Kawasaki disease (KD) is a rare childhood illness causing inflamed blood vessels (vasculitis), especially the coronary arteries, leading to fever, rash, red eyes, swollen glands, and red, cracked lips, often mimicking other illnesses like measles or scarlet fever, making prompt diagnosis crucial to prevent heart damage, says this {Link: Royal Australian College of General Practitioners (RACGP), this {Link: Royal Children's Hospital (RCH), this {Link: Murdoch Childrens Research Institute (MCRI) and this {Link: Cleveland Clinic article}. It's the leading cause of acquired heart disease in children in developed nations, requiring urgent treatment with immunoglobulin and aspirin to reduce risks like coronary artery aneurysms (bulges).
What is Kawasaki disease? Kawasaki disease is a rare illness that usually affects small children. Other names for the disease are Kawasaki syndrome and mucocutaneous lymph node syndrome. It is a type of vasculitis, which is inflammation of the blood vessels.
Kawasaki disease is an emergency. If your child is showing symptoms of Kawasaki disease or a related condition called multisystem inflammatory syndrome in children (MIS-C), call 911 or go to the nearest emergency room.
Sometimes children with Kawasaki disease see doctors with special training in heart conditions, bone and joint disorders, or infectious diseases. A doctor who treats children with heart conditions is called a pediatric cardiologist. A rheumatologist treats children with bone and joint disorders.
Kawasaki disease causes the blood vessels to become inflamed and swollen, which can lead to complications in the blood vessels that supply blood to the heart (coronary arteries). Without treatment, around 1 in 4 children with Kawasaki disease get heart complications. This can be fatal in about 2 to 3% of cases.
The exact cause of Kawasaki disease is unknown, but it's believed to stem from a child's immune system overreacting to an infection (viral or bacterial) in genetically susceptible individuals, leading to widespread blood vessel inflammation (vasculitis), especially in the coronary arteries; it's not contagious but tends to occur seasonally and is more common in certain ethnicities and boys.
A predisposition to Kawasaki disease appears to be passed through generations in families, but the inheritance pattern is unknown. Children of parents who have had Kawasaki disease have twice the risk of developing the disorder compared to the general population.
Treatment for Kawasaki Disease
Children are usually admitted to the hospital for two to five days. Treatment includes intravenous gamma globulin (IVIG), which is an infusion through your child's IV and high-dose aspirin every six hours. These medicines help reduce the swelling and inflammation in the blood vessels.
Overview. Kawasaki disease (KD), also known as Kawasaki syndrome, is a disease that can cause damage to the heart and blood vessels, mostly in children younger than 5 years old. It affects boys more often than girls. The cause of KD is not known.
Some recent reports have shown that COVID-19 is associated with the appearance of cases of Kawasaki-like disease (KLD), particularly in children. To our knowledge, the following is one of the first cases describing a severe form of KLD in a young adult that was probably secondary to COVID-19.
As Kawasaki disease isn't contagious, it can't be passed from one person to another. This makes it unlikely that it's caused by a virus alone. Kawasaki disease can affect children of any age. It can be more serious in children under the age of 1.
Kawasaki disease is treated in hospital as it can cause serious complications. Treatment should begin as soon as possible. It may take longer for your child to recover if Kawasaki disease isn't treated promptly. Their risk of developing complications will also be increased.
Neurological involvement in Kawasaki disease (KD) is rare and ranges from mild to severe, occasionally leading to fatal outcomes and poor prognosis. However, its impact on clinical outcomes, particularly coronary artery involvement, remains unclear.
Kawasaki disease is a rare heart condition that causes a high fever and inflammation of the blood vessels. It usually affects children under the age of 5. It is the most common form of acquired (not present at birth) heart disease in children in developed countries.
Diseases with features that are similar to Kawasaki disease include: Viral infections such as rubeola, roseola, rubella, adenovirus, and others. Bacterial infections such as streptococcal scarlet fever, staphylococcal scalded skin syndrome, toxic shock syndrome, and mycoplasma infection.
Kawasaki disease has telltale symptoms and signs that appear in phases. The first phase, which can last for up to 2 weeks, usually involves a fever that lasts for at least 5 days. Other symptoms include: red ("bloodshot") eyes.
The exact cause of Kawasaki disease is unknown, but it's believed to stem from a child's immune system overreacting to an infection (viral or bacterial) in genetically susceptible individuals, leading to widespread blood vessel inflammation (vasculitis), especially in the coronary arteries; it's not contagious but tends to occur seasonally and is more common in certain ethnicities and boys.
The outlook for children with Kawasaki disease depends on how much it affects their hearts. Complications that affect their heart can be severe enough to be fatal within 15 to 45 days of a fever starting. Fortunately, treatment can usually keep heart disease from occurring.
New evidence strongly suggests that Kawasaki disease is caused by a single, unidentified respiratory virus, not multiple pathogens or toxins. Inclusion bodies, indicators of viral infection, were found in every examined tissue sample from both the U.S. and Japan over 50 years.
Your child's hands and feet may swell up, and the skin on their hands and feet may become red or hard. Your child may feel their hands and feet are tender and painful to touch or put weight on, so they may be reluctant to walk or crawl while these symptoms persist.
With prompt treatment, most children with Kawasaki disease make a full recovery. But sometimes complications can develop. The complications associated with Kawasaki disease are mainly related to the heart. They happen as a result of the inflammatory effect that the condition has on the blood vessels.
In April, researchers in the UK and several European countries with high numbers of COVID-19 cases recognised a new inflammatory syndrome in children that was similar to Kawasaki disease, a rare syndrome known to affect young children.
Rarely, Kawasaki Disease can reoccur months to years after the initial disease (in Japan, recurrences have been reported in only 4.3% of all cases). Should the signs and symptoms described earlier in this pamphlet reoccur, call your doctor immediately.
Kawasaki's origins go back to 1878, when Shozo Kawasaki established Kawasaki Tsukiji Shipyard in Tokyo. Eighteen years later, in 1896, it was incorporated as Kawasaki Dockyard Co., Ltd.
