[Inflammation markers and endothelial disfunction in children with type 1 diabetes].
A subclinical inflammation state was detected in the early step of diabetes, which increases the serum levels of cytokines that induce acute-phase protein synthesis as C-reactive protein (PCR) and fibrinogen (Fg), stimulating the endothelial disfunction of adhesion molecules. Thirty patients (15 boys, 15 girls) with type 1 diabetes (DT1), without vascular complications, were studied. Their mean age and duration of diabetes were 11.8 +/- 2.1 and 3.9 +/- 3.2 years, respectively. The laboratory parameters evaluated were: blood leukocytes count, globular sedimentation velocity, fasting glycemia, glycosylated hemoglobin (HbA1c), high sensitivity PCR (uPCR), plasma soluble E-selectin (sE-S), sVCAM-1 and microalbuminuria. Increased levels of uPCR, sE-S and VCAM-1 were found, compared with the control group control [0.60 (0.30-1.25) vs. 0.20 (0.20-0.65) mg/l, p = 0.013], [108 (60-150) vs. 68 (56-82) ng/ml, p = 0.0031] y [750 (708-826) vs. 721 (674-751) ng/ml, p = 0.039] respectively. When diabetic patients were grouped according to duration of disease (3 and > de 3 years), uPCR values were higher in the second group. uPCR levels were better correlated with sE-S (r = 0.44, p = 0.03) and VCAM-1 (r = 0.49, p = 0.02). These results suggest the presence of pro-inflammatory and endothelial activation states, which are strongly associated with DT1.
