Filter by:The objective of this study is to describe a paediatric population presenting an acute idiopathic thrombocytopenic purpura (ITP) and their evolution during their therapy in the region Pays de la Loire. The study will particularly evaluate the quality of life of these patients and their parents. The secondary objectives are to identify the predictive factors of the complications, the repetitions and the chronicity of the ITP, to estimate the principal parameters of the economic cost of therapy of the children suffering from ITP according to the protocol of therapy, set up in the region Pays de la Loire and the constitution of a blood sample collection which allow a better understanding of the physiopathology of this disease. It is about a prospective, multicentric clinical epidemiologic study of a paediatric cohort. Patients: 100 children from 0 to 17,99 years suffering from a first discovered ITP. The patients are not included if they present a serious, intercurrent, stabilized chronic pathology or not likely to modify the quality of life of the child and if they present a pathology other than the thrombopenia bringing into play the vital prognosis within a time lower than one year. These patients will be followed for 6 months according to the diagnosis of their ITP. During the 6 months follow-up of each patient, the study will not carry out more consultations, nor more blood tests than the usual follow-up of a child suffering from ITP. On the other hand, in addition to the J0 questionnaire, it will be requested to the patient and to his family to fill in the questionnaires of quality of life and way of life during the consultations of J8, 1 month, 3 months and 6 months. A check-up of autoimmunity at 6 months will be carried out if the thrombopenia persists (this check-up is usual and not-specific to the study). At the time of the blood test for the control of the platelets at J0 and 6 months, an additional blood sample will be carried out: 5 ml are taken for the children of an age ≤ at 2 years, 10 ml from 2 to 4 years and 15 ml of blood for the children of an age > at 4 years. These blood samples are intended for the constitution of a blood sample collection. The protocol of therapy of the children suffering from ITP is homogeneous in all centers, this protocol being a consensus established by the network of Oncopaediatrics of the Pays de la Loire. The instituted treatment will be in function of the gravity of the ITP expressed in 4 stages: Stage I: Platelets > 20 gigas/L and absence of clinical signs. Stage II: Platelets > 10 gigas/L and hemorrhagic signs: haematomas, petechias or occasional epistaxis without repercussion on the daily life. Stage III: moderate. Platelets > 10.000/mm3 and epistaxis with gauze pluggings or mucous lesions. Stage IV: severe. Platelets ≤ 10.000/mm3 or fall of 2 grs/dl of haemoglobin with bleedings: epistaxis, melaena or haemorrhages requiring a blood transfusion or an hospitalization and important changes in the activities of the daily life. Stages I and II do not receive any treatment and benefit from a simple monitoring. Stages III benefit from either a corticosteroid treatment (Méthylprednisolone or Prednisone) at the dose of 4 mg/kg and per day in 2 intervals during 4 days (maximal dose of 100 mg/day) or a monitoring according to the appreciation of the clinician. Stages IV profit in first intention from a treatment by Méthylprednisolone or Prednisone at the dose of 4 mg/kg and per day in 2 intervals during 4 days (maximal dose of 100 mg/jour). The therapeutic attitude and the stadification belong to a regional consensus, established before the study, but each one can decide to apply a treatment according to the gravity of the clinical state of the child.
Bone marrow failure syndromes (BMFS) are rare disorders characterized by dysfunctional hematopoietic stem cells, which give rise to all red and white blood cells. The deficiency of blood cells, or cytopenia, caused by this malfunction leads to an assortment of diseases and disorders, all of which are characterized as BMFS. Because these diseases are rare, conducting research on them is difficult, and standards of treatment for most BMFS have yet to be developed. This study will collect clinical and laboratory data from people with BMFS to identify the characteristics and biological markers associated with these diseases over time. This information will assist doctors and researchers to develop better therapies and diagnostic tests that will help improve the management of BMFS and cytopenias.
The purpose of the study is to evaluate the efficacy of starting dose of AMG 531 as measured by platelet counts by cohort dose-escalation design.
The purpose is to evaluate safety and feasibility of the use of Rituximab as an adjunct to standard therapy (plasmapheresis + steroids) for patients with thrombotic thrombocytopenic purpura (TTP). This includes evaluating the rate and type of treatment failure.
This study is designed to investigate the safety of a single infusion of GMA161 in patients with idiopathic thrombocytopenic purpura, as well as, the way the drug enters and leaves the body. In addition, throughout the study, platelet counts and other blood cell numbers will be measured. NOTE: A decision was made to terminate this study in June 2008 due to low enrollment.
The goal of this study is to evaluate the clinical effectiveness of the rituximab at the adults with a chronic immune thrombocytopenic purpura (>=6 months of evolution) and severe (platelets <= 30x109/L) and candidate to a splenectomy. The objective is to obtain after a treatment by the rituximab a satisfactory response to one year, defined by a number of platelets higher than 50x109/L and at least 2 times superior with the persistent initial figure without treatment during one year after the end of the treatment.
The objective of this study is to determine if the safety and tolerability of Immune Globulin Intravenous (Human), 10% Caprylate/Chromatograph Purified (IGIV-C) is similar when infused at two different infusion rates.
The purpose of this study is to evaluate the efficacy, tolerability and safety of IgPro10 in the treatment of patients with chronic immune thrombocytopenic purpura (ITP). The main efficacy parameter is the proportion of patients responding to treatment by an increase of platelet count to ≥ 50 x 10^9/L.
The purpose of this study is to evaluate whether Immune Globulin Intravenous (Human), 10% TVR (Triple Virally Reduced) Solution is an effective and safe treatment in patients with chronic idiopathic thrombocytopenic purpura.
The purpose of this research study is to compare the efficacy and safety of higher doses of rituximab to a combination of standard doses of Rituxan + CVP (Cyclophosphamide, Vincristine, and Prednisone) in patients with chronic Idiopathic Thrombocytopenic Purpura (ITP who did not respond to or relapsed after standard doses of rituximab.
