Abstract:
Objective:To compare peripheral blood tenascin-C (TN-C) level in patients with Kawasaki disease (KD) on admission, after treatment and at recovery, and to assess the potential of TN-C as a novel predictor for coronary artery lesion.Methods:Retrospective study.Blood samples of 44 KD patients [including 21 patients with coronary artery lesions (CAL + group) and 23 patients without coronary artery lesions(CAL - group)], 39 anaphylactoid purpura patients and 36 non-infected and non-vasculitis controls in the Affiliated Hospital of North Sichuan Medical College during January 1, 2018 and November 1, 2018 were collected.TN-C level was measured by enzyme-linked immunosorbent assay.Normally distributed data were compared by the t test; otherwise, they were compared by the Mann- Whitney U test. Pearson product-moment correlation coefficient or Spearman rank correlation coefficient was used to analyze the correlation between TN-C and other laboratory indexes. Results:For KD patients, TN-C levels on admission [(32.0±13.8) μg/L] and after treatment [(33.5±11.4) μg/L] were significantly higher than that at recovery [(23.3±10.8) μg/L](all P<0.01), which was positively correlated with C-reactive protein ( r=0.317, P=0.038), and negatively correlated with sodium level ( r=-0.472, P=0.004). No significant difference in TN-C level was found between CAL + group and CAL - group [on admission: (31.7±15.4) μg/L vs.(32.3±12.5) μg/L; after treatment: (32.2±11.6) μg/L vs.(34.8±11.3) μg/L; at recovery: (22.6±7.3) μg/L vs.(24.0±13.4) μg/L; all P>0.05]. In addition, TN-C level in patients with KD [(32.0±13.8) μg/L] and anaphylactoid purpura [(37.2±18.2) μg/L] was significantly higher than that of control children [(24.0±8.05) μg/L] (all P<0.01). Conclusions:The study findings are able to prove the potential of peripheral blood TN-C as a predictor for coronary artery lesion in KD patients, nor as a maker of vascular injury.Nevertheless, it may be used as an indicator of immune response in the acute phase of KD.
