Abstract:

Objective: To explore the type and frequency of the unwanted effects following use of non-steroidal antiinflammatory drugs (NSAIDs) and antibiotics in a gastroenterological out-patient setting.

Methods: We analyzed a gastroenterological database which includes 151 inflammatory bowel disease (IBD) patients followed between January 2008 and December 2009. The key-words included NSAIDs and antibiotics.

Results: Of 19 cases treated with NSAIDs, 8 displayed convincing evidence linking them with the subsequent development of IBD. Of 44 antibiotic mentions, 7 documents alluded to macrolide prescriptions, which were followed by induction or relapse of IBD in 5; all of the newly diagnosed cases of IBD were endoscopically proven, and one ran a fulminant course requiring emergency colectomy; 4 of 5 prescriptions of amoxycillin/clavulanic acid were accompanied by toxicity (three hepatitides and one reactivated IBD). Overall, the frequency of unwanted effects was 36% for both NSAIDs and antibiotics.

Conclusion: We suggest that NSAIDs and antibiotics (specifically of the macrolide structure) can induce gut and hepatic damage, significantly enhancing co-morbidities in gastroenterologic out-patients, with break of cost-containment guidelines. Therefore, caution is advisable in prescribing NSAIDs and antibiotics in this setting. Though retrospective and possibly biased, the current data coincide with both bench work and epidemiological evidence.
