The invention relates to novel compositions and to methods for the pulsed administration of compositions to a patient or to cells in vitro for the treatment of human blood disorders. Compositions contain chemical compounds that stimulate the expression of fetal hemoglobin and/or stimulate the proliferation of red blood cells, white blood cells and platelets in patients and ex vivo for reconstitution of hematopoiesis in vivo. These methods are useful to treat or prevent the symptoms associated with anemia, sickle cell disease, thalassemia, blood loss, and other blood disorders. The invention also relates to methods for the pulsed administration of compositions to patients for the treatment and prevention of cell proliferative disorders including deficiencies such as cytopenia and malignancies and for expansion of cells for hematopoietic transplantation. Pulsed administration has been shown to be more effective than continuous therapy in patients tested.
本发明涉及新型组合物以及向患者或体外细胞脉冲施用组合物治疗人类血液疾病的方法。组合物含有刺激胎儿血红蛋白表达和/或刺激患者体内和体外红细胞、白细胞和血小板增殖的化合物,用于体内造血重建。这些方法可用于治疗或预防与贫血、镰状细胞病、地中海贫血、失血和其他血液疾病有关的症状。本发明还涉及向患者脉冲式施用组合物的方法,用于治疗和预防细胞增殖性疾病,包括细胞减少症和恶性肿瘤等缺陷,以及用于造血移植的细胞扩增。在测试的患者中,脉冲给药比连续治疗更有效。
