Background: Current guidelines recommend the priming with low-dose testosterone in prepubertal boys prior to growth hormone stimulation tests. To our knowledge, only few adverse events after low-dose testosterone have been described so far.Objective and hypotheses: To assess possible side effects of testosterone priming.Patients: We studied 188 prepubertal boys aged between 10 and 15 years (mean ± S.D.: 11.4&#17...

Background: The Scottish Paediatric Endocrine Managed Clinical Network is committed to providing equity of care across Scotland. A key role identified by the nurses group is developing information leaflets supporting patient care. It was recognized that there was no local unified approach to the management of adrenal insufficiency, especially in the home, community and acute setting. Of particular concern was the lack of a pathway of care from home to hospital and involvement ...

Aim: To determine the usefulness of priming with gonadal steroids prior to GH stimulation with clonidine in the evaluation of the GH status of short children.Method: 21 males were studied, with a mean chronological age of 13.2±1.5 years (range 11–16 years), mean bone age 11.0±1.4 years, Tanner stage 1–2, with height 135.8±7.4 cm (Ht-SDS −2.8±0.5), and an inadequate response to an initial GH stimulation test with clonid...

Disorders of sex development (DSD) constitute an array of rare disorders affecting the genito-urinary tract and the endocrine-reproductive system and are often identified in the newborn or adolescent. Gene mutations causing DSD are slowly being identified using high-throughput sequencing, but the interpretation of the data and ascribing causality to novel variants is challenging. This is because DSD mutations occur in multiple genes with each gene affecting a small number of i...

Background/Aim: Currently, the minimum of the GH peak (pGH) to GH provocative stimuli, including the glucagon stimulation test (GST), has been arbitrary set in children at 7 µg/L, irrespective of gender and age. Several doses (fixed or per bodyweight) and ways of administration (IM or SC) of glucagon are being used in daily practice. This retrospective study explores the influence of gender, age, and adiposity on the pGH after a maximally effective glucag...

Background: DMD is an X-linked recessive disorder, due to mutations of the DMD gene on Xp21, encoding dystrophin, characterized by high cytokines and progressive muscle degeneration, with loss of ambulation, increasing immobility and complicated by late cardio-respiratory failure. Use of high dose corticosteroid aims to prolong mobility, delay/reduce complications and to increase lifespan but adverse effects on bone health include bone loss and increased vertebral and long bon...

Introduction: The MAMLD1 gene is expressed in fetal and adult testes. It contributes to the development and formation of the male external genitalia in late stages of fetal organogenesis (week 8-12) and to testosterone biosynthesis. The pathogenic genetic variants of this gene determine a significant reduction in plasma testosterone concentrations, although they are not undetectable. Its most common phenotypic manifestation is hypospadias, also described in patients with micro...

Background: The patatin like phospholipase containing domain 3 (PNPLA3) I148M polymorphism has an effect on modulation of estimated glomerular filtration rate (eGFR) in non-obese non-diabetic adults and in children with histologically confirmed Non-Alcoholic Fatty Liver Disease (NAFLD).Objectives: To explored the impact of PNPLA3 I148M polymorphism on eGFR in obese children with and without NAFLD.<p class="a...

Background: Idiopathic ketotic hypoglycaemia (IKH) is an exclusion diagnosis and the most common cause of hypoglycaemia in childhood. Glycogen Storage disease (GSD) type IX comprises one quarter of all GSD’s. GSDIXa, encoded by PHKA2, is the most frequent subtype.Objective: To investigate whether IKH may be undiagnosed GSDIXa.Methods: Hospital file review and next generation sequence 29 gene GSD-panel.<p class="ab...

Background: Current guidelines recommend that gender dysphoric adolescents be treated with puberty suppression using gonadotropin releasing hormone analogues (GnRHa) followed by cross sex hormones. However limited data are available on the safety and side effects of this treatment. In adults changes in adrenal steroids have been observed during cross sex hormone treatment.Objective and hypotheses: We aimed to investigate the effect of GnRHa and cross sex...
