  1. Follow-up of asbestosis patients and predictors for radiographic progression.

    Article - En anglais

    Objective 

    We followed a group of 85 Finnish asbestosis patients radiographically for an average of 6.5 (range 2 10) years to examine the progression of the disease and to assess possible explanations for the progression.

    Methods 

    The examinations included full-size chest radiographs and a blood specimen analysis.

    The radiographs were classified according to the 1980 International Labor Office (ILO) classification.

    Progression was accepted if the second or third radiography was estimated (in a side-by-side comparison) to have more profusion of small opacities qualitatively than the first. even if the radiographs were classified into the same profusion category.

    Results 

    In all, 38% of the patients showed progression during the follow-up period.

    The average progression of small opacities ranged from ILO 1/1 to ILO 2/2 (0.4 minor ILO categories/year).

    The asbestosis was progressive more often among the sprayers than among the insulators and asbestos factory workers [cross-tabulation, odds ratio (OR) 5.0,95% confidence interval (95% CI) 1.2-20]. In the logistic regression model the ILO classification category at the beginning of the follow-up (OR 1.54 ; 95% CI 0.96-2.47), the fibronectin (OR 1.01 ; 95% CI 1.00-1.01) and angiotensin-converting enzyme (ACE ; OR 1.10 ; 95% CI 1.00-1.20) levels, and the erythrocyte sedimentation rate (ESR ; OR 1.05 ; 95% CI 1.00-1.10) were statistically associated with the radiographic progression of small opacities.
