One approach to unraveling the genetics of complex inherited disease, such as Crohn's disease, is to search for subclinical disease markers among unaffected family members. We assessed the possible presence, prevalence, and inheritance pattern of sub

Background: Failure of ulcer healing may be critically important to the development of serious gastrointestinal complications in patients on long-term NSAIDs. Aim: To determine the effect of indometacin, celecoxib, a cyclooxygenase-2-specific inhibit

BACKGROUND AND AIMS—Assessing the presence and degree of intestinal inflammation objectively, simply, and reliably is a significant problem in gastroenterology. We assessed faecal excretion of calprotectin, a stable neutrophil specific marker, as a

Prediction of relapse of inflammatory bowel disease has important implications for therapeutic strategies. We assessed whether measurement of intestinal permeability and inflammation could predict relapse of inflammatory bowel disease (IBD).Forty-thr

These studies assessed the gastrointestinal tolerability and cyclooxygenase (COX) selectivity of nimesulide in animals and man. Nimesulide (15 and 30 mg/kg) had no significant 'topical' toxicity in animals as assessed by in vivo mitochondrial morphol

Background The pathogenesis of NSAID-induced gastrointestinal damage is believed to involve a nonprostaglandin dependent effect as well as prostaglandin dependent effects. One suggestion is that the nonprostaglandin mechanism involves uncoupling of m

There is irrefutable evidence that cyclooxygenase-1 (COX-1) inhibition by itself is not the only factor in the development of the gastrointestinal damage of NSAIDs. One suggestion is that the 'topical' effect of NSAIDs is an important initiating fact

PURPOSE: Assessment of inflammation within the ileal pouch to establish a diagnosis of “pouchitis” requires both pouch endoscopy and biopsy because there can be a poor correlation between macroscopic and histologic assessments of inflammation. A

Background: Gastrointestinal symptoms are distressing features of human immunodeficiency virus (HIV) ) infection, and management is often empirical, including withdrawal of dietary lactose. We assessed the prevalence and severity of intestinal disacc

It is suggested that the gastrointestinal toxicity of conventional non-steroid anti-inflammatory drugs (NSAIDs) is due to a 'topical' effect in addition to inhibition of the mucosal constitutive cyclo-oxygenase-1 (COX-1) enzyme. COX-2 selective inhib
