CRN04777, an oral, nonpeptide selective SST5 receptor agonist, dose-dependently suppresses both fasting and stimulated insulin secretion: results from a first in human study

Ferrara-Cook Christine , Luo Rosa , De la Torre Eduardo , Wang Yang , Betz Stephen , Lagast Hjalmar , Struthers Scott , Hovelmann Ultike , Heise Tim , Krasner Alan

Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia in neonates, infants, and children, and is caused by genetic mutations in pancreatic beta-cells. Current therapies are burdensome, have limited efficacy, and are associated with significant morbidity. CRN04777 is a potent, orally-bioavailable, selective SST5 agonist that suppresses insulin secretion in the terminal steps of the insulin secretion pathway and could be useful for patients with con...

Sulphonylurea for Improving Neurological Features in Neonatal Diabetes: a systematic review and meta-analyses

de Gouveia Buff Passone Caroline , Giani Elisa , Vaivre-Douret Laurence , Karayawasam Dulandjalee , Berdugo Marianne , Garcin Laure , Beltrand Jacques , Marques Bernardo Wanderley , Polak Michel

Background: In monogenic diabetes due to KCNJ11 and ABCC8 mutations that impair KATP- channel function, sulphonylureas improve long-term glycaemic control. Although KATP channels are extensively expressed in the brain, the effect of sulphonylureas on neurological function has varied widely. We evaluated published evidence about potential effects of sulphonylureas on neurological features, especially epilepsy, cognition, motor function and muscular tone, visuo-...

Siklar Zeynep , De Franco Elisa , FlanagaN Sarah , Ellard Sian , Ceylaner Serdar , Boztug Kaan , Dogu Figen , Ikinciogullari Aydan , Kuloglu Zarife , Kansu Aydan , Berberoglu Merih

Background: Monogenic diabetes represents a group of disorders resulting from a single gene defect leading to disruption of insulin secretion or a reduction in the number of beta cells. Despite the classification of monogenic diabetes according to age of onset, with neonatal DM (<6 months of age) and maturity onset diabetes of young (MODY) (>6 months and <25 years of age); not every case can be classified into those groups.Objective and hypot...

IPEX Syndrome Caused by A Novel Mutation in Foxp3 Gene: A Case Report

Bich Ngoc Can Thi , Chi Dung Vu , Phuong Thao Bui , Ngoc Khanh Nguyen , Thanh Mai Do Thi , Johnson Matthew , De Franco Elisa , Ellard Sian

Background: Immune dysregulation, polyendocrinopathy, enteropathy, X-linked (IPEX) syndrome is a rare and life-threatening primary immunodeficiency characterized by widespread autoimmunity. Mutations in the FOXP3 gene have been identified as the cause for IPEX syndrome.Objective and hypotheses: To describe clinical characteristics and genetic finding in the first Vietnamese patient with mutation of FOXP3 gene.Meth...

Plasma Humanin Levels During Normal Childhood and Puberty. Study of Possible Correlations with Sex, Age, and Insulin Levels

Dona Valeria De , Ciaccio Marta , Wan Junxiang , Guercio Gabriela , Vaiani Elisa , Krochik Gabriela , Maceiras Mercedes , Lazzati Juan Manuel , Rivarola Marco , Cohen Pinchas , Belgorosky Alicia

Background: Humanin is a novel signaling peptide which has been showed, by in vitro and in vivo studies, to improve insulin sensitivity. As plasma humanin levels decrease during adulthood, particularly during aging, it has been proposed that the increment of insulin resistance in aging might be associated with lesser humanin plasma values.Objective and hypotheses: The physiological insulin resistance observed during puberty in normal ch...

Vitamin D Status in Romanian Children 0–18 Years – Should we be More Careful Regarding Supplementation?

Chirita-Emandi Adela , Puiu Maria

Background: In Romania (latitude 48°15’N to 43°40’N), vitamin D supplementation is a common practice mostly in 0–2 year old infants. No published information is available regarding vitamin D status in Romanian children.Objective and hypotheses: We aimed to evaluate the seasonal and age variation of vitamin D status in a large Romanian pediatric patient population.Method: 1 395 individuals, 0–18years, f...

Reduced Humanin Levels in Children with Type 1 Diabetes Mellitus

Hernandez Maria Isabel , Wan Junxiang , Valdes Carolina , Avila Alejandra , Codner Ethel , Cohen Pinchas

Background: Recent studies in multiple models of type 1 diabetes mellitus (T1DM) have demonstrated the role of mitochondrial abnormalities in the pathogenesis of this disease and its complications. Humanin is a potent cyto-protective and ‘metaboloprotective’ molecule in vitro and in vivo, including the protection of β cells from apoptosis, improvements in insulin secretion and action, and both prevention and treatment of diabetes in the NOD mou...

The effect of a GnRH analogue injection on the circulating levels of kisspeptin-1 in girls with suspected central precocious puberty

Rodanaki Maria , Rask Eva , Lodefalk Maria

Introduction: Kisspeptin stimulates the gonadotropin releasing hormone (GnRH) neurons in hypothalamus initiating puberty. However, it is not known whether GnRH inhibits kisspeptin secretion by negative feedback and whether there are any associations between circulating levels of kisspeptin and other hormones, like ghrelin, important for the onset of puberty.Methods: Thirteen girls with suspected central precocious pubert...

Background: Achondroplasia (ACH), the most common short-limbed skeletal dysplasia, is characterized by impaired endochondral ossification resulting from gain-of-function pathogenic variants in the fibroblast growth factor receptor 3 (FGFR3) gene, a negative regulator of endochondral bone growth. People with ACH are at risk for several significant co-morbidities, including brainstem compression due to foramen magnum stenosis, sleep-disordered breathing, chronic...
