[Dynamics of the indices of the immune system as affected by endobronchial laser therapy in patients with complicated tuberculosis of the lungs].

The results of study of the local and humoral immune defense during endobronchial laser therapy of nonspecific endobronchitis in patients with newly diagnosed pulmonary tuberculosis are presented. Laser therapy proved to have no negative action on the humoral immunity in pulmonary tuberculosis patients during treatment of catarrhal and purulent endobronchitis, while a marked increase in IgM levels, thus rapidly reacting and well opsonizing antibodies can be regarded as a positive or stimulating the impact on the whole immune system. Endobronchial laser therapy for catarrhal and especially purulent inflammatory bronchial process in the multimodality treatment of patients with newly diagnosed pulmonary tuberculosis normalized parameters of the local immune system, especially that of locally secreted immunoglobulins, i.e. helium-neon laser radiation has a favourable influence on local immune defense, which is essential in increasing the efficacy of therapy of this category of patients.
