Bidirectional Mendelian Randomization Analysis of Causal Relationship Between Constipation and Pneumonia增强出版
Bidirectional and two-sample Mendelian randomization(MR) method was used to investigate the bidirectional causal relationship between constipation and pneumonia and to understand the potential relationship between the two diseases from a new perspective, providing new targets for future treatment strategies.
Method
2
Constipation and pneumonia datasets were selected from the genome-wide association study(GWAS) website for the European population in 2021. The data related to constipation included 411 623 samples, and the single nucleotide polymorphism(SNP) data were 24 176 599. The pneumonia data contained 480 299 samples with a number of SNPs of 24 174 646. In this study, inverse variance weighting(IVW) was adopted as the main analysis method of MR, supplemented by weighted median method, simple model, weighted model and MR-Egger regression analysis results, and sensitivity analysis was performed to evaluate the robustness of the results.
Result
2
Seventeen SNPs highly correlated with constipation and 12 SNPs highly correlated with pneumonia were finally included. IVW analysis results of forward MR analysis showed that constipation increased the risk of pneumonia{odds ratio(OR)=1.143, 95% confidence interval(CI)[1.045, 1.249],
P
=0.003}, MR-Egger regression, simple model, weighted model and weighted median analysis all supported the result(
P
<
0.05). IVW analysis by reverse MR analysis showed that pneumonia did not increase the risk of constipation{OR=1.138, 95%CI[0.974, 1.329],
P
=0.103}, MR-Egger regression, simple model, weighted model and weighted median analysis also supported this result.
Conclusion
2
The bidirectional and dual-sample MR analysis method is used to confirm the causal relationship between constipation and pneumonia from the perspective of genetic variation, while there is no obvious causal relationship on the contrary. This study will be helpful for the clinical diagnosis and treatment of constipation and pneumonia, and provide a reference for the study of the pathogenesis between the two.
