JCEM:骨质疏松症患者地舒单抗与双膦酸盐的疗效比较

2018-12-11 xing.T MedSci原创

在12个月和24个月时,相比于双膦酸盐,地舒单抗治疗可显著增加腰椎、髋部和股骨颈的BMD。只有一项研究表明使用地舒单抗可以减少骨质疏松性骨折。需要更长时间的随访和更大样本量的纵向研究来确认疗效差异。

在目前可用的骨质疏松症治疗剂中,医务人员广泛使用了二膦酸盐和地舒单抗。然而,仍然不确定哪种药物治疗更有效。近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,在低骨密度(BMD)或骨质疏松症患者中,研究人员旨在明确相比于双膦酸盐,使用地舒单抗是否会增加BMD,并降低骨折风险。

研究人员检索了PubMed、Embase和Cochrane图书馆,截止至2018年11月,并选择了在低BMD或骨质疏松症的成年患者中比较地舒单抗与双膦酸盐疗效的随机对照试验。研究人员使用随机效应模型进行分析,确定了10个符合条件的试验,共计5361名参与者。

与双膦酸盐相比,研究人员发现使用地舒单抗治疗的患者在12个月时BMD增加,腰椎的平均差异为1.42%(95%CI为0.95-1.89%,p<0.001),髋部为1.11%(95%CI为0.91-1.30%; p<0.001),股骨颈为1.00%(95%CI为0.78-1.22%,p<0.001)。在24个月时,腰椎差异增加为1.74%(95%CI为1.05-2.43%,p<0.001),髋部增加为1.22%(95%CI为0.66-1.77%,p<0.001),股骨颈为1.19%(95%CI为0.65-1.72%,p<0.001)。骨折终点在12个月时没有差异,但在24个月时,地舒单抗治疗的患者骨质疏松性骨折发生率低于阿仑膦酸钠(RR为0.51,95%CI为0.27-0.97)。

在12个月和24个月时,相比于双膦酸盐,地舒单抗治疗可显著增加腰椎、髋部和股骨颈的BMD。只有一项研究表明使用地舒单抗可以减少骨质疏松性骨折。需要更长时间的随访和更大样本量的纵向研究来确认疗效差异。
