NCT03942744

Brief Summary

The main aim of this project is to evaluate, in patients with chronic kidney disease (CKD5D), the role of adhesion molecules in leukocyte adhesion and transendothelial migration involved in atherogenesis. This trial is a prospective randomized crossover study in CKD5D hemodialysis patients followed in the Nephrology Unit of the Reina Sofia University Hospital (Cordoba, Spain). The estimated inclusion period is two years, with a follow-up of 24 months. Patients will be randomized to high-flux hemodialysis versus online hemodiafiltration with high convective transport (above 21 liters); after 6 months in each dialysis modality they will be switched the other technique for another 6 months. Then, patients will be maintained during 4 weeks in conventional hemodialysis "wash out period", before being started in the other dialysis modality.

Outcome Measures

Primary Outcomes (1)

  • Effect of two different dialysis modalities (high flux vs online hemodiafiltration) on endothelial function markers: CD31,CD41,CD34; as measured by the percent of labeled cells obtained by flow cytometry.

    These parameters will assessed, in patients with chronic kidney disease (CKD5D), Blood will be drawn before the dialysis session following the scheduled of the protocol. The measuremets of CD31 CD41 CD34 will be performend by flow cytometry according to the standard methodology described in methods.

    6 months

Secondary Outcomes (3)

  • Effect of two different dialysis modalities ( high flux vs online hemodiafiltration) on hospitalization (hospital admission days/year).

    6 months

  • Effect of two different dialysis modalities ( high flux vs online hemodiafiltration) on Serum concentration of Fibroblast Growth Factor FGF23 (pg/ml) .

    6 months

  • Effect of two different dialysis modalities ( high flux vs online hemodiafiltration) on vascular injury related microRNAs (relative expression)
