Recently, it has been argued that obesity leads to a chronic pro-inflammatory state that can accelerate immunosenescence, predisposing to the early acquisition of an immune risk profile and health problems related to immunity in adulthood. In this sense, the present study aimed to verify, in circulating leukocytes, the gene expression of markers related to early immunosenescence associated with obesity and its possible relationships with the physical fitness in obese adults with type 2 diabetes or without associated comorbidities. The sample consisted of middle-aged obese individuals (body mass index (BMI) between 30-35 kg/m²) with type 2 diabetes mellitus (OBD; n = 17) or without associated comorbidity (OB; n = 18), and a control group of eutrophic healthy individuals (BMI: 20 - 25 kg/m²) of same ages (E; n = 18). All groups (OBD, OB and E) performed the functional analyses [muscle strength (1RM) and cardiorespiratory fitness (VO2max)], anthropometry, body composition (Air Displacement Plethysmograph), blood collections for biochemical (anti-CMV) and molecular (gene expression of leptin, IL-2, IL-4, IL-6, IL-10, TNF-α, PD-1, P16ink4a, CCR7, CD28 and CD27) analyses of markers related to immunosenescence. Increased gene expression of leptin, IL-2, IL-4, IL-10, TNF-α, PD-1, P16ink4a, CCR7 and CD27 was found for the OBD and OB groups compared to the E group. Moreover, VO2max for the OBD and OB groups was significantly lower compared to E. In conclusion, obesity, regardless of associated disease, induces increased gene expression of markers associated with inflammation and immunosenescence in circulating leukocytes in obese middle-aged individuals compared to a eutrophic group of the same age. Additionally, increased adipose tissue and markers of chronic inflammation and immunosenescence were associated to impairments in the cardiorespiratory capacity of obese middle-aged individuals.

Objective: To evaluate the possibility of using fibroblast growth factor 21 (FGF 21) as a marker of metabolic disorders and premature aging in polymorbid cardiovascular pathology. Research methods: 199 men aged 35-55 years who were stratified into 3 groups were examined: group A - 117 patients with type 2 diabetes mellitus (type 2 diabetes), polymorbid cardiovascular disease (PCVD), obesity, androgen deficiency and anxiety-depressive disorders (ADD); group B - 55 patients with PCVD, obesity and ADD; group C - control group (n = 27). The examination of patients included a laboratory study of the level of FGF 21, indicators of carbohydrate and lipid metabolism, hormonal status, as well as daily monitoring of blood pressure and ECG. Results and conclusions. When compared with the control group, the level of FGF 21 was 3 times higher in the presence of type 2 diabetes. The most intense increase in FGF 21 levels was observed in groups of patients with several diseases. An increase in the level of FGF 21 in young and middle-aged people is probably due to a compensatory reaction to the existing androgen deficiency, disorders of carbohydrate and lipid metabolism. Strong correlations between FGF 21 and glucose, HDL cholesterol, total testosterone, ALT, and SBP during the day allow FGF 21 to be considered an early marker of cardiovascular disease and premature aging (PA) in young and middle-aged people

The paper analyzes the current literature data and the results of our own researches concerning the state of the cytokine network: pro- and anti-inflammatory cytokines (interleukin (IL) 1α, IL-1β, IL-4, IL-6, IL-10, IL-17 and tumor necrosis factor (TNF) α), α- and β-chemokines, including IL-8 and IL-16, as well as adipokines (leptin and adiponectin) in the peripheral blood of patients with type 2 diabetes (T2D) with normal and increased body weight/obesity. It has been shown that patients with T2D are cha­racterized by an increased content of proinflammatory cytokines (IL-1, IL-6, IL-17, TNFα), α- and β-chemokines in the peripheral blood, including IL-8 and IL-16, as well as leptin with a decrease in adiponectin content. In lean patients (with body mass index (BMI) < 25.5 kg/m2) compared to lean normoglycemic individuals from the control group (BMI < 25.5 kg/m2), there is a small but significant increase in IL-1β, IL-6, IL-17, TNFα and leptin, which, as BMI increases, significantly increases in severe obesity (BMI > 30.0 kg/m2), especially in obese women (BMI > 35.0 kg/m2). Similarly, an increase in proinflammatory cytokines is observed in normoglycemic people, but not as signifi­cant as in T2D. Less clear data were obtained when during determination of the anti-inflammatory cytokines IL-4 and IL-10, which is explained by a significant polymorphism of their genes, and both protective and compensatory effects on pro-inflammatory cytokine rise. In T2D patients, especially those with obesity, there is an increase in the leptin level and a decrease in the adiponectin content. The severity of the course and the percentage of mortality are closely associated with the BMI of patients. The effectiveness of the fight against an increase in the incidence of T2D should be primarily aimed at preventing obesity, and in case of already developed T2D — at reducing concomitant obesity. The analysis of the data presented also suggests that a sharp increase in the content of pro-inflammatory cytokines (so called cytokine storm) observed in patients with T2D and obesity infected with COVID-19, is a consequence of the summation and potentiation of already existing inflammatory process.

