The Effect of Hemodiafiltration on Inflammatory Biomarkers in Comparison to High Flux Dialyzers in Prevalent Hemodialysis Patients

Abstract

Inflammation in patients with ESRD undergoing HD is an increasing concern for physicians and has been related to increase the rates of morbidity and mortality. Interestingly, patients with ESRD in conventional HD have frequent infections and a suboptimal response to vaccines; this is probably related to an immune inflammatory disorder associated either with uremia and /or nutritional status. In addition to CRP, which seems to be the most important marker for the identification and control of inflammation in clinical practice, many other markers are also available for the evaluation of inflammatory state. Decreased renal clearance clearly accounts for higher levels of circulating cytokines, although increased production has also been described. Hemodiafiltration has been shown to improve cardio-protection and the immunologic system and reduces infection and mortality compared with conventional HD.
