- Transplacental passage of anti-IgA antibodies also can cause IgA deficiency in an offspring by inducing IgA-specific T-cell suppressor activity. This was suggested in a report of 2 mothers with IgA deficiency whose infants had excessive T-cell suppressor function specific for IgA and IgA deficiency.

- This is implicated with induction of suppressor T-cell activity specific for IgA. Agents that can cause IgA deficiency with such mechanisms include sulfasalazine, hydantoin, cyclosporine, gold, fenclofenac, sodium valproate, and captopril. Indeed, 20-40% of patients treated with phenytoin may develop IgA deficiency.

- Low levels or lack of Vitamin A in a human body causes Vitamin A deficiency and it is the number one cause of what is known as preventable blindness in children and severe visual impairment. Mal-absorption of vitamin A by the body can also lead to its deficiency. 2  It can be due to sprue, celiac disease, obstructive jaundice, cirrhosis, giardiasis, cystic fibrosis or an over use of mineral oil as laxative. 3  Over excretion of urine is also known to cause Vitamin A deficiency.

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.

- IgE deficiency, defined in this way, was ob-. served in 7 of 73 normal adults and was not found to be. associated with respiratory tract disease. 80% (35 of 44) of patients with ataxia telangiectasia. (AT) were IgE deficient, 66% were IgA deficient, and. 57% had combined IgE and IgA deficiencies.

- IgA deficiency, a selective lack of immunoglobulin A (IgA). The most common type of immunoglobulin deficiency, it occurs in about 1 in 400 individuals. IgA is a major antibody in the saliva and in the mucous membranes of the intestines and the bronchi. It protects against bacterial and viral infections.gA deficiency, a selective lack of immunoglobulin A (IgA).

IgG Deficiencies An IgG deficiency is a health problem in which your body doesn’t make enough Immunoglobulin G (IgG). People with IgG deficiency are more likely to get infections. When your body feels it is under attack, it makes special proteins called immunoglobulins or antibodies. These antibodies are made by the plasma cells. They are let loose throughout the body to help kill bacteria, viruses, and other germs.

B Cell Deficiency Primary IgA deficiency. IgA deficiency may be primary ,sporadic, or familial. Both serum and secretory IgA are lacking in most patients and, rarely, one or the other. Although certain studies have reported recurrent infections in as many as 50% of IgA-deficient patients, most of these individuals are healthy.

- Imerslund-Grasbeck Syndrome (IGS) Introduction. Imerslund-Gräsbeck syndrome (IGS) is a disorder found in Beagles and Border Collies where dietary cobalamin (vitamin B12) is unable to be absorbed through the gut. Both breeds have independent mutations in the cubulin (CUBN) gene. The disease has an autosomal recessive mode of inheritance with both sexes being equally affected.

Selective IgA Deficiency A common problem in Selective IgA Deficiency is susceptibility to infections. This is seen in about half of the patients with IgA deficiency that come to medical attention. Recurrent ear infections, sinusitis, bronchitis and pneumonia are the most common infections seen in patients with Selective IgA Deficiency. Some patients also have gastrointestinal infections and chronic diarrhea. The occurrence of these kinds of infections is easy to understand since IgA protects mucosal surfaces.

IgG Deficiencies 1 Immunoglobulin G, also known as IgG, is the most common type of IgG deficiencies. 2  People with IgG deficiency are more likely to get infections. 3  Although it’s not known what causes IgG deficiency, genetics may play a role.  A blood test that measures immunoglobulin can diagnose this condition.

Background Selective immunoglobulin A deficiency (SIgAD) is a primary immunodeficiency disease and is the most common of the primary antibody deficiencies. IgAD is commonly associated with normal B lymphocytes in peripheral blood, normal CD4 + and CD8 + T cells, and, usually, normal neutrophil and lymphocyte counts.elective immunoglobulin A deficiency (SIgAD) is a primary immunodeficiency disease and is the most common of the primary antibody deficiencies.

A Low IgG Level: Overview Causes and Development. Low levels of IgG occur in macroglobulinemia. In this disease, the high levels of IgM antibodies suppress the growth of cells that produce IgG. Other conditions that can result in low levels of IgG include some types of leukemia and a type of kidney damage (nephrotic syndrome). Rarely, some people are born with a deficiency of IgG antibodies.

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.gA deficiency is a defect in the immune system characterized by an inadequate amount of the antibody class known as immunoglobulin A (IgA).

Review of sIgAâs major role as a first line of immune defense and new indications regarding inflammation and gut health Immunoglobulin A (IgA, also referred to as sIgA) is an antibody that plays a critical role in immune function in the mucous membranes. More IgA is produced in mucosal linings than all other types of antibody combined; between three and five grams are secreted into the intestinal lumen each day. This accumulates up to 15% of the total immunoglobulin produced in the entire body.

- Most people with an IgA deficiency don't have any symptoms related to the disorder. In these cases, it's found on a blood test, if it's found at all. Some people with an IgA deficiency are more prone to getting certain infections or getting them more often than others. These potential complications can include:

- If IgG or IgA concentrations are decreased, or a deficiency in one of their subclasses is suspected, then subclass testing may be performed to detect and further define the deficiency. Subclass deficiencies can be present even when an immunoglobulin class concentration, such as IgG, is normal.

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.

Growth Hormone Deficiency Growth Hormone Deficiency Causes. Growth hormone deficiency is caused by low or absent secretion of growth hormone from the pituitary gland. This can be caused by congenital (a condition that is present at birth) or acquired (a condition that occurs after birth) conditions.t is not clear if this is clinically important or requires any additional administration. Acquired causes of growth hormone deficiency include infections; brain tumors; and injury, surgery, or radiation to the head. In some cases, no causes can be identified.

- Etiology. Other than genetically determined size, maternal diabetes mellitus is the major cause of large-for-gestational-age (LGA) infants.The macrosomia results from the anabolic effects of high fetal insulin levels produced in response to excessive maternal blood glucose during gestation.he Fenton growth charts provide a more precise assessment of growth vs gestational age (see Figure: Fenton Growth Chart for Preterm Boys and see Figure: Fenton Growth Chart for Preterm Girls).
