Denosumab in the treatment of paediatric hypercalcaemia

Tischlinger Katharina , Blaschitz Alexandra , Hörtenhuber Thomas , Montero-Lopez Rodrigo , Wimleitner Marlene , Uday Suma , Crane Janet , Högler Wolfgang

Background: Hypercalcaemia has various etiologies and treatment is often challenging. Therapeutic options include aggressive fluid management, loop diuretics and antiresorptive drugs. Since both hypercalcaemia and bisphosphonates can cause acute kidney injury (AKI), bisphosphonates are not recommended in patients with renal impairment. Denosumab, an antiresorptive human monoclonal antibody, is not associated with AKI and offers a temporary treatment option. Ho...

Congenital Hyperinsulinism due to ABCC8/KCNJ11 mutations and the long-term outcome - a single center experience

Noordin Mazidah , Miyagi Hajime , Igarashi Mizuho , Kashima Takemoto , Fujioka Akiko , Ujita Nagisa , Yoshii Keisuke , Naiki Yasuhiro , Horikawa Reiko

Hyperinsulinism is a common cause of persistent hypoglycemia beyond infancy. Mutations in the ABCC8/KCNJ11 genes are the most common aetiology of congenital hyperinsulinism (CHI), leading to KATP channel mutation. This results in an inappropriate insulin secretion irrespective of hypoglycaemia. This is a cross-sectional study of the patients attending the paediatric endocrinology unit at the National Centre for Child Health & Development (NCCHD), Tokyo, Japan from March 20...

Grosse Martin , Abicht Angela , Gebhard Christian , Grasemann Corinna , Kiewert Cordula , Unger Nicole , Weber Frank , Bierkamp-Christophersen Dirk , J Kaiser Frank , Munteanu Martin

Carney complex 1 (CNC, OMIM# 160980) is an autosomal-dominantly inherited complex tumor predisposition syndrome associated with skin pigment abnormalities and neoplasms of heart, endocrine glands and other organs. CNC is caused by heterozygous constitutional loss-of-function variants in the PRKAR1A-gene. PRKAR1A codes for the cAMP-dependent protein kinase type I-alpha regulatory subunit, an enzyme that represents an integral part of protein kinase A (PKA) tha...

Clinical phenotyping of patients with genetic obesity

S. Welling Mila , Mohseni Mostafa , E.H. Meeusen Renate , R. Boon Mariëtte , J. de Groot Cornelis , M. van Haelst Mieke , A. Visser Jenny , L.T. van den Akker Erica , F.C. van Rossum Elisabeth

Introduction: In rare cases of obesity, genetic defects lead to hyperphagia and severe early-onset obesity. Genetic testing in patients with a suspected genetic obesity phenotype is important, as it can lead to patient-tailored treatment advice. For children, the Endocrine Society (ES) recommends genetic testing in children with early-onset of obesity (<5 years) and hyperphagia. It is unclear whether these recommendations can also be used in adult obesity c...

Clinical Characteristics and Long-Term Management for Patients with Vitamin D-dependent Rickets Type II: A Retrospective Study in Saudi Arabia

Binladen Amal , Alsagheir Afaf , Alhuthil Raghad

Background: Hereditary Vitamin D-Resistant Rickets (HVDRR) is a rare autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) resulting in end organ resistant to 1a,25-dihydroxyvitamin D, [1,25(OH)2D]. Majority of HVDRR has Elevated 1, 25(OH)2D which is a hallmark for diagnosis of this disease. High doses of vitamin D, oral calcium and most importantly IV calcium infusion are the mode of therapy in HVDRR.A...

FTO-mediated m6A modification of BDNF enhances GnRH expression during puberty onset via activating PI3K/AKT signaling.

Zang Shaolian , Yin Xiaoqin , Li Pin

Background: The etiology of central precocious puberty (CPP) still remains unknown. The abnormal expression of Fat mass and obesity-associated (FTO)-mediated N6-methyladenosine (m6A) has been confirmed to play the crucial roles in CPP. This study aimed to explore the mechanism of FTO-mediated m6A modification of brain-derived neurotrophic factor (BDNF) on CPP with puberty onset.Methods: The qRT-PCR and immunofluorescence...

Dysregulated adipose tissue expansion and impaired adipogenesis in Prader-Willi syndrome children before obesity-onset

Chao Yunqi , Zou Chaochun

Objective: Prader-Willi syndrome (PWS) is a rare genetic imprinting disorder resulting from the expression loss of genes on the paternally inherited chromosome 15q11-13. Early-onset life-thriving obesity represents the PWS clinical hallmarks. The noncoding RNA gene SNORD116 within the minimal PWS genetic lesion plays a critical role in the pathogenesis of the syndrome. Despite advancements in understanding the genetic basis for PWS, the pathophysiology of obes...

Low-Dose Liraglutide-Induced Acute Kidney Injury and Hepatocellular Disorder in an Adolescent Patient

Wittenberg Avigail , Komargodski Rinat , Rachmiel Marianna

Background: Liraglutide (SAXENDA®) is a glucagon-like peptide 1 (GLP-1) receptor agonist approved as an adjunct for chronic weight management in combination with a reduced-calorie diet and increased physical activity. Previous case reports have suggested an association between liraglutide use and acute kidney injury in adults, particularly at maintenance doses of 1.2 mg/day or higher. However, there is less data on the impact of liraglutide in the adolesce...

Introduction: Children with cancer are at increased risk of endocrine complications, especially children with a brain tumor. One of these late effects includes bone disorders (ranging from low bone mineral density (BMD) to osteoporosis). Children with a suprasellar Low Grade Glioma (LGG) may be especially at risk for bone problems due to exposure to multiple treatment modalities, hypothalamic dysfunction and/or decreased mobility in combination with vision los...

Differences of sex development (DSD) are congenital conditions with discordance between chromosomal, gonadal and/or anatomic sex. DSD can be syndromic or non-syndromic based on the presence or absence of somatic anomalies, respectively. Variants in several genes have been identified in association with errors of testis determination and male genital differentiation. However, despite technological advances, a genetic diagnosis is not achieved in nearly 50% of individuals presen...
