[Allergic rhinitis due to cockroach antigenic components. An emerging pathology?].
The aim of our study was the evaluation of the role of these insects as causative agents of perennial rhinitis. We studied 317 subjects of both sexes (175 F and 142 M) living in Naples area and examined consecutively in our Centre for perennial nasal symptoms of suspected IgE mediated aetiology. All patients underwent the following diagnostic procedures: anamnestic procedures by using an internal questionnaire, clinical examination, skin prick test by using commercially available allergenic extracts and an allergenic extract containing the whole bodies of Blattella germanica and orientalis, Periplaneta americana. Blood samples for specific IgE determinations and a rhinologic visit were also carried out in patients with cockroach skin Prick test positivity. 14 of 317 subjects, prevalently young males, presented a skin positivity to cockroach allergens. All patients showed a moderate low degree of cutaneous and a low degree of serologic sensitization to allergens of these insects. Our preliminary data seem to demonstrate a mild role of cockroaches as causative agents of perennial rhinitis in Naples area. Further studies are necessary for a more appropriate knowledge of this allergy.
