Case Reports in Immunology
|April 12, 2017
Summary
Yeast allergy is a rare cause of reactions to beer, wine, and cider. This case highlights the importance of considering yeast and mold sensitivities in patients with unexplained food and beverage allergies.
Area of Science:
- Clinical Immunology
- Food Allergy Research
- Microbiology
Background:
- Common beer and wine allergies stem from barley or grape proteins.
- Lipid transfer proteins are another known allergen in beer.
- This study explores a rare case involving yeast and mold allergies.
Observation:
- Patient experienced itching, wheezing, and urticaria after consuming beer, wine, and cider.
- Specific IgE testing confirmed allergies to yeast and related food products.
- Co-existing sensitivities to yeast extracts and blue cheese were identified.
Findings:
- IgE reactivity to yeasts and molds was the primary cause of the patient's allergies.
- The patient's symptoms were triggered by alcoholic beverages and yeast-containing foods.
- Diagnosis was confirmed through specific IgE testing.
Implications:
- Yeast allergy is underdiagnosed and should be considered in allergic reactions to alcoholic drinks.
- Patients with yeast allergy require avoidance of specific yeasts in foods and beverages.
- Management includes antihistamines and epinephrine autoinjectors for severe reactions.

Overview
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...
01:30Drug Toxicity: Allergic Reactions
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 exposure to a...
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),...
01:25Microbes in Beverage Production
Alcoholic beverages such as wine, beer, and spirits are the products of microbial fermentation processes that transform simple sugars into ethanol and a wide array of complex flavor compounds. These transformations rely on the metabolic activities of specific yeasts and bacteria, which are selected and controlled to yield the desired beverage characteristics.Wine Fermentation and MaturationWine production begins with the crushing of grapes to release juice and pulp, forming a must that is...
01:27Production of Alcohol
Continuous fermentation is a key strategy in industrial ethanol production, particularly when efficiency, scalability, and high yields are essential. This approach allows for uninterrupted operation and optimized resource utilization. The primary feedstock, corn starch, undergoes enzymatic hydrolysis facilitated by α-amylase and glucoamylase. These enzymes break down the starch into fermentable sugars such as glucose, which are readily assimilated by fermentative microorganisms.Fermentation...
