OBS'CEREVANCE: French Cohort of Pediatric Autoimmune Cytopenia

OBS'CEREVANCE
Start date: September 1, 2010
Phase:
Study type: Observational [Patient Registry]

From 2004, OBS'CEREVANCE is a national real-world prospective clinical cohort of patients with auto-immune cytopenia of pediatric-onset : Immune thrombocytopenia (ITP), Autoimmune Hemolytic anemia (AIHA), or Evans syndrome (all bi or tri cytopenias). Thanks to the collaboration of the 30 French pediatric hematologic centers, this cohort supports all of the Rare Disease Centre CEREVANCE (Centre de Référence National des Cytopénies Auto-Immunes de l'Enfant) missions for care, education and research. Specifically, this original unbiased database allows to describe the long-term health of adult patients, to identify the heterogenous genetic underlying pathophysiologic contexts, and to study the benefit-risk balance of treatments, including the growing development of targeted therapies.

NCT ID: NCT05931718 Recruiting - Clinical trials for Myelodysplastic Syndromes

Prospective Evaluation of Diagnosis and Treatment of Patients With Autoimmune Cytopenias Including Autoimmune Hemolytic Anemia, Immune Thrombocytopenia, and Chronic Idiopathic/Autoimmune Neutropenia

AIHA ITP CIN
Start date: June 1, 2021
Phase:
Study type: Observational

The goal of this observational study is to characterize the diagnostic and therapeutic management of autoimmune cytopenias including autoimmune hemolytic anemia, immune thrombocytopenia, and chronic idiopathic/autoimmune neutropenia. The main aims to answer are: - evaluation of traditional and novel diagnostic tools including immunohematology, cytokine essays, bone marrow studies, molecular findings, and fecal microbiome. - evaluation of type and sequence of the therapies administered, the response rates, and the adverse events. - evaluation of clinical and laboratory (immunologic, molecular, and morphologic) predictors of outcome. - evolution of autoimmune cytopenias into myelodysplastic syndromes. - a subgroup of patients with myelodysplastic syndromes will be included to evaluate the presence of immunologic events, autoimmune activation, and red cell metabolism. Participants will receive a clinical/laboratory diagnostic workup as per current clinical practice. Furthermore They will be sampled at baseline (peripheral blood and feces for microbiome) and followed up for at least 3 years to evaluate their clinical course, therapeutic management and outcome.

Efficacy of Prolonged Anticoagulation for Primary Prevention of Venous Thromboembolic Disease in Autoimmune Hemolytic Anemia: a Prospective, Phase II, Randomized, Multicenter Study

API-AHAI
Start date: February 3, 2022
Phase: Phase 2
Study type: Interventional

Autoimmune hemolytic anemia (AIHA) is a rare autoimmune disease (incidence <1/100,000 population) responsible for the destruction of red blood cells by the host immune system, notably through the action of autoantibodies. Apart from complications related to anemia, the occurrence of venous thromboembolism (VTE) in this population is frequent, estimated at 20-27%. The risk of VTE is highest during the period of hemolysis, especially during the first 3 months after the diagnosis of AIHA. This risk is 7.5 [4.7; 12.0] times greater than in the general population. No clinical predictive factor for VTE was identified and the usual factors (cancer, previous VTE, bed rest >3 days, surgery, age >70 years, heart or respiratory failure, myocardial infarction, stroke, obesity, hormone replacement therapy) were not considered. Several biological risk factors have been suggested (depth of anemia, bilirubin level, leukocyte count, antiphospholipid antibodies) but have not been confirmed in other studies. AIHA is therefore a risk factor for VTE in its own right, and the National Diagnostic and Care Protocol (NDCP) recommends the implementation of VTE prevention during acute hemolysis (Grade C). However, the value of this prophylaxis has never been prospectively evaluated and its duration is empirical. In practice, low-molecular-weight heparin (LMWH) is generally used during "flare-ups" of AIHA (diagnosis and relapse) in hospitalized patients, but is rarely continued beyond the hospital phase when VTE also occurs in ambulatory patients. Thus, we hypothesize that prolonged preventive anticoagulation during the 12-week risk period following diagnosis or relapse of AIHA could decrease the incidence of VTE. In orthopedic surgery, this strategy has been proven to decrease VTE from 50% to 10-15%. In certain high-risk medical situations, prolonged prophylaxis with apixaban has been shown to decrease the occurrence of VTE from 10.2% to 4.2% in solid cancers4 and from 4-11% to 2% in myeloma.

