Idiopathic thrombocytopenic purpura in the elderly.

Idiopathic thrombocytopenic purpura (ITP) was diagnosed in 22 patients above the age of 50 during a seven-year period. There was no female preponderance. Steroid therapy was effective, particularly in preventing hemorrhage and is considered to be the treatment of choice. Splenectomy may be less beneficial than in younger patients with ITP. Complications of the disease and its treatment are minimal.
