摘要
目的比较阿仑膦酸钠和阿法骨化醇治疗原发性骨质疏松症的效果。 方法检索电子数据库,并追溯纳入文献的参考文献,收集随机对照试验(RCTs),对其进行质量评价和资料提取,而后采用RevMan5.1和Stata11.0软件进行统计分析。 结果纳入7个RCTs,包括1216例患者,服用阿仑膦酸钠患者578例,服用阿法骨化醇患者638例。骨折方面,相比阿法骨化醇,阿仑膦酸钠降低脊椎的骨折风险更有优势[OR=0.46,95%CI(0.32,0.66),P<0.0001,I2=0%],亚组分析结果提示在有骨折病史,随访时间大于24个月和无制药公司赞助的亚组中,阿仑膦酸钠更有优势,但亚组间差异性不显著。阿仑膦酸钠和阿法骨化醇在降低非脊椎的骨折风险方面没有显著性差异[OR=0.98,95%CI(0.42,2.31),P=0.96,I2=0%]。骨密度方面,在12月、24月和36月阿仑膦酸钠比阿法骨化醇对提高腰椎骨密度均有显著优势[WMD=4.48,95%CI(4.35,4.61),P<0.00001,I2=98%;WMD=5.56,95%CI(5.37,5.75),P<0.00001,I2=98%;WMD=7.55,95%CI(7.35,7.76),P<0.00001,I2=73%]。消化道副作用方面,两者没有显著性差异[OR=1.25,95%CI(0.84,1.86),P=0.27,I2=18%]。敏感性分析显示结果稳定。 结论本篇荟萃分析显示阿仑膦酸钠比阿法骨化醇在降低脊椎骨折风险和提高腰椎骨密度方面有显著优势,而且两者的消化道副作用并没有显著性差异。因此,治疗原发性骨质疏松症患者时,阿仑膦酸钠相比阿法骨化醇将会是个更优的选择。
