Abstract
In 2016, the World Health Organization estimated that more than 1.9 billion adults were overweight or obese. This impressive number shows that weight excess is pandemic. Overweight and obesity are closely associated with a high risk of comorbidities, such as insulin resistance and its most important outcomes, including metabolic syndrome, type 2 diabetes mellitus, and cardiovascular disease. Adiponectin has emerged as a salutary adipocytokine, with insulin-sensitizing, anti-inflammatory, and cardiovascular protective properties. However, under metabolically unfavorable conditions, visceral adipose tissue-derived inflammatory cytokines might reduce the transcription of the adiponectin gene and consequently its circulating levels. Low circulating levels of adiponectin are negatively associated with various conditions, such as insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. In contrast, several recent clinical trials and meta-analyses have reported high circulating adiponectin levels positively associated with cardiovascular mortality and all-cause mortality. These results are biologically intriguing and counterintuitive, and came to be termed "the adiponectin paradox". Adiponectin paradox is frequently associated with adiponectin resistance, a concept related with the downregulation of adiponectin receptors in insulin-resistant states. We review this contradiction between the apparent role of adiponectin as a health promoter and the recent evidence from Mendelian randomization studies indicating that circulating adiponectin levels are an unexpected predictor of increased morbidity and mortality rates in several clinical conditions. We also critically review the therapeutic perspective of synthetic peptide adiponectin receptors agonist that has been postulated as a promising alternative for the treatment of metabolic syndrome and type 2 diabetes mellitus.

Prospective Study of Sex-Specific Adiponectin Changes and Incident Metabolic Syndrome: The ARIRANG Study. J Clin Med 2019; 8:jcm8050599. [PMID: 31052455 PMCID: PMC6571573 DOI: 10.3390/jcm8050599] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Revised: 04/28/2019] [Accepted: 04/29/2019] [Indexed: 01/22/2023] Open
Abstract
We investigated whether changes in adiponectin levels over time predict incident metabolic syndrome (MetS) in a population-based prospective study. In total, 1110 subjects were categorized into four groups according to their sex-specific median baseline adiponectin levels and the change in adiponectin levels at follow-up: low baseline adiponectin and decreased adiponectin during follow-up (LB&DF), low baseline adiponectin and increased adiponectin during follow-up (LB&IF), high baseline adiponectin and decreased adiponectin during follow-up (HB&DF), and high baseline adiponectin and increased adiponectin during follow-up (HB&IF). During the median 2.4-year follow-up period, 180 (16.2%) subjects developed MetS. Compared to the LB&DF group, the fully adjusted hazard ratio (95% confidence interval) for incident MS was the lowest in the HB&IF group (0.33, (0.17–0.63)), followed by the HB&DF group (0.58, (0.40–0.84)) and LB&IF group (0.63, (0.41–0.93)). This phenomenon was more prominent in men than in women. Among the individual MetS components, increased adiponectin levels during follow-up were significantly associated with lower risks of incident low high density lipoprotein (HDL) cholesterol and incident high blood pressure. This finding suggests that a change in adiponectin level, as well as the baseline adiponectin level, might have a clinical role in the development of MetS among men.

Abstract
Resistant hypertension (RHTN) is a multifactorial and polygenic disease, frequently associated with obesity. Low plasma adiponectin levels, a hormone produced by the adipose tissue, were associated with RHTN. Single nucleotide polymorphisms (SNPs) -11377C/G (rs266729) and +276G/T (rs1501299) in ADIPOQ (adiponectin gene) were associated with hypertension. This study evaluated the association between two SNPs (-11377C/G and +276G/T) and adiponectin levels in RHTN. This study comprised 109 patients with RHTN genotyped for both polymorphisms. A cross-sectional study was designed to compare features of CC homozygous versus G allele carriers for -11377C/G and GG homozygous versus T allele carriers for +276G/T. Office and ambulatory BP measurements were similar among genotypes subgroups in both SNPs as well as the markers of target organ damage (arterial stiffness, left ventricular mass index and microalbuminuria). Adiponectin concentrations were significantly higher in CC compared to G carrier for -11377C/G (CC:7.0 (4.0-10.2) versus G allele:5.5 (2.5-7.9), p = 0.04) and lower in GG compared to T carrier for +276G/T (GG:5.3 (2.3-7.7) versus T allele:7.1 (3.6-10.5), p = 0.04). Adjusting for systolic ambulatory BP, body mass index, age, gender, race and presence of type 2 diabetes, multiple linear regression analyses revealed that the minor alleles G (β-coefficient= -0.14, SE=0.07, p = 0.03) and T (β-coefficient=0.12, SE=0.06, p = 0.04) were independent predictors of adiponectin. The -11377C/G and +276G/T SNPs in ADIPOQ were associated with adiponectin levels in RHTN individuals.

