Pathogenesis of IgA Deficiency ‘In IgA-deficient patients, the common finding is a maturation defect in B cells to produce IgA’. ‘In IgA deficiency, B cells express IgA; however, they are of immature phenotype with the coexpression of IgM and IgD, and they cannot fully develop into IgA-secreting plasma cells’. [7]
IgG deficiency - IgG deficiency is a lack of IgG in the absence of other immunoglobulin deficiencies. IgG levels of 300–600 mg/dL show a mild to moderate reduction of IgG while levels below 200 mg/dl are classified as a severe deficiency. [6] Those with IgG deficiency often get chronic or reoccurring pyogenic respiratory tract infections. [7]
The IgA dimeric form is the most prevalent and, when it has bound the Secretory component, is also called secretory IgA (sIgA). sIgA is the main immunoglobulin found in mucous secretions, including tears, saliva, sweat, colostrum and secretions from the genitourinary tract, gastrointestinal tract, prostate and respiratory epithelium. It is also ...
The majority of CVID patients have normal B cell counts, suggesting the impaired antibody production is mainly a defect in the differentiation process of B cells into memory and plasma cells. There are also T cell abnormalities in CVID including counts, percentages, surface markers and function differences.
IgA has the most anodal mobility and typically migrates in the region between the beta and gamma zones also causing a beta/gamma fusion in patients with cirrhosis, respiratory infection, skin disease, or rheumatoid arthritis (increased IgA). Fibrinogen from plasma samples will be seen in the beta gamma region. Fibrinogen, a beta-2 protein, is ...
Among patients with Evans syndrome, the prevailing causes of death were bleeding, infections, and hematological cancer. [ 4 ] It has been observed that there is a risk of developing other autoimmune problems and hypogammaglobulinemia , [ 30 ] in one cohort 58% of children with Evans syndrome had CD4-/CD8- T cells which is a strong predictor for ...
It is characterized by variable reductions in serum immunoglobulin (IgG, IgM and/or IgA) levels which cause most ICF patients to succumb to infectious diseases before adulthood. ICF syndrome patients exhibit facial anomalies which include hypertelorism, low-set ears, epicanthal folds and macroglossia. [3]
IgA nephropathy (IgAN), also known as Berger's disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy) and the immune system; specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney.
