Aim: To identify the distinctive features of GH Deficiency (GHD) and to assess the response to GH treatment (rhGH) in children with Septo-Optic-dysplasia (SOD) and Multiple Pituitary Hormone Deficiencies (MPHD).Methods: Retrospective longitudinal single centre study of children with SOD (n:171) and MPHD (n:53). GHD was diagnosed in patients with growth failure by an insufficient GH response (≤6.7 μg/l) to provocation (Insulin Induced Hypoglyca...

Background: Children with septo-optic dysplasia (SOD) and related disorders can present with either hypogonadotropic hypogonadism or precocious puberty. This phenotypic variability remains unexplained.Objective and hypotheses: To compare pubertal characteristics of SOD with isolated congenital hypopituitarism (CPHD) and optic nerve hypoplasia (ONH).Method: Retrospective longitudinal data collection from 259 patients with: SOD (...

Background: Studies have suggested that sirolimus might be diabetogenic, mostly in kidney transplant recipients. Sirolimus has now been shown to be effective in the management of patients with congenital hyperinsulinism (CHI). However to date, there are no publications regarding the diabetogenic effect of Sirolimus in CHI patients.Objective and hypotheses: To report the first case of sirolimus precipitating diabetes in a CHI patient with known genetic mu...

Introduction: Septo-optic dysplasia (SOD) is characterized by a combination of midline forebrain, pituitary and eye abnormalities. We aimed to evaluate endocrine features of patients with SOD, and multiple pituitary hormone deficiencies (MPHD).Design: Retrospective data were collected from 130 patients: 102 SOD and 28 MPHD followed at a single tertiary centre. SOD were divided into two groups: with pituitary hormone deficiencies (SOD+, n=83) and...

Background: In congenital hyperinsulinism (CHI) there is dysregulation of insulin secretion that leads to hypoglycaemia. It is possible that other pancreatic hormones are also dysregulated in CHI.Objectives: i) To verify the utility of Luminex Multiplex to determine pancreatic hormones in the paediatric age. ii) To investigate the response of pancreatic hormones (insulin, C-peptide, glucagon, amylin and PP) to a fast in children with CHI due to different...

Background: Only a few case reports have described isolated postprandial hyperinsulinaemic hypoglycaemia (PPHH) in children.Objectives: To describe a single tertiary paediatric centre’s experience in the management of isolated PPHH.Patients and methods: Six children (three females) were identified. A retrospective review of the clinical characteristics, diagnosis, management and follow-up of patients with PPHH was performed. I...

Backgound: There is insufficient knowledge about the characterisation of insulin, glucagon, amylin, pancreatic polypeptide (PP) and Pancreas/Duodenum Homeobox Protein 1 (PDX-1) in pancreatic tissue of children with diffuse (DCHI) and focal (FCHI) congenital hyperinsulinism (CHI).Objective(s): To understand the expression profile and localisation of insulin, glucagon, amylin, PP and PDX-1 in pancreatic tissue of children with DCHI and FCHI.<p class="a...

Objective(s): To understand how plasma concentrations of pancreatic (glucagon, amylin, pancreatic polypeptide (PP), insulin) and gut hormones ‘incretins’ (Glucagon-like peptide 1 (GLP-1) and Glucose dependent insulinotropic peptide (GIP)) change in relation to fasting and feeding (different types of nutrients) in healthy and hyperinsulinaemic hypoglycaemia (HH) children of different ages.Methods: Plasma pancreatic and incretin hormone concentra...

Background: Case reports have documented variable glycaemic response to the mTOR inhibitor Sirolimus in severe diazoxide+/−octreotide unresponsive forms of congenital hyperinsulinaemic hypoglycaemia (CHI). A high incidence of adverse effects has been reported in patients receiving this medication.Objective(s): To describe the efficacy and safety of Sirolimus use over a 5-year period in the largest cohort of CHI patients treated to date.<p class...

Background: Few studies have described the phenotypic spectrum of Septo-Optic Dysplasia (SOD). The aim of this study was to evaluate the range of H-P structural abnormalities and the endocrine morbidity of children with SOD and related disorders.Methods: Retrospective longitudinal single centre study of children with SOD (n:171), Multiple Pituitary Hormone Deficiency (MPHD) (n:53) and Optic Nerve Hypoplasia (ONH) (n:35).<p class="ab...
