A Randomised, Open-Label, Cross Over Group, Single-Centre Controlled Study To Evaluate The Clinical Performance Of Medium Cut-Off Membrane Dialyser Compared With High Flux Dialyser Among Patients With Chronic Haemodialysis

This is an open label, cross-over group, single-centre randomised controlled trial comparing Medium Cut Off(MCO) Dialyser with High Flux Dialyser in patients with end-stage renal disease on chronic haemodialysis.

Patients who are initially on High Flux Dialyser will be randomised into either MCO Dialyser (modality A) or High Flux Dialyser (modality B) dialysate. The dialysate flow (QD) and blood flow (QB) remains unchanged throughout study period. After 12 treatments (4 weeks) a 4-weeks wash-out phase using High-flux dialyzers was performed to minimize carry-over-effects. After the 4-weeks washout phase, the modality is switched to the alternative one for 8 weeks.
