Summary
Patients with atopic diseases like asthma and rhinitis show reduced T-lymphocytes, indicating immune deficiency. Hyposensibilization therapy improved immune cell counts and clinical symptoms.
Area of Science:
- Immunology
- Allergy and Clinical Immunology
Background:
- Atopic diseases such as bronchial asthma and pollinosis rhinitis are common conditions.
- Cellular-mediated immunity plays a crucial role in the immune response to allergens.
Purpose of the Study:
- To investigate cellular-mediated immunity parameters in patients with atopic bronchial asthma and pollinosis rhinitis.
- To assess the impact of specific hyposensibilization on immune status and clinical outcomes.
Main Methods:
- Studied T-lymphocyte subpopulations (suppressor, active, total, helper-suppressor ratio) in patients.
- Utilized blasttransformation test to evaluate lymphocytic reactivity to phytohemagglutinins.
- Compared immune parameters between atopic patients and healthy subjects.
Main Results:
- Patients exhibited a significant reduction in T-lymphocytes and lymphocytic reactivity.
- A higher helper-suppressor ratio was observed in atopic individuals, confirming T-cellular immunodeficiency.
- Hyposensibilization led to increased T-suppressors, active T-cells, and improved clinical symptoms.
Conclusions:
- Atopic diseases are associated with quantitative and functional T-cellular immunodeficiency.
- Specific hyposensibilization can restore immune balance and alleviate clinical manifestations.
- Early diagnosis of immunodeficient states in atopy is crucial for effective management.

Overview
01:27Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
01:24T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

01:30Hypersensitivities
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
