Fenofibrate improves liver function and reduces the toxicity of the bile acid pool in patients with primary biliary cholangitis and primary sclerosing cholangitis who are partial responders to Ursodiol.

Clin Pharmacol Ther 2020 Jun 1. Epub 2020 Jun 1.

Yale University School of Medicine, Liver Center, New Haven, CT, USA.

Cholestatic liver diseases result in the hepatic retention of bile acids, causing subsequent liver toxicity. Peroxisome proliferator-activated receptor alpha (PPARα) regulates bile acid metabolism. In this retrospective observational study, we assessed the effects of fenofibrate (a PPARα agonist) therapy on bile acid metabolism when given to patients with PBC and PSC who have had an incomplete response to Ursodiol monotherapy.

The management of gallbladder polyps.

J Visc Surg 2020 May 27. Epub 2020 May 27.

Digestive and transplantation Department, Lille Nord de France University, Claude Huriez Hospital, University Hospital of Lille, rue Michel-Polonovski, 59037 Lille, France.

Neoplastic gallbladder polyps (NGP) are rare; the prevalence in the overall population is less than 10%. NGP are associated with a risk of malignant degeneration and must be distinguished from other benign gallbladder polypoid lesions that occur more frequently. NGP are adenomas and the main risk associated with their management is to fail to detect their progression to gallbladder cancer, which is associated with a particular poor prognosis. Read More

Jiangsu Key Laboratory of Immunity and Metabolism, Department of Pathogenic Biology and Immunology, Laboratory of Infection and Immunity, Xuzhou Medical University, Xuzhou, People's Republic of China.

Cholangiopathies are a group of diseases mainly including primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), biliary atresia (BA), and cholangiocarcinoma (CCA). Very limited treatment options are available for these diseases. Following an injury and exposure to DAMPs (Damage associated molecular patterns) and/or PAMPs (Pathogen-associated molecular patterns), cholangiocytes produce a variety of pro-inflammatory cytokines/chemokines leading to the activation of other innate and also adaptive immune cells.

Anti-programmed cell death-1 and anti-programmed cell death ligand-1 immune-related liver diseases: from clinical pivotal studies to real-life experience.

Expert Opin Biol Ther 2020 May 19:1-13. Epub 2020 May 19.

Medical Oncology Unit, Department of Oncology and Hematology, Policlinico S.Orsola-Malpighi, University of Bologna , Bologna, Italy.

Introduction: Monoclonal antibodies directed against programmed cell death-1 (anti-PD-1) and its ligand (anti-PD-L1) showed a significant efficacy among different immunogenic metastatic tumors such as melanoma, non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC). Between immune-related adverse events (irAEs) dependent on immune checkpoint inhibitors (ICPIs), immune-related liver diseases are uncommon and a definitive diagnosis is not always feasible.

Areas Covered: We revised data from phase II/III clinical trials and real-world retrospective analyses on liver-related adverse events induced by anti-PD-1 (nivolumab/pembrolizumab) and anti-PD-L1 (atezolizumab) in advanced cancer populations (melanoma, NSCLC and RCC). Read More

Fully covered self-expanding metal stents for benign biliary stricture after orthotopic liver transplant: 5-year outcomes.

Gastrointest Endosc 2020 May 14. Epub 2020 May 14.

Department of Gastroenterology and Hepato-pancreatology, Hôpital Erasme, Université Libre de Bruxelles, Belgium.

Background And Aims: Minimally invasive treatments of anastomotic benign biliary stricture (BBS) after orthotopic liver transplantation (OLT) include endoscopic placement of multiple plastic stents or fully covered self-expandable metal stents (FCSEMSs). No multi-year efficacy data are available on FCSEMS treatment after OLT.

Methods: We prospectively studied long-term efficacy and safety of FCSEMS treatment in adults 18 years and older with past OLT, cholangiographically confirmed BBS, and an indication for ERCP with stent placement. Read More

Treatment of Overlap Syndromes in Autoimmune Liver Disease: A Systematic Review and Meta-Analysis.

J Clin Med 2020 May 13;9(5). Epub 2020 May 13.

Liver Center, Autoimmune and Cholestatic Liver Disease Program, Department of Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School, 110 Francis St. Suite 8E, Boston, MA 02215, USA.

The treatment of overlap syndromes is guided by small observational studies whose data have never been synthesized in a rigorous, quantitative manner. We conducted a systematic review and meta-analysis to evaluate the efficacy of available treatments for these rare and morbid conditions. We searched the literature for studies comparing ≥2 therapies for autoimmune hepatitis (AIH)-primary biliary cholangitis (PBC), AIH-primary sclerosing cholangitis (PSC), PBC-PSC, AIH-PBC-PSC, autoimmune cholangitis (AIC), or autoimmune sclerosing cholangitis (ASC) with respect to various clinical outcomes, including biochemical improvement and transplant-free survival.
