    Kawasaki Disease: Meaning, Symptoms & Treatment

    Updated on 3 November 2023

    Children have weak immune systems, and they often suffer from minor diseases. However, some genetic diseases are also common among some children. One such ailment is Kawasaki disease. This disease causes inflammation in children's arteries, making them suffer from fever and Kawasaki rash. One does not need to be afraid of this disease as it is a temporary condition that usually subsides within a few days under medical supervision.

    What is Kawasaki Disease?

    Parents need to know what is Kawasaki disease to save children from it and ensure their speedy recovery if diagnosed with it. In medical terminology, Kawasaki disease or Kawasaki syndrome is called mucocutaneous lymph node syndrome. It causes inflammation in the walls of small and medium-sized blood vessels in children.

    Furthermore, the disease can lead to an inflammation in the coronary artery, the arteries responsible for carrying oxygenated blood to the heart. It can also lead to swelling in the glands and mucous membranes.

    Kawasaki disease symptoms

    Some of the common Kawasaki disease symptoms are as follows -

    • Fever greater than 102.2F or 39 C

    • Kawasaki disease rash on the skin of the children

    • Swelling of the lymph node

    • Red eyes or conjunctival injection

    • Cracked and dried red lips and extremely red tongue or Kawasaki disease tongue

    • Swelling in hands and feet, which eventually turns red in color.

    • Abdominal pain

    • Diarrhea

    • Drowsiness and vomiting

    • Joint pain

    • Jaundice

    • Skin peeling on the feet and hands

    Causes of Kawasaki disease

    The accurate causes of Kawasaki disease are not yet understood. However, some factors can be regarded as the cause of this disease. Kawasaki disease causes are as follows -

    Viral or bacterial Infection

    Some of the Kawasaki symptoms, such as rash Kawasaki disease, indicate that it is similar to an infection caused by viruses or bacteria. However, it is not yet ascertained whether viruses or bacteria cause it.

    Autoimmune disorder

    Autoimmune disorder can also cause Kawasaki disease. In this condition, the body’s immune system becomes a pathogen and attacks the healthy tissues causing this disease.

    Genetics

    Parents with a history of Kawasaki disease are more likely to pass it on to their children through their genes.

    Diagnosis of Kawasaki disease

    The diagnosis of Kawasaki disease depends on the Kawasaki disease symptoms that appear in a child. Some common tests are done to test the health of the blood and heart include the following -

    • Urine test - To check whether some other disease has caused the symptoms.

    • Platelet count test - Platelets are often very high in Kawasaki disease.

    • Erythrocyte sedimentation rate test - This test checks any inflammatory condition in the body.

    • Sodium test - In Kawasaki disease, children often have low sodium levels in their bodies.

    • CRP test - This test is also done to check for inflammation in the body.

    • Albumin test - A low albumin level in blood confirms Kawasaki disease in children.

    Tests that are done to check the health of the heart are as follows -

    • ECG test - This test is done to check the heart rhythms and see if everything is perfect. Electrodes are attached to the skin, and the heart's impulse is observed to check the heart's health.

    • Echocardiogram - It is an ultrasound test used to determine the heart's pumping action using sound waves.

    Treatment of Kawasaki disease

    Kawasaki disease is treated using some oral medications such as -

    • Aspirin

    • Intravenous immunoglobulin

    • Corticosteroids and tumor necrosis factor inhibitors

    • Anticoagulant medications

    However, if these medications do not help, a surgical procedure called Coronary artery angioplasty is done to open up the blocked artery. Furthermore, a stent is also placed to reduce the risk of the blockade in the future.

    Complications of Kawasaki disease

    If not properly treated, Kawasaki disease can lead to serious complications such as an aneurysm. Moreover, it can also increase the risk of heart attack or internal bleeding in children. Some other major complications include -

    • Myocarditis

    • Pericarditis

    • Malfunctioning of cardiac muscle and heart valves

    • Heart failure

    Who's affected by Kawasaki disease

    The Kawasaki syndrome or Kawasaki disease primarily affects small children below the age of 5. Boys are more likely to be diagnosed with this disease. Children of people of Asian or pacific descent have a very high chance of getting infected with Kawasaki disease.

    When to see a GP

    A parent needs to see a general practitioner or GP as soon as any of the Kawasaki disease symptoms appear in their children. If fever is persistent in a child and parents can observe some red rashes developing on their children, they should not waste any time. Kawasaki disease must be treated as early as possible to avoid serious complications in children. Children with proper treatment recover fully from this disease in six to eight weeks.

    So this was everything a parent needs to know about Kawasaki disease and the symptoms of this disease. And one should not delay getting the right treatment for their kids once they see any of the symptoms mentioned above in their child.
