Insights
MicroRNA-122 (miRNA-122) levels are elevated in children with Kawasaki disease (KD), correlating with inflammation. This biomarker shows potential for diagnosing KD.
Area of Science:
- Biochemistry
- Pediatric Medicine
- Molecular Diagnostics
Background:
- Kawasaki disease (KD) is a critical pediatric illness.
- Accurate diagnosis of KD is essential for timely treatment.
- Biomarkers for KD diagnosis are actively sought.
Purpose of the Study:
- To investigate the expression pattern of microRNA-122 (miRNA-122) in childhood Kawasaki disease.
- To evaluate the diagnostic value of miRNA-122 in KD.
Main Methods:
- Serum miRNA-122 levels were measured in 150 children with KD and 150 controls.
- Correlations between miRNA-122 and clinical markers (CRP, NT-proBNP, sodium) were analyzed.
- Receiver Operating Characteristic (ROC) curves assessed diagnostic accuracy.
Main Results:
- Serum miRNA-122 levels were significantly higher in KD patients compared to controls.
- miRNA-122 levels positively correlated with CRP and NT-proBNP, and negatively with sodium levels in acute KD.
- The diagnostic performance for KD showed 78.67% specificity and 84.67% sensitivity (AUC=0.8861).
Conclusions:
- Elevated serum miRNA-122 is characteristic of the acute phase of Kawasaki disease.
- High miRNA-122 expression is linked to systemic inflammation in KD.
- miRNA-122 holds promise as a diagnostic marker for Kawasaki disease.
Objective:
To explore the expression pattern and diagnostic value of microRNA-122 (miRNA-122) in childhood Kawasaki disease (KD).
Patients And Methods:
A total of 150 children with KD were included in the KD group. During the same period, 150 children with respiratory infection complicated with fever and without myocardial involvement were included in the control group. Serum level of miRNA-122 in children with acute phase of KD and those in the control group was detected. The relationship between serum level of miRNA-122 and clinical features of KD was analyzed by Pearson correlation test. ROC curves were depicted to assess the diagnostic value of miRNA-122 in KD.
Results:
Serum level of miRNA-122 was higher in the KD group than controls. In the acute phase of KD, the serum level of miRNA-122 was positively correlated to CRP and NT-proBNP, while negatively correlated to the sodium level. The specificity and sensitivity of miRNA-122 in diagnosing KD was 78.67% and 84.67%, respectively (AUC=0.8861, cut-off value=2.905).
Conclusions:
Serum level of miRNA-122 is significantly enhanced in the acute phase of KD, and highly expressed miRNA-122 is related to systematic inflammation. MiRNA-122 may be used as a diagnostic hallmark of KD.
