Summary Summary

Kawasaki disease is a disease that involves inflammation of the blood vessels. It is typically diagnosed in young children, but older children and adults can also develop this condition. Kawasaki disease begins with a fever that lasts at least five days. Other classic symptoms may include red eyes, lips, and mouth; rash; swollen and red hands and feet; and swollen lymph nodes.^[1] Sometimes the disease affects the coronary arteries which carry oxygen-rich blood to the heart, which can lead to serious heart problems. Kawasaki disease occurs most often in people of Asian and Pacific Island descent.^[2] The cause of Kawasaki disease is unknown.^[1]^[2] An infection along with genetic factors may be involved.^[2]^[3] Treatment includes intravenous gamma globulin and high doses of aspirin in a hospital setting.^[1]^[2] Prognosis is generally very good, but in cases of heart complications it depends on the severity of the coronary disease.^[3]

Cause Cause

The cause of Kawasaki disease (KD) is unknown. The disease results when cells move into the tissues and buildup there, leading to vascular damage, but what causes the cell buildup in the first place is unknown. The body's response to a virus or infection combined with genetic factors may cause the disease. However, no specific virus or infection has been identified, and the role of genetics is not well understood.^[2]^[4]

Genetic factors appear to be important to this disorder, as suggested by the increased frequency of the disease in Asian and Asian-American populations and among family members of an affected child. A number of gene variants (polymorphisms) are associated with an increased risk of developing (susceptibility) KD, and some of these variants are also associated with coronary artery lesions and aneurysm formation.[12298]

Other theories suggest that the disease is caused by a response from the body's immune system.^[5]

KD is not contagious; it cannot be passed from one person to another.^[2] Other risk factors include being a male gender, being between six months and five years of age, and having a family history of KD.^[5]

Inheritance Inheritance

A susceptibility to Kawasaki disease (KD) appears to be passed through generations in families, but the inheritance pattern is unknown. Children of parents who have had KD have twice the risk of developing the disease compared to the general population. Children whose siblings have had KD are ten times more likely to develop KD than the general population^[4], but it is still rare for more than one child in a family to develop the disease.^[6]

Treatment Treatment

Intravenous gamma globulin is the standard treatment for Kawasaki disease and is administered in high doses. Children with Kawasaki disease usually improve significantly within 24 hours of treatment with IV gamma globulin (IVIG). Aspirin is often given in combination with the IV gamma globulin as part of the treatment plan in the beginning of the disease.^[1] Additional treatments include glucocorticoids, which may reduce the level of inflammatory markers and fever more rapidly, and decrease the rate of initial treatment failure in certain high-risk patients.^[3] You can read about complications, treatment, and prevention of Kawasaki disease on the American Heart Association website.
