Kawasaki disease is an autoimmune vasculitis, and since it is vasculitis, it can originate from blood vessels in various parts, including the heart, liver, kidneys, brain, and more. However, it mainly arises from the coronary arteries of the heart.

If Kawasaki disease is not effectively treated, some patients can develop coronary artery dilation and even coronary artery aneurysms. Once a coronary artery aneurysm occurs, its complication includes the risk of rupture and bleeding of the aneurysm, which can be difficult to treat if there is severe bleeding.

If there is some coronary artery dilation, it can lead to the formation of coronary artery thrombosis, which is also a complication it can cause. However, the vast majority of Kawasaki disease cases, if treated effectively, can prevent coronary artery abnormalities. Therefore, as long as the treatment is timely, most cases will not have significant lasting effects.

Is IgE high in Kawasaki disease?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, has an unclear pathogenesis. It is speculated that certain components of infectious sources, such as superantigens, can activate CD30 T cells and CD40 ligand expression directly by binding with T cell antigen receptor fragments without going through mononuclear macrophages. Under the induction of carrier cells, there is polyclonal activation and reduced apoptosis of B08 cells, resulting in the production of large amounts of immunoglobulins such as IgG, IgM, IgA, and IgE, and cytokines. Therefore, the IgE levels in Kawasaki disease are elevated.

Is Kawasaki disease contagious?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, currently has unclear pathogenic mechanisms and the causes of the disease are not well defined. One of its main pathological changes is systemic vasculitis, including the coronary arteries. The disease occurs sporadically or in small epidemics, can happen in any season without clear seasonality, and is generally more common in infants and young children, with eighty percent under five years of age. Kawasaki disease is not a contagious disease, so it does not have significant contagiousness.

Can Kawasaki disease heal itself?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a disease with unclear etiology and unclear pathogenesis. It commonly affects infants and young children, with 80% of cases occurring in children under five years old, and the male to female incidence ratio being 1.5:1. Kawasaki disease is a self-limiting disease, and most cases have a good prognosis. Recurrences are seen in 1%-2% of affected children. Children without coronary artery lesions also need a comprehensive physical examination, generally recommended at one month, three months, six months, and annually or biannually for up to two years, including physical examination, electrocardiogram, and echocardiography. Without effective treatment, 15%-20% of affected children may develop coronary artery aneurysms, and they should be closely followed long-term, with follow-up every six to twelve months. Coronary artery aneurysms often resolve themselves within two years after the disease, but often leave behind abnormalities such as thickened vessel walls and reduced elasticity. Large aneurysms often do not completely resolve and may lead to thrombosis or narrowing of the vessel lumen. Kawasaki disease is also a cause of acquired heart disease, so timely and effective treatment is essential to prevent cardiac issues. Once Kawasaki disease develops, it is advised to seek prompt hospital treatment to manage the condition effectively.

What should be paid attention to in the diet for Kawasaki disease?

Kawasaki disease is a type of mucocutaneous lymph node syndrome, and its main pathological change is systemic vasculitis. Its main characteristics include persistent fever, high fever, ineffective antibiotic treatment, followed by the appearance of a skin rash on the mucous membranes, accompanied by enlarged lymph nodes. When Kawasaki disease occurs, there is a high fever, so it is suggested that children with Kawasaki disease should consume a diet high in protein, calories, and fiber, which is light and easily digestible in liquid or semi-liquid form. Spicy, overly hard, and overly hot foods should be avoided.

How many days does it take to be discharged from the hospital for Kawasaki disease?

Kawasaki disease is a disease with unclear pathogenesis and etiology. A major pathological change is systemic vasculitis, which commonly affects the coronary arteries. Typically, it presents with fever lasting from seven to fourteen days or longer, and antibiotics are ineffective in treatment. During the first through sixth weeks of the illness, complications such as pericarditis, myocarditis, endocarditis, and arrhythmias may occur. Coronary artery damage often occurs between the second and fourth weeks of the illness, and proactive and effective treatment of Kawasaki disease can prevent coronary complications. The acute phase generally involves symptomatic supportive care, prevention of platelet aggregation, fever reduction, and prevention of coronary artery damage. Treatment with intravenous immunoglobulin is recommended within the first ten days of onset. If the treatment is not effective, other special medications like steroids may be used, and the treatment duration is generally between two to four weeks. Thus, the pathogenesis of Kawasaki disease is uncertain, and its pathological process is prolonged. The specific timing of discharge depends on the child's condition. If the fever is controlled and no significant coronary artery damage is evident, and the condition is stable, then discharge is possible. However, post-discharge, follow-up should be conducted based on the child's specific condition. Therefore, the duration of hospitalization for Kawasaki disease is not fixed and depends on the child's condition and treatment response.
