Fascinating Growth Phenomena: What Causes Individual Catch-up Growth and Population Secular Change?

Wit Jan M

Catch-up growth (CUG) is characterized by a period of supranormal height velocity following a transient period of growth inhibition. The two classical hypotheses on the mechanism are the neuro-endocrine hypothesis (a central mechanism that would recognize the degree of mismatch between actual size and target size) and the growth plate hypothesis (local regulation of growth according to a preset cellular program of senescence, characterized by decreasing growth proliferation ra...

Individual Patterns of Objectively Measured Adherence to Growth Hormone Treatment and its Effect on Growth in Prepubertal Children with Growth Hormone Deficiency

van Dommelen Paula , Wit Jan M , Koledova Ekaterina

The easypod™ electromechanical injection in combination with the easypod Connect platform electronically records and transmits, in real time, accurate, objective records of the date, time and dose injected for patients receiving Growth Hormone (GH) for growth disorders, limiting the risk of misreporting and allowing physicians to accurately monitor patient behavior.The aim was to study individual patterns of adherence from start treatment up to 24 m...

An Open-Label Phase 2 Dose-Finding Study Comparing Three Different Doses of Weekly TV-1106 and Daily Recombinant Human GH (Genotropin®) in Treatment-Naive, Pre-Pubertal, GH-Deficient Children

Background: TV-1106 (Teva Pharmaceuticals) is a genetically fused human GH and human serum albumin, in development for treatment of GH deficiency (GHD). TV-1106 has an extended duration of action compared to daily GH treatment and thus it is believed that treatment with TV-1106 can reduce the frequency of injections and improve compliance and quality of life for those requiring growth hormone replacement therapy. The efficacy and safety data from adult studies with TV-1106 sup...

Starting recombinant human growth hormone treatment at an early age improves adherence and catch-up growth in patients with growth disorders, and highlights the importance of the new guideline on referral of short children to paediatric care

van Dommelen Paula , Zoonen Renate van , Vlasblom Eline , Wit Jan M. , Beltman Maaike , Arnaud Lilian , Koledova Ekaterina ,

Background: The new preventive child health care guideline for referral of short/tall children facilitates early detection of growth disorders. Understanding the impact of early treatment initiation on recombinant human growth hormone (rhGH) adherence and catch-up growth can support the use of the guideline.Aim: To evaluate the impact of age at rhGH treatment start on adherence (≥85% vs <85% of prescribed doses...

Single nucleotide variations associated with short stature in Baka Pygmies as identified by Whole Exome Sequence (WES)

Introduction: Human growth is a multifactorial process involving genetic, hormonal, nutritional and environmental factors. Genome-wide association studies (GWAS) have shown that >400 genes are associated with adult height. African Baka Pygmies represent an isolated and well-confined small population with short stature of unknown etiology. In previous studies we reported an 8-fold reduced GH receptor gene expression and reduced serum levels of IGF-I and GHB...

Human growth is a complex trait. A considerable number of gene defects have been shown to cause short stature, but there are only few examples of genetic causes of non-syndromic tall stature. Besides rare variants with large effects and common risk alleles with small effect size, oligogenic effects may contribute to this phenotype. Exome sequencing was carried out in a tall male (height 3.5 SDS) and his parents. Filtered damaging variants with high CADD scores were validated b...
