  1. Follow up investigation of workers in synthetic fibre plants with humidifier disease and work related asthma.

    Article - En anglais


    To investigate the clinical and sociomedical outcome in patients with various clinical manifestations of humidifier disease and work related asthma after removal from further exposure.

    Methods-Follow up investigation (range 1-13 years) of respiratory symptoms, spirometry, airway responsiveness, sickness absence, and working situation in patients with (I) humidifier fever (n=12), (II) obstructive type of humidifier lung (n=8), (III) restrictive type of humidifier lung (n=4), and (IV) work related asthma (n=22).

    All patients were working at departments in synthetic fibre plants with microbiological exposure from contaminated humidification systems or exposure to small particles (<1 mum) of oil mist.


    At follow up patients with work related asthma were less often symptom free (37%, 7119) than patients with humidifier disease (I, II, III) (67%, 16124).

    Mean forced expiratory volume in one second (FEV,) of patients with obstructive impairment had been increased significantly at follow up but still remained below the predicted value.

    Mean forced vital capacity (FVC) of patients with initially restrictive impairment had returned to normal values at follow up.

    Airway hyperresponsiveness at diagnosis persisted in patients with obstructive impairment (II+IV 14/17, but disappeared in patients with humidifier fever (3/3) and restrictive type of humidifier lung (212). (...)
