[Treatment of idiopathic thrombocytopenic purpura in adults with high-dosage immunoglobulins].

Four of five patients with idiopathic thrombocytopenic purpura (ITP) responded to high-dose immunoglobulin treatment with transitory rise in platelet count to normal values, while the fifth had only minimal improvement. In the individual case there was good correlation between serum-IgG concentration and platelet count, but an influence on platelet-associated IgG could not be demonstrated with certainty. Treatment with high-dose IgG is apparently particularly suitable for patients with ITP refractory to steroids or splenectomy, in whom bleeding complications or operative procedures make a transitory rise in platelet count desirable.
