Achondroplasia (ACH) is the most common form of dwarfism, occurring in 1: 20,000 births. ACH is caused by gain-of-function mutations in the fibroblast growth factor receptor 3 (FGFR3) gene that interfere with endochondral ossification. Clinically significant morbidities are frequent in ACH; however, there are currently no approved therapies that target the underlying pathobiology. C-type natriuretic peptide (CNP) is an attractive target as it has the potential to inhi...

Background: Congenital hyperinsulinism (CHI) is a rare disorder, which causes persistent and severe hypoglycaemia in infants and children. CHI can be treated with glucagon, but long-term use is challenging owing to its instability in aqueous solution. Dasiglucagon, a stable glucagon analogue designed for long-term use as a subcutaneous continuous infusion, is in clinical development. Here, we present dasiglucagon safety results in participants treated for up t...

Introduction: With the increasing prevalence of obesity, prediabetes and type 2 diabetes (T2D) in youth are on the rise. Prevention is paramount for these multifactorial diseases. Dietary interventions targeting a reduction of dietary glycemic index (GI) and glycemic load (GL) are potential strategies for improving insulin resistance. However, the association between GI and GL and T2D risk in children remains uncertain.Objectives...

Objective: This feasibility study aimed to investigate the anabolic effect of insulin on metabolites captured in exhaled breath during acute diabetic ketoacidosis (DKA) for a better pathophysiological understanding.Research Design and Methods: Children and adolescents with type 1 diabetes (T1D) with DKA (n=5) and without DKA (n=7) and children with epilepsy without ketogenic diet (n=18) were re...

Background: Wiedemann Steinert Syndrome (WSS) is characterized by distinctive facial features (hypertelorism, thick eyebrows, long philtrum, broad nasal bridge), growth retardation, and intellectual disability of varying degrees. Affected individuals are often born small for their gestational age and have generalized hypertrichosis. Some have growth hormone deficiency, usually partial with normal pituitary MRI. The disease is caused by autosomal dominant varia...

Introduction: Neutropenia is known as a rare adverse event of anti-thyroid drug treatment (ATD) but has also been reported as pre-treatment neutropenia in Graves’ disease (GD). Studies on paediatric patients are rare. To the best of our knowledge, there are no data comparing the effects of methimazole (MMI) and carbimazole (CBZ) treatment in children on the absolute neutrophil count (ANC).Methods: We analyzed retro...

Background: We present the case of a 7-year old girl presenting with undulant ACTH independent Cushing syndrome (CS).Case presentation: The patient presented at a secondary care centre with hyperphagia, fatigue and 8 kg weight increase 4 weeks after an upper airway infection. The parents described a similar episode with spontaneous regression 12 months before. At physical examination she showed a cushingoid habitus with ...

Background: Cardiovascular risk factors largely determine morbidity and mortality in people with type 1 diabetes (T1D). Hyperlipidemia, especially in pediatric patients, is often undertreated, although it can lead to premature atherosclerotic changes. While non-HDL-C (non-HDL-cholesterol) is an important risk factor for cardiovascular events in patients with diabetes, guidelines only define LDL-C treatment targets. According to current ISPAD guidelines, childr...

Background: In patients with SHOX deficiency, radiographic abnormalities can vary, with some cases showing no deformities or only mild deformities, particularly in young children, while Madelung deformity is the most commonly observed radiographic feature. Growth hormone (GH) therapy for individuals with SHOX deficiency has been available in Japan since June 2023. This report summarizes a case series of SHOX deficiency diagnosed at a single institution, with a...

Purpose: Isolated growth hormone deficiency (IGHD) is a rare condition mainly caused by mutations in GH1. The aim of this study was to assess the contribution of GHRHR mutations to IGHD in a very large cohort of patients.Methods: All GHRHR coding exons and flanking intronic regions were sequenced in 312 unrelated patients with non-syndromic IGHD. Functional consequences of all newly identified missense variants were assessed <e...
