Outcome of asbestos exposure (lung fibrosis and antinuclear antibodies) with respect to skin reactivity: an 8-year longitudinal study
Two hundred seventy asbestos workers were examined during an 8-year period. During this time five consecutive surveys were completed. Skin tests with streptokinase-streptodornase (SK-SD), tuberculin (PPD), and phytohemagglutinin (PHA) were performed in the middle of this period. The results of these tests were related to X-ray chest film results and the appearance of antinuclear antibodies (ANA). In all surveys, except the first, X-ray films with small irregular opacities with a profusion greater than or equal to1/1 belonged more frequently to asbestos workers who did not respond to SK-SD or PHA. Thirty-one cases of asbestosis were diagnosed at that time, 23 of them became asbestotic after the skin tests were performed. Asbestotic cases contributed more frequently to the group with energy as compared to asbestos workers lacking asbestosis. Furthermore, asbestosis was correlated with lack of response to second strength of SK-SD in males and PHA in both sexes. Lack of response to these activators was predictive of asbestosis. Asbestos workers with ANA frequently displayed a lack of response to the first strength of SK-SD, PPD, and PHA. This was partly due to the presence of asbestotic cases in the group. However, low responders to all these activators were found frequently in the group with ANA independent of the presence of asbestosis.
