GH Unmasked Laryngomalacia and worsened Obstructive Sleep Apnea in Infants with Prader-Willi Syndrome

Background: Prader-Willi Syndrome (PWS), due to loss of paternal gene expression on chromosome 15q11.2-13, is characterized by hypotonia, hypothalamic-pituitary dysregulation, abnormal respiratory drive, and hyperphagia. GH, often started in infancy, improves tone, body composition, and height. Concerns about sudden death in children with PWS started on GH, hypothesized secondary to worsening obstructive sleep apnea (OSA) from adenotonsillar hypertrophy, resulted in guidelines...

Background: Prader-Willi Syndrome (PWS), due to loss of expression from genes within the PWS imprinted region at chromosome 15q11.2-13, is characterized by hypotonia and feeding intolerance in infancy with later development of hyperphagia and obesity. Growth hormone improves tone, body composition, and height and can be started in infancy. Morbidity and mortality in PWS include those secondary to hyperphagia and respiratory illness as well as a 17% reported incidence of sudden...
