Objectives
Narrative objectives1
During a HD session, bioincompatibility, in which adverse effects are induced in the blood after contact with components of the HD system, is important. Consequently, the purity of the dialysate and the permeability of the membrane to dialysate contaminants might contribute in part to the acute and long-term complications that afflict HD patients. Conventional dialysate (CD) has been shown to contain microbial components. Increasing dialysate purity effectively reduces chronic inflammation and oxidative stress. However, it remains unclear how dialysate purity affect white blood cells (WBC) activation. In the present study, impact of purified dialysate on activation of WBC (neutrophils and monocytes) will be analyzed.

Assessment
Primary outcomes
Comparison of expression levels of white blood cells (neutrophils and monocytes) surface receptors (TR2, TR4, CD11b, CD14, CD16, CD18), inflammatory factors (cytokone, myeloperoxidase) releasing from those cells between CD and ultrapuredialysate.
Key secondary outcomes
Comparison of serum protein, nutritional state
