Key result
Polybrene, P2Rho, and HEP-TEM effectively neutralize prophylactic and therapeutic LMWH and UFH in vitro.
Why the study?
Heparin therapy diminishes thrombin generation, causing the TG curve to not reflect the true hemostatic status of patients under treatment.
Can the in vitro addition of heparin antagonists restore the underlying thrombin generation capacity in samples containing heparin?
Population
Plasma samples from patients receiving heparin therapy
Comparison
In vitro addition of heparin antagonists (Polybrene, P2Rho, heparinase HEP-TEM) vs no antagonist
Design
Preclinical laboratory study

The addition of heparin antagonists like Polybrene, P2Rho, or heparinase HEP-TEM to the thrombin generation assay effectively neutralizes heparin, allowing for accurate assessment of underlying hemostatic status.

Benoit et al. (2021) studied Patients receiving heparin therapy. Polybrene, P2Rho, and heparinase HEP-TEM was evaluated on Neutralization of heparin. Polybrene, P2Rho, and heparinase HEP-TEM effectively neutralized heparin at prophylactic and therapeutical doses of both low molecular weight and unfractionated heparin in vitro.
