Background: Fibroblast Growth Factor 21 (FGF21) serum levels are associated with insulin resistance and metabolic syndrome in HIV patients. Objective: To quantify FGF21 levels in HIV patients using antiretroviral therapy (ART) and to analyze a possible association between serum FGF21 levels and lipid profile, levels of proinflammatory cytokines, and atherogenic risk factors. Materials and Methods: Twenty patients with HIV infection, who received ART in a scheme consisting of Tenofovir/Emtricitabine+Lopinavir/Ritonavir, were enrolled in this study. The serum levels of FGF21, inflammatory parameters (IL-6 and IL-1β), glucose, cholesterol, triglycerides, and insulin were determined at baseline and after 36 weeks of treatment. The homeostatic model assessment for insulin resistance (HOMA-IR) and the atherogenic risk factor were also calculated. Results: After 36 weeks, serum FGF21 levels decreased significantly (p=0.011), whereas IL-6 levels (r=0.821, p=0.0001) and the CD4+ T cell count (r=0.446, p=0.048), showed a positive correlation with the decrease in FGF21 levels. There was an increase in total cholesterol (r=-0.483, p=0.031), LDL (r=-0.496, p=0.026), VLDL (r=-0.320, p=0.045), and the atherogenic index factor (r=-0.539, p=0.014), these values showed a negative correlation with FGF21 levels. Conclusions: The decrease of serum FGF21 levels due to ART is associated with the alteration in lipid profile and an increased risk for cardiovascular diseases. These variations are predictors of inflammatory status in HIV patients using antiretroviral therapy.

Objective:to determine the incidence of insulin resistance (IR) in patients with rheumatoid arthritis (RA) and to assess the relationship of IR to blood lipid profile changes and the presence of metabolic syndrome (MS).Subjects and methods.The investigation enrolled 47 RA patients (41 women and 6 men) without a history of diabetes mellitus (DM) and with normal fasting glucose levels during examination. The patients' median age was 56 [39; 62] years; disease duration – 6 [5; 14] years. Most of the patients had low (40.4%) or moderate (42.6%) RA activity (DAS28). IR was diagnosed using the Homeostastic Model Assessment of Insulin Resistance (HOMA-IR) index 2.77. The presence of MS was assessed by the National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATPIII) criteria and the International Diabetes Federation (IDF) criteria.Results and discussion.The median HOMA-IR value in RA patients was 1.7 [1.1; 3.2]. The HOMA-IR index correlated with age (r=0.3; p=0.04), body mass index (r=0.6; p<0.001), waist circumference (r=0.6; p<0.001), and the concentrations of total cholesterol (r=0.3; p=0.02) and triglycerides (TG) (r=0.5; p<0.001). All the patients were divided into two groups: 1) 15 patients with IR; 2) 32 patients without IR. The patients of both groups were matched for sex, age, RA duration and activity, and therapy, but the RA patients with IR more often had abdominal obesity (100.0 and 37.5%), hypertriglyceridemia (33.3 and 6.3%) and the atherogenic index >3.0 (40.0 and 6.3%, respectively; p<0.05 in all cases). MS was diagnosed using the NCEP/ATPIII criteria in 46.7% of cases with RI and in 6.3% of those without IR; MS was identified by the IDF criteria in 60.0 and 12.5% of cases, respectively (p<0.01 in all cases). There were no differences between groups in the incidence of hypertension, myocardial infarction, or in the frequency of surgeries for myocardial revascularization.Conclusion.More than 30% of RA patients without DM have IR (HOMA-IR ≥2.77). IR in RA is associated with obesity, elevated blood TG levels, and a proatherogenic lipid profile. The use of the criteria for MS could not always allows suspect IR in patients with RA.

