Abstract

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.
