The general follow-up schedule for Kawasaki disease starts at discharge. If no coronary artery dilation or coronary aneurysms are found, follow-ups typically occur one month, three months, six months, and twelve months after discharge and include echocardiography and electrocardiograms. If there are coronary artery abnormalities, the echocardiography and electrocardiograms will continue until the coronary arteries return to normal. Even if they normalize early, follow-ups should continue until the age of two.

Kawasaki Disease Aspirin Side Effects

Aspirin is necessary for Kawasaki disease. Considering the pros and cons, aspirin must be used in cases of Kawasaki disease, initially in high doses. However, aspirin indeed has side effects. Some say aspirin is contraindicated for children, as its consumption can lead to Reye's Syndrome. This syndrome involves widespread mitochondrial damage following the intake of salicylate drugs during viral infection recovery, posing risks to the liver and brain. Without timely treatment, it could likely lead to liver and kidney failure, brain damage, or even death. Thus, aside from specific diseases, the use of aspirin is strictly prohibited. These specific diseases include Kawasaki disease, rheumatoid arthritis, etc. Therefore, the use of aspirin in Kawasaki disease is necessary, but it can indeed lead to some side effects.

How to alleviate vomiting in Kawasaki disease

When children with Kawasaki disease experience vomiting, the first step is to refrain from eating and drinking, including water, for one to two hours after vomiting to avoid burdening the stomach and intestines. If vomiting subsides after fasting, there is no need for medication temporarily. However, if there is no significant relief and bloating is evident, it is necessary to treat for bowel movement and gas release. At this time, oral medications that aid in digestion, such as digestive tonics, are acceptable. If relief is still not achieved, intravenous fluid supplementation and medications that enhance gastrointestinal motility can be administered. Parents can also keep the abdomen warm and, centering around the navel, perform clockwise abdominal massages to help alleviate the symptoms of vomiting.

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.

Is Kawasaki disease scary?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a common pediatric autoimmune disease. The pathogenesis of Kawasaki disease remains unclear, and its etiology is also unknown, mainly focusing on immune reactions, genetic susceptibility, and theories of pathogenic microbial infections. Its primary pathological change is systemic vasculitis, most commonly affecting the coronary arteries. Most cases of Kawasaki disease have a good prognosis, with recurrences seen in 1% to 2% of patients. After effective treatment, complications involving coronary artery damage are less common. However, untreated patients develop coronary artery aneurysms in 15%-25% of cases. These aneurysms often resolve on their own within two years of the illness, but often leave behind complications such as thickened vessel walls and reduced elasticity. Large aneurysms are less likely to resolve completely and often lead to thrombosis or narrowing of the vessel lumen. Kawasaki disease is also one of the common causes of acquired heart disease in children. Thus, if Kawasaki disease is detected early, timely treatment is necessary to avoid cardiac sequelae. After effective treatment, the prognosis is generally good. However, if there are complications like coronary artery damage or other heart issues, it may affect the child's quality of life and even lifespan.

Is the spirit of Kawasaki disease good?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, has an unclear cause and is generally prevalent in infants and young children, with 80% of cases occurring in children under five years old. The mechanism of the disease is also not very clear. Its main pathological presentation is systemic vasculitis, often involving the coronary arteries. The primary clinical symptoms include high fever, which is unresponsive to antibiotic treatment, conjunctival congestion, diffuse oral congestion, strawberry tongue, indurative edema of the hands and feet, and palmoplantar erythema. Additionally, it may affect the heart, leading to conditions such as pericarditis, myocarditis, endocarditis, and arrhythmias. During the acute phase of Kawasaki disease, the high fever and diffuse oral mucosal congestion can affect the child's mental state. If the heart is involved, there may be abnormalities in heart rate and heart function, which can also lead to a poor mental state. Therefore, if Kawasaki disease is confirmed, it definitely requires active treatment.
