ABSTRACT Background The onset of menopause increases the risk of metabolic syndrome (MetS). Adiponectin is an adipokine associated with insulin sensitivity that is lower in people with MetS. Supplementing diets with linoleic acid (LA)-rich oil increased adiponectin concentrations and improved glucose control in women with type 2 diabetes. The effect of LA on adipokines, especially total and the bioactive form of adiponectin, high-molecular-weight (HMW) adiponectin, in women with MetS is unknown. Objectives The aim of this study was to explore the effect of supplementation of the diet with an oil rich in LA on adipokines in women with MetS. The effect of the LA-rich oil (LA-oil) on oxylipins, key metabolites that may influence inflammation and metabolism, was also explored. Methods In this open-label single-arm pilot study, 18 postmenopausal nondiabetic women with MetS enrolled in a 2-phase study were instructed to consume LA-rich vegetable oil (10 mL/d) as part of their habitual diets. Women consumed an oleic acid–rich oil (OA-oil) for 4 wk followed by an LA-oil for 16 wk. Fasting concentrations of adipokines, fatty acids, oxylipins, and markers of glycemia and inflammation were measured. Results After 4 wk of OA-oil consumption, fasting glucose and total adiponectin concentrations decreased whereas fasting C-reactive protein increased. After 16 wk of LA-oil supplementation total and HMW adiponectin and plasma oxylipins increased. Markers of inflammation and glycemia were unchanged after LA-oil consumption. Conclusions Supplementation with LA-oil increased total and HMW adiponectin concentrations and altered plasma oxylipin profiles. Larger studies are needed to elucidate the links between these changes and MetS. This trial was registered at clinicaltrials.gov as NCT02063165.

Abstract Context: Japanese are prone to obesity-induced metabolic derangement, which is linked to serum adipocytokine profile even in children. Objective: The objective of the study was to determine whether high molecular-weight adiponectin (H-Adn) more specifically relates to metabolic derangement in obese children than total adiponectin (T-Adn). Design and Setting: A case (n = 59) control (n = 28) study was performed at the pediatric clinic of a university hospital. Patients: Japanese obese children (38 boys and 21 girls) were consecutively enrolled. The ages ranged from 5 to 15 (10.3 ± 0.3; mean ± sem) yr. Nonobese children (15 boys and 13 girls) were assigned as age-matched controls. Main Outcome Measures: Serum adiponectin multimeric complexes were assayed by an ELISA kit. The relationship of adiponectin to metabolic abnormalities was evaluated. Results: T-Adn (5.1 ± 0.2 vs. 8.8 ± 0.4 μg/ml), H-Adn (1.3 ± 0.1 vs. 4.8 ± 0.4 μg/ml), and medium molecular weight-Adn were significantly lower in obese than in control children. After adjustment for age and sex, both T- and H-Adn were inversely correlated with insulin and homeostasis model of assessment-insulin resistance, whereas H-Adn (but not T-Adn) inversely correlated with visceral fat area, as determined by computed tomography. Seven obese children were estimated to have metabolic syndrome and showed selective decrease in H-Adn and H/T-Adn. Conclusion: H-Adn reflects metabolic abnormalities due to obesity better than T-Adn in children. H-Adn is associated with the development of metabolic syndrome, even in childhood.

AbstractIn many studies, high-molecular-weight (HMW) adiponectin has been considered the active form of adiponectin. However, whether HMW adiponectin is a good surrogate marker for coronary artery disease still needs to be elucidated.We conducted a hospital-based cross-sectional study to examine the relationship between total, HMW or non-HMW adiponectin concentrations and coronary stenosis in 83 male patients and 138 male controls.Patients with coronary stenosis had significantly lower total adiponectin concentrations compared with controls. Non-HMW adiponectin concentrations in cases were significantly lower than the controls. However, there were no significant differences between cases and controls in HMW adiponectin concentrations. From the receiver operating characteristic (ROC) analysis, the area under the curve (AUC) for total and non-HMW adiponectin was significantly larger than that for HMW adiponectin concentrations. Of the three models, that for non-HMW adiponectin showed the largest AUC (total adiponectin 0.74, HMW adiponectin 0.54, and non-HMW adiponectin 0.79).Despite associations between total adiponectin levels and coronary stenosis, our data go against any apparent association between HMW adiponectin concentrations and coronary stenosis.

