[Survey of pathologies caused by sulfites in allergology].

Increased use of sulphites as a preservative for foods and drugs is partly the origin of increasing prevalence of allergy to this anti-oxidant. All organs that are concerned with allergic problems may be affected, especially skin and the digestive tract. We have noted a frequent association between the pathology to aspirin (ORL, bronchial, skin) and that of sulphites: 30.8%. The history is fundamental and compensates for the lack of effectiveness of skin tests.
