Nephrocalcinosis in Children with X-Linked Hypophosphatemia: Prevalence and Risks Factors

de Truchis Camille , Zhukouskaya Volha , Auger Martin , Rothenbuhler Anya , Linglart Agnès , Grapin Mathilde

X-linked hypophosphatemia (XLH) is diagnosed in children with clinical and or radiological signs of rickets, impaired growth velocity, low serum phosphate levels associated with renal phosphate wasting, in the absence of vitamin D or calcium deficiency. Conventional treatment is made of phosphate and active vitamin D. However, nephrocalcinosis has been identified as a complication of this therapy. Its prevalence is about 25-40% in adult XLH treated patients. It was never c...

Long-term Teriparatide (rhPTH) Treatment in Children with Syndromic Hypoparathyroidism

Buganza Raffaele , Tuli Gerdi , Matarazzo Patrizia , Tessaris Daniele , De Sanctis Luisa

Background: Hypoparathyroidism is characterized by absence or inadequately low circulating concentrations of parathyroid hormone, resulting in hypocalcaemia, hyperphosphataemia and elevated fractional excretion of calcium in the urine. The use of activated vitamin D analogues and calcium supplements are recommended as the primary therapy. To avoid vitamin D and calcium side effects, subcutaneous recombinant human parathormone [rhPTH (1-34)] has been proposed f...

Effect of Feeding Mode on Longitudinal Body Composition in Early Life

de Fluiter Kirsten S , van Beijsterveldt Inge ALP , Acton Dennis , Hokken-Koelega Anita CS

Background: Excessive gain in fat mass (FM) during the first months of life, known as the critical window for adiposity programming, is associated with an increased risk for adiposity and cardiovascular diseases in later life. Early life nutrition (breastfeeding or formula feeding) might influence body composition (FM and fat free mass (FFM)) development in early life.Aims: To investigate differences in sex-specific long...

Evaluation of Bone Health in Adolescents and Young Adults After Allogeneic Human Stem Cell Transplantation in Childhood: A Single Center Cross-Sectional Study

De Waele Kathleen , Tack Lloyd , Bordon Victoria , Van Lancker Sophie , Dhooge Catharina , Cools Martine

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Shpitzer Hana , Lazar Liora , Shalitin Shlomit , Phillip Moshe , de Vries Liat

Background: Data on the course of puberty and pubertal growth in boys with Type 1 diabetes (T1D) are sparse.Objectives: To study the course of puberty, pubertal growth and final height in boys with T1D as well as possible factors affecting these.Methods: In this retrospective longitudinal study, 68 boys diagnosed with T1D between 1996-2009 who were pre-pubertal at diagnosis and had...

Plasma Copeptin Distribution in the Pediatric Age: A Useful Diagnostic Tool for AVP-Related Disorders

Tuli Gerdi , Tessaris Daniele , Buganza Raffaele , Matarazzo Patrizia , De Sanctis Luisa

Introduction: Copeptin is a stable AVP surrogate, secreted in equimolar relationship, who has been proposed for the diagnosis of AVP-related hypo and hypernatremic disorders, i.e. the syndrome of inappropriate ADH secretions (SIADH), the cerebral/renal salt wasting syndrome (C/RSW) and diabetes insipidus (DI). Few data exist about the normal ranges for plasma copeptin levels in the pediatric age, reported between 2.4-8.6 pmol/L. The aim of this study is to rep...

Fludrocortisone Treatment in a Child with Postural Orthostatic Tachycardia Syndrome (POTS): A Case Report

Varriale Gaia , Greco Marco , De Simone Luciano , Pozzessere Anna , Stagi Stefano

Background: Postural orthostatic tachycardia syndrome (POTS) is a multifactorial condition, which implies symptoms as fatigue, tachycardia, sleep disorders and autonomic symptoms. The fundamental clinical sign is the manifestation of an abnormal increase in heart rates of at least 40 bpm within 10 minutes assuming an upright position, delineating a condition of orthostatic intolerance and decreasing quality of life.Objective</str...

Neonatal Diabetes in Two Siblings with Foxp3 Variant

Colombi Carolina , Tornese Virginia , Pott Godoy Clara , Peña Sonia , De Franco Elisa , Guntsche Zelmira

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare disorder caused by loss-of-function mutations in the gene encoding the forkhead box P3 (FOXP3) transcription factor. This factor plays a key role in the differentiation and function of CD4+ CD25+ regulatory T cells, essential for the establishment and maintenance of natural tolerance.Objective: To describe clinic...

Tracking Body Mass Index From Infancy into Childhood

Beijsterveldt Inge van , de Fluiter Kirsten , Acton Dennis , Hokken-Koelega Anita

Background and Aims: It has been postulated that the first 3 months of life are critical for programming of adult metabolic health. We investigated if Body Mass Index (BMI) and Fat Mass percentage (FM%) in early life tracks to 5 years of age and if feeding mode influences tracking.Methods: In 268 term born, healthy infants from the Sophia Pluto cohort (161 boys ), BMI was determined at 3 and 6 months, 2 and 5 years o...

Determinants of the Peak GH Response of the Glucagon Stimulation Test in Slowly Growing Children

De Schepper Jean , Dewulf Charline , Craen Marghareta , Cools Martine , Gies Inge

Background/Aim: Currently, the minimum of the GH peak (pGH) to GH provocative stimuli, including the glucagon stimulation test (GST), has been arbitrary set in children at 7 µg/L, irrespective of gender and age. Several doses (fixed or per bodyweight) and ways of administration (IM or SC) of glucagon are being used in daily practice. This retrospective study explores the influence of gender, age, and adiposity on the pGH after a maximally effective glucag...
