Allergy And Immunotherapy

Allergy is a medical condition in which our immune system overreactes to certain substances which are other harmless and present commonly around us. The substance to which the allergic reaction occurs is known as allergen. These reactions are acquired, predictable, and at times very rapid. Some people are sensitive to one particular allergen, others may be allergic to many substances. Allergic reactions are the result of activation of certain white blood cells called mast cells and basophils by a type of antibody called immunoglobulin E (IgE). About one third of the population suffer from one or other form of allergy. Children are more frequently affected by the condition than the. Asthma and rhinitis are the common respiratory allergies. Eczema, urticaria and atopic dermatitis are some of the common skin allergies. Risk factors for allergy can be placed in two general categories, namely host and environmental factors. Host factors include heredity, sex, race, and age, with heredity being the most significant. However, there have been recent increases in the incidence of allergic disorders that cannot be explained by genetic factors alone. Infectious diseases during early childhood, environmental pollution, allergen levels, and dietary changes are the major four reasons for major allergies. The common allergic disorders are asthma, allergic rhinitis, anaphylaxis, drug, food, insect allergy, eczema and urticaria. Approximately 20% to 30 % of total population in India suffers from at least one allergic disease. Out of this, about 15% develop Asthma. Urban children have higher prevalence with male predominance. About 4.5% of adolescents are allergic certain food items leading to asthma, rhinitis or both.

Managing allergy is difficult and requires a complete and comprehensive workup. This aims at finding out the exact allergens and then initiating the desensitization programme which helps in long term relief to the patient.

We provide skin prick allergy testing with more than 150 allergens and then according to the individual allergic responses we initiate desensitization using sublingual immunotherapy.

Sublingual immunotherapy or SLIT is relatively simple methods of desensitization, wherein the patient can have the immunotherapy on his/her own without the need for visiting the doctor on regular basis; this ensures compliance with the therapy and also delivers the desired results.
