It has been recently proposed that haemodialysis membrane choice may influence the
maintenance of residual renal function. The aim of the present study was to prospectively
analyse the effect of membrane choice on the outcome of renal function in patients entering
a chronic haemodialysis programme. Twenty-two patients from four hospitals have been
randomly assigned to be dialysed with either polysulphone (PSF)/polyacrylonitrile
(PAN)(group A; n= 9), or cuprophane membranes (group B; n= 13). Basal and monthly …

… We think that this deduction is not justified, considering the design of their study.
Progression of chronic … Preliminary results of our ongoing prospective randomized study
show that cellulosic dialysis membranes lead to an accelerated progression of renal failure.
After 9 months of … First, we believe that the evidence showing a different rate of decline of
residual renal function between glomerular or tubulointerstitial disease is less than impressive
once a terminal loss of renal function is reached. Therefore it is rather difficult that this point …
