Abstract
Sarcopenia is a chronic, progressive skeletal muscle disease characterised by low muscle strength and quantity or quality, leading to low physical performance. Patients with type 2 diabetes mellitus (T2DM) are more at risk of sarcopenia than euglycemic individuals. Because of several shared pathways between the two diseases, sarcopenia is also a risk factor for developing T2DM in older patients. Various biomarkers are under investigation as potentially valuable for sarcopenia diagnosis and treatment monitoring. Biomarkers related to sarcopenia can be divided into markers evaluating musculoskeletal status (biomarkers specific to muscle mass, markers of the neuromuscular junction, or myokines) and markers assuming causal factors (adipokines, hormones, and inflammatory markers). This paper reviews the current knowledge about how diabetes and T2DM complications affect potential sarcopenia biomarker concentrations. This review includes markers recently proposed by the expert group of the European Society for the Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) as those that may currently be useful in phase II and III clinical trials of sarcopenia: myostatin (MSTN); follistatin (FST); irisin; brain-derived neurotrophic factor (BDNF); procollagen type III N-terminal peptide (PIIINP; P3NP); sarcopenia index (serum creatinine to serum cystatin C ratio); adiponectin; leptin; insulin-like growth factor-1 (IGF-1); dehydroepiandrosterone sulphate (DHEAS); C-reactive protein (CRP); interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α). A better understanding of factors influencing these biomarkers' levels, including diabetes and diabetic complications, may lead to designing future studies and implementing results in clinical practice.

Accelerated telomere shortening in adrenal zona reticularis in patients with prolonged critical illness. Front Endocrinol (Lausanne) 2023; 14:1244553. [PMID: 37745694 PMCID: PMC10512174 DOI: 10.3389/fendo.2023.1244553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 08/18/2023] [Indexed: 09/26/2023] Open
Abstract
Background The number of patients with prolonged critical illness (PCI) has been increasing in many countries, and the adrenal gland plays an important role in maintaining homeostasis during PCI. Chronic disease burden is reportedly associated with shorter telomere lengths in human tissues. Telomere shortening in human somatic cells is largely dependent on cell divisions, and critically short telomeres lead to cellular dysfunction and aging. However, the association between PCI and telomere lengths in human adrenal cells is poorly understood. In this study, we investigated this association to assess whether the burden of PCI could accelerate the aging process in adrenal cells. Methods Adrenocortical tissues from patients who died after PCI usually show a diffuse pattern of intracellular cholesterol ester depletion (i.e., lipid depletion). This study examined near-normal adrenal glands obtained from autopsied patients who died suddenly (control group) and lipid-depleted adrenal glands obtained from autopsied patients who died after PCI (PCI group). The control group included 7 men aged 80 to 94 years (mean age: 85.3 years) and 7 women aged 84 to 94 years (mean age: 87.7 years). The PCI group included 10 men aged 71 to 88 years (mean age: 78.8 years) and 8 women aged 77 to 95 years (mean age: 85.6 years). By using quantitative fluorescence in situ hybridization, relative telomere lengths (RTLs) were determined in the parenchymal cells of the three adrenocortical zones (zona glomerulosa, zona fasciculata, and zona reticularis [ZR]) and in the chromaffin cells of the medulla. The number of adrenal parenchymal cells was determined by immunohistochemistry and digital image analysis. Results RTLs in ZR cells were significantly shorter in the PCI group than in the control group for both men and women (P = 0.0001 for men and P = 0.0012 for women). However, RTLs in the remaining three types of adrenal cells did not differ between the control and PCI groups for both men and women. The number of ZR cells was higher in the PCI group than in the control group for both men and women (P < 0.0001 for both men and women). The proportion of the number of ZR cells to the total number of adrenocortical parenchymal cells was also higher in the PCI group than in the control group (P < 0.0001 for both men and women). The Ki-67 proliferation index in ZR cells was higher in the PCI group than in the control group (P = 0.0039 for men and P = 0.0063 for women). Conclusions This study demonstrated ZR cell-specific telomere shortening in patients with adrenal lipid depletion who died after PCI. Our results suggest that the reactive proliferation of ZR cells accelerates the telomere shortening and aging process in ZR cells in these patients. The results of our study may contribute to the understanding of adrenal aging during PCI.

