Kawasaki disease
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 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.
Why do children get Kawasaki disease?
Kawasaki disease has an unclear pathogenesis. It is speculated that it may be related to infections by microorganisms or other pathogens, familial genetic susceptibility, or autoimmune functions. Currently, the entire medical history is unclear, and there is no specific epidemiology identified for the onset of the disease; it can occur in any of the four seasons. The disease primarily affects infants and young children, with about 80% of cases occurring in children under five years of age. The ratio of male to female incidence is approximately 1.5:1. Thus, Kawasaki disease is most commonly seen in infants and young children. Currently, there is no definitive explanation for the mechanism of the disease.
Can Kawasaki disease be cured?
Kawasaki disease, also known as mucocutaneous lymph node syndrome, has an unclear pathogenesis. The primary pathological change is systemic vasculitis. It commonly affects infants and young children, with 80% of cases occurring in children under five years of age. Kawasaki disease is a self-limiting condition, and most cases have a good prognosis. However, there is a 1% to 2% chance of recurrence. If not effectively treated, 15% to 25% of cases may develop coronary artery aneurysms. These aneurysms often resolve on their own within two years after the disease, but often leave behind abnormalities such as thickening of the vessel wall and decreased elasticity. Larger aneurysms may not completely resolve and can lead to thrombosis or narrowing of the vessel. Kawasaki disease is also one of the causes of acquired heart disease in children. Therefore, Kawasaki disease should be treated promptly and effectively to prevent severe complications.
Does Kawasaki disease cause a rash on the face?
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.
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.
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.
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.
What is Kawasaki Disease?
Kawasaki disease was first reported in 1967 by Tomisaku Kawasaki in Japan and is also known as mucocutaneous lymph node syndrome. Approximately 15% to 20% of cases experience coronary artery damage after effective treatment. Since 1970, cases have been reported worldwide, with a higher incidence among Asians. As diagnostic capabilities improve globally, the incidence of this disease is decreasing. This disease occurs sporadically or in small epidemics and can occur in any season, most commonly affecting infants and young children, with 80% of cases occurring in children under five years of age. The cause of the disease is unclear, and the mechanism of onset is also not well understood, with the primary pathological change being systemic vasculitis. The main clinical symptoms are high fever between 39 to 40 degrees Celsius, followed by ineffectiveness of antibiotic treatment, and conjunctival congestion. Other symptoms include congested, cracked lips, diffuse congestion of the oral mucosa, indurative edema of hands and feet with emerging erythema, polymorphous skin eruptions and scarlet fever-like rash, and enlarged cervical lymph nodes, which can be unilateral or bilateral, hard and tender, but not red on the surface. There may be complications involving coronary artery damage, and potential complications such as myocarditis, pericarditis, endocarditis, and arrhythmias. Additionally, there may be other associated symptoms such as interstitial pneumonia, digestive system symptoms, joint pain, and arthritis.
