Abstract:
BACKGROUND:Many foreign studies confirm that recombinant human growth hormone (rhGH) is a safe and effective agent for treatment of idiopathic short stature (iSS), but there are no long-period and systematical researches reported in China.OBJECTIVE: To observe the promoting effect of rhGH on the growth of children with ISS.DESIGN: Case-control observation.SETTING: Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University.PARTICIPANTS: Ninety-eight children with ISS who were treated in the Department of Pediatrics, the Affiliated Hospital of Medical College of Qingdao University during December 2004 to March 2006 were involved in this study.Informed consents were obtained from the guardians of these children with ISS. According to the etiological factors, the children were assigned into 2 groups: ISS group (n =30) and growth hormone deficiency (GHD) group (n =68).METHODS : The children in ISS group and GHD group received subcutaneous administration of home-made rhGH (Jinsai Pharmaceutical Co.,Ltd., Changchun at 0.15 IU/(kg ·d) and 0.1 IU/(kg ·d) respectively before sleeping within 6 months.The body height, body mass and bone age were measured before, 3 and 6 months after treatment. The local region of injection was observed and the growth rate was calculated. Bone age was calculated by graphic atlas method and body height was predicated by BP method.MAIN OUTCOME MEASURES: Body height, body mass, bone age and growth rate of children in two groups before, 3 and 6 months after treatment.RESULTS: All the 98 children wereinvolved in the result analysis, without deletion. ①Intragroup comparison: The body height, growth rate of children in two groups 3 and 6 months after treatment were significantly superior to those before treatment [ISS group: body height:(126.5±9.4), (129.1±8.6), (121.1 ±11.0) cm (P ＜ 0.01), growth rate: (7.3±2.9), (7.5±2.7),(3.5±2.1) cm/year (P＜ 0.01); GHD group: body height: (111.0±13.0),(114.0±13.0),(108.0±12.0) cm(P＜ 0.01),growth rate: (13.2±3.5), (13.5±3.6), (4.0±2.9) cm/year(P ＜ 0.01)]. Six months after treatment, body height was increased in 27 of 30 children in ISS groups, and in all the 68 children in GHD group. ② Intergroup comparison: The growth rate of children in GHD group was concurrently higher than that in ISS group 3 and 6 months after treatment. ③Adverse reaction and side effect: During the treatment, hypothyroidism was observed in 2 children within 1 to 3 months of treatment,but there was no influence on growth rate after oral administration of thyroxin tablets. Local red swelling of skin was observed in another patient, which stopped automatically after one week duration, but the injection continued.CONCLUSION: Home-made rhGH is a safe and effective reagent for treatment of ISS. It can obviously enhance the body height and growth rate of children. Whereas the inhomogeneity of treatment effect does exist, what's more, therapeutic effect in ISS children is inferior to that in GHD children.
