What are the auxiliary examinations for Kawasaki disease?

Many parents hope that their children can live a healthy life and stay away from various diseases. However, there are still many potential disease threats that will have many adverse effects on children's bodies. Kawasaki disease is one of them. Below is an introduction to the auxiliary examinations for Kawasaki disease. I hope it will be of some help to everyone.

Auxiliary examination:

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.

The above content is an introduction to the relevant knowledge about the examination of Kawasaki disease. In life, we must learn more about the relevant knowledge, do more preventive work, pay more attention to a light diet, do not eat spicy or irritating food, pay more attention to rest, and drink more warm water.