Abstract
AIMS The aim of this study was to investigate the association between serum adiponectin level and new-onset hypertension, and the relative contribution of obesity and low serum adiponectin levels to the development of hypertension in normotensive men and women. METHODS We analyzed 1553 adults (584 men and 969 women) without hypertension, aged 40-70 years, who had participated in a cohort study in both time periods from 2005 to 2008 for baseline and 2008 to 2011 for follow-up. We divided participants into sex-specific tertiles according to serum adiponectin levels. We defined the highest tertile of serum adiponectin as 'high adiponectin'. Participants were then stratified into four groups: the non-obese with high adiponectin; the non-obese with low adiponectin; the obese with high adiponectin; and the obese with low adiponectin. RESULTS During an average of 2.6 years of follow-up, 79 men (13.5%) and 99 women (10.2%) developed hypertension. Low serum adiponectin level was an independent predictor of new-onset hypertension in men (Odds Ratio[OR]: 1.99; 95% CI: 1.03-3.86). The Obese men with low adiponectin had an increased risk of new-onset hypertension compared with the control group (OR: 2.80; 95% CI: 1.35-5.81). In postmenopausal women, the obese subjects with low adiponectin had an increased risk of new-onset hypertension compared with the control group (OR: 2.41; 95% CI 1.16-5.04). CONCLUSION Low serum adiponectin levels were associated with an increased risk of new-onset hypertension in men and postmenopausal women.

The renin-angiotensin system in adipose tissue and its metabolic consequences during obesity. J Nutr Biochem 2013; 24:2003-15.

Abstract
Obesity is a worldwide disease that is accompanied by several metabolic abnormalities such as hypertension, hyperglycemia and dyslipidemia. The accelerated adipose tissue growth and fat cell hypertrophy during the onset of obesity precedes adipocyte dysfunction. One of the features of adipocyte dysfunction is dysregulated adipokine secretion, which leads to an imbalance of pro-inflammatory, pro-atherogenic versus anti-inflammatory, insulin-sensitizing adipokines. The production of renin-angiotensin system (RAS) components by adipocytes is exacerbated during obesity, contributing to the systemic RAS and its consequences. Increased adipose tissue RAS has been described in various models of diet-induced obesity (DIO) including fructose and high-fat feeding. Up-regulation of the adipose RAS by DIO promotes inflammation, lipogenesis and reactive oxygen species generation and impairs insulin signaling, all of which worsen the adipose environment. Consequently, the increase of circulating RAS, for which adipose tissue is partially responsible, represents a link between hypertension, insulin resistance in diabetes and inflammation during obesity. However, other nutrients and food components such as soy protein attenuate adipose RAS, decrease adiposity, and improve adipocyte functionality. Here, we review the molecular mechanisms by which adipose RAS modulates systemic RAS and how it is enhanced in obesity, which will explain the simultaneous development of metabolic syndrome alterations. Finally, dietary interventions that prevent obesity and adipocyte dysfunction will maintain normal RAS concentrations and effects, thus preventing metabolic diseases that are associated with RAS enhancement.

Abstract
Obesity and HTN are on the rise in the world. HTN seems to be the most common obesity-related health problem and visceral obesity seems to be the major culprit. Unfortunately, only 31% of hypertensives are treated to goal. This translates into an increased incidence of CVD and related morbidity and mortality. Several mechanisms have been postulated as the causes of obesity-related HTN. Activation of the RAAS, SNS, insulin resistance, leptin, adiponectin, dysfunctional fat, FFA, resistin, 11 Beta dehydrogenase, renal structural and hemodynamic changes, and OSA are some of the abnormalities in obesity-related HTN. Many of these factors are interrelated. Treatment of obesity should begin with weight loss via lifestyle modifications, medications, or bariatric surgery. According to the mechanisms of obesity-related HTN, it seems that drugs that blockade the RAAS and target the SNS should be ideal for treatment. There is not much evidence in the literature that one drug is better than another in controlling obesity-related HTN. There have only been a few studies specifically targeting the obese hypertensive patient, but recent trials that emphasize the importance of BP control have enrolled both overweight and obese subjects. Until we have further studies with more in-depth information about the mechanisms of obesity-related HTN and what the targeted treatment should be, the most important factor necessary to control the obesity-related HTN pandemic and its CVD and CKD consequences is to prevent and treat obesity and to treat HTN to goal.

Abstract
Adiponectin is an adipocyte-derived protein that is down-regulated in obesity-linked disorders. Variants of the adiponectin gene (ADIPOQ) have been shown to affect adiponectin level. We have now examined the relation of polymorphisms of ADIPOQ to adiponectin concentration and to metabolic disorders in the Kita-Nagoya Genomic Epidemiology study, a population-based study of elderly Japanese. The genomic region including ADIPOQ was genotyped for 30 single nucleotide polymorphisms in 500 subjects of a screening population with the use of a fluorescence- or colorimetry-based allele-specific DNA primer-probe assay system. Four polymorphisms were then selected for genotyping in an additional 2797 subjects. Serum adiponectin level was negatively associated with metabolic abnormalities after adjustment for age and sex. The minor alleles of the rs1656930, Ile164Thr, and rs9882205 polymorphisms were associated with a low serum adiponectin level. Whereas the minor alleles of rs1656930 and rs9882205 were common (minor allele frequency of 6.2 and 38.5%, respectively), that of Ile164Thr was rare (0.9%). The minor allele of rs1656930 was positively associated with systolic blood pressure and the prevalence of hypertension. The association of rs1656930 with adiponectin level was replicated in an independent population. A subject with the 164Thr/Thr genotype had an extremely low serum adiponectin level (0.6 μg/ml) and the phenotype of metabolic syndrome. Our results suggest that a common variant of ADIPOQ, the minor allele of rs1656930, is associated with hypoadiponectinemia and hypertension. Screening for a common genetic background underlying low adiponectin levels might provide important information for assessment and management of metabolic disorders.

