PWS European Blood Bank for Infants and Controls From 0 to 48 Months

Sponsor: University Hospital, Toulouse

Summary

The present project aims to determine the underlying mechanisms for the switch from failure to thrive to excessive weight gain and hyperphagia with impaired satiety in PWS. The primary objective is to describe the evolution of circulating hormones involved in feeding and appetite regulation during the 4 first years of life. The secondary objective is to make this blood bank available for other research projects and particularly the investigation of hormones involved in hypogonadism. Over the last ten years, the age at diagnosis in PWS has fallen significantly and the majority of cases is now diagnosed during the 1st trimester of life giving the possibility to collect precise clinical data and serum samples at early stages. The investigators of the project are involved in the care of patients with PWS and have a devoted clinic and an organized network in their country through clinical networks or patient associations.

Official title: Study of Early Endocrine Profile in Infants With Prader-Willi Syndrome (PWS) in Order to Unravel the Switch From Early Feeding Difficulties to Obesity and Hyperphagia.
