Abstract:
Objective:To examine the causal relationship between gut microbiota and noninfectious gastroenteritis using bidirectional Mendelian randomization (MR) approach, so as to provide the basis for the prevention and treatment of noninfectious gastroenteritis.
Methods:Genome-wide association study (GWAS) data of gut microbiota were obtained from the MiBioGen database, comprising 18 340 participants. GWAS data of noninfectious gastroenteritis were obtained from the IEU OpenGWAS database, including 416 adult cases and 7 235 adult controls. The bidirectional MR analysis between gut microbiota and noninfectious gastroenteritis was conducted using inverse-variance weighted method. Sensitivity analyses were conducted using Cochran's Q test, MR-Egger regression, and the MR-PRESSO test.
Results:Forward MR analyses demonstrated statistically significant associations between a higher risk of noninfectious gastroenteritis and Clostridium gangrenexotoxin genus (OR=2.201, 95%CI: 1.295-3.740) and Ruminococcaceae UCG-013 genus (OR=2.683, 95%CI: 1.258-5.720). Conversely, statistically significant associations were observed between a lower risk of noninfectious gastroenteritis and Eubacterium hallii group (OR=0.534, 95%CI: 0.307-0.927), Lachnospiraceae NK4A136 group (OR=0.490, 95%CI: 0.252-0.953), and Oxalobacter formigenes group (OR=0.561, 95%CI: 0.348-0.903). Reverse MR analysis showed no evidence for the causal association between the aforementioned five types of gut microbiota and noninfectious gastroenteritis (all P>0.05). Sensitivity analyses revealed no evidence of heterogeneity or horizontal pleiotropy (all P>0.05).
Conclusion:Clostridium gangrenexotoxin genus and Ruminococcaceae UCG-013 genus were risk factors for the noninfectious gastroenteritis, while Eubacterium hallii group, Lachnospiraceae NK4A136 group and Oxalobacter formigenes group were protective factors for the noninfectious gastroenteritis.
