The disease was first described in Japan by Tomisaku Kawasaki in 1967, and the first cases outside of Japan were reported in Hawaii in 1976. [30][48], Some children, especially young infants,[49] have atypical presentations without the classic set of symptoms. Kawasaki disease is a syndrome of unknown cause that results in a fever and mainly affects children under 5 years of age. [127][133] This form of categorization is relevant for appropriate treatment. [3] Many other forms of cutaneous lesions have been reported; they may include scarlatiniform, papular, urticariform, multiform-like erythema, and purpuric lesions; even micropustules were reported. [1] Usually, with treatment, fever resolves within 24 hours and full recovery occurs. 2016 Sep 15;5(9):e003289. Existence of a ‘gut–vascular’ axis…. Apr;59(2):425-45. Fig. [1] Without treatment, coronary artery aneurysms occur in up to 25% and about 1% die. J Am Coll Cardiol. [135][156][157] In the continental United States, Kawasaki disease is more common during the winter and early spring, boys with the disease outnumber girls by ≈1.5–1.7:1, and 76% of affected children are less than years of age. Kawasaki disease: current aspects on … [100], Inflammation, or vasculitis, of the arteries and veins occurs throughout the body, usually caused by increased production of the cells of the immune system to a pathogen, or autoimmunity. [114], SNPs in FCGR2A, CASP3, BLK, ITPKC, CD40 and ORAI1 have all been linked to susceptibility, prognosis, and risk of developing coronary artery aneurysms. [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). Link to abstract. [6] Winds blowing from central Asia correlate with numbers of new cases of Kawasaki disease in Japan, Hawaii, and San Diego. [102] Various explanations exist. [1] Other common symptoms include large lymph nodes in the neck, a rash in the genital area, and red eyes, lips, palms, or soles of the feet. 2004;110:2747–2771. Patient populations based in Asia, people with higher risk scores, and those receiving longer steroid treatment may have greater benefit from steroid use. The higher incidence in Asian populations is thought to be linked to genetic susceptibility. COVID-19 is an emerging, rapidly evolving situation.

Adipokines and Inflammation: Focus on Cardiovascular Diseases. [14][15] This is the most prominent symptom of Kawasaki disease, and is a characteristic sign that the disease is in its acute phase; the fever normally presents as a high (above 39–40 Â°C) and remittent, and is followed by extreme irritability. 2020 Sep 21;31(Suppl 2):268-274. doi: 10.31138/mjr.31.3.268. [3][30] These mouth symptoms are caused by necrotizing microvasculitis with fibrinoid necrosis. Kawasaki disease is an acute multisystem inflammatory disease of blood vessels (vasculitis) that most commonly affects infants and young children. Fig. Other names for it are Kawasaki syndrome and mucocutaneous lymph node syndrome. the patient will recover eventually), but the risk of coronary artery involvement is much greater, even many years later. [110] One source has been suggested in northeastern China. [117] Within this classification of childhood vasculitides, Kawasaki disease is, again, a predominantly medium-sized vessel vasculitis. Kawasaki disease is predominantly a disease of young children, with 80% of patients younger than five years of age. Toxic shock syndrome 5. [95][96], The specific cause of Kawasaki disease is unknown. 4. [112] The associated genes and their levels of expression appear to vary among different ethnic groups, both with Asian and non-Asian backgrounds. Kawasaki disease is a syndrome of unknown cause that results in a fever and mainly affects children under 5 years of age. [51] It is first detected at a mean of 10 days of illness and the peak frequency of coronary artery dilation or aneurysms occurs within four weeks of onset. Currently, Kawasaki disease is the most commonly diagnosed pediatric vasculitis in the world. 1. The clinical features of KD including fever, rash, mucosal changes, conjunctival erythema, and cervical lymphadenopathy are all compatible with an infectious illness, and many common … [38] The rash varies over time and is characteristically located on the trunk; it may further spread to involve the face, extremities, and perineum. [127] Systemic vasculitides may be classified according to the type of cells involved in the proliferation, as well as the specific type of tissue damage occurring within the vein or arterial walls. Histological and morphological findings in the LCWE-induced mouse model of Kawasaki disease vasculitis. Histological and morphological findings in…. 2020 Oct 18;21(20):7711. doi: 10.3390/ijms21207711. Report from the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease in the Young, American Heart Association", "Long-term consequences of Kawasaki disease. [107], Seasonal trends in the appearance of new cases of Kawasaki disease have been linked to tropospheric wind patterns, which suggests wind-borne transport of something capable of triggering an immunologic cascade when inhaled by genetically susceptible children. [46], Adult onset of Kawasaki disease is rare. Despite the prominent mucocutaneous clinical findings that define the illness, Kawasaki disease is best regarded as a generalized vasculitis that involves small- to medium-sized arteries. [63] Some of these lesions require valve replacement. Friedman KG, Gauvreau K, Hamaoka-Okamoto A, Tang A, Berry E, Tremoulet AH, Mahavadi VS, Baker A, deFerranti SD, Fulton DR, Burns JC, Newburger JW. Many other serious illnesses can cause similar symptoms, and must be considered in the