Gut Peptides and Bone Remodeling in Children With Neuromuscular Disorders

April 13, 2026 updated by: Bolette Hartmann, University of Copenhagen
Both GIP and GLP-2 reduce bone resorption (measured as CTX) in healthy adult individuals. In this study, we will investigate whether GIP and GLP-2 reduce CTX in children with spinal muscular atrophy, duchenne muscular dystrophy, or cerebral palsy.
