What does a low immunoglobulin G subclass 2 mean?

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. IgG deficiencies can occur at any age. When your body feels it is under attack, it makes special proteins called immunoglobulins or antibodies.

Is IgG deficiency an autoimmune disease?

Autoimmune diseases were more frequent in CVID patients (37.1 %) than in those with selective IgA deficiency (25.5 %) or selective IgG subclass deficiency (12.5 %). Thirty-seven percent of autoimmune episodes occurred prior to the diagnosis of primary antibody deficiency.

What does a low level of IgG mean?

An IgG deficiency is a health problem in which your body doesn’t make enough immunoglobulin G (IgG). Normally, IgG is the most abundant antibody in the blood. It helps prevent infections. So, people with IgG deficiency are more likely to get infections.

What does IgG 2 do?

Upon complex formation, IgG2s can trigger complement-independent, macrophage, and PMN-mediated phagocytic activity, particularly against encapsulated bacteria such as Haemophilus influenzae, Streptococcus pneumoniae, and Neisseria meningitidis (Sanders et al., 1995; Yee et al., 2000).

How do you treat low IgG levels?

Currently, the accepted therapy for IgG deficiency is the intravenous administration of 300-600 mg/kg of IgG once every 3-4 weeks, or 100-200 mg/kg/wk subcutaneously. Higher doses have been shown to be more effective in reducing infections in patients with histories of chronic or recurrent sinopulmonary infections.

What are the causes for low antibody levels?

Low levels of the IgG antibody can also be caused by Waldenstrom’s macroglobulinemia, a rare blood cancer that is characterized by an overproduction of the IgM antibody and subsequent suppression of production of other types of antibodies, including IgG.

What is IgG level?

Immunoglobulin G: IgG is the most common type of antibody in your blood and other body fluids. These antibodies protect you against infection by “remembering” which germs you’ve been exposed to before. If those germs come back, your immune system knows to attack them.
