Hepatitis c and organ donor

BACKGROUND/AIMS: Direct-acting antiviral (DAA) therapy has revolutionized solid organ transplantation by providing an opportunity to utilize organs from HCV-viremic donors. Though transplantation of HCV-viremic donor organs into aviremic recipients is safe in the short term, midterm data on survival and post-transplant complications is lacking. We provide a midterm assessment of complications of lung transplantation (LT) up to 2 years post-transplant, including patient and graft survival between HCV-viremic transplantation (D+) and HCV-aviremic transplantation (D-)...

BACKGROUND & AIMS: Effective treatments for acute-on-chronic liver failure (ACLF) are a major unmet need. This proof-of-concept pilot study was aimed at evaluating the effects of plasma exchange (PE) with albumin 5% (PE-A5%) on albumin functional capacity and organ dysfunction in patients with ACLF. METHODS: Ten adult patients were enrolled in a single-center phase II, prospective, open-label, non-controlled study. Six PE-A5% sessions were performed in 10 days followed by a 1-month follow-up visit...

Hepatic ischemia-reperfusion injury(HIRI) remains to be an unsolved risk factor that contributes to organ failure after liver surgery. Our clinical retrospective study showed that lower donor liver CX3-C chemokine receptor-1(CX3CR1) mRNA expression level were correlated with upregulated pro-resolved macrophages receptor MERTK, as well as promoted restoration efficiency of allograft injury in liver transplant. To further characterize roles of CX3CR1 in regulating resolution of HIRI, we employed murine liver partial warm ischemia-reperfusion model by Wt &Cx3cr1-/- mice and the reperfusion time was prolonged from 6 h to 4-7 days...

BACKGROUND: Immune dysregulation and metabolic derangement have been recognized as key factors that contribute to the progression of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF). However, the mechanisms underlying immune and metabolic derangement in patients with advanced HBV-ACLF are unclear. AIM: To identify the bioenergetic alterations in the liver of patients with HBV-ACLF causing hepatic immune dysregulation and metabolic disorders...

We transplanted six solid organs from three hepatitis C virus (HCV) polymerase chain reaction (PCR)-positive donors during 2018-2023. Recipients were treated with glecaprevir/pibrentasvir or sofosbuvir/velpatasvir for 4-12 weeks, with all six achieving sustained virological response without significant adverse events. As occurs in other jurisdictions, solid organ transplants from HCR PCR-positive donors can be safely utilised in Australia.

BACKGROUND: Organ transplantation from donors with hepatitis C viremia (HCV) to recipients without HCV (HCV D+/R-) has excellent medical outcomes. Less is known about the psychosocial impact and experiences of HCV D+/R- recipients, particularly outside of clinical trials. METHODS: We conducted in-depth, semistructured interviews with 24 HCV D+/R- recipients (kidney, n = 8; lung, n = 7; liver, n = 5; heart, n = 3; simultaneous heart and kidney, n = 1) who received transplants outside of clinical trials and were treated for HCV after transplant to assess their experiences and perspectives...

INTRODUCTION: The prime responsibility of blood transfusion services in India is to provide safe blood. The donated blood is tested for human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), malaria and syphilis. In India, the screening of donated blood for syphilis is performed by rapid plasma reagin (RPR) or venereal disease research laboratory (VDRL), whereas the World Health Organization (WHO) recommends screening of syphilis in blood donors by enzyme-linked immunosorbent assay (ELISA)...

INTRODUCTION: This case describes passenger lymphocyte syndrome (PLS) generating human platelet antigen 1a (HPA-1a) alloantibodies against the recipient's platelets after liver transplant. Given the rarity of PLS, especially in liver transplant with HPA-1a alloantibodies, disease course and management options are poorly described. METHODS: The patient had cirrhosis secondary to nonalcoholic steatohepatitis complicated by hepatocellular carcinoma, encephalopathy, and severe ascites...

BACKGROUND: National data demonstrate that hepatitis C virus (HCV)-infected organ donors are increasingly being used in the US, including for lung transplantation. We aimed to assess whether there were any differences in the acute or chronic rejection rates at 1 year following lung transplantation from HCV-viremic versus uninfected donors. METHODS: We retrospectively reviewed all lung transplant recipients at our institution from April 1, 2017 to October 1, 2020 and then assessed various outcomes between those who received a transplant from HCV-viremic donors versus HCV-negative donors...

BACKGROUND: Worldwide, more than 39 million individuals are living with human immunodeficiency virus (HIV), 296 million with chronic hepatitis B (HBV), and 58 million with chronic hepatitis C (HCV). Despite successful treatments for these blood-borne viruses (BBVs), >1.7 million people die per annum. To combat this, the World Health Organization recommended implementing triple testing for HIV, HBV, and HCV. This systematic review aims to provide evidence for this policy, by identifying the prevalence of these BBVs and discussing the costs of available triple tests...

