Hepatitis C virus reinfection after liver transplant: New chances and new challenges in the era of direct-acting antiviral agents.

ABSTRACT: The first interferon-free regimens have been approved for the treatment of patients with chronic hepatitis C virus (HCV). In the liver transplant (LT) setting, these regimens are expected to have an important effect, because graft loss due to HCV recurrence is a serious problem after LT. The response to the hitherto conventional treatment with pegylated interferon and ribavirin is poor. The significantly better response rates achieved with boceprevir-based and telaprevir-based triple therapy have led to better graft and patient survival rates, but severe drug interactions with immunosuppressants limit the feasibility of this therapy for LT patients. With the approval of sofosbuvir in January 2014, of simeprevir in May 2014, and of daclatasvir in August 2014, three antiviral agents are now available and promise to be applicable without relevant adverse effects or negative interactions with immunosuppressants. Thus, 2014 marks the beginning of a new era of treatment options for HCV recurrence after LT. Although safety and efficacy studies of several interferon-free regimens for patients with HCV recurrence after LT have achieved good preliminary results, reports of clinical experiences with LT patients are scarce. The lack of randomized studies, the small number of enrolled and carefully selected patients, and the heterogeneity of these studies make the results questionable. Real-life experiences are eagerly awaited so that clinicians can estimate the usefulness and the pitfalls of these new regimens. Additionally, the high costs of these agents may limit their accessibility for many patients. The aim of this review is to summarize the current experience with and the expectations of the new direct-acting antiviral agents for LT patients.

Project description:ImportanceFor patients awaiting heart transplant, hepatitis C-positive donors offer an opportunity to expand the donor pool, shorten wait times, and decrease wait-list mortality. While early reported outcomes among few heart transplant recipients have been promising, knowledge of 1-year outcomes in larger cohorts of patients is critical to shared decision-making with patients about this option.ObjectiveTo better define the association of hepatitis C-positive donors with heart transplant volumes, wait-list duration, the transmission and cure of donor-derived hepatitis C, and morbidity and mortality at 1 year.Design, setting, and participantsThis was a prospective, single-center observational study of 80 adult (age 18 years or older) patients who underwent heart transplant using hearts from hepatitis C-positive donors between September 2016 and April 2019 at a large academic medical center. Among donors, who were considered hepatitis C-positive if results from hepatitis C antibody and/or nucleic acid testing were positive, 70 had viremia and 10 were seropositive but did not have viremia. Follow-up was available through May 15, 2019. Comparisons were drawn with patients who underwent transplant with hearts from hepatitis C-negative donors during the same period.ExposuresIn addition to standard posttransplant management, transplant recipients who developed donor-derived hepatitis C infection were treated with direct-acting antivirals.Main outcomes and measuresThe main outcomes included wait-list duration and 1-year survival in all patients, and for those who developed donor-derived hepatitis C, the response to direct-acting antiviral treatment.ResultsOf 80 patients, 57 (71.3%) were men, 55 (68.7%) were white, and 17 (26.3%) were black; the median age at transplant was 54.5 years (interquartile range, 46-62 years). Following consent to accept hearts from hepatitis C-exposed donors, the median days to heart transplant was 4 (interquartile range, 1-18). No recipients of donors with negative nucleic acid testing results (10 [12.5%]) developed donor-derived hepatitis C. Of 70 patients who were recipients of donors with positive nucleic acid testing results, 67 (95.7%) developed donor-derived hepatitis C over a median follow-up of 301 days (interquartile range, 142-617). Treatment with direct-acting antivirals was well tolerated and yielded sustained virologic responses in all treated patients. Within the cohort with infection, 1-year patient survival was 90.4%, which was not significantly different compared with the cohort without infection or with patients who received transplants from hepatitis C-negative donors during the same period.Conclusions and relevanceIn the era of direct-acting antivirals, hepatitis C-positive donors are a viable option to expand the donor pool, potentially reducing wait-list duration and mortality. In heart transplant recipients with donor-derived hepatitis C, infection is well-tolerated and curable, and 1-year survival is equivalent to that in recipients of hepatitis C-negative donors.
