Description

Allergy medications often prove to be quite beneficial, however not everyone experiences complete relief from allergies. Allergen immunotherapy, which benefits many allergy patients by reducing their symptoms and dependence on medication, is the closest thing we have to a "cure" for allergies. In allergy immunotherapy, allergen extracts are routinely given over the course of years in gradually higher dosages. By turning off the allergy and allergen Immunotherapy modifies how the immune system responds to allergens. The end result is that the people become immune to the allergens, and they can tolerate with fewer or no symptoms. When exposed to an allergen more frequently, the immune system becomes less sensitive to it, most likely as a result of the development of a "blocking" antibody that lowers allergy symptoms.

Allergy shots

The most popular and efficient kind of allergy immunotherapy is allergy shots, generally referred to as Subcutaneous Immunotherapy (SCIT). Asthma and new allergies can be prevented by using this medication, which is the only one that genuinely alters the immune system.

Immunotherapy delivered orally

Another option for treating allergies without injections is sublingual immunotherapy, which is administered under the tongue. Tablets are the only sublingual treatment recognized by the FDA. In the US, allergy drops are used off-label and are not FDA-approved.

Medications

The two most widely used allergy drugs are decongestants and antihistamines. They lessen itching, sneezing, runny nose, and stuffy nose. Other drugs function by stopping the release of the substances that trigger allergic responses. The nose inflammation can be effectively treated with corticosteroids.

Allergen immunotherapy is used to treat allergic rhinitis, allergic asthma, and hypersensitivity to the venom of stinging insects (Hymenoptera). The existence of allergen-specific Immunoglobulin E (IgE) antibodies is confirmed through testing in addition to a medical history and physical examination for the diagnosis of these disorders. The ideal diagnostic method is skin testing via prick or intradermal method; however, in vitro tests, such as serological assays for allergen-specific IgE antibody, provide an option, particularly when skin testing cannot be done. In vitro testing should be carried out to determine the reason in patients with a history that is consistent with venom allergy but negative skin tests. Immunotherapy is an option for patients with a history of venom allergy, negative skin tests, but positive serological tests for IgE antibodies specific to Hymenoptera allergens. Allergen immunotherapy is not appropriate for patients with allergenspecific IgE but no clinical symptoms connected to the identified allergen.

The only treatment option currently available that has a longlasting effect on the condition is specific Allergen Immunotherapy (AIT). The essential tenet of AIT, which still holds true today after being developed more than a century ago, is the administration of progressively higher dosages of the allergen that is causing the reaction. Clinical and immunological tolerance can be successfully induced with this strategy in individuals with allergic rhinitis, asthma, and venom allergies. Rapid desensitisation of basophils and mast cells, induction of regulatory T and B cells, induction of blocking IgG antibodies, and suppression of late-phase responses are a few of the immunological mechanisms involved in the creation of tolerance. AIT has a considerable chance of causing negative reactions, while being effective at treating some allergies. As a result, significant effort is currently being made into creating novel techniques to enhance AIT, such as alterations to allergen preparations and new application methods.
