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.

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.

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.

The recurrence rate of Kawasaki disease

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a type of pediatric autoimmune disease that commonly affects infants and young children, especially those under the age of five. The exact mechanisms and causes of the disease are still unclear. The primary pathological change is systemic vasculitis, frequently affecting the coronary arteries. The recurrence rate of Kawasaki disease is between 1%-3%, with a few cases experiencing three or even four occurrences. The interval between recurrences ranges from three months to one year, averaging one year and five months. Studies have shown that being younger than three years old at the time of the first episode and having vascular damage are risk factors for recurrence.

Is Kawasaki disease easy to treat?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a self-limiting disease but is an acute systemic vasculitis commonly seen in infants and children under the age of 5. The primary clinical manifestations include non-suppurative cervical lymphadenopathy, oral mucosal lesions, conjunctival congestion, prolonged fever, polymorphous rash, and hard swelling of the hands and feet with fingertip desquamation. Cardiovascular damage is the most severe complication of Kawasaki disease and can lead to coronary artery aneurysms and coronary artery dilation. If Kawasaki disease is not treated promptly, the incidence of developing coronary artery aneurysms is 15%-25%, making Kawasaki disease one of the most common causes of acquired heart disease in infants and young children. Therefore, timely treatment of Kawasaki disease is crucial, generally involving anti-inflammatory treatment, immune support, and symptomatic management. If there is no concomitant coronary artery damage, treatment involves symptomatic management. If there is coronary artery damage, the treatment duration will be longer and regular follow-up is necessary. The course of the disease can extend over months or even years, thus treatment of Kawasaki disease needs to be tailored based on the individual's condition and clinical symptoms.
