What are the common tests for Kawasaki disease in children?

In our daily lives, we should learn more about some common knowledge about diseases, which can help ourselves cope with them better. Take Kawasaki disease for example. Many people are not very familiar with it. So what are the common examinations for Kawasaki disease in children? Here is a brief introduction for you.

Common inspections:

In the acute phase, the total white blood cell count and percentage of granulocytes increase, and the nuclei shift to the left. Mild anemia can be seen in more than half of the patients. The erythrocyte sedimentation rate increases significantly, reaching more than 100 mm in the first hour. Serum protein electrophoresis shows an increase in globulin, especially a significant increase in α2 globulin. Albumin decreases. IgG, IgA, and IgA increase. Platelets begin to increase in the second week. The blood is in a hypercoagulable state, and the antistreptolysin O titer is normal. Rheumatoid factor and antinuclear bodies are both negative. C-reactive protein increases. Serum complement is normal or slightly high. Urine sediment shows leukocytosis and/or proteinuria. Electrocardiograms can show a variety of changes, with abnormal ST segment and T wave being the most common, and can also show prolonged PR and QR intervals, abnormal Q waves, and arrhythmias.

Two-dimensional echocardiography is suitable for cardiac examination and long-term follow-up. Various cardiovascular lesions such as pericardial effusion, left ventricular enlargement, mitral regurgitation, and coronary artery dilatation or aneurysm formation can be found in half of the patients. It is best to check once a week during the acute and subacute stages of the disease. It is the most reliable non-invasive examination method for monitoring coronary artery aneurysms. In cases of aseptic meningitis, the number of lymphocytes in the cerebrospinal fluid can be as high as 50-70/mm3. In some cases, slightly higher serum bilirubin or alanine transaminase can be seen. Bacterial culture and virus isolation are both negative results.

This is our introduction to the relevant examination methods for Kawasaki disease. Kawasaki disease is common and the impact is very serious. We must take Kawasaki disease seriously. After understanding the examination methods for the disease, it can help us a lot in dealing with Kawasaki disease. We must pay attention to the prevention of Kawasaki disease in our lives.
