Diagnostic of Chronic Thrombocytopenia
Congenital ThrombocytopeniaChronic Idiopathic Thrombocytopenic PurpuraThe objective of this study is to provide simple and relevant clinical and biological elements to distinguish a possible Congenital Thrombocytopenia from a Chronic Idiopathic Thrombocytopenic Purpura .
Effect of Hemodialysis Membranes on Platelet Count
ThrombocytopeniaThe purpose of this study is to determine if there is a drop in platelet count after hemodialysis. Hemodialysis membranes are known to activate complement and cause a drop in platelets and sometimes in white blood cells. The investigators are going to study one of the membranes which is the Fresenius Optiflux® to check if it causes a drop in platelets.
Heparin Induced Thrombocytopenia: Pharmacoeconomics
Heparin Induced Thrombocytopenia (HIT)Patients at BWH receiving unfractionated heparin or enoxaparin who subsequently develop heparin induced thrombocytopenia will be identified via a computer generated report designed for the purposes of this study. Subsequently, we will compare the heparin induced thrombocytopenia rates associated with heparin and low molecular weight heparin usage as well as evaluate the economic and long-term clinical burden of heparin induced thrombocytopenia.
Occupational Status and Hematological Disease
Chronic Myeloid LeukemiaChronic Lymphocytic Leukemia3 moreDiseases do not only have a physical role in people's live, but they usually involve changes in life as whole. They may modify the structure of the conjunction with life setting, thus, deeply impacting relationships with others. While clinical results of new therapies for hematological diseases are well documented in scientific literature in terms of prolonged life expectancy or remission from disease, less is known about problems and barriers preventing the return of patients with a chronic blood ailment to everyday life. Indeed, there are no published data on this topic within the Italian context. The present explorative study aims at identifying the main problems with which patients affected by a Chronic Hematological Disease (CHD) deal when returning to everyday working life, factors associated with work reintegration and, finally, to understand the need for facilitators enhancing reintegration outcomes. Results from this study will be also helpful to raise consciousness about the problem of reintegration into the labour market of workers with CHD and to call for awareness campaigns for the general public and health professionals.
Bleeding Prediction in Thrombocytopenia
ThrombocytopeniaThe purpose of the study is to investigate whether platelet indices from automated haematology equipment, whole blood impedance aggregometry and a standardized bleeding questionnaire predict bleeding in admitted patients with thrombocytopenia of various causes.
The Neonatal Hemorrhagic Risk Assessment in Thrombocytopenia Study
ThrombocytopeniaThis is a prospective longitudinal study that evaluates Platelet Function Analyzer-100 (PFA-100) CT-ADPs (closure time-ADP) and incidence of bleeding using the Neonatal Bleeding Assessment Tool - Neo-BAT in preterm neonates <32 weeks gestational age or with a birth weight <1500 grams and with different degrees of thrombocytopenia. The investigators hypothesized that PFA-100 CT-ADP, a global in vitro test of primary hemostasis, will be a better predictor of clinical bleeding in neonates than platelet count alone. A bleeding risk assessment marker could help physicians more accurately determine the risk/benefit ratio of platelet transfusions, guiding platelet transfusion decisions in neonates with thrombocytopenia.
Evaluate the Association Between Infection and Thrombocytopenia
ThrombocytopeniaThe study is designed to evaluate the association between nosocomial bloodstream infection and the occurrence of thrombocytopenia in surgical critical ill patients.
Autoantibody Specificity and Response to IVIG in ITP
Immune Thrombocytopenia (ITP)The objective of this human study was to evaluate the association between the specificity of anti-platelet autoantibodies and response to IVIG treatment.
Patient Plasma Response and Outcome in Septic Shock With Thrombocytopenia Associated Multiple Organ...
Septic ShockThrombocytopenia1 moreThe purpose of this study is to learn how blood clotting substances respond in children with septic shock, low platelet counts, and multiple organ failure (MOF) treated at different institutions. Multiple organ failure can be related to an infection producing "septic shock," in which substances released in the blood cause poor blood flow to the organs. The number of platelets circulating in your child's blood stream is also decreased (this is called "thrombocytopenia") as a result of this condition. Research has shown that certain substances in the part of the blood known as plasma (the clear liquid part of the blood not including the red blood cells but holding blood clotting factors) can cause the organs to work poorly. The investigators would like to compare these blood responses in children with this condition, receiving a variety of different treatments, for multiple organ failure in other medical centers around the world. The investigators hope to enroll 80 patients into the study.
French Adult Primary Immune Thrombocytopenia
ThrombocytopeniaPrimary immune thrombocytopenia (ITP) is rare. First-line treatment is corticotherapy. Then, several second-line treatments (SLT) are available: splenectomy, off-label rituximab and thrombopoietin-receptor agonists since 2009. The compared efficacy and safety on clinical events in the long-term are unknown. The main objective of the FAITH study is to build the cohort of all treated adult persistent (≥3 months) primary ITP patients in France, to assess the benefit-to-risk ratio of SLT in real-life practice. Data source is the database of French Health Insurance System (SNIIRAM) which covers the entire French population. It collects demographic, chronic disease, hospitalization and drug dispensing data. All patients with ITP were extracted from 2009 to 2012, and then every year for 10 years. The investigator will build the cohort from raw data. Outcomes (death, hospitalization, drug dispensing) will be compared according to SLT, with controls from the general population and untreated patients.
