Abstract
Acute asthma exacerbations (AAE) are episodes characterized by potentially life-threatening and rapidly deteriorating asthma symptoms. Viral respiratory infections are one of the major triggers in the pathophysiology of childhood asthma exacerbations. In this study, we aimed to determine the distribution of viral agents among pediatric AAE patients.
One hundred and three AAE patients, aged 5 or older, hospitalized between from February 2017 through February 2020 at Pediatric Immunology and Allergic Diseases Unit were included in this study. Fifty patients (48.5%) were female, and the mean age of the patients was 108.2 months. Viruses were detected in 58 (%56.3) of the patients, in 5 of whom more than one virus type was detected. The most commonly detected virus was human rhinovirus (n=43, 67.1%).
Other types included respiratory syncytial virus (n=8; 12.5%), influenza (n=6; 9.3%), human metapneumovirus (n=4; 6.2%), adenovirus (n=1; 1.5%), enterovirus (n=1; 1.5%), and parainfluenza (n=1; 1.5%). Viral agents were detected in 29 out of the 47 patients with allergic asthma, with human rhinoviruses comprising the majority (18 patients). The mean length of hospital stay was 7.89 days.
Human rhinovirus is the most common virus that triggers AAE, with similar distributions in allergic and non-allergic asthma. We found no correlation between virus type and the length of hospital stay.
