The aim was to assess associations among metabolic abnormalities in polycystic ovary syndrome (PCOS) and NAFLD.Materials and methods: In 184 women with PCOS and 125 healthy premenopausal volunteers sex steroids, lipids, glucose, insulin, aminotranspherases, CRP, free androgen index (FAI), HOMA and E2:testosterone were calculated. Hepatic steatosis was determined by ultrasound. The analysis of multivariate (logistic regression) due to the prese...

The aim of this study was to determine whether polymorphisms (TaqI, ApaI, BsmI, and FokI) of the vitamin D receptor (VDR) show a correlation with the serum level of the testosterone in the aging men population.A group of 224 men aged 65–90 years, randomly selected from the group of 5695 persons included in the PolSenior project was studied. We established genotype prevalence of the VDR gene polymorphisms (TaqI, rs10735810; ApaI, rs1544410; BsmI, rs7...

Recently, low serum adiponectin levels is created as a new risk factor for cardiovascular diseases in climacteric women. Our previous study shows that smoking, serum testosterone levels, blood pressure and BMI have the influence on serum adiponectin levels. Endocannabinoid system plays a role in regulation of food intake and fat accumulation, as well as lipid and carbohydrate metabolism. Menopause transition is related to metabolic disorders (e.g. obesity) and cause the increa...

Introduction: Polycystic ovary syndrome (PCOS) is associated with metabolic disorders such as insulin resistance, hyperinsulinemia, dyslipidemia and central obesity which increase the risk of cardiovascular diseases (CVD). Lipid accumulation product (LAP) and waist circumference to height ratio (WHtR) are novel CVD risk predictors based on the assessment of waist circumference, height and serum triglycerides. The aim of our study was to evaluate the LAP and WHtR associations w...

Irisin (Ir), a recently identified adipomyokine, cleaved and secreted to the circulation from the FNDC5 protein in response to physical activity and some environmental conditions has been postulated to induces the differentiation of a subset of white adipocytes into brown fat and mediates the beneficial effects of exercise on metabolic homeostasis. Polycystic ovary syndrome (PCOS) – one of the most frequent endocrinopathies affecting women of child-bearing age is associat...

Brown adipose tissue metabolism is of remarkable pathophysiological interest, because it could be a target for future therapies for obesity and metabolic syndrome. Irisin (Ir), recently identified novel adipomyokine is essential in a white-to-brown fatty tissue transdifferentiation, and mediates some of the positive influences on metabolic disorders through increase of energy expenditure. The exact regulation of Ir secretion and action is unknown but significant positive assoc...

Aggravation of the symptoms of Alzheimer’s disease may also underlie the functioning of receptors associated with calcium and vitamin D. Therefore, it seems reasonable to study the correlation of polymorphisms of vitamin D receptor (VDR) and calcium receptor (CASR) with symptoms of AD. Alzheimer’s disease, vitamin D deficiency and osteoporosis often coexist in the patient. Research suggests that vitamin D deficiency is much more frequent in the patients with AD. Expr...

Polycystic ovary syndrome (PCOS) is a common endocrine abnormality connected not only with reproductive problems but also with impaired energy homeostasis leading to metabolic disorders including metabolic syndrome. Irisin (Ir), recently identified novel myokine, has been proposed to mediate some of the positive influence on metabolic disorders. The aim of our study was to search the relationship between Ir plasma concentration in PCOS in the context of metabolic disturbances....

Objective: Genetic factors play a major role in obesity. Numerous studies have confirmed associations of the SNP rs9930506 of FTO gene with increased BMI, hip circumference and total body weight. The metabolic consequences of obesity depend, to a large degree, on body fat distribution.MONW individuals (metabolically obese normal-weight), despite their normal BMI, are characterized by visceral obesity and display metabolic properties that may pre...

Some individuals with normal weight but probably visceral fat excess, called Metabolically Obese Normal-Weight (MONW), have disturbances typical for metabolic syndrome. We analyzed relationships between body fat distribution (estimated by DXA) and insulin resistance, serum inflammatory markers levels (CRP, IL-6, IL-18) and polymorphisms of IL-6 promoter and PPARγ in healthy, non-obese Polish subjects: 232 women (age 31.4±5.5; BMI 21.5±2.5) and 199 men (age 30.3&...
