Hemodiafiltration With Endogenous Reinfusion on Uremic Toxins Clearance of Maintenance Hemodialysis Patients
Study Details
Study Description
Brief Summary
1.1Primary Objective To evaluate the clearance rate of uremic toxin β2-microglobulin (β2-MG), indoxyl sulfate and λ-free light chain (λFLC) by HFR.
1.2Secondary Objectives 1.1.1 To evaluate the clearance of low molecular weight uremic toxin urea (spKt/V, URR).
1.1.2 To evaluate the clearance of other middle molecules and macromolecular uremic toxins, including α1-microglobulin (α1-MG), κ-free light chain (κFLC), homocysteine (Hcy), interleukin-6 (IL-6), p-cresol, YKL-40, complement factor D (CFD), leptin, hippuric acid, trimethylamine oxide (TMAO), asymmetric dimethylarginine (ADMA), tumor necrosis factor-α (TNF- α), myoglobin, fibroblast growth factor 23 (FGF23) and intact parathyroid hormone (iPTH).
1.1.3 To evaluate the clearance of serum albumin, branched chain amino acids and vitamins A, C, E.
1.1.4 To evaluate the comfort of HFR treatment for MHD patients.

Outcome Measures
Primary Outcome Measures
- β2-microglobulin (β2-MG), indoxyl sulfate and λ-free light chain (λFLC) [1 day]
The concentrations of β2-microglobulin (β2-MG), indoxyl sulfate and λ-free light chain (λFLC) were measured before and after HFR
Secondary Outcome Measures
- Single-compartment urea clearance index (spKt/V), Urea Reduction Ratio [1 day]
Calculate spKt/V and Urea Reduction Ratio.
- other middle molecules and macromolecular uremic including α1-MG, κFLC, Hcy, IL-6, p-cresol, YKL-40, CFD, leptin, hippuric acid, TMAO, ADMA, TNF-α, myoglobin, FGF23 and iPTH [1 day]
The concentrations of other middle molecules and macromolecular uremic were measured before and after HFR
- serum albumin, branched chain amino acids and vitamins A, C, E [1 day]
The concentrations of serum albumin, branched chain amino acids and vitamins A, C, E before and after HFR
- the comfort of HFR treatment [1 day]
The dialysis comfort score was used for evaluation
