血清25-基维生素D水平和肺高血压之间的反向因果关系:一个双样本的门德尔随机化研究
1Department of Cardiothoracic Surgery The Third Affiliated Hospital of Soochow University Changzhou China.
低维生素D水平 (25-氧维生素D) 可能因果性地增加患肺高血压 (PH) 的风险. 这一发现表明,维生素D可能是PH的潜在治疗标.
科学领域:
- 遗传学和流行病学
- 心血管研究研究心血管研究
- 营养科学 营养科学
背景情况:
- 观察性研究表明25-基维生素D (25(OH) D) 与肺高血压 (PH) 之间存在关联.
- 血清25(OH) D水平与PH之间的因果关系尚不清楚.
- 了解这种关系对于确定PH的潜在治疗点至关重要.
研究的目的:
- 调查血清25-基维生素D (25(OH) D水平与肺高血压 (PH) 之间的潜在因果关系.
- 使用门德尔随机化 (MR) 来确定因果关系,克服观察性研究的局限性.
主要方法:
- 采用两个样本的孟德尔随机化 (MR) 设计,使用来自大型全基因组关联研究 (NHGRI-EBI Catalog和FinnGen) 的总结数据.
- 使用逆方差权衡 (IVW) 作为主要分析方法.
- 进行了敏感性分析,包括科克兰的Q测试,MR-Egger拦截和留出一个分析,以评估异质性和性.
主要成果:
- 在基因预测的25(OH) D水平和肺高血压 (OR:0.376,95%CI:0.162-0.876,p=2.334×10−2) 之间观察到显著的逆因果关系.
- 灵敏度分析表明没有显著的异质性或性质的证据,支持研究结果的稳定性.
- 结果表明,较低的25...OH) D水平与PH风险增加有关.
结论:
- 这项MR研究提供了强有力的证据,证明25-基维生素D与肺高血压之间的反向因果关系.
- 这些发现表明,维持足够的维生素D水平可能会对PH发育起保护作用.
- 这一途径需要进一步调查潜在的治疗干预措施,以控制肺高血压.
