BACKGROUND: A decrease in the frequency of amputations due to diabetic foot syndrome (DFS) is one of the parameters that determine the quality of medical care for patients with diabetes mellitus.AIM: Our aim was to study the indicators characterizing medical care for patients with lower limb pathology in diabetes mellitus in St. Petersburg from 2010 to 2021.MATERIALS AND METHODS: Annual reports on the treatment of patients with DFS in city hospitals specializing in the surgical treatment of DFS and in outpatient offices «Diabetic foot» (DFO) from 2010 to 2021 were analyzed.RESULTS: The average number of patients per year admitted to the DFO was 18,527 (34,440 visits). Proportion of patients with foot ulcers — 8,9%, with Charcot’s arthropathy — less than 1%. Before 2020, the frequency of above the foot amputations decreased from 48.3% to 8.6%, hospital mortality — from 11.7 to 5.7%, the number of revascularizations increased from 37 to 642 per year. The increase in operational activity was not accompanied by a decrease in the frequency of amputations (59.3% in 2019). Of all amputations, 11.3% were patients referred from DFO. During the epidemic, the number of visits and patients admitted to the DFO decreased by 27,3% and 31%, respectively. The proportion of foot ulcers and the frequency of amputations have not changed. Inpatient care was characterized by a decrease in operational activity, a decrease in the availability of revascularization, a 2-fold increase in the proportion of high amputations and an increase in hospital mortality from 5.7% in 2019 to 14.9% in 2021.CONCLUSION: An analysis of the statistics of specialized care for patients with DFS over 12 years showed the reduction of the frequency of high amputations, but revealed an increase in the frequency of surgical interventions in DFS against the background of an almost unchanged proportion of amputations in the structure of all operations. Despite significant quantitative indicators, the outpatient service seems to be insufficiently effective in reaching the target population. The negative impact of the epidemic has led to a significant increase in the frequency of high amputations and mortality.

Modern strategies for the treatment of type 2 diabetes mellitus involve the use of pathogenetically based approaches aimed at achieving optimal glycemic control and its long-term retention. Timely and rational use of 9 classes of hypoglycemic drugs, including as part of combination therapy, makes it possible to achieve significant success in diabetes therapy. One of the fundamental principles in the treatment of type 2 diabetes mellitus is the effect on insulin resistance. For this purpose, two groups of drugs are used: biguanides and thiazolidinediones (glitazones). The action of glitazones is directly related to an increase in the sensitivity of insulin-dependent tissues to insulin and a pronounced decrease in hyperinsulinemia in patients with type 2 diabetes. Of particular interest are the pathways of insulin signal transduction, the mechanisms of insulin resistance, and the possibilities of pathogenetic therapy with thiazolidinediones. Pioglitazone is currently the only available member of the thiazolidinedione class in the world, allowing to expand the management of diabetes mellitus by reducing insulin resistance in muscle and adipose tissue and glucose production by the liver. Its use can have a number of pleiotropic effects, including on cardiovascular diseases and non-alcoholic fatty liver disease, which expands the priorities for choosing hypoglycemic therapy in patients with type 2 diabetes at various stages of therapy.

