Abstract Work-associated respiratory symptoms may be caused by disorders of both the lower and upper respiratory tract. It is hypothesized that occupational exposures may initiate and/or trigger recurrent hyperkinetic laryngeal symptoms, predominantly episodic dyspnoea, dysphonia, cough and sensation of tension in the throat (work-associated irritable larynx syndrome, WILS). The objective of this study was to examine characteristics of individual and work-related factors that are associated with WILS, occupational asthma (OA) and work-exacerbated asthma (WEA). A total of 448 subjects with WILS, OA and WEA were identified from an occupational lung disease clinic: 50 subjects were identified with OA, 40 with WEA and 30 with WILS. Subjects with the diagnosis of WILS were more likely to be female and more frequently reported symptoms of gastro-oesophageal reflux. The most common triggers of workplace symptoms in the WILS group were odours, fumes, perfumes and cleaning agents. Fourteen patients with WILS identified a specific precipitating event at the workplace at the time of the onset of their symptoms and five of these subjects presented to an emergency department within 24 h of the event. Implications of these findings are discussed.
