Cockroach XXXX : case report and literature review.

@entity1 @entity565 @entity56 @entity2490
Among the different antigens, insects play an important role in the induction of @entity56 . We report on a 12-year-old @entity1 with family history of atopy, who developed symptoms of @entity2490 and perennial @entity565 since the age of 5. @entity1 's symptomatology increased during pollination and kept close relationship to domestic antigens. A skin and inhalation test with an extract of domestic dust was positive. An investigation about potential allergens was initiated and the @entity1 mentioned that was a significant amount of cockroaches at his home. Skin tests, RAST and bronchial provocative tests with a cockroach extract gave positive results. Bronchial provocative tests with a cockroach extract gave immediate and late responses, as has been evidenced by different authors. Immunotherapy has been successfully employed, partly due to the difficulties inherent to an efficient way of preventing insect contact. Improvement of symptomatology correlates well with blocking antibody production and the reduction in white cell sensitivity to the antigenic system. Finally, the potential relevance of @entity56 in our country be underlined. Cockroach sensitivity should be considered in every @entity1 with perennial @entity565 , in which the usual allergens have been excluded.
