Background: Investigating the inflammatory status and iron metabolism in patients with impaired carbohydrate metabolism seems quite relevant, while only few studies are devoted to the relationship between metabolic parameters, including lipid profile, inflammatory status indicators and the state of ferrokinetics in diabetes mellitus types 1 and 2 in a comparative aspect.Aims: To establish the direction of changes in the inflammatory status and the state of ferrokinetics in patients with type 1 and type 2 diabetes mellitus depending on lipid metabolism disorders.Materials and methods: The study included 48 patients with type 1 diabetes, 81 patients with type 2 diabetes; 11 people with obesity without impaired carbohydrate metabolism made up the comparison group, 17 healthy volunteers - the control group. Low-grade inflammation was assessed by the levels of high-sensitive C-reactive protein (CRP), tumor necrosisfactor-а (TNF-а), ferritin, and erythrocyte sedimentation rate (ESR). The state of iron metabolism was evaluated by the main hematological parameters (hemoglobin, red blood cell count, hematocrit), serum iron concentrations, transferrin, ferritin and hepcidin concentrations. In all patients lipid metabolism parameters, glycated hemoglobin, and microalbuminuria were measured.Results: Patients with type 1 and type 2 diabetes mellitus had significantly higher inflammatory markers concentrations-TNF-а, ESR, and CRP - in relation to obese patients without impaired carbohydrate metabolism and those in the control group. The highest production of TNF-а was observed in patients with type 1 diabetes mellitus (15.28 [12.41-24.41] pg/ml), whereas CRP (7.00 [3.00-11.85] ng/ml) and ESR (18.00 [9.00-27.00] mm/h) were higher in patients with type 2 diabetes. In the structure of the examined individuals with diabetes mellitus (regardless of its type), dyslipidemia type IIb in comparison with less atherogenic type IIa dyslipidemia was characterized by a higher production of CRP (6.9 [3.00-12.35] and 3.00 [1.80-8.70] ng/ml, respectively), ESR (20.00 [10.00-30.00] and 15.00 [5.00-24.50] mm/h, respectively) and ferritin (114.80 [48.90-196.45] and 50.90 [19.58-114.10] ng/ml, respectively). Compared to iron deficiency anemia, anemia of chronic diseases in diabetes mellitus patients was more often accompanied by dyslipidemia llb (χ2=2.743; p=0.098) and was characterized by a higher content of atherogenic fractions of cholesterol.Conclusions: Patients with type 2 diabetes mellitus and a more atherogenic dyslipidemia profile (type IIb) have a phenotype of the local inflammatory mesenchymal reaction of the liver with an increase in acute-phase proteins predominantly of hepatic origin (CRP, ferritin), whereas individuals suffering from type 1 diabetes and less atherogenic lipid profile (type IIa) have a phenotype of an autoimmune, genetically determined inflammatory response. It has been established that anemia of chronic diseases developing in the background of diabetes mellitus is associated with a more atherogenic lipid profile, compared with iron deficiency anemia.

This study aims to establish relationships between inflammatory status, ferrokinetics and lipid metabolism in patients with diabetes mellitus. Subclinical inflammation was assessed by levels of high-sensitive C-reactive protein, tumor necrosis factor-α and erythrocyte sedimentation rate. Iron metabolism parameters included complete blood count, serum iron, transferrin and ferritin. Metabolic status assessment included lipid profile, glycated hemoglobin and microalbuminuria measurement. As a result of the study it was possible to establish both general (universal) and diabetes mellitus (DM) type-dependent relationships between the parameters of lipid profile and metabolic control in DM. High-density lipoprotein cholesterol (HDL-C) levels negatively correlated with microalbuminuria (r = −0.293; p ˂ 0.05 for type 1 diabetes and r = −0.272; p ˂ 0.05 for type 2 diabetes). Ferritin concentration positively correlated with triglyceride level (r = 0.346; p ˂ 0.05 for type 1 diabetes and r = 0.244; p ˂ 0.05 for type 2 diabetes). In type 1 diabetes, a negative correlation was discovered between estimated glomerular filtration rate (eGFR) and LDL-C (r = −0.480; p ˂ 0.05), very low-density-lipoprotein cholesterol (VLDL-C) (r = −0.490; p ˂ 0.05) and triglycerides (r = −0.553; p ˂ 0.05), and a positive one between C-reactive protein concentration and triglyceride level (r = 0.567; p ˂ 0.05). Discovered relationships between lipid profile indices, inflammatory status and microalbuminuria confirmed mutual influence of hyperlipidemia, inflammation and nephropathy in diabetes patients. Obtained results justify the strategy of early hypolipidemic therapy in patients with diabetes mellitus to prevent the development and progression of microvascular complications.

