Blood Viscosity, Lipid Profile, and Lipid Peroxidation in Type-1 Diabetic Patients with Good and Poor Glycemic Control

BACKGROUND: In diabetic patients, persistent hyperglycemia and poor glycemic control cause disturbances of lipid profiles, especially an increased production of oxygen free radicals. Lipid peroxidation has been considered to be a pathogenic factor of diabetic complications in Type-1 Diabetes mellitus. AIMS: The aim of the present study was to investigate the effect of glycemic control on blood viscosity, lipid profile, and lipid peroxidation in Type-1 Diabetic subjects. MATERIALS AND METHODS: The study included three groups; Group-I (age-matched healthy control subjects, n = 50), Group-II (Type-1 Diabetics with good glycemic control, n = 10), and Group-III (Type-1 Diabetics with poor glycemic control, n = 15). The Type 1 diabetic patients with duration of diabetes for more than 5 years were taken. Blood samples of all subjects were analyzed for all biochemical, hematological, and oxidative stress parameters. RESULTS: The Erythrocyte malondialdehyde level was non-significantly changed (P = NS) in group–II patients but significantly increased (P < 0.001) in group-III patients, and no significant changes were found (P = NS) in Blood viscosity of both the groups (group-II and group-III), as compared to healthy control subjects (group-I). CONCLUSIONS: Our findings suggest that the monitoring of Oxidative stress and Blood Viscosity in poorly controlled Type-1 diabetic patients may be very useful marker of diabetic complications.
