About this study

Official title: Comparison of Citrate and Heparin Anticoagulation During Hemodialysis With Medium Cut-off Polyarylethersulphone- Polyvinylpirrolidone (Theranova) Membrane

The purpose of the study is to compare the efficiency and biocompatibility of citrate and heparin anticoagulation during hemodialysis with medium cut-off polyarylethersulphone-polyvinylpirrolidone membrane (Theranova®).

Read the detailed description

The purpose of the study is to compare the efficiency and biocompatibility of citrate and heparin anticoagulation during hemodialysis (HD) with PES-PVP membrane. The research will be performed as a prospective clinical trial and will include 35 patients. Every patient will have 2 HD procedures with PES-PVP membrane in a randomized order: 1 with unfractionated heparin (UFH) and 1 with 8% trisodium citrate. We will compare the efficiency of both types of anticoagulation by measuring overall and instantaneous clearances of small, middle and protein-bound molecules (urea, creatinine, phosphate, β2-microglobulin, p-cresol). Biocompatibility will be evaluated by measuring activation of: complement (serum concentration of C3a and C5a), leukocytes (serum concentration of myeloperoxidase) and thrombocytes (serum concentration of PF4). We will also monitor complete blood count for occurrence of leukopenia and thrombocytopenia. After the HD electron microscopy of the membrane will be done in the proportion of included patients to evaluate adsorption of cells and formation of blood clots on the membrane.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clearance of beta-2 microglobulin

    Overall and instantaneous clearance of beta-2 microglobulin.

    Measured: At the end of each hemodialysis procedure.

  2. Clearance of phosphate

    Overall and instantaneous clearance of phosphate.

    Measured: At the end of each hemodialysis procedure.

  3. Serum concentration of C3a, C5a, myeloperoxidase and PF-4

    Blood for the laboratory measurements will be taken from the arterial line.

    Measured: At the start, after 15 minutes and at the end of each hemodialysis procedure.

Secondary outcomes (5)
  1. Clearance of urea

    Overall and instantaneous clearance of urea.

    Measured: At the end of each hemodialysis procedure.

  2. Clearance of creatinine

    Overall and instantaneous clearance of creatinine.

    Measured: At the end of each hemodialysis procedure.

  3. Clearance of p-cresol

    Overall and instantaneous clearance of p-cresol.

    Measured: At the end of each hemodialysis procedure.

  4. White blood cell count

    Blood for the laboratory measurements will be taken from the arterial line.

    Measured: At the start, after 15 minutes and at the end of each hemodialysis procedure.

  5. Blood platelet count

    Blood for the laboratory measurements will be taken from the arterial line.

    Measured: At the start, after 15 minutes and at the end of each hemodialysis procedure.

Questions about this trial

What is this clinical trial studying?

A study testing unfractionated heparin and 8% trisodium citrate in people with End Stage Renal Disease and Haemodialysis, run by Marija Malgaj Vrečko at 1 site in Slovenia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 7 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clearance of beta-2 microglobulin (time frame: At the end of each hemodialysis procedure.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04139525, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jun 2022.
