The authors present the case of a 21-year old woman patient who was admitted to hospital because of typical symptoms of chronic idiopathic thrombopenic purpura. Prednisolone therapy alone and subsequently combined with Immuran as well as later applied large dose of Methylprednisolone failed to be effective. Owing to the ineffective therapies and increasing hemorrhagic diathesis splenectomy was performed under perioperative Venagamma protection without success. Intraglobin-F therapy brought perfect recovery. The authors review the expectable results of immunoglobulin therapy, the strategy of ITP therapy changed as a consequence of the new therapeutic possibility as well as the indications of immunoglobulin treatment.
