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 transfusions and recently admitted with severe epistaxis refractory to platelet transfusion. At this stage administration of recombinant activated factor VII (fVIIa) was considered, which was initially given at 90 microg/kg dose with little control of bleeding but subsequent second dose of 120 microg/kg was administered with excellent response and immediate control of bleeding.

Background: Glanzmann thrombasthenia (GT) is a rare disease with an autosomal recessive inheritance pattern. This disorder is not so uncommonly encountered in routine clinical practice and laboratory settings in Pakistan let alone in the rest of the world. To describe the bleeding phenotype of GT and treatment outcomes in over one hundred patients in north Pakistan.

Background: Glanzmann thrombasthenia (GT) is a very rare autosomal inherited bleeding disease affecting megakaryocyte lineage with impacts on oral health such as gingival bleeding, which requires specific management protocols. Very few clinical cases have been published in the dental and hematologic literature.
Objectives: This study focuses on a series of 21 patients affected specifically by GT and their hemorrhagic prophylaxis management with the use of recombinant activated factor VII (rFVIIa) for dental extractions and full-mouth debridement.

Background: Platelet transfusion is considered the standard treatment for preventing or controlling severe haemorrhage in Glanzmann thrombasthenia (GT). However, platelet transfusion can have detrimental effects, including the production of anti-GPIIb/IIIa isoantibodies or anti-HLA antibodies (Ab) and platelet transfusion refractoriness. Recombinant activated factor VII (rFVIIa) has been proposed as an alternative treatment to platelet transfusion.
