It has been more than 70 years since the first adrenal incidentalomas (AI) were described. Most of these tumors are non-secreting, and are found in 4–7% of adult population. Patients with subclinical hypercortisolism (or autonomous cortisol secretion) (SH) are observed in 1–29% of patients with AIs. Evidence suggests that this condition may be associated with higher prevalence of diabetes, obesity, hypertension and osteoporosis.Between 1999 and...

Introduction: Women with polycystic ovary syndrome (PCOS) are at increased risk of developing insulin resistance (IR) and T2DM. In this study, we attempted to detect IR parameters that could be the best predictor T2DM in PCOS comparing to controls.Description of methods/design: In 130 women with PCOS (BMI=29.7±0.66 kg/m2; age: 25.6±0.59 years) and 41 controls (age and BMI matched) (BMI=28.5±1.35 kg/m2; age: 26.5±...

One-hour (1 h) glucose level of the oral glucose tolerance test (OGTT) was proven to be a better predictor of insulin resistance (IR) in nondiabetic population than the two-hour (2 h) postload glucose level. Specifically, the 8.6 mmol/l cut-off was shown to be an early marker of impaired glucose tolerance (IGT). Previous studies have shown that nondiabetic patients with adrenal incidentalomas (AI) have higher IR than healthy control (HC). However, despite the subtle cortisol s...

High prevalence of insulin resistance (IR) has been shown in patients with adrenal incidentalomas (AI) and it has been demonstrated that an increase in IR is related to the adrenal tumor size (ATS). Also, responsive adrenal pathologies are well documented in patients with chronically elevated LH. The aim was to investigate the association between LH and IR and ATS and IR in AI patients. The case-control study was conducted in Clinic for endocrinology, diabetes and metabolic di...

At present there are no unified diagnostic criteria for subclinical hypercortisolism (SH) in patients with adrenal incidentalomas (AI). Recently it has been proposed that an age and gender specific DHEAS ratio (calculated by dividing DHEAS by the lower limit of the respective reference range) has a significant diagnostic value in detection of SH.The aim was to evaluate the value of DHEAS as a diagnostic tool for SH. Retrospectively we evaluated 140 AI pa...

Introduction: Obesity is a risk factor for the development of insulin resistance, type 2 diabetes, cardiovascular diseases and non-alcoholic fatty liver disease. The aim of our study was to examine predictive value of liver enzymes in assessing biomarkers of insulin sensitivity in obese, non-diabetic adults.Methods: 1104 obese, non-diabetic adults were included in the study. Patients were divided into two groups: Group A (BMI 30.0–39.9 kg/m2</s...

Introduction: Women with polycystic ovary syndrome (PCOS) are at increased risk of developing insulin resistance and type 2 diabetes mellitus (T2DM). The aim of this study was to detect insulin resistance parameters that could be the best predictor T2DM in PCOS when compared with healthy women.Methods: This study include 114 PCOS women (BMI: 29.2±0.60 kg/m2; age: 25.3±0.57 years) and 41 controls (age- and BMI-matched) healthy women (...

Introduction: It is well documented that adrenal tumor tissue is responsive to human chorionic gonadotropin (hCG) as well as to luteinizing hormone (LH) with both hormones sharing a similar physiological role and a mutual receptor.Objective: The objective of our study was to assess the adrenal steroid response to acute, exogenous hCG stimulation in patients with adrenal incidenatalomas (AI) and for the first time, in a healthy control group.<p class=...

Introduction: It was showed that low SHBG represent an independent bio-marker of proinflammatory states associated with insulin resistance. Recent studies provide additional evidence that insulin plays no role in decreasing hepatic SHBG production, and that proinflammatory cytokines, contribute indirectly to reducing SHBG expression in liver of obese persons by reducing hepatic HNF-4α. Obesity in men is commonly accompanied by a decline of serum total testosterone and bio...
