促性腺激素释放激素类似物治疗中枢性性早熟女童及对骨代谢的影响

目的观察中枢性性早熟(CPP)女童给予促性腺激素释放激素类似物(Gn RHa)治疗前后骨代谢标志物的变化,探讨Gn RHa对CPP女童骨代谢的影响。方法选取2013年6月至2014年12月在该院小儿内分泌门诊就诊的初发特发性CPP女童30例(CPP组),采用酶联免疫吸附试验(ELISA法)检测其Gn RHa治疗前和治疗6个月后血清N端中段骨钙素(N-MID)、β-胶原特殊序列(β-Crosslaps)、总Ⅰ型胶原氨基端延长肽(PINP)水平,并与30例同期进行健康体检的女童(对照组)进行比较。结果 (1)CPP组患儿Gn RHa治疗前血清N-MID、β-Crosslaps、PINP水平[(10...

Summary:目的观察中枢性性早熟(CPP)女童给予促性腺激素释放激素类似物(Gn RHa)治疗前后骨代谢标志物的变化,探讨Gn RHa对CPP女童骨代谢的影响。方法选取2013年6月至2014年12月在该院小儿内分泌门诊就诊的初发特发性CPP女童30例(CPP组),采用酶联免疫吸附试验(ELISA法)检测其Gn RHa治疗前和治疗6个月后血清N端中段骨钙素(N-MID)、β-胶原特殊序列(β-Crosslaps)、总Ⅰ型胶原氨基端延长肽(PINP)水平,并与30例同期进行健康体检的女童(对照组)进行比较。结果 (1)CPP组患儿Gn RHa治疗前血清N-MID、β-Crosslaps、PINP水平[(109.3±27.4)、(1.623±0.292)、(847.63±114.88)ng/m L]均显著高于对照组[(73.7±11.3)、(1.191±0.246)、(642.71±152.99)ng/m L],差异均有统计学意义(P〈0.05)。(2)CPP组女童Gn RHa治疗6个月后血清N-MID、β-Crosslaps、PINP水平分别为(77.4±11.7)、(1.204±0.248)、(617.89±163.38)ng/m L,较治疗前均显著降低,差异均有统计学意义(P〈0.05),但与对照组比较,差异均无统计学意义(P〉0.05)。结论 Gn RHa治疗可抑制CPP女童成骨细胞及破骨细胞过度亢进,但短期治疗影响骨量积累的依据不足,长期治疗对骨代谢的影响仍需进一步观察。

Objective To observe the changes of bone metabolic markers in girls with central precocious puberty(CPP)treated by gonadotropin-releasing hormone analog(Gn RHa) and to investigate its effect on bone metabolism. Methods 30 girls with first onset of idiopathic CPP(CPP group) in the pediatric endocrinology outpatient department of our hospital from June 2013 to December 2014 were selected. Serum levels of N-mid fragment of osteocalcin(N-MID),β-crosslaps and total procollagen type I N-terminal propeptide(PINP) before Gn RHa treatment and after 6-month Gn RHa treatment were measured with ELISA. The detection results were compared with those in 30 age-matched girls undergoing physical examination(control group) at the same p
