Background: Peak stimulated growth hormone (GH) levels are known to decrease with increasing BMI, possibly leading to overdiagnosis of GH deficiency (GHD) in children with overweight and obesity. However, current guidelines do not provide guidance how to interpret peak GH values of these children. The aim of this systematic review and meta-analysis was to study the effect of BMI standard deviation score (SDS) on stimulated peak GH values in children, to identi...

Background: For early identification of patients requiring adherence support, objective, real-time adherence data are needed. The easypod™ electromechanical injection device, in combination with the easypod™ connect ecosystem, electronically records and transmits, in real time, accurate records of the date, time and dose injected for patients receiving recombinant human growth hormone (r-hGH) to treat growth disorders. Healthcare professionals can us...

Objective: Congenital Adrenal Hyperplasia (CAH) requires life-long replacement of cortisol. However, this long-term GC-treatment could change the developmental trajectory of the brain and predispose patients to problems with cognition and mood regulation. Previously, we have found impairments in working memory in patients with CAH, as well as alterations in brain structure in regions of the central executive network (CEN). These changes could be associated wit...

Background: Transient or permanent hypoparathyroidism is one of the most well-known complications of total thyroidectomy and may lead to symptomatic hypocalcaemia. Treatment of post-thyroidectomy hypocalcaemia usually consists of postoperative calcium and/or vitamin D supplementation. In 2013 we implemented prophylactic pre-thyroidectomy calcitriol supplementation for all children undergoing total thyroidectomy at Amsterdam UMC. The objective of this study was...

Background: Graves’s disease (GD) is the most common cause of hyperthyroidism. Maximal 30% of pediatric GD patients achieve remission with anti-thyroid drugs. The majority of patients therefore require definitive treatment. Both thyroidectomy and radioactive iodine (RAI) are often used as definitive treatment for GD. However, data on efficacy, and short- and long-term side effects of RAI treatment for pediatric GD are relatively scarce.Methods: A ...

Objective: Oral hydrocortisone medication for Congenital Adrenal Hyperplasia (CAH) could lead to suboptimal blood cortisol levels throughout the day. In addition, the HPA-axis is rendered inflexible in patients. Cortisol is crucially involved in the stress response as well as in generating and regulating emotional responses to stimuli. Sub-optimal cortisol levels, in combination with a less flexible HPA-axis, could therefore lead to problems with emotion regul...

Background: Monitoring adherence to growth hormone (GH) treatment is important, because poor adherence can lead to suboptimal clinical outcomes. The easypod™ electromechanical injection device in combination with the web-based easypod™ connect platform electronically records and transmits accurate, objective records of the date, time and dose injected of patients receiving GH with growth disorders, allowing physicians to accurately monitor patients&#...

Introduction: Consensus guidelines (2021) state that a second dry blood spot (DBS) should be considered for newborn screening (NBS) in preterms (delayed TSH rise).Objective: To evaluate the diagnostic yield of an NBS strategy including a second DBS at 14 days in preterms.Material and Methods: Retrospective study of 2 cohorts. Cohort 1: live births <37 weeks of gestational age (G...

Background: Short stature has been associated with a reduction in health-related quality of life (HRQoL) and more problem behavior in children and adults. In adolescents who were treated with growth hormone (GH) because of persistent short stature after being born SGA, an increase in HRQoL and decrease in behavioral problems was seen during or right after cessation of GH-treatment. However, long-term data, to analyze if these positive effects remain many years...

Background: Central hypothyroidism is rare in children. It is often part of multiple pituitary hormone deficiency but can occur in isolation. Isolated central hypothyroidism may be due to mutations in TSHB, TRHR or IGSF1, involved in TRH signalling. We present an adolescent with a novel truncating variant of IGSF1, resulting in delayed puberty, central hypothyroidism and macroorchidism.Case presentation: A 15-year-old ma...
