Antioxidant Enzyme Activities, Total Sialic Acid, Vitamin, and Trace Element Status in the Patient With Osteoporosis and Osteopenia

Abstract

In this study, osteoporosis (OS), osteopenia (OP), postmenopausal women with osteoporosis (PMOS) and osteopenia (PMOP), and control participants were evaluated for erythrocyte. CAT, GSH-Px, SOD enzyme activities, MDA, GSH, serum phylloquinone, cholecalciferol, retinol, alpha-tocopherol, TSA, TAS, Co, Mn, Fe, Zn, Cu, Se, Ni, Cd, Pb, Mg, Ca, P, K, Cl levels, and the relations of parameters (F-L-BMD, LT-FT-score) were assessed. In this study, element analyses were carried out using ICP-OES and vitamin determination using the HPLC method. Statistical analyses showed that the OS group had significantly lower FBMD (p < 0.001), LBMD (p < 0.001), GSH (p < 0.01), GSH-Px (p < 0.001), CAT (p < 0.001), alpha-tocopherol (p < 0.05), retinol (p < 0.05), cholecalciferol (p < 0.001), phylloquinone (p < 0.01), Se (p < 0.01), Fe (p < 0.05), Cu (p < 0.05), Co (p < 0.001), Zn (p < 0.001), and Mg (p < 0.01) levels than the control group. However, levels of SOD (p < 0.05) and MDA (p < 0.01) are significantly higher than the control group. It was revealed that there is a significant correlation between Mn-L BMD (r = 0.426; p = 0.024), retinol-L BMD (r = 0.502; p = 0.007), cholecalciferol-L BMD (r = - 0.520; p = 0.005), and with OP; also between retinol-L BMD (r = 0.607; p = 0.008) and with PMOS; also between K-F BMD (r = - 0.504; p = 0.009), Co-LT score (r = - 0.432; p = 0.031) and with PMOP. Our study demonstrates that lower retinol, Co, and Mn and increased OSI and K levels are significantly related to decreased L BMD and F BMD status and oxidative stress in OP, PMOS, and PMOP. A deficiency of Zn, Co, Se, cholecalciferol, and phylloquinone can be a risk factor for the progression of OS, OP, PMOS, and PMOP and could have a negative effect on bone density.
