Pathogenesis of formation of frequent respiratory infections in children with Epstein-Barr virus and cytomegalovirus infection
The goal was to clarify the pathogenesis of the formation of frequent respiratory infections in children with Epstein-Barr virus and cytomegalovirus infection on the basis of studying the microbial landscape of anti-infective and mucous membranes of the oropharynx resistance. The results of clinical and laboratory examination of 47 frequently and chronically ill children aged 6 months to 7 years with active Epstein-Barr virus and / or cytomegalovirus infection are presented. 19 children (40,4%) had mono-CMV infection, 6 patients (12,8%) - Mono-Epstein-Barr virus infection, 22 children (46,8%) - mixed herpesvirus infections. The carrier state of <i>S. рneumoniae</i> was revealed in 70,0% of cases, the carrier state of <i>S. aureus</i> - in 40,5% of cases against the background of decrease normal mouth microflora. Deficiency of nonspecific secretory immunoglobulin class A was established in 98% of cases, destructive changes of epiteliotsits on a mucous membrane of an oral cavity children was established in 93,9 % of cases. The presence of eosinophils in the mucosa of the oropharynx was reported in 29,8% of patients, in 78,7% of patients - the presence of polymorphonuclear leukocytes of more than 5 cells in a field of view. A scheme of the pathogenesis of recurrent respiratory diseases in often long-term ill children is desined.
