GH1 and Prader-Willi syndrome: Because the role of myokines in bone and fat metabolism disorders in patients with PWS is still unclear, the aim of this study was to investigate: (a) the concentrations of selected myokines in patients with PWS during GH treatment and dietary intervention in comparison with healthy normal-weight children following an unrestricted age-appropriate diet; (b) the relationships between the studied myokines, bone turnover markers, and adipokines in patients with PWS; and (c) the relationships between the studied biochemical parameters and body composition in these patients.
