The association between plasma fatty acid and cognitive function mediated by inflammation in patients with type 2 diabetes mellitus

Abstract In this study, we evaluated the cognitive function of 372 Chinese patients (214 males and 158 females; the average age was 57.09 ± 9.00 years) with type 2 diabetes mellitus (T2DM) by using the mini-mental state examination (MMSE) and the Montreal cognitive assessment (MoCA), with Plasma fatty acids measured by gas chromatography analysis and inflammatory cytokines determined by immune turbidimetric analysis and enzyme-linked immunosorbent assay (ELISA) to investigate whether there was a correlation between the plasma fatty acids, plasma inflammatory cytokine levels and cognitive test scores in Chinese patients with T2DM. We found the increasing of body mass index (BMI) might lead to cognitive impairment and induce inflammatory response. Higher saturated fatty acids (SFAs) levels in plasma were linked to cognitive decline, while higher monounsaturated fatty acids (MUFAs) intake might be a protective factor for cognitive function. In addition, most polyunsaturated fatty acids (PUFAs) levels stood out as having increasing trends that were positively correlated to cognitive function scores. In our study, we found higher SFAs led to higher proinflammatory factor levels. Apart from that, MUFAs and stearoyl-CoA desaturase-18 (SCD-18) were positively related to hypersensitive C-reactive protein (hs-CRP) (P<0.05; P<0.05; P<0.05). Meanwhile, our result also indicated that the increasing of C18:0 might reduce MoCA language skill scores by regulating plasma IL-10 levels. Plasma fatty acids could improve or damage cognitive function by regulating IL-10, which suggested plasma fatty acids could be evaluated as a potential indicator of cognitive function decline in T2DM.

Abstract Background High fat diet may lead to systematic inflammation in patients with type 2 diabetes, which eventually result in neuronal damage and cognitive decline. However, there is a paucity of study examined whether inflammation mediated the association between diet fatty acids and cognitive function in type 2 patients with diabetes. Methods We evaluated the cognitive function of 372 Chinese patients with diabetes, using the mini-mental state examination (MMSE) and the montreal cognitive assessment (MoCA). Plasma fatty acids were measured by gas chromatography analysis. Inflammatory cytokines were determined by immune turbidimetric analysis and enzyme-linked immunosorbent assay (ELISA). Data was analyzed using multiple linear regression based on R program and mediation model was established by Mplus. Results In our study, we found the increasing of BMI may lead to cognitive impairment and induce inflammatory response. We also found higher SFAs levels in plasma were linked to cognitive decline, while higher MUFAs intake might be a protective factor for cognitive function. In addition, most PUFAs levels stood out as having increasing trends that were positively correlated to cognitive function scores, but n-6 PUFAs gave opposite results. In our study, we found higher SFAs led to higher proinflammatory factor levels. Apart from that, MUFAs, SCD-16 and SCD-18 were positively related to hs-CRP. Interestingly, we found PUFAs were negatively related to IL-10. Meanwhile, this result also indicated that C18:0 might reduce MoCA language skills scores by regulating plasma IL-10 levels. Conclusions Plasma fatty acids could improve or damage cognitive function by regulating IL-10, which suggested that plasma fatty acids can be evaluated as a potential indicator of cognitive function decline in 2 type diabetes.

Abstract Objective Myonectin is one of the myokines and has gained interest as a potential new strategy to combat obesity and its associated disorders, such as type 2 diabetes mellitus (T2DM).The objective of this study was to investigate circulating serum myonectin levels in nondiabetes and T2DM and elucidate possible relationships between serum myonectin levels and metabolic parameters in patients with T2DM. Design A total of 362 Chinese patients with T2DM and 100 age- and sex-matched healthy controls were recruited in this study. Clinical characteristics, blood biochemistry, and circulating myonectin levels were measured by enzyme-linked immunosorbent assay. Results Circulating myonectin levels were significantly decreased in T2DM compared with controls. Obese nondiabetic controls had significantly lower serum myonectin levels compared with lean nondiabetic controls. In diabetic patients, serum myonectin concentrations were significantly negatively correlated with body mass index (BMI), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), C-reactive protein (CRP), hemoglobin A1c (HbA1c), fasting insulin (Fins), the homeostatic model assessment of insulin resistance (HOMA-IR), visceral fat area, and subcutaneous fat area. After adjusting for covariates, multivariate stepwise regression analysis demonstrated that BMI, LDL-C, TG, HOMA-IR, and visceral fat were the main independent predictors of low serum myonectin concentrations. Conclusions Circulating myonectin levels were decreased in T2DM patients and in obese subjects. Moreover, serum myonectin levels were correlated with metabolic markers of T2DM. These data suggest that myonectin may be a useful marker in predicting the development of obesity and T2DM.

