Abstract: (8703 Views)
Background: Type 2 diabetic patients have 2 or 4 fold risk of coronary heart diseases. According to researches, all types of dyslipidemia independently have atherogenic properties so it seems small dense LDL has the most effects in this case. To investigate whether glycemic control, which is assessed by concurrent HbAlc, has any favorable impact on LDL size we determined the relation between LDL size and HbAlc in diabetics.
Methods: In this study, LDL size was determined by non-denaturing polyacrylamide gel electrophoresis in 81 type 2 diabetics 50 to 70 aged. BMI was calculated in all participants as weight (Kg) divided by height (m2). TG and HDL-C were measured using enzymatic kits. HbAlc was determined using immunoturbidometric method.
Results: Based on results obtained LDL size in diabetics was significantly correlated with TG (r=-0.281, P<0.05), sex (r=-0.276, P<0.05), HbAlc (r=-0.232, P<0.05) and HDL-C (r=0.215, P<0.01). In linear regression analysis TG (standardized =-0.192 p<0.054), HDL-C (standardized =0.214 p<0.05) and female sex (standardized =0.196 p<0.056) were the independent determinants of LDL size (although they showed borderline significance). HbAlc showed high co linearity with HDL-C and was excluded from the model.
Conclusion: HbAlc is inversely correlated with LDL size in diabetics. However it is not an independent predictor of LDL size. It is likely that decrease in HDL-C levels due to poor glycemic control results in decrease in LDL size.