BACKGROUND: It is known that metabolic disorders in diabetes mellitus have a regulating effect on ferrokinetics, and therefore diabetes mellitus is often accompanied by various disorders of iron metabolism, both anemia and secondary iron overload. The main problem is timely and accurate differential diagnosis between anemia of chronic diseases and iron deficiency anemia. It is necessary to establish reliable laboratory markers of anemia of chronic diseases in order to solve this problem, as well as to understand what metabolic disorders can lead to the occurrence and aggravate the course of this type of anemia. AIMS: To study the frequency of occurrence of violations of ferrokinetics in patients with diabetes mellitus, as well as to establish clinical and biochemical correlations that are significant in the differential diagnosis of various disorders of iron metabolism: iron deficiency anemia, anemia of chronic diseases and dysmetabolic iron overload syndrome in diabetes mellitus. MATERIALS AND METHODS: The research design a single-stage observational single-center research. The research was conducted on the basis of the endocrinological clinic of the Federal State Budgetary Educational Institution of Higher Education Siberian State Medical University in Tomsk. The research included 76 patients with type 1 and type 2 diabetes mellitus. We conducted an assessment of all patients as follows: anthropometric data assessment; glycated hemoglobin study; creatinine level study with the calculation of glomerular filtration rate (GFR) using the CKD-EPI formula. We also evaluated the number of erythrocytes, reticulocytes, the hemoglobin concentration, haematocrit level and biochemical parameters of iron metabolism: serum iron and ferritin concentrations; the concentration of hepsidin and non-specific markers of inflammation: erythrocyte sedimentation rate (ESR) and highly sensitive C-reactive protein (CRP). RESULTS: 20 people (26.3%) of the 76 patients included in the study, had type 1 diabetes mellitus and 56 people (73.3%) had type 2 diabetes mellitus. The parameters of ferrokinetics did not significantly differ in patients with type 1 and type 2 diabetes mellitus, while in the group of patients with 20 patients (26.3%) from the 76 ones included into the research had type 1 diabetes mellitus and 56 (73.3%) from them had type 2 diabetes mellitus. The parameters of ferrokinetics did not significantly differ in patients with type 1 and type 2 diabetes mellitus, while in the group of patients with type 2 diabetes mellitus, the levels of CRP (p=0.034) and blood leukocytes (p=0.020) were significantly higher than in patients with type 1 diabetes mellitus. Both in the main group of patients with impaired carbohydrate metabolism, and in patients with type 2 diabetes mellitus, anemia of chronic diseases prevailed in the structure of the anemia syndrome. After dividing the main group of patients into groups by type of anemia syndrome: absence of anemia, anemia of chronic diseases and iron deficiency anemia, a comparative analysis of the average values of markers of inflammation and the level of hepsidin in these groups was performed. It was found that in patients with anemia of chronic diseases, the level of hepsidin is significantly higher than in patients without anemic syndrome (p=0.033). Paired correlation analysis showed a positive correlation of ESR with microalbuminuria (r=0.515; P0.0001), creatinine level (r=0.467; P0.0001) and negative with GFR (r= -0.436; P0.0001) and iron in serum (r=-0.276; p=0.017). As the result of ROC analysis the most informative in the diagnosis of anemia of chronic disease were: ferritin sensitivity 78%, specificity 52% with a diagnostic threshold of 75.5 ng/ml (area under the curve 0,695; p=0.006); ESR sensitivity 67%, specificity 64% with a diagnostic threshold of 15.5 mm/HR (area under the curve of 0.750 in; p=0.040) and the CRP sensitivity 67%, specificity 64% with a diagnostic threshold of 5.2 ng/ml (area under the curve 0,646; р0.0001). CONCLUSION: Thus, the studied markers of inflammation ESR and CRP, as well as hepsidin in combination with the classic diagnostic parameter ferritin, demonstrated high value in the diagnosis of anemia of chronic diseases and can be included in the modified algorithm for differential diagnosis of anemia syndrome in patients with diabetes mellitus.

