How might gray platelet syndrome (GPS) be treated?

There is no specific treatment for GPS, but management involves anticipating and preventing risks of bleeding (e.g. possible platelet transfusions before surgery). Treatment may also include administration of desmopressin. Splenectomy should be considered to increase the platelet counts in those whose platelet counts decrease to approximately 30,000/microliter. Prognosis is generally good early in life when thrombocytopenia is mild. Those with platelets counts less than 30,000/microliter are at risk for life-threatening bleeding.[1]
