Glanzmann, thrombasthenia

[MIM 273 800]

Unknown prevalence. Autosomal recessive transmission. Hemorrhagic thrombopathic disorder characterized by an absence of platelet aggregation due to an quantitative or qualitative anomaly of a membrane receptor (glycoprotein: integrin aIIbβ3) on the platelet surface. Several of the genes (ITGA2B on 17q21.31 and ITGB3 on 17q21.32) involved in the synthesis of the  glycoprotein IIb/IIIa complex (or fibrinogen receptor) can be affected. This anomaly causes bruising even after minor trauma, frequent mucosal bleeding (gums, nose) but rarely spontaneous bleeding except during menstruation, after trauma or after surgery (or childbirth). 


Depending on the severity of the platelet deficit and depending on the extent of the deficiency in platelet

glycoprotein IIb/IIIa, 3 types are described:


-         type I (severe): level < 5 % of normal; low or absent binding to fibrinogen and absence of clot retraction.

-         type II (less severe): level between 5 % and 20 %; binding to fibrinogen  is present and clot retraction normal or partial.

-         type III (not severe): level > 50 %, no significant abnormality of platelet aggregation; binding to fibrinogen and retraction of the clot are variable.


Some rare acquired cases exist due to the presence of autoantibodies directed against the membranar aIIbβ3 glycoproein.

Diagnosisaccording to the type, hemorrhage when the umbilical cord falls, prolonged bleeding, profuse menstrual bleeding



Anesthetic implications: 

Contact a specialist in hemostasis. Contraindication to perimedullary anesthesia and retrobulbar blocks. Avoid intramuscular injections and rectal or nasopharyngeal temperature measurement. Insert central venous catheters under ultrasound guidance, and provide prolonged local compression when removing them.

In case of bleeding: local compression, tranexamic acid (10 mg/kg every 8h. IV or p os).

In the event of severe bleeding: administer platelets 1 hour before surgery, then every 12 to 24 hours. Paradoxically, the number of units to be transfused to correct hemostasis is higher than in case of thrombocytopenia, as the donor platelets mix with the defective recipient platelets. 

The thromboelastogram is useful for assessing platelet function.

If antiplatelet antibodies are present  (against the complex GP IIb-IIIa or antigen of the HLA system) or if blood platelets are not available:  administration of at least 3 doses of recombinant activated factor VII (Novoseven®) at a dose of 90 µg/kg every 2 h.

Do not administer any drugs affecting platelet function: aspirin,NSAIDs. In case of pregnancy in a mother carrying anti GP IIb-IIIa antibodies following platelet transfusions, transient thrombocytopenia can appear in the fetus and the newborn.
