Vaccination in patients with inflammatory bowel disease-Asian perspectives: results of a multinational web-based survey in the 8th Asian Organization for Crohn's and Colitis meeting

Background/Aims: Long-term immunosuppressive therapies used to treat inflammatory bowel disease (IBD) are associated with an increased risk of infections, many of which can be prevented by vaccination. We assessed physicians' current approaches and clinical practices regarding vaccinations for IBD patients in different Asian countries/regions. Methods: An internetbased survey was conducted among members of the Asian Organization for Crohn's and Colitis from September 2020 to November 2020. The questionnaire consisted of 2 parts covering general opinion on the relevance of vaccinations and clinical practice of vaccination. Results: Overall, 384 Asian medical doctors responded to the survey. The majority of respondents considered it very (57.6%) or sufficiently (39.6%) important to perform vaccinations as recommended by the guidelines. About half of the Asian physicians (52.6%) were usually or always performing vaccinations. The influenza vaccine was the most frequently recommended vaccine for IBD patients. Half of the respondents (51.3%) did not recommend hepatitis A vaccine, especially in China (61.6%) and Japan (93.6%). The diphtheria, tetanus, and pertussis vaccine were never (35.2%) or rarely (29.4%) recommended. Conclusions: The findings of this survey indicated similarities among countries/regions in terms of the current approaches and practices regarding vaccination of IBD patients; however, there are some differences that might reflect each country's domestic vaccination guidelines and health insurance particularly with certain vaccines in some countries/regions. Although Asian physicians largely recommend vaccination, more awareness among doctors and Asian consensus regarding differences in IBD vaccination among countries/regions may be required.

Automated summary

This study investigated the current approaches and practices of physicians regarding vaccinations for inflammatory bowel disease (IBD) patients in different Asian countries/regions. The results showed similarities among countries/regions in terms of recognizing the importance of vaccination, but there were differences in the selection and recommendation of certain vaccines, reflecting each country's vaccination guidelines and health insurance. Therefore, more communication among doctors and a consensus regarding IBD vaccination differences in the Asian region are needed.
