The prognosis after acute irritant-induced asthma is worse than after sensitiser-induced occupational asthma

This is the best study of outcome from acute or recurrent irritant exposures at work. The outcome after 6-8 months was worse than with sensitiser-induced occupational asthma, with more treatment and more exacerbations. Those with single and repeated large exposures had similar outcomes. At follow-up 46% were in their original jobs, 16% in modified jobs, 10% unemployed, 19% off sick and 9% with other outcomes. The identified exposures were mixtures (18), Acids and alkalis (25)Inorganic gasses (6), endotoxin (4) and oxidisers (2)
