[PMID: 34725442 DOI: 10.1038/s41366-021-00997-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 10/07/2021] [Accepted: 10/12/2021] [Indexed: 11/09/2022]
Abstract
INTRODUCTION Bariatric surgery (BS) is the most effective therapy for morbid obesity. Cortisol and DHEA are steroid hormones with opposing effects, thus using Cortisol/DHEA ratio (C/D) rather than the use of either hormone alone has been found to predict health outcomes more reliably. It was interesting to study C/D as an indicator of favorable metabolic and cardiovascular outcomes after BS. OBJECTIVE To assess C/D in morbidly obese patients before and after BS in relation to metabolic parameters and cardiovascular performance. PATIENTS AND METHODS Forty morbidly obese patients were followed prospectively for 1 year after BS. Fasting blood glucose (FBG), fasting insulin (FI), C/D, lipid profile, high-sensitive CRP (hs-CRP), and echocardiography were done before BS and at 3 months and 1 year post BS. RESULTS A total of 40 morbidly obese patients undergone sleeve gastrectomy. Blood pressure, FBG, FI, hs-CRP, C/D were significantly decreased after BS (p < 0.001). At 1 year post BS; significant reduction in left ventricular posterior wall thickness (LVPW) (p < 0.001), left ventricular mass (LVM) (p = 0.003), relative wall thickness (RWT) (p < 0.001) with a significant improvement in early diastolic velocity (E) (p < 0.001), early diastolic velocity/late diastolic velocity (E/A) (p = 0.01). After BS; C/D significantly positively correlated with FBG (p = 0.019), hs-CRP (p = 0.008), interventricular septum thickness (IVS) (p = 0.028), LVPW (p = 0.028), relative wall thickness (RWT) (p = 0.022), early diastolic velocity /early diastolic velocity (E') measured by pulsed tissue Doppler imaging (E/E') (p = 0.001), and significantly negatively correlated with E' (p = 0.032). C/D was the single significant independent variable affecting E' and E/E' post BS. CONCLUSION C/D can be used as a surrogate marker of the improved FBG and the resolution of inflammation post BS. C/D is an independent predictor of diastolic function improvement post BS.

Osei F, Block A, Wippert PM. Association of primary allostatic load mediators and metabolic syndrome (MetS): A systematic review. Front Endocrinol (Lausanne) 2022; 13:946740. [PMID: 36482995 PMCID: PMC9724739 DOI: 10.3389/fendo.2022.946740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 10/20/2022] [Indexed: 11/23/2022] Open
Abstract
Allostatic load (AL) exposure may cause detrimental effects on the neuroendocrine system, leading to metabolic syndrome (MetS). The primary mediators of AL involve serum dehydroepiandrosterone sulfate (DHEAS; a functional HPA axis antagonist); further, cortisol, urinary norepinephrine (NE), and epinephrine (EPI) excretion levels (assessed within 12-h urine as a golden standard for the evaluation of the HPA axis activity and sympathetic nervous system activity). However, the evidence of an association between the primary mediators of AL and MetS is limited. This systematic review aimed to critically examine the association between the primary mediators of AL and MetS. PubMed and Web of Science were searched for articles from January 2010 to December 2021, published in English. The search strategy focused on cross-sectional and case-control studies comprising adult participants with MetS, obesity, overweight, and without chronic diseases. The STROBE checklist was used to assess study quality control. Of 770 studies, twenty-one studies with a total sample size (n = 10,666) met the eligibility criteria. Eighteen studies were cross-sectional, and three were case-control studies. The included studies had a completeness of reporting score of COR % = 87.0 ± 6.4%. It is to be noted, that cortisol as a primary mediator of AL showed an association with MetS in 50% (urinary cortisol), 40% (serum cortisol), 60% (salivary cortisol), and 100% (hair cortisol) of the studies. For DHEAS, it is to conclude that 60% of the studies showed an association with MetS. In contrast, urinary EPI and urinary NE had 100% no association with MetS. In summary, there is a tendency for the association between higher serum cortisol, salivary cortisol, urinary cortisol, hair cortisol, and lower levels of DHEAS with MetS. Future studies focusing on longitudinal data are warranted for clarification and understanding of the association between the primary mediators of AL and MetS.

