The state of prooxidant-antioxidant homeostasis and immune status in patients with lichen planus and its correction

Objective - increasihg the effectiveness of treatment for patients with lichen planus by developing an improved tactic of complex differential therapy, taking into account changes in the parameters of prooxidant-antioxidant homeostasis, immune status of the organism and clinical manifestations of dermatosis. Material and methods. Under the supervision were 124 patients with lichen planus (85 women, 39 men) aged 24 to 67 years. In patients with lichen planus, the parameters of prooxidant-antioxidant homeostasis and immune status were determined before and after standard treatment (I comparative group - 42 patients), standard treatment with the inclusion of quercetin preparation (II comparative group - 41 patients) and the developed complex treatment using quercetin, polyenzyme preparation and low-intensity laser therapy with antioxidant and anti-inflammatory effects (III - main group - 41 patients) by known methods. Results. The modern tendencies of morbidity and clinical features of the course of lichen ruber planus have been investigated. A significant increase in patients with lichen ruber planus activity of the processes of free radical oxidation of lipid and protein structures with the formation of oxidative stress and the state of endogenous intoxication were established. Changes in phagocytosis, increase in serum levels of circulating immune complexes and certain proinflammatory cytokines were defined in patients with lichen ruber planus, their dependence on the nature of the clinical course of dermatosis was determined. An improved method of complex treatment of lichen ruber planus with the use of quercetin, a polyenzyme medication and low-intensity laser therapy with antioxidant and anti­inflammatory action has been developed. Conclusions. The developed advanced complex treatment of lichen planus patients with combined and differentiated use and the background of standard therapy for quercetin, a polyenzyme preparation, and low-intensity laser therapy with antioxidant and anti-inflammatory effects contributes to the normalization of prooxidant-antioxidant homeostasis, phagocytosis, circulating immune complexes of cytosets and studied pro-inflammatory direction, and also likely to improve short- and long-term clinical outcomes of therapy for such patients.
