Abstract
BACKGROUND
Kawasaki disease (KD) is an acute and febrile systemic vasculitis that occurs during childhood. Infliximab (IFX) is a chimeric monoclonal antibody that binds to tumor necrosis factor-α. Although IFX therapy is a useful option for refractory KD, vaccine-associated infections may develop after therapy. In Japan, IFX therapy is recommended after a duration of at least 3 months after live vaccinations or at least 6 months after Bacillus Calmette-Guérin (BCG) in children with KD. However, the appropriate duration between live vaccinations and IFX therapy is unclear.
METHODS
We investigated children who developed KD within 3 months after live vaccinations or within 6 months after BCG. Clinical characteristics, side effects of therapies and efficacy of live vaccinations were retrospectively investigated.
RESULTS
Forty-eight patients developed KD within 3 months of live vaccinations or within 6 months after BCG. Eight patients underwent IFX therapy. There were no apparent vaccine-associated infections. The patients who underwent IFX acquired protective IgG antibody titers in the 5 of 6 live vaccines.
CONCLUSIONS
Safe and appropriate duration between live vaccinations and IFX therapy for KD patients could be shorter in the future, although more studies are warranted to establish the safe duration.
