目的:系统评价重组人生长激素粉针剂和注射液治疗儿童身材矮小症的有效性与安全性。方法:计算机检索中国知网(CNKI)、维普(VIP)、万方(Wanfang)、中国生物医学文献服务系统(SinoMed)、中国临床试验注册中心、PubMed、Web of Science、EM...目的:系统评价重组人生长激素粉针剂和注射液治疗儿童身材矮小症的有效性与安全性。方法:计算机检索中国知网(CNKI)、维普(VIP)、万方(Wanfang)、中国生物医学文献服务系统(SinoMed)、中国临床试验注册中心、PubMed、Web of Science、EMBase、the Cochrane Library数据库,检索时限均为建库至2024年11月,收集生长激素粉针剂和注射液治疗儿童身材矮小症的随机对照试验(RCT),根据Cochrane风险偏倚评估工具对纳入的文献进行质量评价,运用Stata 18.0软件进行网状Meta分析。结果:最终纳入18篇RCT,总样本量1768例,网状Meta分析显示,生长激素粉针剂与注射液对患儿骨龄、身高、胰岛素样生长因子1(IGF-1)、生长速度、胰岛素样生长因子结合蛋白3(IGFBP-3)及预测成年身高的影响比较差异无统计学意义。基于不良反应发生率进行网状Meta分析,以常规治疗为桥梁时,生长激素的两种剂型间的不良反应发生率比较差异无统计学意义。结论:生长激素注射液和粉针剂治疗特发性矮身材的有效性和安全性相当。由于相关文献数量较少且生长激素用法用量不一致,两种剂型生长激素对生长激素缺乏症的有效性和安全性有待验证。展开更多
