Managing thrombocytopenia associated with cancer chemotherapy.
Thrombocytopenia is a common problem in cancer patients. Aside from bleeding risk, thrombocytopenia limits chemotherapy dose and frequency. In evaluating thrombocytopenic cancer patients, it is important to assess for other causes of thrombocytopenia, including immune thrombocytopenia, coagulopathy, infection, drug reaction, post-transfusion purpura, and thrombotic microangiopathy. The incidenc...
متن کاملRecombinant human thrombopoietin: basic biology and evaluation of clinical studies.
Thrombocytopenia is a common medical problem for which the main treatment is platelet transfusion. Given the increasing use of platelets and the declining donor population, identification of a safe and effective platelet growth factor could improve the management of thrombocytopenia. Thrombopoietin (TPO), the c-Mpl ligand, is the primary physiologic regulator of megakaryocyte and platelet devel...
متن کاملThe biology of thrombopoietin and thrombopoietin receptor agonists.
Thrombopoietin (TPO) is the major physiological regulator of platelet production. TPO binds the TPO receptor, activates JAK and STAT pathways, thus stimulating megakaryocyte growth and platelet production. There is no "sensor" of the platelet count; rather TPO is produced in the liver at a constant rate and cleared by TPO receptors on platelets. TPO levels are inversely proportional to the rate...
متن کاملClinical indications for thrombopoietin and thrombopoietin-receptor agonists.
Thrombocytopenia is a common hematologic disorder. Stimulation of thrombopoiesis may reduce the risk for thrombocytopenia-induced bleeding, prevent severe thrombocytopenia, and reduce the need for platelet transfusion. The key cytokine is thrombopoietin (TPO). It regulates proliferation and maturation of megakaryocytes as well as platelet production. TPO is synthesized in the liver. Development...
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...
