AIM: Evaluate immune status in patients with chronic hepatitis (CH) depending on type of causative agent and severity of the infectious process.
MATERIALS AND METHODS: 232 residents of Yakutia including 127 patients with various forms of chronic hepatitis and 105 healthy individuals were examined. Relative levels of mature T-lymphocytes (CD3⁺), T-helpers (CD4⁺), T-suppressors (CD8⁺), B-lymphocytes (CD72⁺) and naturalkillers (CD16⁺) were studied by flow cytometry, as well as concentration of sera immune globulins of classes A, M and G by ELISA.
RESULTS: In patients with chronic hepatitis of various forms, a decrease of expression of differentiating antigens - CD3⁺, CD4⁺, CD72⁺ on the surface of lymphocytes and concentration of sera immune globulins was established. In CHD patients in phase of monoreplication high activity of the infectious process is accompanied by a shift of immune regulatory index to the increase of activity of cytotoxic cells with simultaneous development of deficiency of mature functionally active T-lymphocytes. In the -group of patients with hepatitis D virus with liver cirrhosis normal concentration of sera immune globulins is retained against the decrease of the number of T-helpers and B-lymphocytes.
CONCLUSION: In patients with various forms of viral hepatitis acquired immune deficiency can emerge, which is often accompanied by enhancement of NK-cell activity. The noted reduction of the number of mature functionally active T-cells, as well as main classes of sera antibodies could be con- nected with immune system load during a chronic infectious process.
