Ultrapure Water System for Hemodialysis Therapy
Recruitment status was Not yet recruiting
We wish to compare the effect of very clean water used for dialysis therapy (i.e ultrapure water) in comparison with the use of conventional water which are used in most dialysis units worldwide. To the best of our knowledge prospective data in that field is sparse.

In observational studies, the use of very pure dialysis solution has been suggested to reduce the plasma level of CRP, IL-6 ; to improve the response to anemia to erythropoietin therapy ; to promote better nutrition as evidenced by increase in plasma albumin value , estimated dry body weight, midarm muscle circumference and urea-nitrogen appearance rate; to reduce plasma level of β2-microglobulin and pentosidine ; to dely carpal tunnel syndrome ; to slow the loss of residual renal function; and to lower cardiovascular morbidity.The aim of this study is to prospectively evaluate the effect of dialysis performed with ultra-pure water (UPW)in comparison with dialysis with the use of conventional water system. Patients enrolled into this study will be evaluated at initial period of one month treated with conventional water system (-30 to 0 days). Then water system will be switched to ultra-pure water system with the use of filter added to the dialysis machine (Gambro). After switching to UPW system the patients will be followed for a period of one year (days 0-365). Primary end point will be change in CRP. Additional parameters: Blood pressure, adverse events during dialysis, hemoglobin levels and white-blood cell counts.
