Pegvisomant is More Effective in Stunting Growth than Somatostatin Analogs in Childhood Acromegaly/Gigantism

Thomas-Teinturier Cecile , Simonin Gilbert , Vaczlavik Anna , Ajaltouni Zaina , Gaillard Stephan , Bougneres Pierre , Chanson Philippe

Background: We describe our experience in medical therapy for invasive somatotroph pituitary macroadenomas in 8 children or adolescents presenting with acromegaly/gigantism, in terms of growth and IGF-I levels control.Patients: Eight children, aged 5 to 17 years (median 12.4 years), presented with growth hormone (GH) hypersecretion related to somatotroph pituitary macroadenomas with cavernous sinus invasion in 6/8. Genetic testing revealed AIP mutation i...

Pegvisomant in Child Acromegaly

Anna Vaczlavik , Cecile Teinturier , Stephan Gaillard , Pierre-Francois Bougneres , Philippe Chanson

Background: Acromegaly is a rare childhood disorder. The use of a growth hormone (GH) receptor antagonist, pegvisomant, has shown great results in adults with acromegaly. We describe results of pegvisomant therapy in two girls with invasive GH pituitary macroadenomas.Case presentation: Case 1: A somatotroph pituitary macroadenoma was diagnosed in a 8-year-old girl with progressive tall stature (height: 148 cm, >+3 S.D.; growth velocity...

Background: Hereditary hypophosphatemic rickets (HHR) is a rare genetic disease characterized by renal phosphate wasting, caused by elevated circulating FGF23. Despite the current available treatment complications include short stature, hyperparathyroidism, pseudofractures, bone pain, bone demineralization and osteoporosis, nephrocalcinosis and enthesopathies. Elevated circulating FGF23 was recently involved in glucose metabolism and cardiovascular function.<p class="abste...

Purpose: Isolated growth hormone deficiency (IGHD) is a rare condition mainly caused by mutations in GH1. The aim of this study was to assess the contribution of GHRHR mutations to IGHD in a very large cohort of patients.Methods: All GHRHR coding exons and flanking intronic regions were sequenced in 312 unrelated patients with non-syndromic IGHD. Functional consequences of all newly identified missense variants were assessed <e...

Background: Prenatal dexamethasone treatment (Pdex) has been used since the 1980s to prevent virilization in female offspring suspected to have congenital adrenal hyperplasia (CAH). However, due to lack of strong evidence for its best practice as well as limited data regarding long term adverse effects, use of dex is highly controversial. This study reveals the current medical practice regarding Pdex in female fetuses at risk of CAH due to 21 hydroxylase defic...
