Skin and serum reactivity to some storage mites in children sensitive to Dermatophagoides pteronyssinus.
The incidence of skin test and RAST positivity for Dermatophagoides farinae and storage mites (Glycyphagus privatus, Lepidoglyphus destructor, Tyrophagus putrescentiae, Acarus siro, and Gohieria fusca) have been evaluated in children with bronchial asthma and positive prick test to Dermatophagoides pteronyssinus. The storage mite with highest incidence of skin and RAST positivity was Gohieria fusca, which caused a positive response in more than 50% of the children evaluated. This antigen appears to possess allergenic determinants not present in Dermatophagoides pteronyssinus. The sensitivity to this antigen might be considered in house dust mite-allergic children who do not improve after specific immunotherapy with Dermatophagoides pteronyssinus extracts.
