Abstract

BACKGROUND: Fibroblast Growth Factor (FGF) 23 influences endothelial integrity and few reports have studied the association between FGF23 and Kawasaki syndrome (KS), a childhood vasculitis displaying a high risk of subsequent cardiac abnormalities (CaA). AIM: To investigate the genetic variation in the FGF23 gene in a cohort of KS children and its association with serum FGF23 levels and eventual development of CaA, including both coronary artery dilatations and aneurysms. PATIENTS AND METHODS: 84 Italian KS children were recruited; 24/84 (28.6%) developed CaA. Each patient underwent evaluation of serum FGF23 levels and FGF23 genotype: the frequency of the c.212-37insC (rs3832879) polymorphism in intron 1 was examined and compared with sex, age at disease onset, fever duration, laboratory data, and occurrence of CaA. Univariate statistical analysis of categorical parameters was performed by the Pearson's Chi-square test or Fisher's exact test as appropriate. Parametric variables were assessed by Student's t-test for unpaired data. Independent predictors of disease were studied by a logistic regression model. RESULTS: 28/84 patients carried the FGF23 polymorphism (33.3%) and had higher serum FGF23 levels (p < 0.01). FGF23 polymorphism was significantly associated with CaA compared to wild type FGF23 children (respectively, p = 0.03 and p = 0.05). The comparison with demographical, clinical or laboratory data was not significant. CONCLUSIONS: The prevalent segregation of the c.212-37insC polymorphism in children with CaA advocates a possible functional FGF23 role in the predisposition to higher serum levels of FGF23 and potential occurrence of any coronary artery abnormalities in KS.
