To examine whether diffuse pleural thickening (DPT) causes impairment of pulmonary function independent of other manifestations of asbestos-related disease, we studied individuals selected from 1,150 men with occupational asbestos exposure who had undergone pulmonary function testing and computed tomographic (CT) scanning. The CT scans revealed 84 subjects with DPT as defined for CT. Of these 84 subjects, 53 eligible study cases were matched by age with a referent group without DPT from the same exposed group. No difference was demonstrated between cases and referents in smoking history, length of exposure, latency, or the proportion with either interstitial fibrosis or pleural plaques. Individuals with DPT demonstrated significantly reduced forced vital capacity (FVC) (p = 0.002) and diffusing capacity for carbon monoxide (DLCO) (p = 0.002) as compared with the referents. No difference was found in the two groups' FEV1 to FVC ratio (FEV1/FVC). Individuals with DPT and either interstitial fibrosis or pleural plaques showed a significantly lower FVC than did those with fibrosis or pleural plaques alone. Individuals with DPT and rounded atelectasis had similar pulmonary function to those with DPT and no rounded atelectasis. Subjects with DPT had a more frequent history of coronary bypass surgery than referents (19% versus 2%; p = 0.008). We conclude that subjects with DPT have restrictive pulmonary function and reduced diffusing capacity independent of other manifestations of asbestos-related disease.
