title: Comparative Study of Serum Copper, Iron, Magnesium, and Zinc in Type 2 Diabetes-Associated Proteinuria.
abstract: Trace element (TE) disturbances are well noted in type 2 diabetes mellitus (T2DM) and its associated complications. In present study, the effect of proteinuria on serum copper (Cu), iron (Fe), magnesium (Mg), and zinc (Zn) in T2DM patients with and without proteinuria was seen. Total subjects were aged between 30 and 90 years; 73 had proteinuria, 76 had T2DM with proteinuria, 76 had T2DM, and 75 were controls. Serum Cu(II), Fe(III), Mg(II), and Zn(II) were assayed by inductively coupled plasma optical emission spectrometer (ICP-OES). Urinary albumin estimation was performed by turbidimetric method. Other biochemical parameters were analyzed by ROCHE Module COBAS 6000 analyzer. Statistical analysis was performed using analysis of variance (ANOVA) at P<0.0001 followed by t test. Pearson correlation was applied to estimate the effect of proteinuria on TE. Serum Cu(II) level was increased in T2DM patients with proteinuria while Fe(III) was found elevated in T2DM (P<0.0001) compared to control groups. Zn(II) and Mg(II) were significantly low in proteinuria, T2DM with proteinuria, and T2DM (P<0.0001) compare to controls. Serum Cu(II) showed strong positive association with albumin creatinine ratio (ACR) in T2DM with proteinuria group and T2DM group (P<0.01). Fe(III) was positively and Zn(II) was negatively associated with ACR at P<0.10, in T2DM with proteinuria group. Mg(II) was negatively linked with ACR P<0.01 in proteinuria, T2DM with proteinuria, and T2DM group. TE were observed more disturbed in T2DM with proteinuria group, thus considered to be the part of T2DM routine checkup and restricts the disease towards its progression.
