Comparative evaluation of the influence of diabetic retinopathy progression factors on indices of lipid metabolism in metabolic syndrome
Background. The search and study of new risk factors for the development and progression of diabetic retinopathy (DRP) and their modifying influence on the components of metabolic syndrome in type 2 diabetes mellitus (T2DM) remain relevant. The purpose was to conduct a comparative evaluation of the impact of certain DRP development factors on indices of lipid metabolism in metabolic syndrome. Materials and methods. The research was carried out in 64 patients (95 eyes) with T2DM, metabolic syndrome and DRP (males and females, average age 61.55 ± 2.37 years, average duration of diabetes 11.23 ± 2.11 years, average level of HbA1c 9.89 ± 0.78 %, average body mass index 34.55 ± 3.75 kg/m2), who were divided into 3 groups depending on the stage of DRP. Results. Results had showed that the following factors have modifying influence on the level of total cholesterol in the blood of patients with T2DM and DRP: age of patients (under 60 years), duration of diabetes (less than 10 years), decompensation of carbohydrates metabolism — for the 3rd stage of DRP, features of therapy for T2DM (oral hypoglycemic drugs) — for the 2nd stage of DRP; on the level of low-density lipoprotein cholesterol: younger age of patients, decompensation of diabetes — for the 3rd stage of DRP, features of hypoglycemic therapy (insulin therapy), shorter duration of diabetes — for the 2nd stage of DRP; on the level of triglycerides: age of patients (under 60 years), duration of diabetes (less than 10 years) and insulin therapy — for the 1st and 3rd stages of DRP. Conclusions. It is concluded that features of hypoglycemic therapy can be a new modifying factor for the risk of DRP progression.
