Abstract
- Background Effects of long-term administration of non-steroidal anti-inflammatory drugs (NSAIDs) on the colon have not been well characterized. Aim To investigate colonoscopic findings and prevalence of adverse events following long-term use of NSAIDs. Methods The study included 425 patients (mean 66.4 years) treated for over one year with NSAIDs, and 2125 age- and sex-matched patients without NSAIDs as controls. Eligible candidates were selected by medical record review for underlying diseases, pre-endoscopic symptoms, category of NSAIDs used, and duration of use. We used endoscopy to study lesion characteristics. Results The occurrence rate of colonic lesions or bleeding in the NSAIDs user (13/425, 3.1%) was higher than that in controls (28/2125, 1.3%) ( p = 0.017). Colitis was found in 10 of the 13 patients. The sigmoid colon, descending colon or both (70.0%) was commonly involved, and showed segmental ischemic colitis features in 8 of the 13 patients (61.5%). Among these, duration of use ranged from 1-30 years (mean 7.8). Nine of 13 patients (69.2%) took low-dose aspirin. Conclusion The prevalence of colonic lesions in long-term NSAIDs users is much lower than that of upper gastrointestinal side effects, but higher than that of colonic lesions in non-NSAIDs users. The most common features of NSAIDs-associated colitis were segmental ischeznia. [ABSTRACT FROM AUTHOR]
