title: [Comparison of extracts of cockroaches, house dust and Dermatophagoides with intradermal tests in allergy patients].
abstract: In the order to know both the sensitivity and positivity between the allergenic extracts of cockroach (C), house dust (HDJ, and Dermatophagoides pteronyssinus (Dpt) we made a transversal study in 783 allergic patients who underwent intradermal skin tests with the antigens of C, HD and Dpt. Allergic asthma and rhinitis were the more frequent diagnosis. There was no significative difference between the sensitivity to C and HD (p = 0.1),-women were more sensitive to C than to HD (p < 0.05). We found a greater sensitivity to Dpt than C and HD (p < 001). There were more positive patients to C than to HD (p = 0.01) and although we observed more positive patients to Dpt than to C (p = 0.01) this difference was not significative for women (p = 0.05). We can conclude than cockroach, as an allergic source, has similar importance that house dust mite, and it is inadequate its substitution with house dust extracts in skin tests screening.
