Hypogammaglobulinemia is an immune system disorder in which not enough gamma globulins are produced in the blood (thus hypo-+ gamma + globulin + -emia). This results in a lower antibody count, which impairs the immune system , increasing risk of infection.
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.
Diagnosis is chiefly by exclusion, i.e., alternative causes of hypogammaglobulinemia, such as X-linked agammaglobulinemia, must be excluded before a diagnosis of CVID can be made. Diagnosis is difficult because of the diversity of phenotypes seen in people with CVID. For example, serum immunoglobulin levels in people with CVID vary greatly.
It is unknown what specifically causes infantile transient hypogammaglobulinemia. The following are some of the hypothesized mechanisms: 1) defective T cells that prevent B cells from stimulating the proper synthesis of antibodies; 2) maternal IgG suppresses the production of IgG; 3) low levels of vital cytokines; and 4) genetic variations in families predisposed to immunodeficiency.
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.
How it causes swelling is thought to be due an osmotic shift. When there’s more ‘stuff’ in your blood — in this case sugar — and you suddenly reduce the amount of stuff in the blood, it ...
Dementia impacts almost 10% of older adults in the U.S. While scientists haven’t pinpointed exactly what causes it, research is slowly identifying new factors, like diet, that may play a role in ...
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 ...
