allergy and immunology specialist Interview Questions and Answers

1. What are the most common allergens you encounter in your practice?

   • Answer: The most common allergens I encounter are pollen (grass, tree, weed), dust mites, pet dander (cats and dogs), mold, and certain foods (peanuts, tree nuts, milk, eggs, soy, wheat, fish, and shellfish).

2. Describe the difference between an allergic reaction and an autoimmune disease.

   • Answer: Allergic reactions involve an overreaction of the immune system to a harmless substance (allergen), leading to the release of histamine and other inflammatory mediators. Autoimmune diseases, on the other hand, involve the immune system attacking the body's own tissues and organs, mistaking them for foreign invaders.

3. Explain the mechanism of IgE-mediated allergic reactions.

   • Answer: IgE-mediated reactions begin when an allergen binds to IgE antibodies pre-attached to mast cells and basophils. This cross-linking triggers the release of histamine, leukotrienes, and other inflammatory mediators, leading to symptoms like sneezing, itching, hives, and potentially anaphylaxis.

4. How do you diagnose allergic rhinitis?

   • Answer: Diagnosis of allergic rhinitis involves a detailed medical history, physical examination, and allergy testing. Skin prick tests and/or blood tests (RAST) can identify specific allergens triggering the symptoms.

5. What are the different types of allergy testing available?

   • Answer: Common allergy testing methods include skin prick tests (SPT), intradermal tests, and blood tests (RAST or ImmunoCAP). SPT is the most common and involves pricking the skin with a small amount of allergen extract. RAST measures IgE antibodies in the blood.

6. What is anaphylaxis, and how is it treated?

   • Answer: Anaphylaxis is a severe, life-threatening allergic reaction characterized by widespread vasodilation, bronchospasm, and circulatory collapse. Treatment involves immediate administration of epinephrine (adrenaline), followed by supportive care such as oxygen, intravenous fluids, and antihistamines.

7. Explain the difference between food allergy and food intolerance.

   • Answer: Food allergy is an IgE-mediated immune response causing symptoms like hives, swelling, vomiting, and potentially anaphylaxis. Food intolerance involves digestive discomfort, bloating, or diarrhea but does not involve an immune response.

8. How do you manage a patient with a severe peanut allergy?

   • Answer: Management involves strict avoidance of peanuts and peanut products, carrying an epinephrine auto-injector (EpiPen), educating the patient and family on recognizing and managing allergic reactions, and potentially considering immunotherapy if appropriate.

9. What are the common treatments for allergic rhinitis?

    • Answer: Atopic dermatitis (eczema) is an inflammatory skin condition associated with atopy (allergy tendency), while contact dermatitis is an inflammatory skin reaction triggered by direct contact with an allergen or irritant. Patch testing can help diagnose contact dermatitis.

15. What is the role of genetics in allergic diseases?

    • Answer: Genetics play a significant role in susceptibility to allergic diseases. Certain genes influence immune system development and function, making some individuals more predisposed to developing allergies than others. Family history is a key risk factor.

16. Discuss the impact of environmental factors on allergy development.

    • Answer: Environmental factors such as air pollution, exposure to certain chemicals, and hygiene hypothesis (reduced exposure to microorganisms) are all thought to influence the development of allergies.

17. What is the hygiene hypothesis?

    • Answer: The hygiene hypothesis suggests that a lack of early childhood exposure to infectious agents, symbiotic microorganisms, and parasites increases susceptibility to allergic diseases by disrupting immune system development.

18. How do you manage urticaria (hives)?

    • Answer: Management of urticaria involves identifying and avoiding triggers, using antihistamines, and potentially considering other medications like leukotriene inhibitors or omalizumab in severe cases.

19. What is angioedema?

    • Answer: Angioedema is swelling of the deeper layers of the skin, often involving the face, lips, tongue, and throat. It can be allergic or non-allergic and can be life-threatening if it affects the airway.

20. Describe the role of mast cells in allergic reactions.

    • Answer: Mast cells are key effector cells in allergic reactions. They release histamine and other inflammatory mediators upon allergen binding to IgE antibodies on their surface, triggering the symptoms of allergic reactions.

21. What are the different types of immunoglobulins (Ig)?

    • Answer: The major immunoglobulins are IgA, IgD, IgE, IgG, and IgM. Each has distinct roles in the immune system; IgE is particularly important in allergic reactions.

22. Explain the concept of cross-reactivity in allergies.
