Therefore, when a person does not have enough IgM, the body may have difficulty fighting infections.

SIgMD can occur in infants, children, or adults..

What is the normal IgM level?

The manufacturer indicates the following reference intervals for healthy adults: IgA 70–400 mg/dl, IgG 700–1600 mg/dl and IgM 40–230 mg/dl [35].

How do you treat low immunoglobulins?

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 is considered a low IgG level?

Usually the IgG level is less than 400 mg/dL; 70% of patients will have very low or absent IgA content. Documentation of impaired production of specific antibodies or poor response to vaccines is fundamental for this diagnosis. Peripheral B-cell numbers may be reduced or normal.

What does low IgG and IgM mean?

For example, IgM antibodies for mononucleosis with or without IgG antibodies means a new mono infection. IgG antibodies without IgM means a past mono infection. People with very low immunoglobulin levels, especially IgA, IgG, and IgM, have a higher chance of developing an infection.

Patients with SIGMD may be asymptomatic; however, commonly present with chronic and recurrent infections; some of them could be serious and life threatening. Interestingly, patients with common variable immunodeficiency with low serum IgM are clinically worse than those with normal IgM levels.

What does an IgM blood test show?

Immunoglobulin M (IgM): Found mainly in blood and lymph fluid, this is the first antibody the body makes when it fights a new infection. Immunoglobulin E (IgE): Normally found in small amounts in the blood. There may be higher amounts when the body overreacts to allergens or is fighting an infection from a parasite.

What causes low IgM?

Other causes of decreased levels of serum IgM (i.e., secondary IgM deficiency) are episodes of infection, thymic hypoplasia, celiac disease, autoimmune disease, and certain adult malignancies; and other PIDs (Wiskott-Aldrich syndrome, DOCK8 deficiency, ataxia-telangiectasia, CVID, and XLA, in combination with IgG and …

What happens if immunoglobulin is low?

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.

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 IgM level?

Immunoglobulin M: Your body makes IgM antibodies when you are first infected with new bacteria or other germs. They are your body’s first line of defense against infections. When your body senses an invader, your IgM level will rise for a short time.

Is High IgM serious?

Hyper IgM syndromes are caused by very rare, one-in-a-million, and potentially life-threatening genetic mutations that severely compromise the immune system and resulting in the individual’s inability to produce antibodies. Patients with hyper IgM are at significant risk for opportunistic and repeated infections.

What is IgM responsible for?

IgM is the first antibody built during an immune response. It is responsible for agglutination and cytolytic reactions since in theory, its pentameric structure gives it 10 free antigen-binding sites as well as it possesses a high avidity.
