title: [hsCRP protein in children and adolescents with diabetes type 1].
abstract: BACKGROUND
  HsCRP protein is known as a novel marker of low grade inflammatory state, which characterises an atherosclerotic process in its early stages. Contrary to a large amount of data on inflammatory markers in diabetes type 2 and metabolic syndrome in adults, little is known so far about the inflammatory process in diabetes type 1, especially in children. The aim of the study was to estimate the level of hsCRP protein in children and adolescents with diabetes type 1 depending on coexisting additional risk factors for atherosclerosis and microvascular complications.
  
  
  METHODS
  127 children and adolescents with diabetes duration 6.7+/-3.3 years, aged 14.9+/-3.1, were studied. The control group consisted of 52 healthy children aged 14.9+/-2.8 years, matched acc. to gender. HsCRP level was assessed with use of immunoturbidymetric, latex augmented method (Tina-quant CRP (Latex) HS, Roche).
  
  
  RESULTS
  HsCRP in the whole study group was nearly significantly higher compared to control group: 0.17+/-0.2 vs. 0.078+/-0.1 mg/dl, p=0.072. In diabetic hypertensive children (n=38) we found significantly higher levels of hsCRP compared to controls (0.27+/-0.3 vs. 0.07 mg/dl, p=0.008) and compared to diabetic normotensive children (0.13+/-0.22 mg/dl; p=0.024). Diabetic obese patients (n=23) had significantly higer hsCRP compared to controls (0.24+/-0.3 vs. 0.07+/-0.1 mg/dl, p=0.04). In 14 studied diabetic children we found coexisting hypertension and obesity, and we found further increase in hsCRP level - 0.28+/-0.3 mg/dl. In diabetic children with microangiopathy hsCRP level was 0.22+/-0.2 mg/dl, and it was insignificantly higher compared to controls and to diabetic children without complications. Correlation analysis showed interrelations between hsCRP and systolic blood pressure (r=0.2; p=0.04) and HbA1c (r=0.25; p=0.015). In stepwise regression analysis hsCRP was related to systolic blood pressure, HbA1c and the triglycerides level (R=0.37; p=0.003).
  
  
  CONCLUSIONS
  In children and adolescents with diabetes type 1 we proved significantly higher levels of hsCRP in case of a coexistence of hypertension and/or obesity. Elevated hsCRP in children with diabetes type 1 and hypertension and/or obesity reflects low grade inflammatory state in the course of metabolic syndrome.
