Hepatitis c and organ donor

BACKGROUND: A high seroprevalence of various transfusion-transmitted infections (TTIs) in donated blood is the main safety concern, especially in low- and middle-income countries. As per the World Health Organization (WHO) recommendation, all blood donations must be tested for human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), Treponema pallidum infection, and malaria, which mainly comprises the major bulk of TTIs. AIMS: The purpose of this study is to observe the seroprevalence of hepatitis C virus and Treponema pallidum infection over the period of 5 years in blood donors of our blood center along with their epidemiological determinants with respect to age, sex, residence, occupation, and type of donors...

BACKGROUND: With rates of potential donor heart discard as high as 66% nationally, quality improvement efforts must seek to optimize donor utilization. Whether the timing of donor brain death declaration (BDD) influences organ acceptance is understudied. The authors sought to characterize the impacts of time between donor hospital admission and BDD on heart utilization and posttransplant outcomes. METHODS: All potential heart donors and recipients in the United Network for Organ Sharing database were identified (2006-2021)...

BACKGROUND AND AIMS: The importance of human leukocyte antigen (HLA) matching between liver transplant donors and recipients on graft survival remains unclear and is not a clinical consideration in liver transplantation. This study aimed to determine the relationship between HLA matching and liver graft survival using a large-scale multi-centre database (UNOS/OPTN) and multivariate logistic analysis. The secondary aim was to determine whether this relationship was influenced by transplant indication and donor status...

Despite increasing numbers of organ transplants completed each year, there continues to be an organ shortage in liver transplantation. This has led to the utilization of previously discarded or "marginal" allografts, such as those from donors with hepatitis C virus (HCV) or hepatitis B virus (HBV). The advent of direct acting antivirals and nucleos(t)ide analogs has allowed these allografts to be safely transplanted regardless of the recipients' hepatitis status with comparable graft and patient survival. Recent advances have even allowed usage of actively viremic donors with similar graft and patient outcomes...

With the demand for heart transplantation continuing to outpace the available donor organs, previously underutilized donors are now being reconsidered. We sought to describe the emerging techniques and outcomes of expanded criteria heart transplantation. A comprehensive review of the recent literature concerning expanded donor selection in heart transplantation was performed using the PubMed MEDLINE database. To characterize trends in transplant practice, the United Network for Organ Sharing (UNOS/OPTN) registry was queried for all adult isolated heart transplants since 2010, and data regarding transplant parameters was collected...

OBJECTIVES: Drug overdose (DO) deaths rose to unprecedented levels during the COVID-19 pandemic. This study examines the impact of COVID-19 on the availability of cardiac allografts from DO donors and the implications of DO donor use on recipient survival. METHODS: Heart transplants reported to the United Network for Organ Sharing (UNOS) from January 2017-November 2019 ("pre-COVID") and March 2020-June 2021 ("COVID pandemic") were analyzed with respect to DO donor status...

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.

PURPOSE: Liver transplant (LT) is the only definitive treatment for end-stage liver disease (ESLD). This review aims to explore current global LT practices, with an emphasis on challenges and disparities that limit access to LT in different regions of the world. METHODS: A detailed analysis was performed of present-day liver transplant practices throughout the world, including the etiology of liver disease, patient access to transplantation, surgical costs, and ongoing ethical concerns...

Curative hepatitis C virus (HCV) therapy has increased transplantation from HCV-infected nucleic acid test-positive donors to HCV-uninfected recipients (D+/R-). We evaluated outcomes of early and late HCV treatment among D+/R- nonliver organ transplants. Patients received HCV regimens per local standard (n = 10 sites). Outcomes were compared between early and late treatments. Early treatment regimens (ETR) (n = 56) were initiated pretransplantation to day 7 posttransplant. Late treatment regimens (LTRs) (n = 102) began median 31 (range, 8-114) days posttransplant...

BACKGROUND: The development of modern antiviral therapy for hepatitis C virus (HCV) has allowed for the transplantation of HCV nucleic acid amplification testing-positive (NAT+) donor lungs with acceptable short-term outcomes. We sought to evaluate trends and midterm outcomes of lung transplant recipients of HCV NAT+ donor allografts. METHODS: All adults undergoing isolated lung transplantation in the United Network for Organ Sharing database from January 2016 to December 2022 were included in the study...

Prevention of donor-derived disease among pediatric solid organ transplant recipients requires judicious risk-benefit assessment. Comprehensive guidelines outline specific donor risk factors and post-transplant monitoring strategies to prevent and mitigate transmission of HIV, hepatitis B, and hepatitis C. However, elimination of unanticipated donor-derived infections remains challenging. The objectives of this review are to (1) define risk of anticipated vs. unanticipated disease transmission events in pediatric solid organ transplant recipients; (2) discuss donor presentations that confer greater risk of unanticipated disease transmission; (3) develop a matrix for consideration of donor acceptance; and (4) discuss limitations and future directions for donor screening...

BACKGROUND: Despite organ shortages, the discard rate of deceased donor kidneys is high. Risk factors for this trend warrant further study. METHODS: We investigated reasons for discard in a cohort of brain death donors with marginal kidneys and procurement biopsies. Paraffin embedded procurement biopsies were systematically reevaluated and graded for the purpose of the study. Assessment included percentage of global glomerulosclerosis, Banff Lesion scores and tubular epithelial damage...

BACKGROUND: With the introduction of direct-acting antiviral therapies (DAAs), the non-use rate of hepatitis C virus (HCV)-positive donor organs (D+) has decreased significantly. We present the donor, recipient, and transplant allograft characteristics, along with recipient outcomes, in one of the largest cohorts of HCV-D+ transplants into HCV-naïve recipients (R-). METHODS: Charts of HCV D+/R- kidney (KT), liver (LT), and simultaneous liver-kidney (SLKT) transplant recipients between January 2019 and July 2022 were reviewed...

BACKGROUND: Hepatitis C virus (HCV) nucleic acid amplification test (NAAT)-positive donors have increased the organ pool. Direct-acting antivirals (DAAs) have led to high rates of treatment success and sustained virologic response (SVR) in recipients with donor-derived HCV infection without significant adverse effects, although variability remains in the timing and duration of antivirals. METHODS: This retrospective study analyzed all adult HCV-NAAT-negative transplant recipients who received an organ from HCV-NAAT-positive donors from November 24, 2018, to March 31, 2022, at Duke University Medical Center with protocolized delay of DAA initiation until after hospital discharge, with at least 180-d follow-up on all patients...

This protocol presents an optimized erythrocytes-free NEVLP system using mouse livers. Ex vivo preservation of mouse livers was achieved by employing modified cannulas and techniques adapted from conventional commercial ex vivo perfusion equipment. The system was utilized to evaluate the preservation outcomes following 12 h of perfusion. C57BL/6J mice served as liver donors, and the livers were explanted by cannulating the portal vein (PV) and bile duct (BD), and subsequently flushing the organ with warm (37 °C) heparinized saline...
