Novel Human Rhinoviruses and Exacerbation of Asthma in Children1
نویسندگان
چکیده
To determine links between human rhinoviruses (HRV) and asthma, we used data from a case-control study, March 2003-February 2004, among children with asthma. Molecular characterization identified several likely new HRVs and showed that association with asthma exacerbations was largely driven by HRV-A and a phylogenetically distinct clade of 8 strains, genogroup C.

Spirometry Findings Following Treatment with Oral and Inhalant Corticosteroids in Mild to Moderate Asthma Exacerbation in Children
Introduction: Asthma exacerbation is common in children. Treatment with oral corticosteroids (OCS) and inhaled corticosteroids are suggested for asthma exacerbation. It is shown that inhaled corticosteroids has similar outcome in reducing asthma symptoms compared to OCS. But few studies have evaluated the pulmonary function changes in these two treatments. In this study, we evaluated the chang...
متن کاملIL-33-dependent type 2 inflammation during rhinovirus-induced asthma exacerbations in vivo.
RATIONALE Rhinoviruses are the major cause of asthma exacerbations; however, its underlying mechanisms are poorly understood. We hypothesized that the epithelial cell-derived cytokine IL-33 plays a central role in exacerbation pathogenesis through augmentation of type 2 inflammation. OBJECTIVES To assess whether rhinovirus induces a type 2 inflammatory response in asthma in vivo and to define...
متن کاملComparing Serum Procalcitonin Levels Between Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease and Patients with Acute Exacerbation of Asthma
Background and purpose: Serum procalcitonin (PCT) indicates a bacterial infection that can reduce the administration of antibiotics. The aim of this study was to compare serum procalcitonin levels in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) and asthma and its relationship with lung function and inflammatory factors. Materials and methods: In this cross-s...
متن کاملExpression of the Apoptosis Inhibitor Bcl-2 in Sputum Eosinophils in Patients with Asthma
Background and Objectives: Apoptosis of eosinophils is of significant value in assessing the airway inflammation in patients with asthma. Our purpose was to investigate the degree of expression of the Bcl-2 protein in sputum eosinophils during acute asthma exacerbation and its relationship with exacerbation severity. Materials and Methods: The study was carried out in Mostafa Khomeini Ho...
متن کاملPathogenesis and management of virus infection-induced exacerbation of senile bronchial asthma and chronic pulmonary emphysema.
The number of senile patients with therapy resistant bronchial asthma, chronic pulmonary emphysema increases due to the habit of smoking and increased number of older people, and these inflammatory pulmonary diseases are the leading causes of death worldwide. Rhinoviruses cause the majority of common colds, and provoke exacerbations of bronchial asthma and chronic pulmonary emphysema. Here, I r...
