Relationship between MPV and paraoxonase-1 activity, brachial artery diameter and IMT in patients with diabetes mellitus

Aims: Higher mean platelet volume (MPV) in diabetic patients has been considered as an emerging risk factor for diabetes related micro- and macrovascular complications. Human paraoxonase 1/arylesterase (PON1), which has antioxidant and antiatherogenic properties, is documented in high oxidative stress conditions like uncontrolled diabetes. The present study aimed to evaluate the relationship between mean platelet volume (MPV) and paraoxonase-1 (PON-1) activity, brachial artery diameter (BAd) and intima media thickness (BA-IMT), in diabetic patients with regard to obesity and diabetic complications.Methods: Two-hundred and one diabetic patients (mean age: 52.4 ± 13.4 years, 73.6% females) were grouped according to obesity and diabetic complications (microvascular and macrovascular). Data on demographics, anthropometrics, diabetic complications, MPV levels, BAd and BA-IMT, and serum paraoxonase and arylesterase activities were recorded. The correlation of MPV values to paraoxonase and arylesterase activitie...
