[Treatment of patients with chronic catarrhal bronchitis using bacterial polysaccharides as a way to correct secondary immunologic deficiency].

In mild exacerbation of chronic catarrhal bronchitis secondary immune deficiency manifests itself in a reduced level of the main classes of immunoglobulins (IgA, IgM, IgG) and lowered function of neutrophilic leukocytes. Bacterial lipopolysaccharides (prodigiozan, pyrogenal) are recommended for the correction of the above disorders.
