Allergy in Patients with Selective IgA Deficiency
Introduction: Selective immunoglobulin a deficiency (IgAD) is the most frequent of the primary antibody deficiencies. Patients with IgAD can be either symptomatic or asymptomatic. Symptomatic patients suffer from a wide range of manifestations including allergy, malignancy, and autoimmunity. The prevalence of allergic diseases is assumed to be increased in IgAD patients. In this study, we aimed to evaluate the frequency of allergic disorders in IgAD patients as well as a comparison between these patients and IgA deficient patients without allergy. Methods: The present cohort study included 166 IgAD patients who were diagnosed at the Research Center for immunodeficiencies in childrens medical Center. To compare clinical data and laboratory records, all IgAD patients were classified into two groups as follows: patients with allergic diseases and patients without allergic diseases. Results: Among 166 patients with IgA deficiency, allergy was seen in 33 patients (19.8%). In this study, respiratory tract

The Gut-gut Axis: Cohabitation of Celiac, Crohns Disease and IgA Deficiency
An adult patient with IgA deficiency, celiac and Crohns disease is described. In addition to the rare association, he developed an unusual proximal Crohns disease. Unbalanced microbiome, increased intestinal permeability, susceptibility to infections that might initiate post translational modification of naïve protein and the genetic background, are shared between the three entities. It is speculated that the IgA immune deficiency and its consequences are the early factors that set the stage for the progression of the other two diseases. Based on recent knowledge, special nutritional therapies should be considered, in addition to the gluten free diet.

The book was originated by the Scientific Group on Immunodeficiency convened by the World Health Organization, and includes contributions ...
glossary:iga deficiency [Lymphedema People]
Selective IgA Deficiency is the severe deficiency or total absence of the IgA class of immunoglobulins in the blood serum and secretions. There are five types (classes) of immunoglobulins or antibodies in the blood: IgG, IgA, IgM, IgD, and IgE. The immunoglobulin class present in the largest amount in blood is IgG, followed by IgM and IgA. IgD and IgE are present in very small amounts in the blood. Of these immunoglobulin classes, it is primarily IgM and IgG that protect the bloodstream, body tissues, and internal organs from infection. It is also important that the body is protected at surfaces that come in close contact with the environment. These sites are the mucosal surfaces: the mouth and nose, the throat, the airways within the lung, the gastrointestinal tract, the eyes, and the genitalia. The IgA antibodies (which are transported in secretions to mucosal surfaces) play a major role in protecting mucosal surfaces from infection. IgG, IgM and IgE antibodies are also found in secretions at ...

TTG antibodies come in both IgA-based and IgG-based assays, which are performed with enzyme-linked immunosorbent assay by using human recombinant/derived proteins. IgA TTG has high sensitivity and specificity of ~98% and is the endorsed serologic marker for evaluating CD.[3] It is well-known that IgA deficiency affects 2%-3% of CD patients and occurs in 1:131 patients tested for CD;[4] thus, IgA-based assays alone are not always reliable. To avoid missing IgA-deficient CD, a serologic cascade testing starting with serum IgA level can be performed, and if normal, an IgA TTG is adequate; however, if the IgA level is low or absent, IgG-based testing with deamidated gliadin peptide (DGP) and/or TTG could be added/substituted[5] (Figure 1). The accuracy of IgG TTG is poor (30%-70%) in IgA sufficiency, so this test in isolation should not be used for routine CD screening.[6]However, IgG TTG performs well with known IgA deficiency, with sensitivity and specificity approaching 95%.[2] ...

Screening for celiac disease is recommended for people who have associated symptoms, an associated condition or a family history of celiac disease.1 The most widely available test is the tissue transglutaminase IgA antibody test, which has an estimated sensitivity of 90%-96% and a specificity of 95%.5 Selective IgA deficiency, which occurs in 2%-3% of people with celiac disease, may cause a false-negative result. If antibody testing is negative and celiac disease is suspected, the IgA level should be measured.5 All adults with an abnormal screening result should undergo a small-bowel biopsy to confirm the diagnosis of celiac disease.5 A confirmatory biopsy may not be necessary in children with additional criteria.1 ...

