Objective: To assess the outcome of medical and ablative therapies in amiodarone-induced thyrotoxicosis (AIT).Subjects and methods: Seventy patients (32 M/38 F, aged 59.7±1.4 years) with AIT (24-type 1, 20-type 2 and 26-mixed forms) were followed-up 13.4±2.3 months. TSH was measured by immunoradiometric assay, TT3 and TT4 by chemiluminescence.Results: Antithyroid drugs (ATD) were used as single thera...

Carcinoma of the thyroid gland is an uncommon cancer but is the most common malignancy of the endocrine system. The treatment of the thyroid cancer includes surgery, radioactive iodine and hormone treatment. Postoperative hypothyroidism is the most common complication of thyroidectomy for thyroid cancer. After thyroidectomy, the patient takes a thyroid hormone drug (levothyroxine) in supresive dose for the rest of his life.In hypothyroidism there has bee...

Generously supported by IPSEN)-->Treatment with hormone analogues can challenge the precise measurement by interference with the routinely used immunoassays systems, related to the presence of autoantibodies in the serum, interference with associated therapy or the presence of altered forms of the hormone, with modified biological activity and/or immunoreactivity.In patients with acromegaly treated with the hGH...

In acromegalic patients growth hormone (GH) excess induces insulin resistance but whether this is sufficient, in the face of normal insulin secretion, for pre-diabetes (impaired fasting glucose (IFG) and impaired glucose tolerance (IGT)) to occur is a matter of debate.Aim: To assess the relative role of insulin resistance and insulin secretion in the pre-diabetes of acromegaly.Methods: One hundred and twenty-four patients with acro...

Lanreotide has long been used in the therapy of GH secreting pituitary adenomas and other somatostatin receptor positive neuroendocrine tumors.Aims: To determine the impact on glucose metabolism of the 6 months of lanreotide therapy, beside of the antisecretory and antiproliferative effects.Patients and methods: Seven patients with active acromegaly treated with lanreotide, admitted in the Department of Neuroendocrinology, Institut...

Aim: To set up, in acromegaly without diabetes mellitus, a correlation between the disease activity in GH-secreting adenoma (AA) - assessed by minimum GH serum level during an oral glucose tolerance test (OGTT) - and severity of insulin resistance (IR), assessed by HOMA-IR index.Methods: 75 out of 88 consecutive patients with acromegaly hospitalized in our department were included in this study. 13 patients proved to have diabetes mellitus and were exclu...

Introduction: Excess GH in acromegaly has lipolytic action and detrimental effect on glucose metabolism and insulin signaling. Recent studies have suggested a specific lipodystrophy in patients with acromegaly. Paradoxically, although the visceral adipose tissue (VAT) and intrahepatic lipid were reduced in active acromegaly compared to controls, insulin resistance was increased. Fat was redistributed from subcutaneous and visceral depots to muscle; weight and VAT depots rose w...

Background: Prevalence and type of amiodarone-induced thyroid dysfunction in a population depend on geographical iodine intake.Aims: To assess differences in amiodarone-induced thyrotoxicosis pattern before and after iodine supplementation.Patients and methods: 84 patients (41M/43F) with amiodarone-induced thyrotoxicosis, aged 60.1±11.9 years, were retrospectively reviewed. 28 patients were resident in former iodine-deficient ...

Introduction: An improvement of survival in patients with acromegaly was claimed in the last years, with multimodal new therapies.Aims: To assess cure rates of different therapeutic protocols and the impact of these therapies on survival.Methods: 334 patients (224 F/110 M, mean age 48.1±0.7 years) with acromegaly admitted in a single Neuroendocrinology Department between Jan 2001 and Dec 2013 were retrospectively studied by GH...

Introduction: Struma ovarii is a rare condition which elicited considerable interest because of its many unique features like its relationship to teratoma and differentiated thyroid cancer. The most common thyroid carcinomas to arise in struma ovarii are papillary and follicular.Objectives: We describe two patients with differentiated thyroid carcinoma originating from malignant struma ovarii.Results: Our index patient is a 32-year...
