Italian cooperative hemoadsorption for relieving uremic symptoms

Official title: ICHARUS: Italian Cooperative HemoAdsorption Study for Relief of Uremic Symptoms. A Prospective Observational Cohort Study to Assess the Effectiveness and Safety of Hemoadsorption in Chronic Hemodialysis Patients With Refractory Uremic Symptoms: An Italian Real-World Registry.

Run by Azienda Ospedaliera Brotzu · NCT07522008 · Data updated 2026-11-12

This registry will follow adults on maintenance hemodialysis to see if adding hemoadsorption to their dialysis helps relieve persistent uremic symptoms.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with CKD stage 5D on stable maintenance hemodialysis for at least 3 months who have at least one moderate-to-severe uremic symptom and are planned for hemoadsorption per routine clinical care are ideal candidates.

Probably not a fit

Patients with recent acute illness or infection, planned transplantation during follow-up, very limited life expectancy, inability to complete questionnaires, or symptoms not related to protein-bound or middle-molecule toxins may be unlikely to benefit from HAHD in this registry.

What this trial studies

ICHARUS is a prospective, multicenter, observational registry collecting real-world data on hemodialysis combined with hemoadsorption (HAHD) in adults with end-stage kidney disease on maintenance dialysis. Patients are enrolled when their treating physician prescribes hemoadsorption as part of routine care for persistent moderate-to-severe uremic symptoms. The registry records indications, treatment patterns, changes in symptom scores and patient-reported outcomes, and safety events without altering standard clinical practice. Data will describe how HAHD is used across centers and how symptoms and adverse events evolve over time.

Why it matters

Potential benefit: If successful, HAHD could reduce stubborn uremic symptoms and improve quality of life for patients on maintenance hemodialysis.

How similar studies have gone: Small observational and mechanistic studies suggest hemoadsorption can enhance removal of protein-bound and middle-molecule toxins and may improve symptoms, but large randomized trials providing definitive evidence are limited.
