Aim: Detection of features of functioning ofinnate and adaptive immunity pathways in patients with Darier erythema annulare centrifugum (EAC).
Materials and methods: 14 EAC patients aged 14 - 52 years were examined. The patients were ranked based on therapy variant. The first group consisted of 6 patients who had received Immunovac-VP-4 (Immunovac) against the background of basic therapy; the second group (4 patients) received cagocel against the background of basic therapy; the third group (4 patients) received only basic therapy; the group of healthy individuals consisted of 15 individuals. All the patients had the level ofcytokines in blood sera determined by solid-phase EIA by using Biosource (Austria) test-systems. Evaluation of TLR expression in peripheral blood mononuclear lymphocytes and keratinocytes was carried out by flow cytometry method by using monoclonal antibodies (Catlag Laboratories, USA) against the corresponding antigens; evaluation of content of lymphocyte subpopulations in blood was carried out by using monoclonal antibodies by flow cytometry method on FacsCalibur flow cytometer (Becton Dickinson, USA).
Results: Immunotherapy by Immunovac and cagocel facilitated the increase of CD3+, CD4+, CD8+. Immunovac facilitated a significant increase ofinitially low values ofCD25+, CD95+ and normalization of CD72+; normalization of IgM level. Immunovac increased the level of serum IL-2, induced the increase of IFN-gamma synthesis in contrast to cagocel and basic therapy, the administration of those caused its decrease. TGF-beta increased during the course of Immunovac immunotherapy and decreased during basic therapy. In the course of basic therapy a significant increase of initially high level ofcytokine IL-I beta was observed.
Conclusion: Immunovac therapy resulted in correction of content of lymphocyte populations, sera cytokines, facilitating the normalization of immunocompetent cell proliferation processes, activation of NK-cells, macrophages and at the same time suppression of DTH reactions. Immunovac facilitated the enhancement ofTLR3, 9 expression in the skin that indicates the inclusion ofintracellular receptor mechanisms of innate immunity.
