Summary
This case study highlights wheat-dependent, exercise-induced anaphylaxis (WDEIA). Diagnostic tools like skin prick tests and specific IgE testing are crucial for identifying this condition.
Area of Science:
- Allergy and Immunology
- Gastroenterology
Background:
- Wheat-dependent, exercise-induced anaphylaxis (WDEIA) is a specific type of food-dependent exercise-induced anaphylaxis.
- Diagnosis can be challenging, often requiring a combination of clinical history and specific diagnostic tests.
Observation:
- A 62-year-old man presented with symptoms consistent with WDEIA.
- The patient experienced anaphylactic reactions specifically after consuming wheat and subsequently engaging in physical activity.
Findings:
- Skin prick tests using both wheat extract and native gliadin extract proved useful in diagnosis.
- Recombinant IgE testing with rTri a 19 omega-5 gliadin further confirmed the diagnosis and its specific triggers.
Implications:
- This case underscores the importance of comprehensive diagnostic approaches for WDEIA.
- Utilizing both skin prick tests with specific extracts and molecular diagnostics aids in accurate diagnosis and management of WDEIA.

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),...

Overview
01:19Hypersensitivity 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...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

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...
