The presence of nonalcoholic fatty liver disease (NAFLD) is a strong risk predictor for type 2 diabetes (T2D). A reduction in sex hormone-binding globulin (SHBG) is associated with NAFLD. Low SHBG is also associated with insulin resistance (IR). However, very limited data are available for the association of SHBG and IR in patients with NAFLD. The study aims to clarify the association between SHBG and IR in patients with NAFLD. In this cross-sectional study, 334 men with NAFLD were recruited. SHBG, total testosterone, free testosterone, total cholesterol, triglyceride, insulin, and glucose concentrations were measured...

Previous reports have shown that exercise improves serum leptin and adiponectin abnormalities in overweight and obese individuals; however, results to date are controversial. Here we performed a systematic review and meta-analysis of the available randomized controlled trials (RCTs) of the possible beneficial action of exercise on serum leptin and adiponectin levels in overweight and obese individuals. We searched PubMed, EMbase, The Cochrane Library, and the Clinicaltrial.gov databases for relevant studies published between January 1980 and September 2015...

Previous studies reported a higher prevalence of venous-thromboembolic events among patients with Cushing disease (CD) compared to those with ACTH-independent Cushing syndrome (CS) from adrenal sources. The objective of the current study was to evaluate the coagulation profile of patients with CS from different etiologies. A prospective observational study was conducted at a clinical research center. The study included adult patients admitted for evaluation of suspected CS (n=85), that were divided into 3 groups: CD (n=22), ACTH-independent CS from an adrenal tumor/hyperplasia (adrenal CS, n=21), and a control group consisting of subjects with negative screening for CS (rule-out CS, n=42)...

Long-standing exposure to endogenous cortisol excess is associated with high cardiovascular risk. The aim of our study was to investigate arterial stiffness, which has been recognized as an independent predictor of adverse cardiovascular outcome, in a group of patients with Cushing's syndrome. Twenty-four patients with Cushing's syndrome (3 males, mean age 49±13 years; 20 pituitary-dependent Cushing's disease and 4 adrenal adenoma) underwent 24-h ambulatory blood pressure monitoring (ABPM) and evaluation of cardiovascular risk factors...

The physiological function of DPP-4 in proteolytic inactivation of incretins has been well established, however, there is limited information on the expression and the significance of DPP-4 in white adipose tissue with regard to obesity. The objective of the work was to reveal the expression and regulation of DPP-4 in adipocytes and compare the expression and activity of DPP-4 in white adipose tissue and several other organs such as the liver, muscle and kidney. We also investigated the gene expression levels of DPP-4 substrate chemokines, and their receptors in white adipose tissue...

Catecholamine excess from pheochromocytoma results in cardiovascular symptoms such as arterial hypertension and tachycardia and induces metabolic alterations including glucose intolerance and increase in resting metabolic rate. The objective of our study was to investigate the effect of surgical cure of pheochromocytoma on body-mass-index and the correlation of body-mass-index changes to preoperative endocrine parameters. Pheochromocytoma patients from the Munich ENSAT Registry were matched (1:2) for age and gender to patients from the German Conn's Registry, who had undergone surgery for aldosterone-producing-adenomas...

Graves' orbitopathy (GO) is characterized by orbital T cell infiltration. We evaluated the regulatory T (Treg) cell fractions induced with IGF-1 in Graves' disease (GD) with and without GO. Peripheral blood mononuclear cells (PBMCs) were obtained from 13 patients with GD without eye manifestations; 10 patients with active GO; and 12 patients with nodular goiter (NG). All the patients from GD, GO, and NG were subclinical hyperthyroid. We analyzed the expression of Treg cell markers (CD4, CD25, CD127(-), Foxp3) on T cells and their ability to respond to IGF-1 stimulation...

Muscle wasting is one of the main contributors to the worse outcomes in sepsis. Whether estrogen could alleviate muscle wasting induced by sepsis remains unclear. This study was designed to test the effect of estrogen on muscle wasting and its relationship with central alteration in sepsis. Thirty Sprague-Dawley rats were divided into 3 groups: control group, sepsis group, and estrogen treated sepsis group. Animals were intraperitoneally injected with lipopolysaccharide (10 mg/kg) or saline, followed by subcutaneous injection of 17β-estradiol (1 mg/kg) or saline...

Despite the efficacy and safety, antithyroid drug (ATD) therapy for Graves' disease (GD) is associated with a high risk of relapse, especially within the first year. The inability to predict whether and when relapse may occur is a major problem for ATD therapy. This study was aimed to investigate potential predicative factors for GD patients after ATD withdrawal. Consecutive patients newly diagnosed with GD and treated with ATD [methimazole (MMI)] were enrolled in this study. Univariate and multivariate Cox proportional hazard analyses were used for the analysis of predicative parameters for GD relapse after MMI withdrawal...

