BACKGROUND: Deceased donor liver transplant (DDLT) is an uncommon procedure in India. We present our experience of DDLT from a public sector teaching hospital. METHODS: A retrospective analysis of all DDLT was performed from April 2012 till September 2016. Demographics, intraoperative, donor factors, morbidity, and outcome were analyzed. RESULTS: During the study period, 305 liver transplants were performed, of which 36 were DDLT (adult 32, pediatric 4; 35 grafts; 1 split)...

Ischemia and reperfusion injury (IRI) is an inevitable event in conventional organ transplant procedure and is associated with significant mortality and morbidity post-transplantation. We hypothesize that IRI is avoidable if the blood supply for the organ is not stopped, thus resulting in optimal transplant outcomes. Here we described the first case of a novel procedure called ischemia-free organ transplantation (IFOT) for patients with end-stage liver disease. The liver graft with severe macrovesicular steatosis was donated from a 25-year-old man...

OBJECTIVE: Donor liver function in transplantation is defined by mitochondrial function and the ability of mitochondria to recover from the sequence of warm and/or cold ischemia. Mitochondrial resilience maybe related to assembly and- subunit composition of Complex 1. The aim of this study was to determine if Complex 1 subunit composition was different in donor livers of varying quality and whether oxygen exposure had any effect. RESULTS: Five human livers not suitable for transplant were split...

PURPOSE: To determine whether magnetic resonance proton density fat fraction (MR-PDFF) estimate of negligible hepatic fat percentage (<5%) can exclude significant hepatic steatosis (≥ 10%) in living liver donor candidates obviating the need for liver biopsy. To perform intra-individual comparisons between MR-PDFF techniques for hepatic steatosis quantification. MATERIALS AND METHODS: In an ethics approved retrospective study, 144 liver donor candidates with MR spectroscopy (MRS) and six-echo Dixon MRI between 2013 and 2015 were included...

The region of Sicily, Italy, is witnessing a chronic organ shortage. Thus, to face this critical issue, the use of marginal donors has increased over time. An example of marginal donor expansion is the use of liver donors who are positive for the hepatitis C antibody (HCV+) for HCV+ patients requiring liver transplantation (LT). In view of new advances in HCV therapy, including direct-acting agents (DAAs) to treat HCV in the post-transplant setting, our study focused on a monocentric experience in a series of consecutive LTs performed in adult patients receiving HCV+ liver donor allografts...

Transplant surgeons are currently faced with the challenge to accept marginal liver transplants due to steatosis or old age. Improving organ quality by implementing a selective organ protective donor management could be the first step towards a graft of enhanced quality. However, the molecular mechanisms of such treatments are still poorly understood. Glucocorticoid medication in donor medicine has been carried out and discussed for a long time. In a recent study published in Clinical Science, Jiménez-Castro et al...

BACKGROUND & AIMS: Pretreatment of marginal organs by perfusion is a promising opportunity to make more organs available for transplantation. Protection of human donation after cardiac death (DCD) livers by a novel machine perfusion technique, hypothermic oxygenated perfusion (HOPE), was recently established. Herein, we tested whether HOPE is also useful for fatty liver grafts, using a rodent transplant model. METHODS: Rats were fed over three weeks with a special methionine-choline-deficient diet (MCDD) to induce severe hepatic macrosteatosis (≥60%)...

The on-going success of whole organ pancreatic transplantation is dependent on overcoming the imbalance between demand and supply of optimal organs as well as tackling the vast comorbidity associated with the procedure. Pancreas steatosis is a common contributing factor to the problem and with obesity pandemics affecting the global population; the size and type of organs received from donors will only make steatosis more of an issue. The aim of this review is to highlight what is known about steatosis in the context of pancreas transplantation identifying potential methods to help its evaluation...

AIMS/HYPOTHESIS: Obesity-linked ectopic fat accumulation is associated with the development of type 2 diabetes. Whether pancreatic and liver steatosis impairs insulin secretion is controversial. We examined the crosstalk of human pancreatic fat cells with islets and the role of diabetogenic factors, i.e. palmitate and fetuin-A, a hepatokine released from fatty liver. METHODS: Human pancreatic resections were immunohistochemically stained for insulin, glucagon, somatostatin and the macrophage/monocyte marker CD68...

AIM: PNPLA3 I148M polymorphism (rs738409 C>G) is the most important and the best known polymorphism for nonalcoholic fatty liver disease (NAFLD). However, little is known about the effect of this polymorphism on NAFLD after liver transplantation (LT). We aimed to evaluate the association between this polymorphism and post-LT NAFLD. METHODS: We designed a prospective case-control study. Among adult recipients who underwent LT between April 2014 and October 2015, those whose whole blood were preoperatively collected for genotyping in both recipients and coupled donors and those who have undergone protocol biopsy at post-LT 1 year were enrolled...

