AbstractMacrophages and adipocytes contribute to release of cytokines resulting in the chronic inflammatory profile of the metabolic syndrome. The local increase of proinflammatory cytokines impairs adipogenesis, resulting in formation of dysfunctional adipocytes that are unable to store and handle lipids. The altered lipid fluxes in/from adipocytes affect whole-body metabolism. We investigated the role of androgens on adipocyte-derived proinflammatory and anti-inflammatory cytokines during preadipocyte differentiation.Various differentiation methods were used to obtain full conversion of 3T3-L1 into mature adipocytes. The degree of adipocyte conversion in the presence/absence of dihydrotestosterone (DHT) was analyzed by measuring intracellular triglycerides (Oil Red O staining). The effects of DHT administration on interleukin 1β (IL-1β), IL-2, IL-6, IL-10, IL-12, interferon γ (IFNγ) and tumor necrosis factor α (TNFα) secretion was measured at days 0, 4, 6 and 8 of differentiation using the SearchLight multiplex protein array.DHT regulates a number of cytokines in committed and mature 3T3-L1 adipocytes. IL-1β and TNFα were readily suppressed at the very early stages of differentiation. IFNγ release was inhibited at day 4, but the effect was no longer detectable on day 8. IL-6 and IL-12 were significantly reduced at day 8 of differentiation. Conversely, the differentiation-dependent increase of IL-2 and IL-10 was further stimulated by DHT since day 0.We provide evidence that androgens promote an anti-inflammatory profile that parallels the acquisition of a functional adipocyte phenotype. The crosstalk between androgens, adipocyte-derived mediators of inflammation and intracellular lipid fluxes could have profound implications on metabolism of men with obesity and metabolic syndrome.

Abstract Introduction. The metabolic syndrome (MS) has been related to the unbalance between pro- and anti-inflammatory cytokines; where adiponectin, an anti-inflammatory adipokine, is considered to play a key metabolic role. The consumption of certain micronutrients has been claimed to modify pro- and anti-inflammatory cytokines. Aim. To explore whether dietary micronutrients are related with plasma adiponectin in patients with MS. Methods. Cross-sectional analysis. Quartiles of dietary bioactive compounds were compared according to values of plasma adiponectin. Interquartile variation (IQV) and correlation analyses were performed. Results. There was a significant IQV of dietary unsaturated fatty acids (between -50% to -66% of change, p25 vs p75, p<0.05), particularly for trans-fatty acids, poly-unsaturated fatty acids, mono-unsaturated fatty acids and w-6 fatty acids, in relation to plasma adiponectin; as well as a negative correlation (rho= -0.53, -0.37, -0.29 and -0.34, respectively; p<0.05). Conclusion. Dietary amounts of unsaturated fatty acids inversely related to plasma adiponectin in patients with MS.

AbstractWe investigated early effects of Whole-Body Electromyostimulation added to hypocaloric diet on metabolic syndrome features in sedentary middle-aged individuals. We randomly assigned 25 patients to Whole-Body Electromyostimulation plus caloric restriction or caloric restriction alone for 26 weeks. Anthropometrics, blood pressure, fasting glucose and insulin, HOMA-IR, glycated hemoglobin, lipids, uric acid, creatinphosphokynase, C-reactive protein were assessed. Body composition was evaluated with direct-segmental, multi-frequency Bioelectrical Impedance Analysis. Both groups lost approximately 10% of weight, with similar effects on waist circumference and fat mass. Change in free-fat mass was significantly different between groups (caloric restriction −1.5±0.2 vs. Whole-Body Electromyostimulation plus caloric restriction +1.1±0.4 kg, p=0.03). Whole-Body Electromyostimulation plus caloric restriction group experienced greater percent reductions in insulin (−45.5±4.4 vs. −28.2±3.6%, p=0.002), HOMA-IR (–51.3±3.2 vs. –25.1±1.8%, p=0.001), triglycerides (−22.5±2.9 vs. −4.1±1.6%, p=0.004) and triglycerides/HDL (p=0.028). Subjects trained with Whole-Body Electromyostimulation had also significant improvement in systolic pressure (138±4 vs. 126±7 mmHg, p=0.038). No discontinuations for adverse events occurred. In middle-aged sedentary subjects with the metabolic syndrome, Whole-Body Electromyostimulation with caloric restriction for 26 weeks can improve insulin-resistance and lipid profile compared to diet alone. Further studies are needed to ascertain long-term efficacy and feasibility of this approach in individuals with the metabolic syndrome.

