title: Confirming the diagnosis of growth hormone deficiency (GHD) and transitioning the care of patients with childhood-onset GHD.
abstract: Growth hormone deficiency (GHD) diagnosed in childhood may persist into adult life. After attainment of final height, retesting of the patient's growth hormone-insulin-like growth factor (GH-IGF) axis using the adult GHD diagnostic criteria should be performed after an appropriate interval of 1-3 months off GH therapy. At the time of retesting, other pituitary hormones and serum IGF-I levels should also be measured. The opportunity should be taken to assess body composition, bone mineral density, and fasting lipid and insulin levels. Patients with severe, long-standing, multiple pituitary hormone deficiency, genetic defects, or severe organic GHD can be excluded from GH retesting. When the diagnosis of adult GHD is established, continuation of GH therapy can be recommended unless there is a known risk of diabetes mellitus or malignancy. The patient's transition to GH replacement in adulthood should be arranged as a close collaboration between the pediatric and adult endocrinologists, who should discuss the reinitiation of treatment with the patient.
