Physical fitness and activity, metabolic profile, adipokines and endothelial function in children / Aptidão e atividade física, perfil metabólico, adipocinas e função endotelial em crianças

Abstract Objectives: The prevalence of obesity is increasing. The aim of this study was to investigate if there is endothelial dysfunction in children with normal or excess weight, and whether the metabolic profile, adipokines, and endothelial dysfunction would be more strongly associated with physical fitness or with physical activity levels. Method: Cross-sectional study involving children aged 5-12 years. The evaluation included venous occlusion plethysmography, serum levels of adiponectin, leptin and insulin, lipid profile, physical activity score (PAQ-C questionnaire), and physical fitness evaluation (Yo-Yo test). Results: A total of 62 children participated in this study. Based on the body mass index, 27 were eutrophic, 10 overweight and 25 obese. Triglycerides, LDL cholesterol, HOMA-IR, and leptin were higher in the obese and excess-weight groups compared to the eutrophic group (p < 0.01). HDL cholesterol and adiponectin levels were higher in the eutrophic group compared to the obese and excess-weight groups (p < 0.01). Flow-mediated vasodilation after hyperemia was higher in the eutrophic group in comparison to obese and excess-weight subjects (p < 0.05). There was no difference in the physical activity levels among groups measured by PAQ-C. The Yo-Yo test was significantly associated with HDL cholesterol (rho = −0.41; p = 0.01), and this association remained after adjusting for body mass index z-score (rho = 0.28; p = 0.03). Conclusion: This study showed that endothelial dysfunction is already present in obese children, suggesting a predisposition to atherosclerotic disease. Moreover, HDL cholesterol levels were correlated with physical fitness, regardless of body mass index.

Resumo: Objetivos: A prevalência da obesidade está aumentando. O objetivo deste estudo foi investigar se há disfunção endotelial nas crianças com peso normal ou excesso de peso e se o perfil metabólico, as adipocinas e a disfunção endotelial seriam mais fortemente associados à aptidão física ou aos níveis de atividade física. Método: Estudo transversal que envolve crianças de 5-12 anos. A avaliação incluiu pletismografia de oclusão venosa, níveis séricos de adiponectina, leptina, insulina e lipidograma, escore de atividade física (questionário PAQ-C) e avaliação da aptidão física (teste Yo-yo). Resultados: Um total de 62 crianças participou deste estudo. Com base no índice de massa corporal, 27 eram eutróficos, 10 estavam acima do peso e 25 estavam obesos. Os níveis de triglicerídeos, colesterol LDL, HOMA-RI e leptina estavam mais elevados nas crianças obesas e com excesso de peso que o grupo de eutróficos (p < 0,01). Os níveis de colesterol HDL e adiponectina estavam mais elevados no grupo de eutróficos em comparação ao grupo de obesos e com excesso de peso (p < 0,01). A vasodilatação mediada pelo fluxo após hiperemia foi maior no grupo de eutróficos em comparação aos indivíduos obesos e com excesso de peso (p < 0,05). Não houve nenhuma diferença nos níveis de atividade física entre os grupos medidos pelo PAQ-C. O teste de ida e volta foi significativamente associado ao colesterol HDL (ró = −0,41; p = 0,01) e essa associação continuou após ajustar o escore z do índice de massa corporal (ró = 0,28; p = 0,03). Conclusão: Este estudo mostrou que a disfunção endotelial já está presente nas crianças obesas, sugeriu uma predisposição à doença aterosclerótica. Além disso, os níveis de colesterol HDL foram correlacionados à aptidão física, independentemente do índice de massa corporal.

A Proposed Inflammatory Score of Circulating Cytokines/Adipokines Associated with Resistant Hypertension, but Dependent on Obesity Parameters / Proposta de um Escore Inflamatório de Citocinas e Adipocinas Plasmáticas Associado à Hipertensão Resistente, mas Dependente dos Parâmetros de Obesidade

Abstract Background: There is evidence that subclinical systemic inflammation is present in resistant hypertension (RHTN). Objective: The aim of the study was to develop an integrated measure of circulating cytokines/adipokines involved in the pathophysiology of RHTN. Methods: RHTN (n = 112) and mild to moderate hypertensive (HTN) subjects (n=112) were studied in a cross-sectional design. Plasma cytokines/adipokines (TNF-alpha, interleukins [IL]-6, -8, -10, leptin and adiponectin) values were divided into tertiles, to which a score ranging from 1 (lowest tertile) to 3 (highest tertile) was assigned. The inflammatory score (IS) of each subject was the sum of each pro-inflammatory cytokine scores from which anti-inflammatory cytokines (adiponectin and IL-10) scores were subtracted. The level of significance accepted was alpha = 0.05. Results: IS was higher in RHTN subjects compared with HTN subjects [4 (2-6) vs. 3 (2-5); p = 0.02, respectively]. IS positively correlated with body fat parameters, such as body mass index (r = 0.40; p < 0.001), waist circumference (r = 0.30; p < 0.001) and fat mass assessed by bioelectrical impedance analysis (r = 0.31; p < 0.001) in all hypertensive subjects. Logistic regression analyses revealed that IS was an independent predictor of RHTN (OR = 1.20; p = 0.02), independent of age, gender and race, although it did not remain significant after adjustment for body fat parameters. Conclusion: A state of subclinical inflammation defined by an IS including TNF-alpha, IL-6, IL-8, IL-10, leptin and adiponectin is associated with obese RHTN. In addition, this score correlates with obesity parameters, independently of hypertensive status. The IS may be used for the evaluation of conditions involving low-grade inflammation, such as obesity-related RHTN. Indeed, it also highlights the strong relationship between obesity and inflammatory process.

