Enhanced Lipid Peroxidation and Platelet Activation in the Early Phase of Type 1 Diabetes Mellitus

Background— To investigate early events possibly related to the development of diabetic angiopathy, we examined whether 8-iso-prostaglandin F 2α (8-iso-PGF 2α ) formation, a marker of in vivo oxidant stress, is altered in different stages of type 1 diabetes (T1DM) and whether it correlates with the rate of thromboxane (TX) A 2 biosynthesis, a marker of in vivo platelet activation. We also investigated the relationship between inflammatory markers and F 2 -isoprostane formation in this setting. Methods and Results— A cross-sectional study was performed in 23 insulin-treated patients aged <18 years with new-onset T1DM (≤6 weeks, group A), matched for age and gender with 23 patients with s…
