Immune thrombocytopenic purpura (ITP) causes thrombocytopenia through the autoimmune destruction of platelets. Corticosteroids remain the first line of therapy, and traditionally splenectomy has been the second. While the availability of thrombopoietin receptor agonists (TPO-RAs) has expanded treatment options, there is little data for the ideal management of these agents in preparation for spl...
Immune thrombocytopenia (ITP) is an autoimmune disease characterized by increased platelet destruction and impaired platelet production. In this study, we conducted a systematic review and meta-analysis to determine the efficacy and safety of thrombopoietin receptor agonists (TPO-RAs) in primary ITP patients. Thirteen randomized controlled trials were included in this study, the pooled results ...
The molecular mechanisms that underlie the favorable effects of thrombopoietin on stem cell survival, self-renewal, and expansion are unknown. On the basis of known effects of HoxB4, HoxA9, and vascular endothelial cell growth factor on stem cells, we explored whether TPO might affect these pathways. We found that TPO enhances the transcription of HoxB4, induces the nuclear localization of HoxA...
Little is known about the behaviour of endogenous thrombopoietin (TPO) serum levels during rapid sequences of dose-intensified chemotherapy. To characterize the relationship between TPO levels and platelet counts in this setting we serially measured both parameters over the entire treatment period of patients receiving multicycle polychemotherapy. We found TPO and platelet responses to be gener...
A sensitive immunoassay procedure for the detection of the thrombopoietic-stimulating factor (TSF) has been developed. This procedure Is similar to the hemagglutination-inhibition (HAl) technique that is available for erythropoietin. For the production of TSF, sheep were made thrombocytopenic by the Injection of antiplatelet serum. TSF from sheep sera was partially purified by column chromatogr...
The coagulopathy of chronic liver disease causes derangement the results traditional laboratory tests. As such, there is an expectation that when undergoing invasive procedures patients with cirrhosis are at increased risk bleeding. Standard practice to optimise values prophylactic transfusions platelets, plasma and fibrinogen reduce perceived bleeding risk. There has been a shift in thinking r...
