The objective of this prospective, observational clinical study was to evaluate the safety and efficacy of once-daily and twice-daily directly observed therapy (DOT) in human immunodeficiency virus (HIV)-infected patients undergoing methadone treatment. Methadone and highly active antiretroviral therapy (HAART) were dispensed daily as DOT, with patients in the twice-daily HAART group self-administering the second dose. Clinical and laboratory end points were monitored, along with the impact of ongoing cocaine use. We studied 54 patients coinfected with HIV and hepatitis C virus. At baseline, the median virus load was 111,000 copies/mL, and the median CD4+ cell count was 165 cells/mm3. After a median of 24 months, 17 of 29 patients in the once-daily HAART group and 18 of 25 in the twice-daily HAART group had virus loads of <400 copies/mL, regardless of ongoing cocaine use. Thirty-two patients required methadone dose adjustment, which was managed without modification of HAART. Treatment-limiting hepatic toxicity was rare. A DOT program of coadministered methadone and HAART can be implemented with good results, even for patients who continue to use cocaine.

We assessed feasibility and outcome of hepatitis C virus (HCV) treatment in male correctional inmates in British Columbia, Canada. We reviewed the medical charts of 114 treated inmates; 80 had complete data for treatment outcome. Approximately 4 of 5 inmates completed treatment (78.8%); 66.3% achieved sustained virological response. Those who completed treatment, those with injection drug use as a risk factor, and those with genotypes 2 and 3 were significantly more likely to achieve sustained virological response. HCV treatment in correctional inmates is feasible and effective.

There was excellent SVR and adherence to treatment with interferon and ribavirin. This experience highlights an important opportunity to treat a population with a high prevalence of HCV-positive persons who may otherwise not seek treatment.