Resumo Fundamento: Evidências indicam que a inflamação sistêmica subclínica está presente na hipertensão arterial resistente (HAR). Objetivo: Desenvolver uma medida que integra citocinas envolvidas na fisiopatologia da HAR. Métodos: Indivíduos com HAR (n = 112) e indivíduos com hipertensão leve a moderada (HT) (n = 112) foram estudados em delineamento transversal. Valores de citocinas/adipocinas plasmáticas [TNF-alfa, interleucinas (IL)-6, -8, -10, leptina e adiponectina] foram divididos em tercis, e lhes atribuído um escore variando de 1 (tercil mais baixo) a 3 (tercil mais alto). O escore inflamatório (EI) de cada participante foi calculado como a soma do escore de cada citocina pró-inflamatória da qual subtraiu-se o escore de cada citocina anti-inflamatória (adiponectina e IL-10). O nível de significância aceito foi alfa = 0,05. Resultados: O EI foi mais alto nos indivíduos com HAR em comparação a indivíduos com HT [4 (2-6) vs. 3 (2-5); p = 0,02, respectivamente]. O EI correlacionou-se positivamente com parâmetros de gordura corporal, tais como índice de massa corporal (r = 0,40; p < 0,001), circunferência da cintura (r = 0,30; p < 0,001) e massa gorda avaliada por bioimpedância (r = 0,31; p < 0,001) em todos os indivíduos hipertensos. Análises de regressão logística mostraram que o EI foi um preditor independente de HAR (OR = 1,20; p = 0,02), independentemente de idade, sexo e raça; porém, o modelo perdeu significância estatística após ajuste para os parâmetros de gordura corporal. Conclusão: Um estado de inflamação subclínica definida pelo EI incluindo TNF-alfa, IL-6, IL-8, IL-10, leptina e adiponectina está associado com indivíduos obesos com HAR. Além disso, o escore correlaciona-se com parâmetros de obesidade, independentemente do grau de hipertensão. O EI pode ser usado na avaliação de condições que envolvem inflamação subclínica, tal como HAR relacionada à obesidade. O estudo também destaca a forte relação entre obesidade e inflamação.

Adipokine gene variability and plasma levels in patients with chronic periodontitis -a case-control study

Abstract: Specific variants in genes that encode adipokines and their mRNA and protein expression were previously studied in type 2 diabetes mellitus (T2DM) and obesity, and similar studies have been performed for chronic periodontitis (CP). The aim of this case-control study was to investigate the possible impacts of adiponectin (ADIPOQ), leptin (LEP) and its receptor (LEPR), and resistin (RETN) on the etiopathogenesis of CP. Examinations were performed on 118 non-periodontitis healthy subjects (healthy controls, HC), 205 healthy individuals with CP (H + CP) and 86 type 2 diabetes patients with CP (T2DM + CP). Variants within the ADIPOQ (rs2241766, rs1501299), LEP (rs13228377, rs2167270), LEP receptor (rs1805096), and RETN (rs1862513) genes were determined by qPCR. In addition, the plasma levels of ADIPOQ, LEP, and RETN were analysed by ELISA for 80 individuals. The genotype frequencies of the SNP ADIPOQ +45G/T (rs2241766) differed between the HC and H + CP groups (p=0.03, pcorr>0.05), and carriers of the TT genotype had a lower risk of developing CP compared to carriers of the GG or TG genotypes (p<0.01, pcorr>0.05). However, there were no significant differences in the plasma levels of ADIPOQ, LEP or RETN between the study groups (p > 0.05). Plasma levels of the adipokines were also independent of the gene profiles (p > 0.05). Adipokine plasma levels did not change in patients with H + CP/T2DM + CP compared to HC, but we did identify a specific polymorphism in the ADIPOQ gene that was associated with CP. Although the ADIPOQ +45G/T (rs2241766) gene variant may be a candidate biomarker for CP, further research is required in larger populations with different ethnic backgrounds before any final conclusions can be drawn about the role of this gene in CP.

Correlações entre características da doença hepática gordurosa não-alcoólica e os níveis de adipocinas e citocinas inflamatórias em indivíduos submetidos à cirurgia bariátrica / Correlation between nonalcoholic fatty liver disease features and levels of adipokines and inflammatory cytokines among morbidly obese individuals

ABSTRACT BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the commonest hepatopathy worldwide. OBJECTIVE: To investigate the correlations between NAFLD histopathological features and the levels of adipokines (adiponectin, leptin, and resistin) and circulating inflammatory markers (interleukin-6 [IL-6], interleukin-8 [IL-8], tumor necrosis factor alpha [TNF-α], and C-reactive protein [CRP]). METHODS: This is an exploratory cross-sectional study, which enrolled 19 women with obesity who underwent bariatric surgery. Biochemical characteristics evaluated included the levels of adiponectin, leptin, resistin, IL-6, IL-8, TNF-α, and CRP. NAFLD was assessed through histological examination of liver biopsies carried out during the surgical procedures. RESULTS: The mean age of the study group was 37.3±8.2 years old; mean BMI was 36.2±2.5 kg/m2. Among individuals with liver fibrosis, the levels of IL-8 were significantly higher (24.4 ± 9.7 versus 12.7 ± 6.6; P=0.016726). The intensity of fibrosis presented a significant negative correlation with the levels of adiponectin (R= -0.49379; P=0.03166); i.e. the higher the levels of adiponectin, the lower the intensity of fibrosis. The intensity of steatohepatitis presented a significant negative correlation with the levels of adiponectin (R= -0.562321; P=0.01221); this means that the higher the levels of adiponectin, the lower the intensity of steatohepatitis. CONCLUSION: Adiponectin levels were inversely correlated with the severity of fibrosis and steatohepatitis, whereas IL-8 levels were higher in individuals with liver fibrosis among individuals with obesity and NAFLD undergoing bariatric surgery. The use of these markers to assess NAFLD may bring significant information within similar populations.

