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.

Summary
Brief summary
Increased ADMA levels in patients undergoing HD, as compared to PD, may be caused by higher oxidative stress and lower residual renal function in HD. Other
factors, such as diabetes and statin therapy, may also be at play. The decrease in ADMA at the end of HD and HDF
is comparable. Switching from HD to HDF decreases in 8 weeks the predialysis levels of homocysteine without affecting ADMA.
