Filter by:Current diagnostic criteria for Immune ThrombocytoPenia (ITP) are mainly based on the presence of low numbers of platelets, excluding other multiple causes of thrombocytopenia, including immunodeficiencies, constitutional or acquired thrombocytopenia, hypersplenism and clonal hematological disorders such as MDS, disorders lymphoproliferative and acute myeloid leukemia (AML), among others. The analysis complementary tests for the diagnosis of ITP include studies basic systematic hematology, together with autoimmune assays and microbiological tests, while the evaluation of bone marrow is limited to elderly patients and/or patients resistant to treatment. Previous research has described the development of Myelodysplastic Syndrome (MDS) in patients with a previous diagnosis of ITP, and even the presence of MDS associated with genetic background. Therefore, it is conceivable fact that a percentage of cases with clinical signs of ITP in the moment of appearance may actually correspond to the first stages of MDS development in which bone marrow cells are not systematically evaluated in the initial presentation. The anomalous immunophenotypic patterns between multiple compartments of bone marrow cells and peripherally blood (PB) platelets have been characterized through flow cytometry. The flow cytometry currently represents an important complementary tool for diagnosis of MDS that has shown great effectiveness and applicability in the differential diagnosis of non-clonal cytopenias against early MDS and for the detection of stages prior to MDS. Besides, the flow cytometry has made it possible to detect the presence of coexisting features related to MDS in patients with other malignancies hematologic conditions such as multiple myeloma, AML, and lymphocytic leukemia chronic. Therefore, the immunophenotypic analysis of the cells of the bone marrow of patients with ITP at the time of appearance would help to identify the cases that underlie clonal hematopoiesis MDS type. In the present study it is planned a broad characterization immunophenotyping of multiple compartments of bone marrow cells and PB platelets from patients with recently diagnosed ITP and investigate their morphological antecedents, in order to identify those patients who show compatible clonal hematopoietic patterns with MDS evident (or at risk of development), as candidates to receive most appropriate therapeutic methods.
The project was undertaking by Qilu Hospital of Shandong University in China. In order to compare the efficacy, safety and response duration of different dose of rituximab in patients primary immune thrombocytopenia(pITP).
Hydroxychloroquine has been reported to have a clinically significant effect on the platelet count in systemic lupus thrombocytopenia. Its action may be due to its immune modulator effect. Immune thrombocytopenia (ITP) is known as an immune-mediated acquired disease characterized by transient or persistent decrease of the platelet count. However, refractory ITP is lacking of effective treatments and the efficacy of decitabine in ITP remains poorly understood. Data from this study may provide some idea of Hydroxychloroquine in the treatment of ITP in comparison to other lines of treatment as detected by the standardized definitions.
The main purpose of this study is to assess the efficacy and safety of LIV-GAMMA SN Inj. in adult subjects with ITP. The primary objective of this study is to determine the responder rate. A response is defined as a platelet count of ≥30×10^9/L and at least a 2 fold increase of the baseline, confirmed on at least 2 separate occasions at least 7 days apart without bleeding. The secondary objectives are to evaluate the further efficacy assessments including duration of response, and the safety of LIV-GAMMA SN Inj.
This is a study of two treatment pathways [Standard steroid treatment versus combined steroid and Mycophenolate (MMF)] for subjects with newly diagnosed Immune Thrombocytopenia (ITP). ITP is an illness that causes bruising and bleeding due to a low platelet count (blood cells essential for normal clotting). Patients are first given high dose steroids but most suffer side effects (e.g. difficulty sleeping, weight gain, moods swings, high blood pressure and diabetes). In addition, the majority of patients become ill again when the steroids are stopped - only about 20% stay well long term. ITP is relatively rare, non-cancerous in nature and the rare impact on survival of ITP have prevented it from being a priority for research funding, with first line treatment being unsatisfactory and unchallenged for decades. This underestimates the profound adverse impact an ITP diagnosis and its treatment has on individual patients, many of whom are young. MMF is often used as the next stage treatment for ITP and it works well. However, it can take up to 2 months to work during which patients continue to be at risk of bleeding, bruising, fatigue and usually need more steroids which they find intolerable. They are required to come to hospital for weekly blood tests and for many this impacts on work. We want to find out whether it would benefit more patients if everyone takes MMF at diagnosis instead of current practice (waiting for the illness to come back). We plan to test this by comparing the current way we treat patients to a new way with patients given MMF right at the start of their treatment. 120 patients from 20 different hospitals will be asked to take part and half will be randomly chosen for the new pathway.
Previous studies have shown that increase level of BAFF could promote the settlement of long-lived plasma cells in the spleen of ITP patients treated with anti-CD20. This single-center prospective pilot study, currently in phase IIa, will evaluate the efficacy of a rituximab and belimumab sequential combination treatment. Investigators plan to include 15 patients with persistent ITP over a 24-month inclusion period. Each patient will be followed for 1 year
The objective is to evaluate the efficacy and safety of romiplostim for injection in adlut subjects with persistent or chronic primary immune thrombocytopenia (ITP).
The main purpose of this study is to assess the efficacy and safety of BT595 in adult subjects with chronic ITP. The primary objective of this study is to determine the rate of subjects with a response. A response is defined as a platelet count of ≥30×10^9/L and at least a 2 fold increase of the baseline count, confirmed on at least 2 separate occasions at least 7 days apart, and the absence of bleeding. The secondary objectives of this study, in addition to further efficacy assessments, are to evaluate the safety of BT595.
The study aims to investigate immunomodulatory effects of thrombopoietin-receptor Agonist (TPO-RA) in patients with primary ITP, who failed first-line therapy or who became intolerant to it. It is hypothesized that the early phase of this autoimmune disease may exhibit a stronger immunomodulatory potential in response to a stimulus, such as romiplostim. Such a process may subsequently be capable to induce regulatory mechanisms or tolerance. Romiplostim (a thrombopoietin-receptor agonist, TPO-RA) will be administered subcutaneously once weekly over 22 weeks with a starting dose of 1mcg/kg body weight. The dose will be adjusted based on platelet counts as described in the summary of Product Characteristics (SmPC).
The project was undertaking by Qilu Hospital of Shandong University in China. In order to report the efficacy and safety of caffeic acid tablets combining with high-dose dexamethasone for the treatment of adults with newly-diagnosed primary immune thrombocytopenia (ITP).