Insulin resistance is a well-documented risk factor for the development of endometrial cancer. Adiponectin and vaspin are insulin-sensitizing proteins that are secreted from adipose tissue. A clear association between serum levels of adipokines and endometrial cancer has yet to be established. The study group consisted of postmenopausal women with confirmed endometrial cancer, whereas patients with benign endometrial conditions constituted the control group. The two groups were compared in terms of insulin resistance and serum levels of adiponectin and vaspin. A total of 60 patients with confirmed endometrial cancer and 70 controls with benign endometrial conditions (polyps and atrophy) were enrolled. Median homeostasis model assessment of insulin resistance value was significantly higher in the study group compared with the control group (2.93 vs 1.27, P<0.0001), whereas mean quantitative insulin sensitivity check index value was significantly lower (0.33±0.02 vs 0.37±0.37, P<0.0001). Median values for both adiponectin and vaspin were significantly lower in patients with endometrial cancer compared with the control group (4.09 vs 17.13 μg/ml, P<0.0001 and 0.21 vs 0.39 ng/ml, P<0.0001 respectively). Low levels of both adiponectin and vaspin were found to be significantly associated with an increased risk for endometrial cancer. Following adjustment for confounding factors, the respective odds ratios for endometrial cancer in patients in the first tertile compared with those in the third tertile were 10.80 (2.76–42.24; P=0.001) and 13.23 (2.94–59.64; P=0.001). Our results show that lower levels of circulating adiponectin and vaspin levels are associated with an increased risk of developing endometrial cancer.

Objectives: To evaluate the frequency of non-alcoholic fatty liver disease, the retinol serum levels, lipid profile, and insulin resistance in overweight/obese children. To relate these biochemical variables with the risk of this disease in the population studied. Methods: The study was cross-sectional and prospective, with 46 overweight/obese school children (28 female, 18 male; mean age 8.6 years). The control group consisted of 45 children, paired by age and gender. Hepatic steatosis, evaluated by ultrasound, was classified as normal, mild, moderate, or severe. Also evaluated were serum retinol levels; thiobarbituric acid reactive substances; lipid profile; and fasting glucose and serum insulin levels, used for the calculation of the Homeostasis Model Assessment. Results: Hepatic ultrasound alterations were found in 56.5% and 48,9% of the overweight/obese and control group children, respectively. Presence of obesity was associated with high levels of triglycerides (OR = 4.6; P = 0.002). In the studied children, the risk of steatosis was related to a trend to a higher percentage of retinol inadequacy (OR = 2.8; p = 0.051); there was no association with thiobarbituric acid reactive substances, lipid profile, or insulin resistance. Conclusions: The high frequency of non-alcoholic fatty liver disease in both groups, evaluated by hepatic ultrasound, in low-socioeconomic level children, independent of nutritional condition and without significant association with insulin resistance, emphasizes that especially in developing countries, other risk factors such as micronutrient deficiencies (e.g. vitamin A) are involved.

The association between serum concentrations of zinc, copper, or iron and the risk of metabolic syndrome are inconclusive. Therefore, we conduct a case-control study to explore the relationship between serum levels of zinc, copper, or iron and metabolic syndrome as well as each metabolic factor and insulin resistance. We enrolled 1165 adults, aged ≥ 40 (65.8 ± 10) years in a hospital-based population to compare the serum levels of zinc, copper, and iron between subjects with and without metabolic syndrome by using multivariate logistic regression analyses. The least square means were computed by general linear models to compare serum concentrations of zinc, copper, and iron in relation to the number of metabolic factors. The mean serum concentrations of zinc, copper, and iron were 941.91 ± 333.63 μg/L, 1043.45 ± 306.36 μg/L, and 1246.83 ± 538.13 μg/L, respectively. The odds ratios (ORs) of metabolic syndrome for the highest versus the lowest quartile were 5.83 (95% CI: 3.35–10.12; p for trend < 0.001) for zinc, 2.02 (95% CI: 1.25–3.25; p for trend: 0.013) for copper, and 2.11 (95% CI: 1.24–3.62; p for trend: 0.021) for iron after adjusting for age, sex, personal habits, body mass index, and homeostatic model assessment insulin resistance. Additionally, the serum zinc, copper, and iron concentrations increased as the number of metabolic factors rose (p for trend < 0.001). This was the first study to clearly demonstrate that higher serum levels of zinc, copper, and iron were associated with the risk of metabolic syndrome and the number of metabolic factors independent of BMI and insulin resistance.