Abstract Background The adipokine adipsin contributes to insulin resistance (IR), inflammation, and obesity, which are all regarded as high-risk factors for mild cognitive impairment (MCI) in patients with type 2 diabetes mellitus. This research aimed to uncover the role of adipsin in Chinese type 2 diabetes mellitus (T2DM) population with early cognitive dysfunction and determine whether adipsin contributes to diabetic MCI caused by IR. Methods In our study, 126 patients with T2DM were enrolled. The Montreal Cognitive Assessment (MoCA) was used to assess cognitive impairment. Demographic data and neuropsychological test results were evaluated. Plasma adipsin level was measured by enzyme-linked immunosorbent assay. Results The MCI group (n = 57) presented higher plasma adipsin levels compared with the healthy controls (p = 0.018). After adjustment for educational attainment, and age, begative correlations were found between plasma adipsin levels and MoCA, Mini Mental State Exam, and Verbal Fluency Test scores(r = − 0.640, p < 0.001; r = − 0.612, p < 0.001; r = − 0.288, p = 0.035; respectively). Correlation analysis demonstrated that adipsin levels were significantly positively correlated with fasting C-peptide; homeostasis model of assessment for insulin resistance (HOMA-IR) (r = 0.368, p < 0.001; r = 0.494, p < 0.001; respectively). Multivariable regression analysis further indicated that high plasma adipsin level was a significant independent determinant of MCI in the Chinese population withT2DM (p = 0.017). Conclusions Elevated plasma adipsin level was associated with MCI in Chinese T2DM patients. Further large-scale studies should be designed to determine whether adipsin is linked to IR-associated susceptibility to early cognitive decline in T2DM patients.

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): This study was funded by (subject of fundamental scientific research on a state assignment № АААА-А17-117052310073-6 от 23.05.2017 Introduction. Growth differentiation factor-15 (GDF-15) is a biomarker associated with inflammatory processes in the pathogenesis of chronic heart failure (CHF) which expresses in cardiomyocytes under pathological conditions. The relationship between the level of GDF-15 and type 2 diabetes mellitus (T2DM) has also been proven. It is necessary to study GDF-15 in patients with CHF and T2DM. Aim To investigate the association between serum GDF-15 levels in patients with CHF of ischemic etiology and the concentration of the main leukocyte fractions depending on presence or absence of T2DM. Material and methods. The study included 42 patients. The patients were divided into 2 groups. The first group consisted of patients with CHF and T2DM (n = 14). The second group consisted of patients with CHF without T2DM (n = 28). Determination of GDF-15 concentration was carried out by enzyme-linked immunosorbent assay (BioVendor, Czech Republic). The absolute concentration of lymphocytes, neutrophils, as well as the ratio of neutrophils to lymphocytes in the blood were analyzed. Statistical analysis was performed using the Statistica software (v.10.0). The data were described as a median and interquartile range, the Mann-Whitney test was used to compare them. The correlation analysis was tested using the Spearman"s correlation coefficient. Results and discussion. The average level of the GDF-15 in the study groups was comparable: 2389 (2104; 3375) pg/ml and 2309 (2047; 3014) pg/ml in the first and second groups, respectively (p = 0.6). In the general cohort of CHF patients, the GDF-15 concentration was not correlate with the lymphocytes concentration (r = -0.001, p = 0.95), neutrophils (r = -0.14, p = 0.4) and the ratio of neutrophils to lymphocytes (r = -0.12, p = 0.25). At the same time, in the group of patients with T2DM, a significant negative correlation was revealed between the concentration of GDF-15 in the serum and the concentration of neutrophils (r = -0.6, p = 0.022). While both other analyzed parameters did not demonstrate significant correlations with GDF-15 (p > 0.05). In the group of CHF patients without T2DM, no correlations were found between GDF-15 and the studied parameters, including neutrophils (r = 0.02, p = 0.3). Along with this the median of the neutrophils concentration did not vary among groups (3.5 (2.3; 5.3) vs 3.2 (2.7; 4.1) * 109 / l; p = 0.8). Conclusion The concentration of the inflammatory marker GDF-15 in the blood of patients with CHF in combination with T2DM correlates with the concentration of neutrophils. In the absence of T2DM, no significant correlations were found between GDF-15 and the main leukocyte fractions. The results obtained indicate the possible prospect of using the GDF-15 biomarker in a cohort of patients with CHF in combination with T2DM.

Abstract Background Serum wnt1-induced signaling pathway protein 1 (WISP1) levels are increased with obesity, which is a common complication associated with lower extremity atherosclerotic disease (LEAD). However, to date, the relationship between elevated WISP1 levels and the incidence of lower extremity atherosclerotic disease (LEAD) in type 2 diabetes mellitus (T2DM) remains unclear. Methods 174 newly diagnosed type 2 diabetic patients were enrolled in our study. Patients were divided into two groups, LEAD group (n=100) and control group (n=74). Anthropometric parameters, blood pressure and some biochemical parameters were obtained. Body composition was detected by bioelectrical impedance analysis (BIA). Levels of serum insulin were determined by radioimmunoassay. Serum WISP1 and interleukin 6 (IL-6) levels were determined using an enzyme-linked immunosorbent assay. Results It was shown that serum WISP1 levels in diabetic patients with LEAD were higher than those without LEAD (P<0.001). Serum WISP1 levels were positively related with waist circumference (r=0.237, P=0.003), waist-hip ratio (r=0.22, P=0.006), visceral fat area (r=0.354, P<0.001), serum creatinine (r=0.192, P=0.012), interleukin 6 (r=0.182, P=0.032), c-reactive protein (r=0.681, P<0.001), triglycerides (r=0.119, P<0.001), fasting glucose (r=0.196, P=0.011), glycated hemoglobin (r=0.284, P<0.001), and HOMA-IR (r=0.285, P<0.026). Compared with the lowest tertile, the odds ratio of the middle tertile for LEAD incidence was 3.27 (95% CI, 1.24–8.64) and 4.46 (95% CI, 1.62–12.29) for the highest tertile after adjusting confounding factors. Conclusion The results suggest that increased serum WISP1 levels independently contribute to the incidence of LEAD in patients with newly diagnosed T2DM.
