Genome-wide meta-analyses identify three loci associated with primary biliary cirrhosis.
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 × 10−11, odds ratio (OR) = 1.46), IRF5-TNPO3 (P = 2.8 × 10−10, OR = 1.63) and 17q12-21 (P = 1.7 × 10−10, OR = 1.38).
ELITA consensus statements on the use of DAAs in liver transplant candidates and recipients
International audience; The advent of safe and highly effective direct-acting antiviral agents (DAAs) has had huge implications for the hepatitis C virus (HCV) transplant field, and changed our management of both patients on the waiting list and those with HCV graft re-infection after liver transplantation (LT). When treating HCV infection before LT, HCV re-infection of the graft can be prevented in nearly all patients. In addition, some candidates show a remarkable clinical improvement and may be delisted. Alternatively, HCV infection can be treated post-LT either soon after the transplant, taking advantage of the removal of the infected native liver, or at the time of disease recurrence, …
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…
Delisting of liver transplant candidates with chronic hepatitis C after viral eradication: A European study
Background & Aims: All oral direct acting antivirals (DAA) have been shown to improve the liver function of patients with decompensated cirrhosis but it is presently unknown whether this clinical improvement may lead to the delisting of some patients. The aim of this study was to assess if and which patients can be first inactivated due to clinically improvement and subsequently delisted in a real life setting. Methods: 103 consecutive listed patients without hepatocellular carcinoma were treated with different DAA combinations in 11 European centres between February 2014 and February 2015. Results: The cumulative incidence of inactivated and delisted patients by competing risk analysis…
