چکیده

BACKGROUND Kawasaki Disease (KD) is the most common cause of acquired heart disease in children in developed nations. The KD etiologic agent is unknown but likely to be a ubiquitous microbe that usually causes asymptomatic childhood infection, resulting in KD only in genetically susceptible individuals. KD synthetic antibodies made from prevalent IgA gene sequences in KD arterial tissue detect intracytoplasmic inclusion bodies (ICI) resembling viral ICI in acute KD but not control infant ciliated bronchial epithelium. The prevalence of ICI in late-stage KD fatalities and in older individuals with non-KD illness should be low, unless persistent infection is common. METHODS AND PRINCIPAL FINDINGS Lung tissue from late-stage KD fatalities and non-infant controls was examined by light microscopy for the presence of ICI. Nucleic acid stains and transmission electron microscopy (TEM) were performed on tissues that were strongly positive for ICI. ICI were present in ciliated bronchial epithelium in 6/7 (86%) late-stage KD fatalities and 7/27 (26%) controls ages 9-84 years (p = 0.01). Nucleic acid stains revealed RNA but not DNA within the ICI. ICI were also identified in lung macrophages in some KD cases. TEM of bronchial epithelium and macrophages from KD cases revealed finely granular homogeneous ICI. SIGNIFICANCE These findings are consistent with a previously unidentified, ubiquitous RNA virus that forms ICI and can result in persistent infection in bronchial epithelium and macrophages as the etiologic agent of KD.

Cloning the arterial IgA antibody response during acute Kawasaki disease.

Kawasaki disease (KD) is the most common acquired cardiac disease in children in developed nations. The etiology of KD is unknown but likely to be a ubiquitous microbial agent. Previously, we showed that oligoclonal IgA plasma cells infiltrate coronary arteries and other inflamed tissues in acute KD. We demonstrated that a synthetic Ab made using an alpha H chain sequence prevalent in acute KD ...

Electron Microscopy of Early Cytoplasmic Changes Due to Influenza Virus

Recently improved methods for visualization of thin tissue sections by electron microscopy have been applied to the study of early changes in the bronchial epithelium of mice infected by inhalation of aerosols of influenza virus. In confirmation of previous findings by the authors, inclusion bodies have been demonstrated in ciliated and non-ciliated cells of infected bronchial epithelium. In ad...

Node-First Kawasaki Disease Presented with Marked Pancarditis: a Case Report

Kawasaki disease is an acute inflammatory disorder of medium-sized arteries that predominantly affects cardiac coronary arteries and children under the age of 5 years. Cardiac involvement usually happens later than 10 days after the onset of illness. Most of cardiac complications are coronary artery abnormalities (ectasia or aneurysms) and subclinical myocarditis. Clinical myocarditis (symptoma...

Comparison of early and late intravenous gamma globulin treatment of Kawasaki disease on fever and cardiovascular complications

Background: Cardiac involvement was the major leading cause of death in patients with Kawasaki and IVIG administration reduces cardiac complications. The objective of this study was to determine the frequency of cardiovascular complications and duration of fever with regard to the time of intravenous immunoglobulin (IVIG) administration of patients with Kawasaki disease. Methods: This follow...

Viral inclusion bodies in tracheobronchial epithelium of asymptomatic subjects.

During a survey conducted for the cytodiagnosis of early bronchogenic carcinoma, cytoplasmic viral inclusion bodies were found sporadically in tracheobronchial smears of asymtomatic patients of both sexes (ages ranging from 18 to 80 years) undergoing general endotracheal anesthesia for surgery. A review of 3,049 cases performed to assess the frequency of occurrence of this phenomenon showed a 1...
