Allergic Drug Reactions

898
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...

Hypersensitivities01:30

Hypersensitivities

781
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...

Asthma: Pathogenesis and Management

452
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Area of Science:

  • Allergy and Immunology
  • Emergency Medicine

Background:

  • Anaphylaxis represents a spectrum of allergic reactions, ranging from mild to life-threatening.
  • It is a complex, multi-organ event involving diverse immune cells and mediators.
  • Emergency department visits for anaphylaxis are rising, particularly in pediatric populations.

Purpose of the Study:

  • To review the clinical presentation and diagnosis of anaphylaxis.
  • To highlight the increasing incidence of anaphylaxis.
  • To identify risk factors associated with severe anaphylaxis.

Main Methods:

  • Review of clinical diagnostic criteria from the National Institute of Allergy and Infectious Diseases/Food Allergy and Anaphylaxis Network.
  • Analysis of factors contributing to anaphylaxis severity.

Main Results:

  • Anaphylaxis diagnosis can be supported by established clinical criteria.
  • Older age, delayed epinephrine use, and cardiopulmonary issues are linked to severe reactions.

Conclusions:

  • Anaphylaxis requires careful diagnosis and management due to its potential severity.
  • Understanding risk factors is essential for preventing severe outcomes.
  • Increased emergency visits underscore the public health importance of anaphylaxis awareness.
