Introduction: parenteral drug users (PDUs) are a population with a high prevalence of infection with the hepatitis C virus (HCV) and significant difficulties to access to treatment. Opioid replacement therapy programs regularly monitor these individuals. Objective: to effectively treat this population using a directly observed therapy (DOT) and bringing resources closer to the methadone dispensing center in Gipuzkoa (Bitarte). Methods: all methadone users that were positive for anti-HCV antibodies were included in the study. Using a simplified circuit, a hepatologist visits the center with a Fibroscan® device and requests treatment following assessment. Treatment is dispensed at the addict center, under the supervision of a psychiatrist and nursing staff. Prevalence, population characteristics and circuit effectiveness were assessed. Results: Bitarte monitors 660 individuals. Of these, 73.6 % were positive for antibodies against HCV. The prevalence of viremic infection is 62.5 %. The predominant genotype was 1a, followed by 3. A total of 38.5 % had advanced fibrosis (F3 and F4) and 38 % of users admitted to active heroin use. In all, 82.07 % (174/212) of the population received treatment and 97 % had sustained viral response (SVR) after 12 weeks. No re-infections were recorded. Conclusions: the prevalence of viremic HCV infection among PDUs under treatment with methadone is 62 %. The linkage to care strategy was effective and > 80 % of the population with an active infection have been treated so far.
