Thyroid Hormone Analog Therapy in Patients with MCT8 deficiency: the Triac Trial

Groeneweg Stefan , de Coo Rene , van Beynum Ingrid , van der Knoop Marieke , Aarsen Femke , de Rijke Yolanda , Peeters Robin , Visser Theo , Visser Edward

Introduction: Mutations in the thyroid hormone (TH) transporter MCT8 result in MCT8 deficiency, which is characterized by severe intellectual and motor disability and high serum T3 concentrations inducing thyrotoxicity in peripheral tissues. At present, no effective treatment is available, although preclinical studies suggest that the T3 analog Triac is a promising candidate to i) normalize serum T3 levels and thus alleviate the thyrotoxicosis and ii) restore TH signaling in t...

Background: Hypopituitarism is characterized by deficiency of one or more anterior pituitary hormones. POU1F1 mutations are the second most frequent known cause of combined pituitary hormone deficiency (CPHD). Patients are typically deficient in GH, TSH, and prolactin, although two unrelated cases were reported with isolated GH deficiency (IGHD). To date, all POU1F1 mutations have been reported for the predominantly expressed alpha isoform, which is a transcr...

Study of the Serum Kisspeptin Level in Healthy and Hypogonadotropic Boys

Nikitina Irina , Khoduleva Yulia , Nagornaya Irena , Vasileva Elena

Background: Kisspeptins, ligands of G protein-coupled receptor 54 (GPR54) encoded by the KiSS-1 gene, have recently emerged as key players of the gonadotropic axis. It was found that KiSS-1/GPR54 system plays an important role in the neuroendocrine control of gonadotropin secretion, brain sex differentiation, puberty onset and fertility. It is important to know if the kisspeptin serum level could be used as a diagnostic criterion to the stage of puberty or impairment of it in ...

Establishing Age, Sex, and Method Related Reference Ranges for Anogenital Distance - a Marker of In Utero Androgen Action

Ljubicic Marie Lindhardt , Thankamony Ajay , Acerini Carlo , Jensen Tina Kold , Main Katharina M , Petersen Jorgen Holm , Busch Alexander S , Upners Emmie , Hagen Casper P , Swan Shanna H , Juul Anders

Background: Anogenital distance (AGD) is an indicator of androgen action in utero. Reduced AGD has been found in males with hypospadias, cryptorchidism, low semen quality and infertility. Its usefulness as a clinical marker in patients with Disorders of Sex Development (DSD) is currently being investigated. However, detailed age, sex and method related reference ranges do not exist. Whether individual (body-size-adjusted) AGD is stable postnatally also remains to be e...

Topical Corticosteroid-Induced Adrenal Insufficiency

Ghaddhab Chiraz , Carine Beaufort

Introduction: Topical corticosteroids are often used for the treatment of dermatological diseases. However, systemic adrenal insufficiency may result from their overuse. Patients at risk for development of adrenal insufficiency include especially young children and patients with damaged skin barriers.Case presentation: We report the case of a 11-year-old boy who was seen in our clinic for suspicion of Cushing syndrome. He was adressed by a dermatologist ...

Favorable Outcome Despite Prolonged Hypoglycemic Episodes Following a Massive Insulin Overdose: A Case Series

Vollbach Heike , Gohlke Bettina , Schulte Sandra , Woelfle Joachim

Objective: To report on a pediatric case series of massive insulin overdose, its altered pharmacokinetics and the patients favorable outcome.Cases and results: Case 1: 300 IU of insulin aspart were subcutaneously injected into a non-diabetic eight-year-old boy within an extended suicide. After 16 hours he was found unconscious with generalized convulsions. The initial blood glucose concentration was below detection limit. It normalized o...

Interleukin-6 Levels are Associated with High Blood Pressure and Low HDL Cholesterol in Healthy 4-year-old Children

Jung Haewoon , Ah Lee Young , Lee Hye Jin , Lim Youn-Hee , Hong Yun-Chul , Shin Choong Ho , Yang Sei Won

Background: Interleukin-6 (IL-6) is a proinflammatory cytokine associated with obesity, insulin resistance, hypertension, and atherosclerosis in adulthood. Few studies have been conducted in healthy young children. We aimed to investigate whether IL-6 levels are associated with cardiometabolic risk factors in healthy 4-year-old children.Methods: From a prospective cohort study named Environment and Development of Children (EDC) cohort, a total of 421 sin...

Sex-related Differences and Effect of Puberty on Metabolic Syndrome in Obese Children and Adolescents

Guzzetti Chiara , Ibba Anastasia , Casula Letizia , Pilia Sabrina , Loche Sandro

Introduction: Metabolic syndrome (MS) is a known complication of obesity. It is still unclear whether gender and puberty influence the prevalence of MS in children and adolescents.Objective: Aim of the study was to evaluate the effect of gender and puberty on the prevalence of MS and on cardiovascular risk factors (CVRF) in obese children and adolescents.Patients and Methods: 1437 obese patients (age 9.7 (2.2–17.9) ys; 660 Mal...

Mutation in UCP2 Gene: A Rare Cause of Hyperinsulinemic Hypoglycaemia Syndrome in a Small-for-Gestational Age Newborn

Clemente Maria , Yesquen Pamela , Campos Ariadna , Mogas Eduard , Fernandez Monica , Yeste Diego

Hyperinsulinism is a common cause of severe and persistent hypoglycaemia during the neonatal period. Eleven genes have been identified that lead to unregulated insulin secretion and hyperinsulinemic hypoglycaemia (HH). Inactivating mutations in UCP2 gene have been described in a very small number of patients with HH. UCP2 protein is an inner mitochondrial carrier protein and its loss of function causes enhanced glucose oxidation and increased intracellular ATP synthes...

Neonatal Hyper- and Hypoglycaemia; Widening the Clinical Phenotype of Transient Neonatal Diabetes Mellitus due to 6q24 Methylation Defects

Taylor-Miller Tashunka , O'Connell Michele , Sabin Matthew

6q24 methylation defects are the most common cause of Transient Neonatal Diabetes Mellitus (TNDM). The clinical picture is one of impaired insulin secretion, small for gestational age and diabetes mellitus aged <6 months. This case illustrates the fluctuation between both hyper- and hypoglycaemia that can been seen in 6q24 methylation defects. A term, small for gestational age baby boy was noted to have hypoglycaemia (BSL 1.8 mmol/l) at 1.5 h of life which resolved with or...
