Interleukin‐6, interleukin‐8, interleukin‐11, and interferon‐γ levels in nasopharyngeal aspirates from wheezing children with respiratory syncytial virus or influenza A virus infection

Interleukin‐6, interleukin‐8, interleukin‐11, and interferon‐γ levels in nasopharyngeal aspirates... The differences between respiratory syncytial virus (RSV) and influenza A virus (IFAV) in the pathogenesis of wheezing in young children have not been clearly defined. The aim of this study was to assess the contributions of RSV vs IFAV in the pathogenesis of upper airway inflammation in wheezy young children. We compared interleukin (IL)‐6, IL‐8, IL‐11, and interferon‐γ (IFN‐γ) levels in nasopharyngeal aspirates (NPA) from non‐asthmatic children with respiratory virus infections (RSV in 17 children and IFAV in 13 children), asthmatic children with viral infections (RSV in nine children, IFAV in 10 children), and 22 unaffected healthy children (controls). Levels of IL‐11 in NPA from asthmatic children were significantly higher than those from non‐asthmatic children with RSV infection, and RSV infection enhanced the IL‐11 production in NPA significantly compared to IFAV infection. Nasopharyngeal epithelium from children with RSV infection secreted more IL‐6 than that of children with IFAV infection. There was little difference in the IL‐8 and IFN‐γ levels between asthmatic and non‐asthmatic children with RSV or IFAV infection. In conclusion, asthma enhanced IL‐11 production in RSV infection rather than IFAV infection in early childhood. There was a trend towards greater IL‐6 production in RSV infection compared with IFAV infection. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Pediatric Allergy and Immunology Wiley

Abstract

The differences between respiratory syncytial virus (RSV) and influenza A virus (IFAV) in the pathogenesis of wheezing in young children have not been clearly defined. The aim of this study was to assess the contributions of RSV vs IFAV in the pathogenesis of upper airway inflammation in wheezy young children. We compared interleukin (IL)‐6, IL‐8, IL‐11, and interferon‐γ (IFN‐γ) levels in nasopharyngeal aspirates (NPA) from non‐asthmatic children with respiratory virus infections (RSV in 17 children and IFAV in 13 children), asthmatic children with viral infections (RSV in nine children, IFAV in 10 children), and 22 unaffected healthy children (controls). Levels of IL‐11 in NPA from asthmatic children were significantly higher than those from non‐asthmatic children with RSV infection, and RSV infection enhanced the IL‐11 production in NPA significantly compared to IFAV infection. Nasopharyngeal epithelium from children with RSV infection secreted more IL‐6 than that of children with IFAV infection. There was little difference in the IL‐8 and IFN‐γ levels between asthmatic and non‐asthmatic children with RSV or IFAV infection. In conclusion, asthma enhanced IL‐11 production in RSV infection rather than IFAV infection in early childhood. There was a trend towards greater IL‐6 production in RSV infection compared with IFAV infection.