Abstract
BACKGROUND Considering that prehypertension is associated with an increase in cardiovascular risk, hypoadiponectinemia seems to be a predictor of hypertension. HYPOTHESIS This study investigated whether adiponectin plasma levels are affected in Brazilian obese prehypertensives compared with those in normotensives and hypertensives. METHODS The study involved 96 multiethnic obese subjects (mean age = 42.8-11.9 years; BMI = 35.7-7.3 kg/m(2)). Fasting plasma adiponectin and serum insulin were determined by radioimmunoassay. Insulin resistance was estimated by HOMA-IR. Blood pressure was recorded using a calibrated automated sphygmomanometer. RESULTS Adiponectin concentrations were significantly lower in prehypertensives compared with those in normotensives, but hypertensives exhibited the lowest adiponectin concentrations of all. Regarding the values of HOMA-IR, both prehypertensives and hypertensives were significantly more insulin resistant when compared with normotensives. When normotensives and prehypertensives were classified according to the 50th percentile of adiponectin (< or = vs > 6.5 mg/ml) a logistic regression was performed to estimate the association of this adipokine with hypertension, the lower the plasma adiponectin values, the greater the association. A multivariate linear regression analysis adjusted for cardiometabolic factors showed that systolic blood pressure increased by 1.612 mm Hg for 1 microg/mL reduction in adiponectin plasma levels (P < 0.01). CONCLUSION Our findings have shown that hypoadiponectinemia is associated with prehypertension in obese individuals of multiethnic origin.

Abstract
OBJECTIVE To examine whether insulin, leptin and adiponectin are independent correlates of blood pressure (BP) in a large population-based sample of children and adolescents. METHODS We studied 655 boys and 667 girls aged 9, 13 and 16 years who participated in the Quebec Child and Adolescent Health and Social Survey, a province-wide school-based survey conducted in 1999. RESULTS Strong, positive univariate associations between BMI, insulin and leptin Z-scores, and both systolic and diastolic BP were found in both sexes. Adiponectin Z-scores were negatively associated with systolic BP in girls only. In multivariate analyses only BMI and insulin Z-scores were significantly associated with systolic BP. In boys, each 1 SD increase in BMI was associated with a 4 mmHg increase in mean systolic BP; each 1 SD increase in insulin was associated with a 1 mmHg increase in mean systolic BP. Only insulin Z-scores were independently associated with diastolic BP in both sexes. For each 1 SD increase in insulin, there was a 1 mmHg increase in mean diastolic BP in boys. Similar to systolic BP, the magnitude of the effect of insulin Z-scores on diastolic BP increased as a function of BMI Z-scores in girls. CONCLUSION Independently of BMI, insulin is a strong correlate of systolic and diastolic BP in youth. Although animal studies support a role for leptin and adiponectin in controlling BP, they are not independently associated with BP in youth.

Abstract
Arterial hypertension is a global public health problem owing to its high prevalence and association with increased risk for cerebral, cardiac and renal events. Hypertension frequently clusters with other cardiometabolic risk factors, such as dysglycemia, low levels of high-density lipoprotein cholesterol and high triglyceride levels. These, along with other factors such as central obesity, increased inflammation, endothelial dysfunction and thrombosis, are components of the metabolic syndrome. All guidelines recommend that the first-line therapy in metabolic syndrome should be based on lifestyle modification, consisting of diet and moderate exercise for at least 30 min/day. Concerning drug treatment of hypertension associated with other cardiometabolic risk factors, many results of head-to-head studies have demonstrated a reduction in new-onset Type 2 diabetes in hypertensive patients treated with angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, when compared with conventional antihypertensive therapy. The explanations of the different actions of both these drugs include several mechanisms related to pancreatic insulin release and insulin sensitivity improvement. Another mechanism by which the inhibition of the renin-angiotensin system may improve insulin sensitivity is through the partial peroxisome proliferator-activated receptor-gamma agonism of telmisartan. For that reason, telmisartan has been considered by some experts to be an antihypertensive agent that is particularly useful in the treatment of hypertension associated with cardiometabolic risk factors. The impact of the promising metabolic action exhibited by telmisartan on the outcome of hypertensive patients aggregating other cardiometabolic risk factors waits for adequately randomized and powered clinical trials.
