Both α-1-antitrypsin Z phenotypes and low caeruloplasmin levels are over-represented in alcohol and nonalcoholic fatty liver disease cirrhotic patients undergoing liver transplant in Ireland

Objectives Alcoholic liver disease and nonalcoholic fatty liver disease (NAFLD) are steatotic liver diseases and major causes of cirrhosis. Only a minority of patients with risk factors develop cirrhosis and genetic cofactors may be important in pathogenesis. Mutations in the Wilson’s and α-1-antitrypsin genes are not uncommon and we speculated that they may act as cofactors. Methods We investigated α-1-antitrypsin phenotyes and caeruloplasmin levels in patients undergoing elective liver transplantation. We compared patients with alcohol and NAFLD with nonsteatotic liver disease patients: viral hepatitis B or C, autoimmune hepatitis, primary biliary cholangitis and primary sclerosing cholangitis. Results Two hundred and thirty-one patients were included in the study. Pretransplant caeruloplasmin levels and α-1-antitrypsin phenotypes were available in 197 and 112 patients, respectively. α-1-Antitrypsin Z phenotypes were significantly more common in the alcohol and NAFLD group: 12/56 versus 3/56 (P

CONCLUSIONS: Considering the low number of university students disclosing sexual assaults to health professionals or support services, the results of this survey suggest more work is needed to facilitate greater disclosures to health professionals enabling victims to access the services they need regardless of alcohol use.

Abstract In this work we present an assessment of mercury (Hg) and methyl mercury (MeHg) bioaccumulation in different species of marine sponges collected off the Northwestern Mediterranean and Northeastern Atlantic coasts. Overall the results showed significant accumulation of Hg in sponges, with the Mediterranean sponge Chondrilla nucula exhibiting the highest total Hg content (up to 0.5 mg kg-1) and bio-concentration factor (BCF) up to 23. A significant inter-species variability of Hg bioaccumulation was observed among species collected at the same site. The sponges, collected in marine environment con...

Liver diseases, including liver cancer, cirrhosis, and nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH), impose a heavy disease burden worldwide [1,2]. Liver cancer and cirrhosis may derive from any chronic liver disease, such as hepatitis B/C virus (HBV/HCV) infections, alcoholic liver disease, NAFLD, haemochromatosis, and autoimmune hepatitis [3]. Over the last four decades, the prevalence of overweight has increased over fourfold in children, and there has been a great relative increase in obesity prevalence with no signs of slowing [4].

Conclusions: While there is a certain overlap between the results of the current study and published transcriptomic profiles of non-transplanted livers with steatosis, we have identified discrete characteristics of the non-alcoholic fatty liver disease in liver grafts potentially utilizable for the establishment of predictive signature. Introduction Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in industrialized countries, its prevalence being estimated at 19–31.3% (1). It encompasses a range of conditions that are thought to arise from fatty liver (simple steatosis) throu...

Liver fibrosis is a common pathway in multiple liver diseases, including viral (hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV)-HCV co-infection), autoimmune, hereditary, metabolic and toxin-mediated liver disease. These diseases can lead to hepatocellular dysfunction, distortion of liver architecture, portal hypertension and finally liver cirrhosis. Approximately 20 to 30% of patients with chronic liver disease develop cirrhosis 1. In addition, the incidence of cirrhosis is increasing due to other causes like non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steato-hepatitis ...
