L.; VASCONCELLOS, C.BackgroundEpicutaneous test made with dust mite antigens. ObjectiveEvaluation of the response of the epicutaneous test withAleuroglyphus ovatus antigen in atopic patients. MethodsWe patch tested 119 individuals, 48 with atopic dermatitis, 50 with respiratory allergy and 21 healthy controls. We compare the positive response frequency to a closed patch test usingAleuroglyphus ovatusantigen in different concentrations and 48 and 96h reading times among those individuals. ResultsSix patients with atopic dermatitis (12.5%) and 4 with respiratory atopy (8.0%) had positive reactions. None of the non-atopic controls had a positive response. As the antigen concentration raised, the number of positive reactions to epicutaneous test raised as well. ConclusionOur data suggest a positive relation between Atopy Patch Test positive responses andAleuroglyphus ovatusantigen concentration, no matter the kind of the atopic clinical expression.

An investigation was conducted to define the involvement of Toll-Like Receptors (TLRs) 2 and 4 in localized (LD) and disseminated (DD) dermatophytosis due to T. rubrum. Fifteen newly diagnosed patients, eight patients with LD and seven with DD, defined by involvement of at least three body segments were used in this study. Controls comprised twenty skin samples from healthy individuals undergoing plastic surgery. TLR2 and TLR4 were quantified in skin lesions by immunohistochemistry. A reduced expression of TLR4 in the lower and upper epidermis of both LD and DD patients was found compared to controls; TLR2 expression was preserved in the upper and lower epidermis of all three groups. As TLR4 signaling induces the production of inflammatory cytokines and neutrophils recruitment, its reduced expression likely contributed to the lack of resolution of the infection and the consequent chronic nature of the dermatophytosis. As TLR2 expression acts to limit the inflammatory process and preserves the epidermal structure, its preserved expression may also contribute to the persistent infection and limited inflammation that are characteristic of dermatophytic infections.
