Background: Corticosteroids and non-steroidal anti-inflammatory drugs are widely used for the treatment of rheumatic conditions, but their gastrointestinal damage significantly limits their use. Sigmoid diverticular abscess perforation (SDAP) is a very serious complication of diverticular disease.

Objective: To determine the aetiology of large bowel SDAP in rheumatic conditions.

Methods: 64 patients with SPAD and 320 controls from a similar geographical area and of similar socioeconomic status were studied.

Results: The results showed that independently of rheumatic diagnosis corticosteroid treatment is strongly associated with SDAP (OR 31.9 (95% CI 6.4 to 159.2; p<0.001), and non-steroidal anti-inflammatory drugs only weakly associated (OR 1.8 (95% CI 0.96 to 3.4); p = 0.069). A rheumatic diagnosis is also strongly associated with the development of SDAP (OR 3.5 (95% CI 1.9 to 6.7); p<0.001).

Conclusions: SDAP has serious implications for patients and consumes many healthcare resources. Patients and physicians should be warned of this potential complication.
