PMMA vs Polysulfone in SARS-CoV-2 Infection Hemodialysis Patients

Not Applicable
Conditions
SARS-CoV-2 Infection
Interventions
Device: PS membrane versus PMMA membrane,
Registration Number
NCT05040737
Lead Sponsor
Fundación para la Investigación del Hospital Clínico de Valencia
Brief Summary

Controlled, prospective, open-label trial with a total duration of 2 weeks to assess the clearance of inflammatory interleukins by different membranes in haemodialysis patients with COVID-19.

Detailed Description

Controlled, prospective, open-label trial with a total duration of 2 weeks to assess the clearance of inflammatory interleukins by different membranes in haemodialysis patients with COVID-19.

Patients will be dialysed according to the usual dialysis schedule of three weekly sessions. The study has a duration of 8 days in order to include 4 haemodialysis sessions. The first and third haemodialysis sessions will be dialysed with PS membrane and the second and fourth sessions with PMMA membrane, both dialysers with a surface area of 1.8 m2.
