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.
The cause of selective IgM deficiency remains unclear, although various mechanisms have been proposed, such as an increase in regulatory T cell functions, defective T helper cell functions and impaired terminal differentiation of B lymphocytes into IgM-secreting cells among others. [2]
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.
Low testosterone symptoms in men vary widely, especially across different age groups. If you have low testosterone, it can lead to problems with drive, muscle mass levels, fat distribution, bone ...
X-chromosome. Most antibodies are gamma globulins. Antibodies are made mainly by plasma cells, which are daughter cells of the B cell line.The Btk enzyme plays an essential role in the maturation of B cells in the bone marrow, and when mutated, immature pro-B lymphocytes are unable to develop into pre-B lymphocytes, which normally develop into mature (naive) B cells that leave the bone marrow ...
After their analysis, they determined that men with low total testosterone (below 7.4 nmol/L [213 ng/dL]) had a greater risk of dying from any cause. Further, those with very low levels of ...
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.
Reproductive symptoms in men may include reduced free testosterone (due to the elevation of testosterone-estrogen binding globulin level), [4] diminished libido, erectile dysfunction and (reversible) impaired sperm production with lower mean sperm density, a high incidence of sperm abnormalities, and reduced mobility of the sperm cells.
