French Registry of Adult Patients With Immune Thrombocytopenia and Autoimmune Hemolytic Anemia
Immune ThrombocytopeniaAutoimmune Hemolytic AnemiaCARMEN is a national, real-world clinical registry of all adult patients with incident diagnosis of Immune thrombocytopenia (ITP) or Autoimmune Hemolytic anemia (AIHA) patients in France. It is aimed at describing ITP and AIHA clinical features, assessing the real-world risk-benefit ratio of treatments and adherence to guidelines for ITP and AIHA management.
Efficacy and Safety of TPO Receptor Agonists in the Treatment of Elderly ITP Patients
Primary Immune ThrombocytopeniaElderly ITP patients have many underlying diseases, hormone contraindications and many adverse reactions during the use of hormones. TPO-RAs are oral small-molecule non-peptide drugs. Retrospective studies have shown that they have good efficacy and high safety in elderly patients. Therefore, this study is a prospective trial to evaluate TPO-RAs as the first-choice drug for the treatment of elderly ITP patients with contraindications to hormones, aiming to improve the efficacy-risk ratio of elderly patients
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
Platelet-Directed Whole Blood Transfusion Strategy for Malaria
Severe MalariaThrombocytopeniaOpen-label randomized controlled trial to test the effectiveness of whole blood transfusion for improving survival in children with severe malaria complicated by thrombocytopenia.
PRTX-100-203 Open-Label, Dose Escalation Study in Adult Patients With ITP
Immune ThrombocytopeniaPre-clinical and clinical evaluations show that PRTX- 100 has biological activity that may lead to improved platelet levels where these are decreased due to immunological pathologies and that PRTX-100 has an acceptable safety profile. In vivo treatment with PRTX-100 has been shown to raise platelet counts in a mouse model of immune thrombocytopenia (ITP). The primary objective of the study is to assess the efficacy of PRTX-100 in terms of platelet response in patients with chronic/persistent ITP.
Prevention of Thrombocytopenia in Glioblastoma Patients
ThrombocytopeniaGlioblastomaChemotherapy used in the treatment of primitive tumors of the central nervous system has a particularly important platelet toxicity compared to chemotherapy used for treatment of other tumors. Chemotherapy postponed for toxicity is often due to thrombocytopenia (TP). The TP and/or the other anomalies of coagulation, which can be spontaneous (Rogers, 2004) or induced (Gerber, 2006) can have dramatic consequences: specifically neurological (intratumoral bleeding with particularly important neovascularization) with a functional aggravation and sometimes involvement of vital prognosis, digestive (Garcia-Rodiguez, 2001) in patients receiving long term treatment with corticoids (potential gastric toxicity). The encouraging results from the EORTC/NCIC trial by Stupp (median survival among patients with newly diagnosed glioblastoma is 14.6 months with an estimated 5-year survival of 9, 8%), has changed the standard of care of these patients (Stupp et al., 2009). Patients with newly diagnosed, histologically confirmed glioblastoma receive radiotherapy (2 Gy given 5 days per week for 6 weeks, for a total of 60 Gy) plus continuous daily Temozolomide (75 mg per square meter of body-surface area per day, 7 days per week from the first to the last day of radiotherapy), followed by six cycles of adjuvant Temozolomide (TMZ) (150 to 200 mg per square meter for 5 days during each 28-day cycle). The Stupp regimen is currently the treatment of reference for glioblastoma and is used as a basis in various clinical studies with new agents. This study aims to evaluate Romiplostim for the treatment of TP secondary to initial TMZ chemotherapy of glioblastomas.
Efficacy and Safety of Apixaban in the Treatment of Heparin Induced Thrombocytopenia (HIT)
Heparin-induced ThrombocytopeniaHeparin-induced Thrombocytopenia and ThrombosisThis research study is studying a drug as a possible treatment for heparin induced thrombocytopenia (HIT) or Heparin-induced Thrombocytopenia and Thrombosis (HITT). The drug involved in this study is apixaban.
Eltrombopag for Thrombocytopenia in Patients With Relapsed Multiple Myeloma
ThrombocytopeniaMultiple MyelomaEltrombopag is a compound that may help stimulate the production of platelets. This drug has been used in treatment of low platelet counts caused by a disorder called idiopathic thrombocytopenic purpura and information from those other research studies suggests that Eltrombopag may help to maintain platelet counts in patients with relapsed multiple myeloma in this research study. In this research study,the investigators are trying to determine if Eltrombopag is effective in maintaining platelet counts in patients who are being treated for relapsed multiple myeloma.
