Curve matching to predict future growth in patients receiving recombinant human growth hormone: an interpretable and explainable method using big data

van Dommelen Paula , Arnaud Lilian , Koledova Ekaterina

Background: Prediction models demonstrate potential in predicting growth in patients receiving recombinant human growth hormone (r-hGH) for growth disorders. However, considerable information from patients is needed to calculate a predicted growth curve. The curve matching technique only requires height data. This technique identifies growth curves that are similar (matched) among real-world patients within a database. The growth curves of these ‘matched...

Real-World Data From Electronic Monitoring of Adherence to Growth Hormone Treatment in Children with Growth Disorders: A Descriptive Analysis

Koledova Ekaterina , Tornincasa Vincenzo , van Dommelen Paula

Poor adherence to long-term growth hormone (GH) treatment can lead to suboptimal clinical outcomes. The easypod™ connect eHealth platform enables healthcare professionals to obtain an accurate picture of real-world adherence by allowing patients to transmit adherence data to a database. Our aims were to assess adherence to r-hGH (Saizen, Merck KGaA, Darmstadt, Germany) treatment with the easypod connect platform in children from treatment start to 48 months and to investi...

Follow-up to Adulthood of Two 46,XY Siblings with 5-alpha Reductase Deficiency and Different Sex of Rearing

Chiniara Lyne , Sandberg David , Van Vliet Guy

Background: 46,XY patients with 5α-reductase deficiency (5-ARD), reared from birth as girls, are reported to self-reassign as boys subsequent to a masculinizing puberty; whether this holds true in cases of early orchidectomy is less well documented.Objective and hypotheses: Prepubertal orchidectomy reduces the likelihood of gender self-reassignment.Method: Presentation, management and outcome of two siblings with 5-ARD with na...

Characteristics of a Population of Obese Children and Adolescents: Suggesting a New Paradigm

Van Meter Quentin , Welstead Bethany , Low Joey

Background: Obese children come from families where either one or both parents are obese, suggesting obesity is the result of exposure to detrimental environment.Objective and hypotheses: We propose that inherited insulin resistance is the core which promotes development of obesity and that allergic airway obstruction stalls development of obesity, while peptic gastritis promotes over-eating by confounding portion control.Method: W...

Impact of the COVID-19 pandemic and related lockdown measures on lifestyle behaviours and quality of life in children and adolescents with severe obesity

Welling MS , Abawi O , van den Eynde E , van Rossum EFC , Halberstadt J , Brandsma AE , Kleinendorst L , van den Akker ELT , van der Voorn B ,

Introduction: Lockdown measures following the COVID-19 pandemic are shown to have greatly affected lifestyle behaviours and health-related quality of life (HRQoL) of children. The impact on children with severe obesity has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviours, physical activity (PA), screen time, and HRQoL of children (including adolescents) with severe obesity....

Very preterm infants developing BPD have increased levels of the cortisol precursors 17-OH progesterone and 11-deoxycortisol

Romijn Michelle , Onland Wes , van Keulen Britt , Heijboer Annemieke , Rotteveel Joost , van Kaam Anton , Finken Martijn

Rationale: Bronchopulmonary dysplasia (BPD) is a major complication of preterm birth, which pathophysiology involves systematic inflammation. Preterm infants commonly suffer from relative adrenal insufficiency (RAI) in their first week of life, resulting in an insufficient production of cortisol inappropriate for the degree of inflammation. One of the major causes of RAI is immaturity of adrenal cortex enzymes, leading to an accumulation of cortisol precursors...

Why are Patients with Obesity Due to Leptin Receptor Deficiency not Sufficiently Recognized? Prevalence Estimation Based on European Allele Frequencies and Thoughts on the Discrepancy

Kleinendorst Lotte , Abawi Ozair , van den Akker Erica , Van Haelst Mieke

Background: Biallelic loss of function (LoF) mutations in the leptin receptor gene (LEPR) cause a striking phenotype of early-onset severe obesity and hyperphagia. Additionally, hypogonadotropic hypogonadism, growth hormone deficiency, and/or hypothyroidism are often present. Currently, 19 European patients (all aged <30 years) are described in literature. As clinical trials investigating MC4R-agonist treatment are performed throughout Europe, ide...

Results of Exome Sequencing in Disorders of Sex Development

Kempers Marlies , Claahsen Hedi , Alfen Janielle van , Velden van der , Rinne Tuula

Disorders or Differences of sex development (DSD) are a heterogeneous group of congenital conditions, involving variations of chromosomal, gonadal, or anatomical development. Diagnosis is based on clinical, biochemical, imaging and genetic evaluation. In recent years knowledge about genetic causes has increased, mainly due to improved genetic techniques. In this study we investigated the yield of exome sequencing in our patients with DSD. Patients and methods: Genetic i...

Cut-Off Values for Nocturnal Salivary Testosterone to Enable Detection of Early Puberty

van der Sande Linda J.T.M. , van den Hoogen Chris J. , Boer Arjen-Kars , Odink Roelof J.

Background: In boys with suspected delayed puberty, serum testosterone is used for the evaluation of gonadal function. It is known that early in puberty testosterone levels show a sleep wake rhythm, with nocturnal levels increasing ahead of daytime levels. To evaluate the onset of puberty, the use of salivary testosterone would be an appealing alternative to serum analysis as it is non-invasive and allows multiple nocturnal sampling. Moreover, it is thought that salivary testo...

Molecular Characterization of Testicular Adrenal Rest Tumours in Congenital Adrenal Hyperplasia; Lesions with both Adrenocortical and Leydig Cell Features

Smeets Evelien , Span Paul , van Herwaarden Antonius , Wevers Ron , Sweep Fred , Claahsen-van der Grinten Hedi

Background: Characterization of testicular adrenal rest tumours (TART) are one of the major long-term complications in congenital adrenal hyperplasia (CAH) patients. Although several adrenal-like properties have been assigned to these benign lesions, the exact etiology has not been established yet.Objective and Hypotheses: The aim of this study was to analyze several (steroidogenic) characteristics of TART tissue which may be classified as adrenal cortex...
