Insights
Hepatitis C (HCV) recurrence after liver transplant (LT) is declining. New direct-acting antiviral therapies have made curing HCV in LT recipients feasible, improving outcomes and reducing re-transplant needs.
Area of Science:
- Hepatology
- Transplant Surgery
- Infectious Diseases
Background:
- Recurrent hepatitis C (HCV) significantly impacts morbidity and mortality in liver transplant (LT) recipients.
- The advent of non-interferon-based therapies offers a potential strategy for HCV eradication in this vulnerable population.
Purpose of the Study:
- To evaluate the trend in HCV recurrence and treatment outcomes in LT recipients before and after the introduction of direct-acting antiviral (DAA) agents.
- To assess the feasibility and impact of HCV elimination on clinical outcomes and the need for re-transplantation.
Main Methods:
- Retrospective analysis of 634 LT recipients with HCV from January 2005 to June 2017 at UCLA.
- Data collection included transplant dates, follow-up, laboratory values, and antiviral therapy details relative to LT.
- Statistical analyses assessed trends in viral suppression, treatment rates, and re-transplantation rates over two distinct study periods.
Main Results:
- A significant trend towards HCV cure was observed both before and after LT between 2005-2013 and 2014-2016.
- Antiviral treatment rates within 12 months post-LT increased from 8% (2005-2013) to 74% (2014-2016).
- Re-LT rates within one year decreased significantly from 5.5% to 1.5% after the introduction of DAAs.
Conclusions:
- The proportion of viremic LT recipients has decreased over time, indicating successful HCV management.
- HCV elimination is achievable in LT recipients with modern direct-acting antiviral therapies.
- Curing HCV is expected to improve long-term clinical outcomes and reduce the need for repeat liver transplantation.
Abstract:
Recurrent hepatitis C (HCV) disease in liver transplant (LT) recipients is associated with significant morbidity and mortality. With the availability of noninterferon-based therapy, eliminating HCV may be achievable in LT recipients. We studied all consecutive recipients who underwent LT at the University of California Los Angeles between January 2005 and June 2017. We collected data on date of transplant and last follow-up, as well as laboratory values. We also recorded type and timing of antiviral therapy relative to LT. Analyses were performed to assess the proportion of LT recipients who are viremic after transplant. Six hundred thirty-four patients underwent LT with a diagnosis of HCV. There was a statistically significant trend for patients to be cured before (p < 0.001) and after liver transplantation (p < 0.001) for the study period of 2014 to 2016 relative to 2005 and 2013, respectively. Of the 634 recipients eligible for therapy, 8% and 74% were treated within 12 months of transplant for the study periods 2005 to 2013 and 2014 to 2016, respectively. There was a significant decrease between the two study periods in the proportion of patients undergoing re-LT 1 year after the original LT: 5.5% (n = 28/510) and 1.5% (n = 2/124) respectively for study periods 2005 to 2013 and 2014 to 2016 respectively (p = 0.011). The proportion of LT recipients who are viremic has decreased over time. Eliminating HCV in LT recipients is feasible after the introduction of direct-acting agents. Curing HCV should translate to improved clinical outcomes in LT recipients who were transplanted for HCV infection with longer follow-up. Preliminary results suggest the decreased need for transplant in the direct-acting agents era.
