[Allergic alveolitis in rural inhabitants]

27 rural inhabitants with allergic alveoltis were evaluated in order to determine the diagnostic usefulness of clinical, radiological, functional examination, BAL, lung biopsy, presence of serum antibodies against environmental antigens in determining the diagnosis and clinical stage of the disease. The effect of therapy and exposition on lung function tests were also discussed. Corticotherapy in most of the patients produced an improvement of vital capacity. In part of the patients isolation from environmental antigens produced stabilization of respiratory parameters. Small dose continuous corticotherapy in patients with prolonged exposition proved to be beneficial and prevented occurrances of acute relapses, as well as decrease of respiratory functional parameters values.
