Characteristics, Trends, and Outcomes of Liver Transplantation for Primary Sclerosing Cholangitis in Female Versus Male Patients
Background. The influence of sex on primary sclerosing cholangitis (PSC), pre- and postliver transplantation (LT) is unclear. Aims are to assess whether there have been changes in incidence, profile, and outcome in LT-PSC patients in Europe with specific emphasis on sex. Methods. Analysis of the European Liver Transplant Registry database (PSC patients registered before 2018), including baseline demographics, donor, biochemical, and clinical data at LT, immunosuppression, and outcome. Results. European Liver Transplant Registry analysis (n = 6463, 32% female individuals) demonstrated an increasing number by cohort (1980-1989, n = 159; 1990-1999, n = 1282; 2000-2009, n = 2316; 2010-2017, n =…
Long-term outcome after living donor liver transplantation compared to donation after brain death in autoimmune liver diseases: Experience from the European Liver Transplant Registry.
Knowledge of living donor liver transplantation (LDLT) for autoimmune liver diseases (AILDs) is scarce. This study analyzed survival in LDLT recipients registered in the European Liver Transplant Registry with autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis (PSC) and the non-autoimmune disorder alcohol-related cirrhosis. In total, 29 902 individuals enrolled between 1998 and 2017 were analyzed, including 1003 with LDLT. Survival from >90 days after LDLT for AILDs in adults was 85.5%, 74.2%, and 58.0% after 5, 10, and 15 years. Adjusted for recipient age, sex, and liver transplantation era, adult PSC patients receiving LDLT showed increased mortality compare…
X Chromosome Contribution to the Genetic Architecture of Primary Biliary Cholangitis
Background & aims: Genome-wide association studies in primary biliary cholangitis (PBC) have failed to find X chromosome (chrX) variants associated with the disease. Here, we specifically explore the chrX contribution to PBC, a sexually dimorphic complex autoimmune disease. Methods: We performed a chrX-wide association study, including genotype data from 5 genome-wide association studies (from Italy, United Kingdom, Canada, China, and Japan; 5244 case patients and 11,875 control individuals). Results: Single-marker association analyses found approximately 100 loci displaying P < 5 × 10-4, with the most significant being a signal within the OTUD5 gene (rs3027490; P = 4.80 × 10-6; odds…
An international genome-wide meta-analysis of primary biliary cholangitis: Novel risk loci and candidate drugs.
[BACKGROUND & AIMS] Primary biliary cholangitis (PBC) is a chronic liver disease in which autoimmune destruction of the small intra-hepatic bile ducts eventually leads to cirrhosis. Many patients have inadequate response to licensed medications, motivating the search for novel therapies. Previous genome-wide association studies (GWAS) and meta-analyses (GWMA) of PBC have identified numerous risk loci for this condition, providing insight into its aetiology. We undertook the largest GWMA of PBC to date, aiming to identify additional risk loci and prioritise candidate genes for in silico drug efficacy screening. [METHODS] We combined new and existing genotype data for 10, 516 cases and 20, 77…
