[Pulmonary hypertension in chronic myeloproliferative disorders].
We report on three autopsy cases with clinical and morphological evidence of pulmonary hypertension and concurrent myeloproliferative disorders. Massive accumulations of pleomorphic, atypical megakaryocytes and thrombotic material are found within the pulmonary capillary beds. Morphometrical studies allowed us to identify on average 1,293.4 (1,145.8-1,401) megakaryocytes per one square centimet...
متن کاملPulmonary hypertension in patients with chronic myeloproliferative disorders.
Pulmonary hypertension (PH) is a severe haemodynamic disorder in which the pulmonary artery pressure is persistently elevated, leading to right-sided heart failure and death. Recently, chronic myeloproliferative diseases associated with pulmonary hypertension were included in the group 5 category, corresponding to PH for which the aetiology is unclear and/or multifactorial. In this review we wi...

STUDY OBJECTIVE To assess the incidence of pulmonary hypertension (PH) in patients with chronic myeloproliferative disorders (CMPD). METHOD Twenty-seven patients with a diagnosis of CMPD were included in the study. Patients were excluded if they had a secondary cause of PH.

JAK2, an acquired mutation of JAK2, is present in a majority of patients with polycythemia vera and to a lesser extent among patients with the other myeloproliferative disorders. We analyzed the effect of JAK2 on the expression of polycythemia rubra vera 1(PRV-1), using an in vitro model. Compared to wild-type JAK2, the presence of JAK2 increased both PRV-1 protein and mRNA levels in murine mye...
متن کاملChronic myeloproliferative disorders.
The Philadelphia chromosome-negative chronic myeloproliferative disorders (CMPD), polycythemia vera (PV), essential thrombocythemia (ET) and chronic idiopathic myelofibrosis (IMF), have overlapping clinical features but exhibit different natural histories and different therapeutic requirements. Phenotypic mimicry amongst these disorders and between them and nonclonal hematopoietic disorders, la...
