GONZALEZ LEON, Mayda et al. Prevalence of sensitization to three house dust mites in the allergic infantile population of a family physician's office. Rev Cubana Med Gen Integr [online]. 2005, vol.21, n.1-2. ISSN 0864-2125.

A study was conducted aimed at investigating if the sensitization to these dust mites (Dermatophagoides pteronyssinus [Dp], Dermatophagoides siboney [Ds] and Blomia tropicalis [Bt] ) is a health problem in our infantile population, since the study of the allergic problems has identified the house dust mites as the main agents causing asthma and other affections. 32 allergic children of our office were selected and classified according to their degree of exposure to house dust. All of them underwent the skin test in the right arm. 3 standardized allergenic extracts ValergenÒ (Blomia tropicalis, Dermatophagoides siboney y Dermatophagoides pteronyssinus) of national production (BIOCEN) were used. The prevalence of sensitization was significantly higher (p<0.05) for all the dust mites in patients with a greater exposure to house dust compared with those with lower exposure to it. A higher sensitization was attained for the dust mites of the genus Dermatophagoides. The extract of Dp produced a wheal with a mean size greater than the one caused by other products.
