Individuals with allergic conjunctivitis develop allergy antibodies (IgE) targeted against allergens including pollen, animal proteins, dust mites, mold, and insect droppings. When these IgE antibodies bind allergens, conjunctival inflammation can occur resulting in recurrent eye symptoms of:
Chronic cough refers to a cough that persists for greater than 2 months in duration.
Allergists are considered the experts in evaluating and managing chronic cough. Allergists can complete allergy skin tests and breathing tests as well as order and interpret other tests that may be relevant to your chronic cough.
Eosinophilia represents an abnormal elevation in eosinophils (a type of white blood cell) in peripheral blood or tissue.
Allergists are experts in eosinophilia and diagnose this condition by history, exam, and tests.
Individuals with insect sting allergy develop allergy antibodies (IgE) targeted against insect venom allergens. When these IgE antibodies bind venom after an insect sting, an allergic reaction develops ranging in mild (large local reaction) to life-threatening severity (systemic allergic reaction).
Mast cells are resident cells located in most body tissue including the skin, conjunctiva of the eyes, mucosa of the lungs and digestive system, liver, spleen, bone marrow, and brain. These cells normally play an important role in the immune system protecting the body from infection, but also are involved in allergic disease, urticaria, and anaphylaxis.
Primary immunodeficiency refers to a group of disorders characterized by genetic or heritable immune defects resulting in an impaired ability to fight infection.
Defects in any one of the three arms of the immune system (innate, cellular, humoral) can result in a primary immunodeficiency.
