Abstract


The objective of our study was to identify new respiratory viruses in infants with bronchoobstructive syndrome (obstructive bronchitis and exacerbation of bronchial asthma). We examined 28 children aged from 5 months to 6 years. The average age of the patients was 33.7 months (95% CI 24.5–43.0). Viruses have been identified in 75 % of patients. In 39.3 % we found bocavirus. Metapneumovirus was detected in 10.7 % of patients. Exacerbation of bronchial asthma 2.3 times more likely was associated with bocavirus infection compared to patients with obstructive bronchitis (RR = 2.3 (95% CI 0.9–6.2)). Duration of bronchoobstructive syndrome in children with bronchial asthma was significantly higher (p < 0.0001) than in children with obstructive bronchitis — 5.3 days (95% CI 4.1–6.4) versus 2.7 days (95% CI 2.3–3.1). The findings confirm a significant role of viral infection and new respiratory viruses in causing bronchoobstructive syndrome in children.
