Abstract
ABSTRACT A shortage of donor hearts remains a critical problem in cardiac transplantation, resulting in longer recipient wait times and increased wait list mortality. The disparity between available donor hearts and patients with end-stage heart failure who need transplant is expected to grow. The donor heart pool can be increased by using organs from expanded criteria, Public Health Service increased risk, hepatitis C, and donation after circulatory death donors.

Center-level trends in utilization of HCV-exposed donors for HCV-uninfected kidney and liver transplant recipients in the United States. Am J Transplant 2019; 19:2329-2341. [PMID: 30861279 PMCID: PMC6658335 DOI: 10.1111/ajt.15355] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 02/15/2019] [Accepted: 03/05/2019] [Indexed: 01/25/2023]
Abstract
Several single-center reports of using HCV-viremic organs for HCV-uninfected (HCV-) recipients were recently published. We sought to characterize national utilization of HCV-exposed donors for HCV- recipients (HCV D+/R-) in kidney transplantation (KT) and liver transplantation (LT). Using SRTR data (April 1, 2015-December 2, 2018) and Gini coefficients, we studied center-level clustering of 1193 HCV D+/R- KTs and LTs. HCV-viremic (NAT+) D+/R- KTs increased from 1/month in 2015 to 22/month in 2018 (LTs: 0/month to 12/month). HCV-aviremic (Ab+/NAT-) D+/R- KTs increased from < 1/month in 2015 to 26/month in 2018 (LTs: <1/month to 8/month). HCV- recipients of viremic and aviremic kidneys spent a median (interquartile range [IQR]) of 0.7 (0.2-1.6) and 1.6 (0.4-3.5) years on the waitlist versus 1.8 (0.5-4.0) among HCV D-/R-. HCV- recipients of viremic and aviremic livers had median (IQR) MELD scores of 24 (21-30) and 25 (21-32) at transplantation versus 29 (23-36) among HCV D-/R-. 12 KT and 14 LT centers performed 81% and 76% of all viremic HCV D+/R- transplants; 11 KT and 13 LT centers performed 76% and 69% of all aviremic HCV D+/R- transplants. There have been marked increases in HCV D+/R- transplantation, although few centers are driving this practice; centers should continue to weigh the risks and benefits of HCV D+/R- transplantation.

Abstract
Historically, potential lung donors who have detectable antibodies to hepatitis C virus have been declined by most centers due to concern for possible disease transmission. We sought to evaluate hepatitis C viral transmission rates from donors who were known to be HCV Ab positive but HCV NAT negative. We performed a single-center retrospective review of a prospectively collected database for lung transplant recipients at our center including HCV Ab+NAT- donors (approved January 2017). Donor and recipient demographic data were compiled, and records were queried to ascertain rate of seroconversion. During the study period (1/1/17 to 8/9/17), a total of 64 recipients underwent lung transplantation. Thirteen (20%) donors were HCV Ab+NAT-. All recipients of HCV Ab+NAT- grafts were HCV Ab- at the time of transplant. Recipients of grafts from HCV Ab+NAT- donors underwent protocol NAT at 2 and 12 months and all are NAT- to date. One recipient developed reactive HCV Ab at 6 months post-transplant. Follow-up NAT showed HCV RNA to be undetectable. To date, use of HCV Ab+NAT- donors in lung transplantation has yielded favorable outcomes, with evidence of one transient seroconversion suggesting this practice may increase access to life-saving transplantation to those in need.

Population level outcomes and cost-effectiveness of hepatitis C treatment pre- vs postkidney transplantation. Am J Transplant 2018; 18:2483-2495.

Abstract
Direct-acting antivirals approved for use in patients with end-stage renal disease (ESRD) now exist. HCV-positive (HCV+) ESRD patients have the opportunity to decrease the waiting times for transplantation by accepting HCV-infected kidneys. The optimal timing for HCV treatment (pre- vs posttransplant) among kidney transplant candidates is unknown. Monte Carlo microsimulation of 100 000 candidates was used to examine the cost-effectiveness of HCV treatment pretransplant vs posttransplant by liver fibrosis stage and waiting time over a lifetime time horizon using 2 regimens approved for ESRD patients. Treatment pretransplant yielded higher quality-adjusted life years (QALYs) compared with posttransplant treatment in all subgroups except those with Meta-analysis of Histological Data in Viral Hepatitis stage F0 (pretransplant: 5.7 QALYs vs posttransplant: 5.8 QALYs). However, treatment posttransplant was cost-saving due to decreased dialysis duration with the use of HCV-infected kidneys (pretransplant: $735 700 vs posttransplant: $682 400). Using a willingness-to-pay threshold of $100 000, treatment pretransplant was not cost-effective except for those with Meta-analysis of Histological Data in Viral Hepatitis stage F3 whose fibrosis progression was halted. If HCV+ candidates had access to HCV-infected donors and were transplanted ≥9 months sooner than HCV-negative candidates, treatment pretransplant was no longer cost-effective (incremental cost-effectiveness ratio [ICER]: $107 100). In conclusion, optimal timing of treatment depends on fibrosis stage and access to HCV+ kidneys but generally favors posttransplant HCV eradication.

Abstract
PURPOSE OF REVIEW To highlight the changing landscape of hepatitis C virus (HCV) infection in the context of organ transplantation. This focuses on areas of controversy and future potential in the era of highly effective direct-acting antiviral (DAA) agents. RECENT FINDINGS Since the advent of safe and highly effective DAA therapy, HCV infection is now curable in virtually all cases, including organ transplant recipients. Excellent drug tolerability and safety combined with high cure rates across all organ groups means that HCV is no longer a barrier to transplantation or its outcomes. Mounting data demonstrate the safety of using organs from HCV-infected donors with subsequent treatment of HCV in the recipient and a potential to expand the donor pool. Historical data demonstrating inferior survival in transplant recipients with HCV is of limited relevance in the DAA era. Virtually all transplant recipients with HCV infection can be cured, while early data also suggest excellent outcomes in recipients of organs from HCV viremic donors. The optimal timing of HCV therapy in relation to transplantation and the optimal use of organs from HCV viremic donors remain areas of controversy and ongoing research efforts.
