Reversal of corticosteroid-induced diabetes mellitis with supplemental chromium

Aims To determine if the stress of corticosteroid treatment increases chrom ium (Cr) losses and if corticosteroid-induced diabetes (steroid diabetes) c an be reversed by supplemental chromium. Methods The effects of corticosteroid treatment on chromium losses of 13 pa tients 2 days prior to steroid administration and the first 3 days followin g treatment were determined. Since steroid-induced diabetes was associated with increased chromium losses and insufficient dietary chromium is associa ted with glucose intolerance and diabetes, we treated three patients with s teroid-induced diabetes with 600 mu g per day of chromium as chromium picol inate. Results Urinary chromium losses following corticosteroid treatment increase d from 155 +/- 28 ng/d before corticosteroid treatment to 244 +/- 33 ng/d i n the first 3 days following treatment. Chromium supplementation of patient s with steroid-induced diabetes resulted in decreases in fasting blood gluc ose values from greater than 13.9 mmol/l (250 mg/dl) to less than 8.3 mmol/ l (150 mg/dl). Hypoglycaemic drugs were also reduced 50% in all patients wh en given supplemental chromium. Conclusions These data demonstrate that corticosteroid treatment, increases chromium losses and that steroid-induced diabetes can be reversed by chrom ium supplementation. Follow-up, double-blind studies are needed to confirm these observations.