RESUMO CONTEXTO: A doença hepática gordurosa não-alcoólica (DHGNA) é a hepatopatia mais comum no mundo. OBJETIVO: Investigar correlações entre as apresentações histopatológicas da DHGNA e os níveis de adipocinas (adiponectina, leptina e resistina) e marcadores sistêmicos de inflamação (interleucina-6 [IL-6], interleucina-8 [IL-8], fator de necrose tumoral alfa [TNF-α] e proteína C reativa [PCR]). MÉTODOS: Estudo transversal exploratório envolvendo 18 mulheres com obesidade submetidas à cirurgia bariátrica. As características bioquímicas avaliadas incluíram os níveis de adiponectina, leptina, resistina, IL-6, IL-8, TNF-α e PCR. A DHGNA foi avaliada através de exams histológicos de biópsias hepáticas realizadas durantes as cirurgias. RESULTADOS: A idade média foi 37,3±8,2 anos; o índice de massa corporal (IMC) médio foi 36,2±2,5 kg/m2. Entre os indivíduos com fibrose hepática, os níveis de IL-8 foram significativamente mais altos (24,4±9,7 versus 12,7±6,6; P=0,016726). A intensidade da fibrose apresentou uma correlação negativa significativa com os níveis de adiponectina (R= -0,49379; P=0,03166), demonstranso que, quanto maiores os níveis de adiponectina, menor a intensidade da fibrose. A intensidade da esteato-hepatite apresentou uma correlação negativa significativa com os níveis de adiponectina (R= -0,562321; P=0,01221), demonstrando que quanto mais altos os níveis de adiponectina, menor a intensidade da esteato-hepatite. CONCLUSÃO: Os níveis de adiponectina correlacionaram-se negativamente com a severidade da fibrose e da esteato-hepatite, enquanto os níveis de IL-8 foram maiores entre os indivíduos com fibrose hepática. O uso destes marcadores pode trazer informações significativas sobre a DHGNA em populações com obesidade.

Inflammatory biomarkers responses after acute whole body vibration in fibromyalgia

The aims of this study were 1) to characterize the intensity of the vibration stimulation in women diagnosed with fibromyalgia (FM) compared to a control group of healthy women (HW) matched by age and anthropometric parameters, and 2) to investigate the effect of a single session of whole body vibration (WBV) on inflammatory responses. Levels of adipokines, soluble tumor necrosis factor receptors (sTNFr1, sTNFr2), and brain-derived neurotrophic factor (BDNF) were determined by enzyme-linked immunosorbent assay. Oxygen consumption (VO2) was estimated by a portable gas analysis system, heart rate (HR) was measured using a HR monitor, and perceived exertion (RPE) was evaluated using the Borg scale of perceived exertion. Acutely mild WBV increased VO2 and HR similarly in both groups. There was an interaction (disease vs vibration) in RPE (P=0.0078), showing a higher RPE in FM compared to HW at rest, which further increased in FM after acute WBV, whereas it remained unchanged in HW. In addition, there was an interaction (disease vs vibration) in plasma levels of adiponectin (P=0.0001), sTNFR1 (P=0.000001), sTNFR2 (P=0.0052), leptin (P=0.0007), resistin (P=0.0166), and BDNF (P=0.0179). In conclusion, a single acute session of mild and short WBV can improve the inflammatory status in patients with FM, reaching values close to those of matched HW at their basal status. The neuroendocrine mechanism seems to be an exercise-induced modulation towards greater adaptation to stress response in these patients.

Comparison of body composition and adipokine levels between thin and normal-weight prepubertal children / Comparação da composição corporal e dos níveis de adipocina entre crianças pré-púberes magras e com peso normal

Abstract Objective: Thinness can have substantial consequences for child development and health. Adipokines, including leptin and adiponectin, play a significant role in the regulation of important metabolic functions. The aim of this study was to investigate associations between body composition and serum leptin and adiponectin levels in thin and normal-weight children. Methods: The authors examined 100 healthy prepubertal children, who were divided into two subgroups: thin (n = 50) and normal-weight children (n = 50). Body composition was assessed by dual-energy X-ray absorptiometry. Serum concentrations of adipokines were determined by immunoenzymatic assays. Results: Thin children had a similar body height but significantly lower (p < 0.0001) body weight, body mass index, fat mass, lean mass, and bone mineral content compared with normal-weight children. Serum concentrations of leptin were about 2-fold lower (p < 0.0001) in thin vs. normal-weight subjects. Serum levels of total adiponectin, adiponectin multimers, and soluble leptin receptor (sOB-R) were similar in both groups. The leptin/soluble leptin receptor ratio and leptin/adiponectin ratios were lower (p < 0.0001) in thin vs. normal-weight children. In both groups of children, it was found that body composition parameters were positively related with leptin but not with adiponectin levels. Additionally, bone mineral content was positively related with body mass index, fat mass, lean mass, and leptin level in thin and normal-weight children. Conclusions: Prepubertal thin children have disturbances in body composition and adipokine profile. Early recognition of thinness and determination of body composition parameters and adipokine levels can be useful in medical and nutritional care of thin children for the optimization of bone mineral accrual.