Inflammatory Status

Background:Rheumatoid arthritis (RA) is associated with an increased cardiovascular (CV) risk, due not only to the traditional risk factors (hypertension, insulin resistance/diabetes, obesity, smoking), but to the inflammatory status as well. The blockade of interleukin-6 (IL-6) can regulate the glucose metabolism, reducing the glucose level and insulin resistance (IR). This beneficial effect is seen more in patients with normal values of body mass index (BMI), compared to the obese population.Objectives:Given the mentioned existing data, we aim to demonstrate the positive effect of IL-6 inhibitors in active RA patients with normal or increased BMI.Methods:We recruited 56 consecutive patients with definite and active RA, non-responders/partial responders to conventional synthetic Drug Modifying Anti-Rheumatic Drugs (csDMARDs)/biological therapy. For a period of 52 weeks, patients received subcutaneous Tocilizumab (TCZ) in a dose of 162mg once a week, according to European League Anti Rheumatism (EULAR) recommendation and National Protocol. We assessed demographics, RA-related parameters (clinical, inflammatory and immune) and metabolic markers, as well as the peripheral response to insulin, quantified by Homeostasis Model Assessment for insulin resistance (HOMA-IR) and the Quantitative Insulin Sensitivity Check Index (QUICKI). We did not include in the study the patients known with diabetes mellitus (DM) and those undergoing glucocorticoids.Results:After 52 weeks of treatment, most of the patients showed a statistically significant reduction of HOMA-IR (3.61 ± 1.21 at the onset vs. 2.45 ± 1.46 at the end of the study, p<0.001), while QUICKI registered a slight increase (0.32 ± 0.01 at the onset vs. 0.33 ± 0.01 at the end of the study, p<0.001). Also, the decrease in insulin and glucose levels were more obvious in patients with normal BMI, strictly related to disease activity.Conclusion:Long-term administration of TCZ in active RA is associated with a significant reduction of disease activity and IR, especially in normal weight patients. This confirms that obesity, as a CV risk factor, represents one of the main causes of IR.References:[1]Castañeda S, Remuzgo-Martínez S, López-Mejías R et al.

AbstractPsoriasis in adults is associated with an increased risk of metabolic disease. Various cardiometabolic comorbidities have been reported in childhood psoriasis, but only a few studies have analyzed the prevalence of metabolic syndrome. We performed a single-center prospective study investigating the prevalence of metabolic syndrome and insulin resistance in children with psoriasis. The prevalence of metabolic syndrome was evaluated in 60 pre-pubertal children with psoriasis (age: 3–10 years), accordingly to recently established criteria for the diagnosis of metabolic syndrome in children. Insulin resistance was considered altered when the homeostatic model assessment (HOMA-IR) for insulin resistance was ≥ 90th sex- and age-specific percentile and HOMA 2-IR was > 1.8. Eighteen (30%) children with psoriasis were found to have metabolic syndrome. Sixteen (27%) children were found to have insulin resistance.Conclusion: Our data underline the importance of assessing metabolic syndrome not only in adults and adolescents but also in young children with psoriasis. What is Known:• Psoriasis in adults is strongly associated with metabolic disease and insulin resistance.• Very limited data are available on the prevalence of metabolic syndrome and insulin resistance in pre-pubertal children with psoriasis. What is New:• This study reports that in pre-pubertal children with psoriasis, there is a high prevalence of metabolic syndrome and insulin resistance.• In children with psoriasis metabolic syndrome risk factors should be assessed.

Autonomic nervous system function is an important predictor of physical fitness. The objective of this study was to find out the associations of autonomic activity parameters, lipid profile, insulin concentrations, and insulin resistance in overweight men with the level of physical activity. A descriptive and correlational study was carried out in 28 overweight men: 14 physically active (PA) and 14 physically inactive (PI). The following variables were assessed: Level of physical activity, HRV (heart rate variability), basal insulin, HOMA-IR index (Homeostasis Model Assessment Insulin-Resistance), and lipid profile. The main results show a positive correlation between the spectral parameters of the HRV and total cholesterol (r = 0.24), LDL (r = 0.59), VLDL (r = 0.86), and insulin (r = 0.88) of sedentary people, evidencing a directly proportional correlation with BMI. We conclude that weight gain and a sedentary lifestyle are associated with an increase in sympathetic discharge, which, in turn, is associated with an increase in lipid profile and insulin levels.

