Serum vascular endothelial growth factor: a new predictive indicator for the occurrence of coronary artery lesions in Kawasaki disease

Abstract

We investigated serum vascular endothelial growth factor (SVEGF) levels in Kawasaki disease and determined whether these levels had any association with the development of coronary artery lesions. We measured SVEGF levels in 66 patients with Kawasaki disease, 18 patients with active infections and 18 afebrile controls. SVEGF levels of patients in the acute phase of Kawasaki disease (0.0-2003.6 pg/ml, median 59.87 pg/ml) were significantly higher than those of patients with active infections (0.0-45.2 pg/ml, median 8.10 pg/ml; P < 0.05) or afebrile controls (0.0-49.8 pg/ml, median 7.75 pg/ml; P < 0.05) and decreased to undetectable or low levels in the recovery phase (n = 31, acute phase: 0.0-2003.6 pg/ml, median 62.50 pg/ml versus recovery phase: 0.0-146.5 pg/ml, median 26.90 pg/ml; P = 0.0007) of the disease. There existed a positive correlation between SVEGF levels and serum C-reactive protein concentrations in the acute phase of Kawasaki disease (rs = 0.347, P = 0.0051). In addition, SVEGF level and duration of fever were found to be major risk factors for the occurrence of coronary artery lesions by univariate (P = 0.012 and P = 0.003, respectively) and multivariate (P = 0.037, OR 6.16 and P = 0.0059, OR 7.59, respectively) analyses. Serum vascular endothelial growth factor level, in combination with persistence of fever, could be a powerful predictor for the development of coronary aneurysms.
