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...

LANZMANN’S THROMBASTHENIA is a wellG defined inherited disorder of platelet function.’.” It is caused by a deficiency or abnormality of the membrane glycoprotein (GP) IIb-IIIa complex with bleeding due to defective platelet hemostatic plug formation. Thrombasthenia has achieved much recognition for such a rare disease because it has been important in defining G P IIb-IIIa as a platelet receptor...

Patients whose platelets are deficient in glycoprotein (GP) Ib, IIb-IIIa (thrombasthenia), or granule substances (storage pool deficiency, SPD) were studied to define further the properties of platelets that mediate platelet adhesion and thrombus formation on subendothelium. Both nonanticoagulated and citrated blood were exposed to everted, de-endothelialized rabbit vessel segments under contro...

Background: Activated normal platelets undergo many biochemical and morphological changes, some of which are apoptotic. Platelet derived microparticles and shrinked platelets as hallmark of platelet activation and apoptosis disperse surfaces containing procoagulant activity around injured vessels and tissues. This study was conducted to determine microparticles formation and platelet shrinkage ...

BACKGROUND Two congenital bleeding diatheses have been identified in Thoroughbred horses: Glanzmann thrombasthenia (GT) and a second, novel diathesis associated with abnormal platelet function in response to collagen and thrombin stimulation. HYPOTHESIS/OBJECTIVES Platelet dysfunction in horses with this second thrombasthenia results from a secretory defect. ANIMALS Two affected and 6 clini...

Glanzmann thrombasthenia is an inherited auto-somal recessive disorder characterized by normal platelet count but lack of platelet aggregation due to absence of platelet glycoprotein IIb/IIIa. The disease usually is associated with mild bleeding, but severe fatal hemorrhage may occur. Allogeneic stem cell transplant is the only curative method of treatment. A literature search showed 18 previou...
