ABSTRACT
PURPOSE:
Bronchial asthma was reported to be an important risk factor of severe respiratory symptoms due to pandemic H1N1 influenza infection. In this study, we investigated if there was any difference in the clinical features of children with H1N1 pneumonia according to their atopic or asthma status.METHODS:
Eighty-eight children admitted with pneumonia due to reverse transcriptase-polymerase chain reaction-confirmed H1N1 influenza infection during the period from September 2009 to January 2010 were enrolled. These patients were divided into atopic (n=42) and non-atopic (n=46) groups. The atopic group consisted of 23 asthmatic children and 19 non-asthmatic children with allergic rhinitis or atopic dermatitis. We retrospectively analyzed the medical records of the patients to investigate if there was any difference in the clinical features according to their atopic or asthma status.RESULTS:
There was no age difference between atopic and non-atopic patients. Male preponderance was observed only in the atopic group.(P<0.05) The occurrence of wheezing, severity of respiratory symptoms, and number of emergency-room visits were significantly higher in atopic than non-atopic patients.(P<0.05) However, those variables showed no difference between asthmatic and non-asthmatic patients within the atopic group. Twelve patients in the atopic, non-asthmatic group were followed for 1 year after discharge, and 5 patients were diagnosed to have asthma with recurrence of wheezing and/or positive results to methacholine challenge tests.CONCLUSION:
Our study shows that H1N1 influenza infection may cause more severe respiratory symptoms in atopic patients than in non-atopic patients, regardless of their asthma status. allergic rhinitis.(R=0.195, P=0.002). About 17% of the parents who care the allergic rhinitis children experienced the work absence due to their child's illness.
