In critical care settings, one of the main causes of organ failure and ultimately mortality is loss of endothelial function, which is associated with leakage of blood vessels. Although the symptoms of loss of endothelial functions are well-known, there are currently no simple, blood-based detection methods established for monitoring the worsening and improvement of endothelial function.
bio-ADM® can easily be measured in the blood enabling the assessment of the endothelial function up to 48 hours before the symptoms become visible. Regular assessment of the bio-ADM® levels allows for the monitoring of critically ill patients.
- is a blood-based parameter for quantifying the levels of bioactive Adrenomedullin
- aids in the early prediction of shock and vasopressor demand in critically ill patients
- allows monitoring of the endothelial function
- is independent from inflammation or any other comorbidities
- aids in the diagnosis of residual congestion
- has been validated in more than 22,000 patients
The relevance of endothelial function in critical care
Research has identified bioactive Adrenomedullin as a controlling hormone of the endothelial barrier, the interior wall protecting the blood vessels (2a). The median bio-ADM® concentration of 200 healthy subjects was 20.7 pg/mL; the 99th percentile was 43 pg/mL.
In certain conditions such as septic shock, cardiogenic shock or acute heart failure, the endothelial barrier becomes leaky, and additional bio-ADM® is produced to re-seal the barrier. However, bio-ADM® has a second function. It also expands the blood vessels, resulting in a dangerous blood pressure drop, which leads to shock and may ultimately escalate into multiple organ failure (2b).
The assay for the endothelial function biomarker bioactive Adrenomedullin
IB10 sphingotest® bio-ADM® is a rapid point-of-care (POC) immunoassay for the quantitative in vitro determination of bioactive Adrenomedullin (bio-ADM®) in human EDTA whole blood or plasma.
