Lebl Jan , Toni Ledjona , Plachy Lukas , Kucerova Petra , Elblova Lenka , Sumnik Zdenek , Kolouskova Stanislava , Snajderova Marta , Obermannova Barbora , Pruhova Stepanka

Background: SGA-SS, defined as birth weight and/or birth length below -2SD for gestational age and postnatal statural height below -2.5SD according to age- and sex-specific standards, is a heterogeneous condition reflexing exogenous (maternal, placental) or endogenous (foetal) inadequacies. Within the past two decades, a handful of genetic causes of SGA-SS have been elucidated. However, how each genetic aetiology impacts individual GH treatment outcomes awaits...

Deciphering Genetic Aetiology Among Children Born Small-For-Gestational-Age with Persistent Short Stature (SGA-SS): Phenotypic Characteristics at Diagnosis in a Large Single-Centre Cohort

Toni Ledjona , Plachy Lukas , Kucerova Petra , Elblova Lenka , Sumnik Zdenek , Kolouskova Stanislava , Snajderova Marta , Obermannova Barbora , Pruhova Stepanka , Lebl Jan

Background: SGA-SS is a heterogeneous condition defined as birth weight and/or birth length below -2SD for gestational age and postnatal height below -2.5SD, according to age-and sex-specific normative values. Despite being an indication for growth hormone (GH) therapy for 15 years, aetiology and prediction of treatment outcomes in most of SGA-SS children awaits elucidation.Aim: To decipher genetic aetiologies among a la...

A Case of Hutchinson-Gilford Progeria Syndrome (HGPS) due to a Pathogenic LMNA Variant c.433G>A (p.Glu145Lys): Growth Hormone Administration Failed to Improve Growth and Long-term Outcome

Toni Ledjona , Dušatkoa Petra , Novotna Dana , Zemkova Dana , PrUhova Štěpanka , Lebl Jan

Hutchinson-Gilford Progeria Syndrome (HGPS) is an extremely rare condition (estimated incidence 1:4–8 million), caused by mutations in LMNA gene, which leads to premature aging. Median life expectancy is shortened to 13 years due to vascular complications such as stroke or myocardial infarction. We present below the history of a child born with a pathogenic LMNA variant c.433G>A (p.Glu145Lys). A male patient was referred due to failure to thrive and low growth velocit...

The genetic landscape of children born small for gestational age with persistent short stature

Toni Ledjona , Plachy Lukas , Dusatkova Petra , Anne Amaratunga Shenali , Elblova Lenka , Sumnik Zdenek , Kolouskova Stanislava , Snajderova Marta , Obermannova Barbora , Pruhova Stepanka , Lebl Jan

Background: Approximately 10% of children born small for gestational age (SGA) fail to catch-up nd remain short (SGA-SS). Although several mechanisms causing SGA-SS have been elucidated, the primary cause remains speculative in most cases.Aim: To decipher genetic causes of SGA-SS defined as birth length and/or birth weight <-2 SD for gestational age, and body height <-2.5 SD after the 3rd year of life within a larg...

High rate of positive genetic findings in children born small for gestational age with persistent short stature (SGA-SS): Growth plate genes as key regulators of intrauterine growth

Toni Ledjona , Plachy Lukas , Dusatkova Petra , Anne Amaratunga Shenali , Kolouskova Stanislava , Obermannova Barbora , Snajderova Marta , Sumnik Zdenek , Pruhova Stepanka , Lebl Jan ,

Background: Ten percent of children born small for gestational age fail to catch-up and remain short during childhood (SGA-SS). Several genes causing SGA-SS have been described, however, in most cases, the mechanisms of prenatal and postnatal growth impairment remain unknown.Aim: To decipher genetic etiologies within a large single-center cohort of SGA-SS children in order to better understand the pathophysiological mech...

Panhypopituitarism after treatment procedures in pituitary-hypothalamic area – a single center experience

Bazdarska Yuliya , Iotova Violeta , Galcheva Sonya , Halvadzhiyan Irina , Yordanova Nikolinka , Kondev Toni , Enchev Yavor ,

Background: The most common conditions requiring surgery or radiation therapy of the sella and suprasellar area in childhood are craniopharygiomas and pituitary adenomas. Therapeutic procedures involving pituitary gland often lead to multiple hormonal deficiencies, and experienced multidisciplinary team following guidelines and applying systematic approach could improve outcomes.Aim: To evaluate hormonal replacement ther...

Background: Data regarding epidemiology and management of Diabetic Ketoacidosis (DKA) in Italian children with T1D at disease onset are lacking.Method: From 1/1/2012 to 31/12/2013 a survey on DKA was conducted in all paediatric Centres belonging to the Italian Society for Pediatric Diabetology and Endocrinology. DKA was defined according to the ISPAD criteria. The following data were collected: treatment according ISPAD protocol yes or not, type of rehyd...

Background: Type 1 diabetes (T1D) is the most frequent etiology in Italian diabetic children and adolescents. Data on type 2 (T2D) and monogenic diabetes (MD) prevalence are scanty.Objective and hypotheses: To estimate the prevalence of T1D, T2D, secondary diabetes, and MD in a pediatric population of Italian diabetic patients.Method: Data on 3,076 patients (diabetes onset January 2007–December 2012, age at diagnosis <18 y...
