Machine Perfusions in Liver Transplantation: The Evidence‐Based Position Paper of the Italian Society of Organ and Tissue Transplantation

2020

The use of machine perfusion (MP) in liver transplantation (LT) is spreading worldwide. However, its efficacy has not been demonstrated, and its proper clinical use has far to go to be widely implemented. The Società Italiana Trapianti d’Organo (SITO) promoted the development of an evidence-based position paper. A 3-step approach has been adopted to develop this position paper. First, SITO appointed a chair and a cochair who then assembled a working group with specific experience of MP in LT. The Guideline Development Group framed the clinical questions into a patient, intervention, control, and outcome (PICO) format, extracted and analyzed the available literature, ranked the quality of th…

Role of exercise-induced hepatokines in metabolic disorders.

2019

International audience; The health-promoting effects of physical activity to prevent and treat metabolic disorders are numerous. However, the underlying molecular mechanisms are not yet completely deciphered. In recent years, studies have referred to the liver as an endocrine organ, since it releases specific proteins called hepatokines. Some of these hepatokines are involved in whole body metabolic homeostasis and are theorized to participate in the development of metabolic disease. In this regard, the present review describes the role of Fibroblast Growth Factor 21, Fetuin-A, Angiopoietin-like protein 4, and Follistatin in metabolic disease and their production in response to acute exerci…

Plant sterols from foods in inflammation and risk of cardiovascular disease: a real threat?

2014

High dietary intakes of cholesterol together with sedentary habits have been identified as major contributors to atherosclerosis. The latter has long been considered a cholesterol storage disease; however, today atherosclerosis is considered a more complex disease in which both innate and adaptive immune-inflammatory mechanisms as well as bacteria play a major role, in addition to interactions between the arterial wall and blood components. This scenario has promoted nutritional recommendations to enrich different type of foods with plant sterols (PS) because of their cholesterol-lowering effects. In addition to cholesterol, PS can also be oxidized during food processing or storage, and the…

Management of Diabetes in Candidates for Liver Transplantation and in Transplant Recipients.

2021

Diabetes is common in patients wait-listed for liver transplantation due to end-stage liver disease or to hepatocellular cancer as well as in post-transplant phase (post-transplantation diabetes mellitus-PTDM). In both conditions the presence of diabetes severely affects disease burden and long-term clinical outcomes; careful monitoring and appropriate treatment are pivotal to reduce cardiovascular events and graft and recipients' death. We thoroughly reviewed the epidemiology of diabetes in the transplant setting and the different therapeutic options, from lifestyle intervention to antidiabetic drug use - including the most recent drug classes available - and to the inclusion of bariatric …

Liver injury in patients with severe acute respiratory syndrome coronavirus-2 infection: a systematic review and meta-analysis.

2020

OBJECTIVE: Coronavirus disease-19 (COVID-19) infection is a global health threat. To inform the liver community on the potential relevance of COVID-19, we performed a systematic review and meta-analysis of published data on liver injury in patients with COVID-19 infection. METHODS: We searched PubMed and Google Scholar through 22 March according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Pooled data were analyzed by using random-effects meta-analyses. RESULTS: A total of 14 studies combining data from 2.871 patients were identified. The prevalence of pre-existing liver disease was reported at 3.1%. The pooled prevalence of elevated aspartate aminot…

Prognostic Impact of 3-HM Concentration in Patients with Alcoholic or Viral Cirrhosis

2018

The role of endotoxemia related to intestinal bacterial translocation in worsening liver disease is the subject of many studies, but its impact on cirrhosis mortality has not been well evaluated. In this study, 3-hydroxymyristate (3-HM) (specific lipid of lipopolysaccharides) was directly quantified by an innovative patented assay with the aim of assessing the impact on cirrhosis mortality. The 3-HM concentration was measured in 593 patients with alcoholic or viral cirrhosis in stable clinical condition. A Cox hazards regression model was used to evaluate association between 3-HM and its fractions bound or nor bound to lipoprotein and the mortality. The 3-HM concentration was increased in p…

Progressive Endoplasmic Reticulum Stress Contributes to Hepatocarcinogenesis in Fatty Acyl-CoA Oxidase 1–Deficient Mice

2011

Fatty acyl-coenzyme A oxidase 1 (ACOX1) knockout (ACOX1(-/-)) mice manifest hepatic metabolic derangements that lead to the development of steatohepatitis, hepatocellular regeneration, spontaneous peroxisome proliferation, and hepatocellular carcinomas. Deficiency of ACOX1 results in unmetabolized substrates of this enzyme that function as biological ligands for peroxisome proliferator-activated receptor-α (PPARα) in liver. Here we demonstrate that sustained activation of PPARα in ACOX1(-/-) mouse liver by these ACOX1 substrates results in endoplasmic reticulum (ER) stress. Overexpression of transcriptional regulator p8 and its ER stress-related effectors such as the pseudokinase tribbles h…

Hepatotoxicity caused by mebendazole in a patient with Gilbert's syndrome

2019

What is known and objective Mebendazole (MBZ) is a broad-spectrum antihelminthic agent of the benzimidazole type. Although MBZ has been reported to cause hepatic injury, case reports of severe hepatic injury are very rare. We report a case of severe hepatitis after administration of MBZ in a patient with Gilbert's syndrome affected by pinworms infestation. Case summary Differently from other cases of hepatitis due to MBZ reported in the scientific literature, our patient received standard doses of MBZ for a short period of time. After 18 days from the start of therapy, he developed hepatomegaly, and increases in hepatic enzymes and bilirubin. Hepatic enzymes returned to normal over the foll…

Metabolism of rat liver cells during incubation in cold UW solution

1997

Simple cold storage of livers for transplantation activates glycolysis due to lack of oxygen. Energy derived from glycolysis may be critical for cell survival and liver cell death may occur once glycolysis is inhibited in the liver due to accumulation of end products or lack of substrates (glycogen). The relationship between cell death (lactate dehydrogenase, LDH release), anaerobic glycolysis (lactate production), and glycogen content of liver tissue was studied during cold incubation of liver slices in UW solution. Rat livers slices from male Sprague Dawley rats were incubated at 4 degrees C in UW solution, with continuous gentle shaking, under conditions of chemical hypoxia (KCN, 5 mM). …
