Allergic rhinitis: an update

Abstract

Allergic rhinitis is extremely common and a global health problem. One study has quoted a prevalence of 16% and, as with asthma, it seems to be increasing. This increase and association with asthma have raised concerns about appropriate treatment. Fortunately, with new knowledge of the pathophysiologic mechanisms, newer and better treatment strategies have been developed. This short review of allergic rhinitis highlights its prevalence, pathophysiology, clinical presentation, investigation and management. A new classification and recommendations by the World Health Organizationís guidelines ëAllergic Rhinitis and its Impact on Asthmaí are also discussed.
