Magnesium concentrations in plasma, erythrocyte and platelet, and plasma and urine levels of the soluble form of Intercellular Adhesion Molecule-1 (sICAM-1) were evaluated in subjects with insulin dependent diabetes mellitus (IDDM) with or without microalbuminuria, and in a control group of healthy subjects. Using a recently introduced tecnique, we found that magnesium concentrations in platelets in diabetic subjects with microalbuminuria were lower than in diabetics with normal albuminuria (1.859±0.47 vs 2.065±0.62 μmol/ 108 cells; P<0.05). Moreover, IDDM subjects had higher plasma sICAM-1 levels than control subjects; no difference, however, was found between sICAM-1 concentrations in the two groups of diabetics. An inverse correlation was found between intraplatelet magnesium and plasma sICAM-1 levels (r = - 0.64; P <0.05) in the diabetics with microalbuminuria. It is concluded that the reduced intraplatelet magnesium content may contribute to the progression of the vascular complications in IDDM subjects with microalbuminuria.

Abstract
Magnesium concentrations in plasma, erythrocyte and platelet, and plasma and urine levels of the soluble form of Intercellular Adhesion Molecule-1 (sICAM-1) were evaluated in subjects with insulin dependent diabetes mellitus (IDDM) with or without microalbuminuria, and in a control group of healthy subjects. Using a recently introduced tecnique, we found that magnesium concentrations in platelets in diabetic subjects with microalbuminuria were lower than in diabetics with normal albuminuria (1.859±0.47 vs 2.065±0.62 μmol/ 108 cells; P<0.05). Moreover, IDDM subjects had higher plasma sICAM-1 levels than control subjects; no difference, however, was found between sICAM-1 concentrations in the two groups of diabetics. An inverse correlation was found between intraplatelet magnesium and plasma sICAM-1 levels (r = - 0.64; P <0.05) in the diabetics with microalbuminuria. It is concluded that the reduced intraplatelet magnesium content may contribute to the progression of the vascular complications in IDDM subjects with microalbuminuria.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
