What immune deficiencies cause high IgE levels?

The Hyper-immunoglobulin E syndromes (HIES) are rare primary immune deficiencies characterized by elevated serum IgE, dermatitis and recurrent skin and lung infections. There are two forms of HIES: a dominant form caused by mutations in STAT3, and a recessive form, for which a genetic cause is unclear1-4.

Is IgE an autoimmune disease?

There is accumulating evidence to suggest that IgE plays a significant role in autoimmunity. The presence of circulating self-reactive IgE in patients with autoimmune disorders has been long known but, at the same time, largely understudied.

What does IgE level indicate?

IgE is an antibody found in the blood that is a marker for allergy diseases. People who have elevated IgE levels can have environmental or food allergies. If you get a blood test and it shows that you have an elevated IgE that could mean you are an allergic patient.

What does an elevated IgE mean?

Elevated concentrations of IgE are generally thought of in the context of allergic disease. However, increases in the amount of circulating total serum IgE can also be found in various other diseases, including primary immunodeficiencies, infections, inflammatory diseases, and malignancies.

Can high IgE cause fatigue?

These antibodies belong to a category known as immunoglobulin E. In addition to immunoglobulin E, the immune system releases a substance called histamine. When both of these substances produce an inflammatory reaction in the body, you may experience a sense of tiredness alongside other, more obvious allergic symptoms.

Does high IgE mean asthma?

Symptoms Caused by Excess IgE Increased levels of IgE may contribute to symptoms of asthma, such as: Wheezing. Chest tightness. Shortness of breath.

Is IgE an inflammatory marker?

Immunoglobulin E is a key mediator of the inflammatory reactions that are central to the pathogenesis of respiratory diseases such as Asthma. There is evidence that IgE plays a central role in allergic responses to allergens in asthma and rhinitis patients (Bousquet et al., 2006).

Is IgE elevated in lupus?

RATIONALE: Elevated serum IgE concentrations have sometimes been found in systemic lupus erythematosus (SLE) patients. Reasons for these findings and associations with clinical and autoantibody phenotype remain controversial.

What is a normal IgE level for adults?

Normal IgE Levels IgE has the lowest concentration of all antibodies, especially in people without allergies. Normal values may vary in the scientific literature, but the usual reference range is 1.5-144 kU/L (IU/mL) [1, 23].

Can stress cause high IgE?

Higher stress between ages 6 and 18 months was associated with a high total IgE level (OR, 2.03; 95\% CI, 1.1-3.6). Higher stress was significantly associated with increased production of TNF-α, with a suggested trend between higher stress and reduced INF-γ production.

What is the treatment for high IgE levels?

Omalizumab (Xolair®) is the anti-IgE medicine now available. Xolair is made to be similar to natural antibodies and is designed specifically to capture most of the IgE and block the allergic response.

Elevated serum immunoglobulin E(IgE) can be caused by allergies, infections and immune conditions including hyper IgE syndrome (HIES). HIES is a rare primary immunodeficiency disease most commonly characterized by a triad of findings, including increased serum IgE levels, recurrent skin abscesses, and pneumonias leading to pneumatocele formation.

Treatment of Hyper IgE Syndrome. Therapy of HIES remains largely supportive. Antibiotic prophylaxis with trimethoprim-sulfomethoxasole is a frequently used as prophylaxis against recurrent respiratory infections. Treatment for these infections, when they occur, should be started promptly.

What does a low IgE level mean?

Slightly low igm by itself may not mean anything (i.e., your nature level). If it is very low, or other antibodies are also low (or not functioning), it may be a sign of immune deficiency that can lead to more infections.

Does a high IgE level cause cancer?

According to WebMD, most patients would present with other symptoms linked to these diseases. The Memorial Sloan Kettering Cancer Center states that in rare cases, high levels of IgE are caused by IgE multiple myeloma, a bone marrow cancer that stems from plasma cells.
