title: [Neopterine and ige during respiratory-syncytial virus infection in infants].
abstract: The number of studies confirms the correlation between IgE and neopterine levels. One of the forms of revelation of the immune answer of T-cells is the activation of T-cell system, that in its turn results in secretion of IL-2 and INF-gamma by Th-1 subtype cells. Activation of macrophages by INF-gamma the human organism. The target of our research was the evaluation of the role of the marker of macrophage activation -- neopterine in children with recurrent wheezing developed during onset of RSV infection and possible connection with IgE level. In the study 52 children of age from 1 to 12 months having RS-virus infection were included. Two groups were determined as controls -- group of healthy children and children with wheezing of non RSV etiology. Determination of neopterine was performed by enzyme immunoassay method (ELISA). During the RS-virus induced acute respiratory infection the rate of neopterine in the blood serum was significantly decreased in the group of patients with recurrent wheezing in comparison with the I group (first episode of wheezing). At the same time the significant difference between the group with wheezing of non -- RSV etiology and the control group was not observed. Decreasing of neopterin was significant in the II and III groups. IgE levels were elevated significantly in the second group of patients with recurrent wheezing. In this group negative correlation between neopterin and IgE was found.
