Influence of Cytosorb on Amount of Catecholamine and Mortality in Sepsis

February 2, 2021 updated by: Medical University Innsbruck

Retrospective Analysis of the Influence of Cytosorb on Catecholamine Reduction and Mortality in SIRS and Sepsis

The aim of this retrospective study was to identify if the enrolled patient might have had a profit of Cytosorb therapy. Primarily the decline in catecholamine therapy under Cytosorb therapy will be investigated. Secondarily the outcome of surviving patients will be evaluated and compared to expected mortality due to sequential organ failure assessment (SOFA). Thirdly the patients deceased under this therapy were compared to the surviving patients.

Detailed Description

Severe septic Shock has a high mortality ranging from 30-55% and might lead up to 100% mortality under cardiovascular failure and vasoplegia in the initial phase of severe septic shock . Mostly caused by bacteremia, it can also be triggered by viral or fungal infections. Due to vasodilatation caused by toxins the circulatory system of the patient fails. This will lead to further malfunctions of the patient organs (e.g. renal malfunction, vasodilation, myocardial pump failure and DIG) and will cause multiorgan system failure.

Nowadays there is a symptomatic approach to treat septic shock. Except of giving antibiotics less can be done to improve the patient's condition. Treatment with fluids, catecholamines, mechanical ventilation, renal replacement therapies are all regimen to bridge failed organ systems until normal organ function is restored and starts to improve. It is known that the cytokines and toxins, which are liberated by the breakdown of bacterial cells, maintain the inflammatory response of the body. This process might be overshooting and if not disrupted, the patient will die.

A new approach is to bind this cytokines and toxins in an unspecific physical process to tiny plastic beads, which are arranged in the CytoSorb System as they correlate with severity of mortality in sepsis . This polymer beads allow adsorption and binding of molecules from 5-60 kDa (kilodalton) range. Therefore, Cytokines as IL(interleukin)-1, -6, -8 and -10 can be effectively removed. CytoSorb has to get in contact with patient blood. To use this option of treatment CytoSorb is implemented in a renal replacement system, a heart lung machine, ECMO (extracorporeal membrane oxygenator) or any other extracorporeal pump driven system. By extracorporeal blood purification in septic shock the main goal is to eliminate inflammatory mediators and bacterial toxins. This might attenuate the excessive inflammatory response and could lead to hemodynamic stabilization .

The aim of this retrospective study was to identify if the enrolled patient might have had a profit of Cytosorb therapy. Primarily the decline in catecholamine therapy under Cytosorb therapy will be investigated. Secondarily the outcome of surviving patients will be evaluated and compared to expected mortality due to sequential organ failure assessment (SOFA). Thirdly the patients deceased under this therapy were compared to the surviving patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Due to this relatively new treatment concept there is less data at the moment available. 50 patients treated with CytoSorb, if available, in suspicion of severe septic shock will be examined to collect data on outcome. These patients will be compared to 50 patients not treated with CytoSorb. Overall about 100 patients will be analysed.

Description

Inclusion Criteria:

  • No CytoSorb therapy in patient suspected for sepsis or SIRS (systemic inflammatory response syndrome)
  • CytoSorb therapy in patient suspected for sepsis or SIRS

Exclusion Criteria:

  • no signs of inflammation
  • no sepsis
  • no SIRS

Non Cytosorb recipients

Patients not receiving Cytosorb due to septic shock.

Patients not treated with CytoSorb under suspicion for inflammation, septic shock or SIRS will be searched for same characteristics as the first group.

These groups will be matched when parameters like epidemiology, infectious parameters, prognostic scores, age, gender amount of catecholamines fit best.
