Sticky platelet syndrome
Sticky platelet syndrome is a term used by some[1][2][3][4] to describe a disorder of platelet function.[5]
It was first described by Mammen in 1983.[6]
It is inherited in an autosomal dominant pattern.[7]
It has not been associated with a specific gene, and it is not recognized as an entity in OMIM.
Among researchers using the term, it has been described as a coagulation disorder that can present in conjunction with protein S deficiency and Factor V Leiden.[8]
It is not currently known if sticky platelet syndrome is a distinct condition, or if it represents part of the presentation of a more well characterized coagulation disorder.
Diagnosis
SPS is diagnosed by demonstrating platelet hyperaggregability. In a lab test called aggregometry platelet stickyness is stimulated with epinephrine (EPI) and/or adenosine diphosphate (ADP).[9] This test is not possible for patients being treated with acetylsalicylic acid until that substance has sufficiently cleared from their system.
Treatment
Those diagnosed are usually treated with taking a low dose (80–100 mg) Aspirin a day.[10] Anticoagulants (e.g. Warfarin, Coumadin) or clopidogrel (Plavix) are often additionally prescribed following formation of a medically significant clot. Thrombelastography is more commonly being used to diagnose hypercoagulability and monitor anti-platelet therapy.
Criticism
Critics of the diagnosis complain that case evidence is spotty and lacking controlled clinical studies.[11]
