Acquired thrombasthenia due to inhibitory effect of glycoprotein IIbIIIa autoantibodies.
BACKGROUND A 75 year old patient presenting with mucocutaneous bleeding was diagnosed with acquired thrombasthenia. The diagnosis was based on lack of platelet aggregation with adenosine diphosphate (ADP), arachidonic acid and collagen, and normal aggregation induced by ristocetin. OBJECTIVE To study the mechanism of platelet function inhibition in a patient with acquired thrombasthenia. ME...
متن کاملGlanzmann thrombasthenia
Glanzmann thrombasthenia (GT) is a rare autosomal recessive bleeding syndrome affecting the megakaryocyte lineage and characterized by lack of platelet aggregation. The molecular basis is linked to quantitative and/or qualitative abnormalities of alphaIIb beta3 integrin. This receptor mediates the binding of adhesive proteins that attach aggregating platelets and ensure thrombus formation at si...
متن کاملGlanzmann thrombasthenia in a neonate.
Glanzmann thrombasthenia is a qualitative platelet function disorder manifested by skin bleeds, epistaxis, gingival bleeding, gastrointestinal hemorrhage, hematuria, hemarthrosis, intracranial hemorrhage and visceral hematomas. We report a six day old newborn presenting with hematuria following suprapubic aspiration, who was diagnosed as Glanzmann thrombasthenia. We believe it to be the younges...

متن کاملPatients With Glanzmann Thrombasthenia Lacking Platelet Glycoprotein
Background—Platelets have been suggested to play a role in the early development of atherosclerosis. As one test of this hypothesis, we assessed whether patients with Glanzmann thrombasthenia who lack platelet glycoprotein IIb 3 (GPIIb/IIIa) complexes or both IIb 3 and the more ubiquitous v 3 cell membrane complexes are protected from development of atherosclerosis. Methods and Results—Seven pa...
