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 ...

Introduction: Increased adrenal androgen production is present in 20–60% of women with polycistic ovary syndrome (PCOS). Possible mechanism is not clarified yet and could be related to altered hypothalamic-pituitary-adrenal-axis (HPA) activity or a consequence of adrencortical steroidogenic abnormalities. The aim of the study was to assess HPA sensitivity in PCOS women using different doses of dexamethasone.Methods: We analyzed 359 women with PCOS d...

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...

Clinical characteristics and survival of patients with paraganglioma: a single center experience

Elezovic Valentina , Macut Djuro , Ognjanovic Sanja , Isailovic Tatjana , Popovic Bojana , Bozic-Antic Ivana , Bogavac Tamara , Ilic Dusan , Bankovic Jovana , Damjanovic Svetozar

Paragangliomas (PGLs) and pheochromocytomas (PCCs) are rare neuroendocrine tumors that derived from pluripotent neural crest stem cells. PCCs are derived from the adrenal medulla, while PGLs are histologically identical tumors derived from ganglia outside the adrenal gland. Even though the majority of tumors are benign, they are associated with high morbidity rates caused by excessive catecholamine secretion. We retrospectively analyzed 71 patients (36 female and 35 males) wit...

Pancreatic neuroendocrine tumors (PNETs) in patients with MEN1 syndrome

Isailovic Tatjana , Macut Djuro , Ognjanovic Sanja , Petakov Milan , Elezovic Valentina , Milicevic Ivana , Popovic Bojana , Antic Ivana Bozic , Bogavac Tamara , Ilic Dusan , Damjanovic Svetozar

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 ...

Biology and differential diagnosis of calcitonin secreting neuroendocrine tumors

Popovic Bojana , Macut Djuro , Elezovic Kovacevic Valentina , Isailovic Tatjana , Bozic Antic Ivana , Bogavac Tamara , Ilic Dusan , Ognjanovic Sanja , Rodic Gordana , Petakov Milan , Damjanovic Svetozar

Introduction: Calcitonin secreting neuroendocrine tumors (NET) are rare and not well recognized. Due to many similarities, it is sometimes difficult to differentiate them from medullary thyroid carcinoma (MTC), which can hamper choice of proper therapy. We investigated our group of patients with this type of NET in terms of diagnosis and biology.Patients and Methods: We analyzed 38 patients with calcitonin secreting NET (5% of all our patients with NET)....

Introduction: Recently, it was suggested that insulin resistance index using C-peptide (CIR) could be a better marker of insulin resistance than homeostasis model assessment (HOMA-IR) in patients with type 2 diabetes mellitus. The aim of this study was to investigate performance of CIR index in PCOS subjects.Methods: We evaluated 187 PCOS women (PCOS: 25.38±6.32 kg/m2; 26.01±5.16 years) diagnosed using ESHRE/ASRM criteria and 42 heal...

Glucose level after standard oral glucose tolerance test as a potential marker for the development of type 2 diabetes in women with polycystic ovary syndrome (PCOS)

Introduction: It has been shown that subjects with normal fasting glucose (NFG) and normal glucose tolerance (NGT), whose plasma glucose concentration does not return to their fasting plasma glucose (FPG) level within 2 h following standard oral glucose tolerance test (OGTT), have higher risk of progression into type 2 diabetes (T2D) than NFG/NGT subjects whose glucose returns to FPG level after OGTT. Although the development of T2D during the life of woman with polycystic ova...

Introduction: Polycystic ovary syndrome (PCOS) phenotypes A and B are considered to be more hyperandrogenic in comparison to phenotypes C and D that are considered to be mostly reproductive. The aim of this study was to analyze distribution of androgens in different phenotypes in our PCOS population.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 healthy women...
