Abstract

Background: Previous research demonstrated the association between cyclooxygenase-2 (COX-2) gene polymorphisms and susceptibility to Kawasaki disease (KD). This study aims to detect the plasma concentration of COX-2 in different phases of KD patients and evaluate the relationship between COX-2 level and coronary artery lesion formation, therapeutic response to intravenous immunoglobulin. Methods: Plasma COX-2 levels were measured by enzyme-linked immunosorbent assay in KD patients during the acute (a-KD, n = 52), subacute (s-KD, n = 46), and convalescent (c-KD, n = 43) phase. Results: The concentration of COX-2 in the a-KD group was significantly higher than that in the s-KD, c-KD, healthy control or febrile control group, respectively. There was no difference in the levels of COX-2 between the KD with or without coronary artery lesion subgroups, intravenous immunoglobulin resistant, and sensitive subgroups in the a-KD group, respectively. Conclusions: The plasma concentration of COX-2 might be a novel potential biomarker of acute KD.
