[Reactivity of the blood phagocytes in patients with chronic bronchitis]

Bactericidal and migration activity of neutrophils was investigated in 53 patients with chronic bronchitis by means of a spontaneous and induced (6 stimulators) NBT-test and in 18 patients by means of skin fenestrae. A spontaneous NBT-test (sNBT-test) was shown to reflect the activity of an inflammatory bronchial process and to decrease by the end of therapy indicating complete remission. A stimulation index was in reverse correlation with sNBT-test indices. Response of neutrophils to various stimuli leveled down with an increase in sNBT-test indices. In an inflammatory bronchial process inhibition of neutrophil migration into a zone of inflammation was noted, particularly in patients with lingering exacerbation. Dependence of a stimulating effect on a sNBT-test value and disorder of neutrophil migration activity should be taken into account in administration of one or another immunostimulator.
