[Nasal eosinophilia after specific provocation in patients with perennial allergic rhinitis].

We studied 35 patients with perennial allergic response to know the eosinophilia after the nasal challenge with specific antigen. Patients were selected randomly. In each patient, history and clinical examination, cutaneous tests, and eosinophil count in nasal mucous membrane were done 30 minutes and 8 hours after the challenge with Dermatophagoides antigen Results showed a significant increase of eosinophils after the challenge (P.006). Significant differences were not discussed between the eosinophil counts obtained 30 minutes and 8 hours after the challenge.
