Donor livers marginally acceptable or acceptable according to extended criteria are more frequently transplanted due to the growing discrepancy between demand and availability of donor organs. One type of marginally acceptable graft is a steatotic donor liver, because it is more sensitive to ischemia-reperfusion injury. Thus, quantitative assessment of steatosis is crucial prior to liver transplantation. Extent of steatosis of 49 pre-reperfusion liver biopsies from patients who received orthotopic liver transplantation was assessed by three techniques: semi-quantitative histological evaluation, computerized histomorphometry, and NMR-based estimation of fat content...

BACKGROUND: A measure of donor liver quality, the donor liver index, was developed and validated for the UK population of transplant recipients. Unlike previously proposed measures, this index is only based on variables that are available at the point of retrieval, and so does not include cold ischaemic time. METHODS: Indices of liver quality were based on data from the UK Transplant Registry on all 7929 liver transplants between January 2000 and December 2014. RESULTS: The donor liver index (DLI) was based on factors shown to affect graft survival, which included donor age, sex, height, type (donor after brain death or circulatory death), bilirubin, smoking history, and whether the liver was split...

Non-alcoholic steatohepatitis (NASH) is characterized by liver steatosis and inflammation. Currently, the underlying mechanisms leading to hepatic inflammation are not fully understood and consequently, therapeutic options are poor. Non-alcoholic steatohepatitis (NASH) and atherosclerosis share the same etiology whereby macrophages play a key role in disease progression. Macrophage function can be modulated via activation of receptor-ligand binding of Notch signaling. Relevantly, global inhibition of Notch ligand Delta-Like Ligand-4 (DLL4) attenuates atherosclerosis by altering the macrophage-mediated inflammatory response...

BACKGROUND AND AIMS: Alcoholic liver disease (ALD) is a leading cause of liver failure and mortality. In humans, severe alcoholic hepatitis is associated with key changes of intestinal microbiota (IM), which influences individual sensitivity to develop advanced ALD. We used the different susceptibility to ALD observed in two distinct animal facilities to test the efficiency of two complementary strategies (fecal microbiota transplantation and prebiotic treatment) to reverse dysbiosis and prevent ALD...

Nonalcoholic fatty liver disease (NAFLD) is a disease of attention because of increase in prevalence from 20% to 41%. The clinical and pathological conditions in patients with NAFLD range from steatosis alone to nonalcoholic steatohepatitis (NASH) with or without fibrosis to hepatic cancer. In the United States, NAFLD was the second-leading indication for liver transplant between 2004 and 2013. Although imaging studies such as magnetic resonance elastography and the use of diagnostic panels and scoring systems can provide a fairly accurate diagnosis of NAFLD, there are few treatment options for patients with mild to moderate disease other than lifestyle modification...

: MRI has emerged as the most comprehensive noninvasive diagnostic tool for focal liver lesions and diffuse hepatobiliary disorders. The introduction of hepatobiliary contrast agents, most notably gadoxetic acid (GA), has expanded the role of MRI, particularly in the functional imaging of chronic liver diseases, such as nonalcoholic fatty liver disease (NAFLD). GA-enhanced MRI (GA-MRI) may help to distinguish between the two subgroups of NAFLD, simple steatosis and nonalcoholic steatohepatitis...

Current drastic shortage of donor organs has led to acceptance of extended-criteria donors for transplantation, despite higher risk of primary non-function. Here, we report the impact of subnormothermic machine perfusion (SMP) preservation on the protection of >50% macro-steatotic livers. Dietary hepatic steatosis was induced in Wistar rats via 2-day fasting and subsequent 3-day re-feeding with a fat-free, carbohydrate-rich diet. This protocol induces 50-60% macrovesicular steatosis, which should be discarded when preserved via cold storage (CS)...

BACKGROUND: Older liver grafts have been considered in the past decade due to organ shortage. The aim was to compare outcomes after liver transplantation with either younger or older donors. METHODS: Patients transplanted in our center between 2004 and 2014 with younger donors (younger than 60 years; n = 253) were compared with older donors (older than 75 years; n = 157). Multiorgan transplantations, split grafts, or non-heart-beating donors were not included. RESULTS: Donors in the older group were mostly women deceased from stroke, and only 3 patients had experienced cardiac arrest...

NAFLD is a common condition linked to obesity, type 2 diabetes, and metabolic syndrome. Simple hepatic steatosis is a risk factor for inflammatory reactions in the liver (NASH), which may lead to cirrhosis. While the mechanism is unclear, NAFLD and NASH are associated with panhypopituitarism, which in the pediatric population often results from craniopharyngioma or pituitary adenoma and the sequelae of treatment, causing hypothyroidism, adrenal insufficiency, hypogonadotropic hypogonadism, and GH deficiency...

Background: The outcome of the patients after liver transplant is complex and to characterize the risk for complications is not always easy. In this context, the hepatic post-reperfusion biopsy is capable of portraying alterations of prognostic importance. Aim: To compare the results of liver transplantation, correlating the different histologic features of the hepatic post-reperfusion biopsy with graft dysfunction, primary non-function and patient survival in the first year after transplantation...

UNLABELLED: There are 40 000-60 000 patients with cirrhosis in the Czech Republic. 2 000 die of this disease yearly. This group of patients needs a complex treatment and it is mostly an internist cooperating with other specialists. The most important for an ambulant internist is to diagnose the disease as soon as possible and start with treatment of chronic liver disease that could lead to a cirrhosis. It means especially chronic viral hepatitis, alcoholic or non-alcoholic steatosis/steatohepatitis, auto-immune liver damage and metabolic disease...

BACKGROUND & AIMS: Liver transplantation is the only solution for terminal liver disease. This study aims to determine the association between severity of liver graft steatosis, as well as other risk factors, and poor prognosis of liver transplantation. METHODS: The degree of steatosis was analysed in 563 consecutive liver transplantation and classified by histological examination as M0 (0%), M1 (<30%), M2-1 (30%-39%), M2-2 (40%-49%), M2-3 (50%-59%) or M3 (≥60%)...

Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of liver diseases from simple steatosis with hepatic lipid accumulation to end-stage liver disease with decompensated cirrhosis, liver failure and hepatocellular carcinoma. Recent data from the USA showed that in 2013, NAFLD was the second most frequent indication for liver transplantation behind hepatitis C. Since there are now effective treatments for hepatitis C and there is currently no licensed treatment for NAFLD, it has been predicted that over the next 10-15 years, NAFLD will replace hepatitis C as the most frequent indication for liver transplantation...

The increased prevalence of obesity worldwide threatens the pool of living liver donors. While the negative effects of graft steatosis on liver donation and transplantation is well known, the impact of obesity in the absence of hepatic steatosis on outcome of living donor liver transplantation (LDLT) is unknown. Therefore, we compared the outcome of LDLT using donors with a BMI<30kg/m(2) vs donors with a BMI ≥30kg/m(2) . Between April 2000-May 2014, 105 patients received a right lobe liver graft from donors with BMI ≥30kg/m(2) , while 364 recipients were transplanted with grafts from donors with BMI<30kg/m(2) ...
