ABSTRACT
BACKGROUND:
The number of circulating endothelial progenitor cells (EPCs) decreases on account of chronic kidney disease (CKD).METHODS:
Twenty patients were enrolled in this prospective and randomised study in two parallel arms conventional haemodialysis versus online haemodiafiltration. EPCs number and T-cell activation were analysed at baseline and monthly during a 4-month period of follow-up.RESULTS:
CD38(bright) and HLA-DR+ expression among CD8 memory T cells were negatively associated with both CD34+ (r = -0.70, p = 0.0006) and CD34+ CD133+ (r = -0.62, p = 0.004) cell numbers. Conversely, a positive correlation was observed between CD34+ and CD34+ CD133+ cells with transferrin (r = 0.75, p = 0.0001 and r = 0.47, p = 0.04, respectively), and CD34+ CD133+ cells with transthyretin (r = 0.51, p = 0.02). No significant association was observed between dialysis modality and the evolution of the EPC number.CONCLUSIONS:
Chronic T-cell activation may be a component of the malnutrition inflammation complex syndrome that adversely influences EPC mobilization in CKD patients.
