[Effective danazol therapy for a patient with Evans syndrome].

Danazol administered to a 66-year-old man with Evans syndrome, which was refractory to prednisolone therapy and pulse therapy with methylprednisolone. Danazol therapy produced an excellent and sustained improvement, increasing platelet counts and Hb concentrations. Recently, danazol therapy has been reported to be of benefit to severe idiopathic thrombocytopenic purpura (ITP) and autoimmune hemolytic anemia (AIHA). And this case marked a favorable effect also on Evans syndrome, which has both characters as ITP and as AIHA. The aim of this paper is to suggest that the administration of danazol has a positive effect on Evans syndrome and probably on other various thrombocytopenic diseases and syndromes, especially on refractory cases.