Abstract
Background The associations of dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) with diabetic kidney disease (DKD) remained unclear. Thus, this cross-sectional study aimed to explore the associations of DHEA and DHEAS with the risk of DKD in patients with T2DM. Methods The information of 1251 patients with T2DM were included in this study. Serum DHEA and DHEAS were quantified using liquid chromatography-tandem mass spectrometry assays. Multivariate logistic regression analyses were used to assess the associations of DHEA and DHEAS with DKD as well as high urine albumin to creatinine ratio (ACR). Results In men with T2DM, the risk of DKD decreased with an increasing DHEA concentration after adjustment for traditional risk factors; the fully adjusted OR (95% CI) for tertile3 vs tertile1 was 0.37 (0.19-0.70; P = 0.010 for trend). Similarly, when taking high ACR as the outcome, low DHEA levels were still significantly associated with increased odds of high ACR (OR, 0.37; 95% CI, 0.19-0.72 for tertile3 vs tertile1; P = 0.012 for trend). The restricted cubic spline showed that the risk of DKD gradually decreased with the increment of serum DHEA levels (P-overall = 0.007; P-nonlinear = 0.161). DHEAS was not independently associated with the risk of DKD in men. In contrast, no significant relationships were found between DHEA and DHEAS and the risk of DKD in women (all P > 0.05). Conclusions In men with T2DM, low serum DHEA levels were independently related to the risk of DKD after adjustment for traditional risk factors. Our finding highlights the potential role of DHEA in the development of DKD in men with T2DM.

Elevated circulating luteinizing hormone levels are associated with diabetic macroalbuminuria in Chinese men and postmenopausal women: A cross-sectional study. J Diabetes 2020; 12:819-833. [PMID: 32475064 DOI: 10.1111/1753-0407.13073] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 05/16/2020] [Accepted: 05/27/2020] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Associations between sex hormones and diabetic vascular complications have recently been studied, but the role luteinizing hormone (LH) plays in diabetic kidney disease (DKD) remains uncertain. We aimed to investigate the relationship of LH and DKD in Chinese men and postmenopausal women with type 2 diabetes mellitus (T2DM). METHODS Data were collected from 1775 T2DM men and postmenopausal women in hospital. The odds ratios (OR) and corresponding 95% confidence intervals (CI) in relation to LH quartiles were obtained by multiple logistic regression analysis. RESULTS LH levels were significantly higher in patients with macroalbuminuria than in those with microalbuminuria, but were not higher in patients with microalbuminuria than in those with normoalbuminuria. Consistently, LH in those with an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73m2 were significantly higher than in those with eGFR≥60 mL/min/1.73m2 . The prevalence of macroalbuminuria was obviously increased for subjects of the fourth quartile of LH vs the first to third quartile (20.4% vs 6.2%, 8.0%, 12.2% in men; 25.3% vs 5.5%, 3.8%, 9.3% in postmenopausal women). Multivariate logistic regression demonstrated that subjects within the highest quartile of LH had higher odds of macroalbuminuria than those within the lowest quartile (OR 4.00, 95% CI, 1.87-8.55 for men; OR 9.62, 95% CI, 3.42-27.08 for postmenopausal women), independent of age, diabetes duration, or other metabolic factors. The area under the curve for detecting macroalbuminuria based on LH was 0.662 for men, and 0.767 for postmenopausal women. CONCLUSION High LH levels are positively associated with established DKD among Chinese men and postmenopausal women. Elevated LH may be a promising clinical factor for identifying established DKD.

Abstract
Dehydroepiandrosterone (DHEA), mostly present as its sulfated ester (DHEA-S), is an anabolic hormone that naturally declines with age. Furthermore, it is the most abundant androgen and estrogen precursor in humans. Low plasma levels of DHEA have been strongly associated with obesity, insulin resistance, dyslipidemia, and high blood pressure, increasing the risk of cardiovascular disease. In this respect, DHEA could be regarded as a promising agent against metabolic syndrome (MetS) in postmenopausal women, since several age-related metabolic diseases are reported during aging. There are plenty of experimental evidences showing beneficial effects after DHEA therapy on carbohydrate and lipid metabolism, as well as cardiovascular health. However, its potential as a therapeutic agent appears to attract controversy, due to the lack of effects on some symptoms related to MetS. In this review, we examine the available literature regarding the impact of DHEA therapy on adiposity, glucose metabolism, and the cardiovascular system in the postmenopausal period. Both clinical studies and in vitro and in vivo experimental models were selected, and where possible, the main cellular mechanisms involved in DHEA therapy were discussed. Schematic representation showing some of the general effects observed after administration DHEA therapy on target tissues of energy metabolism and the cardiovascular system. ↑ represents an increase, ↓ represents a decrease, - represents a worsening and ↔ represents no change after DHEA therapy.

