[The immunological reactivity indices of patients with chronic nonspecific lung diseases].

At height of the disease patients with chronic bronchitis showed a reduction of immunological indices of reactivity of the body. A direct dependence was established between the severity of the course of the disease and degree of reactivity reduction. Absence of complete normalization of indices of immunological reactivity at discharge from the clinic indicates incomplete control of the inflammatory process and short-term character of the remission. The reaction of lymphocyte blast transformation may be used for detection of both latent and clinically manifest staphylococcal infection. Increased sensitivity to staphylococcal allergen results in a reduction of the phagocytic activity of neutrophils in patients with chronic bronchitis.
