研究已经证实双膦酸盐可增加成骨不全(OI)患者的骨矿物质密度(BMD)。本研究旨在比较静脉注射唑来膦酸和口服阿仑膦酸钠对OI患者的疗效和安全性。研究共纳入161例2-16岁的OI患者,并以2:1的比例随机分组,每周口服阿仑膦酸钠(ALN)70 mg或每年一次输注唑来膦酸(ZOL)2年。主要终点是腰椎(LS)BMD与基线的百分比变化以及LS BMD的Z分数的变化。结果共有136名OI患者完成了为期2

研究已经证实双膦酸盐可增加成骨不全(OI)患者的骨矿物质密度(BMD)。本研究旨在比较静脉注射唑来膦酸和口服阿仑膦酸钠对OI患者的疗效和安全性。

研究共纳入161例2-16岁的OI患者,并以2:1的比例随机分组,每周口服阿仑膦酸钠(ALN)70 mg或每年一次输注唑来膦酸(ZOL)2年。主要终点是腰椎(LS)BMD与基线的百分比变化以及LS BMD的Z分数的变化。

结果共有136名OI患者完成了为期2年的临床研究,其中90人被分配接受ALN,而46人接受了ZOL治疗。ALN组的LS BMD百分比变化为60.01±7.08%,ZOL组为62.04±5.9%(P = .721)。相应的BMD Z评分在ALN组中增加0.50±0.05,在ZOL组中增加0.71±0.06(P = .013)。 ZOL在降低临床骨折率方面优于ALN(风险比,0.23; 95%置信区间,0.118至0.431)。两组之间严重副作用的发生率无差异。

总之,该研究结果表明,每年一次的5毫克ZOL输注和每周口服ALN在增加骨密度和减少患有OI的儿童和青少年的骨吸收方面具有相似的效果。ZOL在降低临床骨折率方面优于ALN。
