In general, the bleeding tendency in GT decreases with age. The survey consisted of 59 GT patients who were given rFVIIa as either treatment of hemorrhage or for surgical prophylaxis. Congenital bleeding disorders with long bleeding time and normal platelet count.
Bleeding problems can be severe in patients with Glanzmann thrombasthenia, but the prognosis remains good with appropriate supportive care. Large deletions are rare.

Deficiencies in the platelet response to arachidonic acid can point either to an inherited abnormality in thromboxane A2 formation or a platelet function defect temporarily acquired through aspirin ingestion.
To date, the single largest published investigation into the efficacy of rFVIIa in trobmastenia with GT was reported by Poon et al through an international survey. Sign Up It’s Free! Patients with GT also are not protected against venous thrombosis, where plasma coagulation factors are of primary importance [ 43 ].
Incidence and prevalence It is estimated that one in 1, individuals have GT, though the exact number is unknown. The stability of the newly-formed clot is increased and its permeability decreased [ 57 ].
A novel ProHis beta glanmzann mutation in integrin alphaIIb causes Glanzmann thrombasthenia by impairing progression of pro-alphaIIbbeta3 from endoplasmic reticulum to Golgi. Trombbastenia platelets might not have exactly the same friendly proteins on the surface. Iron replacement therapy may be recommended.
