[Rhinitis and nasal polyps. Their association with domestic acari].
BACKGROUND
In persons older than one year, respiratory allergies can be studied from the etiologic viewpoint using skin test with specific allergens.


METHODS
The objective of this research is to make an assessment of the skin reactivity to mites Dermatophagoides pteronyssinus, Dermatophagoides siboney and Blomia tropicalis in 76 patients with a diagnosis of allergic and nasal polyps which had been treated in Otorhinolaryngologie and sent to the service of allergologie in Esmeralda Camagüey. Every patient received a skin puncture test twice. Fifteen minutes later the hives began to appear and we measured the longer diameter and the perpendicular diameter of every hive and we calculated an average. We also took the average size of the hives in the second test, considering them positive when the medium diameter was < 3 mm and negative when it was < 3 mm. In those patients suffering from rhinitis the greatest positive frequency was for those with Dermatophagoides pteronyssinus and the greatest negative frequency to Dermatophagoides siboney. In patients with nasal polyps there was a positive predominance (p < 0.05) to Dermatophagoides pteronyssinus and a negative predominance (p < 0.05) to Dermatophagoides siboney. So, we many conclude that the mite Dermatophagoides pteronyssinus causes more positive reactions than Dermatophagoides siboney and Blomia tropicalis in those patients with allergic rhinitis and nasal polyps.
