Kawasaki Disease: Causes, Symptoms, Diagnosis & Treatment

by admin

What is Kawasaki Disease?

Kawasaki Disease, sometimes called Kawasaki Syndrome or Mucocutaneous Lymph Node Syndrome, primarily affects children younger than five years of age and is considered a pediatric rheumatic fever. If not treated, it might induce systemic inflammation of blood vessels, which can have dire consequences.

Infection or other environmental factors may generate an aberrant immunological response, which is thought to be at the root of Kawasaki Disease. Symptoms of the condition include a high fever that lasts for at least five days, as well as additional symptoms include swollen lymph nodes, red eyes, cracked lips, and rashes on the hands and feet.

Heart muscle destruction (myocarditis), coronary artery aneurysms (bulges in the walls of the arteries), and even heart attack are all potential outcomes of untreated Kawasaki disease.

Diagnosis of Kawasaki Disease involves a physical examination by a doctor followed by various tests such as blood tests, electrocardiogram (ECG), echocardiography (ultrasound imaging) of the heart etc.

Early diagnosis followed by timely treatment with intravenous immunoglobulin (IVIG) is key in managing this disease effectively. Nevertheless, prevention remains elusive due to lack of knowledge about its underlying causes.

Causes of Kawasaki Disease

The root cause of Kawasaki disease has yet to be identified. However, an aberrant immunological response to an infection or virus is thought to be the root cause. Genetic factors may play a role in the onset of Kawasaki disease, according to some research.

Infectious agent may trigger an autoimmune response which leads to inflammation and damage within the walls of blood vessels, specifically in the coronary arteries. This can result in weakened arterial walls and potentially lead to complications such as heart disease or even heart attack.

The likelihood of contracting Kawasaki disease may rise with age, male gender, and/or non-Caucasian ethnicity. Young children (under the age of five) and boys more so than girls are most at risk.

There is currently no cure or preventative measure for Kawasaki disease, however getting medical treatment right once if your child shows signs will help lessen the severity of the illness.

Symptoms of Kawasaki Disease

Kawasaki Disease is a rare illness that primarily affects children younger than five years old. However, it can affect children up to the age of 13 years. The symptoms of Kawasaki disease usually develop in three different stages and can last for several weeks.

  • In the first stage, which lasts for about ten days, symptoms may include high fever (over 38°C), redness in both eyes without any discharge, swollen lymph nodes in the neck region, cracked lips and a strawberry-like tongue with white coating or dots on it.
  • In the second stage lasting from two to four weeks after onset of symptoms, peeling skin on hands and feet may occur as well as joint pain and swelling on large joints such as knees.
  • The third stage is when symptoms have subsided but patients are still recovering. During this period patients may feel fatigued or weak. It’s crucial to keep in mind that not every child will exhibit every symptom; some kids might have none, while others might have several.

It’s essential that parents seek medical advice if their child experiences any persistent unexplained fever coupled with other associated symptoms mentioned above. Early diagnosis and prompt treatment are crucial steps towards better outcomes for affected individuals

Diagnosis of Kawasaki Disease

Due to the lack of a reliable diagnostic test, Kawasaki disease can be difficult to diagnose. Clinical symptoms, a patient’s medical history, a physical exam, and laboratory tests are the main tools doctors use to make a diagnosis.

  • Physical Examination. Eye redness, lymph node swelling, skin rashes, and abnormalities in the mouth and throat are just some of the symptoms examined by doctors during a physical. Heart sounds are also listened to for abnormalities.
  • Blood Tests. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels in the blood are measured. These biomarkers serve as early warning signs of systemic inflammation.
  • Echocardiograms and electrocardiograms are two more methods doctors may use to assess cardiac health.

To make a diagnosis of Kawasaki Disease certain criteria must be met including fever lasting more than five days along with at least four out of five primary symptoms. If your child has been diagnosed with KD early treatment is essential so don’t wait if you suspect these symptoms!

Treatment of Kawasaki Disease

Kawasaki disease treatment centers on lowering inflammation and avoiding complications. To prevent further heart damage, treatment should start as soon as feasible.

  • Common medications used in treating Kawasaki disease is intravenous immunoglobulin (IVIG). This medication helps reduce inflammation, fever and rash. It’s most effective when given within 10 days of symptom onset.
  • Aspirin is used in treating Kawasaki disease. It’s administered at high doses during the acute phase to reduce inflammation and prevent blood clots from forming. Once fever has subsided, aspirin may be continued for several weeks or months at a lower dose to prevent blood clots.
  • Corticosteroids or tumor necrosis factor inhibitors may be necessary if IVIG doesn’t work or if there are severe symptoms like myocarditis or aneurysms.

Early diagnosis and prompt treatment are crucial in managing Kawasaki disease effectively. Close follow-up with a healthcare provider after treatment is also essential to monitor for any potential long-term complications.

Prevention of Kawasaki Disease

Protecting kids from Kawasaki disease is a top priority for parents. The difficulty of complete prevention stems from the fact that the disease’s exact etiology is unknown. However, problems from the sickness can be mitigated if it is diagnosed and treated quickly. Here are some ways to avoid getting Kawasaki disease:

1. Maintaining hygienic personal conduct. Using soap and water or an alcohol-based hand sanitizer frequently is a part of this practice. In order to prevent the spread of germs, it’s important to teach your child to not share anything they use or play with.

2. Getting your child vaccinated against illnesses such as measles and chickenpox is another prevention method. These vaccinations will help protect them from these diseases that have been linked to triggering KD in some cases.

Seek quick medical assistance if you see that your child is exhibiting symptoms that may be KD. A disease’s development and severity can be greatly altered by detecting it early.

While there are no guaranteed ways to prevent Kawasaki Disease completely, practicing good hygiene habits and timely medical treatment can improve outcomes for affected children.


All children, regardless of age, are susceptible to contracting Kawasaki Disease. If your child displays any symptoms of the sickness, it is crucial that you get them checked out very away. Serious problems can often be avoided if the condition is diagnosed and treated early on.

Although the exact cause of Kawasaki disease is still unknown, it is possible to lessen your child’s exposure to it. Promoting health and well-being can be done in many different ways, including by maintaining appropriate hygiene practices, encouraging healthy eating habits, and assuring frequent check-ups with a physician.

As parents, it’s natural to feel anxious when our children fall ill. However, by staying informed about illnesses like Kawasaki Disease and taking preventative measures whenever possible, we can provide our children with the best possible chance at leading happy and healthy lives.