Abstract
Introduction: In assessing the development of hyperuricemia in diabetic adults, the role of the sex steroid axis is underappreciated. Furthermore, dehydroepiandrosterone (DHEA) has been recommended as a nutritional supplement. However, is DHEA suitable for diabetic adults with hyperuricemia? This issue has received little attention. Aim: The objective of this study was to investigate the associations between gonadal hormones and uric acid (UA) levels in diabetic adults, paying particular attention to the association between DHEA and UA levels. Methods: We analyzed 4,426 participants out of 4,813 diabetic adults enrolled from seven communities in a cross-sectional survey conducted in 2018. Participants underwent several examinations, including assessments of anthropometric parameters, blood pressure, glucose, lipid profiles, UA, total testosterone (TT), estradiol (E2), the follicle-stimulating hormone (FSH), the luteinizing hormone (LH), and dehydroepiandrosterone (DHEA). Results: Among men and compared with individuals in the first quartile, participants in the fourth quartile of TT and FSH had odds of hyperuricemia that were significantly decreased by so much as 48 and 34%, respectively (both P < 0.05). However, participants in the fourth quartile of DHEA had 79% increased odds of hyperuricemia (P < 0.05). Among postmenopausal women, participants in the fourth quartile of DHEA, TT, and LH had odds of hyperuricemia that were significantly increased by 155, 99, and 76%, respectively (all P < 0.05). These associations were adjusted for potential confounding factors. Conclusions: Sex differences were found in the associations between gonadal hormones and UA levels in diabetic men and postmenopausal women, which should be monitored to prevent hyperuricemia when sex hormone treatment, especially DHEA, is administered. Further studies are needed.

Abstract
CONTEXT Despite sex differences in chronic kidney disease (CKD) onset and progression, it is unclear whether endogenous sex hormones are associated with kidney function in persons without CKD. DESIGN AND METHODS We conducted a secondary analysis of the Diabetes Prevention Program (DPP) and its follow-up observational study, the DPP Outcomes Study, over 11 years. Participants included overweight and glucose-intolerant men (n = 889) and pre- and postmenopausal women (n = 1281) not using exogenous sex hormones and whose urine albumin-to-creatinine ratio (ACR) was <30 mg/g and normal estimated glomerular filtration ratio (eGFR) was ≥60 mL/min/1.73 m2 at randomization. We examined the association between sex hormone levels and incidence of low eGFR and/or ACR ≥30 mg/g on at least one measurement. RESULTS At randomization, the mean (SD) eGFR was 94 (15) mL/min/1.73 m2; the median ACR (interquartile range) was 4.5 (3.3 to 7.6) mg/g. During follow-up, 187 men (24.6%) and 263 women (24.2%) had incident albuminuria and 136 men (17.9%) and 123 women (11.3%) had incident low eGFR. Among men, higher baseline sex hormone-binding globulin (SHBG) level was associated with reduced low eGFR risk (hazard ratio per SD, 0.80; 95% CI, 0.57 to 0.90) in adjusted analyses. No significant associations were observed among women. There were significant interactions between sex steroid levels and low eGFR by randomization arm. CONCLUSION Sex steroids were not associated with development of low eGFR or albuminuria. Among men, higher SHBG level was associated with reduced risk of low eGFR on at least one measurement.

Abstract
BACKGROUND Although accumulating evidence shows that aging hormones are involved in glucose metabolism, effects of glycemic control on serum IGF-I and DHEAS levels are still unclear. OBJECTIVE AND METHODS To investigate the effects of glycemic control on these hormone levels, we conducted a 1-month longitudinal study of 49 Japanese patients with Type 2 diabetes mellitus. We measured serum levels of IGF-I and DHEA-S before and after 1-month glycemic control and analyzed the association of changes in IGF-I and DHEA-S with glycated hemoglobin (HbA1c). RESULTS HbA1c was decreased at 1 month with mean changes of -1.2% (p<0.001). Serum IGF-I was increased with mean changes of 11 ng/ml (p<0.05), while serum DHEA-S was decreased with mean changes of -19 μg/dl (p<0.05). Multiple regression analysis showed that changes in DHEA-S were inversely associated with changes in fasting plasma glucose (β=-0.36, p=0.027) and HbA1c (β=-0.33, p=0.028), while changes in IGF-I were not. CONCLUSION The present longitudinal study showed that intensive glycemic control for 1 month increased serum IGF-I level and decreased serum DHEA-S level in Japanese patients with poorly controlled Type 2 diabetes. Further studies are needed to clarify the hormonal changes in IGF-I and DHEA-S after intensive glycemic control would affect diabetic complications.

