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 most common antibody isotype involved in warm antibody AIHA is IgG, though sometimes IgA is found. The IgG antibodies attach to a red blood cell, leaving their F C portion exposed with maximal reactivity at 37 °C (versus cold antibody induced hemolytic anemia whose antibodies only bind red blood cells at low body temperatures, typically 28–31 °C).
The most common such immunodeficiency is inherited selective IgA deficiency, occurring between 1 in 100 and 1 in 1000 persons, depending on population. They are associated with increased vulnerability to infection, but can be difficult to detect (or asymptomatic) in the absence of infection.
Decreased or absent IgA due to an inherited inability to produce IgA is termed selective IgA deficiency and can produce a clinically significant immunodeficiency. [ 20 ] Anti-IgA antibodies, sometimes present in individuals with low or absent IgA, can result in serious anaphylactic reactions when transfused with blood products that incidentally ...
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.
