Oxidative Stress Parameters, Trace Elements, and Lipid Profile in Iranian Patients with Gaucher Disease

Abstract

Gaucher disease (GD) is most frequent disorder of glycolipid storage. The glucosylceramide accumulation might lead to oxidative stress and changes in lipid profile. Regarding the main role of trace elements in hematopoiesis and oxidative stress, this study was aimed to evaluate the zinc and copper levels, three oxidative stress parameters, and lipid profile in GD. Thirty-three patients with GD along with 64 age- and sex-matched healthy controls participated in the study. The levels of zinc and copper were determined using atomic absorption/flame emission spectrophotometer. Malondialdehyde level was measured using HPLC. Total antioxidant capacity (TAC), catalase activity, and lipid profile were assessed using colorimetric methods. Data were analyzed using SPSS software version 16.0. Significant decrease in the serum levels of Zn (p < 0.001) and Cu (p < 0.001) was observed in patients with GD compared to controls. Subjects in control group showed significantly higher levels of TAC than patients with GD (p < 0.001). In contrast, plasma concentration of malondialdehyde was insignificantly higher in patients with GD than controls (p = 0.06). There was a direct correlation between TAC and hemoglobin concentration (p = 0.035; r = 0.369) in patients with GD. Furthermore, the calculated area under receiver operating characteristic curve for HDL cholesterol was equal to 0.938. The results showed that both zinc and copper levels decreased in patients with GD. Patients with GD showed decreased serum content of TAC. It was found that improving the deficiency of zinc and copper by supplementing them could be useful in management of patients with GD.
