The study was undertaken to obtain additional data on the role of neutrophils in the pathogenesis of idiopathic pulmonary fibrosis (IPF). Various functional parameters of neutrophilic functional activity, i.e. phagocytosis, chemotaxis, random migration, oxidative metabolism (3 types of chemiluminescence: spontaneous formylmethionyl peptide-stimulated, and prodigiosan-stimulated), and the level of circulating immune complexes of different size were determined in patients with IPF and healthy individuals. The patients showed a decrease in phagocytosis and an increase in neutrophilic chemotaxis and oxidative metabolism, which was related to the output of toxic oxygen forms. The changes revealed were found to be associated with the activity of an pathological process. The findings suggest that neutrophils can be involved both in the development of and in the occurrence of a pathological process in IPF. |
