简要总结
The study's hypothesis is that HD with large pore dialyzers remove to the dialysate iron which is bound to potentially dialyzable ligands, after it's release from intravenous iron compound administered during hemodialysis.
详细描述
Most hemodialysis(HD) patients receive during HD intravenous iron compounds, which are composed of an iron core and a sugar polymer shell.
A small percentage of iron from the iron compound is released to the plasma, and may be associated with increased oxidative stress and protein oxidation. The study's hypothesis is that HD with large pore dialyzers may remove to the dialysate iron which is bound to potentially dialyzable ligands, after it's release from intravenous iron compound administered during hemodialysis.
Ligand-bound iron removal is also hypothesized to be affected by dialysate calcium and bicarbonate concentrations, which may affect iron-ligand binding.
