Background: Higher anti-Müllerian hormone (AMH) values are associated with polycystic ovary syndrome (PCOS) and AMH is proposed as a marker of PCOS, however, the optimal diagnostic threshold is not yet defined.Aim: To study the significant correlations of AMH in PCOS and the accuracy and threshold of AMH for the PCOS diagnosis in Romania.Subjects and methods: Serum AMH, TT, LH, FSH, fasting glucose and insulin (Ins), HOMA-IR a...

Introduction: Zinc homeostasis is involved in numerous physiological and pathological conditions, ranging from type 1 and type 2 diabetes to memory impairment and cancer, and is determined by at least 28 genes, including 24 SLC (Solute Carrier) family members and 4 MTs (Metallothioneins). To explore the potential role of zinc homeostasis in MetS (metabolic syndrome) and IR (insulin resistance), we investigated 28...

Introduction: Pituitary neuroendocrine tumors (PitNET) are characterized by a heterogenous behavior. The immunohistochemical (IHC) staining of anterior pituitary hormones, along with that of pituitary transcription factors and with the clinical and biochemical characteristics of the patients can be integrated in a risk stratification system, which helps the therapeutic management.Material and Methods: We analyzed 37 patients with confirmed diagnosis of a...

Introduction: Clinically non-functioning pituitary neuroendocrine tumours (NFPitNETs) include all anterior pituitary tumours that are not hormonally active. In histopathology (HP) and immunohistochemistry (IHC), most of NFPitNETs are gonadotroph (1). Immunolabeling is negative in only 10% of cases (‘null-cell’). Occasionally, NFPitNETs are positive for GH, PRL, TSH or ACTH despite absent or only minimal secretion of these hormones in vivo, which are known as...

Background: Recent data highlight the role of anti-Müllerian hormone (AMH) to trigger the neuroendocrine abnormalities involving GnRH and secretion of gonadotropins in polycystic ovary syndrome (PCOS).Aim: To study factors significantly correlated with neuroendocrine dysfunction in PCOS, with focus on AMH.Subjects and methods: We performed a cross-sectional study in 137 patients with PCOS selected by Rotterdam 2003 criteria an...

Background: Hyperandrogenism is a main feature of the polycystic ovary syndrome (PCOS). Although its ovarian origin is well recognized, laboratory investigation suggested the contribution of adrenal gland, albeit of unknown mechanism.Aim: To understand the contribution of genetic factors in adrenal hyperandrogenism (AH) we investigated genome wide SNPs in subgroups of PCOS patients stratified as function of DHEAS levels in two ethnic populations (Romania...

10% of patients with adrenal tumours have bilateral lesion.Objective: To evaluate clinical, imagistic and hormonal characteristics of bilateral adrenal tumours.Design and mehods: Retrospective series of 150 consecutive patients (104F, 46M) with bilateral adrenal tumours with maximal diameter of at least 1 cm, evaluated from 2001 to 2015 in a tertiary endocrinology clinic with clinical, hormonal and imagistic methods.<p class="a...

Background: PBMAH is a rare cause of adrenal Cushing’s syndrome, frequently due to aberrant adrenal expression of hormonal receptors.Aim: To describe 6 patients with PBMAH.Methods: Clinical, hormonal and imagistic evaluation.Results: Age at diagnosis of patients (4M/2F) was 50–79 years. One asymptomatic patient was incidentally diagnosed on abdominal CT, two patients had overt Cushing’s (centra...

Introduction: The Cushing’s syndrome associated bilateral adrenal tumours comprise a wide area of diagnosis; the therapeutic approach is challenging since unilateral intervention might involve persistent hypercotisolemia, and bilateral adrenalectomy induces chronic adrenal insufficiency. The adrenal vein catheterism is not available in many countries.Case report: 50-year old non-smoker female has the following medical history: 2 years ago she presen...