Resumo Objetivo: A magreza pode ter consequências substanciais para o desenvolvimento e a saúde das crianças. As adipocinas, inclusive a leptina e a adiponectina, desempenham um papel significativo na regulação de importantes funções metabólicas. O objetivo do estudo foi investigar as associações entre a composição corporal e os níveis séricos de leptina e adiponectina em crianças magras e com peso normal. Métodos: Examinamos 100 crianças pré-púberes saudáveis, divididas em dois subgrupos: crianças magras (n = 50) e com peso normal (n = 50). A composição corporal foi avaliada pelo método de absorciometria de dupla energia de raios X. As concentrações séricas das adipocinas foram determinadas por ensaios imunoenzimáticos. Resultados: As crianças magras apresentaram altura semelhante, porém peso corporal (p < 0,0001), índice de massa corporal (IMC), massa gorda, massa magra e conteúdo mineral ósseo (CMO) significativamente menores em comparação com crianças com peso normal. As concentrações séricas de leptina foram aproximadamente duas vezes mais baixas (p < 0,0001) em indivíduos magros do que em crianças com peso normal. Os níveis séricos de adiponectina total, multímeros de adiponectina e receptor de leptina solúvel (sOB-R) foram semelhantes em ambos os grupos. Os índices de leptina/sOB-R e leptina/adiponectina foram inferiores (p < 0,0001) em crianças magras do que crianças com peso normal. Em ambos os grupos de crianças descobrimos que os parâmetros de composição corporal estavam positivamente relacionados à leptina, porém não aos níveis de adiponectina. Além disso, observamos que o CMO estava positivamente relacionado ao IMC, à massa gorda, à massa magra e ao nível de leptina em crianças magras e com peso normal. Conclusões: As crianças pré-púberes magras têm alterações na composição corporal e no perfil de adipocinas. O reconhecimento precoce da magreza e a determinação dos parâmetros de composição corporal e dos níveis de adipocina podem ser úteis no cuidado médico e nutricional de crianças magras para aprimoramento do acúmulo mineral ósseo.

Correlation between adipokines and carotid intima media thickness in a group of obese Romanian children: is small for gestational age status an independent factor for cardiovascular risk?

ABSTRACT Objective To investigate the relationship between markers of adiposity and common carotid artery (CIMT) in obese children born small for gestational age (SGA) versus appropriate for gestational age (AGA), to establish cut-off values for CIMT in obese pediatric populations. Subjects and methods A cross-sectional study was carried out over a 1-year period (Jul 2013 – June 2014). We analyzed 122 obese patients aged 4-20 (mean age 14.9 ± 2.28). Twenty-six patients were born SGA. CIMT was measured in all the patients. Using ROC curve, cut-off values were obtained for both groups. Results We demonstrated a correlation between CIMT and adiponectin, leptin and high sensitivity C-reactive protein (hsCRP) (r = -0.25, r = 0.279, r = 0.498) in obese children. CIMT in obese children born SGA were significantly increased as compared with obese children born AGA of similar age, sex and body mass index (BMI) (p = 0.0035). A CIMT cut off value of 0.049 cm has been obtained with a high sensitivity and specificity. Conclusion CIMT is a well-known marker of subclinical atherosclerosis and its measurement is a noninvasive and inexpensive method of detecting subclinical atherosclerosis. Being born SGA increases the atherogenic risk. Obese children with CIMT above 0.049 cm should be screened for metabolic syndrome (MetS).

Glycemic control and adipokines after periodontal therapy in patients with Type 2 diabetes and chronic periodontitis

Abstract: The mechanism by which chronic periodontitis (CP) affects type 2 diabetes (T2DM) remains unclear. Therefore, the aim of this study is to evaluate the effects of periodontal therapy (PT) on the glycemic control and adipokines of patients with T2DM and CP with the purpose of elucidating the possible mechanisms by which CP influences T2DM. Forty-four patients with T2DM and CP were randomly divided into two groups according to whether they underwent PT. Periodontal status, blood glucose, and the levels of serum tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), adiponectin (APN), and fibroblast growth factor-21 (FGF-21) were measured at baseline and after 3 months. The results revealed that the probing depth (PD) and attachment loss (AL) were significantly improved, the serum levels of TNF-α and IL-6 were significantly decreased, and APN and FGF-21 exhibited substantial increases in the intervention group after 3 months (p < 0.05), whereas no significant changes were observed in the control group. The glycated hemoglobin (HbA1c) levels in both groups decreased significantly after 3 months compared with baseline (p < 0.05), but the intervention group exhibited a significantly greater change (p < 0.05). In conclusion, PT may relieve periodontal inflammation, which causes a reduction of insulin-antagonizing adipokines and an increase in insulin-sensitizing adipokines, thereby eliciting an improvement in glycemic control.

[Adipolin and insulin resistance response to two types of exercise training in type 2 diabetic male rats]

Introduction: Adipolin [CTRP12], which improves insulin sensitivity, is a novel anti-inflammatory adipocytokine secreted from adipose tissue. In this study we aimed to assess the Adipolin and Insulin Resistance index [HOMA-IR] response to two types of exercise in type 2 diabetic male rats

Materials and Methods: In this study, 24 diabetic Wistar rats [Induced by high-fat diet and Streptozotocin[stz] injection] were randomly assigned to 3 groups: High intensity interval exercise [HIIT], low intensity continuous training [LICT] and control [C]. Both training groups were trained on the treadmill, 5 sessions per week for 8 weeks. Blood samples were taken 24 hours after the end of training session and plasma adipolin, insulin and glucose levels were measured. ANOVA and Tukey post hoc tests were used to analyze data and the level of significance was considered to be p60.05

Results: Data analysis showed that plasma adipolin levels in the low intensity continuous training group were significantly increased, compared to the control group [p=0.006]. Plasma glucose level in both the low intensity continuous training and the high intensity interval groups was significantly decreased, compared to the control group [p=0.049] and [p=0.007]. Plasma insulin level in both training groups was increased and HOMA-IR index was decreased, compared to the control group, although changes were not significant

Conclusion: The results of this study showed that exercise training can increase plasma adipolin in rats with type 2 diabetes, changes however that are partially dependent on the type of exercise training

Serum adipocytokine profile and metabolic syndrome in young adult female dermatomyositis patients

