循环炎症因子与感音神经性聋之间的因果关系:一项双样本孟德尔随机化研究OACSTPCD

OBJECTIVE To explore the causal relationship of circulating cytokines and sensorineural deafness by Mendelian randomization.METHODS Large-scale genome-wide association studies(GWAS)data sets based on UK Biobank were used to identify single nucleotide polymorphisms(SNP)associated with exposure and outcome.The SNP(F>10)significantly associated with exposure data(P<5e-6)and strongly associated with exposure in the F statistic was selected as the instrumental variable for a two-sample Mendelian randomization analysis.The causal effect was estimated using MR-Egger,regression and inverse variance weighting(IVW).Sensitivity analysis was performed to assess the robustness of the results.RESULTS This study confirmed that VEGF(OR=1.04,95%CI:1.01-1.07,P=0.00),SDF-1α(OR=1.10,95%CI:1.02-1.18,P=0.01)and IL-13(OR=1.04,95%CI:1.01-1.06,P=0.01),IL-10(OR=1.06,95%CI:1.02-1.11,P=0.01),IL-7(OR=1.05,95%CI:1.01-1.08,P=0.00)increased the risk of sensorineural deafness.The backward analysis did not find that sensorineural deafness significantly affected the levels of these cytokines.No significant heterogeneity or horizontal pleiotropy was observed among the instrumental variables.CONCLUSION This study reveals a positive correlation between elevated levels of VEGF,SDF-1α,IL-13,IL-10,and IL-7 with sensorineural hearing loss,providing novel targets for further development of biomarkers for the prediction,treatment,and prevention of sensorineural hearing loss.
