Turkey Thrombotic Thrombocytopenic Purpura Disease Registry: National Multicenter Study
TTP - Thrombotic Thrombocytopenic Purpura21 hematology centers in Turkey will participate in this noninterventional observational study. The recruitment target is 960 cases. Patients will be followed-up at least 1 year or to the end of the study according to the physicians' discretion, or withdrawal of consent. Recruitment period will be 36 months. Data will be collected via electronic case report form. Since the study cohort does not include only newly diagnosed patients, all aTTP patients will be included to the study, previous treatments and diagnosis information data could also be collected from hospital records. Patients recruitment duration: 3 years (36 months) Patients follow-up duration: 1 year (12 months)
Construction of a Database for TTP
TTP - Thrombotic Thrombocytopenic PurpuraInformation about patients was collected by reviewing the Hitech case system and telephone and outpatient follow-up, and the case database was constructed by Epidata software. The sample size is expected to be 200 cases, the participating hospital is the First Affiliated Hospital of Soochow University, and the study time frame is from Oct 20, 2022, to Oct 20, 2027. The observation indexes of the study include the basic information of patients' age and gender and the clinical related data of thrombotic thrombocytopenic purpura.
Plasma microRNA Levels and Some Cytokines Expression in Patients With ITP Primary Immune Thrombocytopenic...
Primary Immune ThrombocytopeniaImmune thrombocytopenia (ITP) is an autoimmune disease characterized by low platelet counts with or without mucocutaneous bleeding (McMillan, 2007). Like the majority of autoimmune diseases, ITP is an organ-specific disease, and abnormalities in the regulation of the immune system have been shown to play an important role in the initiation and/or perpetuation of the disease (McKenzie et al.,2013). Still, immune thrombocytopenia (ITP) is a significant clinical problem due to chronicity, treatment cost, occurrence mainly in, young, and relatively poorer quality of life

The United Kingdom Thrombotic Thrombocytopenic Purpura Registry (UK TTP Registry)
TTP - Thrombotic Thrombocytopenic PurpuraThis is a UK (United Kingdom) based registry, involving all sites treating newly presenting Thrombotic Thrombocytopenic Purpura (TTP). From this registry, important epidemiological data will be obtained. Admission and remission samples will be collected. DNA will be collected and analysed from patients wishing to participate to determine if any link exists between mutations/polymorphisms and the risk of TTP. As part of NHS commissioning, we will be undertaking long term follow up, to understand the impact of acute TTP on morbidity and mortality.

Use of Vitamin D as An Adjuvant Treatment in Children With Chronic Idiopathic Thrombocytopenic Purpura...
Immune ThrombocytopeniaImmune thrombocytopenia is an autoimmune disease in which platelets are targeted by the host immune system. Platelet depletion occurs when autoantibodies targeting glycoproteins (αIIb-β3 and GPIb) found on the surface of platelets opsonize the cells, resulting in destruction by macrophages. These antibodies can also bind to megakaryocytes and prevent complete maturation, which results in lowered levels of platelet production Vitamin D (VD) or 1,25-dihydroxyvitamin D, may be a potent immunomodulator, and it may have potential therapeutic use in many autoimmune diseases In 1991, researchers found that the production of interleukin (IL)-6 and IL-2 in cell cultures were reduced by 1,25(OH)2D3 VD deficiency is very common in children with either newly diagnosed or chronic ITP form.Correlation between hypovitaminosis D and a higher incidence of infections and autoimmune diseases was reported as well Case-Control interventional study (over time each participant will be randomized to be enrolled in one of either study arms in a random sequence). To evaluate the efficacy of VD supplementation as an adjuvant therapy in chronic ITP children and its effect on platelet count and bleeding score. The participants will be - Children from 1 year to 18 years diagnosed with Chronic ITP with platelet count <100,000/microL. Patients groups will be: Patients of Chronic ITP aged from 1year till 18 years old . in this study will be divided into 2 groups ● Group A : All patients with VIT D insufficiency(The preferred level for 25(OH)D is now recommended by many experts to be >30 ng/ml) will receive supplementary Vitamin D3(NIVAGEN Vitamin D3 Cholecalciferol 50000 IU) oral once weekly for 3 months as adjuvant therapy in combination with their treatment for ITP. ● Group B : patients in this group have sufficient VIT D level and will be divided into 2 groups : Group 1 B :will receive their standard treatment for ITP with VIT D. Group 2 B :will receive their standard treatment for ITP without VIT D. Complete blood picture will be made at the beginning of study then monthly to evaluate the number of platelets that expected to increase after VD supplementation
Initial Treatment of Patients With Immune Thrombocytopenic Purpura
Immune Thrombocytopenic PurpuraThis study will compare treatment with 3 courses of high-dose dexamethasone versus treatment with prednisone, for patients recently diagnosed with immune thrombocytopenic purpura (ITP). The primary hypothesis is that patients treated with high-dose dexamethasone will obtain a more durable remission than patients treated with prednisone.

Evaluating the Effectiveness of Adding Rituximab to Standard Treatment for Thrombotic Thrombocytopenic...
Thrombotic Thrombocytopenic PurpuraThrombotic thrombocytopenic purpura (TTP) is a rare disorder that causes blood clots to form in blood vessels. The main treatment for TTP is plasma exchange, in which affected patients receive transfusions of plasma, the liquid part of blood, from healthy donors. This study will examine the effectiveness of an antibody, rituximab, in combination with plasma exchange, at improving the immune response in people with TTP and decreasing the recurrence of TTP.
