Background: H syndrome (OMIM #602783) is an autosomal recessive syndrome resulted from mutations in the SLC29A3 gene, encoding hENT3 protein. Characteristic findings are cutaneous hyperpigmentation, hypertrichosis, hepatosplenomegaly, hypogonadism, hyperglycemia/diabetes mellitus, cardiac anomalies, hallux valgus and short stature. Herein we report a girl with multiple endocrinopathies due to H syndrome.Case: Ten year and 5 month old girl was referred be...

Inorganic phosphate is essential for bone stability and various cellular metabolic pathways. Serum phosphate levels are regulated by an endocrine triangle of calcitriol, parathyroid hormone and fibroblast growth factor 23. In addition, a mineral buffering system is required to prevent mineral stress and ectopic calcification by spontaneous precipitation of calcium and phosphate. Current research indicates a complex interplay of phosphate homeostasis and inflammatory processes,...

Background: IGF1 is a biomarker of GH, and is often used to titrate the dose of GH therapy. However, IGF1 production is regulated by not only GH but also other factors.Objective and hypotheses: We investigated whether the increase in IGF1 at several time points after the commencement of GH therapy could be a predictive factor for the improved growth.Method: We studied 45 pre-pubertal patients with GH deficiency (GHD) that had conti...

Background: Few studies have described the phenotypic spectrum of Septo-Optic Dysplasia (SOD). The aim of this study was to evaluate the range of H-P structural abnormalities and the endocrine morbidity of children with SOD and related disorders.Methods: Retrospective longitudinal single centre study of children with SOD (n:171), Multiple Pituitary Hormone Deficiency (MPHD) (n:53) and Optic Nerve Hypoplasia (ONH) (n:35).<p class="ab...

Background/Objective: 17bHSD3D is a rare genetic disorder that leads to disorders of sex development (DSD) in 46,XY patients. Phenotype at birth ranges from unsuspicious female genitalia to micropenises. Besides molecular genetic testing no reliable lab parameters have been established for pre-identifying patients through basal steroid-levels or hCG-testing. This bares the risk of under-, mis- or late diagnosis. Further, little research has been performed on psychological well...

Background: Obese adults with normal glucose tolerance (NGT) but 1-h post load glucose (1 hPG)≧155 mg/dl have an increased cardiometabolic risk. In children, preliminary data suggest that 1hPG≧132.5 mg/dl might identify those at higher risk of type 2 diabetes.Objective and hypotheses: To assess whether NGT obese youth with 1hPG ≧132.5 mg/dl (High-NGT) have worse insulin sensitivity and secretion compared to obese youth with 1hPG &#60...

Introduction: Adolescents are considered the main consumer group of Energy Drinks (EDs). EDs are associated with adverse cardiovascular events, such as severe cardiac arrhythmia or arterial hypertension. Recent studies of our department revealed a significantly increased brachial blood pressure and arterial stiffness after the acute ED consumption in healthy adolescents. Increased central blood pressure is linked with the onset of end-organ damages such as lef...

Duplications of the dosage sensitive sex locus Xp21.2 have been associated with 46,XY gonadal dysgenesis (GD) for nearly 25 years. In the past, duplications have always included the NR0B1 (nuclear receptor subfamily 0 group B, member 1, also known as DAX1) gene, a known antagonist of SF1 (Steroidogenic Factor 1) dependent SOX9 (SRY Box 9) activation and the GD was attributed to its "double gene dose". However, recent findings have questioned the neces...

Background: Childhood obesity increases the risk for adult obesity and cardio metabolic disease.Objective and hypotheses: The aim with the present study was to investigate longitudinal changes of childhood body mass index (BMI), overweight, and obesity in boys born 1946 until present time, using the population-based BMI Epidemiology STudy (BEST) cohort in Gothenburg, Sweden.Method: We collected detailed growth data (height and weig...

Background: Bi-allelic mutations of CYP21A2 encoding 21-hydroxylase are the most frequent cause of congenital adrenal hyperplasia (CAH). Non-classical CAH (NCCAH) or even just hyperandrogenism may be caused by mild or mono-allelic (single) heterozygous mutations of CYP21A2. These mutations are associated either with elevated basal or ACTH-stimulated levels of 17-hydroxyprogesterone (17OHP) in blood.Objective and hypotheses: The objective of this study wa...
