Drug Response And Metabolism In Crohn's Disease, Aze Wilson
Electronic Thesis and Dissertation Repository
Inflammatory bowel disease (IBD) is an illness of chronic intestinal inflammation comprised of Crohn's disease (CD) and ulcerative colitis (UC). Specialists rely heavily on drugs that target a dysregulated immune system. There is a staggering degree of variation in drug response in CD. Our understanding of drug metabolism and response in IBD is limited. Gaining new insights into IBD-specific modifications of drug metabolism may allow for improved drug efficacy and reduced toxicity. Cytochrome P450 (CYP) 3A4 is the most relevant determinant of drug metabolism and exposure for medications prescribed today. CYP3A4 is highly expressed in the liver, but is also …

Background: Acute Coronary Syndrome (ACS) is a leading cause of morbidity and mortality. Metabolic syndrome and obesity are major risk factors for atherosclerosis and ACS. Dysbiosis plays an important role in metabolic syndrome and obesity. Studies show a markedly increased risk of heart attacks in patients with high levels of the pro-atherogenic metabolite trimethylamine-N-Oxide (TMAO). TMAO is produced by the intestinal microbial flora through metabolism of dietary phospholipids; Gram-negative bacteria (Phylum Proteobacteria) is the major source of TMAO metabolism. Patients with obesity and metabolic syndrome have a defective intestinal tight-junctional (TJ) barrier, which allows paracellular permeation of luminal antigens such …
