Background—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.

Diagnosis, Treatment, and Long-Term Management of Kawasaki Disease A Statement for Health Professionals From the Committee on Rheumatic Fever, Endocarditis and Kawasaki Disease, Council on Cardiovascular Disease in the Young, American Heart Association

Background. 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. Coronary artery aneurysms or ectasia develop in ∼15% to 25% of untreated children and may lead to ischemic heart disease or sudden death.
 Methods and Results. A multidisciplinary committee of experts was convened to revise the American Heart Association recommendations for diagnosis, treatment, and long-term management of Kawasaki disease. The writing group proposes a new algorithm to aid clinicians in deciding which children with fever for ≥5 days and ≤4 classic criteria should undergo electrocardiography, receive intravenous gamma globulin (IVIG) treatment, or both for Kawasaki disease. 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. Long-term management of patients with Kawasaki disease is tailored to the degree of coronary involvement; recommendations regarding antiplatelet and anticoagulant therapy, physical activity, follow-up assessment, and the appropriate diagnostic procedures to evaluate cardiac disease are classified according to risk strata.
 Conclusions. Recommendations for the 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. The ultimate decisions for case management must be made by physicians in light of the particular conditions presented by individual patients.

Preterm (PT) infants are at increased risk of experiencing complications of vaccine-preventable diseases but are less likely to receive immunizations on time. Medically stable PT and low birth weight (LBW) infants should receive full doses of diphtheria, tetanus, acellular pertussis, Haemophilus influenzae type b, hepatitis B, poliovirus, and pneumococcal conjugate vaccines at a chronologic age consistent with the schedule recommended for full-term infants. Infants with birth weight less than 2000 g may require modification of the timing of hepatitis B immunoprophylaxis depending on maternal hepatitis B surface antigen status. All PT and LBW infants benefit from receiving influenza vaccine beginning at 6 months of age before the beginning of and during the influenza season. All vaccines routinely recommended during infancy are safe for use in PT and LBW infants. The occurrence of mild vaccine-attributable adverse events are similar in both full-term and PT vaccine recipients. Although the immunogenicity of some childhood vaccines may be decreased in the smallest PT infants, antibody concentrations achieved usually are protective.

Sequential Follow-Up Results of Catheter Intervention for Coronary Artery Lesions After Kawasaki Disease Quantitative Coronary Artery Angiography and Intravascular Ultrasound Imaging Study

Kawasaki disease (KD) is an acute inflammatory vasculitis of childhood which was initially described more than 4 decades ago, yet the specific etiology remains unknown. It has become the most common cause of acquired cardiovascular disease in children in the United States. Advances in clinical therapies have reduced, but not eliminated, the incidence of coronary artery abnormalities in affected children. Pathophysiology seems to include an intense elaboration of cytokines, endothelin, and other vasoactive mediators resulting in the development of vascular endothelial changes that may leave a permanent impact on vascular integrity. Treatment with intravenous immune globulin and aspirin remains the primary management strategy and steroid therapy remains contoversial. In severe circumstances, coronary reperfusion strategies are required, and coronary artery surgery in children with KD has been required, albeit infrequently. KD may be a harbinger for early onset coronary artery disease in adults. Recently developed AHA recommendations have amended diagnostic strategies and indicated a stratified approach to the long-term follow up of this enigmatic yet widespread disease.

Kawasaki disease: diagnosis, management, and long-term implications.

Background Percutaneous transluminal coronary angioplasty (PTCA) has rarely been performed on patients with coronary lesions that result from Kawasaki disease. In this study, we retrospectively evaluated the effectiveness of PTCA in five patients with coronary arterial stenosis that resulted from Kawasaki disease and reviewed previous reports for possible indicators of PTCA effectiveness. Methods and Results Five patients, ranging in age from 2 to 16 years (median, 8 years), underwent conventional PTCA for localized stenosis. The lesion targeted for PTCA was located in the middle right coronary artery of three patients and in the left anterior descending artery in two patients. In four of the five patients, PTCA was angiographically effective, with stenosis rates improving from 84±10% to 33±11% (P<.05). When the previously reported cases of six similar patients were taken into consideration, the only predictor of successful PTCA seemed to be the time elapsed between the onset of Kawasaki disease and perfo...
