The results of epidemiological studies indicate that the majority of patients with T2D do not achieve the targeted parameters of glycemic control on BI in the real-world settings. In this review the results of real-world evidence studies assessing predictors of success or failure of BI therapy in patients with T2D are we summarized. A number of studies have demonstrated that delayed initiation of insulin therapy with a high level of glycated hemoglobin A1c (HbA1c) at the start of the treatment reduces achieving glycemic control targets on BI. Hypoglycemia in the first weeks or months of BI treatment may reduce the adherence and persistence to treatment and likelihood of achieving treatment targets. In real-world evidence studies, glargine 300 U/mL and degludec, the long-acting second-generation insulin analogues, have shown greater potential in reduction of HbA1c levels with a lower risk of hypoglycaemia compared to other BIs. In the DUNE, ATOS, and some others studies, a lack of insulin dose titration in newly initiated BI users and those who needed treatment intensification was demonstrated. Poor treatment adherence and persistence (missed injections, incorrect dose selection, and temporary or permanent discontinuation of insulin therapy), deviations in insulin injection technique, and formation of lipohypertrophy at the injection sites are also common problems that prevent good glycemic control in these patients. Therefore, patient education with a focus on injection technique, dose titration and prevention of hypoglycemia, as well as the use of the second-generation BI analogs, increases the chances for achieving glycemic control targets in patients with T2D who initiate or need to intensify BI therapy.","PeriodicalId":11327,"journal":{"name":"Diabetes Mellitus","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83839757","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}

As a result of multivariate regression analysis of seven significant factors in DM1 and thirteen in DM2 (evaluated by univariate anlisys), a number of the most important predictors of risk for fatal outcome were identified: in DM1 these were age ≥65 years (OR =4.01, 95% CI: 1.42–11.36), presence of arterial hypertension (AH) (OR =2.72, 95% CI: 1.03 -7.16) and diabetic foot syndrome (DFS) (OR = 7.22, 95% CI: 1.98–26.29); for T2DM: age ≥ 65 years (OR =2.53, 95% CI: 1.96–3.27), male (OR =1.51, 95% CI: 1.23–1.84), duration DM ≥10 years (OR =2.01, 95% CI: 1.61–2.51), BMI ≥ 30 kg/m2 (OR =1.26, 95% CI: 1.02–1.55), ASCVD/CKD (OR =1.49, 95% CI: 1.01–2.04), history of diabetic coma (OR =12.97, 95% CI: 1.89–88.99) and presence of disability ( OR =1.40, 95% CI: 1.14–1.73). In T2DM, the type of antidiabetic therapy (ADT) prior to COVID -19 (last visit before the development of infection) had a significant impact: Insulin therapy (OR = 1.64, 95% CI: 1.30–2.07), sulfonylureas (SU) (OR =1.51, 95% CI: 1.23–1.84)); dipeptidyl peptidase-4 inhibitor (iDPP-4) therapy (OR =0.57, 95% CI: 0.39–0.83) and sodium-glucose cotransporter-2 inhibitor (iSGLT2) therapy (OR =0.64, 95% CI: 0.46–0.88).

A retrospective analysis of the database of the national epidemiological cross-sectional study NATION was carried out. Depending on the self-specified nationality, on the basis of anthropological characteristics, the following ethnic groups were identified: “Mongoloid population”, “Peoples of the Volga region”, “Peoples of the North Caucasus”, “Peoples of Transcaucasia”, “Russians”. The analysis consisted of several stages and included: analysis of the anthropometric features of the selected groups, taking into account the presence of carbohydrate metabolism disorders (MO); study of the prevalence of violations of the MA in the selected ethnic groups; analysis of ethnic characteristics of risk factors for the development of type 2 diabetes; analysis of the frequency of violations of the MA in various ethnic groups, taking into account the territory of residence. MR disorders were defined as the presence of DM and/or prediabetes. In accordance with the WHO criteria, HbA1c≥6.5% corresponded to the diagnosis of DM, HbA1c values in the range of 5.7%≤HbA1c<6.5% to the diagnosis of prediabetes.RESULTS: The highest frequency of violations of the MA was observed in the group «Peoples of the Volga region» (31.2%), the lowest in the «Peoples of the North Caucasus» (15.6%).