OBJECTIVES: To analyse the frequency of metabolic syndrome in young adult female dermatomyositis patients and its possible association with clinical and laboratory dermatomyositis-related features and serum adipocytokines. METHOD: This cross-sectional study included 35 dermatomyositis patients and 48 healthy controls. Metabolic syndrome was defined according to the 2009 Joint Interim Statement. RESULTS: Patient age was comparable in the dermatomyositis and control groups, and the median disease duration was 1.0 year. An increased prevalence of metabolic syndrome was detected in the dermatomyositis group (34.3% vs. 6.3%; p=0.001). In addition, increased serum adiponectin and resistin levels were noted in contrast to lower leptin levels. In dermatomyositis patients, adipocytokine levels were correlated with the levels of total cholesterol, low-density cholesterol, triglycerides and muscle enzymes. A comparison of dermatomyositis patients with (n=12) and without (n=23) syndrome metabolic revealed that adipocytokine levels were also correlated with age, and that dermatomyositis patients with metabolic syndrome tended to have more disease activity despite similar adipocytokine levels. CONCLUSIONS: Metabolic syndrome is highly prevalent in young adult female dermatomyositis patients and is related to age and disease activity. Moreover, increased serum adiponectin and resistin levels were detected in dermatomyositis patients, but lower serum leptin levels were observed.

Early changes in adipokines from overweight to obesity in children and adolescents / Alterações precoces nos níveis de adipocinas de sobrepeso para obesidade em crianças e adolescentes

Abstract Objective: Childhood obesity has been associated with metabolic syndrome and cardiovascular diseases. This study aimed to compare plasma levels of traditional metabolic markers, adipokines and soluble tumor necrosis factor receptor type 1 (sTNFR1) in overweight, obese and lean children. We also assessed the relationships of these molecules with classical metabolic risk factors. Methods: This study included 104 children and adolescents, which were grouped as: lean (n = 24), overweight (n = 30), and obese subjects (n = 50). They were subjected to anthropometrical, clinical and laboratorial measurements. All measurements were compared between groups. Correlation analyses were also performed to evaluate the association between clinical data, traditional metabolic markers, adipokines and sTNFR1. Results: Fasting glucose, insulin, homeostatic model assessment of insulin resistance (HOMA-IR), LDL-cholesterol and triglycerides were comparable in lean, overweight and obese subjects. Plasma levels of sTNFR1 were similar in lean and overweight subjects, but significantly increased in obese group. Leptin, adiponectin and resistin levels did not differ when overweight were compared to obese subjects. However, all adipokines differed significantly when lean subjects were compared to overweight and obese individuals. Plasma levels of adiponectin were negatively correlated with body mass index (BMI), whereas leptin, resistin and sTNFR1 concentrations positively correlated with BMI. Conclusion: Our results showed significant differences in circulating levels of the evaluated markers when lean, overweight and obese individuals were compared, suggesting that these biomarkers may change from lean to overweight and from overweight to obesity.

Resumo Objetivo: A obesidade na infância tem sido associada à síndrome metabólica e a doenças cardiovasculares. O objetivo deste estudo foi comparar níveis plasmáticos de marcadores metabólicos tradicionais, adipocinas e do receptor solúvel de fator de necrose tumoral tipo 1 (sTNFR1) em crianças com sobrepeso, obesas e magras. Também avaliamos as relações dessas moléculas com fatores de risco metabólico clássicos. Métodos: Este estudo incluiu 104 crianças e adolescentes, agrupados da seguinte forma: indivíduos magros (n = 24), com sobrepeso (n = 30) e obesos (n = 50). Eles foram submetidos a medições antropométricas, clínicas e laboratoriais. Todas as medições foram comparadas entre os grupos. Também foram feitas análises de correlação para avaliar a associação entre dados clínicos, marcadores metabólicos tradicionais, adipocinas e sTNFR1. Resultados: Glicemia de jejum, insulina, modelo de avaliação da homeostase da resistência à insulina (HOMA-IR), colesterol LDL e triglicerídeos foram comparáveis em indivíduos magros, com sobrepeso e obesos. Os níveis plasmáticos de sTNFR1 foram similares em indivíduos magros e com sobrepeso, porém significativamente maiores no grupo obeso. Os níveis de leptina, adiponectina e resistina não diferiram quando indivíduos com sobrepeso foram comparados aos obesos. Contudo, todas as adipocinas diferiram significativamente quando indivíduos magros foram comparados a indivíduos com sobrepeso e obesos. Os níveis plasmáticos de adiponectina estavam negativamente correlacionados ao índice de massa corporal (IMC), ao passo que as concentrações de leptina, resistina e sTNFR1 estavam positivamente correlacionadas ao IMC. Conclusão: Nossos resultados mostraram diferenças significativas nos níveis circulantes dos marcadores avaliados ao comparar indivíduos magros, com sobrepeso e obesos. Isso sugere que esses biomarcadores poderão mudar de indivíduos magros para indivíduos com sobrepeso e de indivíduos com sobrepeso para obesos.

Serum Adipokine Levels and their Relationship with Fatty Acids in Patients with Chronic Periodontitis

Adipokines are present in inflammatory processes and may be directly related to periodontal disease. Moreover, their activities may be regulated by fatty acids. The goal of this study was to quantify the concentrations of the main adipokines, leptin, adiponectin and resistin, and the docosahexaenoic (DHA), docosapentaenoic (DPA), eicosapentaenoic (EPA) and arachidonic (AA) fatty acids, in patients with generalized chronic periodontitis. As a secondary objective, the ratios of these substances in the blood of these patients were evaluated. The study included 15 systemically healthy patients with generalized chronic periodontitis (test group) and 15 patients with gingivitis (control group). Medical and periodontal parameters and blood samples were collected. Serum concentrations of fatty acids were analyzed by gas chromatography and adipokines by multiplex bead immunoassay. There was no significant difference in adipokines between groups. However, there was a tendency for lower values of adiponectin in periodontitis patients. Regarding the fatty acids, they were significantly higher in the test group compared with controls. The res/DHA, res/AA, adipon/DHA, adipon/AA and adipon/DPA ratios were significantly lower in the test group. There was no significant correlation between adipokines and clinical parameters and between adipokines and fatty acids levels. It was concluded that generalized chronic periodontitis patients showed significantly higher levels of fatty acids in comparison to gingivitis; adiponectin revealed a trend to lower values in the periodontitis group, even after Ancova correction. The ratios suggest a minor proportion of adiponectin and resistin in relation to the fatty acids in patients with generalized chronic periodontitis.

