Allergy: Allergy is a IgE mediated type 1 hypersensitivity reaction

Types of allergy:
. Allergic rhinitis: excessive sneezing
. Hay fever/ allergic bronchitis: coughing, breathlessness
. Skin rash/ urticaria: hives or eruptions over body
. Food allergies: can present as rashes or diarhoea
. Drug reactions: mild reaction has skin rash, can extend to severe breathlessness and choking or severe exfoliation of the skin

Pathophysiology:

Treatment options: Depends on whether symptoms are acute or chronic. In acute reactions, oral or injectable antiallergics are enough, but in severe conditions a systemic or topical steroid may be mandated. Chronic patients need an allergy test to identify what they are allergic to and the outcome decides further course of action.

. Safe
. Quick
. Reliable
. Painless
. Repeatable
. Visible to patient
. Economical

List of allergens:

. Pollen
. Fungus
. Dust
. Animal epithelium
. Foods
. Drugs- custom made list

The outcome of allergy testing:
. Patient lifestyle counselling
. Antiallergic -nasal & oral
. Specific immunotherapy
- Injectable
- sublingual

Specific immunotherapy or desensitization or vaccines for allergy:
Indications
- Failure of medical management
- Poor QLI control
- Recurrence of AFRS

Subcutaneous immunotherapy (SIT):
Injections are made to the antigens a patient is allergic to, as identified by the skin prick testing and four dilution vials are manufactured after intensive protocol of sterilization.

The first dose is administered by the doctor, with medical back up, standby. Once there is no reaction on test dose, the injections will be handed over to the patient for twice weekly dosage for each vial, the whole process taking six months.

Patients who have good response in the intensive phase can move on to the maintenance phase, taking one injection a month for the next 3-6 years.

Oral immunotherapy:
Recommended only for single antigen allergies. larger doses are needed to achieve desired effect.
