Anagrelide-associated cardiomyopathy in polycythemia vera and essential thrombocythemia.
نویسندگان
چکیده
A comprehensive database inquiry at our institutions identified 11 patients with echocardiogram-documented idiopathic cardiomyopathy that post-dated a diagnosis of either polycythemia vera or essential thrombocythemia. Anagrelide therapy was temporally associated with the particular complication in 6 patients, all of whom experienced symptomatic and/or objective improvement after drug discontinuation.

BACKGROUND AND OBJECTIVES Although anagrelide is widely used in the treatment of thrombocythemia in myeloproliferative diseases, there is currently limited information on the efficacy and toxicity of its long-term use. This prospective study investigated clinical toxicity and efficacy of anagrelide during two years of treatment. DESIGN AND METHODS A multicenter, open, phase II study of anagre...

BACKGROUND Although the platelet count does not correlate with the rate of thrombosis, there is evidence that a strict control of the platelet count decreases the incidence of thromboembolic complications in essential thrombocythemia. In the current study, the authors evaluated the efficacy and tolerability of anagrelide in thrombocytosis associated with myeloproliferative disorders. METHODS ...

Recent insights into the molecular mechanisms of polycythemia vera (PV) and essential thrombocythemia (ET) are challenging the traditional diagnostic classification of these myeloproliferative disorders (MPDs). Clonality analysis using X-chromosome inactivation patterns has revealed apparent heterogeneity among the MPDs. The recently discovered single somatic activating point mutation in the JA...

Background and Aim: The JAK2 is an acquired mutation that is observed in majority of patients with classical Philadelphia-negative Myeloproliferative neoplasms that include polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF). This acquired mutation is characterized by a G to T transversion at nucleotide 1849 in exon 12 of the JAK2 gene, leading to a substitution ...
