DPP3 Forecasts Organ Failure in Burn Patients

DPP3 is a highly dynamic marker for predicting and monitoring cardiac depression in burn patients. It could be an indication for organ failure too.

High blood levels of Dipeptidyl Peptidase 3 (DPP3) indicate the upcoming multiple organ failure and death in burn patients, announced by the Diagnostics company SphingoTec GmbH ("sphingotec") and 4TEEN4 Pharmaceuticals GmbH ("4TEEN4").

DPP3 is a proprietary biomarker of 4TEEN4 for hemodynamic instability and cardiac depression. sphingotec has in-licensed global rights to develop and commercialize in vitro diagnostic (IVD) tests for the DPP3 biomarker from 4TEEN4 and made it available on its proprietary Nexus IB10 point-of-care platform.

Burns
Burn injuries have reached epidemic proportions in recent years. Burn accident statistics show that at least 50% of all burn accidents can be prevented.

‘The IVD test for DPP3, under the brand name IB10 sphingotest® DPP3, is designed and validated for use in conjunction with sphingotec's fully automated Nexus IB10 whole blood point-of-care platform to assess mortality risk in burn patients.’

The results from the recent study provide evidence that DPP3 blood concentrations in severely ill burn patients are indicating fatal outcomes. The data also shows that high DPP3 concentration in the blood is linked to circulatory failure, cardiac depression, and acute kidney injury. Decreasing DPP3 levels in the blood, on the other hand, indicate a substantially reduced risk of mortality.

According to a newly identified disease mechanism, the release of the cardiac depressant factor DPP3 into the bloodstream is a major cause of short-term organ failure: DPP3 is an enzyme that is present in many cell types and normally plays an important role in the recycling of cellular proteins.

When massive uncontrolled cell death occurs, like in the case of burn patients, DPP3 is released into the bloodstream where it degrades angiotensin II, a peptide hormone controlling the heart function.

Unphysiologically low levels of angiotensin II rapidly lead to cardiac depression and ultimately organ failure. Previously published data2,3 provided evidence that poor outcome of patients with severe heart failure or cardiogenic shock are caused by DPP3. Furthermore, the causal role of DPP3 in cardiac depression could be reproduced in several model systems.

"The new data adds to the growing body of evidence that places the cardiac depressant factor DPP3 in strong connection with short-term organ failure and high mortality in critical care settings. We have already started a collaboration with the critical care community to provide our fully automated DPP3 point-of-care test to support the management of acute care patients," said Dr. Andreas Bergmann, CEO and founder of sphingotec.

The IVD test for DPP3 is commercialized under the brand name IB10 sphingotest® DPP3 and is designed and validated for use in conjunction with sphingotec’s fully automated Nexus IB10 whole blood point-of-care platform, delivering results within 20 minutes.

This new test complements a wide-range of assays for acute care settings that are already available on this widely used point-of-care platform that can be flexibly deployed in laboratory as well as near-patient settings such as emergency departments and intensive care units.
