Respiratory viruses associated with acute wheezing in hospitalized young
children in Jordan
Abstract
Background Viral acute respiratory infections (ARI), including
respiratory syncytial virus (RSV) and human rhinovirus (HRV), induce
acute wheezing episodes in young children. This study aimed to determine
the association of wheezing with respiratory viruses, demographic and
clinical characteristics in young children. Methods A prospective viral
surveillance study in children less than two years, admitted with fever
and/or respiratory symptoms in Amman, Jordan, 2010-2013. Demographic and
clinical characteristics were collected through parent interviews and
medical chart abstraction. Nasal/throat swabs were collected and tested
by qRT-PCR. Multivariable logistic regression was fit to assess the
association between wheezing and a-priori selected predictors of
interest. Results Of 3168 children enrolled, 1757 (55%) were
wheezing-positive, who were older, more likely to have a respiratory
virus, underlying medical conditions, personal history of reactive
airway disease (RAD), and a family history of asthma, compared to
wheezing-negative children. Older age, personal history of RAD, family
history of asthma, RSV and HMPV were associated with higher odds of
wheezing in an adjusted regression model. Conclusion In young children,
RSV and HMPV were associated with higher odds of wheezing. Longitudinal
studies are needed to evaluate the association between early childhood
viral ARI and recurrent wheezing later in childhood, to guide preventive
interventions.
