[Immunological reactivity of patients with chronic obstructive bronchitis].

The paper is concerned with the results of a study of the immune status in 14 COB patients and 53 patients with COB aggravated by pulmonary emphysema and chronic cor pulmonale. The immunologic reactivity of patients was compared with that of healthy persons and persons suffering from frequent repeated bronchitides (35). Variations in the indices of humoral and cellular immunity and the phagocytic system were noted in the COB patients as compared to the normal values. The most noticeable shifts in the mean values as well as in disorders of interrelationships of immunological indices were noted in the patients with COB aggravated by pulmonary emphysema and chronic cor pulmonale. A decision rule was proposed for determination of imbalance of indices of the patients' immune system.
