Abstract

OBJECTIVES: Buprenorphine is associated with enhanced human immunodeficiency virus (HIV) treatment outcomes including increased antiretroviral therapy initiation rates, adherence, and CD4 cell counts among HIV-infected opioid-dependent individuals. Buprenorphine facilitates hepatitis C virus (HCV) treatment in opioid-dependent patients with HCV monoinfection. Less is known about buprenorphine's role in HIV/HCV coinfection. METHODS: We conducted a retrospective chart review to evaluate HCV care for HIV-infected buprenorphine patients in the first 4 years of buprenorphine's integration into a Rhode Island HIV clinic. RESULTS: Sixty-one patients initiated buprenorphine. All had HCV antibody testing; 57 (93%) were antibody-positive. All antibody-positive patients underwent HCV RNA testing; 48 (84%) were RNA-positive. Of these, 15 (31%) were not referred to HCV care. Among chronically infected patients, 3 received HCV treatment after buprenorphine; all had cirrhosis and none achieved viral eradication. At buprenorphine induction, most patients had inadequately controlled HIV infection, with detectable HIV RNA (59%) or CD4 cell count less than or equal to 350/muL (38%). CONCLUSIONS: Buprenorphine has shown limited success to date as a bridge to HCV treatment within an HIV clinic. Buprenorphine's stabilization of opioid dependence and HIV disease may permit the use of HCV therapy over time.
