Abstract/OtherAbstract:
Abstract β-Thalassemia (β-thal) is a genetic disorder, representing a major health problem in Algeria. It is associated with altered lipid levels and a state of oxidative stress that can lead to cardiac complications and premature death. We examined the plasma lipid profile and redox status of 46 patients with β-thal major (β-TM) and β-thal intermedia (β-TI) compared to 36 healthy subjects. Plasma lipids including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were investigated. Oxidative status was evaluated by measuring malondialdehyde (MDA), reduced glutathione (GSH) and catalase (CAT) activity. The potential relationships between these parameters and the hemoglobin (Hb) blood concentrations, serum ferritin, duration and frequency of transfusion, splenectomy as well as age, were examined. Our data indicated that the study patients were under increased state of oxidative stress associated with hypertriglyceridemia, and hypocholesterolemia. The CAT activity was negatively correlated with Hb concentration and LDL-C/TG ratio and positively with years of transfusion. The elevated TC/HDL-C ratio particularly in β-TM patients who were younger, correlated positively with ferritinemia and triglyceride levels and suggested an increased coronary risk. This heightened risk state should lead to the inclusion of this index (TC/HDL-C) in clinical management, particularly in splenectomized patients.
