The most frequent side effects of antithyroid drugs are skin reactions (6%), gastrointestinal effects (5%) and arthralgia (5%). Other complications such as antithyroid arthritis syndrome (1%), agranulocytosis (0.5%) and hepatitis (0.2%) occur rarely.We describe the case of a 20-year-old woman with Graves’ disease. Two weeks after the beginning of carbimazole therapy, she developed an urticarial reaction that led to discontinuation of treatment. Neve...

Background: Pasireotide is a second line treatment for acromegaly. Besides the growth hormone (GH) lowering efficacy, clinical use is limited by side effects on glycemic control. The aim of this study was to evaluate longitudinal changes in beta-cell function and insulin sensitivity induced by pasireotide therapy in patients with acromegaly.Methods: We performed a retrospective study in 33 patients. Efficacy (GH and IGF-I concentrations; tumor size) and ...

Introduction: Usually GHD women require higher GH doses than males, especially those with exogenous oestrogens (guidelines). This fact was assessed in real-life practice in France.Methods: Data were from a Registry in 84 sites treating AGHD (Norditropin®) up to 5 years. Naïve patients did not receive GH 6 months before inclusion. Statistics were descriptive.Results: 328 patients (129 naïve) were included; mean age 49...

Background: Cabergoline (CAB) is the most effective dopamine agonist (DA) used for the treatment of macroprolactinoma. Few data on the dose of CAB necessary for achieving and maintaining normal prolactin (PRL) levels are available. We aimed to study these parameters in a large series of patients with macroprolactinomasMethods: We retrospectively analysed the clinical, biochemical and imaging features at diagnosis and the treatment response to CAB (dose n...

Context: Insulin-like peptide three (INSL3) is a testicular hormone, secreted by Leydig cells, during fetal life, in newborns, and after puberty. These 3 phases of testicular activation are impaired in CHH.Objective: To evaluate in a single center circulating INSL3 in a significant series of men with CHH in order to asses the consequences of pre- and postnatal gonadotropin deficiency, to specify the INSL3 regulation by gonadotropins and to evaluate the p...

Context: Mitotane due to its adrenolytic action is highly effective in long-term management of ACTH-dependent Cushing’s syndrome (CS). However, the slow onset of its anticortisolic effect makes its use problematic in severe CS, when very rapid therapeutic response is required. Association with metyrapone and ketoconazole, rapidly acting steroidogenesis inhibitors, could warrant CS control while waiting for the full efficiency of mitotane and thus avoid urgently performed ...

Objective: IGF1 is the most useful serum marker for GH dose titration in adults. The authors focused on the GH dose adjustment with extreme IGF1 values (<−2S.D.; >+2S.D.).Methods: French observational study of AGHD patients treated with Norditropin®.Prospective follow up until 5 years.Results (median [Q1; Q3]):: 328 AGHD, 39.2±14.3 years old wer...

Context: Cervical ultrasound is a frequently used and an accessible operator-dependent tool, which contributes to the characterization of thyroid nodules and to the preoperative localization of pathological parathyroid glands. However, thyroid nodules may be confused with parathyroid lesions. There is no study directly comparing thyroid and parathyroid nodules on ultrasound.Objectives: 1) To describe the ultrasonographic characteristics of parathyroid le...

Context: Hypogonadotropic hypogonadism (HH), defined by LH and FSH deficiencies, lead to impairment in testicular growth, testicular hormonal secretions and spermatogenesis. HH can have a prenatal (congenital HH, CHH) or post-natal (acquired HH, HHA) onset. Direct comparison of reproductive phenotypes (RP) between CHH and AHH has not been systematically performed in large series representative of these two populations.Patients and methods: 60 normal men,...

Context: Congenital hypogonadotropic hypogonadism (CHH), is a rare disorder associated with severe testosterone deficiency and with impaired bone mineral mass (BMM) acquisition and osteoporosis. Estradiol (E2) play a major role in bone development and maintain in BMM in humans.Objective: To evaluate in detail the degree of E2 deficiency in adult men with CHH.Design and patients: Using a sensitive E2...
