Objective: To probe into the expression differences and clinical significance of platelet miR-223 and serum inflammatory factors in children with intravenous immunoglobulin (IVIG)-sensitive and insensitive Kawasaki disease (KD). Methods: A total of 182 children with incomplete KD admitted into the People’s Hospital of Dazu from Apr. 2018 to Nov. 2020 were extracted and divided into IVIG-sensitive group (n=150) and IVIG-insensitive group (n=32) according to the IVIG treatment outcome. Expression of platelet miR-223 was detected by real-time fluorescence quantitative polymerase chain reaction (PCR)
and serum inflammatory factors were detected by enzyme-linked immunosorbent assay kit. The levels of platelet miR-223
serum inflammatory factors and blood routine were compared between two groups. Results: Compared with the IVIG sensitive group
the platelet miR-223
serum tumor necrosis factor α (TNF-α)
interleukin (IL)-1β
and IL-6 increased significantly in the IVIG insensitive group (P<0.05). Multivariate Logistic analysis results showed that C-reactive protein (CRP)
neutrophils/lymphocytes ratio (NLR) and platelet miR-223 were independent risk factors for IVIG insensitivity in children with KD (P<0.05). The receiver operating characteristic (ROC) curve showed that the areas under the curve of platelet miR-223
CRP
NLR and miR-223+CRP+NLR in the diagnosis of IVIG sensitivity in children with KD were respectively 0.964 (from 0.940 to 0.988)
0.811 (from 0.714 to 0.907)
0.903 (from 0.846 to 0.959) and 0.984 (from 0.968 to 1.000). Pearson correlation analysis showed that platelet miR-223 was positively correlated with IL-1β
TNF-α and IL-6 (r was respectively 0.713
0.744 and 0.651
P<0.01). Meanwhile
the expression level of platelet miR-223 in children with coronary artery disease group was higher than that in the non-coronary artery disease group (P<0.01). Conclusion: Combined measurement of platelet miR-223
NLR and CRP levels is of high clinical value in predicting the of IVIG treatment outcome in children with KD
and platelet miR-223 is closely related to the level of serum inflammatory factors and the risk of coronary artery disease.
