The course of allergic alveolitis based on personal experience

The course of allergic alveolitis was observed in 19 patients. The diagnosis was based on medical history, exposition to organic dust, clinical findings, respiratory function and in selected cases on results of transbronchial lung biopsy. All patients presented restrictive patterns of lung function abnormalities. Although a clinical improvement was seen, in none of the patients was a normalization of respiratory function observed. The results of treatment were more promising in patients with a shorter time between the onset of symptoms and making of diagnosis. Isolation from allergens resulted in better effect without prophylactic treatment with prednisone. Steroid therapy did not effect the relapses nor worsening of the respiratory function.
