Background

Recently a consensus was reached on the treatment of the HCV-infected, injection drug user (IDU) with pegylated interferon and ribavirin [1]. It is yet unclear as to whether these best-practice guidelines have been followed to good result due to multiple perceived barriers to treatment initiation.

Materials and methods

A systematic literature search in PubMed / MEDLINE, was performed. Peer-reviewed journal articles investigating barriers to treatment and therapeutic outcomes were retrieved and critically appraised. Twenty studies identifying issues related to treatment initiation and twenty-six studies presenting therapeutic outcomes were analyzed. Results are summarized and presented in evidence tables. Pooling and further statistical analysis was not justified because of heterogeneity of the identified studies.

Results

Despite being handicapped by negative views on treatment eligibility, clinical studies indicate that IDUs can be successfully treated for HCV, even in the setting of ongoing drug use. Rates of sustained virological response (SVR) were similar to control groups while patient compliance, treatment adverse effects and potential re-infection didn't have a significant impact on the therapeutic outcome. Therapy can be initiated during the early phase of drug treatment, regardless of the drug treatment strategy.

Conclusions

The evolving body of medical evidence indicates that IDUs can be effectively treated for HCV despite the persistence of putative, psychosocial barriers to treatment. Our approach to an addicted patient who needs HCV treatment, should not be clouded by perception or prejudice, but instead focus on patient education, interdisciplinary collaboration and close monitoring of the appropriate biological treatment.
