Glanzmann thrombasthenia (GT) is an inherited bleeding disorder due to either absence or dysfunction of fibrinogen binding receptors, i.e either GPIIb (GPIIβ) or GPIIIa (GPIIIα) on platelet membrane. The complete fibrinogen receptor, i.e. GPIIβGPIII which binds fibrinogen on activated platelets involves association of these two glycoproteins. Absence of either or both of these receptors can, th...

Glanzmann's thrombasthenia (GT) is a rare, genetically inherited platelet disorder in which the platelet glycoprotein IIb/IIIa (GP IIb/IIIa) complex is either deficient or, dysfunctional. The incidence is about 1 in 1,000,000. This case report deals with a 4 year-old girl diagnosed with GT presenting with dental caries and periapical lesions in the primary mandibular first molars. To provide th...

Glanzmann's thrombasthenia is an autosomal recessive inherited platelet function defect. Though, quantitatively normal, the aggregation ability of platelets is reduced leading to bleeding episodes requiring transfusion of platelet concentrates. We describe a case of 13-year-old girl who had recurrent episodes of epistaxis since birth and was managed with multiple platelet concentrate transfusio...

The molecular nature of platelet receptors for quinineand quinidine-dependent antiplatelet antibodies (Q.Ab and Qd.Ab) was studied by immunoblotting. One Q.Ab caused quinine-dependent lgG binding to platelet proteins with molecular weights (mol wts) of 1 74 Kd and 93 Kd and another to only a 93-Kd protein. A third Q.Ab caused binding to 1 74-. 140-. 93-. and 57-Kd proteins, while a fourth Q.Ab ...
