Background: Glucocorticoids (GCs) have an important modulatory influence on immune system. GCs accomplish their effects on target tissue through binding to the glucocorticoid receptor (GR). Alterations in glucocorticoid signaling due to polymorphisms of the GR gene may have an impact on the pathophysiology of autoimmune disorders.Aims/methods: We examined the presence of BclI, N363S, A3669G and ER22/23EK GR gene variants in patients with autoimmun...

Neuroendocrine lung tumors represent approximately 20% of all lung tumors. They range from low-grade well-differentiated NETs and well-differentiated neuroendocrine carcinomas (typical and atypical carcinoids) to aggressive poorly differentiated small-cell and large-cell neuroendocrine carcinomas. They can develop different clinical syndromes due to ectopic hormone secretion.We analyzed 178 patients with neuroendocrine tumors (age range: 17–79 years...

Pancreatic neuroendocrine tumors (PETs) occurs in approximately 1 per 100 000 people per year and account for only 1–2% of all pancreatic tumors. Most of them are hormonally active, while about 30% secrete no detectable hormons and are discovered due to a tumor mass effect.Material and methods: We analysed 178 patients with neuroendocrine tumors (NETs) treated at our department in the last five years. The diagnosis was made by pathohistological exam...

Objectives: Insulin resistance and hyperinsulinaemia are implicated in the pathogenesis of the polycystic ovary syndrome (PCOS) in the majority of the cases. Adiponectin is adipose tissue-specific protein and its correlation with insulin resistance is well established. The aim of the study was to access the correlation between adiponectin and anthropometric and metabolic parameters in a group of women with PCOS.Methods: Thirty-one women with PCOS (age: 2...

Mutation Y791F of RET protooncogene is a well known mutation so far described in families with FMTC and familial pheochromocytoma in one family. It activates the receptor in a monomeric form. Here we present eight unrelated families with the same mutation but different fenotype expression.Patients and methods: In last 20 years, we analyzed 216 patients with MTC (age range: 3–75 years, 45.0 mean). Genetic testing for mutation in RET pro...

We describe a 52-year-old woman, with acromegaly, clival chondroid chordoma, meningioma and lung carcinoid. There was no family history of MEN-1. She was diagnosed as acromegaly in 2000. Radiological evaluation (MRI) revealed pituitary tumor, however, another infiltration of scull base was detected which invaded sphenoidal and ethmoidal sinuses, lamina cribroza and bilateral orbit walls. Pituitary tumor was completely removed and the reduction of extra-sellar mass was performe...

Single nucleotide polymorphisms in the glucocorticoid receptor (GR) gene influence tissue sensitivity of GR. Several studies have shown different effects of BclI GR polymorphism on body composition and metabolic parameters. The objective of this study was to explore the effect of BclI GR polymorphism on the body composition and glucose metabolism. Biochemical tests and hormonal evaluation were performed in 106 consecutive women with adrenal incidentalomas (AI...

Introduction: Chronic endogenous hypercortisolism in Cushing’s syndrome imposes a great clinical burden of comorbidities, some of which might persist even after disease remission. Our aim was to analyze factors that predict long-term comorbidities after surgical remission of Cushing’s disease (CD).Subjects and methods: We retrospectively analyzed 37 patents (91.9% females) aged 39.5±13.9 years (10-70) with diagnosed CD, treated in our inst...

Aim: Functional neuroendocrine tumors (NETs) represent a specific diagnostic and therapeutic challenge. Hormonal clinical syndrome can severely complicate clinical picture and affect treatment. Functional pancreatic NETs have been extensively studied. Our aim was to analyze functional lung NETs in terms of clinical characteristics and survival.Materials and methods: We retrospectively analyzed data from 230 patients with lung NETs treated at our departme...

Paragangliomas (PGLs) and pheochromocytomas (PCCs) are rare neuroendocrine tumors that arise from chromaffin cells of the adrenal medulla and the sympathetic/parasympathetic neural ganglia, respectively. We retrospectively analyzed 82 patients (43 female and 38 males) predominantly with PGLs who were hospitalized between January 2002 and December 2022. Twenty one patients were lost to follow up. The median age at diagnosis was 47 years (11–75) and the mean tumor size was ...
