Efficacy of Glucocorticoid plus Intravenous Immunoglobulin in Children with Immunoglobulin-Insensitive Kawasaki Disease.

This study mainly analyzes the clinical effect of glucocorticoid (GC) plus intravenous immunoglobulin (IVIG) in treating children with immunoglobulin (Ig)-insensitive Kawasaki disease (KD). From September 2013 to November 2021, 86 Ig-insensitive KD children were selected, including 46 children (observation group, Obs) treated with GC plus IVIG, and 40 children (control group, Con) treated with IVIG. The symptom (fever and fever) resolution time, inflammatory factors (C-reactive protein, CRP; procalcitonin, PCT; interleukin-6, IL-6), immune indicators (CD3, CD4, CD8 T lymphocytes CD3, CD4, and CD4/CD8), and incidence of adverse reactions were compared between the groups. The results identified shorter fever and rash resolution time in Obs compared with Con. The posttreatment CRP, PCT, IL-6, and CD8 and the incidence of adverse events reduced notably in Obs and were lower than Con, while CD3, CD4, and CD4/CD8 elevated statistically and were higher than that of Con. Our results indicate that GC plus IVIG can significantly promote symptom resolution, alleviate inflammatory response, and improve immune function in children with Ig-insensitivity KD, with favorable safety and clinical promotion value.
