Introduction: The soluble leptin receptor (sLR) is the main binding protein of leptin in the serum. It reflects the amount of membrane-bound leptin receptors (LEPR) as the sLR is produced by proteolytic cleavage of the extracellular domain of membrane-bound LEPR. Low sLR but high leptin levels were measured in patients with severe obesity. In patients with monogenic obesity caused by biallelic LEPR variants, sLR levels were found to be either undetect...

Carney complex 1 (CNC, OMIM# 160980) is an autosomal-dominantly inherited complex tumor predisposition syndrome associated with skin pigment abnormalities and neoplasms of heart, endocrine glands and other organs. CNC is caused by heterozygous constitutional loss-of-function variants in the PRKAR1A-gene. PRKAR1A codes for the cAMP-dependent protein kinase type I-alpha regulatory subunit, an enzyme that represents an integral part of protein kinase A (PKA) tha...

The effect of GnRHa and testosterone treatment on growth in trans boys

Willemsen Lieve , Boogers Lidewij , Wiepjes Chantal , van Trotsenburg Paul , Klink Daniel , den Heijer Martin , Hannema Sabine

Background: Pubertal growth and adult height are important to many transgender adolescents undergoing medical transition. However, few studies are available on the impact of puberty suppression (PS) with GnRH analogues (GnRHa) and hormonal therapy (HT) with testosterone on growth. In this longitudinal cohort study, we investigated the effect of PS and HT on growth and adult height in transgender boys.Methods: A total of ...

Collection of salivary steroids in children under conditions replicating home sampling

Tonge Joseph , Keevil Brian , Craig Jessica , Langley Joe , Whitaker Martin , Ross Richard , Elder Charlotte

Background: Measurement of salivary glucocorticoids is an accepted method for testing adrenal function and is gaining popularity as it offers a non-invasive collection technique, enabling sampling in the community or home environment, allowing tailored capture of steroid circadian rhythm and improved patient experience. However, there is little data on stability during home collection and sampling methods in young children. Current salivary collection techniqu...

Unstable glycaemia in rare, early-onset Shwachman-Diamond syndrome-associated diabetes mellitus

Navasardyan Lusine , Furlan Ingrid , Brandt Stephanie , Schulz Ansgar , Wabitsch Martin , Denzer Christian

Shwachman-Diamond syndrome (SDS) is a rare congenital disease, which is caused by SBDS gene mutations. The main characteristics of SDS are pancreatic exocrine deficiency, hematological dysfunction, and skeletal growth failure. Emerging data from case reports and patient registries suggest, that SDS could also be associated with an increased risk for diabetes mellitus. Additionally, a small number of case reports in the literature describe a susceptibility to hypoglycaemia as a...

Introduction: As COVID-19 spread across Southeast Asia (SEA) in 2020-2021, healthcare systems in Cambodia, Laos and Myanmar braced as public health officials closed many outpatient diabetes clinics and healthcare professionals (HCPS) were redeployed to COVID-treatment zones. Action 4 Diabetes (A4D) is a UK non-profit organisation that has been providing free insulin and medical supplies to LMICs in SEA since 2016. With historically limited healthcare coverage ...

microRNA-27a - a strand specific regulator of adipogenesis and adipocyte function

Roos Julian , Wu Hang , Pula Taner , Tews Daniel , Wabitsch Martin , Debatin Klaus-Michael , Fischer-Posovszky Pamela

MicroRNAs (miRNAs) are small non-coding RNA molecules and play an important role in the post-transcriptional regulation of gene expression and thereby influence important cellular functions. In adipocytes, miRNAs regulate key processes such as differentiation, inflammation, metabolism, and adipokine secretion. Recently, we found that miR-27a is upregulated under proinflammatory conditions in human adipocytes. Thus, our goal was to better understand the function of miR-27a in a...

Background and Objective: Homozygous mutations in the “Centrosomal Protein-19 (CEP19)” gene are extremely rare causes of early-onset severe monogenic obesity. We, herein, report three siblings with CEP19 mutation.Case Presentation and Method: The index case was a 12-years-old female who presented with severe obesity (BMI:62.7kg/m2), metabolic syndrome and diabetic ketoacidosis. Her non-identical twin female s...

e-REC Capturing The Occurrence and Burden Of COVID-19 Infections In People With Rare Genetic Obesity Disorders

Kerkhof Gerthe , Wabitsch Martin , Bryce Jillian , Johannsson Gudmundur , Ahmed Faisal , van den Akker Erica

Introduction: Following the onset of the COVID-19 pandemic in spring 2020, the European Registries For Rare Endocrine Conditions (EuRRECa), which is a collaboration between Endo-ERN, ESPE and ESE provided the possibility for registration of cases. Obesity is a risk factor for severe COVID-19 disease course in adults. In children and adolescents, COVID-19 disease course is much milder, but has also been identified as risk factor. As rare genetic obesity disorde...
