Metabisulfite sensitivity: case report and literature review
Annals of Allergy
|February 1, 1985
Summary
Sulfiting agents in foods and drugs can trigger severe reactions like asthma and anaphylaxis. This study highlights the need for clear labeling of these common additives due to potential health risks.
Area of Science:
- Food Science
- Allergy and Immunology
- Pharmacology
Background:
- Sulfiting agents are common food and drug additives.
- Adverse reactions to sulfites, including life-threatening asthma and anaphylaxis, are increasingly recognized.
- Current FDA regulations permit sulfite addition without mandatory disclosure.
Observation:
- A case of a 34-year-old female with severe, intractable asthma and urticaria is presented.
- Symptoms exacerbated after consuming restaurant meals and using a metaproterenol inhalant solution containing sulfites.
- Bronchial provocation challenge confirmed sulfite sensitivity, showing significant decreases in FEV1 and FEF25-75.
Findings:
- Review of 32 literature cases corroborates the prevalence of sulfite sensitivity.
- Common food and drug sources of sulfites are identified.
- The pathogenic mechanism underlying sulfite sensitivity remains undetermined.
Implications:
- This study underscores the significant health risks associated with sulfite additives.
- There is a critical need for improved regulatory oversight and consumer awareness regarding sulfites.
- The FDA is considering mandatory labeling for sulfite-containing drugs, a step towards mitigating these adverse reactions.
