摘要:

目的·采用两样本孟德尔随机化(two-sample Mendelian randomization,TSMR)方法分析脂质体与原发性高血压的因果关系。方法·原发性高血压的全基因组关联分析(genome-wide association study,GWAS)数据来自FinnGen数据库,脂质体数据来自欧洲生物信息学研究所(European Bioinformatics Institute,EBI)。从EBI的GWAS数据库下载179种脂质体数据,并筛选相关的单核苷酸多态性(single-nucleotide polymorphism,SNP)作为工具变量。采用逆方差加权法(inverse-variance weighted,IVW)、MR-Egger回归、加权中位数法、加权模式法和简单模式法结合敏感性分析,综合评估179种脂质体与原发性高血压之间的因果关联。结果·共筛选出8种与原发性高血压相关的脂质体。IVW显示,6种脂质体增加原发性高血压风险,分别为甘油三酯(52∶3)(OR=1.061,95%CI 1.022~1.101,P=0.002),磷脂酰肌醇(16∶0-18∶1)(OR=1.066,95%CI 1.025~1.107,P=0.001),甘油三酯(50∶2)(OR=1.086,95%CI 1.036~1.139,P<0.001),甘油三酯(54∶3)(OR=1.062,95%CI 1.027~1.099,P<0.001),甘油三酯(50∶1)(OR=1.098,95%CI 1.045~1.154,P<0.001)和甘油三酯(52∶2)(OR=1.071,95%CI 1.035~1.110,P<0.001)。2种脂质体减少原发性高血压风险,分别为鞘磷脂(d40∶2)(OR=0.968,95%CI 0.937~0.999,P=0.042)和磷脂酰胆碱(O-16∶1-18∶1)(OR=0.960,95%CI 0.924~0.998,P=0.038)。其他4种方法显示的因果方向与IVW一致。Cochran′s Q检验显示存在轻微异质性,但对整体结果的稳健性影响有限。MR-Egger回归表明不存在水平多效性。留一法检验表明结果具有较高的稳健性。反向MR分析显示,原发性高血压发病不改变上述脂质体的类型。结论·特定脂质体与原发性高血压存在因果关联。甘油三酯(52∶3、50∶2、54∶3、50∶1、52∶2)和磷脂酰肌醇(16∶0-18∶1)是原发性高血压的危险因素,它们可能通过代谢紊乱促进原发性高血压发生。而鞘磷脂(d40∶2)和磷脂酰胆碱(O-16∶1-18∶1)或对原发性高血压的发生具有保护作用。

Abstract:

Objective ·A two-sample Mendelian randomization (TSMR) approach was employed to investigate the causal relationship between liposomes and essential hypertension. Methods ·Genome-wide association study (GWAS) data for essential hypertension were obtained from the FinnGen database, while lipid profile data were sourced from the European Bioinformatics Institute (EBI). Data on 179 liposomes were downloaded from the EBI GWAS database, and relevant single-nucleotide polymorphisms (SNPs) were screened as instrumental variables. Inverse-variance weighted (IVW), MR-Egger, weighted median, weighted mode, and simple mode methods, combined with sensitivity analysis, were employed to evaluate the causal associations between the 179 liposomes and essential hypertension. Results ·Eight types of liposomes were identified as being associated with essential hypertension. According to the IVW results, six types of liposomes significantly increased the risk of essential hypertension, including triglyceride (52:3) (OR=1.061, 95%CI 1.022‒1.101, P=0.002), phosphatidylinositol (16:0‒18:1) (OR=1.066, 95%CI 1.025‒1.107, P=0.001), triglyceride (50:2) (OR=1.086, 95%CI 1.036‒1.139, P<0.001), triglyceride (54:3) (OR=1.062, 95%CI 1.027‒1.099, P<0.001), triglyceride (50:1) (OR=1.098, 95%CI 1.045‒1.154, P<0.001), and triglyceride (52:2) (OR=1.071, 95%CI 1.035‒1.110, P<0.001). Two types of liposome reduced the risk of essential hypertension, including sphingomyelin (d40:2) (OR=0.968, 95%CI 0.937‒0.999, P=0.042) and phosphatidylcholine (O-16:1‒18:1) (OR=0.960, 95%CI 0.924‒0.998, P=0.038). The causal directions revealed by the other four methods were consistent with those of the IVW method. Cochran′s Q test revealed slight heterogeneity, but its impact on the robustness of the overall results was limited. MR-Egger regression indicated no evidence of horizontal pleiotropy. Leave-one-out cross-validation demonstrated high robustness of the results. Reverse MR analysis indicated that the onset of essential hypertension did not alter the type of the aforementioned liposomes. Conclusion ·There is a causal relationship between specific liposomes and essential hypertension. Triglycerides (52:3, 50:2, 54:3, 50:1, 52:2) and phosphatidylinositol (16:0‒18:1) are risk factors for essential hypertension, which may promote hypertension development through metabolic disturbances. Moreover, sphingomyelin (D40:2) and phosphatidylcholine (O-16:1‒18:1) may have protective effects against the occurrence of essential hypertension.
