X-linked agammaglobulinemia (XLA) is a condition that affects the immune system and occurs almost exclusively in males. People with XLA have very few B . The basic defect in both X-Linked Agammaglobulinemia and autosomal recessive agammaglobulinemia is a failure of B-lymphocyte precursors to mature into.

This applies to standard HIV tests. Patients typically present in early childhood with recurrent infectionsin particular with extracellular, encapsulated bacteria. There are three main types: There are five types of immunoglobulins, but the major one is gamma globulin or immunoglobulin G. View all Images 6 with subscription.

Although persons with XLA carry the burtom to produce immunoglobulins, a genetic defect on the X chromosome prevents their formation. Agammaglobulinemia XLA is similar to the primary immunodeficiency disorder Hypogammaglobulinemia CVIDand their clinical conditions and treatment are dde identical.

The optimal dose is determined by the patient’s response. Stratman MD Lindsay C. It has no ethnic predisposition. Antibodies are made mainly by plasma cellswhich are daughter cells of the B cell line. Present with agammaglobulineemia infections with Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, hepatitis virus, and enterovirus CNS infections. X-linked agammaglobulinemia a primary X-linked immunodeficiency disorder characterized by absence of circulating B lymphocytes, plasma cells, or germinal centers in lymphoid tissues, very low levels of circulating immunoglobulins, susceptibility to bacterial infection, and symptoms resembling rheumatoid arthritis.


It is often secondary to malignant diseases such as leukemia, myeloma, and lymphoma, and to diseases associated with hypoproteinemia such as nephrosis and liver disease. We have sent an e-mail agamaglobulinemia a link to the current page. The dose is based on the patient’s weight and IgG blood-count. If the problem persists, email feedback visualdx.

Immunoglobulins are protein molecules in blood serum that function like antibodies. Rabinovitz MD Christopher J. The aim is to maintain the gamma globulin level above mg per mL of blood.

Because gamma globulin is so important in the production of antibodies and thus in the body’s ability to defend itself against infection, it follows that a deficiency dde absence of gamma globulin would result in severe and recurrent infections. Views Read Edit View history.

The gene for Btk is on the X chromosome. Lymphoid and complement immunodeficiency D80—D85 The carrier’s offspring may inherit the defect and develop the associated disorder.

X-linked agammaglobulinemia

The Btk enzyme plays an essential role in the maturation of B cells in the bone marrowand 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 into the blood stream. B-cell immune deficiency condition, with hypo- or agammaglobulinemia; the immune deficiency becomes bufton as maternally transmitted immunoglobulin levels decline in early infancy.

Reproduced in Buckley CR Since the gene is carried on the X chromosome, XLA individuals are almost always male. Because XLA patients lack antibodies, these tests always give a negative result regardless of their real condition. A mutation occurs at the Bruton’s tyrosine kinase Btk button that leads to a severe block in B cell development at the pre-B cell to immature Agammgalobulinemia cell stage and a reduced immunoglobulin production in the serum.


X-linked agammaglobulinemia Synonyms X-linked hypogammaglobulinemia, Bruton type agammaglobulinemia, Bruton syndrome, sex-linked agammaglobulinemia [1]: Agammaglobuinemia can also rarely result from a spontaneous mutation in the fetus of a non-carrier mother. Schosser MD Glynis A.

This is due to humoral immunodeficiency. B cell — A type of lymphocyte, or white blood cell, that is a key component of the body’s immune system.

Acquired agammaglobulinemia is secondary to other disorders and is usually a hypogammaglobulinemia, that is, a deficiency rather than total absence of this plasma protein. Common symptoms of immunoglobulin deficiency appear after the infant is six months old.

The first immune deficiency was identified in by Ogden Bruton and burtln named X-Linked Agammaglobulinemia or sometimes known as Burton’s Agammaglobulinemia. Local antibiotic treatment drops, lotions are preferred over systemic treatment pills for long-term treatment, if possible.

Mutation — A change in a gene that alters the function or other characteristics of the gene’s product. You have been logged out of VisualDx or your session has expired.

Some patients have a family history of rheumatoid arthritis or allergies.
