Objectives: Somatrogon is a long-acting recombinant human growth hormone (GH) approved by the EMA as a once weekly treatment for children with pediatric GH deficiency (GHD). A global phase 3 study compared the efficacy and safety of once-weekly somatrogon with once-daily Genotropin in pediatric subjects with GHD. The objective of this subgroup analysis was to evaluate the efficacy and safety of once-weekly somatrogon vs once-daily Genotropin in the subset of A...

Research Aim: Diabetes type 1 can negatively influence testicular function and fertility but the pathomechanisms on the testicular level remain to be elucidated. Therefore, the aim of the study was to evaluate effects of diabetes mellitus type 1 disease on testicular function.Material and Methods: BB/OKL rats developed type 1 diabetes during adolescence. Rats were treated with different Insulin implants to achieve suffic...

Introduction: Boys born small for gestational age (SGA) often have undermasculinized genitalia. Little is known about the pubertal development and gonadal function on a longer-term in this specific group of males.Aims: To determine the (pubertal) development and long-term urological and endocrine outcome of undermasculinized boys born SGA compared to undervirilized boys born appropriate for gestational age (AGA).<p c...

Summary Answer: Most primordial/primary oocytes were found to have a 46,XX karyotype. Chromosome patterns of the ovarian cells were different from that observed in other tissues.Background: TS is a chromosomal condition associated with partial or complete absence of one of the two X-chromosomes. Females with TS have a limited reproductive lifespan due to an accelerated loss of germ cells. It has been hypothesized that vi...

Background: Mutations in the gene encoding the natriuretic peptide receptor-2 gene (NPR2) are responsible for monogenic growth disorders. Loss-of-function variants cause extreme short stature and skeletal dysplasia. Gain-of-function mutations cause tall stature with - in some cases - macrodactyly of the great toes, a Marfanoid habitus, arachnodactyly and scoliosis. We describe a novel gain-of-function mutation in exon 8 of NPR2 in a family wi...

Introduction: Adrenocortical tumors are very rare in children, with a prevalence of just 0.3 cases/million/year. Autonomic hormone production by adrenal cortical tumors may cause peripheral precocious puberty.Case report: A 4-year-old boy was presented by his parents because of pubertal behavior with aggressive features and a significant increase in the size of the penis. The parents also noticed a strong growth spurt and sweat odor. The boy had a good g...

Background: Being born small for gestational age (SGA) has a negative effect on health-related quality of life (HRQoL) and self-perception. This might be more negatively influenced by postponement of puberty using additional gonadotropin-releasing hormone analogue (GnRHa) treatment.Methods: 154 adolescents born SGA participating in a large Dutch growth hormone (GH) trial (75 with 2 years of GnRHa-treatment) completed the TNO-AZL Adults Quality of Life qu...

SOX3 is located on the X-chromosome (Xq27.1) and encodes a SRY-related protein that acts as a developmental transcription factor. Copy Number Variations (losses and gains), mutations of polyalanine stretches (deletions or expansions) and missense mutations of SOX3 have been associated with growth hormone deficiency with incomplete penetrance, hypogonadism, differences of sexual development and variable additional endocrine disorders (MIM #312000 and #300123)....

Background: GH treatment results in a decrease in fat mass (FM) and insulin sensitivity (Si), and an increase in lean body mass (LBM). Only limited data are available on the longitudinal changes after discontinuation of GH treatment in SGA adults, aged 21 years.Objective and hypotheses: To assess longitudinal changes in body composition (BC) and glucose homeostasis after stop of GH treatment in SGA adults.Method: 197 previously GH-...

Background: Birth weight (BW) is often used as a proxy for gestational age (GA) by studies on preterm birth. Recent data indicate that the terms very-low-birth-weight (VLBW; BW <1500 g) and very preterm (VP; GA <32 weeks) birth are not equivalent with regard to perinatal outcomes and postnatal growth up until final height. It is unknown whether the differences between these terms could be extended to long-term neurodevelopmental outcomes.Objectiv...
