This meta-analysis evaluated the efficacy and safety of infliximab as initial therapy for patients with Kawasaki disease (KD) and intravenous immunoglobulin (IVIG) resistant KD. Studies of infliximab in KD, published between January 2004 and December 2019, were curated from PubMed, MEDLINE, and Cochrane Library. Data were analyzed using STATA Version 12.0. Of the 8 studies considered, 4 evaluated the effect of infliximab combined with IVIG as primary therapy in KD, and the remaining investigated the effect of infliximab in IVIG resistant patients. Infliximab was more effective than the control group, with the total summary odds ratio (OR) of 0.34 (95% confidence interval (CI): 0.19-0.62). The treatment resistance of the infliximab group was lower than the IVIG group (0.36 [95% CI: 0.14-0.92]) when infliximab was combined with IVIG as the initial treatment. However, infliximab treatment for IVIG resistant KD was more effective than the IVIG group (0.28 [95% CI: 0.12-0.66]). There was no significant increase in the incidence of coronary artery lesions. The total summary OR for the incidence of coronary artery lesions and infliximab treatment was 0.88 (95% CI: 0.48-1.62). There was no statistically significant difference in adverse events (AEs) when compared between the groups (0.71 [95% CI: 0.44-1.16]).Infliximab combined with IVIG reduced treatment resistance in KD patients vs. conventional IVIG therapy. Infliximab improved clinical course in IVIG resistant KD patients. Infliximab treatment did not reduce the incidence of coronary artery lesions and did not show any significant increase in the incidence of AEs. PROSPERO REGISTRATION NUMBER CRD42020218554.
