Allergic 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...
Hypersensitivities01:30

Hypersensitivities

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...
Allergic Reactions: Anaphylaxis01:30

Allergic 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),...
Hypersensitivity Reactions: Immune-Complex Reactions01:19

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...

Summary
This summary is machine-generated.

Allergies to scaly pets like iguanas can occur, contrary to common assumptions. This case study confirms iguana allergy in a patient with allergic rhinitis and asthma symptoms.

Area of Science:

  • Dermatology
  • Allergology
  • Zoology

Background:

  • Furry pets are known causes of allergic rhinitis and asthma.
  • Scaly animals, such as lizards, are generally not considered allergenic.

Observation:

  • A patient presented with allergic rhinitis and asthma symptoms exclusively at home.
  • Initial allergy tests for common pets and aeroallergens were negative.
  • Symptoms worsened upon exposure to pet iguanas.

Findings:

  • Skin prick testing with iguana scale extract yielded a positive result.
  • Immunoassays confirmed the presence of IgE antibodies to iguana in the patient's serum.
  • The patient was diagnosed with a specific allergy to iguana.

Implications:

  • Physicians should consider non-traditional pet allergies, including those to reptiles.
  • Allergy assessments should include a comprehensive history of pet exposure, regardless of animal type.
  • Awareness of potential allergens from scaly pets is crucial for accurate diagnosis and management.
