New thrombopoietic growth factors.
Thrombopoietin (TPO) is the physiologic regulator of platelet production and works by binding to its receptor on megakaryocyte precursor cells, thereby activating a large number of antiapoptotic and cell maturation pathways. "First-generation" recombinant forms of TPO were developed over a decade ago and were found to increase the platelet count in patients undergoing nonmyeloablative chemother...
متن کاملNew therapies Haemopoietic growth factors
Haemopoietic growth factors are involved in the production of the various blood cells from progenitors in the bone marrow, making them useful in a range of clinical situations. The genes for several of them have been cloned and their production engineered by recombinant technology, making them widely available. Myeloid growth factors are used to support patients in the aftermath of chemotherapy...
متن کاملNovel thrombopoietic agents.
Thrombocytopenia is a primary manifestation of immune thrombocytopenic purpura (ITP) and may occur as a result of hepatitis C, malignancy, and treatment with chemotherapy. There is a need for additional means to treat thrombocytopenia in these settings. Recombinant thrombopoietin-like agents became available after the cloning of thrombopoietin in 1994. In clinical trials, these agents showed so...
متن کاملThrombopoietic activity in preterm newborns and infants.
Platelet count and thrombopoietic activity were investigated in preterm infants at birth and during their first four months of life. Thrombopoiesis stimulating factor activity in cord serum was significantly lower than that of adults and of the respective mothers. No difference was noted between thrombopoietic activity in cord serum in the various gestational ages studied--that is, 24 through 3...
متن کاملThrombopoietic factors in chronic bone marrow failure states: the platelet problem revisited.
Thrombocytopenia is a serious clinical problem in several different clinical settings. In chronic bone marrow failure states, which include aplastic anemia, myelodysplastic syndrome, and graft failure, the prolonged nature of thrombocytopenia often leads to alloimunization after repeated platelet transfusions, the consequence of which is a platelet-refractory state and enhanced risk of bleeding...