Midlife Type 2 Diabetes Mellitus (T2DM) is associated with a greater risk of dementia in later life. Peripheral inflammation and its impact on cognition is proposed as one of the pathological mechanisms mediating this link. However, studies have primarily focused on older individuals with established cognitive impairment and a long duration of T2DM. Importantly, knowledge of which individuals with midlife T2DM who are at greatest risk of later cognitive decline is lacking. We examined the cross-sectional relationship between serum levels of 8 pro-inflammatory markers (IL-1β, IL-6, TNF-α, IL-8, MCP-1, CXCL10, IL-12p70, CRP) and performance on a detailed neuropsychological assessment battery in middle-aged adults with uncomplicated T2DM (N = 89; 52 ± 8.1 years, 47% female) and matched healthy controls (N = 50; 52 ± 8.3 years, 59% female). Linear regression was used to analyze associations between serum markers and cognitive performance in the overall cohort, followed by a T2DM∗protein concentration interaction analysis to identify any T2DM-specific effects. We observed a significant T2DM-specific association between serum TNF-α levels and scores on the Paired Associates Learning (PAL) task (β: −3.16, SE: 1.32, p = 0.01, Std. Beta: −0.94), a task with significant working memory demands previously implicated in T2DM-related cognitive dysfunction. However, this did not persist on controlling for multiple testing. We provide exploratory evidence for a significant T2DM-specific relationship between serum TNF-α and memory performance. These findings require further replication and longitudinal analysis with the aim of selecting-out individuals with midlife T2DM at risk of future cognitive decline for potential preventative interventions.

Chemerin is a mediator of adipose tissue involved in the regulation of many processes, including lipogenesis, and inflammatory response. The role of chemerin in the development of insulin resistance has been insufficiently studied and needs detailed understanding. The aim of the study was to investigate chemerin production in obese patients with different states of carbohydrate metabolism. The study included 155 patients with a diagnosis of obesity; 34 patients with overweight. The control group 1 consisted of 43 conditionally healthy donors who did not have obesity. For comparison of the results of a study to determine the levels of tissue-specific mRNA expression of the genes IL-6, TNF-a, RARRES2, (encoding IL-6, TNF-a and chemerin) in adipose tissue introduced a control group 2 – 30 patients without obesity. Study on the relative level of mRNA expression of the genes IL-6, TNF-a and RARRES2 (encoding IL-6, TNF-a and chemerin) was carried out using real time PCR. Concentrations of IL-6, TNF-a, and chemerin were measured in serum/plasma using an enzyme-linked immunosorbent assay (ELISA). We found significant differences in the plasma level of chemerin and tissue-specific features of RARRES2 gene expression in obese patients, depending on the degree of obesity and the state of carbohydrate metabolism. Multidirectional associations of RARRES2 gene expression with TNF-a and IL-6 genes in adipose tissues of different localization are shown: in obese patients (BMI £40 kg/m2) without type 2 diabetes – negative, and type 2 diabetes – positive. Identified relationship chemerin plasma content and the expression level of its gene in biopsies with various parameters of carbohydrate and lipid metabolism, proinflammatory molecules indicate chemerin involved in metabolic and immune processes in obesity.

