Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eight weeks of hemodialysis (HD, low-flux polysulfone membrane) versus eight weeks of on-line predilution hemodiafiltration (HDF, high-flux polysulfone membrane, susbstitution volume 200 mL/min)), duration of both HD and HDF was 4.5 hrs/session 3 times a week. Crossover study, 1 week break in between.
Intervention code [1] 255807 0
Treatment: Devices
Comparator / control treatment
Controls were volunteers without renal disease and without treatment. We studied baseline values of controls, 20 HD patients and 19 peritoenal dialysis patients. Then, randomly selected 16 HD patients were randomized to crossover study, 8 started with HD, 8 with HDF.
Control group
Active

Outcomes
Primary outcome [1] 240795 0
Change in plasma levels of asymmetric dimethylarginine (ADMA), advanced glycation end-products and homocystein after a period of 8 weeks of hemodiafiltration or hemodialysis. This primary outcome is being done in patients with end stage renal disease.