In the normal human adrenal gland, serotonin (5-HT) stimulates aldosterone secretion through the 5-HT4 receptor (5-HT4R). However, the physiological role of the serotonergic control of adrenocortical function is not known. In the present study, we have investigated the ability of l-Lysine, which has been shown to act as a 5-HT4 receptor antagonist, to counteract in vitro and in vivo the stimulatory effect of 5-HT4R agonists on aldosterone production. l-Lysine was found to inhibit aldosterone production induced by 5-HT and the 5-HT4R agonists BIMU8 from cultured human adrenocortical cells...

Epicardial adipose tissue (EAT) plays a role in cardiac physiology and may contribute to the development of coronary artery disease. Our objective was to determine whether there was a significant difference in gene expression in EAT compared to subcutaneous adipose tissue (SAT) and to identify potential relationships. MEDLINE and EMBASE were searched using the key terms "Epicardial Adipose Tissue" or "Epicardial Fat" in combination with "RNA", "mRNA", or "gene". The entry criteria were studies that presented primary data including expression levels of mRNA in human EAT compared with SAT and an expression of variance (SD)...

Neuroendocrine tumours (NET) are rare neoplasms, but the incidence is permanently increasing. Most of the NETs are slow proliferating and clinically silent, and for that reason, they are often diagnosed at a stage with advanced disease. The complexity and diversity of the NET-biology require the treatment of patients in specialised centres to guarantee a qualified, multidisciplinary treatment planning. At our institution, we developed an interdisciplinary model for the assessment and treatment of NET. The aim was to adapt the guidelines to the clinical practice, exchange of current knowledge, and a tailored approach to the individual patient...

Irisin (Ir) deficiency may be a contributing factor in metabolic disease. This study aimed to investigate the effect of supraphysiological doses of recombinant human growth hormone (rhGH) on Ir plasma concentration in relation to metabolic disorders, including obesity and other components of metabolic syndrome. We studied 36 girls with Turner syndrome (mean age 8.2 years) treated with rhGH (0.05 mg/kg/day). Anthropometric data and fasting blood levels [e. g., Ir, insulin, glucose, glycated hemoglobin (HbA1c), IGF-1, IGFBP-3, cholesterol, insulin resistance (HOMA-IR), and β-cell function (HOMA-β)] were analyzed prior to and following rhGH therapy [mean (SD) follow-up of 1...

Familial hypocalciuric hypercalcemia (FHH) belongs to the disorders of a disturbed calcium homeostasis. Genetically, the disorder is inherited in an autosomal-dominant trait and represents an inactivating mutation of the calcium sensing receptor (CaSR) gene. We identified a Franconian kindred in which 6 individuals could be tested by molecular genetic means. In 5 individuals of 3 generations, the mutation could be classified as c.1697_1698delTG. This novel germline mutation creates a premature stop codon leading to a loss of 510 amino acids of the protein...

Whereas several in vitro and in vivo studies have described the role of lysosomal associated membrane protein 2 (LAMP2) in lipid homeostasis, there is no study addressing LAMP2 serum concentration and its association with lipid profiles in the context of coronary artery disease (CAD). We aimed to determine the LAMP2 serum concentration and its association with serum lipid profiles as well as the gene expression of LAMP2 in peripheral blood mononuclear cells (PBMCs) of CAD patients and control group. Circulating levels of LAMP2 were quantified by enzyme-linked immunosorbent assay (ELISA) in CAD patients (n=85) and control group (n=65) and correlation to lipid parameters was assessed...

Lower thyroid functional status within the euthyroid range may confer increased atherosclerosis susceptibility, as evidenced by increased intima media thickness and coronary artery calcification. Associations of lower thyroid functional status with pro-atherogenic (inflammatory) biomarkers may also extend into the euthyroid range. Here we established relationships of plasma tumor necrosis factor-α (TNF-α) with thyroid stimulating hormone (TSH) and free thyroxine (free T4) in euthyroid subjects with and without Type 2 diabetes mellitus (T2DM)...

Polycystic ovary syndrome (PCOS) is a heterogeneous, multi-causal, and genetically complex disorder, which is related to the failure in endocrine glands. Adiponectin has been reported to be low in PCOS, even in the absence of adiposity. Quercetin reduces serum glucose, insulin, triglycerides, and cholesterol levels and increases the expression and secretion of adiponectin. The aim of this study was to determine the effect of quercetin on the adiponectin-mediated insulin sensitivity in PCOS patients. Eighty-four women with PCOS were selected and randomly assigned to 2 groups of treatment and control...

The present study was designed to evaluate the effects of metformin on metabolic and endocrine parameters in patients with polycystic ovary syndrome (PCOS). The study included 40 patients with PCOS. Patients were divided into 2 groups based on whether they will receive metformin (500 mg 3 times a day, n=20) or placebo (n=20) for 3 consecutive months. Serum concentrations of fasting blood glucose, insulin, HOMA-IR, INSL-3, visfatin, FSH, and LH were measured at baseline and after 3 months of therapy. The key endocrine and metabolic parameters significantly changed after metformin treatment...
