Furthermore, the immunologic pathway involved in the pathophysiology of AD is complex (table 2). It presents a degree of complexity which has not been appreciated with allergic rhinitis and asthma. In AD both Thl and Th2 T cell products play a role in chronic inflammation, which is maintained by both IL-5 (Th2) and IFN-y (Thl) [51]. In addition recent studies have demonstrated different cytokine expressions in acute (predominantly IL-16) and in chronic (mainly IL-12 and GM-CSF) lesions [52, 53]. 

Allergic rhinitis is a major chronic respiratory disease because of its prevalence, its impact on the quality of life, its impact on work/school performance and productivity, its economic burden, and its links with asthma.
