STATE OF CELLULAR IMMUNITY IN PURULENT CHOLANGITIS

Abstract

Abstract. Objective: To study the state of the cellular link of immunity in acute and chronic cholangitis. Materials and methods. Cholangitis always worsens the condition of the biliary system. Depending on the magnitude of the pathological changes in the bile ducts, we distinguished three groups of patients. Group I – cholangitis caused by obstruction of the main extrahepatic bile ducts due to choledocholithiasis, group II – cholangitis in conditions of cicatricial strictures of the main bile ducts, and group III – cholangitis in conditions of already performed reconstruction of the duct system. The indicators of the cellular link of immunity were studied separately in each group. The results. The conducted studies indicate an imbalance of the immune system in patients with different courses of cholangitis. The presence of inflammation of a mild degree of severity causes stimulation of almost all links of the immune system, while the cellular branch reacts first. Conclusions. Long-term cholangitis was accompanied by suppression of the main markers of T-lymphocyte differentiation — CD2+, CD3+, CD4+ and CD8+, which take part in antigen presentation, signal transmission to other cells and affect their adhesive properties.
