Background: Ovarian Dysgenesis (OD) is a rare genetically heterogeneous XX Disorder of Sex Development. It presents clinically with primary amenorrhea, hypergonadotrophic hypogonadism and infertility. The genetic basis of OD remains unknown in 70% of cases. To identify novel genetic causes of OD, we are investigating families with one or more patients diagnosed with OD.Methods: Using a patient-based approach, WES was per...

Down syndrome (DS) is characterized by a higher incidence of congenital hypothyroidism (CH) and a high prevalence of subclinical hypothyroidism (SH) early in life. Children and adults with DS have an increased risk of developing autoimmune thyroid disease, however CH and early SH cannot be explained by thyroid autoimmunity. The etiology of CH and early SH in DS remains to be elucidated. Considering the recently discovered genome-wide transcriptional and epigenetic alterations ...

Results from a Global, Multi-Center, Phase 2b Study (RIZE) in Congenital Hyperinsulinism: Characterization of a High Unmet Treatment Need and Glycemic Response to RZ358

Background: Congenital Hyperinsulinism (CHI) is the most frequent cause of severe, persistent hypoglycemia in children. Persistent hypoglycemia places patients at risk for adverse clinical outcomes, and current guidelines recommend maintaining plasma glucose >3.9mmol/l. CHI patients often have substantial, residual hypoglycemia and fail to meet treatment goals with currently available standard of care (SOC) therapies. In this study, we aimed to characterize...

Dasiglucagon Treatment Over 21 days in Infants with Congenital Hyperinsulinism Results in Glycaemic Stability and Reduces Requirement for Intravenous Glucose

Background: Congenital hyperinsulinism (CHI) is a chronic and complex rare endocrinopathy with dysregulated insulin secretion causing severe and recurrent hypoglycemia resulting in adverse neurologic and developmental sequelae in children. Current treatment options are limited and often inadequate to treat CHI. Dasiglucagon (DASI), a glucagon analog administered by subcutaneous continuous infusion, has demonstrated reduction in glucose infusion rate (GIR) in P...

The effect of timing of puberty suppression on breast development in trans girls; a cross-sectional study

Context: For transgender women undergoing gender-affirming hormone therapy (HT), breast development is an important treatment outcome. Since earlier studies showed small breast volumes in trans women treated with HT, we hypothesized that testosterone exposure during puberty might negatively influence breast development and that early initiation of puberty suppression (PS) might have a positive effect on breast development.Aim:</s...

Introduction: Congenital adrenal hyperplasia is the most common cause of primary adrenal insufficiency. It is a rare monogenic recessive disorder. In African setting in absence of neonatal screening, the diagnosis is still late, based on a clinical approach. During this clinical enquiry, information form past history or pedigree of the patient are of a huge importance and may revealed surprisesPatients and methods: In th...

Biphasic Glucocorticoid Rhythm in One Month Old Infants: Reflection of a Developing HPA-Axis?

Hollanders Jonneke J. , de Goede Paul , van der Voorn Bibian , Honig Adriaan , Rotteveel Joost , Dolman Koert , Kalsbeek Andries , Finken Martijn J.J.

Background: The hypothalamus-pituitary-adrenal (HPA) axis displays a diurnal rhythm, peaking in the morning and with a nadir at night. However, not much is known about the development of the HPA- axis, although strikingly some evidence suggests that a rhythm with a peak in the afternoon is already present antenatally. We aimed to describe HPA-axis activity at age 1 month as well as study possible influencing factors.Methods</stro...

Two-year Outcomes of Whanau Pakari: A Novel Home-based Intervention for Child and Adolescent Obesity

Anderson Yvonne , Wynter Lisa , O'Sullivan Niamh , Wild Cervantée , Grant Cameron , Cave Tami , Derraik José , Hofman Paul

Background: Whilst multi-disciplinary intervention models for children and adolescents with obesity remain recommended best practice, there is a lack of long-term outcome data, especially in home-based models and programs embedded within the clinical setting. Whānau Pakari is a community-based multi-disciplinary assessment/intervention programme for child obesity, focused on reducing health inequity. Based in Taranaki, Aotearoa/New Zealand, it focusses on...

Introduction: About 15% of children born small for gestational age (SGA) do not reach final height within normal range. Recombinant human growth Hormone (rhGH) has shown to be effective in catching up growth velocity and height in children born SGA.The objective of our study is to identify the predictive factors of final height in children born SGA treated with rhGH.Materials and Methods: Monocentric, retrospective s...

A Novel Stem Cell Model for the Triple A Syndrome

Da Costa Alexandra Rodrigues , Qarin Shamma , Bradshaw Teisha Y. , Watson David , Prasad Rathi , Barnes Michael R. , Metherell Louise A. , Chapple J. Paul , Skarnes William C. , Storr Helen L.

Triple A syndrome (AAAS) is a rare, incurable, recessive disorder, characterised by achalasia, alacrima, adrenal failure and a neurodegenerative phenotype. The AAAS gene encodes ALADIN, is a nuclear pore complex (NPC) protein necessary for nuclear import of DNA protective molecules, important for redox homeostasis. ALADIN’s role is not fully characterised: its discovery at the centrosome and the endoplasmic reticulum suggests a role outside the NPC. To date, the ...
