BACKGROUND: In the pathogenesis of true eczema, an important place is occupied by stress, under the influence of which stimulation of the hypothalamus and brain stem occurs, as well as activation of the hypothalamic-pituitary-adrenal axis and the autonomic nervous system. Stress-induced secretion of neurotransmitters impairs the barrier function of the epidermis, slows wound healing, increases itching and inflammation, and suppresses immunity by changing the immune response of T-helper cells.
AIM: Assessment of the severity of the corrective effect of a course of application of supravenous laser irradiation of blood and broadband medium-wave phototherapy on the blood levels of adrenocorticotropin, cortisol and beta-endorphin in patients with true eczema with a moderate form of the course.
MATERIALS AND METHODS: The study was carried out with the participation of 120 patients with a moderate form of true eczema. Using simple fixed randomization, all patients were divided into 4 groups. The first group (control, n=30) received only basic drug therapy, including the use of detoxification, hyposensitizing, antihistamines and topical glucocorticosteroids. Patients of the second group (comparison group 1, n=30) additionally underwent a course of supravenous laser irradiation of blood. In the third group (comparison group 2, n=30), broadband medium-wave phototherapy was performed against the background of basic therapy. Patients of the fourth group (main group, n=30) in addition to basic therapy received a course of combined exposure to supravenous laser blood irradiation and phototherapy. The concentrations of adrenocorticotropin, cortisol and beta-endorphin were determined in the blood of patients twice (before the start of treatment and 1 month after the start of therapy) using ELISA. The clinical condition of patients in the groups was assessed by changes in the EASI index. Additionally, we studied the dynamics of the level of reactive and personal anxiety using the Spielberger–Khanin questionnaire.
RESULTS: Positive dynamics of adrenocorticotropin, cortisol and beta-endorphin were noted only in the comparison groups and the main group, which proves the high efficiency of correction of the neurohumoral status of patients through a course of complex use of supravenous laser blood irradiation and broadband mid-wave phototherapy. Quantitative changes in the assessed parameters during complex therapy with therapeutic physical factors indicate a supra-additive version of their interaction, realized through different modalities, points of application and mechanisms for realizing the biological potential of physiotherapeutic effects.
CONCLUSION: The results obtained convincingly prove the effectiveness of an additional course of use of supravenous laser irradiation of blood in combination with broadband medium-wave phototherapy when correcting the neuroendocrine status in patients with true eczema. The close correlation between neurohumoral indicators and clinical and psychological patterns of the disease proves the pathogenetic significance of the studied neuroendocrine indicators, which allows us to consider their dynamics as informative criteria for the effectiveness of the treatment.
