Вплив дисліпідемії і інсулінорезистентності на перебіг гніздової алопеції, асоційованої з метаболічним синдромом

Abstract

Alopecia areata (AA) is a tissue-specific disease of the hair follicles, manifested by foci of alopecia on a scalp and other areas of skin. The objective of our study was to evaluate the values of blood lipids and carbohydrate metabolism in patients with АА associated with metabolic syndrome (MS) to determine the relationship between disease severity and metabolic disorders. Materials and methods. Clinical and anamnestic characteristics and laboratory values of lipid spectrum and carbohydrate metabolism were analysed in 50 patients with AA associated with MS. Results. As a result of the study, the following regularities have been established: values of blood lipids (cholesterol, triglycerides, high-density lipoproteins) and carbohydrate metabolism (blood glucose, glycosylated haemoglobin, HOMA index) statistically significantly deteriorate with increasing number of the MS components (p <0.05); in patients with mild AA there is a statistically significantly (p <0.05) smaller number of MS components compared with patients with moderate to severe forms (φemp=2,645 < φcr=1,64); HOMA index increases statistically significantly with increasing severity of the disease: by 14.14% in patients with moderate form compared with patients with mild form, and in the presence of severe form by 28.31% compared with patients with moderate and by 46.46% compared with patients with mild forms of AA (p <0.05); the rate of triglycerides in the blood increases statistically significantly depending on the severity of AA: by 36.17% in patients with moderate form and by 41.78% in patients with severe form compared with mild form of AA (p <0.05); the content of high-density lipoproteins in the blood decreases statistically significantly depending on the severity of AA: by 2.12% in patients with moderate form compared with mild form and by 9.53% in patients with severe form compared with moderate form (p <0.05); no relationship has been found between the severity of MS, given the number of its components, and the stage of AA: active and chronic. Conclusions. As a result of the study, the relationship between the severity of AA and the severity of metabolic disorders in the presence of MS in patients has been established. An important area is the study of correction of dyslipidaemia and insulin resistance in a comprehensive therapy of AA associated with MS.
