The biomarkers associated with coronary artery lesions (CAL) secondary to Kawasaki disease (KD) in Chinese children were investigated by using Meta-analysis. We searched documents published from January 1997 to December 2009 from medical electronic databases. According to inclusion and exclusion criteria, eligible full-text papers were identified. We conducted a comprehensive quantitative analysis by using Stata10.0 statistical software package to assess the heterogeneity among the documents, calculated the summary effect and analyze publication bias and sensitivity. A total of 92 documents and 16 biomarkers were identified. All documents were case-control studies, and included 2398 patients in CAL group and 5932 patients in non-CAL (NCAL) group. The Meta-analysis showed that the levels of platelet count, platelet hematocrit (PCT), neutrophils count, platelet distribution width (PDW), mean platelet volume (MPV), erythrocyte sedimentation rate (ESR), cardiac troponin I (cTnI), and endothelin-1 (ET-1) in CAL group were significantly higher than those in NCAL group, and serum albumin (Alb) and hemoglobin (Hb) levels were significantly lower in CAL group (all P<0.05). White blood cell (WBC) count, serum sodium, matrix metalloproteinase 9 (MMP-9), total cholesterol (TC), hematocrit (HCT) and CD3+T lymphocytes percentage had no statistically significant difference between the two groups. In conclusion, our results indicated that the 10 biomarkers including platelet count, neutrophils count, PCT, PDW, MPV, ESR, cTnI, ET-1, Alb and Hb were associated with CAL, and may be involved in the pathogenesis of CAL. The biomarkers of WBC count, serum sodium, MMP-9, TC, HCT, and CD3+T lymphocytes percentage bore no relationship with the development of CAL among Chinese children with KD.
