Allergic Reactions: Anaphylaxis

142
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,...

Antibody Structure

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.

Allergic Drug Reactions

1.6K
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...

Drug Toxicity: Allergic Reactions

126
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Area of Science:

  • Food science
  • Analytical chemistry
  • Regulatory compliance

Background:

  • Accurate food allergen detection is essential for meeting legal labeling requirements.
  • Both DNA and protein-based detection methods are employed for food allergen analysis.
  • Each analytical technique presents unique advantages and disadvantages.

Purpose of the Study:

  • To review and compare various methods for food allergen detection.
  • To highlight the pros and cons of protein and DNA-based detection techniques.
  • To discuss the challenges and limitations in current food allergen quantification.

Main Methods:

  • Protein detection: Immunological methods like ELISA and LFDs, and mass spectrometry.
  • DNA detection: Polymerase Chain Reaction (PCR).
  • Evaluation of method sensitivity, specificity, speed, and applicability to processed foods.

Main Results:

  • ELISA offers quantitative, sensitive, and rapid results; LFDs are suitable for on-site industrial use.
  • PCR provides high specificity and good sensitivity but is affected by processing and matrix factors.
  • Mass spectrometry shows potential but is complex, time-consuming, and sensitive to food processing.

Conclusions:

  • No single method currently provides absolute quantification of food allergens.
  • Antibody-based methods (ELISA, LFD) can struggle with processed foods, potentially yielding false positives.
  • Laboratory calibration of available methods enables reliable measurements despite inherent uncertainties.
