While observation studies have shown a positive correlation between inflammatory bowel disease (IBD) and the risk of nonmalignant digestive system diseases, a definitive causal relationship has not yet been clearly established. Methods. Mendelian randomization (MR) was employed to investigate the potential causal association between genetic susceptibility to IBD and nonmalignant gastrointestinal diseases. Genetic variants were extracted as instrumental variables (IVs) from a genome-wide association study (GWAS) meta-analysis, which included 12,194 cases of Crohn\u2019s disease (CD) and 28,072 control cases of European ancestry. The GWAS for ulcerative colitis (UC) included 12,366 UC and 33,609 control cases of European ancestry. All IVs reached genome-wide significance (GWAS <jats:inline-formula><a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><a:mi>p<\/a:mi><\/a:math><\/jats:inline-formula> value &lt;5\u2009\u00d7\u200910\u22128). Summary-level data for acute pancreatitis (AP), irritable bowel syndrome (IBS), gastroesophageal reflux disease, cholelithiasis, and CeD (celiac disease) were obtained from the GWAS meta-analysis and the FinnGen dataset. Summary-level data on relevant inflammatory factors were provided by the International Genetic Consortium. Univariate MR analysis was conducted using inverse variance weighting as the primary method for estimating causal effects. Multivariate MR analyses were also performed to detect possible mediators. Results. Genetic susceptibility to UC was associated with an increased risk of AP (OR\u2009=\u20091.08; 95% CI\u2009=\u20091.03\u20131.13; <jats:inline-formula><c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><c:mi>p<\/c:mi><c:mo>=<\/c:mo><c:mn>0.002<\/c:mn><\/c:math><\/jats:inline-formula>) and IBS odds ratio (OR]\u2009=\u20091.07; 95% confidence interval (CI]\u2009=\u20091.03\u20131.11; (<jats:inline-formula><e:math xmlns:e=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><e:mi>p<\/e:mi><e:mo>&lt;<\/e:mo><e:mn>0.001<\/e:mn><\/e:math><\/jats:inline-formula>). In terms of potential mediators, interleukin 6 (IL-6) had a driving effect on the association between UC and AP. There was no apparent evidence of increased risk with CD. Meanwhile, genetic susceptibility to CD increases the risk of CeD (OR\u2009=\u20091.14; 95% CI\u2009=\u20091.03\u20131.25; <jats:inline-formula><g:math xmlns:g=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\"><g:mi>p<\/g:mi><g:mo>=<\/g:mo><g:mn>0.01<\/g:mn><\/g:math><\/jats:inline-formula>). Conclusions. The evidence suggests that UC is associated with an elevated risk of AP and IBS, and IL-6 may be responsible in AP. CD is associated with an increased risk of developing CeD. Implementing a proactive monitoring program for assessing the risk of gastrointestinal diseases in UC patients, particularly those with elevated IL-6 levels, may be of interest. In addition, the presence of AP and IBS may indicate the presence of UC. Preventing CeD is an essential consideration in the therapeutic management of patients with CD.<\/jats:p>","DOI":"10.1155\/2024\/1266139","type":"journal-article","created":{"date-parts":[[2024,3,18]],"date-time":"2024-03-18T23:05:07Z","timestamp":1710803107000},"page":"1-12","source":"Crossref","is-referenced-by-count":1,"title":["The