Allogeneic stem cell transplantation is a high-risk procedure which has traditionally been reserved for the treatment of immediately life-threatening hematologic malignancies which have failed less intensive therapies. With advances in supportive care, conditioning regimens, and immune suppression, however, transplant outcomes have markedly improved.21 Consequently, it is increasingly acceptable to apply it to non-malignant disorders such as congenital or inherited immunodeficiency syndromes, hemoglobinopathies43 and autoimmune diseases.65 Stem cell transplantation is the only curative treatment in autoimmune diseases, as the non-malignant B-lymphocytes underlying many of these diseases are often difficult to eradicate with non-myeloablative chemotherapy. Through the myeloablative chemotherapy and stem cell rescue with the additional cell-mediated clearance provided by graft-versus-host effect, durable cure may be achieved. The presence of immunopathologies may predispose patients to ...

Biomedical Discovery Network - Microbiome Meetings
Various studies have shown that dietary, environmental, and host-derived factors have a strong effect on the makeup and action of this significant microbial organ (De Filippo et al., 2010; Maurice et al., 2013; Goodrich et al., 2014). This homeostatic role of IgA in regulating commensal bacteria was lately confirmed in people using IgA deficiency (Fadlallah et al., 2018). In reality, a substantial portion of commensal bacteria has been proven to be coated with IgA and stably maintained in homeostatic conditions (van der Waaij et al., 1996). More recently, we demonstrated that diversification and choice of IgA repertoires at a T-cell-dependent manner in germinal centres of the Peyers patches contribute to improving the diversity and stability of both gut-resident species (Kawamoto et al., 2014). Additionally, T-independent pathways, likely originating from the lamina propria, have already been shown to contribute to the generation of an IgA repertoire thats polyreactive into a wide swathe of ...

I have been to my primary care physician, the emergency clinic, and an immunologist/allergist. I have had lots of diagnoses over the years, but have had terrible blistering rashes for the last two years that were initially diagnosed as MRSA (came back negative) and then as contact dermatitis. My doctors have given up on me and simply settled for extremely sensitive skin, which is not a satisfactory answer. I scheduled an appointment with a dermapathologist, but she cannot see me until December and I am so miserable now that I cannot even walk without extreme pain. A friend who has celiac recommended I look into it and I believe this is my answer. I left a message for my doctor requesting a scrip for dapsone to see if that will provide me any relief. I have had a negative blood test for celiac, but I have IgA deficiency, which increases my risk and the symptoms I have been suffering for years that have been diagnosed as one thing or another fit to a T. So what now? These doctors have failed me. ...

Screening of functional and positional candidate genes in families with common variable immunodeficiency | BMC Immunology |...
Common variable immunodeficiency (CVID) is the most prevalent symptomatic primary immunodeficiency in adults. CVID clinically presents with a history of recurrent infections at mucous membranes which is the consequence of a marked hypogammaglobulinemia [1]. The clinical course of CVID is complicated by a plethora of systemic immunopathology including autoimmunity, lymphoproliferation, malignancy and sarcoid-like granulomas.. CVID affects males and females equally and usually manifests in the second or third decade of life. A second peak of onset exists in childhood between the ages of 2 and 5 years [2, 3]. The prevalence of CVID in the Western hemisphere is estimated to be approximately 1: 25.000 [1, 4].. The majority of CVID cases are sporadic, while approximately 10 to 20% of CVID cases show at least one additional family member affected either by CVID or selective IgA deficiency (sIgAD) [5, 6]. Most multiplex CVID families show an autosomal dominant mode of inheritance but about 20% present ...
Altered Serum Cytokine Signature in Common Variable Immunodeficiency
2014, Springer Science+Business Media New York. Purpose: Common variable immunodeficiency (CVID) is the most frequent form of primary symptomatic hypogammaglobulinemia. CVID patients display a number of abnormalities in lymphocyte subpopulations including chronic T-cell activation and decreased numbers of circulating CD4+ T cells and NK cells. We and others have recently shown that CVID is associated with increased concentration of soluble CD14 (sCD14) and other factors indicating limited microbial translocation.Methods: To address the mechanisms of chronic immune activation in CVID, we performed a detailed analysis of cytokine serum levels in 36 patients with CVID, 52 patients with selective IgA deficiency (IgAD), and 56 healthy volunteers.Results: We show that CVID is associated with elevated serum levels of CXCL-10/IP-10, IL-1R antagonist, TNF-α, IL-10, IL-12 (p40), CCL-2/MCP-1, G-CSF, and CCL-11/eotaxin. The detected cytokine signature is consistent with an ongoing activation of cells of ...

