BACKGROUND: The direct acting antivirals (DAAs) for treatment of hepatitis C virus (HCV) infection have sustained virologic response (SVR) rates of greater than 90% in most patients. However, data evaluating DAA use in transplant patients are limited. The goal of this study was to evaluate the effectiveness and safety of HCV treatment in this high-risk population.
METHODOLOGY: This single-center retrospective study included liver, kidney, lung, and/or heart transplant patients who were treated for HCV infection with DAAs. The primary objective was to identify drug-drug interactions between DAAs and immunosuppressants by comparing immunosuppression dosages and levels at baseline and week 4 of HCV treatment. As secondary objectives, we described the percentage of patients with new or worsening rejection and/or graft dysfunction during HCV treatment, and the percentage of study patients who achieved SVR.
RESULTS: Of the 108 patients included, the majority had liver (76%) or kidney (13%) transplants. Simeprevir plus sofosbuvir was the most commonly prescribed HCV treatment (33.9%) and tacrolimus was the most common immunosuppressant (91%). We did not detect a statistically significant difference in immunosuppression dosages or levels during HCV treatment. Furthermore, only one patient (<1%) experienced rejection and five patients (4.6%) had six episodes of graft dysfunction while on DAAs. Efficacy was high with 98% of patients achieving SVR.
CONCLUSION: DAAs appear to be safe and effective for HCV treatment in patients with a history of liver and/or kidney transplantation. More data are needed to evaluate DAAs in lung and/or heart transplant patients.
