Background: Congenital diabetes insipidus (DI) can be due to mutations in the arginine vasopressin (AVP) gene (familial neurohypophyseal DI), the AVP receptor type 2 (AVPR2) or aquaporin 2 (AQP2) genes (congenital nephrogenic DI, NDI). The clinical manifestation of congenital NDI, especially the response to AVP, can vary greatly depending on the functional effect of the AVPR2 mutation. Here we present two male siblings with NDI and partial response to ddAVP.<p class="abste...

In children with XLH, excess FGF23 causes hypophosphatemia with consequent rickets, skeletal deformities, and impaired growth and mobility. We previously reported that burosumab improved phosphate homeostasis and rickets in children with XLH. Here, we report final data from this Phase 2 Study CL201 (NCT02163577).Fifty-two children with XLH (5-12 years old, Tanner ≤ 2) were randomized 1:1 to receive subcutaneous burosumab every 2 (Q2W) or 4 (Q4W) we...

In children with XLH, excess FGF23 causes hypophosphatemia with consequent rickets, skeletal deformities, and impaired growth and mobility. We reported that burosumab improved phosphate homeostasis and rickets in children with XLH. Here, we present data on 11/52 subjects (all girls) who developed fused growth plates during the phase 2 study CL201 (NCT02163577).In CL201, 52 subjects (Baseline: 5-12 years-old, Tanner ≤ 2) were randomized 1:1 to recei...

The obesity pandemic is likely multifactorial, comprised primarily of reduced caloric expenditure and increased caloric intake secondary to dietary changes, coupled with host genetic predisposition and other environmental exposures. The role of the host microbiome in metabolism, energy expenditure, and metabolic disorders, including obesity, has more recently come under scrutiny as well. For example, several perturbations in the host microbiome have been associated with obesit...

Background: The most prevalent cause of thyrotoxicosis in children is Graves’ disease (GD), and remission occurs only in a modest proportion of patients. The treatment of GD involves the use of antithyroid medications (ATDs), radioactive iodine (RAI; (131I), or surgical thyroidectomy.Objective and hypotheses: This presentation will focus on the risks and benefits of the different treatment options for GD.Method: ATDs are the m...

Background: Congenital adrenal hyperplasia (CAH) is characterised by elevated adrenal androgens which can lead to virilisation of affected females.Objective and hypotheses: To outline clinical opinion on two controversial aspects of CAH management (antenatal dexamethasone and genital surgery of affected females) which was hypothesised would differ between regional centres.Methods: A survey was conducted via the Aus...

Background: Common metabolic diseases, including diabetes and obesity, are the result of interactions between genes and environment. It is well-recognized that the maternal intrauterine environment is an important modifier of this risk. Thus, fetuses carried by women who are obese, diabetic or suffer from suboptimal nutrition are at increased risk of insulin resistance, obesity, type 2 diabetes (T2D), and cardiovascular disease as adults. Emerging data indicate that paternal e...

Background: Congenital adrenal hyperplasia (CAH) is a rare form of adrenal insufficiency characterized by impaired cortisol synthesis leading to excessive adrenal androgen production. Little is known regarding the effects of early and chronic androgen exposure in children with CAH, and whether this exposure may increase the risk of developing attention-deficit/hyperactivity disorder (ADHD) during childhood. The only study on the subject, based on a small sampl...

Real-world studies reporting the impact of continuous glucose monitoring (CGM) in children with Type 1 diabetes (T1D) are limited. In April 2017 CGM became fully subsidised in Australia for children with T1D <21yrs. We report the impact of this in a large population based sample of paediatric diabetes (n=1093). Almost all (99%) children (age < 18yr) with diabetes in Western Australia attend a single paediatric diabetes centre.Pri...

Many factors contribute to the glycemic control in pediatric patients with type 1 diabetes mellitus (T1DM). The purpose of this IRB approved study was to determine if there was a significant correlation between the ability of pediatric patients with TiDM to accurately recognize and count carbohydrates and their hemoglobin A1C (HgbA1C). T1DM patients aged 12-17 years completed the Koontz PedCarbQuiz (PCQ) . Demographic and clinical data was extracted from the electronic health ...
