P06 - Pulmonary functions are affected during pollen season in children with allergic rhinitis

چکیده
Results Thirty patients (17 male, 56.7%) with a median age of 11.5 (8.7-13.6) years were included. 12 patients (40%) had mild allergic rhinitis, whereas 18 (60%) had moderate-persistent allergic rhinitis interfering with daily activities. There was no significant difference at spirometric parameters including forced vital capacity (FVC), forced expiratory volume at 1 second (FEV1) and FEV1/FVC ratio, which obtained in and out of pollen season. However, the forced expiratory flow between the 25 and 75% of the vital capacity (FEF25-75) (100 (91-96) vs. 91 (83-104)) and peak expiratory flow (PEF) (92 (83-97) vs. 82 (76-94)) values were significantly lower in pollen season when compared with the values obtained out of pollen season. Conclusion Pulmonary functions may be affected in children with pollen-induced allergic rhinitis during pollen season even if they have no history and symptoms of bronchial asthma.

متن کاملAlpha2-macroglobulin and eosinophil cationic protein in the allergic airway mucosa in seasonal allergic rhinitis.
As previously demonstrated in seasonal allergic rhinitis, increased microvascular permeability and eosinophil activation are key features of allergic airway inflammation. In the present study, the hypothesis that exudation of alpha2-macroglobulin may cause the appearance of eosinophil cationic protein (ECP) in the airway lumen was explored. Nasal lavages were carried out using the nasal pool de...

Recent evidence suggests that nasal irrigation with hypertonic saline may be useful as an adjunctive treatment modality in the management of many sinonasal diseases. However, no previous studies have investigated the efficacy of this regimen in the prevention of seasonal allergic rhinitis-related symptoms in the pediatric patient. Twenty children with seasonal allergic rhinitis to Parietaria we...
