Resumen

MEYER K, ANDREA; BARRERA T, TEODORO  y  HIDALGO T, HUGO. Dust mite allergic sensitization in children aged 1 month to 5 years-old using specific IgE determination by unicap fluoroimmunoassay. Rev. chil. enferm. respir. [online]. 2007, vol.23, n.2, pp.94-98. ISSN 0717-7348.  http://dx.doi.org/10.4067/S0717-73482007000200003.

Dust mite sensitization is considered a major risk factor for pediatric asthma; however, there are few data about early sensitization in Chilean children available. This study aimed to investigate allergic sensitization to mites in infancy and early childhood. The patient population, 224 children aged 0 to 5 years with suspected respiratory allergy, was divided into 3 groups of age: 1 to 12 months-old, 13 to 35 months-old, and 3 to 5 years-old. Sensitization status was ascertained by assessing the specific IgE to mite by UniCAP fluoroimmunoassay (Pharmacia). Sixty eight (30.6%) patients were sensitized to mites. The frequency and level of sensitization increased with the age of the children. Our data support that avoidance measures in the domestic environment aimed at the primary prevention of mite-driven sensitization should be introduced at the earliest possible stage

Palabras clave : dust mites; dermatophagoides; early sensitization.
