Abstract The effects of human growth hormone (hGH) therapy on biochemical markers of bone metabolism were studied in 17 children (10 boys and 7girls, aged 3.7–13.1 years old) with idiopathic GH deficiency, before and 1 and 6 months after GH therapy (0.5–0.7 IU/kg weekly, SC). Serum levels of calcium, phosphate, alkaline phosphatase, osteocalcin, parathyroid hormone, 1,25 dihydroxyvitamin D, insulin-like growth factor I (IGF-I) and renal phosphate per 100 ml glomerular filtrate (TPO4/GFR) were assessed. During therapy with hGH, a significant decrease of serum calcium levels and increases of phosphate, osteocalcin, parathyroid hormone 1,25 dihydroxyvitamin D and IGF-I were observed. TPO4/GFR was also significantly increased. Growth response (increment in HV) was positively related with changes in alkaline phosphatase and IGF-I levels after 6 months of hGH therapy. There was also a significant positive correlation between increment in HV and increment in TPO4/GFR after 1 month of GH therapy, whereas no correlation between HV and changes in osteocalcin levels was found. Conclusion GH treatment significantly influences mineral metabolism and the measurement of TPO4/GFR after 1 month of GH therapy may serve as a useful predictor of growth response to hGH therapy in GH-deficient children.
