Allergie aux pollens de Cyprès

Abstract

Cupressaceae pollen allergy has increased in the Mediterranean region in recent decades. This allergy constitutes one of the few causes of respiratory allergy of winter. With regards to its clinical manifestations, rhinitis and conjunctivitis are more frequent than asthma. There has been a progressive increase in the total and annual concentration of Cupressaceae pollen, the reasons for which are the parallel increase in the planting of these trees and the global hothouse effect with the resulting climate change, both of which increase the production of pollen and their concentration in the ambient air. The effectiveness and safety of specific immunotherapy for Cupressaceae allergy were demonstrated some years ago in double-blind, controlled studies in which either traditional subcutaneous therapy or sublingual therapy were used.
