[Magnesium supplementation to patients with type II diabetes].
The purpose of this study was to evaluate Mg status by nuclear magnetic resonance spectroscopy in a group of well-regulated non-insulin-dependent diabetic (NIDDM) patients without angiopathy. Furthermore, to investigate the effect of Mg supplementation on markers of diabetic control, hemostatic function, platelet reactivity and endothelial function in the same patient population. A double-blinded, placebo-controlled and randomized crossover study was carried out, with two 8-weeks treatment periods (360 mg Mg/day) separated by a 4-weeks wash-out period. 11 well-regulated NIDDM patients participated in the study. Eight weeks of Mg supplementation significantly raised the level of free intracellular Mg in the diabetic patients (157.35 +/- 16.53 vs. 197.49 +/- 27.60 microM; p < 0.01). No changes were observed neither in plasma level of von Willebrand factor antigen, fibrinogen and fibronectin nor in platelet release of thromboxane B2 (TxB2). Similarly, markers of diabetic regulation, HbA1c and fructosamine, showed no significant changes. These results suggest that even well regulated NIDDM patients have marked Mg deficiency. Restoring this deficiency had no effect on diabetic control, markers of platelet reactivity, hemostatic function and endothelial function.
