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.

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Mitral Regurgitation II: Clinical Features and Diagnostic Tests

Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...
