[Effect of hemodialysis using cuprophan and polysulfone dialyzers on rosette tests, concentration of immunoglobulins and complement components in serum of patients with chronic renal failure].

In 15 patients with chronic renal failure, the effect was studied of haemodialysis using cuprophan and polysulfone dialyzers on rosette tests, and the concentrations of immunoglobulins and C3c and C4 complement components in peripheral blood. It was found that the per cent of E and EAC rosettes decreases within 30 minutes of the procedure, IgG, IgA and IgM levels increase after 120 minutes of the procedure, while the concentrations of C3c and C4 components are not changing significantly during haemodialysis using both types of the dialyzers. The authors found that the polysulfone membrane seemed not to be more biocompatible than the cuprophan one.