AbstractBackgroundThe metabolic syndrome (MetS) is an obesity-driven disorder with pandemic proportions and limited treatment options. Oxidative stress, low-grade inflammation and altered autonomic regulation, are important components of MetS pathophysiology. We recently reported that galantamine, an acetylcholinesterase inhibitor and an FDA-approved drug (for Alzheimer’s disease) alleviates the inflammatory state in MetS subjects. Here we examined the effects of galantamine on oxidative stress in parallel with inflammatory and cardio-metabolic parameters in subjects with MetS.MethodsThe effects of galantamine treatment, 8 mg daily for 4 weeks, followed by 16 mg daily for 8 weeks or placebo were studied in randomly assigned subjects with MetS (n=22 per group) of both genders. Oxidative stress, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase activities, lipid and protein peroxidation, and nitrite levels were analyzed before and at the end of the treatment. In addition, plasma cytokine and adipokine levels, insulin resistance (HOMA-IR) and other relevant cardio-metabolic indices were analyzed. Autonomic regulation was also examined by heart rate variability (HRV) before treatment, and at every 4 weeks of treatment.ResultsGalantamine treatment significantly increased antioxidant enzyme activities, including SOD (+1.65 USOD/mg protein, [95% CI 0.39 to 2.92], P=0.004) and CAT (+0.93 nmol/mg, [95% CI 0.34 to 1.51], P=0.011), decreased lipid peroxidation (thiobarbituric acid reactive substances, -5.45 pmol/mg, [95% CI -10.97 to 0.067], P=0.053) and systemic nitrite levels (-0.05 nit/mg protein, [95% CI -0.21 to 0.10], P=0.038) compared with placebo. In addition, galantamine significantly alleviated the inflammatory state and insulin resistance, and decreased the low frequency/high frequency ratio of HRV, following 8 and 12 weeks of drug treatment.ConclusionLow-dose galantamine alleviates oxidative stress, alongside beneficial anti-inflammatory, and metabolic effects, and modulates autonomic regulation in subjects with MetS. These findings are of considerable interest for further studies with galantamine to ameliorate MetS pathophysiology.

BACKGROUND: Along with the increase in obesity is a parallel increase in the prevalence of metabolic complications of obesity, often referred to as the metabolic syndrome (MetS). The role of adipose tissue in MetS has continued to evolve with the description of numerous secretory peptides from adipocytes named adipocytokines or adipokines. Recent studies have found visfatin as the regulation of inflammatory and immunomodulating prosesses, meanwhile adiponectin was known to have a potent anti-inflammatory properties. Here we try to assess the correlation between those two adipokines to MetS, via an inflammatory pathway.METHODS: This was a cross-sectional study on 128 non diabetic obese male subject (waist circumferences ≥90 cm). Visfatin and adiponectin were assessed by ELISA. Statistical analysis was performed using SPSS for Windows v.16.00 with signifcantly p<0.05. The correlations among biomarkers were assessed using Spearman's Rho test.RESULTS: This study showed a significant positive correlation between levels of visfatin and inflammatory markers TNF-α (r=0.22, p<0.005), and hsCRP (r=0.12, p=0.19), significant negative correlation between levels of adiponectin and TNF-α (r=-0.22-8, p<0.005-1), adiponectin and hsCRP (r=-0.14, p=0.11) and visfatin (r=-0.029, p<0.01). Plasma visfatin levels were increased along with the number MetS components, white plasma adiponectin showed inversely relation.CONCLUSION: Our present study has shown that visfatin has a proinflammatory properties and adiponectin has an anti-inflammatory properties, and how they have an opposite effects on MetS. Visfatin was found to have a positive correlaton while adiponectin was found to have a negative correlation with the number of MetS components.KEYWORDS: Obesity, Inflammation, Metabolic Syndrome, Adipocytokines, Visfatin, Adiponectin, TNF-α, hsCRP

Purpose: To determine the levels of pro-inflammatory cytokines and soluble mediators (TNF-α, IL6, IL2, and PDGF-AB) in 28 vitreous biopsies taken from patients with proliferative diabetic retinopathy (PDR) and treated with increasing doses of curcumin (0. 5 and 1 μM), with or without homotaurine (100 μM) and vitamin D3 (50 nM).Materials and Methods: ELISA tests were performed on the supernatants from 28 vitreous biopsies that were incubated with bioactive molecules at 37°C for 20 h. The concentration of the soluble mediators was calculated from a calibration curve and expressed in pg/mL. Shapiro-Wilk test was used to verify the normality of distribution of the residuals. Continuous variables among groups were compared using the General Linear Model (GLM). Homoscedasticity was verified using Levene and Brown-Forsythe tests. Post-hoc analysis was also performed with the Tukey test. A p ≤ 0.05 was considered statistically significant.Results: The post-hoc analysis revealed statistically detectable changes in the concentrations of TNF-α, IL2, and PDGF-AB in response to the treatment with curcumin, homotaurine, and vitamin D3. Specifically, the p-values for between group comparisons are as follows: TNF-α: (untreated vs. curcumin 0.5 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.008, (curcumin 0.5 μM vs. curcumin 0.5 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.0004, (curcumin 0.5 μM vs. curcumin 1 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.02, (curcumin 1 μM vs. curcumin 0.5 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.025, and (homotaurine 100 μM + vitamin D3 50 nM vs. curcumin 0.5 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.009; IL2: (untreated vs. curcumin 0.5 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.0023, and (curcumin 0.5 μM vs. curcumin 0.5 μM+ homotaurine 100 μM + vitamin D3 50 nM) p = 0.0028; PDGF-AB: (untreated vs. curcumin 0.5 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.04, (untreated vs. curcumin 1 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.0006, (curcumin 0.5 μM vs. curcumin 1 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.006, and (homotaurine 100 μM + vitamin D3 50 nM vs. curcumin 1 μM + homotaurine 100 μM + vitamin D3 50 nM) p = 0.022. IL6 levels were not significantly affected by any treatment.Conclusions: Pro-inflammatory cytokines are associated with inflammation and angiogenesis, although there is a discrete variability in the doses of the mediators investigated among the different vitreous samples. Curcumin, homotaurine, and vitamin D3 individually have a slightly appreciable anti-inflammatory effect. However, when used in combination, these substances are able to modify the average levels of the soluble mediators of inflammation and retinal damage. Multi-target treatment may provide a therapeutic strategy for diabetic retinopathy in the future.Clinical Trial Registration : The trial was registered at clinical trials.gov as NCT04378972 on 06 May 2020 (“retrospectively registered”) https://register.clinicaltrials.gov/prs/app/action/SelectProtocol?sid = S0009UI8&amp;selectaction = Edit&amp;uid = U0003RKC&amp;ts = 2&amp;cx = dstm4o.

