Humoral immune deficiency (including B cell deficiency or dysfunction), with signs or symptoms depending on the cause, but generally include signs of hypogammaglobulinemia (decrease of one or more types of antibodies) with presentations including repeated mild respiratory infections, and/or agammaglobulinemia (lack of all or most antibody production) which results in frequent severe infections ...
This is a list of primary immunodeficiencies (PID), which are immune deficiencies that are not secondary to another condition.. The International Union of Immunological Societies recognizes nine classes of primary immunodeficiencies, totaling approximately 430 conditions.
The precise symptoms of a primary immunodeficiency depend on the type of defect. Generally, the symptoms and signs that lead to the diagnosis of an immunodeficiency include recurrent or persistent infections or developmental delay as a result of infection. Particular organ problems (e.g. diseases involving the skin, heart, facial development ...
Common variable immunodeficiency (CVID) is an inborn immune disorder characterized by recurrent infections and low antibody levels, specifically in immunoglobulin (Ig) types IgG, IgM, and IgA. [2] Symptoms generally include high susceptibility to pathogens, chronic lung disease , as well as inflammation and infection of the gastrointestinal tract.
T cell deficiency is a deficiency of T cells, caused by decreased function of individual T cells, it causes an immunodeficiency of cell-mediated immunity. [1] T cells normal function is to help with the human body's immunity, they are one of the two primary types of lymphocytes (the other being B cells). [medical citation needed]
Interleukin-1 receptor-associated kinase deficiency is an inherited disorder of the immune system. [6] This immunodeficiency leads to recurrent infections caused by the pyogenic bacteria, for example Streptococcus pneumoniae, Staphylococcus aureus and Pseudomonas aeruginosa, but not by other infectious agents.
Selective immunoglobulin A (IgA) deficiency (SIgAD [1]) is a kind of immunodeficiency, a type of hypogammaglobulinemia. People with this deficiency lack immunoglobulin A (IgA), a type of antibody that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract.
IgG deficiency is a form of dysgammaglobulinemia where the proportional levels of the IgG isotype are reduced relative to other immunoglobulin isotypes.. IgG deficiency is often found in children as transient hypogammaglobulinemia of infancy, which may occur with or without additional decreases in IgA or IgM.
