IMMUNOLOGIC DESENSITIZATION Meaning and
Definition
-
Immunologic desensitization, also known as immune tolerance induction or allergen immunotherapy, is a medical treatment aimed at reducing or eliminating the body's abnormal immune response to certain allergens or foreign substances. It is commonly used to alleviate the symptoms associated with allergies, such as hay fever, allergic asthma, or allergic rhinitis.
During immunologic desensitization, the patient is exposed to gradually increasing amounts of the specific allergen to which they are allergic. This process is typically achieved through regular injections or sublingual tablets containing the allergen extract. The aim is to expose the immune system to small amounts of the allergen over a period of time, allowing the body to slowly build up a tolerance and reduce the allergic response.
The treatment works by helping the immune system recognize the allergen as harmless. Over time, the immune system produces fewer antibodies, such as IgE, and releases fewer inflammatory chemicals, like histamine, in response to the allergen exposure. This can lead to a decrease in the severity and frequency of allergic symptoms and potentially offer long-term relief.
Immunologic desensitization is best conducted under the supervision of a trained healthcare professional, as it involves precise dosing and careful monitoring to ensure safety. It is often recommended for individuals who have not responded well to other allergy medications or whose symptoms significantly impact their quality of life.
In conclusion, immunologic desensitization is a medical treatment that aims to reduce the body's abnormal immune response to specific allergens, offering relief from allergic symptoms by gradually exposing the immune system to the allergen and promoting immune tolerance.

Etymology of IMMUNOLOGIC DESENSITIZATION
The word "immunologic desensitization" is derived from two main terms: "immunologic" and "desensitization".
The term "immunologic" pertains to the immune system, which is the body's defense mechanism against foreign substances or harmful pathogens. It is derived from the Latin word "immunis", meaning "exempt" or "protected".
The term "desensitization" refers to the process of reducing sensitivity or responsiveness to a particular stimulus. It is derived from the prefix "de-", meaning "remove" or "undo", and the word "sensitization", which is derived from the Latin word "sensus", meaning "sense" or "feeling".
Therefore, "immunologic desensitization" refers to the process of reducing or eliminating the body's sensitivity or immune response to a specific substance or allergen, typically through gradual exposure or treatment.
