Interferon-alpha 2b is not effective in the treatment of refractory immune thrombocytopenic purpura

About 25-30% of patients with immune thrombocytopenic purpura (ITP) are refractory to corticosteroids, splenectomy and other treatments. It has been suggested that interferon-alpha 2b (IFN-alpha 2b) may be useful in the treatment of chronic refractory ITP patients. We treated 9 chronic refractory ITP patients with IFN-alpha 2b: the results were poor.
