Objective: Intriguing studies suggest that osteocalcin (OC) and its carboxylated (Gla)/uncarboxylated form are involved in the regulation of insulin secretion and action. Additionally, advanced glycated end products (AGEs), directly regulate the secretion of these osteoblast derived molecules. In PCOS among the pathophysiological aberrations, deregulation of insulin secretion and action as well as elevated AGEs levels have been demonstrated. In this study, we evaluated the ser...

Background: Chronic anovulation constitutes one of the cardinal features of Polycystic Ovary Syndrome (PCOS) and Anti-Müllerian hormone (AMH), a granulosa cell product, is a well documented marker of anovulation. Recent data have shown that oxidative stress is involved in the pathophysiology of anovulation. A marker of oxidative stress, Advanced Glycosylated End products (AGEs), is implicated to the pathogenesis of the syndrome and have been localized with high intensity ...

Background: Conflicting results regarding adiponectin levels in women with polycystic ovary syndrome (PCOS) have been reported. To evaluate adiponectin levels in PCOS, a systematic review of all studies comparing adiponectin levels in women with PCOS to healthy controls and a meta-analysis of those involving women with similar Body Mass Index (BMI) were performed. Influence of possible effect modifiers, such as insulin resistance (IR) and testosterone, was investigated. Influe...

In insulin resistant, young women with PCOS elevated serum AGEs and their receptor RAGE have been reported. The present study (approved by the local ethical committee) was undertaken to determine whether increased levels of serum AGEs in PCOS is a distinct finding compared with age- and BMI-matched women, presenting the isolated components of the syndrome and whether serum AGE levels were different among PCOS phenotypes. A total of 193 lean non-insulin resistant women were stu...

Background: Polycystic ovary syndrome (PCOS) is associated with obesity and insulin resistance, two major contributors to cardiovascular risk. Even in the absence of detectable insulin resistance, lean, non-diabetic PCOS women demonstrate increased circulating levels of advanced glycated end products (AGEs), known proatherogenic molecules. This adverse cardiovascular risk profile should be considered in the syndrome’s management.Objective: To invest...
