Filter by:Rationale: Primary antibody deficiencies (PAD) encompass a group of rare heterogeneous diseases. The clinical presentation may vary widely, including infectious and autoimmune symptoms and increased risk of malignancy. Due to the rarity of the diseases and this wide array of symptoms there is often a delay in diagnosis, of up to 12 years on average1-4. Timely diagnosis of PAD reduces morbidity, mortality and health care costs as effective therapies are available. The currently available screening systems for the broader group of primary immunodeficiencies (PID) have been shown to have poor diagnostic performance5-10 and are time consuming. We have thus developed an algorithm to screen patient records in a primary care setting for risk factors specifically for PAD. Patients with a high risk may undergo a laboratory assessment and referral if necessary, thus reducing the diagnostic delay of PAD. The aim of the current study is to validate this algorithm. Objective: Main objective: to validate a screening algorithm for PAD in a primary care setting in the Netherlands. Study design: Mono-centre cohort study based on regular care data Study population: Primary care patients aged 12-70 years with the 100 highest scores based on our algorithm.
Patients receiving intravenous immunoglobulin (IVIG) therapy for primary immunodeficiency and neurologic conditions may experience adverse drug reactions (ADRs). The mechanism of the ADR is unknown. Currently, the standard practice for these patients is to change from IV to subcutaneous IG (SCIG) but because of the need of immunomodulation or patient preference, SCIG may not be an option. Data has shown that some levels of complement decrease from pre- to post-infusion of IVIG. This study is to determine if replacing this complement protein may ameliorate ADRs.
Endothelial dysfunction and insulin resistance play a key role in the onset and development of atherosclerosis, cardiovascular diseases, and diabetes. Data in mice models have recently demonstrated that circulating immunoglobulins G (IgG) could be involved in the process. Patients with common variable immunodeficiency (CVID), who are characterized by low circulating levels of IgG, might represent an ideal model to clarify the role played in vivo in humans by circulating IgG. Polyclonal IgG, obtained from multiple donors, given intravenously (IVIgG), are used to treat various immunodeficiencies and autoimmune diseases, including CVID. By using this disease and its treatment by IVIgG as a model, aim of the current study is to clarify whether IgG affect endothelial function and insulin sensitivity in humans in vivo and whether the action of IgG on the endothelium involves a direct interaction with the endothelial cells.
In this study, the investigators test 2 dose levels of thiotepa (5 mg/kg and 10 mg/kg) added to the backbone of targeted reduced dose IV busulfan, fludarabine and rabbit anti-thymocyte globulin (rATG) to determine the minimum effective dose required for reliable engraftment for subjects undergoing hematopoietic stem cell transplantation for non-malignant disease.
The purpose of this study is to analyse the phenotype in a sub-population of adults with severe primary immunodeficiency with lymphoproliferation and neutropenia and to decipher the possible pathways involved, especially under the hypothesis of a CTLA4/LRBA schema
This aim of this research project is to determine if low to moderate level exercise can have an impact on stress, fatigue, and quality of life for individuals diagnosed with a primary immunodeficiency disease. This 8-week study will compare participants engaging in a semi-customized, home exercise program (exercise intervention group) to participants performing normal activities (non-exercise control group). This study will track stress, fatigue, and quality of life in individuals with a diagnosis of primary immunodeficiency disease, using standardized questionnaires, journals, and interviews.
Background: People who have certain immune system diseases often need a procedure called allo HSCT. This is short for allogeneic hematopoietic stem cell transplant. This might cure people with these diseases. Many people who need allo HSCT need donors who are relatives with similar genes. But the disease may also affect those in the donor pool. This may mean there are fewer options for people with inherited diseases. Researchers want to collect data on how transplant candidates and their donors are found. Objective: To find out how genetic diseases and the ways they are inherited affect the breadth of options for allo HSCT donors. Eligibility: Records from studies that have already been done. These will be for people ages 4 and older who were evaluated for allo HSCT or to be donors. Design: Participants already signed a consent form for their records to be shared. Researchers will study the participant data. Data will be stored in an electronic system. Researchers will use passwords to protect the data.
This research is being done to construct a survey questionnaire, a quality of life tool, to determine the health, well-being, ability to perform daily activities, and physical, social and emotional functioning in participants with primary immunodeficiency disorders (PIDD). This quality of life (QOL) tool will help physicians understand the effects of PIDD on a person's health. These quality of life surveys are important tools for physicians to measure outcomes for satisfaction and effects of treatment.
This study was designed to explore CDZ173, a selective PI3Kδ inhibitor, in patients with genetically activated PI3Kδ, i.e., patients with Activated phosphoinositide 3-kinase delta syndrome/ p110δ-activating mutation causing senescent T cells, lymphadenopathy and immunodeficiency (APDS/PASLI). The study consisted of two parts: Part I was the open label part designed to establish the safety and pharmacokinetics of CDZ173 in the target population, as well as to select the optimal dose to be tested in Part II. Part II was designed to assess efficacy and safety of CDZ173 in the target population.
The primary objective was to determine the efficacy of Human Normal Immunoglobulin (Subgam®) given subcutaneously by weekly infusion to patients with primary antibody deficiency. The secondary objective was to determine the safety of Subgam® given subcutaneously by weekly infusion to patients with primary antibody deficiency.
