The effects of GH substitution on skeletal mass, bone turnover, and calcium metabolism were investigated in 29 patients with GH deficiency who were randomized to sc injections with GH (2 IU/m2 day) or placebo for 12 months. During GH treatment, serum insulin-like growth factor I increased 263 +/- 98% (P < 0.001). Serum osteocalcin, bone a alkaline phosphatase, and procollagen type I C-terminal propeptide increased by 376 +/- 78% (P < 0.005), 128 +/- 17% (P < 0.005), and 100 +/- 17% (P < 0.005), respectively. Serum type I collagen telopeptide and urinary levels of pyridinoline, deoxypyridinoline, and hydroxyproline rose by 158 +/- 39% (P < 0.005), 170 +/- 48% (P < 0.005), 156 +/- 78% (P < 0.005), and 161 +/- 50% (P < 0.005), respectively. Serum ionized calcium rose by 1.7 +/- 0.6% (P < 0.05), whereas serum PTH decreased insignificantly. Vitamin D metabolites remained unaltered. Urinary calcium/creatinine increased and phosphate/creatinine decreased transiently, returning to baseline values at 9 months. When measured by dual energy x-ray absorptiometry, whole body bone mineral density (BMD) and (BMD) of the radius decreased 2.4 +/- 0.6% (P < 0.05) and 3.5 +/- 1.0% (P < 0.005), respectively, whereas no significant changes were observed in BMD of the femur or spine. Our results indicate that long term GH treatment activates bone remodeling in patients with GH deficiency. The observed slight decrease in BMD may be explained by expansion of the remodeling space and reduced mean age of bone tissue. IT remains unclear whether long term treatment with GH will lead to an increase in bone mass and improved skeletal biomechanical competence.
