Nonalcoholic fatty liver disease is a type of hepatic steatosis that is not only associated with critical metabolic risk factors but can also result in advanced liver diseases. Ultrasound parametric imaging, which is based on statistical models, assesses fatty liver changes, using quantitative visualization of hepatic-steatosis-caused variations in the statistical properties of backscattered signals. One constraint with using statistical models in ultrasound imaging is that ultrasound data must conform to the distribution employed...

PURPOSE OF REVIEW: Living donor liver transplantation (LDLT) has developed into a well tolerated and viable option when deceased donor transplantation is not available. Transplant and advanced hepatobiliary surgeons from around the world have performed living donor hepatectomies consistently for decades with acceptable donor outcomes. However, optimizing the preoperative workup, donor selection, operative technique, and perioperative care will improve these outcomes. This manuscript reviews recent worldwide literature for the living liver donor...

This study evaluated multi-detector computed tomography (MDCT) scans performed on potential living donors for adult-to-adult liver transplantation (LDLT), with the aim of identifying significant findings that could be used to exclude potential transplantation donors. We retrospectively reviewed the medical records of 151 consecutive potential adult donors for LDLT from May 2007 to January 2015. Liver parenchyma steatosis, focal hepatic mass or intraabdominal malignancy, vascular variations, and donor liver volume were evaluated via MDCT...

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...

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...
