Abstract
BACKGROUND: Vitiligo is a chronic acquired disease with a genetic predisposition to pigmentation disorder caused by the destruction of skin melanocytes, leading to hypopigmentation. The effectiveness of currently available methods of treatment of vitiligo, on average, is about 40%. Therefore, it is necessary to search for new effective and safe methods of vitiligo therapy, characterized by minimal risk of side effects, and financial costs of the patient. Simvastatin inhibits cholesterol biosynthesis by inhibiting HMC-CoA reductase. In addition to lowering cholesterol, statins have pleiotropic effects, namely, they inhibit various inflammatory mediators and cytokines, activate the antioxidant system, and reduce the level of active forms of oxygen in melanocytes. AIMS: To develop a pathogenetic therapeutic complex using simvastatin for patients with vitiligo. MATERIALS AND METODS: To participate in the study, 81 patients with vitiligo were examined. Each patient was determined by the form and stage of the disease. The effectiveness of therapy in the groups was evaluated by assessing the area of repigmentation. The first group received treatment ― simvastatin in combination with UVB therapy 311 nm, the second group-UVB therapy 311 nm. Studies of cytokines were carried out using enzyme immunoassay. Study of the oxidative status using high-performance liquid chromatography-mass spectrometry. Statistical processing of the research materials was carried out using the SPSS Statistics software package. RESAULTS: The combined method of therapy with the inclusion of simvastatin showed the following clinical results: 6 (12%) had a pronounced positive effect; improvement ― in 34 (69%) patients. Dynamics of the immune profile: decrease in IL-6 from 101 to 8.10.6; TNF- from 18.82.1 to 12.91.1; increase in IL-10 from 3.20.4 to 7.30.3. Dynamics of the oxidative profile: malondialdehyde 1.70.12 to 1.480.11, 8-oxo-DG 0.300.03 to 0.230.02, SOD 1703 to 2077, glutathione 69736 to 94232. CONCLUSION: The combined method of vitiligo therapy with the inclusion of simvastatin is effective and safe, leading to stabilization of the process, clinical improvement and a pronounced effect of therapy in 82% of patients. It also has an immune-correcting effect and normalizes the indicators of the oxidative profile.
