Kawasaki disease


How long does Kawasaki disease require hospitalization?
Kawasaki disease requires hospitalization and continued medication after discharge. The duration of the hospital stay is mainly determined by the child's clinical symptoms. The child can return home when the fever subsides and the dosage of aspirin is reduced, which may take about four to seven days, although this is just a general scenario. After discharge, medication must continue. If the child's coronary arteries are fine, with no dilation or lesions, a low dose of aspirin can be taken for about two months. If there are issues with the coronary arteries, aspirin must be continuously taken until the dilation resolves before stopping the aspirin, so this period can be quite long.


Kawasaki disease sequelae
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 Kawasaki disease prone to recurrence?
Kawasaki disease is a common pediatric febrile, rash-causing illness, and once diagnosed, treatment must begin actively. Most cases of Kawasaki disease have a very good prognosis with standard treatment, but about 5% of children may experience temporary coronary artery abnormalities, and the recurrence rate of Kawasaki disease can reach 1% to 3%. Therefore, once a child is diagnosed with Kawasaki disease, it is essential to conduct follow-up throughout the treatment process. Follow-ups should be done at three months, six months, and one year after the onset of the disease in new cases. The purpose of the follow-up is mainly to assess the child's prognosis and evaluate the coronary arteries to see if there is any recurrence, so this follow-up work is very important.


How is Kawasaki disease treated?
Kawasaki disease, also known as mucocutaneous lymph node syndrome, can cause damage to the coronary arteries in untreated children, so it is crucial to treat the disease promptly once diagnosed. This disease generally occurs sporadically or in small outbreaks and can occur in any season, predominantly affecting infants and young children. The main treatment for Kawasaki disease is aspirin, which not only reduces fever but also helps reduce coronary artery lesions. Additionally, intravenous immunoglobulin is administered; however, the use of corticosteroids in Kawasaki disease is still somewhat controversial. Other treatments mainly include antiplatelet aggregation agents such as dipyridamole, and symptomatic supportive care for the child, including fluid supplementation, heart protection, control of heart failure, and correction of arrhythmias. For severe coronary artery lesions, coronary artery bypass surgery may be required. (Please use medication under the guidance of a professional physician.)


Is it normal for Kawasaki disease to have a lower temperature?
The etiology of Kawasaki disease is currently unclear; its primary pathological feature is systemic vascular inflammation. Kawasaki disease typically presents with fever, high fevers ranging from 39 to 40 degrees Celsius. If a patient with Kawasaki disease has a lower temperature, it may indicate that the condition is quite severe. For example, children generally have weaker immune systems, or if they have a severe co-infection, hypothermia may occur. In this case, it is recommended that doctors perform further examinations and intensify treatment. Therefore, a lower temperature in Kawasaki disease is also abnormal. Normally, the body temperature should gradually return to the normal range, and both hypothermia and hyperthermia are definitely abnormal conditions.


Does Kawasaki disease rash itch?
Kawasaki disease, once called mucocutaneous lymph node syndrome, is a disease of unknown cause and unclear pathogenesis. It is characterized by systemic vasculitis. Clinically, it mainly presents with fever, conjunctival congestion, cracked lips, congested oral mucosa, diffuse congestion, strawberry tongue, acute stage swelling and erythema of the hands and feet, polymorphous rash, and scarlet fever-like skin rash. It is often associated with unilateral or bilateral lymphadenopathy, which is not red on the surface, but the lymph nodes are hard and tender to the touch. It frequently involves complications such as myocarditis or pericarditis, with common coronary artery damage. The rash seen in Kawasaki disease is a manifestation of vasculitis and is generally non-itchy.


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 can Kawasaki disease be cured?
Kawasaki disease is a syndrome of mucocutaneous lymph node syndrome, the cause of which is unclear, as is the pathogenesis of the disease. The pathological changes are mainly systemic vasculitis, which is prone to secondary damage to the coronary arteries. It has a relatively long course. If fever occurs, the fever can persist for 1-2 weeks. Generally, special medications such as aspirin are required for treatment. Usually, treatment is for 3 days, and after the fever subsides, the dosage is gradually reduced, maintained for 6-8 weeks. If there is secondary coronary artery damage, the duration might be longer. In cases of severe coronary damage, the duration of the disease may be several months or even years, depending on the specific condition of the disease. Kawasaki disease is a self-limiting disease. Usually, if there is no significant coronary artery damage, after symptom control, comprehensive examinations are conducted 1 month, 3 months, 6 months, and 1-2 years after discharge, mainly heart examinations such as electrocardiograms and echocardiograms. If there is a combination of coronary artery aneurysms, long-term follow-up is required, with an examination every six months to one year until the coronary aneurysm disappears or if there is combined damage to the coronary artery structure, long-term follow-up is needed.


How long does it take to cure Kawasaki disease?
Kawasaki disease, also known as mucocutaneous lymph node syndrome, has unclear etiology and pathogenesis. The primary pathological change is systemic vasculitis, frequently affecting the coronary arteries. Kawasaki disease is considered a self-limiting condition, with most cases having a good prognosis; recurrence occurs in 1% to 2% of affected children. If associated with coronary artery damage and not effectively treated, 15% to 25% of these cases can develop coronary artery aneurysms. Typically, coronary artery aneurysms resolve within two years of onset, but often leave residual arterial wall thickening and reduced elasticity. Large aneurysms do not disappear completely and can lead to thrombosis or stenosis. Kawasaki disease is also one of the main causes of acquired heart disease in children. Therefore, active and effective treatment of Kawasaki disease can result in recovery. However, if there is accompanying coronary artery damage, the prognosis can vary depending on the extent of the damage. Severe coronary artery damage might lead to long-term heart disease.


How long to take aspirin for Kawasaki disease
The current pathogenesis of Kawasaki disease is not yet clear, but one of its main pathological changes is a systemic vasculitis. During an outbreak of Kawasaki disease, the blood viscosity increases primarily due to platelet aggregation. Typically, oral aspirin is administered to prevent this inflammation and to treat platelet aggregation. The dosage is generally reduced gradually once the fever subsides, with maintenance doses lasting about six to eight weeks. If coronary artery lesions are present, the duration of medication is extended until the coronary arteries return to normal before discontinuing the drug.
