Pollen-induced asthma and air pollution

Allergic diseases have increased in industrialized countries and this increase is associated not only with genetic factors but also with lifestyle and environmental factors such as air pollution. There is a clinically relevant relationship between the place of residence and clinical decompensation of pollen-induced asthma

. The risk of clinical decompensation in patients from Puertollano Spain (high pollution level)  was up to three times higher than that of patients in Ciudad Real, Spain (low pollution level) (P=0.034) with respect to daily symptoms, medication used and peak-flow measurements.. Furthermore, patients from Puertollano and patients with moderate asthma presented more rapid decompensation compared with patients from Ciudad Real (P=0.020) and patients with mild asthma (P=0.049). Pollen-allergic asthmatics in Puertollano present a poorer clinical course and become decompensated earlier than those from Ciudad Real and it could be due to air pollution.
