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. , Other reported nonspecific symptoms include cough, rhinorrhea, sputum, vomiting, headache, and seizure. , Many risk factors predicting coronary artery aneurysms have been identified, including persistent fever after IVIG therapy, 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. As shown in Table 1, Caucasian children represented 46.7% of KD cases <5 years of age with a reported ethnicity (n= 3751) while 20.1% were Hispanic (n= 1614), 19.2% were African-American (n= 1540), 10.2% were Asian (n= 823), and 3.8% were Other (n= 307).  Since recurrences are unusual in Kawasaki disease, it is thought that the trigger is more likely to be represented by a single pathogen, rather than a range of viral or bacterial agents. It is more common in boys, and in children of North Asian ethnicity, but is seen in all ethnic groups.  This emerging condition was named 'paediatric multisystem inflammatory syndrome' by the Royal College of Paediatrics and Child Health, and 'multisystem inflammatory syndrome in children' by the Centers for Disease Control and Prevention. In the United States and other Western countries, Kawasaki disease occurs in approximately 1 in 10,000 children under 5 each year. In extremely rare cases, Kawasaki disease may occur during adolescence or adulthood. , Kawasaki disease is rare.  Kawasaki disease is now recognized worldwide. , Coronary artery aneurysms due to Kawasaki disease are believed to account for 5% of acute coronary syndrome cases in adults under 40 years of age. 1. , 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.  A plausible explanation is that it may be caused by an infection that triggers an inappropriate immunologic cascade in a small number of genetically predisposed children. Ethnic Kawasaki Disease Risk Associated with Blood Mercury and Cadmium in U.S. Children Deniz Yeter 1,*, Michael A. Portman 2, Michael Aschner 3, Marcelo Farina 4, Wen-Ching Chan 1,5, Kai-Sheng Hsieh 1,6,7 and Ho-Chang Kuo 1,6,7,* Received: 23 November 2015; Accepted: 30 December 2015; Published: 5 …  It can also be found as necrotizing vasculitis, progressing into peripheral gangrene. Book: Mayo Clinic Healthy Heart for Life! Kawasaki disease is not a rare illness and the exact number of cases that occur in the United States has not been determined. 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. Kawasaki Disease Foundation. Coronary artery lesions resulting from Kawasaki disease change dynamically with time.  Diagnosis is usually based on a person's signs and symptoms. It tends to occur more in early spring or winter. 3.  The highest rate of progression to stenosis occurs among those who develop large aneurysms. one commonly associated with excessive immune system activation). It was thought to be a rare disease which only affected Asian children. A single copy of these materials may be reprinted for noncommercial personal use only.  This form of categorization is relevant for appropriate treatment. Currently, Kawasaki disease is the most commonly diagnosed pediatric vasculitis in the world. , For study purposes, including vaccine safety monitoring, an international case definition has been proposed to categorize 'definite' (i.e. 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.  Iritis can occur, too. Kawasaki disease comes on fast, and symptoms show up in phases. , Classically, five days of fever plus four of five diagnostic criteria must be met to establish the diagnosis. McCrindle BW, et al. Kawasaki disease is a syndrome of unknown cause that results in a fever and mainly affects children under 5 years of age. It causes a high fever and rash. Aneurysms increase the risk of blood clots, which could lead to a heart attack or cause life-threatening internal bleeding. ", A further distinction between 'incomplete' and 'atypical' subtypes may also be made in the presence of non-typical symptoms. It can also affect the blood vessels supplying the heart muscle (coronary arteries). complete/incomplete), 'probable' and 'possible' cases of Kawasaki disease.  It can be polymorphic, not itchy, and normally observed up to the fifth day of fever. , Gastrointestinal complications in Kawasaki disease are similar to those observed in Henoch–Schönlein purpura, such as: intestinal obstruction, colon swelling, intestinal ischemia, intestinal pseudo-obstruction, and acute abdomen.  If the coronary arteries are involved, ongoing treatment or surgery may occasionally be required. Kawasaki disease (KD) is one of the most common childhood vasculitides and may lead to coronary arterial complications.  The rash varies over time and is characteristically located on the trunk; it may further spread to involve the face, extremities, and perineum.  Kawasaki disease is also considered to be a primary childhood vasculitis, a disorder associated with vasculitis that mainly affects children under the age of 18. , A relapse of symptoms may occur soon after initial treatment with IVIG. Within 3 days of the abrupt onset of fever, ... Asian ethnicity. , In Japan, the rate is 240 in every 100,000 people. The higher incidence in Asian populations is thought to be linked to genetic susceptibility. Mayo Clinic is a not-for-profit organization. d England-wide hospital admission data for Kawasaki disease in people younger than 18 years of age, during a 5-year period (1998–2003), relating incidence to geographic location, urbanization, deprivation, ethnicity, and to laboratory reports of respiratory virus infection. Children of Asian descent are more likely to have Kawasaki disease. Accessed Sept. 3, 2019.  Efforts have been made to identify a possible pathogen in air-filters flown at altitude above Japan. The absence of reported cases of Kawasaki-like multisystem inflammatory syndrome associated with SARS-CoV-2 infection in Asian countries where the covid-19 pandemic started, and where the incidence of Kawasaki disease is the highest, is noteworthy.38 Ethnic differences in the development of Kawasaki disease shock syndrome were previously reported, with a lower incidence in Asian … Because children with Kawasaki disease will be taking aspirin for up to several months, vaccination against varicella and influenza is required, as these infections are most likely to cause Reye syndrome. , In the acute stage of Kawasaki disease, systemic inflammatory changes are evident in many organs.  According to the diagnostic criteria, at least one impaired lymph node ≥ 15 mm in diameter should be involved. People of all racial and ethnic groups can get Kawasaki disease, but it is more common in people of Asian descent.  Possible explanations could include confusion with other diseases such as scarlet fever, and easier recognition stemming from modern healthcare factors such as the widespread use of antibiotics.  Narrowing of the coronary artery, which occurs as a result of the healing process of the vessel wall, often leads to significant obstruction of the blood vessel and the heart not receiving enough blood and oxygen. . , Other diseases involving necrotizing vasculitis include polyarteritis nodosa, granulomatosis with polyangiitis, Henoch–Schönlein purpura, and eosinophilic granulomatosis with polyangiitis.  With treatment, the risk of death is reduced to 0.17%. Clinical signs of cardiac involvement (arrhythmias, pericardial effusion) Differential Diagnosis. , The course of the disease can be divided into three clinical phases. Elsevier; 2020. https://www.clinicalkey.com. However, with effective treatment, only a few children have lasting damage. The treatment of Kawasaki disease is based on timely administration of …  In 1976, Melish et al. Kawasaki Disease is a multisystem illness with fever and rash, which occurs mainly in children less than 5 years old.
