[INF-gamma during respiratory-syncytial induced obstructive respiratory syndrome in infection in children under one year of age].
Lately the connection of Asthma and RSV drew the sufficient attention. The recurrent wheezing developed during the RSV in children is particularly frequent in the families having history of atopy. The decreased expression of INFgamma may play the role in the pathogenesis of RSV infection. The target of our research was the study of the rate of INFgamma during various clinical courses of RSV-infection and definition of its role in the pathogenesis of ARVI. 52 children with RSV-associated wheezing have been studied, who had first (32) or recurrent episode (20) of bronchial obstruction and whose families had occurrence of atopy. 52 children with non RSV-associated wheezing (III group) and 10 healthy children up to 12 months of age (IV group) were considered as the control groups. Children from all four groups were from families with the history of atopy. INFgamma was measured by enzyme immunoassay (ELISA). Comparison of two groups of wheezing children with RSV infection showed significant reduction of INFgamma level in the group of children with recurrent wheezing vs. the group with first episode of wheezing. INFgamma levels were significantly higher in the two control groups. During the acute respiratory infection induced by RS-virus, which proceeds with the obstruction of respiratory tract (wheezing), reduction of INFgamma was noted and higher frequency of wheezing episodes is associated with more prominent alteration.