Circulating Levels

Abstract It has been hypothesized that the observed excess risk of multiple myeloma (MM) among obese persons could be the result of altered circulating levels of adipokines, polypeptide hormones with pro- and anti-inflammatory properties secreted by adipose tissue. We investigated whether circulating levels of leptin, total adiponectin, and high molecular weight adiponectin are associated with subsequent MM risk among 174 MM patients and 348 controls within the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. Inverse associations with MM were observed for total adiponectin (highest quartile vs lowest: odds ratio = 0.49; 95% CI = 0.26-0.93, Ptrend = .03) and high molecular weight adiponectin (0.44; 0.23-0.85, Ptrend = .01). These associations remained after restricting to MM patients diagnosed ∼ 8 years or more after blood collection. Leptin levels were not associated with MM risk. The results of this study, to our knowledge the first prospective investigation of circulating adipokines and MM, suggest that adiponectin may play an important role in obesity-related myelomagenesis.

ObjectivePreeclampsia (PE) is a serious cardiovascular complication in pregnancy which is associated with an increased future metabolic and cardiovascular risk for mother and newborn. Recently, a paradoxical upregulation of the insulin-sensitizing and anti-atherogenic adipokine adiponectin has been shown in PE. Furthermore, high-molecular-weight (HMW) adiponectin has been suggested as the biologically active form of this adipokine.Design and methodsHMW adiponectin and total adiponectin serum concentrations were quantified by ELISA in PE (n=16) patients and pregnant control women without PE (n=20). Furthermore, HMW adiponectin and total adiponectin were correlated to clinical and biochemical measures of renal function, glucose, and lipid metabolism, as well as inflammation.ResultsMedian maternal HMW adiponectin and total adiponectin levels were significantly and independently upregulated almost twofold in PE when compared with controls. HMW adiponectin and total adiponectin correlated positively with creatinine and negatively with fasting insulin in univariate and multivariate analyses.ConclusionsWe show that maternal HMW adiponectin and total adiponectin serum concentrations are significantly increased in PE and are positively associated with markers of insulin sensitivity and renal dysfunction. Adiponectin might be part of a physiological feedback mechanism improving insulin sensitivity and cardiovascular health in PE.

The study aimed at assessing the potential use of lower total and HMW adiponectin levels for predicting cardiovascular risk in patients with type 2 diabetes mellitus (T2DM). Concentrations of total adiponectin or high molecular weight (HMW) adiponectin decrease in association with the development of metabolic dysfunction such as obesity, insulin resistance, or T2DM. Increased adiponectin levels are associated with a lower risk for coronary heart disease. A total of 551 individuals were assessed. The first group comprised metabolically healthy participants (143 females, and 126 males) and the second group were T2DM patients (164 females, and 118 males). Both total adiponectin and HMW adiponectin in diabetic patients were significantly lower when compared with the group of metabolically healthy individuals. There was a weak monotonic correlation between HMW adiponectin levels and triglycerides levels. Binary logistic regression analysis, gender adjusted, showed a higher cardiovascular risk in diabetic persons when both total adiponectin (OR = 1.700) and HMW adiponectin (OR = 2.785) levels were decreased. A decrease in total adiponectin levels as well as a decrease in its HMW adiponectin is associated with a higher cardiovascular risk in individuals with T2DM. This association suggests that adiponectin levels may be potentially used as an epidemiological marker for cardiovascular risk in diabetic patients.
