This anti-IIa activity can lead to an overestimation of argatroban's activity when switching to an anti-IIa anticoagulant such as argatroban. This situation can be critical because argatroban is generally administered following heparin therapy due to suspected heparin-induced thrombocytopenia. Therefore, there is both a significant thrombotic risk induced by the underlying condition and a hemorrhagic risk induced by the anticoagulation. For this reason, it is important to be able to accurately monitor the anti-IIa activity of argatroban. To date, the test used to determine the anti-IIa activity of argatroban at the Hematology Laboratory of the Strasbourg University Hospitals (HUS) is a modified thrombin time (with a calibration curve adapted for argatroban). When switching between several molecules with anti-IIa activity, this test does not allow for the differentiation of the anti-IIa activity attributable to each anticoagulant.\n\nThere are no data in the literature to determine whether heparins interfere with this test, and if so, its extent.",[47],"Thromboembolic Disease",[47,49,50,51,52,53],"HEPARINS","ARGATROBAN","Unfractionated heparin (UFH)","Low molecular weight heparins (LMWH)","Anti-Xa and anti-IIa activity","2025-12-10",{"date":56,"type":57},"2025-12-24","ACTUAL",{"date":59,"type":57},"2024-12-03",{"date":61,"type":43},"2026-01",{"name":5,"class":6},1]
