Filter by:Primary humoral immunodeficiency (PHID), such as common variable immunodefiency, are the most common symptomatic primary immunodeficiency in adults, in France. Patients are more prone to infections (particularly bacterial upper and lower respiratory tract infections), auto-immunity and atopic manifestations. Morbidity and mortality in PHID are mainly linked to the presence of bronchiectasis, which can lead to infections and to chronic respiratory failure. However, bronchiectasis in these patients can be asymptomatic for a long time. There is no known predictive factors to identify patients more susceptible to develop bronchiectasis and notably, there was no link between the number of previous infectious episodes and bronchiectasis. A marked IgM deficiency and switched memory B cell deficiency might be associated with bronchiectasis. Thoracic CT-scan is recommended at PHID diagnosis but there is no guideline for follow-up, thus leading to bronchiectasis being under-diagnosis or leading to delayed diagnosis
Primary immunodeficiencies (PID) are a heterogeneous group of diseases that occur as a result of disorders that affect the development, differentiation and/or function of various cells and building blocks in the immune system. Among the symptoms and complications of PID, pulmonary complications are very common and significantly increase the morbidity and mortality of the disease.
The main objective of this study is to generate diagnosis and therapeutic-decision tools through the identification of molecular causes of PIDs with autoimmunity/inflammation and the variability in disease outcome at the transcriptional level using a combination of omics signatures (transcriptomics, epigenomics, proteomics, metagenomics, metabolomics and lipidomics).
Background: The immune system is the part of the body that fights infection. Some people have immune deficiencies that cause skin rashes, make them get sick often with infections, or make it difficult for their skin to heal. Researchers want to learn more to better treat conditions that affect immune response. Objective: To learn about how the immune system and skin healing are related to each other. Eligibility: People ages 18-75 with primary immune deficiency, eczema, or psoriasis. Healthy volunteers are also needed. Design: Participants will be screened with a medical and medicine history and a physical exam. They may take a pregnancy test. Participants will discuss the medicines or supplements they take as well as skin products they use, such as soaps and lotions. Participants will have up to 4 skin biopsies taken from the forearm. A needle will inject an anesthetic into the skin where the biopsy will be done. A sharp tool that looks like a tiny cookie cutter will be used to remove a round plug of skin a bit smaller than the tip of a pencil. Participants will give at least 1 blood sample. Participants may have optional skin swab collection. A cotton swab will be used to swab the skin on the arm. Participants may have optional skin tape collection. A sticky strip of tape will be placed on the arm and then removed. Participants may give leftover samples taken as part of their regular medical care. Participation will last for about 4 days. Participants will have 2 visits that each last about 1 hour. They may be asked to repeat the study in the future.
The corona pandemic is a continuing global challenge due to Corona Virus 2019 (COVID-19). The purpose of the study is to confirm the accepted hypothesis from the recommendations of The European Society for Blood and Marrow Transplantation, that the vaccine for COVID-19 is safe and has good efficacy in immunocompromised patients after a bone marrow transplant from a donor / cellular therapy.
The purpose of the study is to determine whether biweekly (every 2 weeks) administration of Immune Globulin Subcutaneous (Human), 20% Caprylate/Chromatography Purified (IGSC 20%) produces a steady-state area under the concentration versus time curve (AUC) of total Immunoglobulin G (IgG) that is non-inferior to that produced by weekly administration of IGSC 20% in treatment-experienced participants with primary immunodeficiency (PI).
The purpose of this study is to demonstrate bioequivalence of IVIG-PEG with Gamunex-C (IVIG-C) at steady-state as determined by comparing total Immunoglobulin G (IgG) area under the concentration-time curve during the defined dosing interval ([AUC0-τ] either every 3 weeks [AUC0-21 days] or every 4 weeks [AUC0-28 days]) and maximum concentration in a dosing interval (Cmax) in participants diagnosed with primary humoral immunodeficiency (PI) currently receiving chronic IVIG replacement treatment.
Currently about 90 cases of infection in children are reported every year in pediatric intensive care, a disease considered to be the main cause of hospitalization of children. 16% of invasive pneumococcal infections are linked to a genetic abnormality in immunity. Herpetic encephalitis has become a model of genetic infectious disease, with new mutations identified in the TLR3 pathway. Severe infections are no longer the result of chance and can be the way to reveal a primary immune deficiency. In this context, the investigators propose to evaluate the incidence of hereditary immune deficiency after a systematic immunological screening in children admitted for a severe infection in pediatric intensive care unit (ICU).
Summary for SCGAM-03: Clinical phase III study to monitor the safety, tolerability and efficacy of subcutaneous human immunoglobulin (Octanorm) in patients with primary immunodeficiency diseases who have completed the SCGAM-01 trial. Summary for SCGAM-03 in Canada: Clinical phase III study to monitor the safety, tolerability and efficacy of subcutaneous human immunoglobulin (octanorm) in patients with primary immunodeficiency diseases, including (but not limited to) those who have completed the SCGAM-01 trial
1. study the pharmacokinetics of mini-pooled intravenous immunoglobulin( MP-IVIG) 2. Study the safety and efficacy of a newly developed preparation of MP-IVIG in children with primary immunodeficiency (PID) : - Adverse reaction of MP-IVIG(anaphylaxis and haemolysis)( no or mild or moderate) - Prevention of severe bacterial infection - Improvement of general health(weight gain and mentality) - Integration in to social live 3. Compare the efficacy of MP-IVIG to standard IVIG in children with primary immunodeficiency (PID).
