Thyroid Function in Children with Prader-Willi Syndrome, the First 12 Months of GH Therapy

Musthaffa Yassmin M , Hughes Ian P , Harris Mark , Leong Gary

Background: Normal thyroid function is necessary for the optimal growth promoting effects of GH. Changes in the hypothalamic-pituitary-thyroid (HPT) axis following GH have been reported in subjects initially thought to be euthyroid. A specific group of patients, children with Prader-Willi syndrome (PWS), are thought to have a ‘vulnerable’ HPT axis.Objective and hypotheses: To evaluate the impact of paediatric GH therapy on thyroid hormone statu...

Background: Normal TF is necessary for optimal growth. Changes in the hypothalamic-pituitary-thyroid (HPT) axis following GH therapy are reported. GH therapy has been suggested to centrally inhibit TSH production as well as peripherally increasing T4 to T3 conversion which increases negative feedback on TSH production. Hypothalamic dysfunction is a feature of PWS, therefore these patients may be at risk of developing central hypothyroidism associated with GH therapy.<p cla...
