Lipid-lowering drugs targets and the risk of hypertensive nephropathy:A drug-target Mendelian randomization analysis

:881-887
 
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.

目的 研究影响新生儿低血糖的相关危险因素。方法 回顾性分析新生儿科570例新生儿的临床资料,其中新生儿低血糖组190例,正常血糖组新生儿380例,采用Logistic回归分析新生儿低血糖相关危险因素。结果 单因素Logistic回归分析显示,新生儿体质量减轻、早产、新生儿呼吸衰竭、新生儿呼吸窘迫、新生儿感染、母亲分娩年龄增大、经产妇、剖宫产、双胎、妊娠期糖尿病、妊娠期高血压疾病是新生儿低血糖发生的危险因素(均P<0.05);多因素Logistic回归分析显示,早产(OR=2.115,95%CI:1.186~3.772)、剖宫产(OR=6.92,95%CI:4.202~11.397)是新生儿低血糖发生的危险因素(均P<0.05)。结论 早产、剖宫产是新生儿低血糖发生的危险因素,应根据危险因素及时识别和治疗新生儿低血糖,为新生儿提供及时产后护理指导,以降低新生儿低血糖发生率。
Objective To study the relevant risk factors of neonatal hypoglycemia.Methods A retrospective analysis was conducted on the clinical data of 570 newborns in neonatal pediatrics,including 190 cases in the neonatal hypoglycemia group and 380 cases in the normal blood glucose group.Logistic regression analysis was used to analyze the risk factors related to neonatal hypoglycemia.Results Single factor Logistic regression analysis showed that neonatal weight loss,premature,neonatal respiratory failure,neonatal respiratory distress,neonatal infection,the mother’s age of delivery,multipara,cesarean section,twins,pregnancy diabetes,pregnancy hypertension were the risk factors for neonatal hypoglycemia,all of which had statistical significance(all P<0.05).In multivariate Logistic regression analysis,premature(OR=2.115,95% CI:1.186-3.772)and cesarean section(OR=6.92,95% CI:4.202-11.397)were risk factors for neonatal hypoglycemia(both P<0.05).Conclusions Premature and cesarean section are risk factors for the occurrence of neonatal hypoglycemia in the local area.Timely identification and treatment of neonatal hypoglycemia based on risk factors,providing timely postpartum nursing guidance for newborns,can reduce the occurrence of neonatal hypoglycemia.

目的 研究高尿酸(UA)和肥胖的交互作用对非酒精性脂肪肝病(NAFLD)患病率的影响。方法 采用病例对照的研究法,选取2021年1月至2021年12月兰州市某医院健康体检中心进行常规健康体检的504人为研究对象,按照诊断标准分为NAFLD组187人和非NAFLD 组317人。采用Logistic 回归模型、相乘、相加交互模型探讨非酒精性脂肪肝病患病风险的影响因素及因素间的交互作用。结果 多因素条件Logistic回归分析可知,肥胖(OR=4.87,95%CI:3.01~7.89),糖尿病患者(OR=3.40,95%CI:1.51~7.68),幽门螺杆菌(Hp)携带者(OR=1.62,95%CI:1.03~2.57),高尿酸血症的NAFLD患病风险增加,分别是正常者、非糖尿病患者、非Hp携带者,非高尿酸血症的4.87倍,3.40倍,1.62倍,2.28倍,在调整混杂因素后交互作用结果显示,高尿酸血症和肥胖对NAFLD患病率有相乘交互作用(OR=0.30,95%CI:0.10~0.88,P=0.029)、但无相加交互作用(相对超额危险度比=3.15、归因比=0.24、协同指数=1.34)。结论 BMI、糖尿病、Hp是NAFLD患病的独立危险因素,其中高尿酸血症和超重与肥胖对NAFLD患病有相乘交互作用,无相加交互作用。
Objective To explore the influence of the interaction of high uric acid(UA)and obesity on the prevalence of non-alcoholic fatty liver disease(NAFLD).Methods Using a case-control study method,504 people who underwent routine health checkups at the health checkup centre of a hospital in Lanzhou City from January 2021 to December 2021 were enrolled in the study,and 187 people were included in the NAFLD group and 317 people in the non-NAFLD group according to the diagnostic criteria.Logistic regression models,multiplicative and additive interaction models were used to investigate the factors affecting the risk factors of NAFLD and the interaction between the factors.Results Multifactorial conditional logistic regression analysis showed that the risk of NAFLD was increased in obese(OR=4.87,95% CI:3.01-7.89),diabetic patients(OR=3.40,95% CI:1.51-7.68),Helicobacter pylori(Hp)carriers(OR=1.62,95% CI:1.03-2.57);the increased risk of NAFLD prevalence in hyperuricaemia patients was 4.87,3.40,1.62,and 2.28 times higher than that of normal,non-diabetic,non-Hp carriers,and non-hyperuricemic individuals,respectively.And the adjusted interaction showed a multiplicative interaction of hyperuricaemia and obesity on the prevalence of NAFLD after controlling for the confounders(OR=0.30,95% CI:0.10-0.88,P=0.029),but no additive interaction (relative excess risk due to interaction=3.15,attributable proportion due to interaction=0.24,and synergy index=1.34) interactions.Conclusions BMI,diabetes mellitus,and Hp were independent risk factors for the prevalence of NAFLD,with hyperuricaemia and overweight and obesity having multiplicative interaction and no additive interaction.
