Severe liver disease resembling PSC in mice with K5-Cre mediated deletion of Krüppel-like factor 5 (Klf5).

Transgenic Res 2021 Jun 11. Epub 2021 Jun 11.

Department of Medical Biochemistry and Biophysics, Karolinska Institutet, 171 77, Stockholm, Sweden.

Chronic cholestatic liver diseases including primary sclerosing cholangitis (PSC) present a complex spectrum with regards to the cause, age of manifestation and histopathological features. Current treatment options are severely limited primarily due to a paucity of model systems mirroring the disease. Here, we describe the Keratin 5 (K5)-Cre; Klf5 mouse that spontaneously develops severe liver disease during the postnatal period with features resembling PSC including a prominent ductular reaction, fibrotic obliteration of the bile ducts and secondary degeneration/necrosis of liver parenchyma.

Immunoglobulin G4-related disease in gastroenterology.

Vnitr Lek 2021 ;67(2):76-83

IgG4-related disease is a recently defined clinical entity that can manifest itself in any organ. The most common gastrointestinal manifestations are diseases of the pancreas (autoimmune pancreatitis type 1) and biliary tree (IgG4-associated cholangitis); involvement of liver parenchyma is uncommon and the affection of tubular organs is very rare. IgG4-related pancreatitis and cholangitis can mimic malignancies in their clinical presentation. Read More

Fibrotic Events in the Progression of Cholestatic Liver Disease.

Cells 2021 May 5;10(5). Epub 2021 May 5.

Department of Immunology, Ophthalmology & ENT, Complutense University School of Medicine, 28040 Madrid, Spain.

Cholestatic liver diseases including primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are associated with active hepatic fibrogenesis, which can ultimately lead to the development of cirrhosis. However, the exact relationship between the development of liver fibrosis and the progression of cholestatic liver disease remains elusive. Periductular fibroblasts located around the bile ducts seem biologically different from hepatic stellate cells (HSCs). Read More

We Are Not Immune: Racial and Ethnic Disparities in Autoimmune Liver Diseases.

Hepatology 2021 May 31. Epub 2021 May 31.

USC Research Center for Liver Diseases, Keck School of Medicine, University of Southern California, Los Angeles California, USA.

Autoimmune liver diseases are attributed to a complex interplay of biologic, acquired, and environmental factors. Increased prevalence, later stage of presentation, worse response to standard therapy, and transplant-related disparities have all been reported in racial and ethnic minorities such as Black and Latinx patients with autoimmune liver diseases. While biology and inherited genetic predispositions may partly explain these disparities, definitive and universal genetic variations underlying these differences in outcomes have not been defined.

Department of Gastroenterology, Gastrointestinal Oncology, and Endocrinology, University Medical Center Goettingen, Goettingen, Germany.

BACKGROUND Immunoglobulin (Ig) G4-related disease is a rare disease of unknown pathophysiology, which can affect multiple organs leading to tissue fibrosis and organ failure. The present case report describes a patient with systemic IgG4-related disease (IgG4-RD) that occurred over a 1-year period and affected multiple organs at different times. Imaging studies, interventional procedures, changes in laboratory parameters, and histopathology demonstrate the novel and known aspects of this disease before and during prednisolone monotherapy and in combination with azathioprine.

Collagen proportionate area correlates with histological stage and predicts clinical events in primary sclerosing cholangitis.

Liver Int 2021 May 29. Epub 2021 May 29.

Sheila Sherlock Liver Centre, Royal Free London NHS Foundation Trust and UCL Institute for Liver and Digestive Health, University College of London, London, United Kingdom.

Background & Aims: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease in need of accurate biomarkers for stratification and as surrogates for clinical endpoints in trials. Quantitative liver fibrosis assessment by collagen proportionate area (CPA) measurement has been demonstrated to correlate with clinical outcomes in chronic hepatitis C, alcohol-related and non-alcoholic fatty liver disease. We aimed to investigate the ability of CPA to quantify liver fibrosis and predict clinical events in PSC. Read More

Autologous Hematopoietic Stem Cell Transplantation for Liver Transplant Recipients With Recurrent Primary Sclerosing Cholangitis: A Pilot Study.

Transplantation 2021 May 25. Epub 2021 May 25.

Multi Organ Transplant Program, University Health Network, Toronto, ON, Canada. Blood and Marrow Transplant Program, The Ottawa Hospital, Ottawa, ON, Canada. Department of Pathology, University of Pittsburgh, Pittsburgh, PA. Department of Medical Imaging, University Health Network, Toronto, ON, Canada. Ottawa Stem Cell Program, Canadian Blood Services, Ottawa, ON, Canada.

Background: Primary sclerosing cholangitis (PSC) is an indication for liver transplantation, but recurrence after liver transplantation is associated with poor outcomes often requiring repeat transplantation. We investigated whether autologous hematopoietic stem cell transplantation (aHSCT) could be used to stop progression of recurrent PSC and promote operational tolerance.

Methods: Twelve patients with recurrent PSC were fully evaluated and 5 were selected for aHSCT. Read More

Biomarkers in autoimmune pancreatitis and immunoglobulin G4-related disease.

World J Gastroenterol 2021 May;27(19):2257-2269

Department of Gastroenterology and Hepatology, Kindai University Faculty of Medicine, Osaka-Sayama 589-8511, Japan.

Solitary organ autoimmune disorders, formerly known as autoimmune pancreatitis (AIP), autoimmune sialadenitis, and autoimmune sclerosing cholangitis, are now considered organ-specific manifestations of systemic immunoglobulin G4-related disease (IgG4-RD). AIP and IgG4-RD are characterized by elevated serum concentration of IgG4 antibody (Ab), accumulation of IgG4-expressing plasmacytes in the affected organs, and involvement of multiple organs. It is well established that enhanced IgG4 Ab responses are a hallmark of AIP and IgG4-RD for diagnosis and monitoring disease activity. Read More

Altered faecal microbiome and metabolome in IgG4-related sclerosing cholangitis and primary sclerosing cholangitis.

Gut 2021 May 25. Epub 2021 May 25.

Division of Gastroenterology and Hepatology, Key Laboratory of Gastroenterology and Hepatology, Ministry of Health, State Key Laboratory for Oncogenes and Related Genes, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai Institute of Digestive Disease, Shanghai, China

Objective: Multiple clinical similarities exist between IgG4-related sclerosing cholangitis (IgG4-SC) and primary sclerosing cholangitis (PSC), and while gut dysbiosis has been extensively studied in PSC, the role of the gut microbiota in IgG4-SC remains unknown. Herein, we aimed to evaluate alterations of the gut microbiome and metabolome in IgG4-SC and PSC.

Design: We performed 16S rRNA gene amplicon sequencing of faecal samples from 135 subjects with IgG4-SC (n=34), PSC (n=37) and healthy controls (n=64). Read More
