Background: Prader–Willi syndrome (PWS) is characterized by a switch from failure to thrive to excessive weight gain and hyperphagia with impaired satiety in early childhood. An elevated, more unfavorable ratio between acylated:unacylated ghrelin (AG:UAG) may be involved in the underlying mechanisms of this switch.Objective and hypotheses: To assess the evolution of the appetite regulating hormones AG, UAG, and the AG:UAG ratio in infants with PWS a...

Introduction: Individuals with Prader-Willi syndrome (PWS) suffer from hyperphagia, hypotonia and hypothalamic dysfunction, leading to a variety of pituitary hormone deficiencies. Central adrenal insufficiency (CAI) has been reported in PWS, while each of these studies used different testing modalities and cut-off values. Therefore, reported prevalence of CAI ranges from 0% to 60%. It has been speculated that CAI might be responsible, at least in part,...
