ARTICLE HIGHLIGHTS
Research background
Emerging studies indicate the critical involvement of microorganisms, such as Epstein-Barr virus (EBV), in the pathogenesis of inflammatory bowel disease (IBD). Immunosuppressive therapies for IBD can reactivate latent EBV, complicating the clinical course of IBD.
Research motivation
This study explored the clinical significance of EBV expression in B lymphocytes derived from IBD patients’ intestinal tissues in detail.
Research objectives
This study aimed to explore the clinical significance of latent EBV infection in IBD patients.
Research methods
Double staining for EBV encoded RNA and CD20 to determine latent EBV infection. The clinic-pathological data were analyzed between the two different latent EBV groups and also between the mild-to-moderate and severe disease groups.
Research results
Systolic pressure, variety of disease, the severity of illness, and pre-op corticosteroids were significantly different between the EBV-negative and EBV-positive groups. Systolic pressure, variety of disease, pre-op corticosteroids and EBV infection were significantly different between the mild-to-moderate and severe disease groups.
Research conclusions
Latent EBV infection is positively related to severity of IBD illness.
Research perspectives
The role of EBV in IBD development should be further investigated; latent EBV infection in patients with serious IBD should be closely monitored.
