Stress tests with myocardial perfusion evaluation may be useful in the second decade to guide recommendations for physical activity. Background. Because of the imperfect performance of scoring systems, all patients who are diagnosed with Kawasaki disease should be treated with IVIG. Studies should be recorded in a dynamic video or digital cine format, because the normal translational movement of the heart facilitates the display of the coronary artery anatomy. After the early symptoms go away, follow up with your child’s doctor to be sure their heart is working the way it should. Clinical experience with Kawasaki disease permits the stratification of patients according to their relative risk of myocardial ischemia. An echocardiogram can show many of these complications. Methods and Results. In children who undergo lumbar puncture, ∼50% demonstrate evidence of aseptic meningitis with a predominance of mononuclear cells, as well as normal glucose and protein levels.81. Kawasaki disease is an acute self-limited vasculitis of childhood that is characterized by fever, bilateral nonexudative conjunctivitis, erythema of the lips and oral mucosa, changes in the extremities, rash, and cervical lymphadenopathy. Since no specific laboratory test exists for Kawasaki disease, diagnosis must be based on clinical signs and symptoms, together with laboratory findings. Collision or high-impact sports should be discouraged because of the risk of bleeding. Inflammation of blood vessels (vasculitis), usually the coronary arteries, that supply blood to the heart 2. Some adult patients may be unable to recall an illness that occurred so early in life, however. The conventional diagnostic criteria should be viewed as guidelines that are particularly useful in preventing overdiagnosis but may result in failure to recognize incomplete forms of illness. Consider alternative diagnoses (see Table 2). An attractive hypothesis is that Kawasaki disease is caused by a ubiquitous infectious agent that produces clinically apparent disease only in certain genetically predisposed individuals, particularly Asians. Adjunctive therapy with warfarin with a target INR of 2.0:2.5 is recommended for patients with giant aneurysms. The risk factors that Beiser and associates used in the sequential classification instrument included baseline neutrophil and band counts, hemoglobin concentration, platelet count, and temperature on the day after IVIG infusion. Although the echocardiographic examination of patients with Kawasaki disease is focused on the coronary arteries, other information can and should be obtained. Late cardiac sequelae of Kawasaki disease may first manifest in adulthood.221,222 A history of a Kawasaki disease-like illness in childhood should be sought in patients who present with coronary aneurysms in the absence of generalized atherosclerotic disease. More than 4,200 U.S. children are diagnosed with Kawasaki disease each year. Echocardiography also may be useful in evaluating children with protracted fever and some features of Kawasaki disease. For uncomplicated cases, echocardiographic evaluation should be performed at the time of diagnosis, at 2 weeks, and at 6 to 8 weeks after onset of the disease. Patients who have undergone surgical revascularization or catheter intervention may have a repeat cardiac catheterization so that the efficacy of the treatment can be evaluated (evidence level C). Kawasaki disease is a rare condition that involves inflammation of the blood vessels. In addition, the visualization of coronary arteries becomes progressively more difficult as a child grows and body size increases. Cardiac catheterization with selective coronary angiography is recommended to address the therapeutic options of bypass grafting or catheter intervention and to identify the extent of collateral perfusion. The phrase “atypical Kawasaki disease” should be reserved for patients who have a problem, such as renal impairment, that generally is not seen in Kawasaki disease. Surgical management in Kawasaki disease comprises primarily coronary artery bypass grafts for obstructive lesions.201–203 The diameter and length of internal mammary grafts increase with the somatic growth of children as compared with the tendency of saphenous vein grafts to shorten somewhat over time. Kawasaki disease - an acute disease of young children characterized by a rash and swollen lymph nodes and fever; of unknown cause mucocutaneous... Infantile polyarteritis - definition of Infantile polyarteritis by The Free Dictionary Additional severe abnormalities of coronary flow may arise over time secondary to incremental stenoses at the proximal or distal or proximal and distal ends of the aneurysm. Practices regarding the duration of high-dose aspirin administration vary across institutions, and many centers reduce the aspirin dose after the child has been afebrile for 48 to 72 hours. The patient should be monitored for known risk