Peripheral and Hypothalamic Alterations in the Insulin-like Growth Factor (IGF) System in Response to High Fat Diet-induced Weight Gain

Guerra-Cantera Santiago , Díaz Francisca , Ros Purificación , Freire-Regatillo Alejandra , Torrecilla-Parra Marta , Barrios Vicente , Frago Laura , Chowen Julie A. , Argente Jesús

The insulin-like growth factor (IGF) system is fundamental for physiological processes such as growth and metabolism. In addition, in the brain it regulates glucose metabolism and neuroprotection. The IGF axis can be altered by nutritional status, but little is known regarding the effects of specific dietary components on this system.Our aim was to examine how high-fat diet (HFD) and low-fat/high sucrose diet (LFHSD) intake affect the central and circula...

The association between Epilepsy and Diabetes mellitus diagnosed before 2 years of age

Abdelmeguid Yasmine , Mowafy Ehsan , Marzouk Iman , Elsayed Shaymaa

Introduction: Epilepsy or seizures are often observed in patients with diabetes mellitus (DM). Different types of seizures occur in approximately 25% of patients with DM. The exact cause remains undetermined. Moreover, a possible association between T1DM and epilepsy exists. Risk factors for epilepsy in T1DM include younger age at onset, recurrent hypoglycemia or DKA, and poor glycemic control.Aim of the work: The aim of...

Transient TSH Elevation in Infants Referred on Newborn Screening – Features, Prevalence and Trends

Ouarezki Yasmine , Jones Jeremy , Fitch Moira , Shaikh Guftar , Donaldson Malcolm

Background: Up to 20% of infants referred on newborn congenital hypothyroidism (CH) screening are subsequently shown to have transient TSH elevation rather than permanent CH. Correct identification of such cases is important to avoid prolonged treatment with thyroxine and unnecessary clinic attendance.Objective: To determine the prevalence, trends and profile of infants with transient TSH elevation referred between August 1979 and December 2015 by the Sc...

Age at Diagnosis and Mental Development in Children with Congenital Hypothyroidism in the Absence of Newborn Screening Programme

Ouarezki Yasmine , Ladjouze Asmahane , Kherra Sakina , Djermane Adel , Laraba Abdennour

Background: The outcome of congenital hypothyroidism (CH) has dramatically changed since the start of neonatal screening. However the benefit of this program is not felt in Algeria and other countries where the pathology is still causing irreparable brain damage.Objective and hypotheses: To evaluate age at diagnosis of CH and its impact on the mental development in the absence of new-born screening.Method: Case notes of all patient...

The challenges faced in the management of Congenital Generalized Lipodystrophy.

Abdelmeguid Yasmine , Elashry Reham , Elsayed Shaymaa , Raafat Shaymaa ,

Background: Congenital Generalized Lipodystrophy (CGL) is a rare autosomal recessive disease. The prevalence has been reported to be 1 in 10million with around 500 cases worldwide. The absence of functional adipocytes results in storage of lipids in other tissues, including muscle & liver. The diagnosis of CGL is based on clinical data; however, there is phenotypic heterogeneity. Metreleptin injections cause decreased appetite & is beneficial in loweri...

Celiac disease in a patient with Sclerosteosis: an association or just a co-incidence?

Abdelmeguid Yasmine , Riad Salma , Mokhtar Nada , Taha El-Hendawy Mahmoud

Sclerosteosis is a rare autosomal recessive disorder characterized by progressive skeletal overgrowth and increased bone density. Loss of function mutations of SOST gene, coding for sclerostin, are linked to sclerosteosis. Sclerostin plays a critical role inhibiting osteoblastic activity and preventing excessive bone formation by antagonizing the Wnt signaling pathway. Sclerosteosis patients are often tall and have excessive body weight due to high skeletal weight. To...

Severe clinical presentation of congenital hyperinsulinism due to newly discovered mutation of HK1: case report

Tumasyan Dalar , Hopkins Jasmin , Flanagan Sarah , Ashotyan Azatuhi , Navasardyan Lusine

Introduction: Congenital hyperinsulinism (CHI) is a disorder of pancreatic beta-cells characterized by inappropriate secretion of insulin leading to hyperinsulinemic hypoglycemia. Insulin secretion is a complex, genetically regulated process. Mutations in several genes known to regulate insulin secretion result in CHI. Recently, non-coding mutations in HK1, which cause the aberrant expression of hexokinase 1 (HK1) in beta cells, have been reported as a novel c...

Correlation Between Genotype and Phenotype Characteristics in Children with Congenital Hyperinsulinism (CHI) in a Specialist Centre

Bosch Laura , Kallefullah Mohammad Jasmina , Dastamani Antonia , Gilbert Clare , Morgan Kate , Houghton Jayne , Ellard Sian , Flanagan Sarah , Shah Pratik

Introduction and Aim: Congenital hyperinsulinism (CHI) is the most common cause of hypoglycaemia in early infancy and represents a heterogeneous disorder with respect to clinical presentation, histology and genetics. The aim of our study is to review correlation between genotype and phenotypic characteristics of children with CHI.Methods: Retrospective review of CHI patients with positive genetics during the last 8 years...

Hepatic NAD Metabolism is Dysregulated by an Excessive Supply of Lipids

Kiess Wieland , Penke Melanie , Treebak Jonas T , Schuster Susanne , Gorski Theresa , Garten Antje

Background: Animal and human studies have shown that nicotinamide phosphoribosyltransferase (NAMPT), the key enzyme of mammalian NAD biosynthesis from nicotinamide, is modified in non-alcoholic fatty liver disease. Here, we investigated the effect of a high fat diet on hepatic NAD metabolism in mice.Objective and hypotheses: A dysregulation of NAD metabolism is a pathogenic factor for the development of steatohepatitis (NASH).Metho...

NEUROD1 mutation as a cause of neonatal diabetes: the rarest of the rare!

Abdelmeguid Yasmine , Elwan Samar , De Franco Elisa , Abd Elmaksoud Marwa , Khater Doaa

Background: NEUROD1 encoding neurogenic differentiation 1 is known to play an important role in the development of the pancreas and central nervous system. Heterozygous mutations have been rarely identified as a cause of maturity-onset diabetes of the young (MODY6). Biallelic NEUROD1 mutations have been reported to cause neonatal diabetes mellitus (NDM) as well. However, only 3 cases have been reported worldwide so far....
