目的 评估调脂药物靶点所介导的脂质表型（HMGCR、PCSK9和NPC1L1）与高血压肾病风险之间潜在的因果相关性。方法 使用来自欧洲人群公开可获得的全基因组关联研究（GWAS）汇总数据进行孟德尔随机化（MR）分析。采用与低密度脂蛋白胆固醇（LDL-C）相关的遗传变异,根据选定的调脂药物靶基因筛选工具变量,使用逆方差加权法作为主要MR分析方法,并进行敏感性分析确保结果的稳健性。结果 基因预测的LDL-C水平与较高的高血压肾病风险相关（OR=1.19,95% CI：1.03~1.38,P=0.021）。较高的HMGCR介导的LDL-C水平与高血压肾病风险存在正向因果相关性（OR=4.08,95% CI：2.86~5.81;P<0.001）。然而,PCSK9和NPC1L1介导的LDL-C水平与高血压肾病风险无相关性。Cochran Q检验、MR-PRESSO检测和MR-Egger截距测试显示工具变量之间不存在异质性或水平多效性。结论 HMGCR介导的LDL-C与高血压肾病的发病风险存在因果相关性,针对HMGCR基因的他汀类药物在高血压肾病的防治中可能具有潜在益处。

Objective To assess the potential causal relationship between lipid phenotypes mediated by lipid-lowering drug targets（HMGCR,PCSK9 and NPC1L1）and the risk of hypertensive nephropathy．Methods Mendelian randomization（MR）analysis was conducted using summary data from publicly available European ancestry genome-wide association studies（GWAS）．Genetic variants associated with low-density lipoprotein cholesterol（LDL-C）were used as instrumental variables based on selected lipid-lowering drug target genes screening tools．Inverse variance weighting was selected as the main MR analysis method,with sensitivity analyses conducted to ensure the robustness of the results．Results Genetically predicted LDL-C levels were associated with a higher risk of hypertensive nephropathy（OR=1.19,95% CI：1.03~1.38,P=0.021）．Higher LDL-C levels mediated by HMGCR were positively causally related to increased risk of hypertensive nephropathy（OR=4.08,95% CI：2.86~5.81;P<0.001）．However,LDL-C levels mediated by PCSK9 and NPC1L1 showed no significant association with the risk of hypertensive nephropathy．Cochran’s Q test,MR-PRESSO,and MR-Egger intercept tests showed no heterogeneity or horizontal pleiotropy among instrumental variables．Conclusions The findings of this study support the causal relationship between LDL-C mediated by HMGCR and increased risk of hypertensive nephropathy,suggesting potential benefits of statin therapy for hypertensive nephropathy．
