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…

International audience; BACKGROUND & AIMS: We investigated the effectiveness of the protease inhibitors peginterferon and ribavirin in treatment-experienced patients with hepatitis C virus (HCV) genotype 1 infection and cirrhosis. METHODS: In the Compassionate Use of Protease Inhibitors in Viral C Cirrhosis study, 511 patients with HCV genotype 1 infection and compensated cirrhosis who did not respond to a prior course of peginterferon and ribavirin (44.3% relapsers or patients with viral breakthrough, 44.8% partial responders, and 8.0% null responders) were given either telaprevir (n = 299) or boceprevir (n = 212) for 48 weeks.

Dense genotyping of immune-related disease regions identifies nine new risk loci for primary sclerosing cholangitis

2013

To access publisher's full text version of this article click on the hyperlink at the bottom of the page Primary sclerosing cholangitis (PSC) is a severe liver disease of unknown etiology leading to fibrotic destruction of the bile ducts and ultimately to the need for liver transplantation. We compared 3,789 PSC cases of European ancestry to 25,079 population controls across 130,422 SNPs genotyped using the Immunochip. We identified 12 genome-wide significant associations outside the human leukocyte antigen (HLA) complex, 9 of which were new, increasing the number of known PSC risk loci to 16. Despite comorbidity with inflammatory bowel disease (IBD) in 72% of the cases, 6 of the 12 loci sh…

Longterm Risk of Solid Organ De Novo Malignancies After Liver Transplantation: A French National Study on 11,226 Patients

2018

IF 3.756; International audience; De novo malignancies are one of the major late complications and causes of death after liver transplantation (LT). Using extensive data from the French national Agence de la Biomédecine database, the present study aimed to quantify the risk of solid organ de novo malignancies (excluding nonmelanoma skin cancers) after LT. The incidence of de novo malignancies among all LT patients between 1993 and 2012 was compared with that of the French population, standardized on age, sex, and calendar period (standardized incidence ratio; SIR). Among the 11,226 LT patients included in the study, 1200 de novo malignancies were diagnosed (10.7%). The risk of death was app…

2016

International audience; BACKGROUND:We investigated whether sirolimus-based immunosuppression improves outcomes in liver transplantation (LTx) candidates with hepatocellular carcinoma (HCC).METHODS:In a prospective-randomized open-label international trial, 525 LTx recipients with HCC initially receiving mammalian target of rapamycin inhibitor-free immunosuppression were randomized 4 to 6 weeks after transplantation into a group on mammalian target of rapamycin inhibitor-free immunosuppression (group A: 264 patients) or a group incorporating sirolimus (group B: 261). The primary endpoint was recurrence-free survival (RFS); intention-to-treat (ITT) analysis was conducted after 8 years. Overal…

2010

Abstract Background The potential anti-cancer effects of mammalian target of rapamycin (mTOR) inhibitors are being intensively studied. To date, however, few randomised clinical trials (RCT) have been performed to demonstrate anti-neoplastic effects in the pure oncology setting, and at present, no oncology endpoint-directed RCT has been reported in the high-malignancy risk population of immunosuppressed transplant recipients. Interestingly, since mTOR inhibitors have both immunosuppressive and anti-cancer effects, they have the potential to simultaneously protect against immunologic graft loss and tumour development. Therefore, we designed a prospective RCT to determine if the mTOR inhibito…

Liver stiffness measurement by vibration-controlled transient elastography improves outcome prediction in primary biliary cholangitis

2022

BACKGROUND & AIMS: Liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) has been shown to predict outcomes of patients with primary biliary cholangitis (PBC) in small-size studies. We aimed to validate the prognostic value of LSM in a large cohort study. METHODS: We performed an international, multicentre, retrospective follow-up study of 3,985 patients with PBC seen at 23 centres in 12 countries. Eligibility criteria included at least 1 reliable LSM by VCTE and a follow-up ≥ 1 year. Independent derivation (n = 2,740) and validation (n = 568) cohorts were built. The primary endpoint was time to poor clinical outcomes defined as liver-related complications,…

Risk factors of de novo malignancies after liver transplantation: a French national study on 11004 adult patients.

2021

International audience; Background: After liver transplantation (LT),de novo malignancies are one of the leading causes of late mortality. The aim of the present retrospective study was to identify the risk factors of de novo malignancies in a large cohort of LT recipients in France, using Fine and Gray competing risks regression analysis.Methods: The study population consisted in 11004 adults transplanted between 2000 and 2013, who had no history of pre-transplant malignancy, except primary liver tumor. A Cox model adapted to the identification of prognostic factors (competitive risks) was used.Results: From the entire cohort, one (or more)de novo malignancy was reported in 1480 L T recipi…
