The mechanisms responsible for the low platelet count in idiopathic thrombocytopenic purpura are not well understood despite the careful studies by many competent investigators. The thrombocytopenia has been attributed to:
1. A decrease in the rate of platelet formation from megakaryocytes1, 2 because of splenic inhibition of these cells;3, 4, 5, 6
2. An increase in the rate of platelet destruction by the spleen,7, 8, 9, 10, 11, 12 and
3. A combination of damage to both megakaryocytes and circulating platelets.13, 14
Evidence to support the latter concept has been presented recently. A thrombocytopenic factor which damages circulating platelets and
