Evaluation of copeptin levels during glucagon stimulation test in children with suspected growth hormone deficiency

Ferrante Emanuele , Giacchetti Federico , Indirli Rita , Profka Eriselda , Rodari Giulia , Giavoli Claudia , Mantovani Giovanna , Arosio Maura

Introduction: Glucagon stimulation test is one of the recommended growth hormone provocation tests for diagnosing growth hormone deficiency in children. In adult patients, recent data showed that glucagon administration is able to stimulate the release of copeptin, the stable C-terminal glycopeptide of the AVP prohormone whose evaluation during hypertonic saline infusion represents the gold standard for the differential diagnosis of polyuria/polydipsia. However, similar data o...

Bone and sexual health in adult women with complete androgen insensivity syndrome: A single centre experience

Profka Eriselda , Rodari Giulia , Giacchetti Federico , Giavoli Claudia , Arosio Maura , Mantovani Giovanna

Background: Low bone mineral density (BMD) and reduced sexual satisfaction have been reported in complete androgen insensitivity syndrome (CAIS). Nevertheless, conclusive data on the prevalence and on the optimal management of these conditions are still lacking.Aims: To assess bone and sexual health in adult women with CAIS with and without gonadectomy.Methods: Single-centre, prospective study of 27 adult CAIS (age 35.2±8.7 ye...

In between isolated premature thelarche and central precocious puberty: when DHEAS makes the difference

Rodari Giulia , Collini Valentina , Giacchetti Federico , Profka Eriselda , Arosio Maura , Mantovani Giovanna , Giavoli Claudia

Background: Precocious puberty (PP) in girls is most frequently an idiopathic gonadotropin-releasing hormone (GnRH)-dependent PP, being thelarche the typical first sign. It is well established that increased dehydroepiandrosterone sulphate (DHEAS) levels are associated with premature adrenarche and may characterize PP too. However, its relationship with signs of hypothalamic-pituitary-gonadal (HPG) axis activation and oestrogen exposure is still to be elucidated.<p class="...

Deletion of chromosome 1q24-1q32 and combined pituitary hormone deficiency type 4: Insight into the challenges of genotype-phenotype correlation

Giavoli Claudia , Ubertini Graziamaria , Giacchetti Federico , Rodari Giulia , Profka Eriselda , Cianfarani Stefano , Arosio Maura , Cappa Marco

Background: Interstitial deletions of the long arm of chromosome 1 are rare and classified as proximal or intermediate, the intermediate spanning bands 1q24–1q32. This region contains several genes, including LHX4, a LIM-homeodomain transcription factor essential in the early steps of pituitary ontogenesis. Indeed, mutations in the LHX4 gene are related to combined pituitary hormone deficiency type 4 (CPHD4, OMIM 602146).Aim: outline the impact of ...

Baseline IGF-I values influence the effect of rhGH therapy on fat mass: Short, medium and long term study on adults with GH deficiency

Profka Eriselda , Rodari Giulia , Giacchetti Federico , Draghi Alessandro , Arosio Maura , Giavoli Claudia

Background: One of the main effects of growth hormone therapy (rhGH) in the adult GH deficient patient (AGHD) is to positively modify body composition, with a reduction in fat mass (BF) and an increase in total lean mass (LM). However, the response to replacement therapy is highly variable and, contrary to what described in children, the potential predictive factors are not yet known.Aim of the study: To assess the impact of basal IGF-I levels on variati...

Controversies in the spectrum of GH-IGF-I axis disorders requiring replacement therapy

Rodari Giulia , Cavenaghi Ivan , Profka Eriselda , Giacchetti Federico , Arosio Maura , Giavoli Claudia

Background: Growth hormone deficiency (GHD) is the most frequent endocrinological disorder inchildren with short stature, but there are significant controversies in the diagnosis due to lack of reliablediagnostic criteria. Moreover, at final height (FH) attainment, many subjects diagnosed withisolated GHD re-test normal. It is not clear whether this represents a form of transient GHD or a false positive diagnosis during childhood.Aim: To evaluate differe...

Growth hormone deficiency and recombinant hGH (rhGH) replacement in children with idiopathic isolated GH deficiency: effects on the hypothalamus-pituitary-adrenal axis

Bergamaschi Silvia , Giavoli Claudia , Ferrante Emanuele , Rusconi Roberto , Lania Andrea G , Spada Anna , Beck-Peccoz Paolo

Cortisol and cortisone are interconverted by type 1 and type 2 11ßhydroxysteroid dehydrogenase (11ßHSD) isoenzymes. The type 1 isoenzyme is a widely expressed reductase that converts cortisone to cortisol regulating glucocorticoid tissue exposure. Its activity is inhibited by GH and IGF-I, being increased in GH deficiency (GHD) and decreased in acromegaly. In our experience rhGH therapy unmasked a central hypoadrenal state in adults with organic GHD, likely by normal...

Growth hormone replacement therapy and metabolic parameters in adult-onset GH-deficiency: long-term effects.

Giavoli Claudia , Ferrante Emanuele , Bergamaschi Silvia , Cristina L Ronchi , Francesca Doanadio , Andrea Lania , Anna Spada , Paolo Beck-Peccoz

Aim of this study was to evaluate the impact of rhGH treatment on glucose and lipid metabolism in in 26 patients (17M and 9F, age 47.0±11.1 years) with adult onset GH deficiency. Metabolic parameters (fasting glucose and insulin, glycated haemoglobin, lipid profile, body composition, OGTT) and indices of insulin resistance (IR) and sensitivity (IS), i.e. homeostasis model assessment (HOMA-IR and derived ISI-HOMA), quantitative insulin check index (QUICKI), ISI-composite, ...

Long-term evaluation of hypotalamic-pituitary-adrenal (HPA) axis in acromegalic patients during somatostatin analogs therapy and after successful surgery

Ronchi Cristina L , Rizzo Erica , Ferrante Emanuele , Giavoli Claudia , Lania Andrea G , Beck-Peccoz Paolo , Spada Anna

Long-term effects of trans-naso-sphenoidal surgery (TNS) and long-acting somatostatin analogs (SSTa) on hypotalamic-pituitary-adrenal (HPA) function have been poorly investigated. Aim of the study was to evaluate over time the integrity of HPA axis in acromegalic patients with baseline preserved adrenal function and treated with one or both available treatments. We selected 23 patients (15F & 8M, age (±S.D.)=46.8±13.7 yrs) with normal (n=19)...

Pubertal induction in girls with hypogonadism: insight into estrogen replacement therapy outcomes and optimization of progesterone introduction

Rodari Giulia , Federici Silvia , Cattoni Alessandro , Todisco Tommaso , Ubertini Graziamaria , Giacchetti Federico , Profka Eriselda , Dall'Antonia Alberta , Cangiano Biagio , Arosio Maura , Bonomi Marco , Cappa Marco , Giavoli Claudia

Background: Pubertal induction in girls with hypogonadism through estrogen replacement therapy (ERT) aims at mimicking physiological puberty. To date, the best induction regimen is still to be established.Aims: By setting up a multicentre clinical registry, we analysed longitudinal data on pubertal induction in girls with hypogonadotropic hypogonadism or premature ovarian insufficiency (congenital, acquired, isolated or associated with multiple pituitary...
