What is anti IgE receptor antibody?

Anti-IgE is a form of treatment for allergic conditions that has been approved for the treatment of moderate to severe persistent asthma and chronic idiopathic urticaria (hives with an unknown cause). Anti-IgE interferes with the function of IgE. IgE is an antibody in the immune system.

What autoimmune diseases cause high IgE?

Elevated total IgE levels are frequent in patients with autoimmune pancreatitis (21, 112), and it was recently suggested that analysis of total IgE in serum might be useful in the differentiation between autoimmune pancreatitis and pancreatic carcinoma (113).

What disease is IgE associated with?

Elevated levels of total serum IgE are associated with many diseases, including allergic bronchopulmonary aspergillosis (ABPA), parasitosis, atopic dermatitis, adult HIV infection, hyper-IgE (Job’s) syndrome, Sézary’s syndrome, IgE myeloma, and Kimura’s disease[1].

What is the function of IgE antibodies?

Immunoglobulin E (IgE) antibodies are well known for their role in mediating allergic reactions, and their powerful effector functions activated through binding to Fc receptors FcεRI and FcεRII/CD23.

What do IgE test results mean?

What do the results mean? A total IgE test result that is high means that you may have some kind of allergy. But the results of a total IgE test don’t show what you’re allergic to or how serious your allergy may be. A specific IgE test result that is high means that you may be allergic to the allergen that was tested.

What does IgE mean in a blood test?

Immunoglobulin E (IgE) is an antibody that is produced by the body’s immune system in response to a perceived threat. It is one of five classes of immunoglobulins (A, G, M, D, and E) and is normally present in the blood in very small amounts. This test measures the amount of IgE in the blood.

What causes high IgE levels?

Diseases which cause the elevation of serum IgE levels include atopic diseases (asthma, allergic rhinitis, atopic dermatitis, urticaria), parasitic diseases, cutaneous diseases, neoplastic diseases, and immune deficiencies [3].
