Background It has been reported that glucocorticoids (GCs) and non-steroidal anti-inflammatory drugs (NSAIDs) might increase sigmoid diverticulitis perforations (SDPs) for rheumatoid arthritis patients, however, there are few previous reports referring to the relationship between SDPs and GCs in patients with systemic autoimmune diseases. We investigate relationship between SDPs and GCs in patients used GCs for not only rheumatic patients but also other autoimmune disease' sufferer.

SDPs and GCs

Objectives To describe development of SDPs during high dose GC (over PSL 0.8mg/kg equivalent) therapy for systemic autoimmune diseases in our department, additionally reviewing previous reports with regard to the relationship between SDPs and GCs.

Methods 187 patients hospitalized in our department from April 2015 to December 2016 were retrospectively reviewed.

Results Among 187 patients, 61 took high dose GCs, 29 took moderate dose GCs (0.5–0.6mg/kg PSL equivalent), 53 took low dose (less than 0.5mg/kg PSL equivalent), and 29 didn't take GCs. Four patients out of 61 who took high dose GCs developed SDPs (table). Nobody developed SDPs in moderate, low and not any dose GCs group. Case 1–3 took NSAIDs. Case 2 received mPSL pulse therapy (mPSL 1 g x 3 days). Case 1 and 2 developed SDPs within 3 months from initiating GCs. Case 1 recurred SDPs at 17 and 63 months from initiating GCs. Case 2 was prescribed Tacrolimus as a concurrent medication. All four patients were operated to remove the perforated segment, and case 2 and 4 were created artificial anus. Although they were clinically diagnosed as SDPs only case 4 clarified perforation in pathological findings.

Conclusions We should take care of developing SDPs in patients described high dose GCs.
