Heparin induced thrombocytopenia

Common Name(s)

Heparin induced thrombocytopenia

Heparin-induced thrombocytopenia (HIT) is an adverse reaction to the drug heparin resulting in an abnormally low amount of platelets (thrombocytopenia). HIT is usually an immune response which typically occurs 4-10 days after exposure to heparin; it can lead to serious complications and be life-threatening. This condition occurs in up to 5% of those who are exposed to heparin. Characteristic signs of HIT are a drop in platelet count of  greater than 50% and/or the formation of new blood clots during heparin therapy.  The first step of treatment is to discontinue and avoid all heparin products immediately. Often, affected individuals require another medicine to prevent blood clotting (anticoagulants).

[Treatment of heparin-induced thrombocytopenia with rivaroxaban. Case report].
 

Author(s): Gustavo Rivera O, Oscar Corsi S, Andrés Pavlovic J, Andrés Aizman S, Pablo Varas A

Journal: Rev Med Chil. 2017 Sep;145(9):1213-1217.

 

Heparin-induced thrombocytopenia (HIT) is immune-mediated. It occurs more frequently with unfractionated heparin (UFH) than with low molecular weight heparins (LMWH). It is associated with thromboembolic rather than hemorrhagic events, as opposed to thrombocytopenia of other etiologies. ...

Argatroban for Heparin-Induced Thrombocytopenia during Venovenous Extracorporeal Membrane Oxygenation with Continuous Venovenous Hemofiltration.
 

Author(s): Jonathan H Sin, Natasha D Lopez

Journal: J Extra Corpor Technol. 2017 06;49(2):115-120.

 

Patients receiving extracorporeal membrane oxygenation (ECMO) are at risk of circuit thrombosis due to constant contact between blood and the extracorporeal components. Unfractionated heparin has traditionally been used in this setting as a systemic form of anticoagulation to prevent ...

Rapid immunoassays for diagnosis of heparin-induced thrombocytopenia: Comparison of diagnostic accuracy, reproducibility, and costs in clinical practice.
 

Author(s): Andriyana Bankova, Yvonne Andres, Michael P Horn, Lorenzo Alberio, Michael Nagler

Journal:

 

Immunoassays are crucial in the work-up of patients with suspected heparin-induced thrombocytopenia (HIT) and rapid tests have been recently developed. However, comparative data on diagnostic accuracy, reproducibility, and analytical costs of different immunoassays in clinical practice are limited.

Functional Assays in the Diagnosis of Heparin-Induced Thrombocytopenia: A Review.
 

Author(s): Valentine Minet, Jean-Michel Dogné, François Mullier

Journal:

 

A rapid and accurate diagnosis in patients with suspected heparin-induced thrombocytopenia (HIT) is essential for patient management but remains challenging. Current HIT diagnosis ideally relies on a combination of clinical information, immunoassay and functional assay results. Platelet ...

Journal: Acta Otorhinolaryngol Ital. 2016 Dec;36(6):527-533.

 

Heparin-induced thrombocytopenia and thrombosis (HITT) represents a dramatic condition that is difficult to diagnose because of nuanced clinical presentation. Therefore, in every case of microvascular thrombosis during heparin-therapy prompt suspicion about HITT is necessary to avoid ...