factors of atherosclerosis and his or her family should be counseled accordingly. Progressive stenosis in the disease results from active remodeling with intimal proliferation and neoangiogenesis; the intima is markedly thickened and consists of linearly arranged microvessels, a layer that is rich in smooth muscle cells, and fibrous layers. In the article, “Significance of differential characteristics in infantile Kawasaki disease” in volume 49(8), page 755-765, In the process of inputting standard deviation (SD) in Table 1, each 1,000 omitted. Specifically, all members of the writing group are required to complete and submit a Disclosure Questionnaire showing all such relationships that might be perceived as real or potential conflicts of interest. The Kawasaki Disease Clinic at Rady Children’s Hospital-San Diego is dedicated to caring for kids with acute Kawasaki disease. The patient should be monitored for known risk factors of atherosclerosis and his or her family should be counseled accordingly. The disease probably isn’t contagious, but it sometimes happens in clusters in a community. We do not capture any email address. Myocardial abnormalities, including fibrosis and cellular disarrangement, as well as abnormal branching and hypertrophy of myocytes, were detected at all time periods after onset of the disease; their severity was unrelated to the presence of coronary artery abnormalities. For females of childbearing age, reproductive counseling is strongly recommended. Characteristics suggesting disease other than Kawasaki disease include exudative conjunctivitis, exudative pharyngitis, discrete intraoral lesions, bullous or vesicular rash, or generalized adenopathy. The coronary aneurysm presents increasingly abnormal flow conditions, which are unlike other common clinical conditions such as atherosclerosis.183 Within the aneurysm itself, the vessel dilatation results in low blood flow velocities and relative stasis of flow, which predispose the aneurysm to chronic thrombus formation. 5–8 Kawasaki disease is markedly more prevalent in Japan and in children of Japanese ancestry, with an annual incidence of ∼112 cases per 100 000 children <5 years old. For example, false-positive tests are more likely in patients with a previously low probability of coronary disease. Enlargement of the LMCA caused by Kawasaki disease does not involve the orifice and rarely occurs without associated ectasia of the LAD, LCX, or both arteries. The aortic root also should be imaged, measured, and compared with references for body surface area because evidence exists that mild aortic root dilation is common among patients with Kawasaki disease.100 Because pericarditis may be associated with the vasculitis and myocarditis seen in patients with Kawasaki disease, the presence or absence of a pericardial effusion should be noted. No differences between treatment groups in coronary outcomes were noted, with limited statistical power. Kawasaki syndrome: Definition Kawasaki syndrome is a potentially fatal inflammatory disease that affects several organ systems in the body, including the heart, circulatory system, mucous membranes, skin, and immune system. No antiplatelet therapy is needed beyond the initial 6 to 8 weeks after the onset of illness. The inflammation of Kawasaki disease can damage a child’s coronary arteries, which carry blood to their heart. The effects of steroids on coronary artery abnormalities are still uncertain, however. Angiography, intravascular ultrasound (IVUS), transesophageal echocardiography, and other modalities including magnetic resonance angiography (MRA) and ultrafast computed tomography (CT) may be of value in the assessment of selected patients (see below). Kawasaki disease is an illness that causes blood vessels to become inflamed, almost always in young children. Kids are more likely to get it in the winter and spring. Attempts at excision or plication of the coronary artery aneurysm have not been successful and have caused deaths. The ultimate decisions for case management must be made by physicians in light of the particular conditions presented by individual patients. Although aneurysms rarely form before day 10 of illness, perivascular brightness, ectasia, and lack of tapering of the coronary arteries in the acute stage of Kawasaki disease may represent coronary arteritis before the formation of aneurysms. Variations, taking into account individual circumstances, may be appropriate. What are synonyms for Infantile polyarteritis? Having a coronary artery z score ≥2.5 in both the proximal RCA and LAD would be uncommon in the general population. The putative dose-response effect of IVIG forms the theoretical basis for this approach. Treatment with high-dose IVIG is recommended for children with fever of 4 days' duration and 4 of 5 classic clinical criteria, as well as for those with fewer clinical criteria in whom coronary abnormalities are noted by echocardiogram.

