Aim: To assess cumulative incidence and risk factors for amiodarone-induced thyroid dysfunction (AITD) in a large cohort of Romanian subjects.Subjects and methods: One hundred and forty-four patients (59 M/85 F), mean age 61.4±0.9 years, treated 2.4±0.2 years with amiodarone were assessed for TSH, TT3, TT4 (immunoradiometric assays) and FT4, TPO Ab (microenzymatic immunoassays). Thirty-three patients were reside...

Background: Primary aldosteronism is associated with increased vascular mortality and morbidity.Aims: We aimed to assess metabolic and hormonal profile differences in patients with primary aldosteronism (PA) compared with patients with essential hypertension (EH).Patients and methods: Thirty-one patients (11 M/20 F) with primary aldosteronism, aged 46.2±12.9 years and 64 patients (24 M/40 F) with essential hypertension, aged 4...

BackgroundFluid balance in patients with diabetes insipidus and COVID-19 is very fragile. The prevalence of hyponatraemia in patients with pneumonia due to COVID-19 seems to be low, but in patients admitted to intensive care units (ICU) is high (up to 20.5%). In contrast, hypernatraemia may also develop in COVID-19 patients in ICU (up to 3.7% of cases), due to insensible water losses from pyrexia, increased respiration rate and use of diuretics. Both hyp...

Background: PTH is a hormone with vascular and cardiovascular properties, involved in the expression of endothelial pro-atherosclerotic and pro-inflammatory parameters. Both hypercalcemic and normocalcemic primary hyperparathyroidism (PHPT) were associated with increased cardiovascular risk.Patients and methods: 84 patients (6M/78F) with PHPT, aged 58.9±12.7 years, were retrospectively reviewed. Serum calcium levels, PTH and 25 OH vitamin D levels w...

Background: Cushing’s syndrome is represented by the cummulation of signs and symptoms of excess glucocorticoids and has many potential causes. Approximately 20 percent of all cases are represented by ACTH-independent adrenal tumors – with a majority of these being represented by cortisol secreting adrenal adenomas. Generally, a large adrenal tumor has over 5 cm in diameter and the risk of it being malignant raises proportionately with the dimensions. Large adrenal t...

Background: Dopamine agonists (DA) have excellent result in controlling both hyperprolactinemia and tumor volume in macroprolactinomas. However, even after long term DA treatment, withdrawal of dopamine agonists results in recurrence of hyperprolactinemia in a significant proportion of patients.Aim: To assess recurrence rate of hyperprolactinemia after DA withdrawal in a large series of patients treated in a tertiar...

Background: Prolonged ingestion of licorice has been known to cause hypokalemia and resistant hypertension amongst other disturbances. This is due to glycyrrhizin that inhibits the 11-β-hydroxysteroid dehydrogenase enzyme type 2 which results into increased plasma cortisol levels that stimulate the mineralocorticoid receptors resulting into apparent mineralocorticoid excess.Case report: A 45-year-old woman resident in an iodine sufficient area, heav...

Introduction: There is evidence that SARS-COV-2 infection can result in development of endocrine disturbances. Expression of the angiotensin-converting enzyme 2, which is postulated to be at the center of the pathogenesis of COVID-19, has been reported in various endocrine tissues.Case Series: We retrospectively analyzed 12 patients with recent history of SARS-COV-2 infection: 5 cases with subacute thyroiditis (SAT), 2 cases with Graves’ disease, 2 ...

Background: Dopamine agonists (DA) are the first-line treatment for macroprolactinomas. However, up to 10% of patients fail to respond to medical therapy.Aim: To assess biochemical resistance rate to DA treatment in a large series of patients with macroprolactinoma and to analyze possibilities to overcome this resistance.Patients and methods: 195 patients with macroprolactinomas, treated with DA for at least 2 years, were retrospec...
