Although hemodialysis (HD) has improved the life expectancy of patients with end-stage renal disease (ESRD), uremic patients continue to experience high morbidity and mortality. Two of the most important risk factors for morbidity and mortality are protein-energy malnutrition (PEM) and inflammation. The causes for PEM in ESRD are numerous. The use of materials for dialysis, especially of the dialyzer membrane, is reported as one of the recognized causes for chronic inflammation in hemodialysis. We performed a 6-month prospective study examining the influence of on-line predilution hemodiafiltration on the inflammatory and nutritional status in a population of male hemodialysis patients using ultrapure dialysis fluid and polyamide dialyzers. We evaluated serum C-reactive protein, albumin, and transferrin and some nutritional parameters such as body mass index (BMI), phase angle (φ), fatty mass (FM), and free fatty mass (FFM) using bioelectrical impedance (BIA). Results showed significant amelioration of BMI and the re-equilibrium of the acute phase protein after on-line predilution hemodiafiltration. These results support the hypothesis that on-line predilution hemodiafiltration, as convective extracorporeal treatment, may be used to treat malnourished hemodialysis patients and to prevent malnutrition in the ESRD patient at risk for malnutrition.