Striking immune perturbations occur in acute Kawasaki disease, including marked cytokine cascade stimulation and endothelial cell activation. Our statement on the initial evaluation, treatment in the acute phase, and long-term management of patients with Kawasaki disease is intended to provide practical interim recommendations until evidence-based data are available to define best medical practices. The writing group reviews the available data regarding the initial treatment for children with acute Kawasaki disease, as well for those who have persistent or recrudescent fever despite initial therapy with IVIG, including IVIG retreatment and treatment with corticosteroids, tumor necrosis factor-α antagonists, and abciximab. No prospective data exist to guide clinicians in choosing an optimal regimen, so recommendations are based on known pathophysiology, retrospective case series in children with Kawasaki disease, and extrapolation from experience in adults with coronary disease. Patients with fever for ≥5 days and <4 principal features can be diagnosed as having Kawasaki disease when coronary artery disease is detected by 2-dimensional (2D) echocardiography (2DE) or coronary angiography. Recommendations for initial evaluation, treatment in the acute phase, and long-term management of patients with Kawasaki disease are intended to assist physicians in understanding the range of acceptable approaches for caring for patients with Kawasaki disease. Timely diagnosis requires careful history-taking and thorough physical examination. It is also possible that the inflammatory infiltrate found between the muscle fibers on postmortem examination in early Kawasaki disease may resolve quickly. Severe hemolytic anemia requiring transfusions is rare and may be related to intravenous immunoglobulin (IVIG) infusion.69–72 Elevation of acute phase reactants, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), is nearly universal in Kawasaki disease, usually returning to normal by 6 to 10 weeks after onset of the illness. Aneurysms are classified as saccular if axial and lateral diameters are nearly equal or as fusiform if symmetric dilatation with gradual proximal and distal tapering is seen. The recommendations are evidence based and derived from published data wherever possible. In the last American Heart Association statement,3,98 aneurysms were classified as small (<5-mm internal diameter), medium (5- to 8-mm internal diameter), or giant (>8-mm internal diameter). This report was copublished in the October 26, 2004 issue of Circulation. Efforts to associate Kawasaki disease with exposure to drugs or to such environmental pollutants as toxins, pesticides, chemicals, and heavy metals have failed, although clinical similarities between Kawasaki disease and acrodynia (mercury hypersensitivity) are notable.

Because the degree of elevation of ESR and CRP may show a discrepancy in some patients at the time of presentation, both should be measured.73 Furthermore, elevation of ESR (but not of CRP) can be caused by IVIG therapy per se; therefore, ESR should not be used as the sole determinant of the degree of inflammatory activity in IVIG-treated patients. Dr Jane W. Newburger has received research grants from Philips Medical and Pfizer and is a National Heart, Lung, and Blood Institute Advisory Council member; Dr Masato Takahashi has received a research grant from Sonofi-Synthelabo; and Dr Jane C. Burns has received a research grant from Centocor. The goals of therapy include reestablishing coronary patency, salvaging the myocardium, and improving survival.191 In adult trials, treatment with streptokinase has demonstrated a lower incidence of bleeding than have other agents (eg, Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto [GISSI-1], Second International Study of Infarct Survival [ISIS-2]),192,193 but potential allergic complications limit its use in patients with a history of streptococcal pharyngitis within the past 6 months. Causes Kawasaki disease occurs most often in Japan, where it was first discovered. Catheter intervention is contraindicated for individuals who have vessels with multiple, ostial, or long-segment lesions (evidence level C). With appropriate therapy, the fever usually resolves within 2 days. These are called aneurysms. Bullous and vesicular eruptions have not been described. They could raise a child’s risk of artery blockages, which can cause internal bleeding and heart attacks. Nonspecific symptoms can precede or … The disease is seen more often in boys than in girls. Mechanical restoration of coronary blood flow (ie, the use of immediate coronary angioplasty or stent placement) is effective in adults and has been used in a small number of children (evidence level C).23 The choice of method to reestablish perfusion in children with Kawasaki disease and coronary thrombosis should be based on that which can be administered with the greatest expertise in a timely fashion. Therapeutic regimens used in patients with Kawasaki disease depend on the severity of coronary involvement and include antiplatelet therapy with aspirin, with or without dipyridamole or clopidogrel; anticoagulant therapy with warfarin or low-molecular-weight heparin; or a combination of anticoagulant and antiplatelet therapy, usually warfarin plus aspirin. This regression usually occurs by myointimal proliferation, although more rarely the mechanism of regression can be organization and recanalization of a thrombus.34,223,224 Pathological examination reveals fibrous intimal thickening despite a normal coronary artery lumen diameter. Care must be taken in making the diagnosis of ectasia because of considerable normal variation in coronary artery distribution and dominance. Its positive predictive value was less satisfactory, however; the frequencies of the development of coronary artery abnormalities in boys and girls who were classified as high risk were only 13.8% and 5.5%, respectively. Synonyms for Infantile polyarteritis in Free Thesaurus. All rights reserved. Although its effectiveness in reducing the prevalence of coronary artery aneurysms is unproven, therapy with infliximab or other agents directed at TNF-α might be considered in patients who are resistant to IVIG and steroids (evidence level C). Multiple imaging planes and transducer positions are required for the optimal visualization of all major coronary segments (Table 3, Fig 2). Cardiac auscultation of the infant or child with Kawasaki disease in the acute phase often reveals a hyperdynamic precordium, tachycardia, a gallop rhythm, and an innocent flow murmur in the setting of anemia, fever, and depressed myocardial contractility secondary to myocarditis. Patients with angiographically documented regression of coronary artery aneurysms have shown abnormal thickening of the intima-media complex by IVUS124 and abnormal vasoreactivity in response to various vasodilators.125,126 The long-term clinical implications of these anatomical and functional changes are unknown at this time.
