Abstract


Objective. We examined the effects of oral antidiabetics andinsulin/insulin analogs over lipid parameters for the firsttime in Turkish type 2 diabetic (T2DM) patients. Methods.A total of 312 T2DM subjects were included within 4 studygroups (sulphonylurea, biguanide, insulin/insulin analogs,sulphonylurea+biguanide) in this retrospective study. Thedemographic, biochemical and clinical data of the patientswere evaluated and the study groups were compared for allthe variables. The biochemical and lipid parameters were examinedin pairs for their correlations for each study group.Results. Body mass index (BMI) was found to be lower inthe insulin/insulin analogs group in comparison to the biguanideand sulphonylurea+biguanide groups (p < 0.01); systolicblood pressure (SBP) was found to be lower in the insulin/insulin analog group in comparison to the sulphonylurea,sulphonylurea+biguanide and biguanide groups (p < 0.05);diastolic blood pressure (DBP) was found to be lower in theinsulin/insulin analog group in comparison to the biguanidegroup (p<0.05). No difference was found for total-cholesterol,triglyceride, HDL-cholesterol and LDL-cholesterol amongthe study groups (p>0.05). Fasting blood glucose and HbA1clevels were found to be lower in the biguanide group whencompared to the sulphonylurea and insulin/insulin analogs(p<0.001). In all study groups a positive correlation wasfound between blood glucose and HbA1c levels (p<0.001). Aweak positive correlation was observed between blood glucoseand triglyceride (p<0.05) and HbA1c and LDL-cholesterol(p<0.05). Conclusion. Although no difference persistsbetween the treatment groups for total-cholesterol, triglycerides,HDL-cholesterol, and LDL-cholesterol, the insulin/insulinanalogs seem to lower serum lipids most effectively, whichmay help prevent coronary events in T2DM patients.
