OBJECTIVE
This study was designed to investigate the effect of steroid injection on the blood sugar level in shoulder pain patients with diabetes mellitus. METHOD: Fifteen patients with shoulder pain and diagnosed diabetes mellitus were included. The blood sugar, insulin, cortisol and HbA1c level were measured before and twice (at 24 hours and 1 week) following a intraarticular, intratendinous or intrabursal injection containing triamcinolone. Statistical significance was determined by the paired t-test. RESULTS: The blood sugar, insulin and HbA1c levels had no significant difference between before and after steoid injection (p>0.05). But, the cortisol level significantly fell at 24 hours after steroid injection compared with preinjection level and returned to preinjection level by 1 week after steroid injection (p<0.05). CONCLUSION: One time triamcinolone injection resulted in significant suppression of cortisol level, but it returned to preinjection level after a week. The blood level of sugar, insulin and HbA1c showed no significant change after one time steroid injection.
