[Short-term treatment of Hepatitis C in heroin-dependent patients].

BACKGROUND

Standardized treatment (24-week) with pegylated interferon and ribavirin induces sustained virological response in 80 % of patients with Hepatitis C (HCV) genotype 2 or 3. Most patients who are dependent on heroin and receiving methadone maintenance therapy (MMT) have been excluded from this treatment due to concerns about compliance. Short-term therapy (14 weeks) of other patient groups have shown promising results. The purpose of this study was to investigate the feasibility, efficacy and adverse effects of short-term treatment in a group of MMT patients with chronic hepatitis C infection genotype 3.

MATERIAL AND

METHODS

Eight such patients were treated with weekly pegylated interferon injections (180 microg) and daily ribavirin tablets (800 mg) for 14 weeks. A nurse gave the injections and the patients were followed-up closely with weekly meetings, telephone and SMS.

RESULTS

Virus was eradicated in all patients after four weeks (RVR = 100 %). Seven patients completed treatment and all had undetectable virus at 14 weeks (88 %). At follow-up six months post treatment, six patients had sustained virus response (SVR = 75 %), the last patient refused to be tested. The adverse effects were of moderate intensity and could be treated with dose adjustments and supportive therapy, without additional medication. Drug abuse was a minor problem during treatment and no one relapsed to drug injections.

INTERPRETATION: Short-term (14 weeks) therapy with pegylated interferon and ribavirin can then be feasible, efficient and safe for Hepatitis C genotype 3. We stress the importance of close monitoring and support from a multidisciplinary team. MMT is a good opportunity to introduce HCV treatment.