As adipocinas estão presentes em processos inflamatórios e podem estar diretamente relacionadas à doença periodontal. Além disso, suas atividades podem ser reguladas pelos ácidos graxos. Este estudo teve como objetivo quantificar as concentrações das principais adipocinas, leptina, adiponectina e resistina, e dos ácidos graxos: ácido docosahexaenóico (DHA), ácido docosapentaenóico (DPA), ácido eicosapentaenóico (EPA) e ácido araquidônico (AA), em pacientes com periodontite crônica generalizada. Como objetivo secundário, avaliar as proporções destas substâncias no sangue desses pacientes. O estudo incluiu 15 pacientes sistemicamente saudáveis com periodontite crônica generalizada (grupo teste) e 15 com gengivite (grupo controle). Foram coletados parâmetros médicos e periodontais e amostras de sangue. As concentrações séricas dos ácidos graxos foram analisadas por cromatografia gasosa e as das adipocinas foram analisadas pelo método multiensaio multiplex. Não houve diferença significativa entre os níveis de adipocinas entre os grupos. No entanto, houve uma tendência para menores valores nos níveis da adiponectina nos pacientes com periodontite. Com relação aos ácidos graxos, os valores foram significativamente maiores no grupo teste em comparação com os controles. As razões entre res/DHA, res/AA, adipon/DHA, adipon/AA e adipon/DPA foram significativamente menores no grupo teste. Não houve correlação significativa entre as adipocinas e os parâmetros clínicos e entre os níveis de adipocinas e ácidos graxos. Conclui-se que pacientes com periodontite crônica generalizada apresentaram níveis significativamente maiores de ácidos graxos em relação à gengivite, adiponectina apresentou uma tendência a valores menores no grupo periodontite, mesmo após a correção de Ancova. Os resultados das razões sugerem uma menor proporção de adiponectina e resistina em relação aos ácidos graxos em pacientes com periodontite crônica generalizada.

Efeito do tratamento periodontal não-cirúrgico sobre o controle glicêmico, mediadores inflamatórios e adipocinas em pacientes com diabetes mellitus tipo 2 e periodontite crônica severa / Effect of non-surgical periodontal treatment on glycemic control, inflammatory mediators and adipokines in patients with type 2 diabetes and severe chronic periodontitis

O objetivo do presente estudo foi avaliar o efeito do tratamento periodontal não cirúrgico sobre o controle glicêmico e os níveis séricos de adipocinas e mediadores inflamatórios em pacientes com periodontite crônica e diabetes mellitus tipo 2 (DM2). Foram selecionados 41 pacientes com periodontite crônica severa e com DM2, que foram aleatoriamente alocados em dois grupos: o grupo teste (21 pacientes, idade média de 58,1 ± 8,4 anos, 11 homens e 10 mulheres), que foram submetidos ao tratamento periodontal não cirúrgico; e o grupo controle (20 pacientes, idade média de 54,1 ± 9,9 anos, 14 homens e 6 mulheres), que permaneceram sem tratamento periodontal. Os parâmetros clínicos (profundidade de sondagem ­ PS, nível de inserção clínica ­ NIC, SS - sangramento à sondagem e índice de placa ­ IP), os laboratoriais (hemoglobina glicada ­ HbA1c, colesterol total ­ CT, HDL, LDL e triglicerídeos) e os marcadores inflamatórios (interleucinas - 1ß e -6, fator de necrose tumoral-α, resistina, leptina e adiponectina) foram avaliados inicialmente (dia 0) e 90 dias após a terapia periodontal. Os resultados obtidos indicaram uma redução na % dos sítios com SS, IP e nos sítios com PS ≥ 6mm no grupo teste (P <0.05). Os níveis de HbA1c, glicose estimada, IL-1ß, TNF-α e resistina também diminuíram significativamente neste grupo. Os demais marcadores não tiveram alterações significantes em ambos os grupos. Concluindo, o tratamento periodontal não cirúrgico da periodontite crônica severa foi associado à melhora do controle glicêmico e à diminuição nos níveis de IL-1ß, TNF-α e resistina após 3 meses, em pacientes com diabetes mellitus tipo 2.

The aim of this study was to evaluate the effects of non-surgical periodontal treatment on glycemic control, adipokines and systemic inflammatory mediators levels in patients with severe chronic periodontitis and diabetes mellitus type 2 (DM2). Fourty-one patients with severe chronic periodontitis and DM2 were randomly allocated in the test group (21 patients, mean age 58.1 ± 8.4 years, 11 men and 10 women) underwent nonsurgical periodontal treatment; and the control group (20 patients, mean age 54.1 ± 9.9 years, 14 men and 6 women) who remained untreated. The clinical parameters (probing depth - PD, clinical attachment level - CAL, BOP- bleeding on probing and plaque index - PI), laboratory (glycated hemoglobin - HbA1c, total cholesterol - TC, HDL, LDL and triglycerides) and inflammatory mediators (interleukin - 1ß and -6, tumor necrosis factor-α, resistin, leptin and adiponectin) were evaluated at baseline and 90 days after periodontal therapy. After 90 days, there was a reduction in the% of sites with BOP, PI and sites with PD ≥ 6 mm in the test group. HbA1c levels, estimated glucose, IL-1ß, TNF-α and resistin also significantly decreased in this group. There were no significant changes in the other markers in both groups. In conclusion, non-surgical periodontal treatment improved glycemic control in patients with severe chronic periodontitis and DM2. IL-1ß, TNF-α and resistin levels decreased significantly after 3 months of the treatment.