There are two types of immunodeficiency diseases; primary and secondary.. Primary immune deficiency, caused by a genetic problem in the bodys defense system, is when the bodys immune defense system is missing a part or does not work correctly. Over 150 different primary immune deficiency diseases are known today with some occurring with greater frequency (selective IgA deficiency) while others are extremely rare (ADA deficiency). If a primary immune deficiency is not treated, it can cause serious illness and life-threatening infections. Present day, thanks to enhanced technology, doctors can recognize primary immune deficiency signs even earlier in order people can live close to normal lives with treatment. Previously, treatment options were limited and life expectancy was shorter for some of these individuals.. Secondary immune deficiency disease is when the bodys defense system is changed due to an external factor outside the body. Some examples include dialysis, burns, chemotherapy, ...

The human MHC spans ∼4 megabases (Mb)3 of DNA in the chromosome band 6p21.3. Of this, the central ∼1.1 Mb is termed the class III region (1). It is becoming increasingly apparent that, in common with the MHC class I and II regions (for review see 2), the class III region contains many genes that encode proteins involved in immune and inflammatory responses (3). These include the C2, C4, and factor B components of the complement system, members of the 70-kDa heat shock protein family, the cytokines TNF, lymphotoxin α (LTα) and LTβ (3), and the inflammatory mediator lysophosphatidic acid acyltransferase (4). Furthermore, genetic studies have indicated that genes within the MHC contribute to immune-related diseases, such as insulin-dependent diabetes mellitus (IDDM), rheumatoid arthritis, ankylosing spondylitis, myasthenia gravis, common variable immunodeficiency (CVID), and IgA deficiency (5, 6). Strong associations have been found between these diseases and alleles of genes in the MHC ...
Pharos : Target Details - ENSP00000364855
Involved in DNA mismatch repair and meiotic recombination processes. Facilitates crossovers between homologs during meiosis (By similarity). This gene encodes a member of the mutS family of proteins that are involved in DNA mismatch repair and meiotic recombination. This protein is similar to a Saccharomyces cerevisiae protein that participates in segregation fidelity and crossing-over events during meiosis. This protein plays a role in promoting ionizing radiation-induced apoptosis. This protein forms hetero-oligomers with another member of this family, mutS homolog 4. Polymorphisms in this gene have been linked to various human diseases, including IgA deficiency, common variable immunodeficiency, and premature ovarian failure. Alternative splicing results multiple transcript variants. Read-through transcription also exists between this gene and the downstream chromosome 6 open reading frame 26 (C6orf26) gene.

What If Your Immune System Stops Working? - BingoPublishingsest
Immunodeficiency disorders happen when one or more components of your immune system are missing or when the system is not working as supposed to be. Defects in ones immune system can be congenital or acquired. Either way, having problems with the immune system permits harmful microorganisms to easily penetrate the bodys defenses and make anyone suffer various diseases.. Congenital Or Primary Type. If you are born with deficiencies in your immune system, you are said to be suffering from primary immunodeficiency. If you have the primary type of this disease, you may not be able to enjoy life like other people do.

