| Gefahrenübersicht | An estimated 5% of patients with asthma are sulfite sensitive. Following sensitization, type-I immediate hypersensitivity reactions occur after ingestion. Reactions in asthmatics may occur without evidence of type-I, Ig-E mediation. Patients may present with one or more of the following: flushing, fainting, sneezing, urticaria, angioedema, abdominal distress, bronchospasm, and anaphylaxis. [Ellenhorn, p. 1074] Occupational asthma confirmed in a water plant worker and food workers exposed to sulfites in dust or solution used as a preservative[Malo] Metabisulfites are preservatives used in wines, salad bars, fruits, juices, and shrimp. Onset of symptoms is within minutes. Common symptoms are flushing, low blood pressure, and bronchospasm. [Goldfrank, p. 676] Sulfites are among the drugs and toxins that cause bronchospasm (Table I-3) and anaphylactoid-like reactions (Table I-17). [Olson, p. 8, 28] Sulfites are not classifiable as to carcinogenicity to humans. [IARC] See Potassium metabisulfite for a documented case of occupational asthma. See agents in the category, Sulfites. |
