Autosomal Dominant Growth Hormone Deficiency due to a Novel c.178G>A Mutation in the GH1 Gene Causing Instability of the Mutant GH Protein (p.Ala34Thr)

Miller Bradley , Tan Jimmy , Parween Shaheena , Eble Andree , Ternand Christine , Gregory Louise , Dattani Mehul , Pandey Amit

Background: The most frequent cause of familial growth hormone deficiency (GHD) is Type II autosomal dominant GHD (isolated GHD type II) due to several heterozygous GH1 mutations.Method: Genomic DNA from patients with familial GHD was enriched for the coding exons using hybrid capture technology and GH1 was sequenced using Next Generation Sequencing technology. Plasmids containing genes for WT and A34T GH1 were transfected into NCI HEK2...

Novel Genetic Variants in a Cohort of Paediatric and Adolescent Patients with Hypogonadotrophic Hypogonadism and Kallmann Syndrome

Gregory Louise , McCabe Mark , Bancalari Rodrigo , Tziaferi Vaya , Spoudeas Helen , Dattani Mehul

Background: Hypogonadotrophic hypogonadism (HH) is a complex developmental disorder characterized by a reduction in gonadotrophins (LH, FSH) released from the anterior pituitary. LH and FSH stimulate the ovaries or testes to release sex hormones that cause the onset of puberty, therefore delay in onset or complete absence of puberty is seen in the phenotype, often accompanied by short stature and genital abnormalities. When anosmia accompanies HH in the phenotype it is termed ...

The effect of lifestyle intervention on glycaemic variation, quality of life and satiety levels in children and young people with obesity

Apperley Louise , Senniappan Senthil

Introduction: Childhood obesity is associated with pre-diabetes and type 2 diabetes mellitus. The gold standard investigation for these is an oral glucose tolerance test (OGTT). The aim of our study is to investigate glycaemic dysregulation in children and young people (CYP) with obesity using continuous glucose monitoring (CGM) and evaluate the effect of intense lifestyle intervention on various complications.Methods: 3...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...

Case Series; Central Diabetes Insipidus Presenting to a District General Hospital

Keelty Gemma , Weerasinghe Kamal , Gregory John

Background: In a paediatric setting polydipsia can be a commonly reported symptom which is usually innocent and habitual in nature. Diabetes Insipidus is a rare cause of pathological polydipsia. A high index of suspicion must be used in patients who exhibit other symptoms alongside polydipsia and investigations considered.Case presentation: We present three patients who have presented to a district general hospital within a short period of time with subs...

The MAPK Effector BRAF is Essential for the Integrity of Hypothalamic-Pituitary Development and Deregulation of this Pathway Causes Congenital Hypopituitarism

Gregory Louise , Kypranou Nikolina , Besser Rachel , Vignola Lilliana , Temple Karen , Davis Justin , Gevers Evelien , Dattani Mehul , Gaston-Massuet Carles

Background: BRAF is a component of the RAS/MAPK signalling pathway; germline mutations in components of this pathway are associated with congenital abnormalities such as Cardio-Facio-Cutaneous (CFC), Noonan and Costello Syndromes. These syndromes, known as RASopathies, are characterised by variably penetrant central nervous system, cardiac and facial abnormalities. Importantly, short stature and delayed puberty have been associated with these syndromes, as have featur...

Differences Between Short- and Long-term Outcomes of Laparoscopic Sleeve Gastrectomy in Adolescence

Ybarra Marina , Rocha Franco Ruth , Santos Tiago Jerônimo dos , Rachid Ludmilla , Bezerra Marilia P. C. , Cominato Louise , Damiani Durval , Prieto Velhote Manoel Carlos

Background: Laparoscopic sleeve gastrectomy (LSG) has been established as a safe and effective bariatric procedure during adolescence, but its long-term results remain uncertain. Our aim was to report and compare the short- and long-term outcomes of LSG in adolescents.Methods: We performed a retrospective analysis of patients submitted to LSG between 2010 and 2013 in our Institution. Baseline, short-term (1 year) and lon...

Clinical and Neuroradiological Characteristics in Children and Adolescents with Septo-Optic Dysplasia, Multiple Pituitary Hormone Deficiencies and Optic Nerve Hypoplasia: Experience from a Single Tertiary Centre

Guemes Maria , Cerbone Manuela , Bagkeris Manolis , Gregory L C , Kasia Tessa , Dattani Mehul

Background: Septo-optic dysplasia (SOD) is an important cause of hypopituitarism, although less common than multiple pituitary hormone deficiency (MPHD). Children with optic nerve hypoplasia (ONH) are at risk of hormone and neurocognitive disturbances.Objective and Hypotheses: We describe clinical and neuroradiological findings of these three overlapping conditions, aiming to understand their pathophysiology.Method: Retrospective a...

Residual C-Peptide in Paediatric Patients with Type 1 Diabetes

Martin-Frias Maria , Oyakawa Yoko P , Alonso Milagros , Roldan Belen , Alvarez M Angeles , Barrio Raquel

Background: Preservation of C-peptide is important and has become regarded a relevant endpoint as already a quite small residual C-peptide seems to be related to both less acute and late diabetes complications.Objective: To assess the residual C-peptide secretion in pediatric patient with T1D.Method: Cross-sectional study of 157 patients with T1D. We analyzed: age at diagnosis, age at time of study (years), sex, diabetes duration (...

A Novel Minor Spliceosome Defect Associated with Growth Hormone Deficiency (GHD) and Primary Ovarian Insufficiency (POI)

Akin Leyla , Gregory Louise , Buonocore Federica , Group GOSgene , Kurtoglu Selim , Kendirci Mustafa , Burçin Gonen Z. , Lovell-Badge Robin , Rizzoti Karine , Dattani Mehul

Objectives: We describe 5 pedigrees with a novel phenotype including GHD associated with primary ovarian insufficiency (POI) and investigate the underlying molecular basis.Patients and Methods: 6 Turkish patients (5F, 1M) born to 5 consanguineous pedigrees with severe GHD were identified. All females had POI; the male had normal puberty. All had severe postnatal growth retardation (height -4.4 to -8.9 SDS at presentation...
