Exposures causing occupational asthma differer between atopic and non-atopic asthma

This is an interesting approach looking separately at atopic and non-atopic asthma and incidence from a population sample. They also have a category of asthma/COPD overlap. The incidence of atopic asthma was significantly elevated in chemical workers, bakers and food processors, waiters and the unemployed. Non-atopic asthma was increased in metal workers, farmers and other agricultural workers. This approach may help with the elucidation of underlying pathophysiology in non-IgE mediated occupational asthma with latency, which might have several different underlying mechanisms which might affect prognosis and compensation.