BACKGROUND: Children listed for heart transplantation face the highest waitlist mortality among all solid organ transplant patients (14%). Attempts at decreasing donor allograft non-utilization (41.5%) could potentially decrease waitlist mortality for pediatric heart transplant patients. Our aim was to quantify the non-utilization risk of pediatric donor heart allografts at the time of initial offering. METHODS: Using the United Network of Organ Sharing (UNOS) database, we retrospectively analyzed 8823 deceased donors (≤18 years old) data through univariable and multivariable analysis and logistic regression models...

HTLV-1 infection is spreading globally at an uncertain speed. Sexual, mother-to-child and parenteral exposure are the major transmission routes. Neither vaccines nor antivirals have been developed to confront HTLV-1, despite infecting over 10 million people globally and causing life-threatening illnesses in 10% of carriers. It is time to place this long neglected disease firmly into the 2030 elimination agenda. Current evidence supports once in life testing for HTLV-1, as recommended for HIV, hepatitis B and C, along with targeted screening of pregnant women, blood donors and people attended at clinics for sexually transmitted infections...

Heart transplantation (HTx) remains the last therapeutic resort for patients with advanced heart failure. The present work is a clinically focused review discussing current issues in heart transplantation. Several factors have been associated with the outcome of HTx, such as ABO and HLA compatibility, graft size, ischemic time, age, infections, and the cause of death, as well as imaging and laboratory tests. In 2018, UNOS changed the organ allocation policy for HTx. The aim of this change was to prioritize patients with a more severe clinical condition resulting in a reduction in mortality of people on the waiting list...

BACKGROUND: According to the current Center for Korean Network for Organ Sharing guidelines for kidney transplantation from brain-dead donors with hepatitis B or C infection, organs from hepatitis B surface antigen-positive (HbsAg+ ) or anti-hepatitis C virus-positive (HCV+ ) donors can only be transplanted into HBsAg+ or anti-HCV+ recipients. We aimed to confirm the status and the outcomes of kidney transplantation from brain-dead donors with hepatitis B or C virus in Korea. METHODS: This retrospective study included all kidney transplantations from brain-dead donors in the Korean Organ Transplantation Registry database between January 2015 and June 2020, divided into 3 groups according to donor hepatitis status...

BACKGROUND: The kidney donor profile index (KDPI) evaluates kidney donor's age, height, weight, ethnicity, cause of death, high blood pressure, diabetes, exposure to hepatitis C and estimated glomerular filtration (eGFR). Kidneys with lower KDPI scores are expected to function longer that those with higher KPDI values. The applicability of KDPI score in Chinese kidney transplant donation has not yet been validated. This study evaluated the prognostic value of KDPI score in Chinese kidney transplant patients...

BACKGROUND: Transplanting organs from hepatitis C virus (HCV)-infected donors into HCV-negative recipients has led to thousands of more transplants in the United States since 2016. Studies have demonstrated disparities in utilization of kidneys from these donors due to gender and education. It is still unknown, however, if the same disparities are seen in heart and lung transplantation. METHODS: We used Organ Procurement and Transplantation/United Network for Organ Sharing data on all isolated heart and lung transplants from November 1, 2018, to March 31, 2023, classifying donors based on their HCV nucleic acid test (NAT) result: HCV-NAT- vs HCV-NAT+...

Surveillance of the renal allograft recipient is essential when monitoring renal function to detect the early onset of rejection and alter therapeutic treatments to treat acute rejection or other causes and improve long-term graft function. If renal function begins to deteriorate, a renal biopsy is often indicated to assess the Banff grade of potential rejection or other causes, especially in the setting of polyoma BK viral load elevation. Although BK infection in the allograft is asymptomatic, reactivation of the virus is known to be associated with the acceleration of pathologic change and a poor outcome in the allograft...

BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of morbidity and mortality in the United States. For certain patients, liver transplantation (LT) may be curative. The determination of which patients would benefit most from transplant and have the lowest risk of posttransplant recurrence has evolved as technology and treatments have expanded. We aim to review epidemiological changes in the HCC landscape, selection criteria for transplant, organ allocation, bridge therapies and post-transplant recurrence, and identify points for palliative care involvement...

Normothermic machine perfusion (NMP) enables pretransplant assessment of high-risk donor livers. The VITTAL trial demonstrated that 71% of the currently discarded organs could be transplanted with 100% 90-day patient and graft survivals. Here, we report secondary end points and 5-year outcomes of this prospective, open-label, phase 2 adaptive single-arm study. The patient and graft survivals at 60 months were 82% and 72%, respectively. Four patients lost their graft due to nonanastomotic biliary strictures, one caused by hepatic artery thrombosis in a liver donated following brain death, and 3 in elderly livers donated after circulatory death (DCD), which all clinically manifested within 6 months after transplantation...

BACKGROUND: Liver transplantation is the last therapeutic option for patients with end-stage liver disease. Postreperfusion syndrome (PRS), defined as a fall in mean arterial pressure of more than 30% within the first 5 minutes after reperfusion of at least 1 minute, can occur in liver transplantation as a deep hemodynamic instability with associated hyperfibrinolysis immediately after reperfusion of the new graft. Its incidence has remained unchanged since it was first described in 1987...