differential diagnosis, including scarlet fever, toxic shock syndrome, juvenile idiopathic arthritis, and childhood mercury poisoning (infantile acrodynia). It primarily affects children. Some genes are susceptible to create the condition for Kawasaki Disease. -, Newburger JW, et al. Kawasaki disease causes inflammation in the walls of medium-sized arteries throughout the body. [74], Gastrointestinal complications in Kawasaki disease are similar to those observed in Henoch–Schönlein purpura,[68] such as: intestinal obstruction,[75] colon swelling,[76] intestinal ischemia,[77] intestinal pseudo-obstruction,[78] and acute abdomen. [7], Based on clinical findings, a diagnostic distinction may be made between the 'classic' / 'typical' presentation of Kawasaki disease and 'incomplete' / 'atypical' presentation of a "suspected" form of the disease. Education Gap. [3] However, when appropriate therapy is started â€“ intravenous immunoglobulin and aspirin â€“ the fever subsides after two days. [60] Most of these children had the attack occurring during sleep or at rest, and around one-third of attacks were asymptomatic. [164] In 1974, the first description of this disorder was published in the English-language literature. Kawasaki disease.,PediatrClin North Am. The inflammation of Kawasaki disease can damage a child’s coronary arteries, which carry blood to their heart. [28][31] According to the diagnostic criteria, at least one impaired lymph node ≥ 15 mm in diameter should be involved. Kawasaki disease is an acute systemic vasculitis of unknown etiology that has become the most common form of acquired heart disease in young children in developing countries. Arch Dis Child. [35] Around 11% of children affected by the disease may continue skin-peeling for many years. [90] Other neurological complications from cranial nerve involvement are reported as ataxia,[68] facial palsy,[92] and sensorineural hearing loss. [6][126] Identification of the exact nature of the immune process involved in Kawasaki disease could help guide research aimed at improving clinical management. Kawasaki disease (KD), or mucocutaneous lymph node syndrome, is an illness that causes inflammation in arteries, veins, and capillaries. [14], Many risk factors predicting coronary artery aneurysms have been identified,[20] including persistent fever after IVIG therapy,[55][56] low hemoglobin concentrations, low albumin concentrations, high white-blood-cell count, high band count, high CRP concentrations, male sex, and age less than one year. [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. In Kawasaki disease, necrotizing arteritis develops in the first 2 weeks of the disease and is associated with neutrophilic infiltration, which gradually destroys the intima, media and some portions of the adventitia of the coronary artery. Dr. Kawasaki died on June 5, 2020 at the age of 95. Biopsy is rarely performed, as it is not necessary for diagnosis. This new condition also causes symptoms of shock, … Kawasaki disease is also called mucocutaneous lymph node syndrome because it also affects lymph nodes, skin, and the mucous … Although the vascular inflammation is most pronounced in the coronary vessels, vasculitis can also occur in veins, capillaries, small arterioles, and larger arteries. [104] Various candidates have been implicated, including upper respiratory tract infection by some novel RNA virus. Here, we outline the pathophysiology of Kawasaki disease and summarize and discuss the progress gained from experimental mouse models and their potential therapeutic translation to human disease. [3] Prolonged fever is associated with a higher incidence of cardiac involvement. IVIG by is most useful within the first seven days of fever onset, to prevent coronary artery aneurysm. Except for Kawasaki disease and a few other indications, aspirin is otherwise normally not recommended for children due to its association with Reye syndrome. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. Untreated, the acute symptoms of Kawasaki disease are self-limited (i.e. [70] In addition, children with Kawasaki disease, with or without coronary artery complications, may have a more adverse cardiovascular risk profile,[73] such as high blood pressure, obesity, and abnormal serum lipid profile. The children who develop Kawasaki disease may be genetically predisposed to it. At this present attack rate, more than one in 150 children in Japan will develop Kawasaki disease during their lifetimes. Clipboard, Search History, and several other advanced features are temporarily unavailable. [27] Keratic precipitates are another eye manifestation (detectable by a slit lamp, but are usually too small to be seen by the unaided eye). [36] One to two months after the onset of fever, deep transverse grooves across the nails may develop (Beau's lines),[37] and occasionally nails are shed. Kawasaki disease. In healthy individuals, intestinal epithelial cells are sealed together by intestinal tight junctions, and the intestinal epithelium acts as a barrier that prevents the passage of commensal bacteria and pathogens while permitting intercellular flux of ions, molecules and metabolites. R01 AI072726/AI/NIAID NIH HHS/United States, R01 HL139766/HL/NHLBI NIH HHS/United States, Kawasaki T, Kosaki F, Okawa S, Shigematsu I, Yanagawa H. A new infantile acute febrile mucocutaneous lymph node syndrome (MLNS) prevailing in Japan. [114] Various other possible susceptibility genes have been proposed, including polymorphisms in the HLA region, but their significance is disputed. Kawasaki disease is the leading cause of acquired heart disease among children in the USA. [83] It can also be found as necrotizing vasculitis, progressing into peripheral gangrene. By far, the highest incidence of Kawasaki disease occurs in Japan, with the most recent study placing the attack rate at 218.6 per 100,000 children less than five years of age (about one in 450 children). [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. Pediatrics. [114], Since no specific laboratory test exists for Kawasaki disease, diagnosis must be based on clinical signs and symptoms, together with laboratory findings. 