End‐stage renal disease (ESRD) patients are known to suffer from chronic inflammation as the result of an ongoing subacute cytokine induction, which may contribute considerably to dialysis‐related, long‐term morbidity and mortality. Preparation of infusate from cytokine‐inducing dialysis fluid and its administration in large quantities as well as the use of high‐flux membranes bear the risk of aggravating the chronic inflammatory response among online hemodiafiltration (online HDF) patients. In order to assess the inflammatory risk associated with online HDF, we compared the cytokine induction profile of ESRD patients receiving either online HDF or low‐flux hemodialysis (low‐flux HD). Specifically, we measured spontaneous and lipopolysaccharide (LPS)‐stimulated tumor necrosis factor α (TNFα) and interleukin‐1 receptor antagonist (IL‐1Ra) release during ex vivo incubation of whole blood. Ultrapure dialysis fluid and polysulfone membranes were used for both treatment modalities. LPS‐stimulated release of TNFα and IL‐1Ra was elevated for both online HDF and low‐flux HD patients compared to healthy individuals (TNFα: 2,336 ± 346 and 2,192 ± 398 versus 1,218 ± 224 pg/10 6 white blood cells [WBC]; IL‐1Ra: 2,410 ± 284 and 2,326 ± 186 versus 1,678 ± 219 pg/10 6 WBC). Likewise, spontaneous production of TNFα, but not IL‐1Ra, was higher in online HDF and low‐flux HD patients than in normal controls (37 ± 32 and 22 ± 19 versus 0.8 ± 0.3 pg TNFα/10 6 WBC). There was no difference in spontaneous and LPS‐stimulated cytokine release between both dialysis groups. In addition, intradialytic cytokine induction was not significant for either treatment modality as spontaneous and LPS‐stimulated cytokine release were not increased postdialysis. These findings indicate that online HDF does not contribute to chronic leukocyte activation and, consequently, does not place ESRD patients at greater risk with respect to inflammatory morbidity and mortality.
