[Clinico-immunological study of 16 cases of benzoate intolerance in children].

The authors report a sery of 16 cases of intolerance to the benzoates in children. Sixteen children (9 boys and 7 girls) were directed to the Hospital of Tarbes from June 1995 to July 1995, for recurring urticaria (7/16) combined with asthma (1/16), atopic eczema (2/16), dermorespiratory syndrome (2/16) and asthma (1/16). All were subject to an immunological examination comprising alimentation inquiry, prick test, IgE determination, RAST, oral provocation test to benzoates, which establishes the diagnosis, whose confirmation is certified by the benefit of the food eviction. To conclusion, the authors underline several points: the presumable underestimation of the intolerance, the often mentioned atopic familial context, the observed pathology (urticaria, asthma, eczema), the importance of the provocation test. Finally, besides food such as grey shrimps, sodas and antibiotic syrups, one finds benzoates in the antiallergic syrups initially prescribed as a preventive measure.