2017;135:e927–e999. [1] If the coronary arteries are involved, ongoing treatment or surgery may occasionally be required. [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. [52][53][54] Death can occur either due to myocardial infarction secondary to blood clot formation in a coronary artery aneurysm or to rupture of a large coronary artery aneurysm. IVIG given within the first 10 days of the disease reduces the risk of damage to the coronary arteries in children, without serious adverse effects. [138] Aspirin therapy is started at high doses until the fever subsides, and then is continued at a low dose when the patient returns home, usually for two months to prevent blood clots from forming. [30] Saccular and fusiform aneurysms usually develop between 18 and 25 days after the onset of illness. [167], A question was raised whether the disease only started during the period between 1960 and 1970, but later a preserved heart of a seven-year-old boy who died in 1870 was examined and showed three aneurysms of the coronary arteries with clots, as well as pathologic changes consistent with Kawasaki disease. NIH [136], Salicylate therapy, particularly aspirin, remains an important part of the treatment (though questioned by some)[137] but salicylates alone are not as effective as IVIG. [14] Coronary artery aneurysms occur as a sequela of the vasculitis in 20–25% of untreated children. [1] The disorder is named after Japanese pediatrician Tomisaku Kawasaki, who first described it in 1967. -, Newburger JW, Takahashi M, Burns JC. 3. Overall, life-threatening complications resulting from therapy for Kawasaki disease are exceedingly rare, especially compared with the risk of nontreatment. [117], It can also be classed as an autoimmune form of vasculitis. This vasculitis has a predilection for coronary arteries with a high complication rate across the lifespan for those with medium to large coronary artery aneurysms. It is not contagious. [46], For study purposes, including vaccine safety monitoring, an international case definition has been proposed to categorize 'definite' (i.e. It causes a high fever and rash. [59] The highest rate of progression to stenosis occurs among those who develop large aneurysms. [6] Genetic factors are also thought to influence development of coronary artery aneurysms and response to treatment. Am. [11] People who have had coronary artery aneurysms after Kawasaki disease require lifelong cardiological monitoring by specialized teams. Kawasaki disease causes the blood vessels to become inflamed and swollen, which can lead to complications in the blood vessels that supply blood to the heart (coronary arteries). [139], High-dose aspirin is associated with anemia and does not confer benefit to disease outcomes. 1. The authors declare no competing interests. It is a form of vasculitis, where blood vessels become inflamed throughout the body. DOI: 10.1161/CIR.0000000000000484 April 25, 2017 follow-up, with recurrences occurring at a median of 1.5 [6] Regarding 'incomplete' / 'atypical' presentation, American Heart Association guidelines state that Kawasaki disease "should be considered in the differential diagnosis of prolonged unexplained fever in childhood associated with any of the principal clinical features of the disease, and the diagnosis can be considered confirmed when coronary artery aneurysms are identified in such patients by echocardiography. Circulation. Also read about multisystem inflammatory syndrome in children (MIS-C), a disease similar to Kawasaki disease but linked to … [42] Joint pain (arthralgia) and swelling, frequently symmetrical, and arthritis can also occur. Source: Nelson's essentials of pediatrics, swelling or erythema of the hands or feet, swollen lymph node in the neck of at least 15 mm. One theory is that rather than there being a single gene responsible for Kawasaki disease, it may be the result of many genes that each slightly … [143] Additionally, corticosteroid use in the setting of Kawasaki disease is associated with increased risk of coronary artery aneurysm, so its use is generally contraindicated in this setting. Epub 2016 Apr 11. 2016 May;48:70-5. doi: 10.1016/j.cct.2016.04.002. [20] It responds partially to antipyretic drugs and does not cease with the introduction of antibiotics. Child. If the fever does not respond, an additional dose may be considered. Abstract. Kawasaki Disease (KD) vasculopathy, which most significantly affects the coronary arteries, is characterized by three linked pathological processes: necrotizing arteritis, subacute/chronic (SA/C) vasculitis, and luminal myofibroblastic proliferation (LMP). Crit Care Explor. Coronary Artery Aneurysms in Kawasaki Disease: Risk Factors for Progressive Disease and Adverse Cardiac Events in the US Population. [47] Aneurysms are classified into small (internal diameter of vessel wall <5 mm), medium (diameter ranging from 5–8 mm), and giant (diameter > 8 mm). [5] Boys are more commonly affected than girls. [30] In developed nations, it appears to have replaced acute rheumatic fever as the most common cause of acquired heart disease in children.
