Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with chronic kidney disease stage 5D who have been on maintenance hemodialysis for at least three months and experience moderate-to-severe pruritus.

Probably not a fit

Patients with active skin diseases or other conditions causing pruritus unrelated to kidney disease may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effectiveness of polymethylmethacrylate (PMMA) membranes in reducing pruritus in patients with chronic kidney disease stage 5D undergoing maintenance hemodialysis. Participants will be randomly assigned to receive either PMMA or standard polysulfone membranes for a duration of two months. Throughout the study, patients will complete questionnaires to assess the intensity of their itching and its impact on their quality of life. The goal is to determine if PMMA membranes can significantly alleviate moderate-to-severe pruritus compared to traditional membranes.

Why it matters

Potential benefit: If successful, this study could lead to improved quality of life for dialysis patients suffering from severe itching.

How similar studies have gone: While the use of PMMA membranes is a novel approach, similar studies have shown promise in addressing pruritus in dialysis patients.
