CLINICAL STATISTICS AND EFFECTIVENESS OF DIFFERENT TREATMENTS OF IDIOPATHIC THROMBOCYTOPENIC PURPURA

Aim. To ascertain efficacy of modern treatment methods in idiopathic thrombocytopenic purpura (ITP), to characterize basic indications for administration of these methods; perspective trends in ITP therapy. Material and methods. The article presents 20-year experience in observation and treatment of 1000 ITP patients gained from 1988 by the department of standardization of blood disease treatment methods on the basis of a consultative and outpatient department of Hematological Research Center. The results were assessed by conventional ITP treatment lines. Results. First-line therapy - glucocorticoids - provided remission in 70% patients, long-term (60 months and longer) in 14%, prednisolone resistance was in 19% patients. Intravenous immunoglobulin provided a rapid hemostatic effect (in 1-2 days) in all the patients. A positive response to treatment was seen in 86% patients but it was short-term (for a year and longer in 27%, resistance to the drug 14%). Second line treatment -splenectomy - is the most effective treatment: 80% remission, 32% patients had remission for longer than 60 months. Resistance occurred in 6% patients. Ineffectiveness of treatment in 20% patients stimulated the search for new pathogenetic treatment among synthetic analogues of thrombopoietin. Clinical trials proved high efficacy of two of them - eltrombopag and romiplostim (86-87% response), possible maintenance of remission in long-term interrupted administration of low doses. Conclusion. Modern ITP treatment allows a complete management of hemorrhagic syndrome and deep thrombocytopeny in 80% patients with provision of good quality of life and ability to work. Introduction into clinical practice of thrombopoietin analogues improves treatment results including in 20% patients resistant to all treatments in the absence of marked side effects even in long-term 3-year administration of such medication.
