Interferon production in children with respiratory syncytial, influenza, and parainfluenza virus infections.

Abstract

To better understand the recovery process of infants with lower respiratory tract disease due to respiratory syncytial virus, the production of interferon by 129 children (ages 10 days to 24 months) with RSV infection was compared to that of 20 children with influenza (ages 1 to 36 months), and 37 children with parainfluenza virus infection (ages 4 to 66 months). Interferon assays of 285 nasal washes from children with RSV revealed that interferon production occurred in only 5 (4%) of the children. Significantly more children infected with infleunza virus, 55% (P less than 0.001), and parainfluenza virus, 30% (P less than 0.001), produced interferon. In addition, the quantity of interferon produced by children with RSV (geometric mean titer = 2) was significantly less than that of children with influenza (GMT = 26.8, P less than 0.001) and parainfluenza virus (GMT = 23.5, P less than 0.001). In the children infected with RSV, in constrast to those with influenza, interferon detection was not associated with diminished shedding of virus.
