Snyder, M.D.: Telomerase Inhibitor Imetelstat in Patients with Necessary Thrombocythemia Essential thrombocythemia, a myeloproliferative neoplasm, is usually a clonal disorder of a multipotent hematopoietic progenitor cell.1,2 The condition is associated with an elevated risk of thrombotic complications, hemorrhagic complications, or both, and can evolve into myelofibrosis or, in rare cases, can transform to severe leukemia.3 Common mutations connected with essential thrombocythemia are found in the Janus kinase 2 gene, the gene encoding the thrombopoietin receptor , and the calreticulin gene.4-8 Current standard therapies for high-risk patients with essential thrombocythemia induce nonspecific reductions in platelet counts but do not typically eliminate or alter the biologic characteristics of the disease.9-12 We’ve reported that telomerase activity in malignant cells obtained from sufferers with essential thrombocythemia and induced telomerase activity in cells isolated from healthy donors were inhibited by the telomerase inhibitor imetelstat.13 However, imetelstat inhibited spontaneous proliferation of megakaryocytic colonies acquired from patients with essential thrombocythemia but did not inhibit cytokine-induced megakaryocytic colonies from healthy donors.
Around 80 % to 90 % of these occur among people 65 and older. To explore the possible association between your flu vaccine and stroke risk, the investigators pored over medical records of nearly 18,000 adult individuals in the United Kingdom who had experienced a stroke sometime between 2001 and 2009. All a flu vaccine has been received by the patients. But as the vaccine includes a maximum effectiveness of half a year just, the study team was able to compare the number of strokes happening within the 180 days following inoculation to the amount of strokes that happened after 180 days. The team observed an instantaneous 55 % plunge in stroke risk over the first three times following vaccination. And though stroke risk rose over the following days gradually, it remained 36 % lower between days four and seven; thirty % lower between times eight and 14; 24 % lower between days 15 and 28, and 17 % lower between days 29 and 59.
