g per day of chromium as chromium picolinate.Aims To determine if the stress of corticosteroid treatment increases chromium (Cr) losses and if corticosteroid-induced diabetes (steroid diabetes) can be reversed by supplemental chromium.
Methods The effects of corticosteroid treatment on chromium losses of 13 patients 2 days prior to steroid administration and the first 3 days following treatment were determined. Since steroid-induced diabetes was associated with increased chromium losses and insufficient dietary chromium is associated with glucose intolerance and diabetes, we treated three patients with steroid-induced diabetes with 600 g per day of chromium as chromium picolinate.
Results Urinary chromium losses following corticosteroid treatment increased from 155 ± 28 ng/d before corticosteroid treatment to 244 ± 33 ng/d in the first 3 days following treatment. Chromium supplementation of patients with steroid-induced diabetes resulted in decreases in fasting blood glucose 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 when given supplemental chromium.
Conclusions These data demonstrate that corticosteroid treatment increases chromium losses and that steroid-induced diabetes can be reversed by chromium supplementation. Follow-up, double-blind studies are needed to confirm these observations.
