BACKGROUND Thrombocytopenia in cirrhotic patients may be due to deficient production of thrombopoietin. AIMS To determine the relation between thrombopoietin and thrombocytopenia in cirrhotic patients before and after orthotopic liver transplantation. METHODS Thrombopoietin concentrations and platelet counts were measured in 43 cirrhotic patients and 21 normal controls and serially for 14 d...
Thrombopoietin receptor agonists (TPO-RAs) are used as effective alternative treatments in ITP patients unresponsive to first-/second-line therapies. TPO-RAs can also be used to normalize platelet count to safely perform invasive procedures and chemotherapy, in case of malignancies. In few responsive patients, TPO-RAs can be suspended maintaining a sustained response.
Severe aplastic anemia (SAA) has an aggressive clinical course and represents a “difficult-to-treat” situation with current medications [1]. Eltrombopag is a c-mpl receptor agonist oral thrombopoietin-mimetic drug, mainly active in immune thrombocytopenic purpura (ITP) [2]. Single-agent oral eltrombopag produced hematological responses in 11 of 25 cases of aplastic pancytopenia, with trilineage...
To evaluate whether the serum thrombopoietin levels in pregnancy-associated immune thrombocytopenia (ITP) differ from those in gestational thrombocytopenia, and reveal the possibility of thrombopoietin serving as a marker for differential diagnosis. Serum thrombopoietin concentration was determined in ITP in pregnancy (n = 35), gestational thrombocytopenia (n = 31), healthy pregnancy (n = 32), ...
The effects of administration of partially purified human urinary erythropoietin and rabbit thrombopoietin, and of endogenously produced erythropoietin and thrombopoietin on both red cell and platelet production were examined in mice. Partially purified thrombopoietin was prepared from rabbit plasma by sequential fractionation with ammonium sulfate precipitation, and DEAE and Sephadex G-100 chr...
A cDNA for the thrombopoietin has been cloned by several groups. The recombinant thrombopoietin has been reported to stimulate the megakaryocytopoiesis and thrombopoiesis. Little is known regarding the molecular basis of its effects. To elucidate the molecular mechanism involved in signal transduction, we have investigated the effects of thrombopoietin on platelet tyrosine phosphorylation. We r...
