Active clinical trials for "Myeloproliferative Disorders"

Pulmonary hypertension (PH) is defined as a group of diseases characterised by an elevated mean pulmonary artery pressure (Ppa) ≥25 mmHg at rest. Recently, chronic myeloproliferative diseases (CMPD) associated with pulmonary hypertension were included in the group 5 category, corresponding to PH for which the aetiology is unclear and/or multifactorial. CMPD include chronic myelogenous leukaemia, chronic neutrophilic leukaemia and chronic eosinophilic leukaemia (which primarily express a myeloid phenotype and polycythaemia vera), idiopathic myelofibrosis, and essential thrombocytosis in which erythroid or megakaryocytic hyperplasia predominates. The purpose of this research: Assess Prevalence of PH in patients with CMPD in Northern Israel Describe the demographics and clinical course in patients with CMPD who are diagnosed with PH.

Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. Portal vein thrombosis and portal cavernoma frequently occur in the MPN population and the management of gastroesophageal varices in these patients are sometimes technically difficult. The aim of this study is to investigate the the characteristics of patients with gastroesophageal varices and portal caver cavernoma with or without JAK2 mutation.

Pulmonary hypertension (PH) is a complex condition that may be related to many clinical conditions. It is a serious disorder with a high morbidity and mortality rates. PH is classified into five groups according to clinical characteristics, pathological findings, hemodynamic characteristics and treatment response (Galie N, et al., 2016). These five groups include pulmonary arterial hypertension, PH due to left sided heart disease, PH due to lung disease and/or hypoxia, chronic thromboembolic pulmonary hypertension, or other pulmonary arterial obstruction and PH with unclear and/or multifactorial mechanisms (Simonneau G, et al., 2013). PH is a major complication of several hematologic disorders including myeloproliferative neoplasms (MPNs). MPNs are a group of diseases characterized by uncontrolled proliferation of at least one myeloid series due to an abnormal hematopoietic cell clone. There are different types of MPNs including polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) & chronic myeloid leukemia ( CML). Myeloproliferative neoplasms (MPNs) are included in group 5 PH (Arber DA, et al., 2016). This study will analyze the clinical and laboratory data of MPNs patients and correlate them with development of PH in these patients aiming to identify parameters that can predict PH in MPNs patients and thus, identifying MPNs patients at highest risk for PH who require close monitoring & screening for PH hoping that early detection and management of PH in MPNs patients can improve morbidity, prognosis and survival in those patients