Serum adipokine concentrations in dogs with diabetes mellitus: a pilot study

This study was conducted to determine whether serum adipokine concentrations differed between healthy dogs and dogs with diabetes mellitus (DM). To accomplish this, 19 dogs with newly diagnosed DM were compared to 20 otherwise healthy dogs. The serum concentrations of visfatin, leptin, IL-1beta, IL-6, IL-18, and TNF-alpha were significantly higher in diabetic dogs than in healthy dogs, whereas the serum adiponectin concentrations were lower in diabetic dogs. However, there were no significant differences in the IL-10 and resistin levels between groups. The serum leptin concentrations in diabetic dogs with and without concurrent disorders differed significantly. Treatment with insulin induced a significant decrease in IL-6 in diabetic dogs without concurrent disorders. These results show that the clinical diabetic state of dogs could modulate the circulating visfatin and adiponectin concentrations directly, while upregulation of leptin was probably a result of concurrent disorders rather than an effect of persistent hyperglycemia as a result of DM.

Métodos: Avaliaram-se 116 indivíduos, sendo 63 homes, pertencentes ao estudo do Rio de Janeiro (seguimento 17,76 ± 1,63 anos) em dois momentos: A1 (12,40 ± 1,49 anos) e A2 (30,09 ± 2,01 anos). Os 116 indivíduos foram divididos em dois grupos: GN (n = 71), PA normal em A1; e GH (n = 45): PA anormal em A1. A PA, o peso, a altura e o índice de massa corporal (IMC) foram obtidos em A1 e A2. Em A2, acrescentaram-se a circunferência abdominal (CA) e variáveis laboratoriais, metabólicas e inflamatórias. Resultados: 1) Os grupos não diferiram quanto à idade e sexo; 2) Em A2, GH apresentou maiores médias de peso, IMC, PA, insulina, HOMA-IR (p < 0,001), leptina (p < 0,02), Apolipoproteína B100 e A1 (p < 0,02), relação Apolipoproteína B100 / Apolipoproteína A1 (p < 0,010), maiores prevalências de sobrepeso/obesidade (p < 0,001), da CA aumentada (p < 0,001) e de hipertensão arterial (p < 0,02); 3) Não houve diferença entre os grupos para as variáveis inflamatórias; 4) Houve correlação positiva da PA em A1 com a PA, o IMC, e com a insulina, a leptina e o HOMA-IR em A2 (p < 0,05). Conclusões: A PA na adolescência se associou a maiores valores de PA, variáveis antropométricas e metabólicas na fase adulta jovem, mas não a variáveis inflamatórias. .

Background: The impact of blood pressure (BP) during adolescence on other cardiovascular risk factors in young adults is important for the primary prevention. Objective: To evaluate BP, anthropometric indexes, metabolic and inflammatory profiles in young individuals stratified by their BP behavior recorded for 18 years. Methods: A total of 116 individuals, of whom 63 were males, from the Rio de Janeiro study (follow-up of 17.76 ± 1.63 years), were assessed at two moments: A1 (12.40 ± 1.49 years) and A2 (30.09 ± 2.01 years). The 116 individuals were divided into two groups: GN (n = 71), of participants with normal BP at A1; and GH (n = 45), of those with abnormal BP at A1. BP, weight, height and body mass index (BMI) were measured at A1 and A2. At A2, abdominal circumference (AC) and laboratory, metabolic and inflammatory variables were included. Results: 1) No difference was observed between the groups as regards age and gender; 2) At A2, GH showed higher mean weight, BMI, BP, insulin, HOMA-IR (p < 0.001), leptin (p < 0.02), apolipoprotein B100 and A1 (p < 0.02), apolipoprotein B100 / apolipoprotein A1 ratio (p < 0.010); and higher prevalences of overweight/obesity (p < 0.001), of increased AC (p < 0.001) and of hypertension (p < 0.02); 3) No difference was observed between the groups as regards the inflammatory variables; 4) There was a positive correlation of BP at A1 with BP, BMI, insulin, leptin and HOMA-IR at A2 (p < 0.05). Conclusion: BP in adolescence was associated with higher values of BP, and anthropometric and metabolic variables in young adulthood, but not with inflammatory variables. .

Measurement of antioxidant capacity using the biological antioxidant potential test and its role as a predictive marker of metabolic syndrome

BACKGROUND/AIMS: Oxidative stress increases the risk of cardiovascular complications of metabolic syndrome (MetS). This study was conducted to examine the difference in antioxidant capacity according to the presence of MetS, and to characterize the association between antioxidant capacity and MetS-related factors. METHODS: We used the biological antioxidant potential (BAP) test to estimate antioxidant capacity. The BAP test has recently been used as an indicator of antioxidant capacity. We measured BAP levels in 45 patients with MetS (mean age, 44.6 +/- 1.1 years) and 47 age- and sex-matched controls (mean age, 42.7 +/- 1.1 years). To evaluate the association between antioxidant capacity and MetS, adiponectin, high-sensitivity C-reactive protein (hs-CRP), interleukin-6, tumor necrosis factor-alpha, and homeostatic model assessment for insulin resistance (HOMA-IR), linear regression and logistic analyses were performed. RESULTS: The mean BAP of the MetS group (1,937.3 +/- 36.5 micromol/L) was significantly lower than that of the non-MetS group (2,101.7 +/- 29.5 micromol/L). Also, the mean BAP was low in persons having low high density lipoprotein and high triglyceride. Reduced antioxidant capacity was significantly associated with adiponectin, HOMA-IR and hs-CRP after adjusting for age and sex. The odds ratios for MetS with BAP, log adiponectin, log HOMA-IR, and log hs-CRP were 0.63 (95% confidence interval [CI], 0.49 to 0.82), 0.22 (0.10 to 0.51), 14.24 (4.35 to 46.58), and 1.93 (1.36 to 2.75), respectively. CONCLUSIONS: Persons with MetS showed reduced antioxidant capacity. We identified relationships between antioxidant capacity measured by BAP test and MetS, as well as MetS-related factors, such as insulin resistance, hs-CRP, and adiponectin.

