Effect of PMMA (BK-F) membrane on the elimination of sCD40 from serum of haemodialysed patients. (a) Longitudinal study of sCD40 levels. Soluble CD40 concentrations were monthly determined by ELISA in the serum of three patients who were dialysed on classical membranes before to be dialysed on BK-F membrane. Blood samples were taken after the dialytic session. (b) Per dialytic elimination of seric sCD40 during haemodialysis on BK-F membrane. Soluble CD40 was measured in the serum taken weekly just before and after one dialysis session on BK-F.