NCT ID: NCT04024202 Recruiting - Clinical trials for Autoimmune Hemolytic Anemia

Data Registry of Auto Immune Hemolytic Anemia

DRAIHA
Start date: July 12, 2019
Phase:
Study type: Observational

In autoimmune hemolytic anemia (AIHA) auto-antibodies directed against red blood cells (RBCs) lead to increased RBC clearance (hemolysis). This can result in a potentially life-threatening anemia. AIHA is a rare disease with an incidence of 1-3 per 100,000 individuals. An unsolved difficulty in diagnosis of AIHA is the laboratory test accuracy. The current 'golden standard' for AIHA is the direct antiglobulin test (DAT). The DAT detects autoantibody- and/or complement-opsonized RBCs. The DAT has insufficient test characteristics since it remains falsely negative in approximate 5-10% of patients with AIHA, whereas a falsely positive DAT can be found in 8% of hospitalized individuals. Also apparently healthy blood donors can have a positive DAT. The consequences of DAT positivity are not well known and may point to early, asymptomatic disease, or to another disease associated with formation of RBC autoantibodies, such as a malignancy or (systemic) autoimmune disease. Currently, there are no guidelines to follow-up DAT positive donors. A second unsolved difficulty is the choice of treatment in AIHA. Hemolysis can be stopped or at least attenuated with corticosteroids, aiming to inhibit autoantibody production and/or RBC destruction. Many patients do not respond adequately to corticosteroid treatment or develop severe side effects. Currently, it is advised to avoid RBC transfusions since these may lead to aggravation of hemolysis and RBC alloantibody formation. But in case symptomatic anemia occurs, RBC transfusions need to be given. An evidence-based transfusion strategy for AIHA patients is needed to warrant safe transfusion in this complex patient group. To design optimal diagnostic testing and (supportive) treatment algorithms, the investigators will study a group well-characterized patients with AIHA and blood donors without AIHA, via a prospective centralized clinical data collection and evaluation of new laboratory tests. With this data the knowledge of the AIHA pathophysiology and to evaluate diagnostic testing in correlation with clinical features and treatment outcome can be improved.

NCT ID: NCT04005638 Recruiting - Clinical trials for Immune Thrombocytopenia

Biological Bank for the Patients Followed in a Constitutive Reference Center for Autoimmune Cytopenia

BIOCAI
Start date: February 2, 2019
Phase:
Study type: Observational

The Internal Medicine Department of Haut-Lévêque Hospital (Pr E LAZARO, Pr JL PELLEGRIN, Pr JF VIALLARD) was accredited in 2017 by the Ministry of Health as a Constitutive Reference Center for Autoimmune Cytopenia. The investigators wish to launch new research projects in autoimmune cytopenia and propose a translational and fundamental research based on collaboration between the clinical department, the biological resource center and the CNRS and INSERM research units ("Bedside to the Bench Strategy"). Thus, in the perspective of future research work, it seems imperative to set up a biological bank for the patients followed in our Reference Center.

NCT ID: NCT03918265 Recruiting - Clinical trials for Autoimmune Hemolytic Anemia

Tacrolimus Treatment for Refractory Autoimmune Cytopenia

Start date: May 4, 2019
Phase: Phase 4
Study type: Interventional

Autoimmune cytopenia, including autoimmune hemolytic anemia (AIHA), pure red cell aplasia (PRCA), Evans syndrome (ES), usually has good responses to steroids therapies as first line, but there is a considerable percentage of patients who relapse, become refractory or dependent on steroids to maintain an acceptable level of hemoglobin or platelets. The effects of the second line therapy are also not satisfactory and sometimes not available. The investigators aim to explore the efficacy and side-effect of tacrolimus for refractory autoimmune cytopenia.
