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...

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...

Interindividual variations in tissue sensitivity to glucocorticoids (GC) have been partly attributed to polymorphisms in the glucocorticoid receptor (GR) gene. The aim of this study was to investigate whether BclI variant of the GR gene may contribute to metabolic abnormalities frequently present in patients with adrenal incidentaloma (AI). Biochemical tests and hormonal evaluation were performed in 106 consecutive women with AI. Non-diabetic patients underwent an ora...

Neuroendocrine tumors encompass a heterogeneous group of tumors arising from the diffuse neuroendocrine system. The incidence of NETs rises with age, with the peak after 65 years. However, all NETs observed in adults may be diagnosed in children too. There are a very few studies addressing NETs in young patients. This study summarizes clinical, histopatological and genetic characteristics of young patients with NETs. This is a retrospective study describing clinical, histopath...

Introduction and aims: Autoimmune thyroiditis represent a state predisposed for the development of hypothyroidism. It is known that subclinical and overt hypothyroidism are important risk factors associated with the development and progression of heart failure. These effects are due to the changes in the structure and function of the cardiac muscle, as well as the overall cardiac mechanics. The aim of our study was to examine the influence of autoimmune thyroiditis (Hashimoto ...

To investigate the prevalence of SH and osteoporosis in female patients with unilateral AIs (UAIs) and bilateral AIs (BAIs).We enrolled 106 female patients, 68 (64.2%) with UAIs and 47 (35.8%) with BAIs. SH was diagnosed in the presence of serum cortisol levels after 2-day low-dose dexamethasone suppression test (LDDST) >50 nmol/l with at least one of the following parameter (midnight serum cortisol >208 nmol/L, 24-h urinary free cortisol >24...

PNETs represent the leading cause of mortality in MEN1 patients. Yet, their characteristics, behaviour, and therefore management, are still uncertain.The aim of this study was to describe the main clinical characteristics of NETs in MEN1, and to compare them with sporadic NETs.We investigated 164 patients with PNETs retrospectively, treated in one centre from 2004–2016. We identified 15 (9.1%) patients with MEN1. All patients ...

Activation of hypothalamo-pituitary-adrenal (HPA) axis is a common feature of endocrine responses to stress, with cortisol secretion as an end product of this activation. Acute rise in cortisol level during stress is of utmost importance for metabolic adjustments, immune system adaptations, cardiovascular responses and muscle tissue remodeling. But since chronic hypercortisolism has many deleterious effects, scientific interest has started focusing around different biological ...

Introduction: Insulin resistance (IR) is a well recognised feature in women with polycystic ovary syndrome (PCOS). The aim of this study was to analyse IR indices obtained from oral glucose tolerance test (OGTT), in different PCOS phenotypes.Methods: We evaluated 240 PCOS women (PCOS: 24.86±5.97 kg/m2; 25.25±4.98 years) diagnosed using ESHRE/ASRM criteria and 70 BMI-matched healthy women (controls: 26.14±4.86 kg/m2; 3...

Introduction: Although phenotype D is well recognised in clinical studies about PCOS, there is still a debate if this phenotype should be evaluated as part of PCOS spectrum. The aim of this study was to evaluate usual anthropometric characteristics in PCOS phenotypes.Methodology: 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: 25.4...
