Summary

This study looks at whether adding a blood-filtering step called hemoadsorption to regular dialysis can help people with kidney failure who still have bothersome symptoms like itching, tiredness, and trouble sleeping. Researchers will follow 120 adults for 6 months, tracking how their symptoms and quality of life change. It is an observational registry, meaning doctors use the filter as part of normal care, and the study just watches what happens.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
hemoadsorption (a blood-filtering device added to standard dialysis)
What this could lead to
If successful, this could show that adding hemoadsorption to dialysis helps reduce stubborn symptoms like itching and fatigue, improving quality of life for kidney patients.
What could go wrong
This is an observational registry, not a controlled trial, so results may be influenced by other factors. It is small (120 people) and early, so it cannot prove the treatment works definitively.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of adult patients with end-stage kidney disease (CKD stage 5D) receiving maintenance hemodialysis in participating dialysis centers. Eligible participants are individuals with a stable dialysis regimen who report at least one clinically relevant uremic symptom at baseline, as assessed by the Dialysis Symptom Index. Patients are enrolled during routine clinical care and followed prospectively after initiation of hemodialysis combined with hemoadsorption, in accordance with local standard practice.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients (≥18 years) with end-stage kidney disease (CKD stage 5D) on maintenance hemodialysis. * Stable hemodialysis treatment for at least 3 months prior to enrollment. * Presence of at least one moderate-to-severe uremic symptom, as identified by the Dialysis Symptom Index at screening. * Planned treatment with hemodialysis combined with hemoadsorption according to local clinical practice. * Ability to provide written informed consent. Exclusion Criteria: * Acute illness, active infection, or hospitalization within 4 weeks prior to enrollment. * Planned kidney transplantation within the study follow-up period. * Life expectancy less than 6 months due to non-renal comorbid conditions. * Inability to complete patient-reported outcome questionnaires. * Participation in another interventional clinical study that could interfere with study outcomes.
