Erythrocyte and fasting plasma magnesium were assayed by a dyebinding colorimetric method using the metallochromic dye, Calmagite, in 51 diabetic Nigerians and 25 controls. Erythrocyte magnesium concentrations were similar in the diabetics and the controls. Fasting plasma magnesium concentrations were significantly lower only in insulin-treated diabetics as compared to controls. No significant correlations were observed between fasting plasma glucose concentrations and either plasma or erythrocyte magnesium concentrations in the diabetic groups. Also, no significant correlation was found between erythrocyte magnesium and plasma magnesium concentrations. However, erythrocyte magnesium concentrations were directly related to age while plasma magnesium concentrations were directly related to duration of diabetes in all diabetics. Erythrocyte and plasma magnesium concentrations were not significantly affected by sex and degree of plasma glucose control. These results suggest that insulin-treated black African diabetics may develop hypomagnesaemia which is not associated with depletion of the erythrocyte content of magnesium.

Diabetic nephropathy (DN) is the most common microvascular complication observed in patients with type-2 diabetes mellitus. Furthermore, magnesium (Mg) deficiency is a common problem in diabetic patients. In this study, we estimated the levels of Mg, which is an important trace element and pro-oxidant marker, and then evaluated the association between serum Mg and pro-oxidants in patients with DN. In the present study, 200 patients were enrolled and were divided into two groups. The control and DN groups consisted of 100 healthy individuals and 100 patients with DN, respectively. Serum Mg, total anti-oxidant capacity (TAC), and superoxide dismutase (SOD) levels were estimated using the Calmagite, Koracevic, and Marklund and Marklund methods, respectively. Glutathione (GSH) and malondialdehyde (MDA) levels were estimated using the Tietze F and Jean CD method, respectively. Mg levels were found to be significantly decreased in the DN group in comparison to the control group. Anti-oxidant markers were statistically significantly reduced (P <0.001), whereas MDA levels were statistically significantly elevated (P <0.001) in the DN group compared to the control group. There was a significant positive association of Mg with TAC, SOD, and GSH. A statistically significant negative association of Mg with MDA (r = -0.302, P <0.001, n = 100) was also observed. An apparent relationship was observed between hypomagnesemia and oxidative stress in patients with DN. Lower levels of Mg and oxidative stress were also strongly linked.
