Abstract

Eosinophilic gastroenteritis (EoGE) is a rare digestive disorder characterized by eosinophilic infiltration of the stomach and intestines. In the diagnosis of EoE, it is extremely important to recognize distinctive endoscopic findings and accurately detect increased eosinophilia in gastrointestinal tissues. However, endoscopic findings of EoGE in the small intestine remain poorly understood. Therefore, we conducted a literature review of 16 eligible papers. Redness or erythema was the most common endoscopic finding in the small bowel, followed by villous atrophy, erosion, ulceration, and edema. In some cases, stenosis due to circumferential ulceration was observed, which led to retention of the capsule during small bowel capsule endoscopy. Although many aspects of small bowel endoscopic findings in EoGE remain elusive, the findings presented in this review are expected to contribute to the further development of EoGE practice.

Abstract

Although live-attenuated vaccines are contraindicated under immunosuppression, the immune status of patients with inflammatory bowel disease (IBD) has not been fully assessed prior to immunosuppressive therapy.To investigate antiviral serostatus against viruses requiring live vaccines for prevention in IBD patients undergoing immunosuppressive therapy.This multicenter study included IBD patients who were aged40 years and were treated with thiopurine monotherapy, molecular-targeted monotherapy, or combination therapy. Gender- and age-matched healthy subjects (HS) living in the same areas were included as control group. Antibody titers against measles, rubella, mumps, and varicella were measured by enzyme-linked immunosorbent assays.A total of 437 IBD patients (163 ulcerative colitis [UC] and 274 Crohn's disease [CD]) and 225 HS were included in the final analysis. Compared with HS, IBD patients had lower seropositivity rates for measles (IBD vs. HS = 83.91% vs. 85.33%), rubella (77.55% vs. 84.89%), mumps (37.50% vs. 37.78%), and varicella (91.26% vs. 96.44%). Gender- and age-adjusted seropositivity rates were lower in UC patients than in both CD patients and HS for measles (UC, CD, and HS = 81.60%, 85.29%, and 85.33%), rubella (76.40%, 78.23%, and 84.89%), mumps (27.16%, 43.70%, and 37.78%), and varicella (90.80%, 91.54%, and 96.44%); the difference was significant for all viruses except measles. Divided by the degree of immunosuppression, there were no significant differences in seropositivity rates among IBD patients.IBD patients, especially those with UC, exhibit reduced seropositivity rates and may benefit from screening prior to the initiation of immunosuppressive therapy.
