Introduction: Luteinizning hormone (LH/hCG) responsiveness has been documented in both normal and pathological adrenal glands, but it is unclear whether chronic exposure to LH could affect adrenal function by increasing LH receptor (LHR) expression.Subjects and methods: We studied 12 postmenopausal women with previously documented adrenal tumor. All patients underwent standard hormonal testing for assessment of tumor functionality. Then hCG test was perf...

Adrenocortical carcinoma (ACC) is rare malignancy associated with poor prognosis. The aim of this study was to present clinical characteristics and survival of patients with ACC and to analyse the effect of prognostic factors on survival.We retrospectively analysed 69 patients (46 female and 23 males) with pathologically confirmed ACC who were treated in our hospital between January 2005 and December 2015. The median age at diagnosis was 51,0 years (rang...

Introduction: Dyslipidaemia is a common metabolic derangement in polycystic ovary syndrome (PCOS) and may be represented with different lipid alterations. The aim of this study was to evaluate lipid profile in different PCOS phenotypes.Methods: We evaluated 365 PCOS women (PCOS: 25.05±6.24 kg/m2; 25.48±5.21 years) diagnosed using ESHRE/ASRM criteria and 125 BMI-matched healthy women (controls: 25.41±5.16 kg/m2; 30.35&...

Introduction: Insulin resistance and obesity are common features of polycystic ovary syndrome (PCOS) and both are independently associated with dysglycaemia. The aim of this study was to determine prevalence of dysglycaemia in obese women with PCOS.Methods: PCOS was diagnosed using ESHRE/ASRM criteria. Obesity was defined as BMI ≥25 kg/m2. We evaluated 100 obese women with PCOS (PCOS group: 28.99±3.05 kg/m2; 27.70±5....

Introduction: Chromogranin A (CgA) is a major representative of the protein family named granins stored predominately in secretory granules of the diffuse neuroendocrine system. Circulating CgA serves as a biomarker of neuroendocrine tumors (NETs), but its increased plasma concentration is present in various cardiovascular, gastrointestinal, renal and inflammatory diseases. Intra-granular and/or extracellular proteolysis of CgA generates a variety of biologically active fragme...

Introduction: Hormonal syndromes are significant cause of morbidity in patients with neuroendocrine tumors (NET), requiring special treatment, rarely completely efficient. Effect on mortality is also presumed. Our aim was to investigate epidemiological characteristics of NET with hormonal production in our group of patients.Patients and methods: We analyzed 822 patients with NET of various primary tumor sites, treated at our department during period of 2...

Introduction: Women with polycystic ovary syndrome (PCOS) have numerous risk factors that lead to higher risk for cardiovascular diseases (CVD) and stroke. Measurement of carotid intima-media thickness (CIMT) is a marker of CVD.Methods: We analyzed 399 women with PCOS diagnosed using ESHRE/ASRM criteria (age: 25.5±5.1 years, BMI: 24.9±6.2 kg/m2), and 82 BMI-matched healthy controls (age 29.2±5.9 years, BMI 25.3±8.6 kg/m<sup...

IntroductionHypogonadism is a potential manifestation of many chronic diseases including cancer, presumably related to their severity. Since novel anti-cancer treatments have significantly increased survival rates of affected patients, issue of hypogonadism becomes more significant, given the importance of issues like quality of life and potential for reproduction. The aim of our study was to analyze gonadal axis function in male patients with neuroendoc...

Introduction: The majority of adrenocortical incidentalomas (AIs) are nonfunctional adenomas. Some of them demonstrate an autonomous cortisol secretion (ACS), a pathologic condition defined as biochemical evidence of hypercortisolism without typical signs or symptoms of Cushing’s syndrome.Subjects and methods: In this cross-sectional study, we evaluated 152 consecutive patients, aged 58.3 years (range, 25-84 years) of whom 105 (69.1%) with unilatera...

Introduction: Multiple endocrine neoplasia type 2 is an autosomal dominant polyglandular cancer syndrome. It arises as a result of a germline mutation of the RET proto-oncogene. The aim of this study was to evaluate the aggressiveness of medullary thyroid carcinoma (MTC) in patients with a proven germline mutation in codon 634 RET proto-oncogene, the occurrence of other associated diseases and survival analysis.Methods: The retrospectiv...
