BACKGROUND: Analysis of predictors of the effectiveness of various treatment regimens for diseases, as well as the correction of involutionary processes in the human body, is increasingly becoming a standard in scientific medical research. The technology for identifying them traditionally includes the use of correlation and regression analysis, as well as the principles of correlation adaptometry, which makes it possible to approach the solution of this problem from the position of system analysis.
AIM: Analysis of predictors of the effectiveness of correction of involutive skin changes in middle-aged and older women with metabolic syndrome using various therapeutic regimens, including hyaluronic acid laser phoresis and the use of transcranial magnetic therapy in combination with oxygen barotherapy.
MATERIALS AND METHODS: The study was carried out with the participation of 60 patients from middle and older age with involutional changes in the skin against the background of metabolic syndrome. All patients were divided into 2 groups using simple fixed randomization. The first group (comparison, 30 patients) received laser phoresis of hyaluronic acid in the form of a 1.5% sodium hyaluronate gel using a laser and laser-vacuum therapy device LAZMIK. Patients of the second group (main group, 30 patients) were prescribed combined physiotherapy. For transcranial magnetic therapy, the Amo-Atos device with the Headband attachment was used, and oxygen barotherapy was carried out in single pressure chambers of the Oka-MT or Irtysh-Shch1 type under a pressure of 2 atm for 1 hour.
RESULTS: It was found that in the initial state, the quality of life of patients with involutional changes in the skin against the background of metabolic skin syndrome was largely determined by the presence of pathological correlation galaxies that integrate changes in the condition of the skin, metabolic disorders, indicators of oxidative stress and microhemodynamics, and the activity of proinflammatory cytokines. At the same time, the leading role in the deterioration of the quality of life belonged to the age of the patients, the insulin resistance index, transepidermal water loss and microcirculation indicator. However, predictors of effectiveness varied across different treatment regimens. With laser phoresis of hyaluronic acid, its effectiveness increases in younger women with minimal involutional manifestations of skin aging, tested for the condition of the skin, while combined physiotherapy is also most effective in women with a low average age limit, with minimal manifestations of metabolic syndrome and inflammatory processes, as well as against the background of high activity values of one of the enzymes of antioxidant protection ― superoxide dismutase.
CONCLUSION: The results obtained convincingly prove the effectiveness of combination therapy in correcting involutive skin changes in middle-aged and older women due to metabolic syndrome, which is comparable in a number of parameters to the effectiveness of hyaluronic acid laser phoresis. At the same time, predictors of effectiveness depend on the characteristics of the mechanisms of therapeutic action of the treatment regimens used, which allows for a more correct approach to the choice of personalized treatment methods.
