title: [Indirect immunofluorescence reaction of systemic and local humoral immunity in patients with inflammatory lung diseases. III. Secretory IgA antibodies to S. pneumoniae and H. influenzae autostrains].
abstract: In acute pneumococcal infection with the clinical picture of acute bronchitis or the exacerbation of chronic bronchitis 88-93% of patients showed the formation of secretory IgA to S. pneumoniae autostrains, i.e. a high correlation between the occurrence of these bacteria in the sputum and the local immune response of the body. The characteristic feature of antipneumococcal secretory IgA is their earlier, more intensive and less prolonged formation in comparison with that of serum antibodies. During the exacerbation of chronic bronchitis only in 28% of the patients secretory IgA to H. influenzae autostrains and low correlation between the formation of secretory and serum antibodies were detected.
