Effect of Kidney Replacement Therapy with Polymethylmethacrylate Membranes on Pruritus-related Quality of Life in Patients Receiving Maintenance Haemodialysis

This randomized controlled trial aims to evaluate the effect of polymethylmethacrylate dialysis membranes use on the intensity of pruritus in patients with CKD stage 5D receiving maintenance hemodialysis. The main question it aims to answer is: Does the use of polymethylmethacrylate (PMMA) membranes reduce the intensity of pruritus in dialysis patients? Researchers will compare PMMA membranes to standard polysulfone-based membranes to see if PMMA works to reduce moderate-to-severe pruritis and pruritis-related quality of life. Participants will: * receive maintenance hemodialysis with PMMA or polysulfone membranes for 2 months; * fill in questionnaires about intensity of pruritis and its impact on daily life.