Neuropsychiatr Dis Treat 2020; 16:1051-1058. [PMID: 32368067 PMCID: PMC7184116 DOI: 10.2147/ndt.s247161] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Accepted: 03/28/2020] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Both dehydroepiandrosterone (DHEAS) and cortisol are secreted by the adrenal glands and may modulate metabolic syndrome (MetS), which often affects the health of patients with schizophrenia. The relationship between the serum levels of these hormones and MetS has not been established. PURPOSE In this pilot study, we investigated the serum levels in schizophrenia patients with and without MetS and compared them with those in healthy volunteers. PATIENTS AND METHODS After obtaining informed consent, 110 patients with acute paranoid schizophrenia were recruited directly after admission to the Mental Health Research Institute. The control group consisted of 51 persons reported on questioning to be mentally and somatically healthy. Blood samples to prepare serum were drawn after an 8-h overnight fast during one of the first days of admission. Serum cortisol and DHEAS concentrations were quantified by enzyme-linked immunosorbent assay. RESULTS A total of 42 patients had MetS and 68 patients were without MetS. The cortisol blood level was significantly (p = 0.012) higher in schizophrenia patients without MetS in comparison to healthy controls, while patients with schizophrenia and a MetS have significantly (p = 0.014) lower DHEAS levels than healthy volunteers. These differences could, however, exclusively be attributed to female participants. Analysis of covariance adjusted for gender and age demonstrated a significant relationship between age and DHEAS levels (F = 9.512, р = 0.003). CONCLUSION Lower DHEAS serum levels in relationship to MetS become evident in women, but not in men, and have age differences as a confounding factor.

Curr Aging Sci 2018; 11:126-132.

Abstract
BACKGROUND Dehydroepiandrosterone (DHEA) is an important precursor of active steroid hormone, produced abundantly by the adrenal cortex with an age-dependent pattern. OBJECTIVE We investigated whether chronic DHEA administration impacts on redox status and on Akt protein activation in skeletal muscle during the aging process (3 and 24 months-old rats). METHODS Rats received one weekly dose/5 weeks of DHEA (10 mg/kg) or vehicle. Gastrocnemius muscle was removed to evaluate glutathione system, hydrogen peroxide, antioxidant enzymes, and expression of Akt kinase protein. RESULTS In the 3-months-old rats DHEA induced an increase in hydrogen peroxide when compared both to its control (276%) and the 24-months-old DHEA group (485%). Moreover, in the 24- months-old rats DHEA caused an increase in GSSG (41 and 28%), a decrease in reduced-GSH (55 and 51%), and a more oxidized redox status (reduction in GSH/GSSG ratio, 47 and 65 %) when compared to 3-month-old DHEA and to 24-months-old control groups, respectively. Both older groups had increased G6PDH (2.7 fold) and GST (1.7 fold) activities when compared to younger groups, independently of any DHEA treatment. However, there was no modulation of Akt protein (phosphorylated/total isoform). CONCLUSION The results show that chronic DHEA administration to 3 and 24-months-old rats may not present positive effects regarding the redox environment in skeletal muscle without modulation of pro-survival Akt kinase. Due to the large-scale self-administration of DHEA as an "anti-aging" dietary supplement, it is crucial to investigate its molecular mechanisms over oxidative stressinduced related diseases.