Particle Gel Immuno Assay (ID-PaGIA) zum Nachweis von anti-IgA Antikörpern
Anti-IgA antibodies are thought to be responsible for non-hemolytic transfusion reactions in one in 17,000 to one in 770,000 number of cases. This incidence is mainly supported by case reports. Despite their relative frequency of one in 18 to one in 1,250, since their discovery approximately forty years ago, the true significance of these antibodies has not yet been determined. Several specificities of these antibodies resulting in different reaction patterns make diagnosis and categorization difficult. Until recently, the lack of a fast and reliable laboratory test was a drawback. This test needed to be easily performed, fast, accurate, reproducible and accessible to many practitioners in many laboratories. The Passive Hemagglutination Assay (PHA), developed in the late 1960s, is neither precise nor reliable but easy to perform and therefore has been the mainstay in diagnosis of anti-IgA. While newer methods, such as Radio Immuno Assay (RIA) and Enzyme Linked Immunosorbent Assay (ELISA), are ...

Primary Immunodeficiencies - American Family Physician
Primary immunodeficiencies include a variety of disorders that render patients more susceptible to infections. If left untreated, these infections may be fatal. The disorders constitute a spectrum of more than 80 innate defects in the bodys immune system. Primary immunodeficiencies generally are considered to be relatively uncommon. There may be as many as 500,000 cases in the United States, of which about 50,000 cases are diagnosed each year. Common primary immunodeficiencies include disorders of humoral immunity (affecting B-cell differentiation or antibody production), T-cell defects and combined B- and T-cell defects, phagocytic disorders, and complement deficiencies. Major indications of these disorders include multiple infections despite aggressive treatment, infections with unusual or opportunistic organisms, failure to thrive or poor growth, and a positive family history. Early recognition and diagnosis can alter the course of primary immunodeficiencies significantly and have a positive effect

Common variable immunodeficiency (CVID), the most common primary immunodeficiency seen in clinical practice, represents a heterogeneous group of syndromes characterised serologically by low antibody levels and clinically by recurrent respiratory tract infections, granulomatous inflammation and autoimmunity. The choice of IRT administration modalities includes subcutaneous (SC), facilitated subcutaneous (fSC) and intravenous (IV) routes. The different routes are thought to be equivalent in their therapeutic effects. However, there are clear pharmacokinetic differences between the delivery methods. It is unclear whether these differences have a clinically relevant impact on inflammation. This is an important issue as such differences might have an impact on administration modality. We will investigate the effects on systemic inflammation and immune activation of different modalities of Immunoglobulin Replacement Therapy in Common Variable Immune Deficiency..

N2 - Increased proportions of naive B cell subset and B cells defined as CD27negCD21negCD38neg are frequently found in patients with common variable immunodeficiency (CVID) syndrome. Current methods of polychromatic flow cytometry and PCR-based detection of k deletion excision circles allow for fine definitions and replication history mapping of infrequent B cell subsets. We have analyzed B cells from 48 patients with CVID and 49 healthy controls to examine phenotype, frequency, and proliferation history of naive B cell subsets. Consistent with previous studies, we have described two groups of patients with normal (CVID 21norm) or increased (CVID 21lo) proportions of CD27negCD21negCD38neg B cells. Upon further analyses, we found two discrete subpopulations of this subset based on the expression of CD24. The B cell subsets showed a markedly increased proliferation in CVID 21lo patients as compared with healthy controls, suggesting developmental arrest rather than increased bone marrow output. ...

PI3Kδ and primary immunodeficiencies - White Rose Research Online
Primary immunodeficiencies are inherited disorders of the immune system, often caused by the mutation of genes required for lymphocyte development and activation. Recently, several studies have identified gain-of-function mutations in the phosphoinositide 3-kinase (PI3K) genes PIK3CD (which encodes p110δ) and PIK3R1 (which encodes p85α) that cause a combined immunodeficiency syndrome, referred to as activated PI3Kδ syndrome (APDS; also known as p110δ-activating mutation causing senescent T cells, lymphadenopathy and immunodeficiency (PASLI)). Paradoxically, both loss-of-function and gain-of-function mutations that affect these genes lead to immunosuppression, albeit via different mechanisms. Here, we review the roles of PI3Kδ in adaptive immunity, describe the clinical manifestations and mechanisms of disease in APDS and highlight new insights into PI3Kδ gleaned from these patients, as well as implications of these findings for clinical therapy.. ...
