy was positively associated with willingness, suggesting that integrated models of HIV, HCV and addiction care should be explored as a way to address HCV-related morbidity and mortality among HIV/HCV-coinfected PWUD.
