Introduction: The aim of our study was to assess the values of total cholesterol, HDL-C, LDL-C and triglycerides before and after treatment with metformin in patients with polycystic ovary syndrome (PCOS) and normal lean.Material and methods: 32 patients received metformin 1500 mg/day in three divided doses. Lipids measurements were performed to each patient with PCOS twice: before and after 6 months of treatment with metformin.Res...

: Hyperinsulinemia is one of biochemical features of polycystic ovary syndrome (PCOS). Metformin is a common drug used in PCOS. Recent studies have shown that metformin has impact on clinical and biochemical parameters in PCOS patients. The aim of our study was to assess retrospectively the influence of metformin on total testosterone, sex hormone binding globulin (SHBG) and free androgen index (FAI) in women with PCOS in polish cohort. A total of 54 patients with PCOS and irr...

Introduction: The aim of our study was to assess the morning and evening cortisol plasma levels in women with polycystic ovary syndrome (PCOS).Material and method: 95 patients gave their informed consent to participate in the study and were divided into two groups. Group A consisted of 40 PCOS patients and group B consisted of 55 women without features of PCOS. Between day 5 and 8 of the menstrual cycle, morning (0700 h), fasting blood samples were taken...

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...

Aim: Aim of our study was to compare: the baseline and metoclopramide induced prolactin plasma level between PCOS women with FAI <5 phenotype (group A)(FAI, total testosterone divided by sex hormone biding globulin, whole multiply by 100) and PCOS women with FAI>5 phenotype (group B).Patients and methods: The study population consisted of 354 lean women with PCOS. In all the patients the prolactin level at 02:00 h, 08:00 h and during the metoclop...

Aim: Evaluation of pressure pain threshold and β-endorphin plasma level in lean women with polycystic ovary syndrome (PCOS) and healthy controls. The associations between β- endorphins and pressure pain threshold were also investigated.Materials and methods: In 48 lean women with polycystic ovary syndrome and 38 lean women without this disorder plasma β-endorphins and pressure pain thresholds were measured.Results: T...

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...

Introduction: Polycystic ovary syndrome (PCOS) is one of the most common causes of anovulatory and infertility. According to the widespread data it affects 3–10% of women in the procreative age. Although many research have been done, it is still unclear which of mechanisms are responsible for the development of PCOS. The most up-to-date scientific trial indicates that the evolution of PCOS is related to the activity of the endogenous opioid system but precise mechanism is...

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...

Aim: To assess lipid levels in patients with PCOS and normal body weight.Materials and methods: 139 patients admitted to the Gynaecologic Endocrinology Clinic of the Jagiellonian University’s Collegium Medicum agreed to take part in this research, and PCOS, according to the Rotterdam criteria, was found in 96 of them. The control group consisted of 43 patients with FAI <5. All of the 96 patients had a normal (BMI <25) body weight. This index...
