Active clinical trials for "Myeloproliferative Disorders"

Goal of the study is to assess the frequency of pulmonary hypertension in patients with chronic myeloproliferative diseases. In each patient an echocardiography at rest will be performed. In patients without musculoskeletal disease an exercise test (spiroergometry) will be performed. Patients with elevated SPAP at rest or with reduced exercise capacity (peak VO2 < 65%) a right heart catheterization (RHC) will be recommended. Also patients with advanced NYHA functional class (III or IV) or with typical PH findings in electrocardiogram will be advised to undergo a RHC. Additionally for the evaluation of exercise capacity a 6 MWD will be performed. This work- up of patients allows clinical and hemodynamic evaluation.

The incidence of secondary cancer (SC) in patients with myeloproliferative neoplasms (MPN) is high and comparable to that of thrombosis. However, the identification of patient subgroups that might be at increased susceptibility of developing SC has not been systematically addressed. This international case-control study (MPN-K) is aimed to elucidate the prognostic role of JAK2V617F mutation in predicting the occurrence of SC in patients with classical MPN, polycythemia vera (PV), essential thrombocythemia (ET) and myelofibrosis (MF)

The goal of this observational study is to evaluate the epidemiological and clinical-pathological features of Philadelphia-negative myeloproliferative neoplasms through data from medical records

Patients with myeloproliferative neoplasms Philadelphia chromosome negative (MPNsPh1-) such as Essential thrombocytosis (ET), Polycythemia vera (PV) and Primary Myelofibrosis (PMF) have a higher risk of arterial or deep-vein thrombosis. This is responsible for a significant increase in mortality (up to 31% of increase in thrombosis risk in ET). Cellular inflation and blood hyperviscosity, resulting from these diseases, fail to account for these thromboses, as more than 50% of thrombotic complications happen under adapted antineoplastic drug treatment. These last years, cellular microparticles (MPs) have been shown to play a major role in thrombogenesis. MPs are generated by apoptosis or the activation of malignant cells, platelets, endothelial cells or monocytes. They are fragments of plasma membrane, smaller than 1 µm, rich in phosphatidylserine, which can express the tissue factor and serve as support for the coagulation factors. Increase in the plasma concentration of procoagulant platelet microparticles has been demonstrated in other thrombotic diseases (acute coronary syndrome, disseminated intravascular coagulation DIC, etc.). The working hypothesis is that platelet microparticles are involved in the hypercoagulability of MPNs patients.

Currently, there is no accurate way of predicting the occurrence of Graft vs Host Disease (GvHD) or infection. The purpose of this study is to analyze blood with the ImmuKnow® Assay to see if doctors can detect which patients are at risk for GvHD and for getting an infection before they occur.

The primary objective of this study is to examine transplant related mortality (TRM) at 100 days <30%. A TRM of >50% is considered unacceptable. This study also seeks a TRM at 12 months that is <50%, engraftment >90% (defined as donor cells >80% at 6 months), and 1 year overall survival >50%.

Enrolled MPN patients will participate in a podcast intervention via a smartphone app. They will listen to 60 minutes per week of podcasts through this app, which consist of cancer-related health education material. Participants have the option to listen to additional podcasts beyond the 60-minute weekly prescription if they desire. Participation will be tracked through self-report logs. In addition, questionnaires will be administered at baseline, midpoint (week 6), and post-intervention (week 12), which ask about demographics, health information, and satisfaction. The hypothesis is that the smartphone app is feasible for delivering home-based health education podcasts to MPN patients.

The Fondazione per la Ricerca Ospedale di Bergamo (FROM) decided to propose and promote the completion of ERNEST registry: the aim of the project is to obtain up-to-date estimates of clinical outcome of these patients in primary and secondary Myelofibrosis that have been included in the 'original' ERNEST study. The last was conducted between 2012 and beginning of 2015 including 1292 patients with Myelofibrosis, but it was interrupted in 2015 because of bankruptcy of the previous sponsor.

Myeloproliferative disorders occur in families, thus giving rise to the theory that it is a genetic disease that may be caused by an abnormal gene in the DNA that can be passed from one generation of family members to another. DNA can be gathered from family members through blood samples and the investigators will investigate (through DNA testing) to see if there are abnormal genes that may be responsible for causing the MPDs. Understanding which genes are responsible for causing MPDs can help develop ways to identify people who may be at risk for developing an MPD, allow for the development of better treatments, possibly a cure, or even prevent the development of MPDs.

This study performs HLA matched stem cell transplantation from unrelated donors in adults who require stem cell transplantation but do not have a matched related donor available. The incidence of graft-versus-host disease in unrelated stem cell transplantation is recorded. This study also monitors the activity and toxicity of total body irradiation and cyclosphosphamide followed by stem cell transplantation from matched unrelated donors.
