Background: The strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting. Objective: The aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for increased asthma severity. Methods: We retrospectively reviewed the clinical charts of 72 patients who received a diagnosis of allergic occupational asthma, with or without associated occupational rhinitis. Results: Our findings suggested that persistent asthma tended to be more common in subjects with associated occupational asthma and rhinitis, and occupational asthma severity was associated with occupational rhinitis severity. Moderate-severe persistent occupational rhinitis is a risk factor for persistent occupational asthma. Conclusions: We demonstrated, for the first time in the occupational setting, a significant association between occupational rhinitis and asthma severity.
