How to diagnose Kawasaki disease in children?

Many parents and friends should pay attention to their children's health. When children have some problems, they must actively treat them to help them get better as soon as possible, such as Kawasaki disease. So what is the diagnosis method for Kawasaki disease in children? I will introduce it to you below, hoping to provide some help to friends in need.

Diagnostic criteria

The Japanese Mucocutaneous Lymphadenopathy Research Committee (1984) proposed that the diagnosis of this disease should be confirmed if at least five of the following six main clinical symptoms are met: fever of unknown cause lasting for 5 days or more. However, if coronary artery aneurysm or dilatation is detected by two-dimensional echocardiography or coronary angiography, four of the main symptoms are positive for diagnosis.

Key points for the diagnosis of Kawasaki disease include:

1. Continuous fever, with fever lasting more than 5 days;

2. Red spots appear all over the body. The color of the spots is bright red and gradually turns into dark red;

3. Swelling of the palms and soles, and peeling of the fingertips;

4. The lips are dry, red, and the color is the same as strawberries;

5. Conjunctival congestion of both eyes;

6. Swollen cervical lymph nodes.

The disease can be diagnosed if the above four clinical symptoms are present.

In order to differentiate it from scarlet fever and sepsis, the patient also needs to undergo echocardiography and laboratory tests. Echocardiography can show whether the patient has coronary artery aneurysms, and laboratory tests can tell the patient's specific conditions, such as increased white blood cells and neutrophils. If the urine is checked, it can also be known that the patient's urine is proteinuria. If the liver and kidneys are checked, it can be known whether the patient's liver function is abnormal. If a chest X-ray is done, it can be known whether the patient has a shadow on the chest and whether the shadow is increasing. After a series of tests, the disease can be confirmed.
