Lymphotoxin β receptor signaling promotes development of autoimmune pancreatitis.

Background & Aims: Little is known about the pathogenic mechanisms of autoimmune pancreatitis (AIP), an increasingly recognized, immune-mediated form of chronic pancreatitis. Current treatment options are limited and disease relapse is frequent. We investigated factors that contribute to the development of AIP and new therapeutic strategies.

Functional flexibility of intestinal IgA - broadening the fine line.

Intestinal bacteria outnumber our own human cells in conditions of both health and disease. It has long been recognized that secretory antibody, particularly IgA, is produced in response to these microbes and hypothesized that this must play an important role in defining the relationship between a host and its intestinal microbes. However, the exact role of IgA and the mechanisms by which IgA can act are only beginning to be understood.

[Non-alcoholic steatohepatitis - from NAFLD to MAFLD].

Non-alcoholic steatohepatitis (NASH) as one entity of non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and accompanies the rise in the prevalence of obesity, diabetes mellitus, hypertension and hyperlipidemia in the western world. It is not known why some patients progress in the disease and develop inflammation in the liver, whereas others remain in the stage of simple steatosis, which generally has a benign course. However, NASH can progress to fibrosis and cirrhosis as well as hepatocellular carcinoma.

Significance of serum adiponectin levels in patients with chronic liver disease.

Adiponectin, which plays a pivotal role in metabolic liver diseases, is reduced in concentration in patients with NASH (non-alcoholic steatohepatitis). The aim of the present study was to determine adiponectin concentrations in patients with different forms and stages of chronic liver diseases. Serum adiponectin concentrations were measured in 232 fasting patients with chronic liver disease: 64 with NAFLD (non-alcoholic fatty liver disease), 123 with other chronic liver disease (e.

Effects of ursodeoxycholic acid in combination with vitamin E on adipokines and apoptosis in patients with nonalcoholic steatohepatitis.

Background/aims: Adipokines and hepatocellular apoptosis participate in the pathogenesis of nonalcoholic steatohepatitis (NASH). In a randomized trial ursodeoxycholic acid (UDCA) with vitamin E (VitE) improved serum aminotransferases and hepatic histology. The present work evaluates the effect of this combination on adipokines and hepatocellular apoptosis.

Treatment of hypercholesterolemia in patients with primary biliary cirrhosis might be more beneficial than indicated.

Cholesterol circulating levels are elevated in most of the patients with primary biliary cirrhosis. This review questions whether hypercholesterolaemia represents a cardiovascular risk in primary biliary cirrhosis and whether it should be treated. The published evidence indicates that hypercholesterolaemia in patients with primary biliary cirrhosis should be considered a cardiovascular risk factor only when other factors are present.