BACKGRAUND: Now the trend of Type 2 Diabetes Mellitus (T2DM) management from glucocentric to cardioprotective approach take place, and it especially relevant for the multiple group of patients with T2DM using Sulphonylurea (SU). Meanwhile the synchronized glucocardiomonitoring allowed to providing the accurate information about the cardiometabolic status of patients with T2DM.AIMS: Using the professional glucocardiomonitoring for T2DM-SU patients to investigate the relation between the glycemic variability, integral glycemic parameters and proarrhythmogenic cardiovascular events and the long-term cardiovascular outcomes.MATERIALS AND METHODS: In the observational (randomised for inclusion of patients) controlled trial the SU-patients with the T2DM duration 9,8±6,6 years were included, whom the professional glucocardiomonitoring had been made during 5 days and then the fatal and non-fatal cardiovascular events had been investigated during 5 years. RESULTS: From 283 patients with T2DM 154 patients (the basic group) used gliclazide (original drug Diabeton MB), 129 patients (the control group) used glibenclamide. The relation between the rising of the glycemic variability and cardiovascular events (the prolongation QT interval, the ST depression (dST), ventricular arrhythmias (VAs)) were demonstrated. At the basic and the control groups the coefficient of variation (CV) was 23,0±8,1 and 30,1±10,7% respectively (p<0,001), TIR-HYPO — 0,8±2,4 and 3,5±5,4% (p<0,001), the number of glycemia differences > 4 mmol/L/hr — 2,3±3,6 and 3,5±4,3 (p=0,010), the minimal glycemia level — 4,6±1,0 and 3,9±1,4 mmol/L (p=0,001). The followed differences of cardiovascular parameters were determined: QTc — 412±24 and 423±28 ms (p=0,001), dST — 0,052 [0; 0,275] and 0,109 [0; 0,422] (ratio, p=0,012), VAs — 2,2 [0; 5,9] and 3,5 [0; 8,3] (cases/pts, p=0,008). The long-term cardiovascular outcomes from the gliclazide and glibenclamide therapy (cases/100 pts-years): the total and cardiovascular death — 0,12 [0; 1,74] and 0,76 [0; 4,62] (p=0,062), cardiovascular death -0,12 [0; 1,74] and 0,62 [0; 4,08] (p=0,122), myocardial infarction — 1,56 [0; 6,94] and 2,00 [0; 8,02] (p=0,193), stroke — 0,78 [0; 4,66] and 0,76 [0; 4,62] (p=0,169), chronic heart failure — 0,52 [0; 3,72] and 1,24 [0; 6,06] (p=0,095), MACE — 2,46 [0; 10,1] и 2,62 [0; 9,38] (p=0,095), severe hypoglycemia at home — 2,46 [0; 9,12] и 7,24 [0; 16,68] (p<0,001).CONCLUSIONS: It was demonstrated that the gliclazide (original drug Diabeton MB) administration is characterized with the better quality of glycemia control, the lower glycemic variability, the lower frequency of the SU-associated hypoglycemia, dST, VAs, the lower prolongation QTc interval. The implementation of the synchronized glucocardiomonitoring is necessary for minimization of the cardiovascular T2DM-complications and for the choice of the personalized

BACKGROUND: Male hypogonadism is associated with type 2 diabetes mellitus (T2DM), therefore, it is of interest to study its frequency. The clinical symptoms of hypogonadism are not specific, and laboratory diagnostics is the basis for its detection. The optimal method for this diagnostics is isotope dilution liquid chromatography/tandem mass spectrometry, which was used in our study. AIMS: Assessment of the incidence and aggravating factors of male hypogonadism in type 2 diabetesMATERIALS AND METHODS: A full-design, cross-sectional, screening, single-center, non-interventional study included men with T2DM, who were he was treated in Endocrinology Research Centre, Moscow. The study was conducted from October 2021 to January 2022. Medical history assessment, physical examination with determination of body mass index (BMI), measurement estimation of total testosterone by isotope dilution liquid chromatography/tandem mass spectrometry, glycated hemoglobin (HbA1c) and lipid profiles were performed. The groups were compared using the Mann-Whitney U-test for quantitative indicators and χ² with Yates’ correction for qualitative ones. Differences were considered statistically significant with p0,05.RESULTS: Hypogonadism was detected in 355 (70.3%) men with T2DM. Patients with hypogonadism had statistically significantly higher BMI, worse glycemic control, lower HDL levels, and higher triglycerides than eugonadal men. An additional comparative analysis among non-obese individuals showed the presence of statistically significant differences in the level of HbA1c (higher in hypogonadal men) and HDL (lower in hypogonadal men). An analysis of hypogonadal patients depending on the presence of obesity showed statistically significant differences between groups in the level of total testosterone (lower in obese men) and triglycerides (higher in obese men).CONCLUSIONS: The prevalence of male hypogonadism in type 2 diabetes was 70,3%. Its development was associated with obesity and poor glycemic control.

There are quite a lot of scientific works today dedicated to the role of disorders carbohydrate metabolism (DCM) in the development of end-stage renal disease (ESRD), at the same time, the influence of chronic kidney disease (CKD) on the development of carbohydrate disorders remains insufficiently studied, especially in patients on renal replacement therapy (RRT). The annual steady increase in the number of patients with ESRD without diabetes mellitus (DM) requiring dialysis therapy leads to increased interest and the need to study carbohydrate status in these patients. It is known that hyperglycemia in patients without DM on hemodialysis (HD) is a predisposing factor to the development of cardiovascular accidents that worsen the quality of life and also increase mortality. The peculiarities of glucose metabolism in patients receiving RRT do not always allow adequate assessment of carbohydrate status using glycated hemoglobin (HbA1c). The review provides up-to-date information on the prevalence of DCM in patients with ESRD without DM receiving HD RRT, touches upon the peculiarities of glucose metabolism, interpretation of HbA1c and glycated albumin values, and mortality risk in hemodialysis patients with various DCM.

