Objectives: Specific human leukocyte antigen (HLA) haplotypes are associated with Behçet's disease. Because the effects of HLA-A26 and its combination with HLA-B51 on organ involvement in Behçet's disease have not been well demonstrated, we aimed to examine them.

Methods: This multicentre, cross-sectional, observational study enrolled patients with Behçet's disease who visited Kyoto University Hospital between 2018 and 2021 or Kurashiki Central Hospital between 2006 and 2016 (n = 200). Disease severity was evaluated using the Krause score.

Results: Uveitis and gastrointestinal involvement were observed in 95/196 and 57/167 patients, respectively. The HLA alleles identified were HLA-B51 (n = 52/106), HLA-A26 (n = 25/88), and HLA-B51 and HLA-A26 (n = 6/88). In patients harbouring HLA-B51, the presence of HLA-A26 was associated with higher frequencies of uveitis (P = .03) and coexistence of uveitis and gastrointestinal involvement (P = .002) and higher Krause scores (P = .02). Furthermore, the presence of HLA-A26 was associated with a higher frequency of uveitis in patients with gastrointestinal involvement (P = .001) and gastrointestinal involvement in patients with uveitis (P = .001).

Conclusions: Since specific HLA haplotypes and their combinations are associated with organ involvement, both HLA-A and HLA-B haplotypes should be confirmed when screening for affected organs.

Aim: Snakes exhibit remarkable physiological shifts when their large meals induce robust postprandial growth after prolonged fasting. To understand the regulatory mechanisms underlying this rapid metabolic transition, we examined the regulation of protein synthesis in pythons, focusing on processes driving early postprandial tissue remodeling and growth.

Methods: Using the SUnSET method with puromycin labeling, we measured in vivo protein synthesis in fasting and digesting snakes at multiple post-feeding intervals.

Importance: The D842V platelet-derived growth factor receptor α (PDGFRA) mutation identifies a molecular subgroup of gastrointestinal stromal tumors (GISTs), primarily resistant to standard tyrosine kinase inhibitors and with an overall more indolent behavior. Although functional imaging with 18F-fluorodeoxyglucose-labeled positron emission tomography ([18F]FDG-PET) plays a proven role in GISTs, especially in early assessment of tumor response, less is known about [18F]FDG uptake according to the GIST molecular subtypes.

Objective: To evaluate the degree of [18F]FDG uptake in PDGFRA-mutant GISTs and better define the role of functional imaging in this rare and peculiar subset of GISTs.

Tamoxifen is one of the most frequently used endocrine medications for the treatment of estrogen receptor-positive (ER + ) breast cancer (BC). Unfortunately, tamoxifen resistance (TR) brings more challenges to the clinical treatment, and the mechanisms of TR have not yet been fully clarified. HGF/c-Met is closely associated with cancer metastasis, but whether it is involved in TR remains unclear.

Specialty laboratory testing for chronic abdominal pain in irritable bowel syndrome.

Scand J Gastroenterol

January 2025

Department of Gastroenterology, Hepatology, and Nutrition, Digestive Disease Institute, Cleveland Clinic Foundation, Cleveland, OH, USA.

Background: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder seen by both primary care providers (PCPs) and gastroenterologists, and further diagnostic testing is generally discouraged unless red-flag symptoms are present.

Aims: Examine if advanced serologic testing for chronic abdominal pain in IBS patients followed society-specific guidelines and evaluate the diagnostic accuracy of these tests.

Methods: The study involved a retrospective cross-sectional analysis of adults aged 18 and older who were seen at our institution between 2013 and 2018.

Inflammatory bowel disease (IBD) is increasing among mammals around the world, and domestic dogs are no exception. There is no approved cure for canine IBD with limited treatment options. Novel probiotic bacteria discovery from free-ranging animals for the treatment of IBD in domestic pets can likely yield promising probiotic candidates.