Chronic kidney disease (CKD) is one of the most common diabetic complications. Kidney injury signs and/or estimated glomerular filtration rate (eGFR) decrease are seen in 40-50% of patients with DM2. Three groups of factors are considered to be the basis of CKD development and progression in DM2: metabolic, hemodynamic, inflammation and fibrosis. Existing drugs that are used in patients with CKD and DM2 first of all target hemodynamic and metabolic disturbances, but their action against inflammation and fibrosis is indirect. Hyperactivation of mineralocorticoid receptors (MR) is considered as one of the main trigger factors of end-organ damage in patients with DM2 due to inflammation and fibrosis. Development of selective nonsteroidal MR antagonists (MRA) as a new class of medications is directed to demonstrate positive effects from blocking this pathophysiological pathway of CKD development and overcome the steroidal MRAs’ shortcomings. Hence pathophysiological hyperactivation of MR with subsequent inflammation and fibrosis in patients with CKD in DM2 is considered a promising therapeutic target for the new drugs with cardionephroprotective effect.","PeriodicalId":11327,"journal":{"name":"Diabetes Mellitus","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82606070","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}

DNOAP is characterized by persistent aseptic inflammation of the bone structures of the foot, which creates significant difficulties in planning therapeutic measures. In the medical literature, there are data demonstrating the role of individual cytokines and neurohumoral factors in the prolongation of the inflammatory process in diabetes, however, there are currently very few studies that determine reliable markers of aseptic inflammation in DNOAP.AIM: To study the effect of neurohumoral factors and advanced glycation end products on the activity of aseptic inflammation in the bone structures of the foot in patients with type 2 diabetes mellitus (DM2) and diabetic neuroosteoarthropathy.MATERIALS AND METHODS. The study included 88 patients with type 2 diabetes (45 men, 43 women). Group 1 consisted of patients with DM2 and inactive DNOAP (n= 43), group 2 (n= 45) consisted of patients with DM2 and distal diabetic neuropathy without osteoarticular pathology. The diagnosis of diabetic neuropathy was based on the analysis of the clinical picture and indicators of peripheral sensitivity. Diagnosis of DNOAP and determination of its stage was based on clinical data, the results of infrared thermometry and radiology tests of the foot bones. General clinical assessment was used, radiology tests (X-ray, MRI), evaluation of CRP, calprotectin, copeptin, glutathione peroxidase 1 (GP1).RESULTS. According to the results of examination and palpation of the feet, as well as the analysis of the temperature gradient of the skin of the affected and contralateral limb (infrared thermometry), DNOAP was detected and the stage of this complication was determined. The diagnosis of the chronic stage of DNOAP was confirmed by the results of MRI and the clinical picture (no difference in skin temperature on the symmetrical areas of the feet). According to the results of laboratory analysis, a statistically significant difference in copeptin values was revealed — in group 1 — 0.232 µg/ml [0.147; 0.342], in group 2 — 0.115 µg/ml [0.065; 0.203] (p>0.05) and CRP — in group 1 — 7.113 mg/l [2.453; 16.505], in group 2 — 2.187 mg/l [1.131; 5.567] (p>0.05), leukocyte levels in the groups did not differ significantly: group 1 — 7.86 [6.40; 9.00]*10^9, group 2 — 7.00 [6.00; 8.15] (p>0.05).

After bariatric interventions of the bypass type, the passage of bile through the gastrointestinal tract, as well as its interaction with food masses, changes significantly, which served as the basis for studying this phenomenon. The information accumulated to date indicates enormous changes occurring not only in the anatomy, but also in the biology of the gastrointestinal tract after bariatric bypass surgery. The composition of the intestinal microbiota and the composition of bile masses undergo significant changes. Most of the works available today suggest that these changes are the cause of a number of metabolic rearrangements, and directly affect carbohydrate metabolism.

The issue of whether there is a need of differential diagnosis between autoimmune DM and non-immune forms of DM raises in cases of preclinical diagnosis of T1D and laboratory remission for more than 6 months.AIM: To study the clinical, immunological, genetic characteristics of T1D remission phase and MODY in children, to determine the diagnostic criteria for T1D and MODY in children.MATERIALS AND METHODS: A single-centre, cross sectional noncontrolled comparative study of two independent cohorts. Data of 150 children examined in the Endocrinology Research Center (January 2016–June 2021). First cohort included patients with complete clinical and laboratory remission of T1D (n=36), second cohort included patients with MODY, confirmed by genetic study (n=114).RESULTS: The median age of diabetes manifestation was significantly higher in patients with T1D — 11.25 years [8.33; 13.78] than in patients with MODY — 7.5 years [4.6; 12.2] (p=0.004). In patients with T1D remission the level of glycated hemoglobin was 6.0% [5.6; 6.4], in group with MODY — 6.5% [6.2; 6.7] (p<0.001). Patients with monogenic diabetes had impaired fasting glucose — 6.27 mmol/l [5.38; 6.72], while patients with remission phase had normoglycemia — 5.12 mmol/l [4.17; 5.87]. The oral glucose tolerance test was perform to all patients, two-hour glucose level did not significantly differ in two groups (p=0.08). A strong family history of diabetes in patients with MODY registered more often (93% vs. 66.7%).
