The experience of re-infection among people who inject drugs successfully treated for hepatitis C.

Introduction: Highly effective direct-acting antiviral (DAA) agents have changed the landscape of hepatitis C virus infection (HCV) treatment and have become more available to people who inject drugs (PWID) over the past several years. Although many achieve a sustained virologic response (SVR), a small proportion will become re-infected. This study examined experiences of re-infection among participants in Project HERO, a large multi-site treatment trial designed to test alternative treatment delivery models for DAAs.

Methods: Study staff conducted qualitative interviews with twenty-three HERO participants who experienced reinfection following successful treatment for HCV. Interviews focused on life circumstances and experiences with treatment/re-infection. We conducted a thematic analysis, followed by a narrative analysis.

Results: Participants described challenging life circumstances. The initial experience of cure was joyful, leading participants to feel that they had escaped a defiled, stigmatized identity. Re-infection was very painful. Feelings of shame were common. Participants with fully developed narratives of re-infection described both a strong emotional response as well as a plan for avoiding re-infection during retreatment. Participants who lack such stories showed signs of hopelessness and apathy.

Conclusion: Though the promise of personal transformation through SVR may be motivating for patients, clinicians should be cautious about how they describe the "cure" when educating patients about HCV treatment. Patients should be encouraged to avoid stigmatizing, dichotomizing language of the self, including terms such as "dirty" and "clean." In acknowledging the benefits of HCV cure, clinicians should emphasize that re-infection does not mean failed treatment; and that current treatment guidelines support retreatment of re-infected PWID.
