Evaluation of Diabetes Related Complications and Endothelial Dysfunction in Adolescents with Type 1 Diabetes

Metwally Nehad , Macken Alan , O'Regan Myra , Fitzgerald Helen , McDonnell Ciara , O'Gorman Clodagh S , Molloy Eleanor , Roche Edna F

Introduction: Patients with type 1 diabetes (T1D) are at high risk of developing vascular complications. Endothelial dysfunction is considered the early reversible stage in the development of diabetes related vascular disease. Early detection and management of endothelial dysfunction can delay or even prevent the development of vascular complications.Aim: Endothelial dysfunction is associated with poor metabolic control in adolescents with T1D. Based on ...

Pubertal Onset in Boys is Influenced by BMI and Genetic Variation of Fshb and Fshr: A Study in Two Population-Based Cohorts of Different Genetic Ancestry

Busch Alexander S. , Hagen Casper P. , Main Katharina M. , Almstrup Kristian , Pereira Anita , Corvalan Camila , Mericq Veronica , Juul Anders

Background: Age at onset of puberty exhibits a remarkable variation mirroring nutritional, environmental, socioeconomic and genetic factors. While large genome-wide association studies identified more than hundred genetic loci associated with age at menarche in girls, knowledge on loci associated with age at pubertal onset in boys is sparse. FSHB/FSHR genetic variants have been shown to affect pubertal timing in girls and reproductive parameters in men.<p class="a...

Cardiac Function in Pediatric Patients with Congenital Adrenal Hyperplasia

Mooij Christiaan F. , Pourier Milanthy S. , Weijers Gert , de Korte Chris L. , Claahsen - van der Grinten Hedi L. , Kapusta Livia

Background: Congenital adrenal hyperplasia (CAH) is characterized by cortisol deficiency and hyperandrogenism. Both hyperandrogenism and treatment with supraphysiological doses of glucocorticoids may cause unfavorable changes in the cardiovascular risk profile of CAH patients. Data on the cardiac function in CAH patients is scarce.Objective and hypotheses: To evaluate the cardiac function in pediatric CAH patients.Method: The cardi...

Two French Families with Vitamin D Dependency Rickets Type 1B Harbor Homozygous Recessive Expression Of CYP2R1 Mutations L99P and G42_L46DEL INSR

Molin Arnaud , Feillet Francois , Demers Nick , Wiedemann Arnaud , Brennan S , Kaufmann Martin , Jones Glenville , Kottler Marie Laure

Vitamin D dependency rickets type 1B (VDDR-1B) is a rare condition classified as rickets due to inadequate 25-hydroxylation of vitamin D. In this study, we describe rickets and loss-of-function CYP2R1 mutations in 6/10 individuals tested from two unrelated families. Five patients in family 1 (F1) have homozygous L99P mutations; while one member of family 2 (F2) has novel homozygous mutations at G42_L46del insR. The mutations, as well as another variant M248I found in ...

Fractures in Children with Type 1 Diabetes are Associated with Poorer Bone Mineral Status and Glycaemic Control

Chen Suet Ching , Shepherd Sheila , McMillan Martin , McNeilly Jane D , Robertson Kenneth J , Wong Sze Choong , Ahmed S Faisal

Background: Type 1 Diabetes (T1D) is associated with increased fracture risk.Aim: Understand the association between glycaemic control and bone health in children with T1D.Method: Children (n, 32) with T1D and a median (range) age of 13.7 years (10.4,16.4), were recruited to study bone mineral content (TB & LS) and body composition by DXA. All data were corrected for size. Vitamin D, Bone alkaline phosphatase (BAP) and...

Risk factors for Atherosclerosis after Anticancer Treatment in Childhood: The Assessment of Lipid Parameters and Indicators of Susceptibility to Atherosclerosis in a Group of Pediatric Patients after Anticancer Treatment

Połubok Joanna , Jasielska Olimpia , Gonera Aleksandra , Kozicka Marta , Sęga-Pondel Dorota , Kazanowska Bernarda , Barg Barg

Introduction: Lipid disorders are a common complication of anticancer therapy. These disorders may be included in both the metabolic syndrome or also may be associated with increased risk of cardiovascular disease. The aim of our study is to evaluate lipid profile in children after anticancer treatment.Materials and methods: Study group consisted of 44 patients (aged 3.25–16 years) with solid tumors, at least one year after cessation of anticancer t...

Case Report on Hyperinsulinism/hyperammonaemia Syndrome: An Easily Treatable Cause of Postprandial Hypoglycaemia

Seneviratne Sumudu , Jayatunge Tharanga , Atapattu Navoda , De Silva K. S. H. , Wickramasinghe V. P. , De Silva Harendra

Background: Hyperinsulinism/hyperammonaemia (HI/HA) syndrome is associated with postprandial hypoglycaemia and mild hyperammonemia. There is increased insulin release following protein ingestion, which is amenable to diaxozide therapy. While developmental delay and normoglycaemic seizures can also occur, hepatomegaly has not been reported. We report a child with HI/HA and hepatomegaly, mild learning difficulty and obesity, who was initially mistaken to have glycogen storage di...

Pseudohypoaldosteronism Type 1: Role of Urinary Steroid Profiling in Specific and Early Diagnosis: Lessons in Differential Diagnosis of PHA1 vs PHA2 (Renal Tract Anomaly)

Abbot V , Ghataore L , Pieterse D J , Chapman S , Kapoor R R , Taylor N F , Buchanan C R

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...
