Objective:The aim of this study was to analyze the expression of coronavirus-associated genes[angiotensin-converting enzyme 2(ACE2),transmembrane protease serine 2(TMPRSS2),dipeptidyl peptidase 4(DPP4),aminopeptidase N(ANPEP)]in the intestinal mucosa of patients with inflammatory bowel disease(IBD). Methods:The occurrence of diarrhea in patients with corona virus disease 2019(COVID-19)were collected,and the IBDMDB database was used to analyze the expression of ACE2,TMPRSS2,DPP4 and ANPEP in the intestinal mucosa of IBD patients. Results:The occurrence of diarrhea in COVID-19 patients was 5.8%(136/2 350). Compared with the rectal mucosa,the difference expression fold of ACE2,TMPRSS2,DPP4 and ANPEP in the terminal ileum were 9.800,0.571,5.318 and 11.127,respectively,with statistical differences(P < 0.05). However,the expression of these 4 genes did not show significant differences between IBD and non-IBD patients(P > 0.05). The GO classification showed that these genes were involved in the biological process of the virus entering the host cell,and there was a network interaction between these genes. Conclusion:There is no significant difference in the expression of coronavirus-related genes(ACE2,TMPRSS2,DPP4,ANPEP) in the intestinal mucosa of IBD and non-IBD. We speculate that IBD patients do not have a significantly increased risk of COVID-19.