Currently, qigong and tai chi exercises are the two most common preventive as well as therapeutic interventions for chronic metabolic diseases such as type 2 diabetes mellitus (T2DM). However, the quantitative evaluation of these interventions is limited. This study aimed to evaluate the therapeutic efficacy of qigong and tai chi intervention in middle-aged and older adults with T2DM. The study included 103 eligible participants, who were randomized to participate for 12 weeks, in one of the following intervention groups for the treatment of T2DM: fitness qigong, tai chi, and control group. Three biochemical measures, including fasting plasma glucose (FPG), glycated hemoglobin (HbA1C), and C-peptide (C-P) levels, assessed at baseline and 12 weeks, served as the primary outcome measures. During the training process, 16 of the 103 participants dropped out. After the 12-week intervention, there were significant influences on HbA1C (F2,83 = 4.88, p = 0.010) and C-P levels (F2,83 = 3.64, p = 0.031). Moreover, significant reduction in C-P levels was observed after 12-week tai chi practice (p = 0.004). Furthermore, there was a significant negative correlation between the duration of T2DM and the relative changes in FPG levels after qigong intervention, and the relative changes in HbA1C levels were positively correlated with waist-to-height ratio after tai chi practice. Our study suggests that targeted qigong exercise might have a better interventional effect on patients with a longer duration of T2DM, while tai chi might be risky for people with central obesity. Trial registration: This trial was registered in Chinese Clinical Trial Registry. The registration number is ChiCTR180020069. The public title is “Health-care qigong · study for the prescription of chronic diabetes intervention.”

Introduction: The benefits of Diabetic Camp as known can be applied to promote knowledge and self management among diabetes people. Nevertheless, empirical data of its effect on diabetes self-efficacy are still limited, especially on middle aged and elderly people with type 2 Diabetes Mellitus. Objectives: The purpose of this intervention study was to investigate the change of self-efficacy among middle-aged and elderly people living with type 2 DM after attending camp. Methods: A quasi-experimental study was used. Eighty-four participants were recruited form two public health center in Bukittnggi City West Sumatra Indonesia were randomly assigned into either the experimental group (n=42) or control group (n=42) by matching technique based on gender , age, and duration of illness. The experimental group participated in diabetic camp for two days continuing with weekly follow up for over 1 month while those in the control group participated in routine activities. Outcome was measured by using Self-efficacy Questionnaire for Diabetes at the first day before receiving the intervention as pretest data, and on the four weeks after the intervention was completed as the posttest data. The reliability of the Self-efficacy Questionnaire for Diabetes with Cronbach's alpha coefficient was 0.81. Descriptive and inferential statistics were performed to analyze the data. Results: Mean of self-efficacy score in the experimental group after receiving the intervention was significantly higher than those in the control group (t =4.27; p&lt;0.05). The mean of self-efficacy score after receiving the intervention in the experimental group was increased significantly from before receiving the intervention (t = 8.15; p&lt;0.05). Conclusions: The results showed that Diabetic camp was effective in promoting self-efficacy of middle-aged and elderly people with type 2 DM. Thus, this diabetes care program can be recommended for practice

Prevention of hepatic fat accumulation may be an important approach for liver diseases due to the increased relevance of hepatic steatosis in this field. This study was conducted to investigate the effects of the antioxidant α-lipoic acid (α-LA) on hepatic steatosis, hepatocellular function, and oxidative stress in a model of type 2 diabetes fed with a high fat diet (HFD). Goto-Kakizaki rats were randomly divided into four groups. The first group received only a standard rat diet (control GK) including groups 2 (HFD), 3 (vehicle group), and 4 (α-LA group), which were given HFD, ad libitum during three months. Wistar rats are the non-diabetic control group. Carbohydrate and lipid metabolism, liver function, plasma and liver tissue malondialdehyde (MDA), liver GSH, tumor necrosis factor-α (TNF-α) and nuclear factor E2 (erythroid-derived 2)-related factor-2 (Nrf2) levels were assessed in the different groups. Liver function was assessed using quantitative hepatobiliary scintigraphy, serum aspartate, and alanine aminotransferases (AST, ALT), alkaline phosphatase, gamma-glutamyltranspeptidase, and bilirubin levels. Histopathologically steatosis and fibrosis were evaluated. Type 2 diabetic animals fed with HFD showed a marked hepatic steatosis and a diminished hepatic extraction fraction and both were fully prevented with α-LA. Plasma and liver tissue MDA and hepatic TNF-α levels were significantly higher in the HFD group when compared with the control group and significantly lower in the α-LA group. Systemic and hepatic cholesterol, triglycerides, and serum uric acid levels were higher in hyperlipidemic GK rats and fully prevented with α-LA. In addition, nuclear Nrf2 activity was significantly diminished in GK rats and significantly augmented after α-LA treatment. In conclusion, α-LA strikingly ameliorates steatosis in this animal model of diabetes fed with HFD by decrementing the inflammatory marker TNF-α and reducing oxidative stress. α-LA might be considered a useful therapeutic tool to prevent hepatic steatosis by incrementing antioxidant defense systems through Nrf2 and consequently decreasing oxidative stress and inflammation in type 2 diabetes.

