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 do IgG levels mean?

This test measures the amount of immunoglobulins, also known as antibodies, in your blood. … An immunoglobulins test usually measures three specific types of immunoglobulins. They are called igG, igM, and IgA. If your levels of igG, igM, or IgA are too low or too high, it may be a sign of a serious health problem.

Can low IgG levels cause fatigue?

Isolated IgG1 deficiency has been reported in chronic fatigue syndrome. As IgG1 is the most abundant IgG subclass, its deficiency often results in hypogammaglobulinemia. Conversely, IgG2 and IgG4 deficiencies manifest in the form of otitis media and sinusitis.

What is normal IgG range?

Serum IgG levels are usually less than 200 mg/dL, and IgM and IgA levels are less than 20 mg/dL. Peripheral blood CD19+ B-cell counts are commonly less than 0.1%. Patients with one of the hyper-IgM syndromes, X-linked or autosomal recessive, have a deficiency of IgG and IgA.

What does it mean if IgG is positive?

Positive IgM and IgG tests for dengue antibodies detected in an initial blood sample mean that it is likely that the person became infected with dengue virus within recent weeks.

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.
