Abstract: Background: Prader-Willi syndrome is the most frequent genetic cause of obesity and is
often complicated by glucose metabolism alterations. Conventional therapies prescribed for type 2
diabetes frequently failed to achieve adequate glycemic control in patients with Prader-Willi
syndrome. Beneficial effects of glucagon like peptide-1 receptor agonists exenatide and liraglutide
have been reported for the management of type 2 diabetes in Prader-Willi syndrome, but no data
are currently available in this population on the use of semaglutide.
Case Presentation: We report for the first time the use of semaglutide 1 mg per week in a 33-yearold
man with Prader-Will syndrome complicated by poorly controlled diabetes and severe obesity.
After 12 months of semaglutide treatment, we observed an important reduction in glycated
hemoglobin levels (11.1% to 7.2%) and body weight (99.5 kg to 94.3 kg), with a notable decrease
in fat mass and insulin requirements. Interestingly, our patient had already tried liraglutide therapy
in adjunction to metformin and insulin therapy, reporting no substantial efficacy.
Conclusion: The beneficial effects of semaglutide on glycemic control and weight reduction
provide a promising treatment for diabetes and obesity in Prader-Willi syndrome, even where other
glucagons like peptide-1 receptor agonists have failed. Further studies are required to confirm the
efficacy and safety of semaglutide in patients with Prader-Willi syndrome.
