Barriers to Hepatitis C Virus (HCV) treatment initiation in patients with human immunodeficiency virus/HCV coinfection: Lessons From the interferon era

Research output: Contribution to journalArticle

Abstract

Background. Hepatitis C is a major cause of mortality among human immunodeficiency virus (HIV)-infected patients, yet hepatitis C virus (HCV) treatment uptake has historically been low. Although the removal of interferon removes a major barrier to HCV treatment uptake, oral therapies alone may not fully eliminate barriers in this population. Methods. Within the Johns Hopkins Hospital HIV cohort, a nested case-control study was conducted to identify cases, defined as patients initiating HCV treatment between January 1996 and 2013, and controls, which were selected using incidence density sampling (3:1 ratio). Controls were matched to cases on date of enrollment. Conditional logistic regression was used to evaluate factors associated with HCV treatment initiation. Results. Among 208 treated cases and 624 untreated controls, the presence of advanced fibrosis (odds ratio [OR], 2.23; 95% confidence interval [CI], 1.26-3.95), recent active drug use (OR, 0.36; 95% CI, 0.19-0.69), and non-black race (OR, 2.01; 95% CI, 1.26-3.20) were independently associated with initiation of HCV therapy. An increasing proportion of missed visits was also independently associated with lower odds of HCV treatment (25%-49% missed visits [OR, 0.49; 95% CI, 0.27-0.91] and ≥50% missed visits [OR, 0.24; 95% CI, 0.12-0.48]). Conclusions. Interferon-free treatments may not be sufficient to fully overcome barriers to HCV care in HIV-infected patients. Interventions to increase engagement in care for HIV and substance use are needed to expand HCV treatment uptake.
