Title: Correlation of Coronary Artery Abnormalities with Fever Pattern in Patients with Kawasaki Disease. Author: Tanaka A, Inoue M, Hoshina T, Koga H. Journal: J Pediatr; 2021 Sep; 236():95-100. PubMed ID: 34019881. Abstract: OBJECTIVE: To investigate the incidence of coronary artery abnormalities (CAAs) by fever pattern after intravenous immunoglobulin (IVIG) therapy in patients with Kawasaki disease. STUDY DESIGN: This retrospective cohort study included 172 patients with Kawasaki disease aged ≤12 years who underwent IVIG therapy and had no CAAs before treatment. Resistance to initial IVIG was defined as persistent fever ≥37.5 °C for ≥24 hours after therapy or the recurrence of Kawasaki disease after initial defervescence. The patients were divided into 3 groups: IVIG responders, nonresponders with persistent fever, and nonresponders with recurrent fever. CAAs were evaluated 2 or 4 weeks and 12 months after onset and were defined by a coronary artery z-score ≥2.5. RESULTS: The incidence of CAAs within 12 months after onset was significantly higher in nonresponders with persistent fever (27%) compared with the other 2 groups. On multivariate logistic regression analysis, being a nonresponder with persistent fever was an independent risk factor for having CAAs within 12 months after the onset of Kawasaki disease (OR, 6.48; P = .007). CONCLUSIONS: In patients with Kawasaki disease resistant to IVIG therapy, persistent fever, but not recurrent fever, was found to be a risk factor for the incidence of CAAs. Aggressive additional therapy may be beneficial to prevent CAA formation in patients with Kawasaki disease with persistent fever.[Abstract] [Full Text] [Related] [New Search]