Abstract
We investigated the relationship between serum dehydroepiandrosterone-sulfate (DHEA-S) and insulin-like growth factor-I (IGF-I) to various parameters for atherosclerosis in type 2 diabetes. The levels of DHEA-S and IGF-I are known to decrease with aging and thereby might be associated with an increased risk of cardiovascular disease. One hundred forty-eight men and 106 postmenopausal women with type 2 diabetes were assessed in a cross-sectional study. Serum DHEA-S and IGF-I concentrations were measured and brachial-ankle pulse wave velocity (baPWV) and ultrasonographically-evaluated intima-media thickness (IMT) were assessed. Although simple regression analysis showed that log(DHEA-S) and IGF-I in men and log(DHEA-S) in women were significantly and inversely correlated with baPWV and IMT, only log(DHEA-S) in women was still significantly and inversely correlated with these atherosclerotic parameters after multiple regression analysis was adjusted for age, duration of diabetes, BMI, HbA(1C), systolic blood pressure, LDL-Cholesterol (C), serum creatinine, and smoking (Brinkman index). Serum DHEA-S level seemed to be associated with atherosclerosis in diabetic postmenopausal women independent of age, body stature, diabetic status, and other atherosclerotic risk factors, and might be a useful addition to other parameters for assessing the risk of atherosclerosis in this population.

The aim of the present study was to examine the relationships between bone mass or bone resorption evaluated by urinary cross-linked N-telopeptides of type I collagen (NTx) concentration and known and potential contributors to bone mass or bone resorption such as sex hormones, age, duration of diabetes, glycemic control (hemoglobin A(1c) [HbA(1c)]), body mass index (BMI), severity of diabetic complications, smoking status, and current treatment of diabetes in postmenopausal women with type 2 diabetes mellitus (n = 196). In addition, the relationship of bone mass to pulse wave velocity, which is an earlier indicator of cardiovascular disease, was investigated in a subgroup of patients (n = 120). Bone mass was evaluated by the quantitative ultrasound method. A higher stiffness index indicates higher bone mass. Inverse correlations were found between the stiffness index and age (r = -0.374, P < .0001) and between the stiffness index and log (urinary albumin excretion) (r = -0.170, P = .0398), and a positive correlation was found between the stiffness index and serum dehydroepiandrosterone sulfate (DHEA-S) concentration (r = 0.201, P = .0136). No significant correlations were found between the stiffness index and duration of diabetes, HbA(1c), BMI, or serum estradiol concentration. No significant correlations were found between urinary NTx concentration and age, duration of diabetes, HbA(1c), BMI, serum estradiol concentration, or serum DHEA-S concentration. The stiffness index correlated inversely with urinary NTx concentration (r = -0.262, P = .0002). No significant correlation was found between the stiffness index and pulse wave velocity (r = -0.165, P = .0714). Multiple regression analysis demonstrated that serum DHEA-S concentration was an independent determinant of the stiffness index (beta = .207, P = .0428). In conclusion, serum DHEA-S concentration correlated positively with bone mass, whereas glycemic control, BMI, or duration of diabetes did not correlate with bone mass or urinary NTx concentration in postmenopausal women with type 2 diabetes mellitus.

Abstract
The aim of this study was to evaluate relationships between serum estradiol concentration and carotid atherosclerosis in addition to major cardiovascular risk factors in men with type 2 diabetes mellitus because previous reports concerning the role of estrogen on atherosclerosis in men are conflicting. Serum estradiol concentrations were measured in 305 consecutive men with type 2 diabetes mellitus. Relationships were evaluated between serum estradiol concentration and carotid atherosclerosis, as determined by ultrasonographically evaluated intima-media thickness (IMT) and plaque score, in a subgroup of 144 diabetic patients, as well as major cardiovascular risk factors, including age, blood pressure, and lipid concentrations. An inverse correlation was found between serum estradiol concentration and IMT (r = -0.174, P = .0369), but no correlation was found between serum estradiol concentration and plaque score. Patients with serum estradiol concentrations in the lowest tertile displayed significantly higher IMT compared with patients in the highest tertile (P = .0083). Serum estradiol concentration was not a determinant of IMT (beta = -.121, P = .1396) in the multiple regression analysis. An inverse correlation was found between serum estradiol concentration and triglyceride concentration (r = -0.136, P = .0186). In conclusion, serum estradiol concentration is inversely associated with carotid atherosclerosis as determined by ultrasonographically evaluated IMT in men with type 2 diabetes mellitus.

