Fifty three
adult patients with
idiopathic thrombocytopenic purpura (
ITP) were diagnosed at the
University District Hospital (UDH) during the last 10 years (1976-1986). There were 33
females (62%) and 20
males (38%). All the
patients were over 15 years old with a mean age of 3o years. Only 13
patients gave a
history of a viral
syndrome preceding the onset of symptoms. The most frequent chief complaint was
petechiae and/or ecchymotic lesions. The mean initial
platelet count was 10,000/mm.
Bone marrow aspiration showed an increased number of
megakaryocytes without
platelet production in 49
patients (86%). Of the fifty three
patients, 37 (70%) had a complete response to
steroids. Of those not responding to
steroids, 15 underwent
splenectomy and 11 (73%) achieved a permanent response. Immunosupresion was prescribed in 4
patients with a 50% complete response
