Tropical spastic paraparesis or HTLV-I-associated myelopathy is a progressive spastic disorder associated with the human T-lymphotropic virus type I. Some cases have responded to prednisone. Danazol is an attenuated androgen with minimal vi…

Danazol, an attenuated androgen, is useful in endometriosis, idiopathic thrombocytopenic purpura (ITP), and autoimmune hemolytic anemia (AIHA). However, its mechanism of action is unknown. We investigated the possibility that danazol affect…

STUDY OBJECTIVE: To assess the long-term benefit and side effects of danazol therapy, and to delineate factors influencing the responses in patients with autoimmune thrombocytopenia. DESIGN: Before and after trial. SETTING: Referral-based h…

Danazol, an attenuated androgen, has been used successfully at its conventional dose (400-800 mg/day) in the treatment of idiopathic thrombocytopenic purpura (ITP). To minimize side effects, the authors tried a very low dose (50 mg/day) reg…

We evaluated the use of danazol in 15 patients with autoimmune hemolytic anemia of the warm antibody type. Danazol, 600 to 800 mg/d, was added to previous regimens or given initially in conjunction with high-dose prednisone treatment. Twelv…
