Primary Agammaglobulinemias are a group of inherited immune deficiencies characterized by insufficient antibodies; Antibodies are composed of certain proteins immunoglobulins that are essential to the immune system; They are produced by specialized cells (ie, B lymphocytes) that circulate in the lymphatic fluid and blood; Antibodies fight off bacteria, viruses, and other foreign substances that threaten the body; Agammaglobulinemias are also characterized by the abnormal function of specialized white blood cells called B lymphocytes; The B lymphocytes are supposed to search out and identify bacteria, viruses, or other foreign substances in the body; T lymphocytes, also known as the "killer cells," assist B lymphocytes to respond to infection and other antigens; However, in some forms of Primary Agammaglobulinemias, neither the B nor the T lymphocytes function normally;There are three types of Primary Agammaglobulinemias: X-linked Agammaglobulinemia (XLA), X-linked Agammaglobulinemia with growth hormone deficiency, and autosomal recessive Agammaglobulinemia; All of these disorders are characterized by a weakened immune system treated with hyperimmune gamma globulin injections.
