Objectives: Heparin is given for anticoagulation during and after pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension. Our objective was to add to the limited data available on the incidence, management, and outcomes of suspected heparin-induced thrombocytopaenia after pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension.
Methods: This retrospective single-centre study included consecutive patients with suspected heparin-induced thrombocytopaenia after pulmonary thromboendarterectomy done in 2005-2018.

Unlabelled: Heparin-induced thrombocytopenia (HIT) is an immune-mediated disease with severe thromboembolic complications. HIT during percutaneous coronary intervention (PCI) can be fatal without prompt treatment. We report an unusual case of HIT observed during PCI for acute coronary syndrome (ACS).

(1) Background: Danaparoid sodium is a heparinoid antithrombotic that has been used for over 40 years for prophylaxis of DVT in non-HIT patients and for the treatment of heparin-induced thrombocytopenia (HIT) with and without thrombosis. This update summarises current information on its pharmacology and reviews danaparoid dose management in a broad spectrum of clinical situations, including off-label indications. (2) Methods: Evidence from published clinical studies, case reports, compassionate use of danaparoid, and spontaneously reported serious adverse events is summarised and analysed by an interdisciplinary expert group to develop a consensus on dosing regimens of danaparoid for complex clinical situations, including vulnerable patient populations.

Background: Heparin-induced thrombocytopenia (HIT) is a potentially life-threatening adverse drug reaction with numerous diagnostic challenges. Diagnosis of HIT begins with 4T score clinical assessment, followed by laboratory testing for those not deemed low risk. Laboratory testing for HIT includes screening [enzyme-linked immunosorbent assay (ELISA)] and confirmatory [serotonin release assay (SRA)] assays, wherein SRA testing can be pursued following a positive ELISA result.
View Article and Find Full Text PDFHeparin-induced thrombocytopenia (HIT) is an adverse drug reaction with significant thromboembolic risk. Though there are models for use of non-heparin anticoagulants, heparin remains the preferred anticoagulant in many operative settings, especially cardiovascular surgery and percutaneous cardiac intervention. The natural history of HIT can be stereotyped into phases using HIT laboratory testing to guide clinical management and determine whether heparin re-exposure can be considered.
