Primary biliary cholangitis (formerly primary biliary cirrhosis) is a chronic, progressive, autoimmune, cholestatic liver disease more common in middle-aged women. It is characterized by destruction of small to medium bile ducts leading to cholestasis and frequently, end-stage liver disease.
Diagnostic features are chronic biochemical cholestasis, presence of antimitochondrial antibodies and the characteristic liver biopsy findings.
Patients with primary sclerosing cholangitis (PSC) who are treated with ursodeoxycholic acid (UDCA) may have a lower risk of liver transplantation, all-cause death, or biliary tract cancer, according to a study from Japan.
Updates from the SECURE-IBD* registry reveal that treatment with thiopurine, either alone or in combination with tumour necrosis factor inhibitors (TNFis), for inflammatory bowel disease (IBD) was associated with a greater risk of severe COVID-19 compared with TNFis monotherapy.
