Filter by:The investigators aim to perform the first controlled randomized prospective study using ECZ in pediatric STEC-HUS. This is of great interest as there is still no efficient specific therapy in that potentially devastating disease. Furthermore, published data concerning the use of ECZ in STEC-HUS are controversial, reflecting statistical bias in retrospective or uncontrolled studies, thus emphasizing the need for prospective studies.
Autoimmune hemolytic anemia (AIHA) is an auto-immune disease mediated by specific antibodies targeting red blood cells. Its pathogenesis is not completely understood, and the role of T cells have been rarely studied. The aim of this study is to compare the frequency of circulating T cells, T cell polarization and functions, notably regulatory T cells, during warm AIHA by comparison to healthy controls. The role of treatments, such as steroids, will also be determined in patients with warm AIHA.
The aim of this study is to evaluate development of hemolysis and the variation in isokinetic muscle strength in two groups of patients with chronic inflammatory demyelinating polyneuropathy (CIDP) or multifocal motor neuropathy (MMN) 1. Patients shifted from 3- or 6-weekly treatment with intravenous immunoglobulin (IVIG) to weekly treatment with subcutanoeus immunoglobulin (SCIG) 2. Patients shifted from SCIG treatment with Subcuvia® or Hizentra® to Gammanorm®. Hypotheses - During treatment with IVIG blood hemoglobin will fluctuate with a decline due to infusion, whereas it will remain stable during SCIG treatment without fluctuation - Isokinetic muscle strength in affected muscle groups is more stable during treatment with SCIG than with IVIG - Blood hemoglobin and changes in muscle strength is comparable during Subcuvia® or Hizentra® and Gammanorm® treatment
The purpose of this study is to describe the range and incidence of symptoms, treatments, and complications related to pyruvate kinase deficiency (PKD). Eligible patients are those of all ages with known PKD or with a hemolytic anemia and a family member with PKD. The study will collect retrospective medical history, routine clinical care data, and quality of life measures at baseline and annually for patients with PKD.
In this study, we aim to identify risk factors for hemolysis in blood samples drawn in the ED.
The objective of this retrospective trial is to assess safety and efficacy of eculizumab in aHUS patients treated outside of an Alexion-sponsored controlled clinical trial.
Protocol is intended to characterize the overall safety and tolerability of eculizumab in this population.
This protocol is intended to formally collect data on the treatment of aHUS with eculizumab in Japanese patients.
Alloantibodies can lead to serious clinical consequences and logistic problems like obtaining properly and timely matched blood for the patients who do develop these antibodies. Prevention of such serious events is possible by extended matching and typing of donor's blood against the patient's for all the possible antigens, but this process is cumbersome and costly. Identifying a high risk group will be a feasible first target for advanced matching a big step forward, and the aim of the investigators study. The aim of the project is to examine the association between clinical, environmental and genetic characteristics of the recipient of erythrocyte transfusions and the risk or resistance to immunization against erythrocyte alloantigens that he/she was exposed to during that transfusion episode.
The Hemolytic Uremic Syndrome (HUS) in its typical form occurs after a food born infection with a shiga-toxin secreting bacteria, usually Escherichia coli of the O157H7 serotype. An outbreak of bloody diarrhea followed by HUS begun after a collective meal with 120 persons on June 8th, 2011 in Bègles, a city of Bordeaux urban area (CUB). At least 9 patients, 8 adults and 1 child have been involved in this HUS outbreak, E. coli of the O104:H4 serotype being demonstrated in most patients. This outbreak is remarkable by its preponderance in adults and women, its aggressiveness with multiorgan involvement , i.e. the kidneys, brain, liver, pancreas, and skin. Pathophysiology, prognosis, and treatment of typical HUS are poorly defined, particularly in adults who are usually not involved in typical E. coli O157H7 HUS. The aim of the present study is to gain knowledge on these different aspects of the HUS, including response to therapy.
