[Experience of ribomunyl application in patients with chronic bronchitis]

The authors performed clinical and immunological evaluation of efficacy of treatment of patients with occupational chronic bronchitis (CB) working in contact with pneumotropic pollutants, including airway irritants and dusts. The complex therapy included an immune-correcting agent of bacterial origin, ribomunyl. The indicators to the drug administration were remission or moderate manifestations of the disease with disturbances of mucosal immunity, both isolated (imbalance of IgA, IgG and salivary lysozyme) or combined with systemic immunity disorder (decrease of neutrophilic phagocyte activity, serum IgM and IgG, and the number of T-lymphocytes). The course lasted 3 weeks; the regimen was standard: 3 tablets in the morning before meals 4 days a week. During the whole period of immune correction the patients were under clinical observation; respiratoryfunctions (RF), bronchial hyperactivity, and immune status were evaluated prior to and after the treatment. After the treatment with ribomunyl most patients displayed improvement of the symptoms and FF parameters. The study found significant improvement of a range of immunological parameters: reduction of the imbalance of salivary protective factors, elevation of the phagocyte activity of peripheral blood neutrophils, and a tendency towards increase of IgG and blood T-lymphocyte levels. The results show that clinical, functional and immune parameters normalized simultaneously, with the most evident matching in salivary immunity. The authors conclude that ribomunyl is efficient in treatment of occupational CB when administered with taking individual disturbances of mucosal and systemic immunity into account.
