Type-1 Hypersensitivity Reaction Explained by Dr. Javed: The Allergic Reaction Breakdown!

Welcome to DJMC, where I, Dr. Javed, guide students preparing for medical exams like BUMS, BAMS, BDS, and BHMS. In today’s detailed lecture, we’ll be diving deep into Type-1 Hypersensitivity Reaction, also known as immediate hypersensitivity or allergic reaction. This topic is crucial for your immunology and pathology exams, as it forms the basis for understanding various allergic responses in the body.

What You'll Learn in This Lecture:
What is Type-1 Hypersensitivity?

An overview of Type-1 Hypersensitivity and its classification under the Gell-Coombs Hypersensitivity Reactions.
Mechanism of Type-1 Hypersensitivity Reaction

Sensitization phase: Understanding how exposure to allergens leads to the production of IgE antibodies.
Effector phase: Detailed explanation of how re-exposure to the allergen triggers an immediate allergic reaction due to mast cell degranulation and release of histamine and other mediators.
Mediators of Type-1 Hypersensitivity

Explore the various chemical mediators involved, including histamine, prostaglandins, leukotrienes, and cytokines, and their role in producing allergic symptoms like bronchoconstriction, vasodilation, and inflammation.
Common Examples of Type-1 Hypersensitivity Reactions

Allergic conditions like asthma, hay fever (allergic rhinitis), food allergies, and anaphylaxis will be discussed to illustrate real-life examples.
Diagnosis and Management of Type-1 Hypersensitivity

Diagnostic approaches, including skin prick tests and serum IgE tests.
Treatment protocols such as antihistamines, corticosteroids, epinephrine (for anaphylaxis), and immunotherapy (desensitization).
Clinical Case Study

We'll go through a case study to illustrate the mechanism, diagnosis, and management of an anaphylactic reaction, which is a severe form of Type-1 Hypersensitivity.
By the end of this lecture, you’ll have a thorough understanding of how the immune system responds in allergic reactions, and you'll be better prepared to answer questions related to hypersensitivity reactions in your BUMS, BAMS, BDS, and BHMS exams.
