Abstract:
Objective To investigate the genetic effects of 15 peripheral blood inflammatory factors on the risk of aortic aneurysm and aortic dissection.Methods According to the relevance,independence,and ex-clusion assumptions of Mendelian randomization,instrumental variables predicting C-reactive protein and 14 interleukins(ILs)were extracted from human genome-wide association study data.The associations between these 15 peripheral inflammatory factors and the risk of aortic aneurysm and aortic dissection were investiga-ted using two-sample Mendelian randomization methods,including inverse-variance weighting,MR-PRESSO,and MR-Egger methods.Multivariable Mendelian randomization was used to assess the interactions of these inflammatory factors in influencing disease risk.Cochran's Q test and the MR-Egger intercept were used to e-valuate the heterogeneity and horizontal pleiotropy of the instrumental variables.Results The results of the inverse-variance weighted method showed that increased IL-16 levels were nominally associated with a reduced risk of aortic dissection(OR=0.837,95%CI:0.726 to 0.964,P=0.014).Increased IL-16 and IL-31 levels were also nominally associated with a reduced risk of aortic aneurysm(OR=0.949,95%CI:0.901 to 0.999,P=0.048;OR=0.934,95%CI:0.879 to 0.993,P=0.029).Increased IL-17F levels were nominally associat-ed with an increased risk of aortic aneurysm(OR=1.128,95%CI:1.007 to 1.264,P=0.038).No other in-flammatory factors were found to be associated with the risk of these two diseases using the inverse-variance weighted method.The MR-PRESSO and MR-Egger methods supported the results of the inverse-variance weighted method.Cochran's Q test and MR-Egger intercept test did not detect significant heterogeneity or horizontal pleiotropy.Conclusion IL-16,IL-31,and IL-17F may be involved at the genetic level in the inflam-matory mechanisms underlying the occurrence and development of aortic aneurysms and/or aortic dissections.Among them,IL-16 and IL-31 may play protective roles in aortic aneurysms and/or aortic dissections,whereas IL-17F may have a pathogenic effect on aortic aneurysms.
