Approximately 3,000 children with Kawasaki disease are hospitalized annually in the United States. The last UK survey was in 1990, whereas current epidemiology, treatment patterns and complication rates are unknown. [114] Various other possible susceptibility genes have been proposed, including polymorphisms in the HLA region, but their significance is disputed. It was thought to be a rare disease which only affected Asian children. Children. Children under 5 years old are most at risk of Kawasaki disease. KD is more common in boys than girls, and the majority of cases are diagnosed in the winte… [14] Coronary artery aneurysms occur as a sequela of the vasculitis in 20–25% of untreated children. Ferri FF. Any use of this site constitutes your agreement to the Terms and Conditions and Privacy Policy linked below. Accessed Sept. 6, 2019. http://www.nhlbi.nih.gov/health/health-topics/topics/kd. Kawasaki disease comes on fast, and symptoms show up in phases. The frequency and ethnic variation of Henoch-Schönlein purpura, Kawasaki disease, and rarer vasculitides during childhood are not well characterised. [3] It is not associated with anti-neutrophil cytoplasmic antibodies, unlike other vasculitic disorders associated with them (such as granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis). However, Kawasaki disease appears to affect Asian children most frequently. This content does not have an English version. [95][96], The specific cause of Kawasaki disease is unknown. [citation needed], Intravenous immunoglobulin (IVIG) is the standard treatment for Kawasaki disease[136] and is administered in high doses with marked improvement usually noted within 24 hours. Accessed Sept. 3, 2019. A single copy of these materials may be reprinted for noncommercial personal use only. It can also affect the blood vessels supplying the heart muscle (coronary arteries). In: Nelson Textbook of Pediatrics. All rights reserved. Kawasaki disease affects boys more than girls, with people of Asian ethnicity, particularly Japanese people. It primarily affects children. Kawasaki disease. It causes a high fever and rash. [58], MI caused by thrombotic occlusion in an aneurysmal, stenotic, or both aneurysmal and stenotic coronary artery is the main cause of death from Kawasaki disease. [83] It can also be found as necrotizing vasculitis, progressing into peripheral gangrene. [3][14] Later, during the convalescent or the subacute phase, desquamation of the fingers and toes usually begins in the periungual region within two to three weeks after the onset of fever and may extend to include the palms and soles. [9] The World Health Organization is examining possible links with COVID-19. [6] Genetic factors are also thought to influence development of coronary artery aneurysms and response to treatment. [14], Even when treated with high-dose IVIG regimens within the first 10 days of illness, 5% of children with Kawasaki disease develop at the least transient coronary artery dilation and 1% develop giant aneurysms. Kawasaki disease affects boys more than girls, with people of Asian ethnicity, particularly Japanese and Korean people, most susceptible, as well as people of Afro-Caribbean ethnicity. Substantial racial and ethnic variation in Kawasaki Disease incidence occurs in the US and worldwide. Three things are known to increase your child's risk of developing Kawasaki disease. [161], In Japan, the rate is 240 in every 100,000 people. [63] Some of these lesions require valve replacement. Coronary artery lesions resulting from Kawasaki disease change dynamically with time. [112] The associated genes and their levels of expression appear to vary among different ethnic groups, both with Asian and non-Asian backgrounds. Accessed Sept. 3, 2019. Echocardiogram may show subtle coronary artery changes or, later, true aneurysms. Our aim was to ascertain the incidence and ethnic distribution of these conditions in children resident in a region of the UK with a diverse ethnic mix. [5] Boys are more commonly affected than girls. [25][26] Iritis can occur, too. Boys are slightly more likely than girls are to develop Kawasaki disease. People of all racial and ethnic groups can get Kawasaki disease, but it is more common in people of Asian descent. Kawasaki disease (KD), also known as Kawasaki syndrome, is a severe illness characterized by inflammation of blood vessels throughout the body that primarily affects young children and infants. [6], In the United States and other developed nations, Kawasaki disease appears to have replaced acute rheumatic fever as the most common cause of acquired heart disease in children. [11] People who have had coronary artery aneurysms after Kawasaki disease require lifelong cardiological monitoring by specialized teams. About 2,000–4,000 cases are identified in the U.S. each year (9 to 19 per 100,000 children younger than five years of age). [3][30] These mouth symptoms are caused by necrotizing microvasculitis with fibrinoid necrosis. Kliegman RM, et al. The inflammation tends to affect the coronary arteries, which supply blood to the heart muscle. If your child has a fever that lasts more than three days, contact your child's doctor. [117][132] A recent, consensus-based evaluation of vasculitides occurring primarily in children resulted in a classification scheme for these disorders, to distinguish them and suggest a more concrete set of diagnostic criteria for each. For a very small percentage of children who develop coronary artery problems, Kawasaki disease can cause death, even with treatment. Within 3 days of the abrupt onset of fever, ... Asian ethnicity. [163] Later, Kawasaki and colleagues were persuaded of definite cardiac involvement when they studied and reported 23 cases, of which 11 (48%) patients had abnormalities detected by an electrocardiogram. [64], Other Kawasaki disease complications have been described, such as aneurysm of other arteries: aortic aneurysm,[65] with a higher number of reported cases involving the abdominal aorta,[66][67] axillary artery aneurysm,[68] brachiocephalic artery aneurysm,[69] aneurysm of iliac and femoral arteries, and renal artery aneurysm. Many cases of myocardial infarction in young adults have now been attributed to Kawasaki disease that went undiagnosed during childhood. described the same illness in 16 children in Hawaii. involving innate rather than adaptive immune pathways). Kawasaki Disease is a multisystem illness with fever and rash, which occurs mainly in children less than 5 years old. [29] The mucosa of the mouth and throat may be bright red, and the tongue may have a typical "strawberry tongue" appearance (marked redness with prominent gustative papillae). [108] These associations are themselves modulated by seasonal and interannual events in the El Niño–Southern Oscillation in winds and sea surface temperatures over the tropical eastern Pacific Ocean.

[6] Winds blowing from central Asia correlate with numbers of new cases of Kawasaki disease in Japan, Hawaii, and San Diego. [6] It does not spread between people. Ethnicity: Children of Asian or Pacific Island descent, such as Japanese or Korean, have higher rates of Kawasaki disease. [58] This can eventually lead to heart muscle tissue death, i.e., myocardial infarction (MI). [14], In the acute phase of the disease, changes in the peripheral extremities can include erythema of the palms and soles, which is often striking with sharp demarcation[14] and often accompanied by painful, brawny edema of the dorsa of the hands or feet, so affected children frequently refuse to hold objects in their hands or to bear weight on their feet. [114], SNPs in FCGR2A, CASP3, BLK, ITPKC, CD40 and ORAI1 have all been linked to susceptibility, prognosis, and risk of developing coronary artery aneurysms.
