Ideal Vaccination Strategy in Inflammatory Bowel Disease / 대한소화기학회지

ABSTRACT

Inflammatory bowel disease (IBD) is a long-standing disease that often requires long-term use of immunosuppressive agents including immunomodulators (such as azathioprine, 6-mercaptopurine and methotrexate) and tumor necrosis factor-alpha inhibitors (such as infliximab and adalimumab). Introduction of immunosuppressive therapies, however, involves the risk of host susceptibility to opportunistic infections in this patient population. Therefore, adequate immunization for vaccine-preventable infectious diseases is currently recommended for all patients with IBD and is emerging as an important target for quality improvements in IBD care. However, ongoing issues regarding underuse of immunization, safety and efficacy of vaccines in patients with IBD remain. For quality improvements in IBD care, all physicians should follow the recent immunization guidelines proposed by professional IBD societies. Additionally, there are ongoing needs for intensive educational programs regarding a role of immunization in long-term care of IBD and up-to-date immunization guidelines. Immunization status should be checked at the time of diagnosis of IBD and timely vaccination before initiation of immunosuppressive therapies can be a practical solution for maximizing the efficacy of vaccination at this point. Inactivated vaccines can be used safely irrespective of immunization status of patients, while attenuated vaccines are contraindicated in patients on immunosuppressive therapies. This article reviews an ideal strategy for vaccinating patients with IBD based on the currently recommended immunization guidelines.
