Humoral immune deficiency 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.

- Quick Answer. Low gamma globulin or hypogammaglobulinemia is a deficiency of gamma globulin and a deficiency in the formation of antibodies, and it can be caused either by primary antibody deficiency syndromes or by a wide range of existing medical conditions. Cases of low gamma globulin are rare, according to Patient.co.uk.

- What It Is. An IgA test measures the blood level of immunoglobulin A, one of the most common antibodies in the body. Antibodies are proteins made by the immune system to fight bacteria, viruses, and toxins.IgA is found in high concentrations in the body's mucous membranes, particularly the respiratory passages and gastrointestinal tract, as well as in saliva and tears. IgA also plays a role in allergic reactions.ntibodies are proteins made by the immune system to fight bacteria, viruses, and toxins.

IgG deficiency IgG has four subclasses: IgG 1, IgG 2, IgG 3, and IgG 4. It is possible to have either a global IgG deficiency, or a deficiency of one or more specific subclasses of IgG. The main clinically relevant form of IgG deficiency is IgG 2. IgG 3 deficiency is not usually encountered without other concomitant immunoglobulin deficiencies, and IgG 4 deficiency is very common but usually asymptomatic.

Causes of Selective IgA Deficiency Article excerpts about the causes of Selective IgA Deficiency: IgA deficiency is caused by faulty white blood cells called B cells or B lymphocytes. While patients have normal numbers of B cells, these cells do not mature into normal IgA-producing cells. Scientists do not yet know the exact cause or causes for these immature B cells.

Overview Selective IgA deficiency is an immune system condition in which you lack or don't have enough immunoglobulin A (IgA), a protein that fights infection (antibody). Most people with selective IgA deficiency don't have recurrent infections. However, some people who have IgA deficiency experience recurrent respiratory tract infections, asthma, sinus infections, allergies and diarrhea. Selective IgA deficiency may also be found with autoimmune disease, in which your immune system attacks particular organs or tissues in your own body. Common autoimmune conditions found with IgA deficiency include rheumatoid arthritis, lupus and celiac disease.

Immunoglobulin A - Review Immunoglobulin A (IgA), in its secretory form, is the main effector of the mucosal immune system and provides an important first line of defense against most pathogens that invade the body at a mucosal surface [1].gA is also found as a monomer in the serum where it may function as a second line of defence by eliminating pathogens that have breached the mucosal surface. Serum IgA interacts with an Fc receptor called FcαR1 triggering antibody-dependent-cell-mediated cytotoxicity (ADCC).

Hypogammaglobulinaemia A state of deficiency of plasma gamma globulins and impairment of antibody formation. The most common cause worldwide is malnutrition. Hypogammaglobulinaemia may be primary or secondary: The primary antibody deficiency syndromes are a rare group of disorders presenting at any age. In the primary form, there is a reduced rate of synthesis of gamma globulins, whereas the secondary form results from an increased rate of breakdown or loss of gamma globulins.

IgA Deficiency IgA deficiency is a defect in the immune system characterized by an inadequate amount of the antibody class known as immunoglobulin A (IgA). Antibodies are large proteins produced by the body to fight infections caused by invaders, such as bacteria, viruses, fungi, parasites, and other foreign agents.

IgA nephropathy IgA nephropathy (IgAN), also known as IgA nephritis, Berger disease (/ b ɛər ˈ ʒ eɪ /) (and variations), or synpharyngitic glomerulonephritis, is a disease of the kidney (or nephropathy); specifically it is a form of glomerulonephritis or an inflammation of the glomeruli of the kidney. IgA nephropathy is the most common glomerulonephritis worldwide. Primary IgA nephropathy is characterized by deposition of the IgA antibody in the glomerulus. There are other diseases associated with glomerular IgA deposits, the most common being IgA vasculitis (formerly known as Henoch–Schönlein purpura [HSP]), which is considered by many to be a systemic form of IgA nephropathy.

IgA nephropathy IgA is a protein, called an antibody, that helps the body fight infections. IgA nephropathy occurs when too much of this protein is deposited in the kidneys. IgA builds up inside the small blood vessels of the kidney. Structures in the kidney called glomeruli become inflamed and damaged. The disorder can appear suddenly , or get worse slowly over many years (chronic glomerulonephritis). Risk factors include: 1  A personal or family history of IgA nephropathy or Henoch Schonlein purpura, a form of vasculitis that affects many parts of the body. 2  White or Asian ethnicity.
