Objective: KIMS (Pfizer International Metabolic Survey) was a postmarketing surveillance study of growth hormone (GH) replacement in adults and adolescents with GH deficiency (GHD) that concluded in October 2012. This analysis aimed to evaluate the overall safety outcomes from the full cohort of GH-treated patients of KIMS.Methods: Data were collected on adults and adolescents with confirmed GHD and closed epiphyses trea...

Growth hormone (GH) stimulates insulin like growth factor I (IGF I) release. IGF-I is the standard biomarker for monitoring GH effects during treatment and to achieve optimal long-term safety, and to a limited extent, monitor efficacy in children with GH deficiency (GHD). The IGF I profile during treatment with a long acting GH (LAGH), such as once weekly somapacitan (Novo Nordisk), differs from the daily GH profile by exhibiting larger peaks and troughs over the dosing interv...

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...

Introduction: X-linked hypophosphataemic rickets (XLH), due to mutations in the PHEX (Phosphate-regulating Endopeptidase homolog; X-linked) gene, causes reduced bone and dentin mineralisation and decreased renal phosphate reabsorption. Mosaic PHEX mutations are reported only in a few case reports.We report three male cases, with mosaic pathogenic PHEX variants, showing importance of considering this in the diagnosis of XLH.Case 1 pre...

Background and Aim: A substantial proportion of SGA patients have a syndrome underlying their growth restriction. Most SGA cohorts comprise both syndromic (S-SGA) and non-syndromic patients (nonS-SGA) impeding delineation of the recombinant human growth hormone (rhGH) response. We present a detailed characterization of the Belgian SGA cohort and analyze rhGH response based on adult height (AH).Patients & Methods: Cli...

Background/Aim: X-linked hypophosphatemia (XLH) is a rare disease caused by mutations in PHEX, leading to elevated FGF23 levels, hypophosphatemia and chronic renal phosphate wasting. Burosumab is a monoclonal antibody against anti-FGF23, which has been recently approved for treatment of XLH. Beyond clinical trials, little is known about its efficacy/safety in clinical practice which is the aim of study.Patients/Methods: ...

Background: Hereditary Hypophosphatemic Rickets (HHR) is caused by persistently elevated FGF23 resulting in renal phosphate wasting and decreased 25 vitamin D hydroxylation. Treatment with vitamin D analogues (VDA) has been added to phosphate supplements in the late seventies.Objective and hypotheses: Our objective was to evaluate the outcomes of VDA and phosphate supplements in adult patients with HHR in comparison with patients who did not receive VDA ...

Purpose: Low areal bone mineral density (aBMD) is a well-known consequence of anorexia nervosa (AN). However, the impact of reduced energy expenditure on bone metabolism is unknown. This study assessed the effects of energy deficiency on bone remodelling and its potential interactions with glucose homeostasis and adipose tissue-derived hormones in AN, a clinical model for reduced energy expenditure.Methods: 50 women with AN and 50 age-matched controls (m...

Background: The association between HNF1A-MODY and vascular complications including stroke has previously been identified in adults but to date there have been no reported paediatric cases published.Description: We present the case of an Eritrean 13-year-old girl, who was admitted with an acute ischaemic stroke, on a background of Diabetes Mellitus (Presumed Type 1) diagnosed the previous year. Aside from being on multip...

Background: Complex fluid balance problems are well established post-neurosurgery and traumatic brain injury (TBI). The triple-phase response requires fluid management strategies reactive to urine output as patients shift between DI and SIADH. Prevalence of CSW is controversial; but ensuring sodium homeostasis is central to safe fluid management. To improve clinical care for these complex patients an audit of existing institutional guidelines was undertaken. N...
