About this study

Official title: Reduction of Inflammation Reaction to Extracorporeal Circulation in Cardiac Surgery by Interleukin Dialysis

The aim of this study is to prove that using a CytoSorb(TM) filter in the cardiopulmonary circuit attenuates the inflammatory response to extracorporeal circulation in patients undergoing cardiac surgery. The hypothesis is that removing cytokines from patients' blood by the CytoSorb device significantly improves circulation and outcome in patients undergoing on-pump cardiac surgery.

Read the detailed description

Cardiac surgery with cardiopulmonary bypass (CPB) induces an inflammatory response due to contact of patients' blood with foreign surfaces like tubes or the oxygenator, ischemic-reperfusion injury and surgical trauma. Inflammation is modulated by cytokines, especially, interleukins. The extent of cytokine release is further related to the duration of bypass and the amount of operating field suction. This results in a systemic inflammatory response syndrome (SIRS) with the risk of multiple organ dysfunction (MOD). Also in patients treated with extracorporeal membrane oxygenation (ECMO) an activation of the inflammation system is seen and accompanied with an increase of cytokine levels. The cytokine concentration correlates with the severity of the immune reaction and can be a predictor of the outcome of the patient. As severe SIRS and MOD significantly increase mortality, the attenuation of the inflammatory response is supposed to reduce morbidity and mortality after cardiac surgery.

For adult cardiac surgery and patients who are treated with an extracorporal assist device, a tool for cytokine elimination and attenuation of the inflammatory response seems to be beneficial.

In our study we are going to investigate if the use of the CytoSorb device can improve the outcome of patients undergoing elective coronar artery bypass and heart valve surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CytoSorb deviceDevice

    Also called polymer beads adsorbent

    In 20 patients the CytoSorb device will be installed into the extra corporeal circuit. A blood flow of 400ml/min is provided by an roller pump of the heart lung machine in a parallel stream to the main circulation.

What is being measured

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

  1. Change of levels of cytokines during procedure compared to baseline

    parameters to be measured are: interleukin (IL) 1, interleukin 6, interleukin 8, interleukin 10, tumor necrosis factor-alpha

    Measured: 1) 5 minutes before bypass 2) 2 hours after begin of bypass, 3) at the end of bypass, approximately 3 hours after begin of bypass, 4) 6 hours after bypass 5) 24 hours after bypass

Secondary outcomes (3)
  1. Change of hemodynamic parameters during procedure compared to baseline

    Hemodynamic and respiratory parameters such as mean arterial pressure, heart rate and peripheral oxygen saturation are recorded. In addition thermodilution parameters (stroke volume variability, global end diastole volume, extravascular lung water index, cardiac index, systemic vascular resistance) are measured. Volume and catecholamine therapies are managed by an algorithm based on thermodilution parameters.

    Measured: 1) 5 kinutes before bypass 2) 2 hours after begin of bypass, 3) at the end of bypass, approximately 3 hours after begin of bypass, 4) 6 hours after bypass 5) 24 hours after bypass

  2. Thromboelastometry

    At the end of extracorporeal circulation a rotation thromboelastometry analysis is performed and the clotting time (CT), the clot formation time (CFT), the maximum clot firmness (MCF) in In- and Ex-Tem and the MCF in Fib-Tem are measured. Based on an institutional algorithm the coagulation therapy is performed according to the results of the thromboelastometry.

    Measured: at the end of bypass, approximately 3 hours after begin of surgery

  3. Change of cognitive and emotional state in comparison to condition before surgery

    To evaluate, if the use of the cytokine-filter has any influence on cognitive function or the emotional state, the patients perform the mini-mental state examination and answer questions of the Geriatric Depression Scale questionaire. Results before and 24 hours after end of bypass are recorded.

    Measured: 1)one day before surgery 2) 24 hours after bypass

Questions about this trial

What is this clinical trial studying?

A study testing CytoSorb device in people with Coronary Artery Disease and Heart Valve Diseases, run by Universitätsklinikum Hamburg-Eppendorf at 1 site in Germany.

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 2 inclusion and 6 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: finished, as of the sponsor's last update on 29 Aug 2017. 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 Germany. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change of levels of cytokines during procedure compared to baseline (time frame: 1) 5 minutes before bypass 2) 2 hours after begin of bypass, 3) at the end of bypass, approximately 3 hours after begin of bypass, 4) 6 hours after bypass 5) 24 hours after bypass). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Aug 2017.