Diabetes of both type 1 and type 2 is characterized by a progressive loss of β-cell mass, which contributes to the disruption of glucose homeostasis. The optimal antidiabetic therapy would be simple replacement of lost cells, but at present, many researchers have shown that the pancreas (PZ) of adults has a limited regenerative potential. In this regard, significant efforts of researchers are directed to methods of inducing the proliferation of β-cells, stimulating the formation of β-cells from alternative endogenous sources and/or the generation of β-cells from pluripotent stem cells. Factors that regulate β-cell regeneration under physiological or pathological conditions, such as mediators, transcription factors, signaling pathways and potential pharmaceuticals, are also being intensively studied. In this review, we consider recent scientific studies carried out in the field of studying the development and regeneration of insulin-producing cells obtained from exogenous and endogenous sources and their use in the treatment of diabetes. The literature search while writing this review was carried out using the databases of the RSIC, CyberLeninka, Scopus, Web of Science, MedLine, PubMed for the period from 2005 to 2021. using the following keywords: diabetes mellitus, pancreas, regeneration, β-cells, stem cells, diabetes therapy.
1型和2型糖尿病的特点是β细胞质量的进行性损失，这有助于破坏葡萄糖稳态。最佳的抗糖尿病治疗方法是简单地替换失去的细胞，但目前，许多研究人员已经表明，成人的胰腺(PZ)具有有限的再生潜力。在这方面，研究人员的重大努力是针对诱导β细胞增殖的方法，刺激从其他内源性来源形成β细胞和/或从多能干细胞产生β细胞。在生理或病理条件下调节β细胞再生的因子，如介质、转录因子、信号通路和潜在的药物，也正在被深入研究。在这篇综述中，我们考虑了最近在研究外源性和内源性胰岛素生成细胞的发育和再生及其在糖尿病治疗中的应用方面所进行的科学研究。在撰写本综述时，使用RSIC、CyberLeninka、Scopus、Web of Science、MedLine、PubMed等数据库进行了2005年至2021年的文献检索。使用以下关键词:糖尿病，胰腺，再生，β细胞，干细胞，糖尿病治疗。

Obesity and associated metabolic diseases are often accompanied by changes in the gut microbiota leading to metagenome gene diversity decrease. Fecal microbiota transplantation (FMT) is one of the most effective methods for correcting the intestinal microflora. FMT obtained from healthy donors has been proven to be an effective treatment of infections caused by Clostridium difficile. The use of FMT for correction of metabolic disorders is promising, however, data on its application is limited and has contradictory results. In our work, two patients (siblings) presented with obesity grade II and various types of diabetes mellitus (DM): the older brother (44 years old) with diabetes mellitus type 2 (DM 2), a younger brother (39 years old) with diabetes mellitus type 1 (DM 1). Both patients underwent FMT as part of complex antidiabetic therapy. During the course of treatment, a decrease in body weight was noted in both patients (4–5 kg for the first month of observation, then -1–2 kg per month). One year after FMT, a patient with type 2 diabetes showed a decrease in the severity of insulin resistance (IR), measured by the hyperinsulinemic euglycemic clamp test (initial M-index 2.42 mg/kg*min, after 1 year — 3.83 mg/kg* min) as well as the maintenance of satisfactory carbohydrate metabolism compensation against the diminishing the hypoglycemic therapy. In a patient with DM 1, no significant dynamics of carbohydrate exchange indices, including detected glycated hemoglobin (HbA1c), insulin dose and IR were during the observation period. Metagenomic sequencing of stool samples (n = 20) collected from both patients before and within 1 year after FMT showed no significant changes in the taxonomic profile of the microbiota at the level of microbial families. Metabolomic analysis of the composition of feces showed no directed changes in the composition of metabolites after the FMT procedure, the nature of changes within the samples from each patient during the entire study period was random. Thus, FMT had no effect on the course of DM1, but served as a starting point for weight loss and improvement glucose profile in DM2. However, convincing data confirming a causal correlation between FMT and improvement in the course of T2DM have not been obtained.

