BACKGROUND: Polycystic ovary syndrome (PCOS) is a common female endocrine condition of unclear etiology characterized by hyperandrogenism, oligo/amenorrhoea, and polycystic ovarian morphology. PCOS is often complicated by infertility, overweight/obesity, insulin resistance, and low-grade inflammation. The gut microbiome is known to contribute to several of these conditions. Recently, an association between stool and saliva microbiome community profiles was shown, making saliva a possible convenient, non-invasive sample type for detecting gut microbiome changes in systemic disease...

BACKGROUND: Polycystic Ovary Syndrome (PCOS) is a prevalent endocrine/metabolic disorder characterized by hyperandrogenemia and in most cases, by hyperinsulinemia in addition to obesity. Besides ovarian dysfunction, endometrial physiology is also disrupted since this tissue is highly dependent on the action of steroids; in case of conception cycles, high percentage of abortion is observed. Because of the endocrine/metabolic alterations, PCOS-women present high probability to develop hyperplasia and endometrial cancer, where an imbalance of cell proliferation/apoptosis processes is detected...

BACKGROUND: Polycystic Ovary Syndrome (PCOS) is a complex heterogeneous disorder and the most common endocrinopathy amongst women of reproductive age. It is characterized by androgen excess, chronic anovulation and an altered cardiometabolic profile. PCOS is linked to impaired adipose tissue (AT) physiology and women with this disorder present with greater risk for insulin resistance (IR), hyperinsulinemia, central adiposity, nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) than matched for age and body mass index (BMI) women without PCOS...

Accumulating evidence indicates that leptin acts as an important mediator in energy homeostasis and reproduction. Since dysfunction of reproduction and metabolism are major characteristics of polycystic ovarian syndrome (PCOS), the role of leptin in pathogenesis of PCOS needs further research. Many studies have shown that central leptin resistance existed in obesity rats through leptin intracerebroventricular (icv) injection; however, central leptin resistance in PCOS rats has not been reported. This study aimed to investigate whether there was a state of central leptin resistance in PCOS rats, as well as explore the possible association of hypothalamic inflammation with central leptin resistance...

BACKGROUND: Polycystic ovary syndrome (PCOS) is considered to be a multifactorial disorder resulting from the interaction of several predisposing and protective genetic variants. PCOS is associated with low-grade chronic inflammation. Elevated levels of inflammatory markers including intercellular adhesion molecule-1 (ICAM-1) are demonstrated in women with PCOS. Recent evidence indicates a significant linkage between a locus on chromosome 19p13 and multifactorial diseases that have an inflammatory component...

Hirsutism affects 5-25% women, and the condition is most often caused by polycystic ovary syndrome (PCOS). The initial evaluation of hirsute patients should include a thorough medical history, clinical evaluation, and standardized blood samples to diagnose the 5% hirsute patients with rare endocrine disorders. The majority of these examinations can be performed by the patient's general practitioner. PCOS is a diagnosis of exclusion and is a multiorgan disease affecting most endocrine organs including ovaries, adrenals, pituitary, fat cells, and endocrine pancreas...

CONTEXT: Adropin is a peptide hormone implicated in the regulation of insulin sensitivity and energy homeostasis. Polycystic ovary syndrome (PCOS) is a metabolic and reproductive disease associated with insulin resistance. It has been demonstrated that various inflammatory markers increased in PCOS including TNF-α. TNF-α regulates the secretion of certain peptides which play a crucial role in glucose and lipid homeostasis. There is also some evidence of a link between TNF-α and adropin...

The aims of the current study were to examine the effects of temporal changes in oxidative stress (OS) and low-grade inflammation in letrozole-treated rats and to correlate these changes with the development of polycystic ovary syndrome (PCOS)-like features. Rats were treated with letrozole for 7, 15 and 21 days to induce PCOS. On day 7 of the treatment, a significant increase in serum testosterone and high sensitive C-reactive protein (hsCRP), the low-grade inflammatory marker, was found in the letrozole treated rats compared to control rats...

Polycystic ovary syndrome (PCOS), a heterogeneous syndrome of reproductive and metabolic alterations, is associated with increased long-term risk of cardiovascular complications. This phenomenon has been linked to an increase in oxidative stress and inflammatory markers. Advanced glycation end products (AGEs) are pro-inflammatory molecules that trigger a state of intracellular oxidative stress and inflammation after binding to their cell membrane receptors RAGE. The activation of the AGE-RAGE axis has been well known to play a role in atherosclerosis in both men and women...
