Περίληψη:
Background: Allergic rhinitis is a global health problem which causes
major illness and represents a risk factor for asthma. The primary aim
of the study was to record the clinical pattern of allergic rhinitis and
its temporal relation with asthma in a Greek population.
Methods: Three-hundred and sixteen subjects with documented diagnosis of
allergic rhinitis in a two-year period were included in this study. All
participants completed a standardised questionnaire with full
retrospective epidemiological data for rhinitis; in addition, serum IgE
measurement and skin prick tests with 22 common inhalant allergens were
carried out, while spirometry was performed in subjects with
self-reported or doctor-diagnosed asthma. All subjects with at least one
positive skin test were included in study analysis.
Results: One-hundred and sixty five out of 316 patients (49.1%) stated
self reported-asthma while in 63/316 (19.9%) asthma was documented with
spirometry. One hundred out of 165 (60.6%) had rhinitis as first
clinical manifestation while in 24/165 (14.5%) asthma symptoms appeared
first; the remaining 31/165 (24.9%) reported simultaneous onset of
upper and lower airways’ symptoms. About 68.5% were sensitised to
seasonal allergens exclusively, while 50% were sensitised to >= 1 of
Parietaria, grasses sp., Olea eur. The duration of rhinitis in the
subpopulation of patients with self-reported asthma (n=165) was
significantly higher compared with non-asthmatics (mean=3.22 years,
p<0.001). Survival analysis for the estimation of asthma onset showed
that the mean time interval with rhinitis only is 16.6 years (median 12
years, incidence 0.0596).
Conclusions: The unique environmental conditions and the aerobiology of
each area clearly affect the clinical features of respiratory allergy.
