In children and adolescents with type 1 diabetes (T1D), clinical manifestations of vascular complications are uncommon; however, endothelial disturbance and a pro-inflammatory state can emerge early. The objectives of this work were: I) to determine plasma levels of proinflammatory molecules in a  T1D pediatric population with no clinical evidence of vascular complications; II) to correlate these parameters with each other, and with glycemic control degree and disease duration. Forty-two patients with T1D (21 M/21W), aged 10 and 13 years and an evolution time not more than 6 years were compared with a control group. The biochemical parameters evaluated were: WBC, sE-S and VCAM-1, MPO, TNF-á, hsCRP and plasma Fg. Glycemic control was performed by determining fasting glucose and HbA1c. Data were expressed as the median and interquartile range. Increased levels of sE-S [108 (69-150) vs. 68 (52-86) ng/mL, p=0.003], VCAM-1 [785 (732-835) vs. 712 (658-758) ng/mL, p=0.04], hsCRP [1.00 (0.67-1.70) vs. 0.20 (0.18- 0.87) mg/L, p=0.01] were found in diabetic patients compared with the control group. No differences in the studied molecules were observed when diabetic patients were grouped according to glycemic control degree and evolution of the disease. hsCRP correlated with fasting glucose, HbA1c, sE-S and VCAM-1. High hsCRP, sE-S and VCAM-1 levels suggest a proinflammatory state associated with endothelial activation in children and adolescents with T1D, potentiating the risk of vascular disease.
