[Fibrotic diseases in the gastrointestinal tract : Liver fibrosis and more].

Chronic liver damage, such as metabolic dysfunction-associated steatotic liver disease (MASLD), viral hepatitis B or C, cholestatic hepatitis (PBC, PSC), toxic damage (alcohol) or genetic alterations (hemochromatosis, Wilson's disease, etc.) usually cause a chronic inflammatory response in liver cells or bile duct epithelial cells. In the long term this chronic inflammatory response can lead to scarring of the liver, a condition known as fibrosis.

Sub-optimal therapy of patients with primary biliary cholangitis (PBC) in the real-life stetting of the German PBC cohort.

Real-world data on the management of patients with primary biliary cholangitis (PBC) are so far scarce in Germany. Therefore, we aimed to establish a nationwide registry and describe the clinical characteristics and therapy of PBC patients.Three different cohorts defined as ursodeoxycholic acid (UDCA) responders, as inadequate responders according to Paris II criteria, and as newly diagnosed patients were prospectively recruited.

Hepatic Topology of Glycosphingolipids in -Infected Hamsters.

Schistosomiasis is a neglected tropical disease caused by worm parasites of the genus . Upon infection, parasite eggs can lodge inside of host organs like the liver. This leads to granuloma formation, which is the main cause of the pathology of schistosomiasis.

infection induces hepatic metallothionein and S100 protein expression alongside metabolic dysfunction in hamsters.

Schistosomiasis, a widespread neglected tropical disease, presents a complex and multifaceted clinical-pathological profile. Using hamsters as final hosts, we dissected molecular events following infection in the liver-the organ most severely affected in schistosomiasis patients. Employing tandem mass tag-based proteomics, we studied alterations in the liver proteins in response to various infection modes and genders.

Serum Chemerin Is Decreased by Roux-en-Y Gastric Bypass and Low Calorie-Formula Diet in Obese Individuals.

The pleiotropic chemokine chemerin is involved in multiple processes in metabolism and inflammation. The present study aimed to elucidate its regulation in morbid obesity and during therapy-induced rapid weight loss. A total of 128 severely obese patients were enrolled, and their basal anthropometric and clinical parameters were assessed.

Hepatocyte integrity depends on c-Jun-controlled proliferation in Schistosoma mansoni infected mice.

Schistosomiasis is a parasitic disease affecting more than 250 million people worldwide. The transcription factor c-Jun, which is induced in S. mansoni infection-associated liver disease, can promote hepatocyte survival but can also trigger hepatocellular carcinogenesis.

Schistosoma mansoni-Induced Oxidative Stress Triggers Hepatocellular Proliferation.

Background & Aims: Schistosomiasis is one of the most prominent parasite-induced infectious diseases, affecting more than 250 million people. Schistosoma mansoni causes metabolic exhaustion and a strong redox imbalance in the liver, causing parenchymal damage, and may predispose for cancer. We investigated whether oxidative stress provokes hepatocellular proliferation upon S.

Interleukin-13 (IL-13)-A Pleiotropic Cytokine Involved in Wound Healing and Fibrosis.

The liver, as a central metabolic organ, is systemically linked to metabolic-inflammatory diseases. In the pathogenesis of the metabolic syndrome, inflammatory and metabolic interactions between the intestine, liver, and adipose tissue lead to the progression of hepatic steatosis to metabolic-dysfunction-associated steatohepatitis (MASH) and consecutive MASH-induced fibrosis. Clinical and animal studies revealed that IL-13 might be protective in the development of MASH through both the preservation of metabolic functions and Th2-polarized inflammation in the liver and the adipose tissue.

[Drug toxic hepatopathy - an underestimated danger].

Drug-induced toxic hepatopathies and drug-induced liver injury, DILI, are characterized by a variety of clinical manifestations and therefore represent a significant diagnostic challenge. This article shows how DILI is diagnosed and what therapy options exist. Current special cases of DILI genesis are also discussed (DOACs, IBD drugs, tyrosine kinase inhibitors).

A Novel Insertion in the Hepatitis B Virus Surface Protein Leading to Hyperglycosylation Causes Diagnostic and Immune Escape.

Chronic hepatitis B virus (HBV) infection is a global health threat. Mutations in the surface antigen of HBV (HBsAg) may alter its antigenicity, infectivity, and transmissibility. A patient positive for HBV DNA and detectable but low-level HBsAg in parallel with anti-HBs suggested the presence of immune and/or diagnostic escape variants.
