Background Glucose variability (GV) is considered an important factor for cardiovascular disease (CVD) in patients with type 2 diabetes mellitus (T2DM). High GV causes endothelial dysfunction and increased oxidative stress. Dipeptidyl peptidase-4 (DPP-4) inhibitors may improve endothelial function and decrease GV. The aim of this study was to investigate the effects of vildagliptin, a DPP-4 inhibitor, compared with glibenclamide in GV and endothelial function in patients with T2DM and arterial hypertension. Methods This is a prospective, randomized, open and drug-controlled study. Fifty patients older than 35 years with T2DM and hypertension without CVD were randomized to receive vildagliptin (n=25) or glibenclamide (n=25), both in added-on metformin. Laboratory tests and analysis of endothelial function were performed before and 12 weeks after treatment. Endothelial function, defined by reactive hyperemia index (RHI), was analyzed by peripheral artery tonometry (endo-PAT2000). GV was evaluated by capillary glucose with intermittent monitoring device, six measurements per day, for three days, before and after treatment. The median of standard deviation (SD) of mean blood glucose (MBG) was used to evaluate GV. Results GV decreased in the vildagliptin group (35.2 to 30.7, P =0.037) but did not change with glibenclamide (37.6 to 37.5, P =0.765). Glycated hemoglobin was similar in both groups. MBG decreased only in glibenclamide group, without difference with vildagliptin group ( P =0.374). There were no changes in the RHI in both groups and there was no correlation between GV and RHI ( P =0.658). Conclusion Vildagliptin reduces GV; however, the action on endothelial function was not demonstrated. In addition, there was no correlation between GV and endothelial function.

Сьогодні проблема порушення вуглеводного обміну є однією з найважливіших в ендокринології, що сприяє залученню світовим товариством більшої кількості ресурсів для її вирішення. Огляд присвячено висвітленню та оцінці новітніх показників контролю рівня глюкози в крові, їх інтерпретації та можливості використання в практиці. Наголошується на ролі безперервного моніторингу рівня глюкози (continuous glucose monitoring, CGM) як нового методу дослідження глікемії та його перевагах. Забезпечуючи вимірювання концентрації глюкози в крові майже безперервно протягом кількох днів поспіль, малоінвазивний датчик глюкози зробив революцію в лікуванні цукрового діабету (ЦД) і стає все більш поширеною технологією, особливо для інсулінзалежних пацієнтів. Цілодобове спостереження за ЦД, здійснюване системою контролю рівня глюкози, може спрогнозувати та попереджати гіпо- або гіперглікемію. Час у діапазоні (time in range, TIR) вимірюється за допомогою CGM і повинен використовуватися з іншими показниками, включаючи час нижче діапазону (time below range, TBR), що вказує на гіпоглікемію, і час вище діапазону (time above range, TAR), що вказує на гіперглікемію, адже необхідно враховувати не тільки значення TIR, але й ступінь відхилення від нього (TAR і TBR). Показано, що TIR обернено корелює з ризиком виникнення або прогресування пов’язаних із ЦД мікросудинних ускладнень, таких як діабетична ретинопатія, мікроальбумінурія та периферична нейропатія. У статті також розглянуто недоліки найпопулярніших методів оцінки глікемії, зокрема, за рівнем глікозильованого гемоглобіну (glycated hemoglobin, HbA1c). Цей показник не показує короткочасних відхилень глікемії від цільових значень. Крім того, результати глікемічного контролю за допомогою HbA1c можуть спотворюватися у вагітних та пацієнтів із хворобами крові. Показано взаємозв’язок між показниками CGM із HbA1c та середнім рівнем глюкози в крові: TIR і середній рівень глюкози високо корелюють між собою, але лише помірно — із HbA1c.
The relevance of the study of glycemic variability in patients with diabetes mellitus and diabetic nephropathy is due to disability of the able-bodied population and high mortality against the background of the almost irreversible progression of diabetic nephropathy. The article highlights modern ideas about the influence of various factors on the occurrence of diabetic nephropathy and its course. The article is devoted to a review of current recommendations on diabetes mellitus and diabetic nephropathy; the etiopathogenesis of diabetic nephropathy was described in detail. The role of the kidneys in glucose homeostasis, renal gluconeogenesis, and glucose reabsorption by the kidneys in healthy and in pathology is described. Detailed expositions of glycemic variability parameters, their changes in patients with diabetes mellitus depending on the stage of diabetic kidney damage are presented. The role of the kidneys in maintaining energy homeostasis, impaired glucose homeostasis in conditions of chronic kidney disease is described. We analyzed different options for insulin therapy, their advantages, and disadvantages in patients with diabetes mellitus with diabetic nephropathy. The presented material is extremely relevant for the development and implementation in the clinical practice of glycemic control methods to optimize treatment tactics, prevent the formation of microvascular complications, and early disability of patients with diabetes mellitus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
