The pathogenesis of Kawasaki disease is unclear, and the main pathological change is systemic vasculitis. Typically, the rash is a polymorphic erythema or a scarlatiniform rash, primarily occurring on the trunk. Generally, facial rashes are rare, but it's not entirely impossible for rashes to appear on the face. Therefore, if a baby develops a rash on the face without other infections, Kawasaki disease might also present this symptom.

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.

Does Kawasaki disease cause vomiting?

Kawasaki disease is a disease with no clear etiology, commonly seen in infants and toddlers, with eighty percent of cases occurring in children under five years old. Its main pathological change is systemic vasculitis. The main symptoms include fever, congested and cracked lips, diffuse congestion of the oral mucosa, swollen tongue papillae, and strawberry tongue. Other symptoms may include swelling of the hands and feet, polymorphous erythema, and enlarged lymph nodes. There could be subsequent cardiac complications, primarily affecting the coronary arteries. Kawasaki disease may cause vomiting due to the diffuse congestion in the oral cavity, and the pharynx might also be congested. When children experience significant congestion, their laryngeal reflex might be sensitive, possibly leading to vomiting. Furthermore, children with Kawasaki disease might develop secondary infections from other bacteria and viruses, which could also lead to symptoms like vomiting. Therefore, the manifestations of Kawasaki disease can vary, and if significant vomiting occurs, it should be investigated to determine the cause.

Is Kawasaki disease serious?

Kawasaki disease is an etiologically unclear disease with a not well-understood pathogenesis. The principal pathological change involves inflammatory changes in the systemic blood vessels, which can affect the coronary arteries and lead to coronary artery aneurysms and dilation. Kawasaki disease is self-limiting, and most cases resolve well, with recurrences seen in 1-2% of cases. For patients without coronary artery lesions, comprehensive examinations are required 1 month, 3 months, 6 months, and 1-2 years after discharge, including physical examinations, electrocardiograms, and echocardiograms, mainly to assess the heart's condition. If not effectively treated, 15-20% may develop coronary artery aneurysms; such cases need semi-annual or annual medical check-ups. Coronary artery aneurysms often self-resolve within two years post-diagnosis, typically leaving functional abnormalities such as thickening of the vessel wall and reduced elasticity. Major artery aneurysms often do not disappear completely and can lead to thrombosis or narrowing of the vessel lumen. Kawasaki disease is one of the common causes of acquired heart disease in children; therefore, if Kawasaki disease is accompanied by severe coronary damage, it may heal well but could lead to heart disease. If it is not a severe case of Kawasaki disease, timely treatment can still result in a good recovery.

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.

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.
