In adults, EHPVO mainly occurs following thrombosis, while in children it may be related to congenital malformations and/or neonatal umbilical venous catheterization. leads the cavernous transformation of portal vein absence recanalization. Portal cholangiopathy (also referred as biliopathy) is common patients with long-standing chronic PVT. It due compression large bile ducts by collaterals (p...

BACKGROUND/AIM Portal cholangiopathy (PC) is identified in over 80% of patients with portal vein thrombosis (PVT), but the true impact of this condition is not well known. This study investigated the relationship between cholangiographic abnormalities and clinical symptoms and their evolution over time. PATIENTS/METHODS 67 consecutive patients with non-tumoral non-cirrhotic PVT following a st...

Peroxisome proliferator-activated receptor-α (PPARα) has been suggested to protect against chemically induced hepatobiliary injuries in rodents. This function could mask the potential toxicities of perfluorooctanoic acid (PFOA) that is an emerging environmental contaminant and a weak ligand of PPARα. However its function has not been clarified. In this study, PFOA was found to elicit hepatocyte...

BACKGROUND AND AIM Chronic cholangiopathies have limited therapeutic options and represent an important indication for liver transplantation. Curcumin, the yellow pigment of the spice turmeric, has pleiotropic actions and attenuates hepatic damage in animal models of chemically-induced liver injury. Whether curcumin has beneficial effects in cholangiopathies is unknown. METHODS Potential anti...

Biliary innate immunity is involved in the pathogenesis of cholangiopathies in cases of biliary disease. Cholangiocytes possess Toll-like receptors (TLRs) which recognize pathogen-associated molecular patterns (PAMPs) and play a pivotal role in the innate immune response. Tolerance to bacterial PAMPs such as lipopolysaccharides is also important to maintain homeostasis in the biliary tree, but ...
