  1. Value of antibody level in diagnosing anhydride-induced immunologic respiratory disease.

    Article - En anglais

    The objective of this study was to determine whether immunologic anhydride-induced respiratory disease could be predicted on the basis of the level of specific immunoglobulin E (IgE) or immunoglobulin G (IgG) antibody.

    Eighty-one anhydride-exposed employees in one plant were studied.

    Fourteen had disease and 67 did not.

    Immunologic studies were performed by enzyme-linked immunosorbent assay and expressed as titers.

    When optimal discriminant analysis was used, IgE<1 : 5 and lgG ¾ 1 : 10 were found to be the optimal titers for separating employees with and without immunologic respiratory disease caused by anhydrides.

    When IgG ¾ 1 :

    • 10 was used, 62 of 81 workers were correctly classified ;

    • the sensitivity was 100%, the positive predictive value was 45%, the specificity was 75%, and the negative predictive value was 100%. When IgE<1 : 5 was used, 73 of 81 workers were correctly classified ;

    • the sensitivity was 86%, the positive predictive value was 67%, the specificity was 91%, and the negative predictive value was 97%. In conclusion, anhydride disease status can be predicted on the basis of specific lgG or IgE antibody level.
