ABSTRACT
OBJECTIVE: To examine whether oxidative stress parameters were correlated with adhesion molecules derived from endothelial/platelet activation in a group of juveniles with type 1 diabetes mellitus (T1DM). SUBJECTS AND METHODS: Indicative parameters of patient oxidant/antioxidant capacity were measured and associated with P-selectin and tetranectin (TN), markers of endothelial/platelet activation, in the plasma of 45 diabetic children and adolescents and 20 healthy age-matched subjects (HS). RESULTS: Significantly, higher nitrate/nitrite (NOx) and lipid hydroperoxide (LPO) levels (p=0.049 and p=0.0011, respectively), lower glutathione peroxidase activity (GPx; p=0.038), and elevated TN and P-selectin plasma levels (p=0.0046 and p=0.042, respectively) were found in T1DM children compared with HS. Well-controlled T1DM children (HbA1c