Aim. To study the levels of pro- and anti-inflammatory cytokines in cervical secretion in females with cervical epithelial dysplasia and latent papillomavirus infection. Methods. The study included 120 females aged 20 to 40 years with cervical papillomavirus infection, who were assigned to two groups using «case-control» method. The first group included 60 females with latent disease, the second group - 60 females with mild and moderate cervical epithelial dysplasia (cervical intraepithelial neoplasia stages I and II). Cytokine levels in cervical secretion were measured by ELISA using «ProCon» test system. Results. ELISA test showed increased levels of interleukin-4 and interleukin-10 (43 [21; 74] and 48 [12; 88] pg/ml, respectively) and decreased levels of interleukin-2 (18.5 [5.5; 27.5] pg/ml), interleukin-6 (0.6 [0.06; 0.9] pg/ml), tumor necrosis factor alpha (88.5 [0; 123] pg/ml), interferon γ (2 [0; 4] pg/ml) in cervical secretion of females with cervical epithelial dysplasia compared to females with latent papillomavirus infection. Thus, females with cervical epithelial dysplasia showed increased levels of anti-inflammatory cytokines: interleukin-4 - by 2.7 times and interleukin-10 - by 2.4 times compared to females with latent disease, while levels of pro-inflammatory cytokines was decreased as following: interleukin-2 - by 1.4 times, interleukin-6 - by 4.5 times, tumor necrosis factor alpha - by 1.8 times, interferon γ - by 6.3 times (p 0.05). Conclusion. Imbalance of immune response cytokine regulation with anti-inflammatory cytokines prevailing might be an important factor facilitating persistence of papillomavirus in cervical epithelium and contributing to cervical epithelial dysplasia onset and progression.

Objective: The aim of this study was to verify the influence of 6 weeks of whole-body vibration training on the pro- and anti-inflammatory cytokines (IL-2, IL-4, IL-6, IL-10, IFN-ɣ e TNF-α) in young, eutrophic and sedentary women. Methods: Twenty-six participants were randomly divided into two groups: Vibratory Platform Group (GV, n = 13) and Ergometry Group (GE, n = 13). The training program of both groups was of 20 minutes / session, 3 times per week, in non-consecutive days for 6 weeks. The load of the training was adjusted with the adapted Borg scale. GE was submitted to aerobic activity sessions in a cycle ergometer. GV was submitted to vibration platform stimulation sessions. After training program both groups were submitted to 6 weeks of detraining. Results: GV increased levels of IL-4, IL-6, IL-10 and TNF-α after training, and it decreased all of them after detraining phase. GE increased IL2, IL-4, IL-6 and IL-10 only after the detraining period. Conclusion: 6 weeks of whole-body vibration training can promote an increase in pro- and anti-inflammatory cytokines in young, eutrophic and sedentary women, however these effects seem to be transitory as the exercise is discontinued.

Global Threat

Metabolic syndrome is an emerging global threat as a major health burden. It is widely presumed that Metabolic syndrome is associated with a low grade chronic inflammatory phenomenon. This inflammatory state is due to the imbalance between the pro and anti-inflammatory cytokines. Studies have been performed on various inflammatory markers in metabolic syndrome like hsCRP, TNF-alpha, Adiponectin, IL-6, IL-10. Articles were chosen from indexed journals from various search engines. Pro inflammatory cytokines like hsCRP, TNF – alpha, Interleukin -6 were found to be increased and anti-inflammatory cytokines like Interleukin – 10 were reduced in metabolic syndrome.