Abstract
The aim of the present study was to evaluate relationships between serum endogenous androgens and urinary concentration of cross-linked N-telopeptides of type I collagen (NTx), a bone resorption marker, in men with type 2 diabetes mellitus because low androgen concentrations are associated with both osteoporosis and cardiovascular disease. Relationships between serum free testosterone and urinary NTx concentrations were investigated in 246 consecutive men with type 2 diabetes mellitus. In addition, relationships between urinary NTx concentration and other variables including age, duration of diabetes, blood pressure, serum lipid concentration, hemoglobin A(1c), and body mass index were evaluated. Urinary NTx concentrations were 27.8 (26.4-29.3) nmol of bone collagen equivalent per millimole of creatinine, correlating inversely with serum free testosterone (r = -0.263, P < .0001). Multiple regression analysis identified serum free testosterone (beta = -.292, P < .0001), hemoglobin A(1c) (beta = .144, P = .0404), and smoking status (beta = .143, P = .0402) as independent determinants of urinary NTx. In conclusion, serum free testosterone concentration correlated inversely with urinary NTx concentration, which may partly account for an observed link between osteoporosis and cardiovascular disease in men with type 2 diabetes mellitus.

Abstract
AIMS Metabolic syndrome is characterized by its association with certain cardiovascular disease risk factors. The aim of this study was to investigate the relationships between metabolic syndrome and markers of subclinical atherosclerosis, serum adiponectin and endogenous androgen concentrations in Japanese men with Type 2 diabetes. METHODS Using the 2005 International Diabetes Federation (IDF) definition, we assessed the prevalence of the metabolic syndrome in 424 consecutive men with Type 2 diabetes aged 40-75 years in a cross-sectional study. We compared characteristics including ultrasonographic carotid atherosclerosis markers, pulse-wave velocity (PWV), and serum adiponectin, free testosterone, and dehydroepiandrosterone sulphate (DHEA-S) concentrations in diabetic patients with and without the metabolic syndrome. RESULTS The prevalence of the metabolic syndrome in Japanese men with Type 2 diabetes was 46.9%. Men with the metabolic syndrome had higher urinary albumin excretion rate than those without. Carotid intima-media thickness (0.97 +/- 0.26 vs. 0.91 +/- 0.18 mm), plaque score [3.3 (1.5-8.1) vs. 3.8 (1.3-6.2)], PWV (1818 +/- 331 vs. 1749 +/- 331 cm/s) and ankle-brachial index (1.10 +/- 0.14 vs. 1.08 +/- 0.16) did not differ significantly between patients with and without the metabolic syndrome. Similarly, serum adiponectin [3.70 (2.06-6.09) vs. 4.65 (3.09-7.02) microg/ml], free testosterone (36.4 +/- 10.7 vs. 34.7 +/- 11.1 pmol/l), and DHEA-S concentrations (3.29 +/- 1.83 vs. 3.17 +/- 1.63 micromol/l) did not differ significantly between groups, CONCLUSIONS The metabolic syndrome, as defined by the IDF, is not significantly associated with subclinical atherosclerosis markers, serum adiponectin, or endogenous androgen concentrations in Japanese men with Type 2 diabetes.

Abstract
We recently found that serum dehydroepiandrosterone sulfate (DHEA-S) concentration correlated inversely with the degree of urinary albumin excretion in a cross-sectional study. We therefore performed an observational study to investigate the relationship between serum DHEA-S concentrations and changes in urinary albumin excretion in male patients with type 2 diabetes to answer the question as to whether DHEA is a causal rather than simply coincidental intermediate linking urinary albumin excretion to cardiovascular disease (CVD). The relationship between serum DHEA-S concentration and changes in urinary albumin excretion was investigated in 207 consecutive male patients with type 2 diabetes. Baseline serum DHEA-S concentration and urinary albumin excretion were measured in 2003. After 12 months, urinary albumin excretion was measured and any changes in urinary albumin excretion were calculated. Patients were divided into tertiles according to DHEA-S concentration. Greater changes in urinary albumin excretion were seen in patients with low DHEA-S concentration (29.6+/-7.6mg/g creatinine) than in patients with high DHEA-S concentration (5.1+/-3.6mg/g creatinine, P=0.0091). An inverse correlation was observed between serum DHEA-S concentration and changes in urinary albumin excretion (r=-0.193, P=0.0052). Multiple regression analysis demonstrated that HbA1c (beta=0.241, P=0.0009), and serum DHEA-S concentration (beta=-0.195, P=0.0054) were independent determinants of changes in urinary albumin excretion. In conclusion, serum DHEA-S concentration was inversely correlated with changes in urinary albumin excretion, which may indicate causality in the increased CVD mortality in male patients with type 2 diabetes and low DHEA-S concentration.
