Article Abstract

Chronic liver diseases, including non-alcoholic fatty liver disease (NAFLD), cirrhosis, and hepatocellular carcinoma (HCC), continue to be a global health burden with a rise in incidence and mortality, necessitating a need for the discovery of novel biomarkers for HCC detection. This study aimed to identify novel non-invasive biomarkers for these different liver disease states. We performed untargeted metabolomics in plasma (Healthy = 9, NAFLD = 14, Cirrhosis = 10, HCC = 34) and saliva samples (Healthy = 9, NAFLD = 14, Cirrhosis = 10, HCC = 22) to test for significant metabolite associations with each disease state. Additionally, we identified enriched biochemical pathways and analyzed correlations of metabolites between, and within, the two biofluids. We identified two salivary metabolites and 28 plasma metabolites significantly associated with at least one liver disease state. No metabolites were significantly correlated between biofluids, but we did identify numerous metabolites correlated within saliva and plasma, respectively. Pathway analysis revealed significant pathways enriched within plasma metabolites for several disease states. Our work provides a detailed analysis of the altered metabolome at various stages of liver disease while providing some context to altered pathways and relationships between metabolites.

Division of Gastroenterology and Hepatology, Department of Internal Medicine, School of Medicine, The University of Jordan, Jordan University Hospital.

Aim: The purpose of our study was to evaluate the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and its associated risk factors in patients with inflammatory bowel disease (IBD).

Methods: This was a retrospective chart review of patients who underwent treatment for IBD at Jordan University Hospital between January 2013 and 2022. Case finding methods and clinical chart reviews were used to evaluate the clinical profile of patients with IBD.

Bevacizumab for refractory gastrointestinal angiodysplasia: a case report and literature review.

Eur J Gastroenterol Hepatol

August 2025

Department of Gastroenterology and Hepatology, Noordwest Ziekenhuisgroep, Alkmaar.

Currently, symptomatic gastrointestinal (GI) angiodysplasia is treated with argon plasma coagulation (APC) via endoscopic procedures, supplemented with octreotide or thalidomide treatment. However, suboptimal response and side effects are often seen. Bevacizumab, an angiogenesis inhibitor, may provide an alternative systemic therapy for patients with refractory GI angiodysplasia.

Background: Cirrhosis is a leading cause of noncancer deaths in gastrointestinal diseases, resulting in high hospitalization and readmission rates. Early identification of high-risk patients is vital for proactive interventions and improving health care outcomes. However, the quality and integrity of real-world electronic health records (EHRs) limit their utility in developing risk assessment tools.

Objective: To verify the effect of physical exercise on the quality of life of patients with liver cirrhosis (LC).

Methods: the sample included controlled and randomized experimental studies of individuals with LC, at any stage of the disease, over 18 years of age, of both sexes, who performed any type of physical exercise compared to any other intervention or no intervention, with quality of life as the outcome assessed by the Chronic Liver Disease Questionnaire (CLDQ). The search for articles was conducted in 11 databases.
