Study Title:

Evaluation of small bowel injury in patients with rheumatoid arthritis by capsule endoscopy: effects of anti-rheumatoid arthritis drugs.

Study Abstract

BACKGROUND AND AIM:
The medical treatment of rheumatoid arthritis (RA) includes nonsteroidal anti-inflammatory drugs (NSAIDs), low-dose corticosteroids, and disease-modifying antirheumatic drugs (DMARDs). We evaluated the incidence of small bowel injury in RA patients who were taking anti-RA drugs with or without concomitant NSAIDs by capsule endoscopy.
METHODS:
A total of 28 RA patients who took low-dose corticosteroids and/or DMARDs for more than 1 year were enrolled.
RESULTS:
The incidence of red spots did not differ between the 2 groups: 14 of 16 patients (87.5%) in the NSAID group and 11 of 12 patients (91.7%) in the non-NSAID group. In contrast, the incidence of mucosal breaks was significantly higher in the NSAID group than in the non-NSAID group: mucosal breaks were detected in 13 of 16 patients (81.3%) and 4 of 12 patients (33.3%) in the NSAID and non-NSAID groups, respectively. In the NSAID group, mucosal breaks developed in users of preferential cyclooxygenase-2 inhibitors at a frequency similar to that in users of traditional NSAIDs.
CONCLUSION:
Patients taking anti-RA drugs may have an increased frequency of small bowel injury regardless of NSAID use, and NSAID use may be associated with an increased incidence of severe small bowel injury.
