Title Case report: Extrinsic allergic alveolitis caused by an isocyanate (isocyanate alveolitis)
Original title Fallbericht: Exogen-allergische Alveolitis durch Isocyanat (Isocyanat-Alveolitis) [in German]
Bibliographic information May 1992, Vol.42, No.5, p.187-189. Illus. 5 ref.
Abstract A 54 year-old worker regularly observed episodes of fever, headache, irritation of the throat, and difficulty in breathing a few hours after exposure to an isocyanate (MDI) hardening agent. Exposure tests with MDI showed that an extrinsic allergic alveolitis developed together with restrictive ventilation, hypoxaemia, fever up to 39.2°C (axillary), and leucocytosis. In the bronchoalveolar lavage (BAL), besides agranulocytosis and eosinophilia, a strong reduction in the CD4/CD8-quotient was observed. After an interval of two years, the presence of antibodies could no longer be shown.
