Hypersensitivities

7.7K
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...

COPD: Management Using Bronchodilators and Corticosteroids

831
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Allergic Drug Reactions

1.5K
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...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

1.6K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Antibody Structure

65.7K
Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

    Summary
    This summary is machine-generated.

    Corticosteroid hypersensitivity affects 14% of allergic rhinitis patients, potentially impacting treatment success. This condition is linked to higher IgE and eosinophil levels, and unresponsiveness to intranasal corticosteroids.

    Area of Science:

    • Allergen immunotherapy
    • Clinical immunology
    • Otorhinolaryngology

    Background:

    • Intranasal corticosteroids (IC) are the primary treatment for allergic rhinitis (AR).
    • Approximately 20% of AR patients show treatment failure with IC.
    • Corticosteroid hypersensitivity (CH) is a potential cause of IC treatment failure in AR.

    Purpose of the Study:

    • To determine the incidence of corticosteroid hypersensitivity in AR patients.
    • To identify confounding factors associated with CH in AR.

    Main Methods:

    • 150 AR patients and 50 healthy volunteers were evaluated.
    • Allergic rhinitis diagnosed via symptoms and skin prick tests.
    • Corticosteroid hypersensitivity diagnosed using skin patch tests; IgE and eosinophil counts were measured.

    Main Results:

    • The incidence of CH in AR patients was 14.0% (21/150).
    • CH patients had significantly higher serum IgE and eosinophil counts.
    • AR patients unresponsive to IC showed a higher CH incidence (71.4% vs. 4.4%).

    Conclusions:

    • Allergic rhinitis patients exhibit a high incidence of corticosteroid hypersensitivity (14%).
    • Corticosteroid hypersensitivity may significantly impair treatment response to intranasal corticosteroids in AR.
    • This study represents the largest investigation into CH in AR patients to date.
