Abstract

The objective of this panel study was to document the relationship between exposure to cypress pollen and allergic symptoms. The study group included 47 patients with allergy to cypress pollen who completed a daily diary and a weekly evaluation of quality of life (QoL) during the cypress pollen season. Different patients were included in three consecutive pollen seasons: 2014-2015, 2015-2016, and 2016-2017. Daily cypress pollen counts were obtained from the National Aerobiological Network. Air pollution and meteorological data were recorded on a daily basis. The pollen-symptoms relationship was quantified by calculating odds ratios for an increase of 1 log of grains of pollen/m3, taking into account potential confounding factors. The QoL score was expressed with a beta coefficient that increased with 1 grain of pollen/m3. There was a marked increase in rhinitis and ocular symptoms during the pollen season, with a plateau effect at high levels of exposure, but no relationship with bronchial symptoms. The QoL score had a linear and significant relationship with the cypress pollen count. We did not detect any threshold level. This panel study demonstrated a significant association between exposure to cypress pollens and allergic s...Continue Reading

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
