||Work in swine confinement buildings may lead to an inflammatory response and may be associated with increased levels of acute phase proteins. This study compared the inflammatory response of former farm workers who had previously developed respiratory symptoms of wheeze, cough, tightness of the chest during work in swine confinement buildings and had stopped work because of these symptoms, with that of age-matched former farm workers who were known not to have developed such symptoms. Both groups were subjected to an experimental exposure in a swine confinement building for three hours. Complement activation and acute phase proteins were measured in blood samples and broncho-alveolar lavage. Plasma C3d levels correlated significantly with respirable dust. There was complement activation in response to respirable dust, more so among cases than in the control group. It is concluded that acute occupational exposure to organic dust containing endotoxin leads to a weak systemic inflammatory response.