This study is to observe the distribution of intestinal flora and the changes of inflammatory factors in elderly patients with myocardial ischemia complicated with type 2 diabetes mellitus. A total of 106 elderly patients with myocardial ischemia complicated with type 2 diabetes mellitus (complicated group), 106 elderly patients with simple type 2 diabetes mellitus (diabetic group), and 106 healthy elderly people (control group) were selected. The fasting blood glucose (FBG), 1-h postprandial blood glucose (1hPG), 2-h postprandial blood glucose (2hPG), 3-h postprandial blood glucose (3hPG), and hemoglobin A1c (HbA1c) in complicated group and the diabetic group were higher than those in the control group ( P < 0.05 or P < 0.01). The duration of diabetes, FBG, 3hPG, and HbA1c in the complicated group were higher than those in the diabetic group, while the 2hPG was lower than that in the diabetic group ( P < 0.05). Compared with control group, the number of Enterobacteria in the diabetic group and complicated group was increased, while the numbers of Bacteroides, Bifidobacteria, and Lactobacillus were decreased ( P < 0.05 or P < 0.01). Compared with the diabetic group, the number of Enterobacteria in complicated group was increased, while the numbers of Bacteroides, Bifidobacteria, and Lactobacillus were decreased ( P < 0.05 or P < 0.01). Compared with control group, the levels of tumor necrosis factor alpha (TNF-α), interleukin 6 (IL-6), interleukin 1 beta (IL-1β), and C-reactive protein (CRP) decreased in the diabetic group and complicated group, and the lowest in the complicated group. Conversely, the levels of interleukin 10 (IL-10) and interleukin 12 (IL-2) increased in the diabetic group and complicated group, and the highest in the complicated group ( P < 0.05 or P < 0.01). Multiple logistic regression analysis showed that the duration of diabetes, HbA1c, Enterobacteria, TNF-α, IL-6, and IL-10 were the influencing factors of myocardial ischemia complicated with type 2 diabetes mellitus ( P < 0.05 or P < 0.01). In conclusion, in the elderly patients with myocardial ischemia complicated with type 2 diabetes mellitus, the number of intestinal probiotics and the level of anti-inflammatory factors decreased, and the number of pathogenic bacteria and the level of inflammatory factors increased. Enterobacteria, TNF-α, IL-6, and IL-10 may play an important role in the development of myocardial ischemia in type 2 diabetes mellitus.

The objective of the present study was to identify the association of the TNF-α- 308G/A and leptin receptor (LEPR) Gln223Arg polymorphisms with the risk of development of type 2 diabetes mellitus (T2DM). Methods: A total of 160 volunteers were studied: 108 with T2DM and 52 participants as control, who served as the control group. Polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) for the genomic region of TNF-α- 308G/A and LEPR Gln223Arg were carried out. Results: The frequency of LEPR Gln223Arg genotypes in T2DM and control groups showed significant differences in the distribution of genotypes (p < 0.05). The frequency also of TNF-α- 308G/A genotypes in T2DM and control subjects showed significant differences in the distribution of genotypes (p < 0.05). Conclusion: Our results indicate that there are significant differences in the distribution of genotypes and alleles between the individuals with T2DM and control subjects (p < 0.05).
