The Effect of Different Dosages of Solute Clearance on Outcome in Twice Weekly Hemodialysis Patients
Study Details
Study Description
Brief Summary
Adequacy of solute clearance makes a profound impact on clinical outcome in maintenance hemodialysis patients. Thus far, guidelines on the target of solute clearance (Kt/V or URR) are based on patients with three dialysis sessions per week. However, quite a few patients have their dialysis sessions twice per week in China. The dialysis target of solute clearance in this population remains to be elucidated. The aim of this study was to explore the optimum target solute clearance (Kt/V or URR) in maintenance hemodialysis patients with two dialysis sessions per week. Two groups of hemodialysis patients with different Kt/V (1.2 ≤ Kt/V < 1.7 versus Kt/V ≥ 1.7) will be followed until 96 weeks in this prospective, randomized, multi-center, interventional study.

Detailed Description
This is a prospective, randomized, multi-center intervention study. 400 maintenance hemodialysis patients with twice dialysis sessions per week will be enrolled into the study. All the patients have their baseline Kt/V between 1.2 and 1.7 (1.2 ≤ Kt/V < 1.7). After treatment intervention, the patients will be randomized to two groups according to their different Kt/V (1.2 ≤ Kt/V < 1.7 vs. Kt/V ≥ 1.7), then the patients will be regularly followed up at baseline, 12 weeks, 24 weeks, 48 weeks, 72 weeks and 96 weeks. Clinical outcomes such as mortality, complications and life quality between the two groups will be investigated.
