P126 TRANSVERSE MYELITIS AFTER VEDOLIZUMAB INDUCTION
A 36-year-old woman with ankylosing spondylitis (AS) and a 12 year history of moderate, extensive ulcerative colitis (UC) was evaluated for active symptoms after a 15 month hiatus. Prior therapy included mesalamine and infliximab; the latter led to cli… Continue reading
P060 INFLAMMATION-ASSOCIATED COLONIC LYMPHATIC ARCHITECTURE DISRUPTION IS AMELIORATED BY IRISIN A CHRONIC RODENT MODEL OF IBD
The lymphatics are the main transport of lymph (containing fluid, macromolecules, and immunological components such as cells and cytokines) from the parenchymal tissues to the lymph nodes. Inflammation-induced lymphangiogenesis and lymphatic dysfunctio… Continue reading
P124 THE UBIQUITIN EDITING ENZYME A20 LINKS INFLAMMATION AND COLITIS ASSOCIATED CANCER
Inflammatory bowel disease (IBD) patients are at increased risk of colorectal cancer (CRC)1. Tumor initiating events in colitis-associated cancers (CACs) differ significantly from sporadic CRC2. In CACs, hyperactivity of wnt/beta-catenin signaling typi… Continue reading
P059 INDOLEAMINE 2,3-DIOXYGENASE 1 EXPRESSION PROMOTES EPITHELIAL SECRETORY CELL DIFFERENTIATION VIA ARYL HYDROCARBON RECEPTOR
In mouse models of IBD, the tryptophan metabolizing enzyme indoleamine 2,3-dioxygenase 1 (IDO1) has been shown to limit disease severity. Our studies indicate that intestinal epithelial cells are an important source of IDO1 expression in these conditio… Continue reading
P122 THE ROLE OF PTPN2 SNP IN THE PATHOGENESIS OF FIBROSIS IN CROHN’S DISEASE
We identified altered IL-6-induced Jak1-dependent STAT3 phosphorylation in human ileal subepithelial myofibroblasts (SEMF) of patients with stricturing Crohn’s disease. This resulted in co-localization of pSTAT3(Y705) to Rab5+ signaling endosomes alo… Continue reading
P058 INCREASES IN HEMOGLOBIN ARE ASSOCIATED WITH A DECREASED RISK FOR COLORECTAL CANCER IN VETERAN’S AFFAIRS INFLAMMATORY BOWEL DISEASE PATIENTS
Colorectal cancer (CRC) has long been associated with inflammatory bowel disease (IBD), thought to be due to chronic mucosal inflammation. With newer IBD treatments, the incidence of CRC is decreasing, possibly due to improved therapies or improved tre… Continue reading
P120 THE ROLE OF MICROBIOTA AND MACROPHAGES DURING COLITIS IN TUMOR NECROSIS FACTOR RECEPTOR 1 (TNFR1) AND IL-10 DEFICIENT MOUSE MODEL
Inflammatory bowel disease (IBD) remain major clinical challenges and are currently incurable. Tumor necrosis factor (TNF) is a major therapeutic target in IBD, and TNFR1 polymorphisms have been described in IBD patients. Interleukin 10 (IL-10) recepto… Continue reading
P057 IMPROVED QUALITY OF CARE AND QUALITY OF LIFE FOR IBD PATIENTS USING MOBILE BASED REMOTE MONITORING PLATFORM: A RANDOMIZED CONTROL TRIAL
The recurrent and debilitating nature of Inflammatory Bowel Disease (IBD) makes affected patients ideal candidates to assess the therapeutic potential of a digital intervention for long-term patient management. HealthPROMISE is an innovative software p… Continue reading
P118 THE RISK OF DIARRHEA AND COLITIS IN PATIENTS WITH ADVANCED MELANOMA UNDERGOING IMMUNE-CHECKPOINT INHIBITOR THERAPY
Anti-cytotoxic-T-lymphocyte associated antigen-4 (anti-CTLA4), and anti-programmed cell death 1 (anti-PD1) immunotherapies are considered first-line treatments for advanced melanoma. However, the use of these agents is limited by gastrointestinal toxic… Continue reading
P056 IMPLEMENTING MASS CYTOMETRY AS A TOOL FOR INFLAMMATORY BOWEL DISEASE RESEARCH
An expanding range of therapeutics have been approved or are under development for IBD. However, objective readouts of treatment efficacy are still lacking, often relying on partially subjective clinical endpoints (CDAI). High-dimensional mass cytometr… Continue reading
