Introduction: Most patients with Prader-Willi syndrome (PWS) have a mild to moderate cognitive impairment. Growth hormone (GH) treatment has positive short- and long-term effects on cognition in children with PWS. Few studies, however, have investigated the effects of GH on cognitive functioning in adults with PWS.Objective: To investigate the effects of 3 years GH treatment on cognitive functioning in young adults with ...

Background: Excessive gain in fat mass (FM) during the first months of life, known as the critical window for adiposity programming, is associated with an increased risk for adiposity and cardiovascular diseases in later life. Early life nutrition (breastfeeding or formula feeding) might influence body composition (FM and fat free mass (FFM)) development in early life.Aims: To investigate differences in sex-specific long...

Background and Aims: It has been postulated that the first 3 months of life are critical for programming of adult metabolic health. We investigated if Body Mass Index (BMI) and Fat Mass percentage (FM%) in early life tracks to 5 years of age and if feeding mode influences tracking.Methods: In 268 term born, healthy infants from the Sophia Pluto cohort (161 boys ), BMI was determined at 3 and 6 months, 2 and 5 years o...

Context: Most children with Prader-Willi syndrome (PWS) develop scoliosis. Scoliosis has a prevalence of 80% in children with PWS older than 10 years, who were not treated with growth hormone (GH). GH is an approved treatment for children with PWS and improves psychomotor development and body composition. The onset and progression of scoliosis are generally associated with an accelerated growth velocity and GH treatment might cause accelerated growth. Sinc...

Background: In children with Prader-Willi syndrome (PWS), the benefits of growth hormone (GH) treatment are well established. GH has substantially changed the phenotype of children with PWS. Discontinuation of GH after adult height (AH) attainment leads to a decrease in lean body mass and an increase in body fat percentage. Due to their abnormal body composition, adults with PWS are predisposed to develop impaired glucose tolerance (IGT) and diabetes mellitus type 2 (T2DM). Re...

Changes in abdominal fat distribution in the first months of life might be critical for adult metabolic health. Type of feeding might influence the abdominal fat distribution in early life. This study aims to determine whether type of feeding is related to abdominal fat distribution and whether changes in early life are associated with abdominal fat distribution at the age of 2 years.Methods: In the Sophia Pluto Cohort, infants are examined at age 1 and ...

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...

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: Knowledge about the effect of GH treatment on adaptive functioning in children with Prader–Willi syndrome (PWS) is limited.Objective and hypotheses: The aim of this study was to investigate the effect of GH treatment on adaptive functioning in children with PWS.Method: Vineland Adaptive Behavior Scale (VABS) was assessed at start, at the end of the RCT, and after 7 years of GH treatment. In the RCT, 75 children (42...

Background: IGF1 is mainly sequestered in a 150 kDa ternary complex with IGFBP3 and the acid-labile subunit (ALS). Dissociation of IGF1 from the ternary complex is in part regulated by proteolysis of IGFBP3, which reduces its affinity for IGF1. Short children born SGA have lower IGF1 and IGFBP3 levels compared to healthy peers.Objective and hypotheses: To determine complex formation in healthy normal statured children, and assess variables influencing co...
