Calcif Tissue Int:目前尚不能确定可溶性尿酸是否直接影响骨重建

2019-02-17 不详 网络

许多观察性研究报道,血清尿酸盐浓度与骨密度呈正相关,并降低了骨折风险。本研究旨在探究可溶性尿酸是否直接影响骨重建。在实验室研究中,可溶性尿酸盐的体外作用在破骨细胞,成骨细胞和骨细胞测定中检测,尿酸盐浓度范围与人类通常观察到的浓度一致(高达0.70 mmol/L)。使用连续前胶原-1N-末端前肽(P1NP)和来自痛风患者中别嘌呤醇剂量递增的随机对照试验的第12个月骨密度数据评估体外测定结果的临床相关

许多观察性研究报道,血清尿酸盐浓度与骨密度呈正相关,并降低了骨折风险。本研究旨在探究可溶性尿酸是否直接影响骨重建。

在实验室研究中,可溶性尿酸盐的体外作用在破骨细胞,成骨细胞和骨细胞测定中检测,尿酸盐浓度范围与人类通常观察到的浓度一致(高达0.70 mmol/L)。使用连续前胶原-1N-末端前肽(P1NP)和来自痛风患者中别嘌呤醇剂量递增的随机对照试验的第12个月骨密度数据评估体外测定结果的临床相关性。

结果显示,在RAW264.7细胞破骨细胞生成测定中添加尿酸盐导致破骨细胞形成的小幅增加(ANOVA p = 0.018),但骨吸收没有显著差异。在原代细胞破骨细胞生成或再吸收测定中未观察到对破骨细胞数量或活性的显著影响。尿酸盐的添加不改变MC3T3-E1前成骨细胞,原代人成骨细胞或MLO-Y4骨细胞测定中的活力或功能。在临床试验分析中,通过别嘌呤醇剂量递增在12个月内降低血清尿酸盐不会导致P1NP的显着变化或骨矿物质密度的差异。

综上所述,该研究结果表明,在生理浓度下添加可溶性尿酸盐不会影响体外骨重建。这些数据以及显示尿酸盐降低对P1NP或骨密度没有影响的临床试验数据不支持尿酸盐在影响骨重塑中的直接作用。
