title: Association of E-selectin with hematological, hormonal levels and plasma proteins in children with end stage renal disease.
abstract: BACKGROUND
  Hypercoagulable state is a common serious problem in patients with end-stage renal disease (ESRD). ESRD patients are in a condition of chronic inflammation. An increased level of E-selectin, "a key adhesion molecule that regulates leukocyte bindings to endothelium at damaged sites," accompanies the higher risk of inflammation in ESRD patients. We aimed to investigate the possible correlation among E-selectin as an adhesion molecule, coagulation factors, and inflammatory factors in children with ESRD.
  
  
  METHODS
  Thirty-five child patients with ESRD who had been on regular dialysis treatment were registered in our study. Nighteen sex- and age-matched healthy volunteers were used as the control group. Laboratory tests were requested for the evaluation of hematological and biochemical parameters, and parathyroid hormone (PTH), and for coagulation state; fibrinogen, protein C, and protein S were measured. The enzyme-linked immunosorbent assay (ELISA) (Biomerica, CA, and IDS, UK). for serum E-selectin assay was provided by R and D Systems (Abingdon, UK).
  
  
  RESULTS
  Hemoglubolin (Hb), blood urea nitrogen (BUN), creatinine, calcium, PTH, triglyceride (TG) concentrations in serum as well as E-selectin showed significant difference between the two study groups, as indeed was expected. Serum E-selectin was significantly higher (P value = 0.033) in dialysis patients than in healthy subjects. E-selectin was positively correlated only with phosphorus in ESRD children (r = 0.398, P = 0.018). No association was found for other parameters.
  
  
  CONCLUSIONS
  Although in our study circulating E-selectin concentration "as an inflammatory maker" is independently positively associated with limited blood markers, for better evaluation, well-designed cohort studies should be examined in ESRD children.