Fecal microbiota transplantation (FMT) is one of the most effective methods for correcting the intestinal microflora. FMT obtained from healthy donors has been proven to be an effective treatment of infections caused by Clostridium difficile. The use of FMT for correction of metabolic disorders is promising, however, data on its application is limited and has contradictory results. In our work, two patients (siblings) presented with obesity grade II and various types of diabetes mellitus (DM): the older brother (44 years old) with diabetes mellitus type 2 (DM 2), a younger brother (39 years old) with diabetes mellitus type 1 (DM 1). Both patients underwent FMT as part of complex antidiabetic therapy. During the course of treatment, a decrease in body weight was noted in both patients (4–5 kg for the first month of observation, then -1–2 kg per month). One year after FMT, a patient with type 2 diabetes showed a decrease in the severity of insulin resistance (IR), measured by the hyperinsulinemic euglycemic clamp test (initial M-index 2.42 mg/kg*min, after 1 year — 3.83 mg/kg* min) as well as the maintenance of satisfactory carbohydrate metabolism compensation against the diminishing the hypoglycemic therapy. In a patient with DM 1, no significant dynamics of carbohydrate exchange indices, including detected glycated hemoglobin (HbA1c), insulin dose and IR were during the observation period. Metagenomic sequencing of stool samples (n = 20) collected from both patients before and within 1 year after FMT showed no significant changes in the taxonomic profile of the microbiota at the level of microbial families. Metabolomic analysis of the composition of feces showed no directed changes in the composition of metabolites after the FMT procedure, the nature of changes within the samples from each patient during the entire study period was random. Thus, FMT had no effect on the course of DM1, but served as a starting point for weight loss and improvement glucose profile in DM2. However, convincing data confirming a causal correlation between FMT and improvement in the course of T2DM have not been obtained.","PeriodicalId":73708,"journal":{"name":"Journal of diabetes mellitus","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88326883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BACKGROUND: Osteomyelitis in diabetic osteoarthropathy occurs in 65 % of cases, and it is the main cause of non-traumatic amputations. The choice of optimal treatment technologies should be based on understanding the pathogenetic characteristics of this disease.AIM: To study the pathomorphological and pathochemical picture of osteomyelitic focus in patients with diabetic neuroosteoarthropathy.MATERIALS AND METHODS: Object — 20 patients (55.3±9.33 years) with Type 2 diabetes mellitus, diabetic neuroosteoarthropathy, chronic osteomyelitis of the foot bones. The treatment consisted in surgical debridement of the purulent focus with the material collection for pathomorphological and biochemical studies, and in reposition and alignment of bone fragments with the leg and foot fixation using the Ilizarov fixator in order to form bone ankylosis of the compromised joint.RESULTS: Subacute and acute course of chronic osteomyelitis was registered in 80 % of cases. As for the pathohistological changes in bone tissue, the following ones were the most significant: necrosis and the presence of an inflammatory infiltrate of varying severity depending on the phase of the inflammatory process. The articular cartilage structure was broken in all the cases. Activation of osteoclasts was observed in the osteomyelitis focus, especially in the subchondral zone. There was no subchondral bone plate in most cases, or only its fragments remained. Pathohistological examination of the soft tissues associated with the osteomyelitis focus indicated the presence of mirocirculatory and denervation disorders due to necrosis and hyalinosis of a significant part of microvessels against the background of compensatory hypervascularisation and chronic inflammation, narrowing and obliteration of the lumens of feeding arteries, almost complete absence of nerve elements in the tissues or their destructive changes. An increase in the activity of lytic enzymes was revealed in the interstitial environment of the tissues surrounding the osteomyelitis focus (138-fold increase in the activity of acid phosphatase, interstitial osteolytic index was 7.2-fold higher than blood serum index).CONCLUSION: The pathomorphological signs of chronic osteomyelitis subacute and acute processing were observed in most patients. Breaking the articular cartilage structure was accompanied by invasion of vessels, inflammatory infiltrate, and by activation of osteoclasts in the subchondral zone. Destructive changes of vessels and nerves in the soft tissues associated with the osteomyelitis focus can be etiopathogenetic factors of this disease development. The technologies for stopping this process should be based on obligatory debridement of the focus with sequestrnecrectomy, with regular monitoring of the operated segment condition.