OBJECTIVE: Marginal livers (ML) have been used to expand the donor pool. National utilization of MLs is variable, and in some centers, they are never used. We examined the outcomes of MLs in the largest single center series of MLs used to date and compared outcomes to standard (SL) and living donor (LD) livers. METHODS: Analysis of a prospectively maintained database of all liver transplants performed at our institution from 1998 to 2016. ML grafts were defined as livers from donors >70, livers discarded regionally and shared nationally, livers with cold ischemic time >12 hours, livers from hepatitis C virus positive donors, livers from donation after cardiac death donors, livers with >30% steatosis, and livers split between 2 recipients...

The process of ageing has an impact on the entire human body including the organ systems. In transplantation, professionals are daily faced with risk assessment of suitable donor offers , whether to accept a liver graft for a specific recipient. In this context, livers from elderly donors are more frequently accepted for transplantation, to increase the donor pool and compensate the high waiting list mortality. In the current practice it is not unusual to accept 60-year old donor livers for transplantation, as the donor demographics have significantly changed over the years...

Liver steatosis frequently occurs following liver transplantation (LT) and can affect patient outcome. Here, we aimed to clarify the steatosis and steatohepatitis risk factors that apply after living-donor LT for chronic hepatitis C.We retrospectively examined 43 transplant recipients and donors, and tested for single-nucleotide polymorphisms in the patatin-like phospholipase domain-containing 3 gene (PNPLA3). Liver biopsies taken 1 year after transplantation and yearly thereafter, or when abnormal liver enzyme levels were detected, were examined by histopathology...

PURPOSE: The aim of the study is the identification of independent risk factors for re-transplantation after primary liver transplantation beyond the occurrence of hepatic artery thrombosis. METHODS: Eight hundred thirty-four adult patients undergoing primary liver transplantation were analyzed. A propensity score was developed using multivariable binary logistic regression with hepatic artery thrombosis as the dependent variable. The logit link function of the propensity score was included into multivariable Cox regression analysis for graft survival to adjust the study population...

Lipid dysregulation is a common hepatic adverse outcome after exposure to toxic drugs and chemicals. A donor-free rat hepatocyte-like (B-13/H) cell was therefore examined as an in vitro model for investigating mechanisms. The B-13/H cell irreversibly accumulated triglycerides (steatosis) in a time- and dose-dependent manner when exposed to fatty acids, an effect that was potentiated by the combined addition of hyperglycaemic levels of glucose and insulin. B-13/H cells also expressed the LXR nuclear receptors and exposure to their activators - T0901317 or GW3965 - induced luciferase expression from a transfected LXR-regulated reporter gene construct and steatosis in a dose-dependent manner with T0901317...

BACKGROUND: The obesity epidemic has significantly increased the incidence and severity of hepatic steatosis in liver surgery patients and liver donors, potentially impacting postoperative liver regeneration and function. Development of a non-invasive means to quantify hepatic steatosis would facilitate selection of candidates for liver resection and transplant donation.

BACKGROUND: The accuracy of computed tomography (CT) for detecting donor hepatic steatosis (HS) before liver transplantation is not well established. METHODS: A meta-analysis was performed to determine the accuracy of CT for HS detection in liver donor candidates. Pooled sensitivity, specificity, positive and negative likelihood ratios, hierarchical summary receiver operating characteristic (HSROC) curves, and the area under the curve (AUC) were estimated using HSROC and bivariate random-effects models...

In pediatric liver transplantations with LFS grafts, higher incidences of graft dysfunction probably occur due to IRI. It was postulated that increasing the blood supply to the graft by means of a meso-caval shunt could ameliorate the IRI. Eleven pigs underwent liver transplantation and were divided into two groups: LFS and LFS+SHUNT group. A series of flowmetric, metabolic, histologic, and molecular studies were performed. No significant metabolic differences were observed between the groups. One hour after reperfusion, portal flow was significantly lower in the recipients than in the donors, proving that the graft was maintained in low portal blood flow, although the shunt could promote a transient increase in the portal blood flow and a decrease in the arterial flow...

Although early allograft dysfunction (EAD) negatively impacts survival from the first months following liver transplantation (LT), direct-acting antiviral agents (DAAs) have revolutionized hepatitis C virus (HCV) therapy. We investigated the EAD definition best predicting 90-day graft loss and identified EAD risk factors in HCV-positive recipients. From November 2002 to June 2016, 603 HCV-positive patients (hepatocellular carcinoma, 53.4%) underwent a first LT with HCV-negative donors. The median recipient Model for End-Stage Liver Disease (MELD) score was 15, and the median donor age was 63 years...

Erucic acid (EA) is one of the key fatty acids usually found in canola oil, mustard oil and rapeseed oil. Consumption of EA in primates was found to cause myocardial lipidosis and cardiac steatosis. To have an insight of the effect of EA in humans, we performed in vitro interaction studies of EA with the primary plasma protein, human serum albumin (HSA). Spectroscopic (UV-vis and fluorescence) analysis of the HSA-EA interaction revealed a static mode of quenching with binding constant Kb ∼10(4) reflecting high affinity of EA for HSA...
