A genome-wide association screen for primary biliary cirrhosis risk alleles was performed in an Italian cohort. The results from the Italian cohort replicated IL12A and IL12RB associations, and a combined meta-analysis using a Canadian dataset identified newly associated loci at SPIB (P = 7.9 x 10(-11), odds ratio (OR) = 1.46), IRF5-TNPO3 (P = 2.8 x 10(-10), OR = 1.63) and 17q12-21 (P = 1.7 x 10(-10), OR = 1.38).

Background: Increasing evidence suggests an association between gut microbiota and Autoimmune Liver Diseases (AILDs). However, causal inference remains controversial due to confounding bias in observational studies. Additionally, there is currently no clear evidence indicating that immune cells act as intermediate phenotypes in the pathogenesis of AILDs.

Background: Anti-mitochondrial M2 antibody (AMA-M2) is a specific marker for primary biliary cholangitis (PBC) and it could be also presented in non-PBC individuals.
Methods: A total of 72173 Chinese health check-up individuals tested AMA-M2, of which non-PBC AMA-M2 positive individuals were performed follow-up. Baseline data of both clinical characteristics and laboratory examinations were collected in all AMA-M2-positive individuals.

This primigravid pregnant woman had a new diagnosis of primary biliary cholangitis (PBC) that was treated with a combination of ursodeoxycholic acid (UDCA) and bezafibrate. Pregnancy may unmask underlying chronic hepatic disorders in susceptible women and, in some cases, the associated abnormalities of liver function or increased serum bile acids (hypercholanaemia) can result in significant fetal and maternal risk. Maternal pruritus, with associated sleep deprivation, may cause considerable distress.

Malignant obstructive jaundice (MOJ) encompasses a range of diseases stemming from malignant tumors such as cholangiocarcinoma, pancreatic cancer, and primary liver cancer, among others, which cause obstruction in both intra- and extra-hepatic bile ducts. This obstruction may lead to elevated bilirubin levels, hepatic function impairment, and a low rate of successful surgical resection in clinical settings. There are various minimally invasive treatment options for MOJ, including endoscopic biliary drainage, ultrasound-guided procedures, and percutaneous biliary tract puncture drainage.
