Budesonide in previously untreated autoimmune hepatitis

2005

Background: Autoimmune hepatitis (AIH) is a chronic liver disease that is effectively treated with immunosuppressive therapy. Predniso(lo)ne, often in combination with azathioprine, is the basic therapeutic option to induce remission. However, this regimen can cause numerous side effects. The aim of the present study was to evaluate budesonide as a treatment option in the induction of remission in patients with previously untreated AIH. Methods: Between October 1998 and August 1999, 12 patients were treated with 3 mg budesonide thrice daily for 3 months in this open one-arm multicenter phase IIa study. Primary end point was induction of remission indicated by a drop of aspartate aminotransf…

Genetic association analysis identifies variants associated with disease progression in primary sclerosing cholangitis

2018

ObjectivePrimary sclerosing cholangitis (PSC) is a genetically complex, inflammatory bile duct disease of largely unknown aetiology often leading to liver transplantation or death. Little is known about the genetic contribution to the severity and progression of PSC. The aim of this study is to identify genetic variants associated with PSC disease progression and development of complications.DesignWe collected standardised PSC subphenotypes in a large cohort of 3402 patients with PSC. After quality control, we combined 130 422 single nucleotide polymorphisms of all patients—obtained using the Illumina immunochip—with their disease subphenotypes. Using logistic regression and Cox proportiona…

Eine 22-jährige Mutter mit starkem Juckreiz und zunehmendem Ikterus zwei Wochen nach Beginn der hormonalen Kontrazeption

2016

Eine intermittierend auftretende cholestatische Lebererkrankung kann einen angeborenen Defekt im Bereich der Gallensaurentransportproteine offenlegen. Die Episoden konnen durch eine Schwangerschaft oder die Einnahme oraler Kontrazeptiva oder anderer Medikamente ausgelost werden. Wir beschreiben den Fall einer 22-jahrigen Mutter, bei der zwei Wochen nach Beginn der hormonalen Kontrazeption ein zunehmender Ikterus und schwerer Juckreiz auftrat. Bereits einige Monate zuvor hatte sie an Juckreiz im Rahmen einer intrahepatischen Schwangerschaftscholestase gelitten. Die Leberbiopsie zeigte eine Cholestase in unauffalligem Lebergewebe. Die Behandlung mit Ursodesoxycholsaure war nicht erfolgreich. …

Mutational Characterization of the Bile Acid Receptor TGR5 in Primary Sclerosing Cholangitis

2010

Background: TGR5, the G protein-coupled bile acid receptor 1 (GPBAR1), has been linked to inflammatory pathways as well as bile homeostasis, and could therefore be involved in primary sclerosing cholangitis (PSC) a chronic inflammatory bile duct disease. We aimed to extensively investigate TGR5 sequence variation in PSC, as well as functionally characterize detected variants.Methodology/Principal Findings: Complete resequencing of TGR5 was performed in 267 PSC patients and 274 healthy controls. Six nonsynonymous mutations were identified in addition to 16 other novel single-nucleotide polymorphisms. To investigate the impact from the nonsynonymous variants on TGR5, we created a receptor mod…

Extended analysis of a genome-wide association study in primary sclerosing cholangitis detects multiple novel risk loci

2012

Background & Aims: A limited number of genetic risk factors have been reported in primary sclerosing cholangitis (PSC). To discover further genetic susceptibility factors for PSC, we followed up on,a second tier of single nucleotide polymorphisms (SNPs) from a genome-wide association study (GWAS). Methods: We analyzed 45 SNPs in 1221 PSC cases and 3508 controls. The association results from the replication analysis and the original GWAS (715 PSC cases and 2962 controls) were combined in a meta-analysis comprising 1936 PSC cases and 6470 controls. We performed an analysis of bile microbial community composition in 39 PSC patients by 16S rRNA sequencing. Results: Seventeen SNPs representing 1…

Genome-Wide Association Analysis in Primary Sclerosing Cholangitis

2010

Background & Aims We aimed to characterize the genetic susceptibility to primary sclerosing cholangitis (PSC) by means of a genome-wide association analysis of single nucleotide polymorphism (SNP) markers. Methods A total of 443,816 SNPs on the Affymetrix SNP Array 5.0 (Affymetrix, Santa Clara, CA) were genotyped in 285 Norwegian PSC patients and 298 healthy controls. Associations detected in this discovery panel were re-examined in independent case-control panels from Scandinavia (137 PSC cases and 368 controls), Belgium/The Netherlands (229 PSC cases and 735 controls), and Germany (400 cases and 1832 controls). Results The strongest associations were detected near HLA-B at chromosome 6p21…

Elafibranor, an Agonist of the Peroxisome Proliferator-Activated Receptor-alpha and -delta, Induces Resolution of Nonalcoholic Steatohepatitis Withou…

2016

International audience; BACKGROUND & AIMS: Elafibranor is an agonist of the peroxisome proliferator-activated receptor-α and peroxisome proliferator-activated receptor-δ. Elafibranor improves insulin sensitivity, glucose homeostasis, and lipid metabolism and reduces inflammation. We assessed the safety and efficacy of elafibranor in an international, randomized, double-blind placebo-controlled trial of patients with nonalcoholic steatohepatitis (NASH).METHODS: Patients with NASH without cirrhosis were randomly assigned to groups given elafibranor 80 mg (n = 93), elafibranor 120 mg (n = 91), or placebo (n = 92) each day for 52 weeks at sites in Europe and the United States. Clinical and …

Genome-wide association analysis in primary sclerosing cholangitis identifies two non-HLA susceptibility loci

2011

Primary sclerosing cholangitis (PSC) is a chronic bile duct disease affecting 2.4-7.5% of individuals with inflammatory bowel disease. We performed a genome-wide association analysis of 2,466,182 SNPs in 715 individuals with PSC and 2,962 controls, followed by replication in 1,025 PSC cases and 2,174 controls. We detected non-HLA associations at rs3197999 in MST1 and rs6720394 near BCL2L11 (combined P = 1.1 x 10(-16) and P = 4.1 x 10(-8), respectively).

Pregnancy in primary sclerosing cholangitis

2011

Background There is a paucity of data on fertility or pregnancy in patients with primary sclerosing cholangitis (PSC). Objective To assess fertility in PSC by comparing the number of children in a large cohort of PSC patients to healthy controls and to investigate the outcome of pregnancy, as well as the influence of pregnancy on the disease course. Design Case series. Setting Germany. Participants 229 PSC patients and 569 healthy controls were evaluated for the number of children. 17 patients with PSC and at least one pregnancy, or who received a diagnosis of PSC within 6 months after delivery, were included in the more detailed analysis. Main outcome measures Number of children per patien…
