| Sumario: | The paper confirms long-time opisthorhis invasion role as a risk factor of host immune system reconstitution as well as an important factor in holangiocarcinomas development. It was shown that opisthorhosis invasion primal stage induce host immune system reconstitution. Host immune B-cells system is activated by metacercaria antigens, while the same antigens inhibits T-cells activity. Opisthorhis metabolites stimulate proliferative mithogen-induced T-cells acti vity. Chronic opisthorchis invasion leads to immune system disbalance. It means: decrease of specific and non-speci fic natural killers activity, number of high proliferative activity T-lymphocytes and the shift of regulatory T-cells subset to suppressors prevalence. At the same time specific as well as non-specific T-suppressors functional ability is very low. It was shown T-cells helper-amplifier activation. Despite of circulating B-cells decrease the antibody produced cells number is spleen increases significantly at the same time with circulating immune complexes accumulation. Even 3–6 month after dehelmintisation the immune system disbalance decreases but lefts. In addition, chronic opisthorhis invasion leads to the proliferative processes activation in ductal epithelium, liver, lymph nodes and in other organs which leads to cancer proliferation. According to the results obtained the opisthorhis infected patients needs to be immunocorrected before as well as after dehelmintisation for holangiocancerogenesis profylaxis. |
