PSC and colitis: A complex relationship.
Hepatology
January 2025
I. Department of Medicine, University Medical Center Hamburg-Eppendorf, 20246 Hamburg, Germany.
Primary sclerosing cholangitis is one of the most challenging conditions in hepatology, and due to our limited understanding of its pathogenesis, no causal therapies are currently available. While it was long assumed that a minority of people with IBD also develop PSC, which is sometimes labeled an extraintestinal manifestation of IBD, the clinical phenotype, genetic and intestinal microbiota associations strongly argue for PSC-IBD being a distinct form of IBD, existing alongside ulcerative colitis and Crohn's disease. In fact, the liver itself could contribute to intestinal pathology, clinically overt in 60 - 80 % of patients.

Food-Drug Interaction (FDI) refers to the phenomenon where food affects the pharmacokinetic or pharmacodynamic characteristics of a drug, significantly altering the drug's absorption rate or absorption extent. These Interactions are considered as a primary determinant in influencing the bioavailability of orally administered drugs within the gastrointestinal tract. The impact of food on drug absorption is complex and multifaceted, potentially involving alterations in gastrointestinal physiology, increases in splanchnic blood flow rates, and shifts in the gut microbiota's composition.

United European Gastroenterol J
January 2025
Sheba Medical Center, Institute of Gastroenterology, Ramat-Gan, Israel.
Background: The Montreal classification has been widely used in Crohn's disease since 2005 to categorize patients by the age of onset (A), disease location (L), behavior (B), and upper gastrointestinal tract and perianal involvement. With evolving management paradigms in Crohn's disease, we aimed to assess the performance of gastroenterologists in applying the Montreal classification.
Methods: An online survey was conducted among participants at an international educational conference on inflammatory bowel diseases.
Intestinal distension induced by luminal D-allulose promotes GLP-1 secretion in male rats.
Endocrinology

Laboratory of Nutritional Biochemistry, Graduate School of Agriculture, Hokkaido University, Sapporo 060-8589, Japan.
The secretion of glucagon-like peptide-1 (GLP-1) is promoted by various nutrients, and glucose and fructose stimulate GLP-1 secretion via intracellular metabolism. D-Allulose (allulose), a non-metabolizable epimer of D-fructose, is also effective in stimulating GLP-1 secretion, although its underlying mechanism remains unclear. We previously observed intestinal distension after the oral administration of allulose, accompanied by increased GLP-1 secretion in rats, possibly because of the low or slow absorbability of allulose.

The widespread prevalence of colorectal cancer and its high mortality rate emphasize the urgent need for more effective therapies. When developing new drug products, a key aspect is ensuring that sufficiently high concentrations of the active drug are reached at the site of action. Drug transporters and drug-metabolizing enzymes can significantly influence the absorption and local accumulation of drugs in intestinal tissue.
