Active clinical trials for "Thrombocytopenia"

Chemotherapy-induced thrombocytopenia (CIT) is a common hematological toxicity in patients with solid tumors undergo chemotherapy, which can increase the risk of bleeding, prolong hospital stay, increase medical costs, and even lead to death in severe cases. The incidence and severity of CIT varies among different chemotherapy regimens. Recombinant human interleukin-11 (rhIL-11) and recombinant human thrombopoietin (rhTPO) have been approved for the treatment of chemotherapy-induced thrombocytopenia. Tumor patients are at high risk for venous thromboembolism (VTE). In the clinical study of rhIL-11, it was found that the administration of rhIL-11 in healthy subjects caused an increase in the plasma concentration of vWF factor in the form of normal mults. The application of rhIL-11 in patients with myeloid leukemia can increase the concentration of α2 globulin, fibrinogen and prothrombin time. However, there have been no large-scale clinical studies at home and abroad to evaluate whether platelet raising therapy will increase the risk of thrombosis in chemotherapy patients with solid tumor. This study is aimed to evaluate the efficacy and safety of platelet upwelling therapy in patients with solid tumors undergoing chemotherapy.

The purpose of this study is to understand physician treatment decisions in selecting specific second line treatments in pediatric ITP and to determine the effectiveness of different second line ITP treatments. Eligible patients are those ages 1-18 years who are starting on a new second line treatment for ITP, defined as any treatment other than IVIG, steroids, anti-D globulin, or aminocaproic acid. Enrolled patients remain on the study for approximately one year.

The aim of this large French multicentric retrospective study was to compare the efficacy and safety of two (the standard and the Rheumatoid arthritis) rituximab regimens in adult's immune thrombocytopenia .

The aim of our study is to evaluate the efficacy of rapamycin with Refractory Immune Thrombocytopenic Purpura (RITP) and explore the further mechanism.

An indirect comparison to compare the efficacy of eltrombopag versus romiplostim

The purpose of this study is To describe patient characteristics and drug usage among children that are prescribed esomeprazole for the first time and to compare them with patients who are prescribed other proton pump inhibitors (PPIs) or H2-receptor antagonists for the first time. To ascertain all incident hospitalized cases of angioneurotic oedema, pneumonia, gastroenteritis, failure to thrive, convulsions/seizures, acute interstitial nephritis and thrombocytopenia among new users in the three cohorts of esomeprazole, other PPIs and H2-receptor antagonists.

Platelet transfusions are routinely administered during neonatal ECMO, with an average of 1.3 platelet transfusions per day being administered while a patient is undergoing ECMO treatment. The cause of thrombocytopenia during ECMO largely involves platelet adherence to the oxygenator membrane. Platelet transfusions carry risks such as infections with bacteria or yeast, and development or worsening of pulmonary hypertension. It is likely that if fewer platelet transfusions can be administered during the ECMO run, the cumulative adverse effects of platelet transfusions would diminish and patient outcomes improve. In order to better understand platelet function during ECMO, the investigators plan to serially determine the circulating platelet mass, plasma platelet factor 4 concentration, megakaryocyte mass (estimated by plasma thrombopoietin concentration), and platelet function as quantified by PFA100. Any patient on ECMO will be eligible for this pilot study of 5 patients. By understanding changes in platelet function, we hope to design a future study that may modify the frequency or need for platelet transfusions during ECMO.

PURPOSE The purpose of this study is to learn more about multifocal lymphangioendotheliomatosis with thrombocytopenia (MLT). MLT is a rare vascular disorder characterized by multiple congenital skin and visceral lesions, profound thrombocytopenia, and gastrointestinal bleeding. The skin lesions may appear red, brown or blue, often misdiagnosed as hemangiomas. The gastrointestinal tract, liver, and lungs are the most common internal organs involved. The severe thrombocytopenia (low platelets) is believed to be the result of platelet trapping within the skin and visceral vascular lesions. Severe and chronic gastrointestinal bleeding is common during infancy and early childhood. Although a relatively newly described entity, MLT was likely previously reported as hemangiomas, blue rubber bleb nevus syndrome, diffuse hemangiomatosis, Kasabach-Merritt phenomenon, and hereditary hemorrhagic telangiectasia. The term cutaneovisceral angiomatosis with thrombocytopenia is also a term used for this same disease. This study is a longitudinal cohort study of MLT to collect detailed clinical data on the distribution of disease, disease severity, and complications. This data will be used to create diagnostic criteria and an evaluation protocol for infants with this disease