Velocidade da onda de pulso, pressão arterial e adipocitocinas em adultos jovens: estudo do Rio de Janeiro / Pulse wave velocity, blood pressure and adipocytokines in young adults: the Rio de Janeiro study

FUNDAMENTO: Dados sobre a avaliação não invasiva vascular e suas relações com variáveis de risco cardiovascular são escassos em jovens. OBJETIVO: Avaliar a relação entre a velocidade de onda de pulso e a pressão arterial,variáveis antropométricas e metabólicas, incluindo as adipocitocinas, em indivíduos adultos jovens. MÉTODOS: Foram avaliados 96 indivíduos (51 homens) do estudo do Rio de Janeiro, de 26 a 35 anos (média 30,09 ± 1,92). Foram obtidos a velocidade de onda de pulso (método Complior), pressão arterial, índice de massa corporal, glicose, perfil lipídico, leptina, insulina, adiponectina e o índice de resistência à insulina HOMA-IR. Os indivíduos foram estratificados em três grupos segundo o tercil da VOP para cada sexo. RESULTADOS: O grupo com maior tercil de VOP mostrou maiores médias de pressão arterial sistólica, pressão arterial diastólica, pressão arterial média, índice de massa corporal, insulina, HOMA-IR e menores médias de adiponectina, além de maiores prevalências de diabetes mellitus/intolerância à glicose e hiperinsulinemia. Houve correlação significativa e positiva da velocidade da onda de pulso com pressão arterial sistólica, pressão arterial diastólica, pressão de pulso e pressão arterial média, índice de massa corporal, e LDL-colesterol e negativa com HDL-colesterol e adiponectina. Em modelo de regressão múltipla, após ajuste do HDL-colesterol, LDL-colesterol e adiponectina para sexo, idade, índice de massa corporal e pressão arterial média, apenas o sexo masculino e a pressão arterial média mantiveram correlação significativa com a velocidade de onda de pulso. CONCLUSÃO: A velocidade de onda de pulso em adultos jovens mostrou relação significativa com variáveis de risco cardiovascular, destacando-se o sexo masculino e a pressão arterial média como importantes variáveis no seu determinismo. Os achados sugerem que a medida da VOP pode ser útil para a identificação do acometimento vascular nessa faixa etária.

BACKGROUND: Data on noninvasive vascular assessment and their association with cardiovascular risk variables are scarce in young individuals. OBJECTIVE: To evaluate the association between pulse wave velocity and blood pressure, anthropometric and metabolic variables, including adipocytokines, in young adults. METHODS: A total of 96 individuals aged 26 to 35 years (mean 30.09 ± 1.92; 51 males) were assessed in the Rio de Janeiro study. Pulse wave velocity (Complior method), blood pressure, body mass index, glucose, lipid profile, leptin, insulin, adiponectin and insulin resistance index (HOMA-IR) were analyzed. Subjects were stratified into three groups according to the PWV tertile for each gender. RESULTS: The group with the highest pulse wave velocity (PWV) tertile showed higher mean systolic and diastolic blood pressure, mean blood pressure, body mass index, insulin, and HOMA-IR, as well as lower mean adiponectin; higher prevalence of diabetes mellitus/glucose intolerance and hyperinsulinemia. There was a significant positive correlation of PWV with systolic blood pressure, diastolic blood pressure, pulse pressure and mean blood pressure, body mass index, and LDL-cholesterol, and a negative correlation with HDL-cholesterol and adiponectin. In the multiple regression model, after adjustment of HDL-cholesterol, LDL-cholesterol and adiponectin for gender, age, body mass index and mean blood pressure, only the male gender and mean blood pressure remained significantly correlated with PWV. CONCLUSION: PWV in young adults showed a significant association with cardiovascular risk variables, especially in the male gender, and mean blood pressure as important determinant variables. The findings suggest that PWV measurement can be useful for the identification of vascular impairment in this age group.

[ effect of resistance training on serum levels of adipokine and inflammatory markers of cardiovascular disease in obese men]

Recent studies on endocrine function have revealed many pathological complications in relation to obesity and metabolic diseases. Thus, the present study was carried out with the aim of investigating the effect of 12-week resistance training on the serum levels adipokine [adiponectin and leptin] and inflammatory markers of cardiovascular diseases in obese men. In this semi-experimental study, 20 non-athlete obese men were randomly assigned to two groups of experimental and control. The experimental group performed the resistance training protocol, three sessions per week for 12 weeks, while the control group was prohibited to do training program during the research implementation. Five ml of venous blood was taken from the participants at the beginning of the sixth week and at the end of the twelfth week to measure leptin, adiponectin, CRP, IL-6, and TNF-alpha. The significance level was considered to be alpha<0.05. Resistance training caused decrease in CRP [p=0.002], IL-6 [p=0.001] and leptin [p=0.002], and increase in adiponectin [p=0.001] in the experimental group compared to the control group. Also, TNF-alpha level showed a decrease in the experimental group after 12 weeks of resistance training, which was not statically significant. The results of this study showed that regular resistance trainings reduce the potential risk of cardiovascular diseases via improvement of the plasma levels of adiponectin, leptin, CRP, and IL-6, and it can be used as an effective nonpharmacological treatment to prevent these diseases