Abstract
In developing countries the rise of obesity and obesity-related metabolic disorders, such as cardiovascular diseases and type 2 diabetes, reflects the changes in lifestyle habits and wrong dietary choices. Dietary restriction (DR) regimens have been shown to extend health span and lifespan in many animal models including primates. Identifying biomarkers predictive of clinical benefits of treatment is one of the primary goals of precision medicine. To monitor the clinical outcomes of DR interventions in humans, several biomarkers are commonly adopted. However, a validated link between the behaviors of such biomarkers and DR effects is lacking at present time. Through a systematic analysis of human intervention studies, we evaluated the effect size of DR (i.e. calorie restriction, very low calorie diet, intermittent fasting, alternate day fasting) on health-related biomarkers. We found that DR is effective in reducing total and visceral adipose mass and improving inflammatory cytokines profile and adiponectin/leptin ratio. By analysing the levels of canonical biomarkers of healthy aging, we also validated the changes of insulin, IGF-1 and IGFBP-1,2 to monitor DR effects. Collectively, we developed a useful platform to evaluate the human responses to dietary regimens low in calories.

Abstract
Castration plays a regulatory role in growth and carcass traits, particularly in fat deposition, but its molecular mechanisms are still not clear. The present study showed that castration significantly reduced the serum growth hormone and the responses of the growth hormone receptor (GHR), insulin-like growth factor 1 (IGF-I), IGF-IR and peroxisome proliferator-activated receptor gamma (PPARγ) to castration were similar in different adipose tissues. However, the GHR expression trends were opposite between the liver and the adipose tissues; bisulfite sequencing PCR (BSP) showed that its methylation in these two tissues was different. In particular, the GHR methylation rate in the liver of castrated and intact pigs were 93.33% and 0, respectively, which was consistent with its higher expression level in the intact group. It was predicted that there were potential binding sites for 11 transcription factors in the ninth CpG site (which was methylated and demethylated in subcutaneous adipose tissue of the intact and castrated groups, respectively), including androgen receptor (AR), CCAAT/enhancer binding protein-α (C/EBPα) and C/EBPβ, all of which are important factors in lipid metabolism. These results indicate that DNA methylation may participate in castration-induced fat deposition.

PLoS One 2016; 11:e0159077. [PMID: 27410429 PMCID: PMC4943648 DOI: 10.1371/journal.pone.0159077] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2016] [Accepted: 06/27/2016] [Indexed: 01/23/2023] Open
Abstract
Dehydroepiandrosterone (DHEA) has a fat-reducing effect, while little information is available on whether DHEA regulates glucose metabolism, which would in turn affect fat deposition. To investigate the effects of DHEA on glucose metabolism, rats were administered a high-fat diet containing either 0 (HCG), 25 (HLG), 50 (HMG), or 100 (HHG) mg·kg-1 DHEA per day via gavage for 8 weeks. Results showed that long-term administration of DHEA inhibited body weight gain in rats on a high-fat diet. No statistical differences in serum glucose levels were observed, whereas hepatic glycogen content in HMG and HHG groups and muscle glycogen content in HLG and HMG groups were higher than those in HCG group. Glucokinase, malate dehydrogenase and phosphofructokinase-2 activities in HMG and HHG groups, pyruvate kinase and succinate dehydrogenase activities in HMG group, and pyruvate dehydrogenase activity in all DHEA treatment groups were increased compared with those in HCG group. Phosphoenolpyruvate carboxykinase and glycogen phosphorylase mRNA levels were decreased in HMG and HHG groups, whereas glycogen synthase-2 mRNA level was increased in HMG group compared with those in HCG. The abundance of Glut2 mRNA in HMG and HHG groups and Glut4 mRNA in HMG group was higher than that in HCG group. DHEA treatment increased serum leptin content in HMG and HHG groups compared with that in HCG group. Serum insulin content and insulin receptor mRNA level in HMG group and insulin receptor substrate-2 mRNA level in HMG and HHG group were increased compared with those in HCG group. Furthermore, Pi3k mRNA level in HMG and Akt mRNA level in HMG and HHG groups were significantly increased than those in HCG group. These data showed that DHEA treatment could enhance glycogen storage and accelerate glucose catabolism in rats fed a high-fat diet, and this effect may be associated with the activation of PI3K/Akt-PFK-2 signaling pathway.
