It is now well established that the target antigens of platelet auto-antibodies are the GP IIb/IIIa and GP Ib/IX receptors. In our study, it was observed that the majority of patients had antibodies directed towards the GP IIb/IIIa receptor, whereas the number of patients having antibodies directed towards the GP Ib/IX receptor was much less. Also, we found that the patients in whom the auto-antibodies are directed towards the GP IIb/IIIa receptors usually have mild bleeding. On the other hand, the patients having auto-antibodies directed towards both GP IIb/IIIa and GP Ib/IX receptors have a severe bleeding diathesis, and usually show poor prognosis to treatment with corticosteroids.
