Evaluation of a Ten-Antigen Immunodot Test in Autoimmune Hepatitis and Primary Biliary Cholangitis: Lessons Learned for a Tertiary Care Academic Hospital.

Autoimmune diseases of the liver and biliary tract require timely and accurate diagnosis. This study evaluates the D-tek panel (D-Tek, Mons, Belgium) of 10 immunodot antigens for its effectiveness in diagnosing autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC). We retrospectively analysed serum samples from 111 patients who had undergone routine testing, including indirect immunofluorescence (IIF) and enzyme-linked immunosorbent assays (ELISA), to confirm or exclude autoimmune liver or biliary tract disease.

Drug-induced liver injury related to gene therapy: A new challenge to be managed.

Gene therapy is being successfully developed for the treatment of several genetic disorders. Various methods of gene transfer have been developed to enable the production of the deficient enzyme or protein. One of the most important is adeno-associated virus vectors, which have been shown to be viable for use in in vivo gene therapy.

CDK4/6 inhibitor-induced liver injury: Clinical phenotypes and role of corticosteroid treatment.

Background & Aims: Cyclin-dependent kinase 4/6 (CDK4/6) inhibitors are the cornerstone of systemic therapy for patients with hormone receptor-positive, HER2-negative (HR+/HER2-) metastatic breast cancer. In the various therapeutic studies with CDK4/6 inhibitors, elevations in liver tests were more frequent than in the control groups. The mechanism of CDK4/6 inhibitor-induced liver toxicity is not well understood; moreover, natural history and appropriate management are poorly described.

Prevalence and characteristics of cystic fibrosis liver disease: a study highlighting the lack of histological diagnosis.

Background And Aims: Cystic fibrosis liver disease (CFLD) is the third leading cause of death in patients with cystic fibrosis (CF). We aim to determine the prevalence of CFLD in a cohort of adult patients with CF and to characterise liver involvement in this population highlighting the importance of histological diagnosis.

Methods: We retrospectively studied a cohort of patients with CF.

Liver Decompensation after Bariatric Surgery in the Absence of Cirrhosis.

Purpose: Metabolic dysfunction-associated fatty liver disease-related cirrhosis is possible at the time of bariatric surgery, complicated by further liver decompensation. Hepatic decompensation can also occur in the absence of cirrhosis but the presentation is less clear.

Methods: We analyze the clinical characteristics, histological findings, and management of patients without cirrhosis who developed hepatic decompensation after bariatric surgery in our single tertiary-care hospital.

Immunotherapy and Gene Therapy: New Challenges in the Diagnosis and Management of Drug-Induced Liver Injury.

In the last 5 years, the landscape of oncologic treatment has been deeply modified with the development and use of immune checkpoint inhibitors (ICIs) that exert their antitumoral effect by reverting the exhausted phenotype of tumor-infiltrating lymphocytes. This innovative therapeutic strategy has widely changed the prognosis of some advanced neoplastic diseases such as melanoma and lung cancer, providing durable remission for a significant number of patients. Unfortunately, immune-related adverse events (irAEs), especially ICI-induced hepatitis, may be very severe in some cases, impairing the prognosis of the patient.

Sequential Liver-Kidney Transplantation for Recurrent Liver Cysts Infection in a Patient With Autosomal Dominant Polycystic Kidney Disease: A Case Report.

Autosomal dominant polycystic kidney disease (ADPKD) is the most prevalent hereditary kidney disorder. Liver cysts are the most common extrarenal manifestation of the disease and usually remain asymptomatic. Liver cyst infection is rare, and its treatment is challenging.

Eliminating Hepatitis C Virus From a Prevalent Kidney Transplant Recipient Population: A Single-Center Study in Belgium in the Direct-Acting Antivirals Era.

Background: Direct-acting antivirals (DAAs) have revolutionized the treatment of hepatitis C virus (HCV) infection. Although previous studies have reported positive results with DAAs after kidney transplantation (KT), their impact on the prevalence of HCV viremia (HCVv) in prevalent kidney transplant recipients (KTRs) remains ill defined.

Methods: We retrospectively reviewed the HCV status of all patients followed at Cliniques Universitaires Saint-Luc, Brussels, Belgium, outpatient KT clinic between January 2014 and December 2018.

Chronic liver injury promotes hepatocarcinoma cell seeding and growth, associated with infiltration by macrophages.

Ninety percent of hepatocarcinoma (HCC) develops in a chronically damaged liver. Interactions between non-tumor stromal components, especially macrophages, and cancer cells are still incompletely understood. Our aim was to determine whether a chronically injured liver represents a favorable environment for the seeding and growth of HCC cells, and to evaluate the potential roles of macrophages infiltrated within the tumor.

Aging enhances liver fibrotic response in mice through hampering extracellular matrix remodeling.

Unlabelled: Clinical data identify age as a factor for severe liver fibrosis. We evaluate whether and how aging modulates the fibrotic response in a mouse model. Liver fibrosis was induced by CCl injections (thrice weekly for 2 weeks) in 7 weeks- and 15 months-old mice (young and old, respectively).

Animal Models for Fibrotic Liver Diseases: What We Have, What We Need, and What Is under Development.

Liver fibrosis is part of the wound-healing response to liver damage of various origins and represents a major health problem. Although our understanding of the pathogenesis of liver fibrosis has grown considerably over the last 20 years, effective antifibrotic therapies are still lacking. The use of animal models is crucial for determining mechanisms underlying initiation, progression, and resolution of fibrosis and for developing novel therapies.

Tetrahydro Iso-Alpha Acids and Hexahydro Iso-Alpha Acids from Hops Inhibit Proliferation of Human Hepatocarcinoma Cell Lines and Reduce Diethylnitrosamine Induced Liver Tumor Formation in Rats.

Chronic inflammation plays important role in the pathogenesis of hepatocellular carcinoma (HCC). To date, no antiinflammatory approach has shown its efficacy in preventing HCC occurrence in humans. Because tetra- and hexahydro isoalpha acids (THIAA and HHIAA) from hops elicit antiinflammatory properties, we evaluated these compounds for antitumor effects in vitro in human HCC cell lines (HepG2, Hep3B, Huh7) and in vivo in diethylnitrosamine (DEN)-induced animal model of HCC.

The Ras/MAPK pathway and hepatocarcinoma: pathogenesis and therapeutic implications.

Background: Hepatocellular carcinoma (HCC) is still a major health problem, often diagnosed at an advanced stage. The multikinase inhibitor sorafenib is to date the sole approved systemic therapy. Several signalling pathways are implicated in tumour development and progression.
