A diagnostic test for heparin-induced thrombocytopenia.

Heparin-induced thrombocytopenia can be a serious and difficult-to-diagnose complication of heparin therapy. Serum from patients with heparin-induced thrombocytopenia can cause heparin-dependent platelet aggregation, but the low sensitivity and specificity of this test limit its clinical usefulness. In this report we describe an assay for heparin-induced thrombocytopenia that is both sensitive ...

Heparin induced thrombocytopenia

Abstract Background and Objectives Heparin is still a commonly used anticoagulant in prophylaxis and treatment of thromboembolic events. Heparin-induced thrombocytopenia (HIT) is a life-threating adverse drug reaction of heparin. The diagnosis of HIT is made based on two important criteria, firstly clinical evaluation and secondly laboratory testing. In this comprehensive review, the authors w...

Novel diagnostic assays for heparin-induced thrombocytopenia.

Laboratory testing for heparin-induced thrombocytopenia (HIT) has important shortcomings. Immunoassays fail to discriminate platelet-activating from nonpathogenic antibodies. Specific functional assays are impracticable due to the need for platelets and radioisotope. We describe 2 assays that may overcome these limitations. The KKO-inhibition test (KKO-I) measures the effect of plasma on bindin...

Heparin-Induced Thrombocytopenia: Diagnostic and Therapeutic Considerations

INTRODUCTION Heparin use is ubiquitous in medicine today. It is used therapeutically in the management of arterial and venous thrombotic processes, such as acute myocardial infarction or deep venous thrombosis, and prophylactically to prevent thrombosis around the time of orthopedic procedures and to prevent prosthetic heart valve thrombosis or stroke in atrial fibrillation. Heparin is bonded t...

Heparin-induced thrombocytopenia: a review.

Immune heparin-induced thrombocytopenia (HIT) is a relevant adverse drug reaction consisting in a hypercoagulable state caused by an anticoagulant agent. The incidence is approximately 6.5% in patients receiving unfractionated heparin after orthopedic surgery, and is equal to or lower than 1% in other settings. HIT occurrence is a function of heparin type, duration of heparin administration, pa...