BACKGROUND: Biliopancreatic diversion (BPD), and its modifications, is the most effective surgical bariatric treatment of morbid obesity and associated metabolic disturbances. However, at present comparative studies of the dynamics of carbohydrate metabolism after various modifications of the BPD are lacking.AIM: comparative assessment for the effectiveness of biliopancreatic diversion with duodenal switch (BPD-DS) in the HessMarceau and single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) modifications for correcting carbohydrate metabolism disorders and achieving remission of Diabetes mellitus type 2 (DM2) within a period of up to five years after both operations.MATERIALS AND METHODS: within the framework of a prospective study, 200 patients with morbid obesity were operated on using the BPD-DS (group 1, n = 100) and SADI (group 2, n = 100) methods, the dynamics of clinical and laboratory parameters was analyzed in groups depending on the presence, or absence, of DM2, with an emphasis on the analysis of indicators of carbohydrate metabolism. DM2 was diagnosed in 35 (35.0%) patients in group 1 (BPD - DS) and 45 (45.0%) in group 2 (SADI). All patients underwent a standard set of clinical, laboratory and instrumental examination methods before, immediately after and at 3, 6, 9, 12, 18, 24, 36, 48 and 60 months after the operation.RESULTS: 5 years after the operation, complete remission of DM2 was achieved in 38 (84.4%) and 32 (91.4%) patients from the SADI and BPD-DS groups, respectively, and 7 (15.6%) and 3 (8.6 %) of patients achieved partial remission. The level of C-peptide, which also decreased after both modifications of BPS, was higher in patients after BPS in the SADI modification, both in patients with DM2 36 months (p<0.05), and in patients without DM2 at 3, 12 and 24 months after surgery (p<0.05).CONCLUSION: The frequency of achieving stable remission of DM2 is comparable in both groups. The carbohydrate profile of patients after SADI is characterized by higher levels of glucose and C-peptide compared to BPD-DS at different periods of follow-up over five years.

BACKGROUND: Psychological predictors of overall mortality in the Russian population of Type 2 diabetic patients and their impact compared to biological risk factors have not been studied.AIM. To identify clinical, laboratory and psychological factors independently associated with the 5-year overall mortality in Type 2 diabetic patients in the Moscow region.MATERIALS AND METHODS: This open label observational prospective study included 178 consecutive type 2 diabetic patients (women 145, men 33, age range 37 to 82 years, duration of diabetes 0,5 to 30 years). At baseline, in addition to the standard clinical, laboratory and instrumental work-up, all patients were assessed for depression, cognitive dysfunction and diabetes-related quality of life. No study-related intervention was performed; all patients were followed up and treated by their local physicians. After 5 years, we assessed the patients’ vital status (alive or dead). Multiple logistic regression was used to identify baseline patients’ characteristics, which were significantly and independently associated with 5-year overall mortality. Taking into account the exploratory type of multiple regression, the results were considered significant at α<0.1.RESULTS: At 5 years, 150 (84%) patients were alive and 15 (8,4%) were dead; no information could be obtained for the rest 13 (7,3%) patients. The analysis of 165 patients with the verified outcome, independent and significant associations with the death outcome were found for male gender (odds ratio [OR] 6,36 [95%CI 0,91–44.40]; p=0.06), age (OR 2.06 [1.30–3.27]; p<0.002), chronic heart failure (CHF) (OR 2.78 [1.25–6.2]; р=0.012), Hamilton depression scale score (OR 1,18 [1.03–1.34]; р=0.016), cognitive dysfunction score (Roschina scale) (OR 1.20 [1.05–1.35]; р=0.006), and age — body mass index interaction (OR 0,98 [0,97–0,997]; р = 0,013). The predicted probability of death within the next 5 years in men and women was 22,9% and 6,7%, respectively. The highest score of cognitive dysfunction was associated with a 25% predicted probability of death and the lowest, with a 2% probability of death; predicted probabilities of death for the highest and lowest depression scores were 26% and 2%, respectively. The 5-year predicted probability of death in the patients without CHF was 6,7%, with CHF I NYHA functional class, 9,8%, II functional class 13,6%, III functional class 18,2%, and IV functional class 23,5%. All other baseline clinical, laboratory, demographic, psychological and socioeconomic variables were not significantly associated with the 5-year survival rate. The model was not verified on an external cohort.CONCLUSION: Cognitive dysfunction and depression have a significant negative impact on the 5-year mortality rate at much higher degree, than glycemic control, any diabetes-related complications and cardiovascular disorders, excluding CHF.
