STATE OF THE PHAGOCYTIC LINK OF IMMUNITY IN CHOLANGITIS

Abstract

Summary. Aim. To study the condition of the phagocytic part of immunity in cholangitis. One of the main ways of elimination of bacterial contamination of the body is the work of the immune system, namely phagocytosis. This especially applies to acute and chronic cholangitis. Materials and methods. Depending on the magnitude of pathological changes in the biliary system, we have identified three groups of patients in whom cholangitis occurs in conditions that progress and worsen. Group I – cholangitis in conditions of choledocholithiasis, group II – cholangitis in conditions of iatrogenic strictures of the main bile ducts, and group III – cholangitis in conditions of already performed reconstruction of the duct system. The functional activity of phagocytic cells was studied. Results and their discussion. It was established that the functional capabilities of neutrophils are depleted in proportion to the severity of cholangitis and its duration. In case of chronic undulating cholangitis, there is an insufficiency of the phagocytic link, phagocytes work on the verge of exhausting their reserve capabilities. Adhesion forces and the potential of intracellular lysosomal enzymes are especially affected. Conclusions. The functional capacity of phagocytic cells in cholangitis is characterized by a deficiency, the degree of virulence is to lie down in the severity of inflammation and thrive. The greatest manifestations of changes were revealed in acid-independent mechanisms of phagocytosis, which were characterized by impaired adhesion and the release of intracellular lysosomal enzymes.
