Lipoprotein associated phospholipase A2 activity & its correlation with oxidized LDL & glycaemic status in early stages of type-2 diabetes mellitus

Lipoprotein associated phospholipase A 2 (Lp-PLA 2 ) is an important risk predictor of coronary artery disease (CAD). This study was aimed to evaluate Lp-PLA 2 activity and oxidized low density lipoprotein (oxLDL) in newly diagnosed patients of type 2 diabetes mellitus and to determine the correlation of Lp-PLA 2 activity with oxLDL and plasma glucose levels. Blood samples were collected in patients with newly diagnosed type 2 diabetes (n=40) before any treatment was started and healthy controls (n=40). These were processed for estimating plasma glucose: fasting and post prandial, ox LDL, and Lp-PLA2 activity. The parameters in the two groups were compared. Correlation between different parameters was calculated by Pearson correlation analysis in both groups. Lp-PLA 2 activity (24.48 ± 4.91 vs 18.63 ± 5.29 nmol/min/ml, P