Background: The prevalence of diabetes mellitus and its associated complications such as peripheral artery disease is increasing worldwide. We aimed to explore the distinct impact of type 1 diabetes mellitus and type 2 diabetes mellitus on treatment and on short- and long-term outcome in patients with peripheral artery disease. Methods: Retrospective analysis of anonymized data of hospitalized patients covered by a large German health insurance. Assessment of patient’s characteristics (comorbidities, complications, etc.) and outcome using multivariable Cox regression and Kaplan–Meier curves. Results: Among 41,702 patients with peripheral artery disease, 339 (0.8%) had type 1 diabetes mellitus and 13,151 (31.5%) had type 2 diabetes mellitus. Patients with diabetes mellitus had more comorbidities and complications than patients without diabetes mellitus ( p < 0.001). Type 1 diabetes mellitus patients exhibited the highest risk for limb amputation at 4-year follow-up (44.6% vs 35.1%, p < 0.001), while type 2 diabetes mellitus patients had higher mortality than type 1 diabetes mellitus (43.6% vs 31.0%, p < 0.001). Conclusion: Although the fraction of type 1 diabetes mellitus among patients with peripheral artery disease and diabetes mellitus is low, it represents a subset of patients being at particular high risk for limb amputation. Research focused on elaborating the determinants of limb amputation and mortality in peripheral artery disease patients with diabetes mellitus is warranted to improve the poor prognosis of these patients.

The aim of this study was to evaluate the effects of flash glucose monitoring on dietary variety, physical activity, and self-care behavior in patients with diabetes. This study included outpatients with diabetes using insulin who presented at the Department of Diabetes and Metabolism of the Ise Red Cross Hospital. Before initiating flash glucose monitoring and 12 weeks after its initiation, blood glucose-related parameters were assessed and self-administered questionnaires were completed (Dietary Variety Score (DVS), the International Physical Activity Questionnaire (IPAQ), the Summary of Diabetes Self-Care Activities Measure (SDSCA), and the Diabetes Treatment Satisfaction Questionnaire (DTSQ)) and compared between the two time points. We analyzed 42 patients with type 1 diabetes mellitus and 48 patients with type 2 diabetes mellitus. In patients with type 2 diabetes mellitus, but not type 1 diabetes mellitus, there was an increase in moderate/high category scores for IPAQ (P<0.001) and for treatment satisfaction reported via DTSQ. Furthermore, in patients with type 2 diabetes mellitus, the glycemic excursion index improved significantly and HbA1c decreased significantly (from 7.7 (1.2) to 7.4 (0.8), P=0.025). Results showed that standard deviation and mean amplitude of glycemic excursions significantly decreased in patients with type 1 diabetes mellitus (from 71.2 (20.4) to 66.2 (17.5), P=0.033 and from 124.6 (31.9) to 108.1 (28.4), P<0.001, respectively). Flash glucose monitoring is a useful tool to improve physical activity in patients with type 2 diabetes.
