Low bone mineral density in a growth hormone deficient (GHD) adolescent.

It is largely recognized that Growth Hormone (GH) plays an important role in linear growth during childhood and subsequent completion of appropriate height in early adulthood. It has also significant influence on a variety of metabolic activities, as well as the cardiovascular system and quality of life (QoL) in adults. GH is involved in the attainment of optimal Bone Mineral Density (BMD), the most important predictor of osteoporotic fractures, during the transition from paediatric to adult age. The time interval between paediatric and adult age is a critical period of life to clinically assess persistence of GHD in patients affected by childhood onset GHD (COGHD) and determine the need for continuing treatment with recombinant human Growth Hormone (rhGH) even in the face of closure of epiphyseal growth plates. It has been reported GHD is associated with higher fracture's risk in COGHD patients and GH therapy should minimize, if not prevent, osteoporosis in adulthood. We report the case of a COGHD young man, rhGH treated until final height completion, presenting a wrist fracture and precocious bone density loss.
