Introduction: Renal transplant receivers (RTR) have a higher risk for osteoporosis, obesity and sarcopenia, which all seem to be interrelated. FGF23 and adipokine disorders, often recognized in RTR, might be involved in the fat-muscle-bone crosstalk. The current study aims to evaluate the influence of body compartiments and adipokines on bone mass in RTR.Methods: Thiscross-sectional study investigates the predictive role of body composition, adipokines (...

Published data regarding the role of FGF23 in primary hyperparathyroidism and its prognostic applicability are scarce and discordant.Aims: To assess FGF23 profile in patients with primary hyperparathyroidism undergoing surgery.Matherials and methods: Longitudinal study involving 48 patients aged 30–80 years with primary hyperparathyroidism caused by solitary parathyroid adenoma, submitted to parathyroidectomy. We evaluated FGF...

Introduction: Chronic kidney disease (CKD) is associated with alterations in endogenous glucocorticoid regulation through various mechanisms: longer plasma cortisol half-life, reduced renal cortisol clearance, loss of 11b-HSD type 2 activity in the kidney contributing to an elevated cortisol/cortisone ratio, less effective hepatic metabolism of cortisol and, finally, hyperactivation of the hypothalamus-pituitary-adrenal axis due to acidosis, chronic stress, and inflammation.</...

Introduction: Adrenocortical carcinoma (ACC) is a rare endocrine malignancy arising from the adrenal cortex often with unexpected biological behavior. It can occur at any age, with two peaks of incidence: in the first and between fifth and seventh decades of life. Although ACC are mostly hormonally active, precursors and metabolites may be also produced by dedifferentiated and immature malignant cells.Case report: We report a rare and challenging case of...

Introduction: Turner syndrome (TS) is a chromosomal disorder that arises due to the complete or partial loss of one sex chromosome, impacting approximately 1 in every 2500 to 3000 female births. The phenotype is attributed to haploinsufficiency of genes on the X chromosome, which are resistant to inactivation. Virilizing symptoms appearing in a patient with TS advocates for an endocrine assessment and karyotyping to ascertain the virilization’s etiology, enabling prompt i...

Introduction: SARS-Cov-2 infection challenged the appropriate management of acromegaly, because of delayed or limited admissions and treatment. Despite lack of data regarding SARS-Cov-2 infection in acromegalic patients (only one case reported to date), increased susceptibility to infection and poor prognosis might be triggered by the associated metabolic, cardiovascular and respiratory comorbidities. We report a series of acromegaly patients with a positive PCR test at their ...

Introduction: Lipodystrophic syndromes are rare and heterogeneous disorders characterized by the complete or partial deficiency of adipose tissue. They can be classified according to the extent of fat loss in generalized or partial subtypes and genetic or acquired based on the pathogenic mechanisms.Case report: A 37-year-old man was referred to our department with a history of nonalcoholic steatohepatitis associated with high levels of triglycerides (720...

IntroductionBody composition (BC), adipokines and the fibroblast growth factor-23 (FGF23) - Klotho axis interfere with bone metabolism and also suffer important modifications in acromegaly. We aimed to investigate their influence upon bone in active acromegaly, compared to controls.MethodsWe performed a cross sectional study, investigating the adipokines (leptin, adiponectin, resistin) secretion pattern, BC p...

Introduction: Prolactinomas, prevalent among young women, are the most frequently encountered secreting pituitary tumors. Pituitary apoplexy is a rare and severe complication of prolactinomas, which manifests with rapid onset symptoms like severe headaches, visual disturbances, hormonal imbalances, requiring urgent medical care.Case report: We report the case of a 46-year-old female patient with history of type 2 diabetes, early menopause (30 years old, ...

Ectopic ACTH secreting syndrome is a rare cause of endogenous ACTH dependent Cushing syndrome. We aim to analyze clinical, biochemical, imaging profile, as well as management and outcomes of 7 EAS patients diagnosed in our clinic within the last 10 years, based on clinical presentation, hypercortisolism, high ACTH levels, specifically over 100pg/ml, with failed high dose dexamethasone suppression test. Clinical presentation was characteristic in 5 of the patients, but 2...
