Targeted Use of Prednisolone with Intravenous Immunoglobulin for Kawasaki Disease

xlomafota.13 shared this article with you from Inoreader Targeted Use of Prednisolone with Intravenous Immunoglobulin for Kawasaki Disease Via Latest Results for Clinical Drug Investigation Abstract Background and Objectives Intravenous immunoglobulin (IVIG) therapy for acute-stage Kawasaki disease (KD) is the first-line treatment for preventing the development of coronary artery aneurysms (CAA). Corticosteroids (prednisolone) and infliximab are often used in patients at a high risk of CAA or those with CAA at diagnosis; however, there are only a few reports of non-responders to corticosteroids as an adjuvant therapy or rescue alternative to IVIG. In this study, we compared the therapeutic effects of primary and secondary prednisolone with IVIG for KD. Methods We established the following three protocols: A was a secondary rescue prednisolone protocol; B was no prednisolone and second-line infliximab protocol, and C was the primary prednisolone protocol. The indication for prednisolone administration was based on the following: primary prednisolone administration, Kobayashi score; and secondary administration, Shizuoka score. Results Four hundred and sixty-nine patients were enrolled in the three protocols. A comparison between primary and secondary prednisolone and IVIG, as the first-line therapy revealed that the number of first non-responders in C group was 7 (8.3%), which was significantly lower than the 50 (20.9%) in A group. There was a significant difference in the first and second non-responders among the three groups, and the number of non-responders in A group was 6 (2.5%), which was significantly lower than the 13 (9.9%) in B group (p < 0.001, by Bonferroni test). The multivariate logistic regression analysis showed that IVIG non-responders among the protocol groups had an adjusted odds ratio of 6.47. Fifteen IVIG non-responders were administered infliximab as a second-line therapy, and of them, 9 (60%) showed therapy resistance. CAA occurred in 21 patients (4.6%). There was no significant difference among each protocol group. Conclusions The number of IVIG non-responders in the group with prednisolone administration was lower than that in the group without prednisolone administration. Secondary rescue infliximab therapy for IVIG non-responders resulted in a lower defervescence effect than the secondary rescue IVIG with prednisolone administration. Further prospective randomized studies are needed to identify factors useful for preventing IVIG non-responders and determine the optimal rescue therapy for preventing CAA. View on the web Inoreader.