IntroductionSystemic chronic low-grade inflammation has been linked to insulin resistance (IR) and non-alcoholic steatohepatitis (NASH). NOD-like receptor protein 3 (NLRP3) inflammasome and its final product, interleukin (IL)-1β, exert detrimental effects on insulin sensitivity and promote liver inflammation in murine models. Evidence linking hepatic NLRP3 inflammasome, systemic IR and NASH has been scarcely explored in humans. Herein, we correlated the hepatic abundance of NLRP3 inflammasome components and IR and NASH in humans.Research design and methodsMetabolically healthy (MH) (n=11) and metabolically unhealthy (MUH) (metabolic syndrome, n=21, and type 2 diabetes, n=14) subjects were recruited. Insulin sensitivity (homeostatic model assessment of IR (HOMA-IR) and Oral Glucose Sensitivity (OGIS120)), glycemic (glycated hemoglobin), and lipid parameters were determined by standard methods. Plasma cytokines were quantified by Magpix. Hepatic NLRP3 inflammasome components were determined at the mRNA and protein levels by reverse transcription–quantitative PCR and western blot, respectively. Liver damage was assessed by histological analysis (Non-alcoholic Fatty Liver Disease Activity Score (NAS) and Steatosis, Inflammatory Activity, and Fibrosis (SAF) scores). IR and liver histopathology were correlated with NLRP3 inflammasome components as well as with liver and plasma IL-1β levels.ResultsBody Mass Index, waist circumference, and arterial hypertension frequency were significantly higher in MUH subjects. These patients also had increased high-sensitivity C reactive protein levels compared with MH subjects. No differences in the plasma levels of IL-1β nor the hepatic content of Nlrp3, apoptosis-associated speck-like (Asc), Caspase-1, and IL-1β were detected between MUH and MH individuals. MUH subjects had significantly higher NAS and SAF scores, indicating more severe liver damage. However, histological severity did not correlate with the hepatic content of NLRP3 inflammasome components nor IL-1β levels.ConclusionOur results suggest that NLRP3 inflammasome activation is linked neither to IR nor to the inflammatory status of the liver in MUH patients.

Context: Irisin, a recently identified hormone, has been proposed to regulate energy homeostasis and obesity in mice. Whether irisin levels are associated with risk of the metabolic syndrome (MetS), cardiometabolic variables, and cardiovascular disease (CVD) risk in humans remains unknown. Objective: Our objective was to assess the associations between baseline serum irisin levels and MetS, cardiometabolic variables, and CVD risk. Design, Setting, and Subjects: We conducted a comparative cross-sectional evaluation of baseline circulating levels of the novel hormone irisin and the established adipokine adiponectin with MetS, cardiometabolic variables, and CVD risk in a sample of 151 subjects. Results: Baseline irisin levels were significantly higher in subjects with MetS than in subjects without MetS. Irisin was associated negatively with adiponectin (r = −0.4, P &lt; .001) and positively with body mass index (r = 0.22, P = .008), systolic (r = 0.17, P = .04) and diastolic (r = 0.27, P = .001) blood pressure, fasting glucose (r = 0.25, P = .002), triglycerides (r = 0.25, P = .003), and homeostasis model assessment for insulin resistance (r = 0.33, P &lt; .001). After adjustment for potential confounders, including body mass index, subjects in the highest tertile of irisin levels were more likely to have MetS (odds ratio [OR] = 9.44, 95% confidence interval [CI] = 2.66–33.44), elevated fasting blood glucose (OR = 5.80, 95% CI = 1.72–19.60), high triglycerides (OR = 3.89, 95% CI = 1.16–13.03), and low high-density lipoprotein cholesterol (OR = 3.30, 95% CI = 1.18–9.20). Irisin was independently associated with homeostasis model assessment for insulin resistance and general Framingham risk profile in multiple linear regression analyses after adjustment for confounders. Adiponectin demonstrated the expected associations with outcomes. Conclusions: Irisin is associated with increased risk of MetS, cardiometabolic variables, and CVD in humans, indicating either increased secretion by adipose/muscle tissue and/or a compensatory increase of irisin to overcome an underlying irisin resistance in these subjects.

Aim: To explore the association of circulating miRNAs with adiposity, metabolic status and inflammatory biomarkers in patients with metabolic syndrome (MetS). Patients & methods: Serum levels of 372 miRNAs were measured in patients with (n = 6) and without MetS (n = 6) by quantitative PCR array, and dysregulated miRNAs were validated in a larger cohort (MetS, n = 89; non-MetS, n = 144). Results: In the screening study, seven miRNAs were dysregulated in patients with MetS, and miR-421 remained increased in the validation study. miR-421 was associated with a high risk of MetS and insulin resistance and hypertension and correlated with glycated hemoglobin, triacylglycerols, high-sensitivity C-reactive protein, IL-6, resistin and adiponectin (p < 0.05). Conclusion: Circulating miR-421 is a potential biomarker for insulin resistance, metabolic dysregulation and inflammatory status in patients with MetS.
