Long-Term Insulin Sensitivity and β-Cell Function in Short Children Born Small for Gestational Age Treated with GH and GnRHa: Results of a Randomised, Dose-response Trial

van der Steen Manouk , Lem Annemieke J , van der Kaay Danielle C M , Hokken-Koelega Anita C S

Background: Pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (2 years GnRHa) and even more so with 2 mg/m2 per day (~0.067 mg/kg per day). Concerns haven been raised about the effects of GH and GnRHa on insulin sensitivity on the long-term.Objective and hypotheses: To ...

Pubertal Development During GH Treatment with or without Additional GnRH Analogue Treatment in Short Children Born Small for Gestational Age

van der Steen M , Lem A J , Hokken-Koelega A C S

Background: GH treatment is effective in improving adult height (AH) in short children born Small for Gestational Age. If SGA children are short at the start of puberty, they could benefit from combined GH/GnRH Analogue (GnRHa) treatment.Objective and hypotheses: To determine the timing and progression of pubertal development in short SGA children, comparing GH treatment with combined GH/GnRHa treatment.Method: For the present stud...

E-Learning in Paediatric Endocrinology and Diabetes in Resource Limited Countries (RLC)

Boot Annemieke

The structure and design of the ESPE web portal (www.espe-elearning.org) is based on facilitating Problem-Based Learning (PBL). It consists of carefully designed problems that challenge medical students, residents, postdoc’s to use problem solving techniques, self-directed learning strategies and specialty knowledge.The ESPE e-learning web portal is an interactive learning environment for up to date topics in pediatric endocrinology and diabetes co...

Metabolic Health in Short Children Born Small for Gestational Age Treated with GH and GnRHa: Results of a Randomised, Dose-response Trial

Background: Previously we showed that pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (GnRHa) and even more so with a double GH dose. GnRHa treatment is thought to have negative effects on body composition and blood pressure. Long-term effects and GH-dose effects on metabolic health in children treate...

A patient-centred and multi-stakeholder co-designed, mixed methods, observational, prospective study protocol: Example of the adolescent experience of treatment for X-linked hypophosphatemia (XLH)

Saraff Vrinda , Arango-Sancho Pedro , Bacchetta Justine , M. Boot Annemieke , P. Burren Christine , Chinoy Amish , Dharmaraj Poonam , David González-Rodríguez Juan , Gueorguieva Iva , Hayes Wesley , Linglart Agnès , Amelia Gómez Llorente Maria , Ríos Héctor , Schnabel Dirk , Harvengt Pol , M.A. Bailey Karen , Glen Fiona , J. Rylands Angela , Williams Angela , Haf Davies Elin

Background: XLH is a rare, genetic, life-long disease caused by PHEX pathogenic variants. It is associated with progressive accumulation of musculoskeletal features and symptoms that evolve across the patient’s lifetime if untreated. Although the disease is well characterised in children and adults, there are limited data describing the health outcomes and experiences of adolescents, particularly at end of skeletal growth (EOSG), a crucial phase during t...

First interim analysis of the International X-Linked Hypophosphataemia (XLH) Registry: Baseline characteristics of children treated with conventional therapy and burosumab

Boot Annemieke , Liu Jonathan , Williams Angela , Wood Sue

Objectives: X-linked hypophosphataemia (XLH) is a rare, hereditary phosphate-wasting disorder characterised by excessive activity of fibroblast growth factor 23. The International XLH Registry (NCT03193476) (initiated in August 2017, target 1,200 children and adults with XLH, running for 10 years) will provide information on the natural history of XLH and impact of treatment on patient outcomes. This report summarises baseline data from the first interim analy...

Disproportionate Short Stature with Advanced Bone Age Due to PTHLH Mutation

Boot Annemieke , Stolte-Dijkstra Irene , Veenstra-Knol Irma

Background: Skeletal dysplasia is the main cause of disproportionate short stature. The severity may vary. The present patient had disproportionate short stature with brachydactyly.Patient and method: A boy of 5 years old presented with height 108.9 cm (−1.8 S.D.), sitting height/height ratio was +3.4 S.D., short hands and feet with short metacarpal 4 and metatarsal 4 on both sides. He had increased lumbar lordosis and...

The effect of storage and temperature on the stability of steroid hormones in dried blood spots

Olthof Anouk , Wickenhagen Wjera , Hillebrand Jacquelien , Boelen Anita , Heijboer Annemieke

Introduction: Monitoring steroid hormone levels of children with endocrine disorders, such as congenital adrenal hyperplasia (CAH) and disorders of sex development (DSD), can be challenging. Dried blood spot (DBS) sampling can be helpful for these patients. DBS sampling is less invasive, easier to sample, and simpler to transport and store compared to venous blood sampling. Additionally, DBS sampling can be done at home at any time of the day, thus improving p...

Very preterm infants developing BPD have increased levels of the cortisol precursors 17-OH progesterone and 11-deoxycortisol

Romijn Michelle , Onland Wes , van Keulen Britt , Heijboer Annemieke , Rotteveel Joost , van Kaam Anton , Finken Martijn

Rationale: Bronchopulmonary dysplasia (BPD) is a major complication of preterm birth, which pathophysiology involves systematic inflammation. Preterm infants commonly suffer from relative adrenal insufficiency (RAI) in their first week of life, resulting in an insufficient production of cortisol inappropriate for the degree of inflammation. One of the major causes of RAI is immaturity of adrenal cortex enzymes, leading to an accumulation of cortisol precursors...
