title: Effect of Different Dialysis Methods on Cellular Immunity Function of Maintenance Haemodialysis Patients.
abstract: The study of the effect of different dialysis methods on cellular immune function of maintenance haemodialysis (MHD) patients should provide theoretical support for deciding on the best method of blood purification that effectively improves cellular immune function of haemodialysis patients.
  
  
  
  Sixty MHD patients were randomly divided into three groups that respectively received treatment of haemodialysis (HD), high flux haemodialysis (HFHD) and haemodiafiltration (HDF). Peripheral blood T lymphocyte subsets [CD4+, CD8+, CD25+ (mIL-2R) and CD4+/CD8+ ratio] and serum interleukin (IL)-2 and soluble IL-2 receptor (sIL-2R) levels were detected before dialysis and 4, 24 and 48 hours after dialysis in all cases.
  
  
  
  Compared with the HD group, CD4+ and CD25+ cells, CD4+/CD8+ ratio and IL-2 level increased but sIL-2R level decreased in the HFHD and HDF groups at four hours without statistical significance (p> 0.05) and at 24 and 48 hours after dialysis with statistical significance (p< 0.05), while CD8+ cells had no change after dialysis (p> 0.05). Compared with the HFHD group, CD4+ and CD25+ cells, CD4+/CD8+ ratio, and IL-2 level increased but sIL-2R level decreased in the HDF group at four and 24 hours without statistical significance (p> 0.05) and at 48 hours after dialysis with statistical significance (p< 0.05), while CD8+ cells had no change after dialysis (p> 0.05).
  
  
  
  The results indicate that HD can briefly improve the cellular immune function of MHD patients, while MHD and HFHD can improve it continuously, with HDF having the best effect.
