Filter by:Primary 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.
It seems reasonable to assume that patients who present significant bleeding symptoms may have different quality of platelets than those without bleeding. This question was addressed in a study that examined platelet function in adult ITP patients, which try to determine whether this correlated with bleeding risk. Previous reports have suggested that measuring platelet function may help define patients at highest risk of bleeding. In addition, Middelburg and colleagues corrected platelet function for quartile of platelet count, using ＜32×10^9/L as the lowest cohort and ＞132×10^9/L as the top quartile. They demonstrated that increased platelet reactivity (as measured by flow cytometry) was associated with decreased risk of bleeding but particularly for those patients with the lowest platelet counts. Further studies in a larger cohort are needed to confirm this correlation. Our study aimed at standardizing a prediction model to evaluate the bleeding risk of adult ITP patients with the use of platelet function tests.
Immune thrombocytopenia (ITP) is a heterogeneous disorder with variable clinical symptomsHealth related quality of life (HRQoL) could be considered in ITP, as in numerous chronic diseases, as a method to provide information about the effects of medical interventions. Symptoms of ITP, such as spontaneous bruising, menorrhagia, mucosal bleeding and prolonged bleeding with injury, may significantly affect HRQoL in ITP subjects. Treatments for chronic ITP can also be associated with substantial side effects. Restoring and/or maintaining quality of life should be an important goal of treatment. We conducted a real-world multicenter study using SF-36 and ITP-PAQ questionnaires to assess the HRQoL in patients with ITP in the real world, and analyze the influencing factors of HRQoL so as to provide a sufficient basis for clinical decision making.
Background: Antithrombotic therapy in the context of treatment related thrombocytopenia (i.e. low levels of platelets) is not uncommon. Guidelines are based upon a paucity of retrospective data and focus on the scenario of cancer associated venous thrombosis and low molecular weight heparin treatment. Even less is known regarding direct oral anticoagulants, antiplatelet therapy, or anticoagulation prescribed for other indications. Aims: The study aims are to evaluate how physicians manage anticoagulant and antiplatelet medication in patients with hematological malignancy and thrombocytopenia, and to assess the frequency of bleeding and thrombosis. Additional aims are to assess how management changes affect drug activity and blood clotting (coagulation), and to evaluate the use of platelet transfusions. Design: The investigators plan a multinational prospective registry of patients admitted to the inpatient hematology department or outpatient clinic at one of the study centers. Patients with hematological malignancies, platelets below 50 X 109/L, and anticoagulant and/or antiplatelet medication will be studied. Patients will be enrolled when the combination of antiplatelet/anticoagulant medication and thrombocytopenia is first detected. Patients will be followed until 30 days after the baseline study visit (which occurs 30 days after enrollment or when platelets < 50*109/L, whichever come first) or death. Patients will be indexed at the time of baseline visit. Patients will be excluded from study analysis if one of the following events occurs before study index: Withdrawal of consent, death, clinically-relevant non-major bleeding or the composite primary outcome. Risk factors for bleeding and thrombosis will be recorded at baseline. Parameters from routine blood tests will be recorded throughout the study. During the study major bleeding events and thrombosis will be recorded. Investigational blood tests assessing coagulation and drug activity will be drawn at baseline (=study index). Throughout the study all management decisions regarding antithrombotic therapy, including platelet and red blood cell transfusion, will be recorded. This is an observational study and management will be solely at the discretion of the physician. Analysis: The investigators will first look at the frequency of either bleeding or thrombosis according to the type of management strategy and evaluate the platelet threshold at which a given management strategy is employed. At the next stage, in selected subgroups, the optimal management strategy with respect to bleeding/thrombotic risk, will be determined.
The purpose of this study is to determine the efficacy of H. pylori eradication for the treatment of chronic or persistent immune thrombocytopenic purpura (ITP) patients with moderate thrombocytopenia. This is a multi-center, open label, prospective randomized phase IIl study.
Thrombocytopenia refers to a reduction in platelet count to (<150 × 109/L). Immune thrombocytopenic purpura is an acquired autoimmune disorder defined by isolated thrombocytopenia and the exclusion of other causes of thrombocytopenia
Autoimmune thrombocytopenic purpura is an immunological disorder characterized by increased platelet destruction due to presence of anti-platelet antibodies. Hepatitis C virus infection, which is one of the most common chronic viral infections worldwide, may cause secondary chronic immune thrombocytopenic purpura. It seemed to play a pathogenic role in autoimmune thrombocytopenic purpura. Moreover, the successful response (negative hepatitis C virus - ribonucleic acid) to tapered steroids and antiviral therapy was useful to revert thrombocytopenia

Multi-Center Single Arm Trial to Determine The Effectiveness of Warfarin Therapy Duration For Heparin-Induced Thrombocytopenia (HIT)
Primary immune thrombocytopenia (ITP) is an acquired autoimmune bleeding disorder, accounting for about 1/3 of clinical hemorrhagic diseases. Loss of immune tolerance leading to increased platelet destruction and decreased platelet production is the main pathogenesis of ITP. Dysbiosis of the gut microbiota was found in many autoimmune diseases like rheumatic arthritis(RA),inflammatory bowel disease(IBD),multiple sclerosis and probiotic treatment or fecal microbiota transplantation(FMT) which can regulate the gut microbiota has good clinical efficacy in those disorders. One ITP patient with ulcerative colitis(UC) was treated with FMT and got progressive but significant increase in platelet level and lasted for several years.
