Abstract Background and Aims According to various research, vascular complications of type 2 diabetes mellitus are the main reason for patients' mortality. The most specific one, observed in patients with diabetes only, is diabetic microangiopathy, especially diabetic nephropathy. This complication accounts for more than 20% of cases of chronic kidney disease. So, the development of non-invasive methods for the diagnosis of vascular complications of type 2 diabetes mellitus is critically important. There is a perspective method for this problem - Laser Doppler flowmetry (LDF). It is currently used in the diagnosis of diabetic microangiopathy, but the limiting factor is the lack of a unified algorithmic approach to the data interpretation. This work aimed to analyze changes in the amplitude indicators of the low-frequency part of the LDF signal spectrum in patients with chronic kidney disease and type 2 diabetes and to identify their correlations with the glomerular filtration rate. Method The study included 42 patients (20 men and 22 women) with type 2 diabetes mellitus chronic kidney disease (stage C3-C4). The age of patients was 58-77 years (66 years on average). The duration of diabetes was more than 5 years (on average 7 years). All patients had diabetic nephropathy with a decrease in glomerular filtration rate, chronic kidney disease stage C3-C4. Laser Doppler flowmetry was done using the "LAZMA MC-1" system ("Lazma", Russia). Each patient had a 10-minute LDF registration. The sensor was placed on the skin of the rear of the foot. After recording the LDF curve, the special software has calculated amplitudes of endothelial, myogenic, neurogenic, respiratory, and pulse flux motions. Then we assessed the amplitude contribution of every frequency range to the total power of the local flux motion region. The next step was a correlation analysis with the estimated glomerular filtration rate. For statistical analysis, we used the GraphPad Prism 8 (GraphPad Software, USA). Results All examined patients had amplitude peaks in the neurogenic, myogenic, respiratory, and pulse ranges. There were no significant correlations between the glomerular filtration rate and the amplitudes of myogenic and neurogenic flux motions (p>0.05) (Fig. 1). However, there was a significant positive correlation between the contribution of myogenic flux motions to the low-frequency range and glomerular filtration rate (p<0.01), and a negative one – for the contribution of neurogenic flux motions (p<0.01) (Fig. 2). In six observations there was a tendency to a decrease in the contribution of endothelial flux motions as the glomerular filtration rate decreased. Conclusion The results of this study showed that laser Doppler flowmetry has the potential to diagnosis the nature of the dysfunction of individual microcirculation modulation mechanisms. In patients with chronic kidney disease of the C3-C4 stage decreasing the glomerular filtration rate correlated with decreasing the contribution of myogenic flux motions and increasing the contribution of neurogenic flux motions to the total power of the low-frequency part of the LDF signal amplitude-frequency spectrum. These changes can be explained within the framework of the existing understanding of the pathogenesis of diabetic microangiopathy, namely, damage to the smooth muscle layer of the wall of arterioles and venules with damage to myocyte pacemakers and changes of basal vascular tone pattern. It causes an increase in the role of neurogenic modulation of the micro-vascular bloodstream. These data can be an additional argument in favor of the further development of improving laser Doppler flowmetry using for the tasks of early (preclinical) non-invasive diagnosis of microvascular disorders in patients with type 2 diabetes mellitus, as well as for monitoring the effectiveness of the therapy. The reported study was funded by RFBR, project number 19-315-90080.

Chronic kidney disease is a pressing issue for healthcare systems over the world; its prevalence has reached 13% in Western countries. In recent years, cystatin C has been proposed as a more reliable endogenous marker of renal function, especially for the diagnosis of initial changes in glomerular filtration rate. The aim of this study is to analyze the signs of chronic kidney disease in patients with type 2 diabetes mellitus depending on the level of uricemia by using cystatin C in real clinical practice. The study included 127 patients with type 2 diabetes mellitus (mean age = 60.0 years [52.0; 66.0]; sex ratio: 55 men/ 72 women) who received oral hypoglycemic therapy. All subjects, depending on the stage of diabetic nephropathy were divided into groups: group 1 (n=80) included patients with asymptomatic diabetic nephropathy (normoalbuminuria below 30 mg/day)); group 2 (n=22) involved patients with microalbuminuria (30-300 mg/day); group 3 (n=17) included patients with proteinuria; group 4 (n=8) comprised patients with chronic renal failure. Glomerular filtration rate was calculated according to the formulas of Chronic Kidney Disease Epidemiology Collaboration taking into account the concentration of cystatin C (Chronic Kidney Disease Epidemiology Collaboration cys), by Cockcroft-Gault and Modification of Diet in Renal Disease Study using a calculator of the National Institute of Diabetes and Digestive and Kidney Diseases. In patients with type 2 diabetes mellitus, the development of chronic kidney disease is also predetermined by the following comorbid conditions as hypertension, chronic pyelonephritis, hyperuricemia, and asymptomatic urolithiasis, along with diabetic nephropathy. Glomerular filtration rate values in patients with type 2 diabetes mellitus assessed by Chronic Kidney Disease Epidemiology Collaboration cys are more reliable than those assessed by using the formulas of Cockcroft-Gault and Modification of Diet in Renal Disease Study, especially at the limit level of glomerular filtration rate ˂60 ml/min/1.73m2. In patients with type 2 diabetes mellitus, the level of circulating cystatin C is associated with body mass index, waist circumference, blood uric acid concentration and albuminuria levels. The blood concentration of cystatin C in the patients with type 2 diabetes mellitus is determined by the blood concentration of creatine and uric acid.

Although the important role of fibroblast growth factor (FGF)23 on cardiac remodeling has been suggested in advanced chronic kidney disease (CKD), little is known about serum (s)FGF23 levels in patients with heart failure (HF) due to nonischemic cardiac disease (NICD) and early CKD. The present study aimed to investigate sFGF23 levels in NICD patients and identify the responsible factors for the elevation of sFGF23 levels. We prospectively measured sFGF23 levels in consecutive hospitalized NICD patients with early CKD (estimated glomerular filtration rate ≥ 40 ml·min−1·1.73 m−2) and analyzed the data of both echocardiography and right heart catheterization. Of the 156 NICD patients (estimated glomerular filtration rate range: 41–128 ml·min−1·1.73 m−2), the most severe HF symptom (New York Heart Association class III-IV, 53% vs. 33%, P = 0.015) was found in the above median sFGF23 (39.1 pg/ml) group compared with the below median sFGF23 group. sFGF23 levels were higher in patients with HF hospitalization history compared with those without HF [median: 46.8 (interquartile range: 38.8–62.7) vs. 34.7 (interquartile range: 29.6–42.4) pg/ml, P < 0.0001]. In the multivariate analysis, HF hospitalization was independently related to elevated sFGF23 levels ( P = 0.022). Both systolic dysfunction and high plasma aldosterone concentration were identified as predictors of high sFGF23 levels ( P < 0.05). Among the neurohormonal parameters, elevated sFGF23 levels were the only factor to predict a declining left ventricular ejection fraction ( P = 0.001). These findings suggest that the progression of HF per se contributes to the elevation of sFGF23 levels even in the early stages of CKD, which leads to further myocardial dysfunction, potentially creating a vicious cycle.
