Effect of long term glucocorticoid treatment on human growth hormone secretion in children and adolescents and the safety and effectiveness of recombinant human growth hormone treatment / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>Long term glucocorticoid (prednisolone) treatment on human growth hormone (hGH) secretion in children and adolescents and to investigate the effectiveness and safety of the recombinant human growth hormone (rhGH) treatment.</p><p><b>METHODS</b>Twelve patients (age 10.4∓1.2 years) who were treated in Peking Union Medical College Hospital from September 1999 to November 2009 were enrolled in this study. All of them had taken prednisolone with a dose of 0.5∓2.0 mg/(kg.d) for 6~18 months. Two different hGH stimulating tests was done and their growth and development was evaluated at regular intervals. Seven patients were given rhGH with a dose of 0.1 U/(kg.d) for 6~12 months to improve their growth and development after half a year of prednisolone withdrawal when their disease conditions were improved.</p><p><b>RESULTS</b>The growth speed of these 12 children decreased significantly during prednisolone treatment compared with before prednisolone treatment (1.2∓0.3cm/year vs.3.7∓1.2 cm/year,P12 months than those with a 6~12 months course (P0.05). The growth speed of seven children who received rhGH therapy for half a year were increased from 2.2∓0.1cm/year to 7.8∓0.5cm/year (P<0.05), and then to 6.9∓0.4cm/year one year later.</p><p><b>CONCLUSIONS</b>The long-term glucocorticoid treatment can decrease the hGH secretion, and thus leads to short stature and agenesis. However, the rhGH replacement can safely and effectively improve growth and development in these children after their primary diseases are improved and glucocorticoids are withdrawn.</p>
