Preclinical Studies of Acrodysostosis Gene AAV Therapy in a Knock-In R368X PRKAR1A Mouse Model

Le Stunff Catherine , Gunes Yasemin , Mille Clémence , Bougnères Pierre

The use of recombinant adeno-associated viruses (rAAV) as safe vectors have allowed hundreds of gene therapy attempts to treat monogenic diseases not including bone genetic diseases (Gao G, Nat Rev Drug Dis 2019). To our knowledge, there has been few attempts to apply gene therapy to monogenic bone diseases, largely because most skeletal malformations are being developed during fetal life. Patients affected with acrodysostosis are known to aggravate their skeletal malformation...

Hypercalcemia as a Post Stem Cell Transplantation Complication in Children with Osteopetrosis - A Single Centre Experience

Paul Praveen George , N.A Fouzia , Korula Sophy , Mathai Sarah , George Biju , Simon Anna

Introduction: Osteopetrosis (OP) is a rare genetic disorder that is characterized by abnormal osteoclast function resulting in dense bones and marrow failure. The only definitive cure for OP is stem cell transplantation (SCT). Hypercalcemia is a well described complication in children with OP undergoing SCT. This study describes the calcium profile and treatment modalities used to maintain normocalcemia in children with OP undergoing SCT.<p class="abstext"...

Shox-Haploinsufficiency Intra-Familial Phenotipic Variability and the Impact on Final Height: Report of a Pedigree

Maggio Maria Cristina , Mulè Flavia , Cardella Francesca , Corsello Giovanni

SHOX haploinsufficiency (SHOX-D) is a genetic cause of disharmonic short stature. However, the different impact on phenotype can show differences between patients with the same genotype.GH ameliorates final height, with significant differences between patients for the putative role of environmental factors who can influence growth.We describe the case of two sisters with SHOX-D (target height: 146.8 cm (-2.6SDS); mother: 146.5 cm; ...

Papillary Thyroid Cancer in a 17-Years Old Girl with a Late-Diagnosed Turner Syndrome

Pankratova Maria , Brovin Dmitriy , Kareva Maria

Background: Papillary thyroid cancer has been described in three patients with Turner syndrome (TS) who received growth hormone therapy (Cabanas P, 2005; Bautembach-Minkowska J, 2018). We are presenting a case of papillary thyroid cancer in a girl with a late-diagnosed Turner syndrome who has not received any hormonal therapy up to 17 years.Clinical case: A girl was diagnosed with TS syndrome (karyotype 45XO/46X i(X)q) a...

An Infant with Severe Hypertriglyceridemia: Acute and Long-Term Management in the Paediatric Population

Poon Sarah WY , Tsang Anita MC , Poon Grace WK , Tung Joanna YL

Background: Severe hypertriglyceridemia, defined as triglyceride concentration greater than 11.2 mmol/L, predisposes to acute pancreatitis, a serious complication with mortality rate as high as 6.5% in children (1).Our case highlights the use of insulin infusion to rapidly lower the triglyceride level and the long term management in a young infant with familial chylomicronemia syndrome (FCS) due to lipoprotein lipase deficiency.<stro...

Impact of Insulin Sensitivity and β-cell Function on the Development of Impaired Glucose Tolerance (IGT) in Obese European Children and Adolescents

Denzer Christian , Vogt Josef , Kohlsdorf Katja , von Schnurbein Julia , Wabitsch Martin

Objectives: Compared to the US, prevalence rates of T2DM in obese children are significantly lower in European countries. Data from cohorts of obese children living in the US suggest a concurrent worsening of insulin sensitivity and ß-cell function over the spectrum of glucose tolerance. If these results can be applied to European populations is currently unknown.Methods: A combination of our novel method for mathematical modelling ...

Persistent Beneficial Effects of Metformin in Children and Adolescents with Type 1 Diabetes: Adelaide Metformin Randomized Controlled Trial Follow Up

Maftei Oana , Couper Jennifer , Anderson Jemma , Ricci Peter , Gent Roger , Giles Lynne , Pena Alexia

Puberty is a critical period for the development and acceleration of vascular complications in Type 1 diabetes (T1D). We have shown that metformin in addition to insulin improves vascular smooth muscle function and HbA1c in T1D children over 12 months (1). We aimed to determine if children with T1D who received metformin in a randomized controlled trial (RCT) [Trial registration ACTRN126110001148976] have a sustained vascular function improvement 3 years after ceasing metformi...

Gain in Predicted Adult Height Using the Combination of an LHRH Analogue and an Aromatase Inhibitor in Early Maturing Girls with Compromised Growth for 2 yrs or Until the Age of 11 is Maintained and Further Improved by Aromatase Inhibitor Monotherapy: Results on Final Height of the ‘GAIL’ Study ISRCTN11469487

Papadimitriou Dimitrios T , Dermitzaki Eleni , Papagianni Maria , Kleanthous Kleanthis , Attilakos Achilleas , Mastorakos George , Papadimitriou Anastasios

Background: Third generation aromatase inhibitors (AI) have never been used as monotherapy to increase predicted adult height (PAH) in girls. Our previously published GAIL study (J Endocrinol Invest. 2016 Apr;39(4):439–46) has shown that the combination of anastrozole to an LHRH analogue for 24 months is safe and effective in ameliorating PAH in girls with early puberty +1.21 SDS (+7.51 cm) compared to inhibition of puberty alone +0.31 SDS (+1.92 cm), P=...

Identification of Epithelial Sodium Channel (ENaC) in Endometrial Pipelle Biopsy Samples

Boggula Vijay , Hanukoglu Israel , Sagiv Ron , Enuka Yehoshua , Hanukoglu Aaron

Background: The fluid milieu along the female reproductive tract has a major role in a complex series of events that follow oocyte ovulation. These include oocyte transport in the fallopian tube, the transport and capacitation of sperm, fertilization, transport of the blastocyst and implantation of the embryo in the uterus. These processes are regulated by the activity of ion channels located on the surface of endometrial epithelia. In our previous studies we showed that epith...

The More Obese – The Less Pubertal Height Gain

Holmgren Anton , Niklasson Aimon , Martinez-Villanueva Julian , Martos-Moreno Gabriel A , Argente Jesus , Albertsson-Wikland Kerstin

Background: In a population of a community-based setting (BMISDS range −3.5 to +4.1), there is a negative linear correlation between childhood BMISDS and pubertal height gain, together with earlier onset of pubertal growth with higher BMISDS for both sexes (1).Objective: To investigate the impact of BMI in childhood on the pubertal pattern of growth for obese children in a clinical setting.Met...
