Abstract

The aim of the study was to investigate the clinical course of acute Epstein-Barr virus infection in children with the syndrome undifferentiated connective tissue dysplasia. We examined 127 patients aged 6 months to 15 years acute Epstein-Barr virus infection. The study was an open-controlled, parallel-group. Syndrome undifferentiated connective tissue dysplasia verified in 69% of children: mild dysplasia of the connective tissue is installed in 46 patients (36.2%), moderate – in 41 children (32.3%), severe degree is not diagnosed. A total of 40 (31.5%) of children surveyed had no phenotypic features of connective tissue dysplasia. The peculiarities of the clinical course of acute Epstein-Barr virus infection in patients with undifferentiated connective tissue dysplasia include an increase severity of infection by increasing the duration of fever, severity and persistence polylimphoadenopathii, frequent development of parenchymal Epstein-Barr virus associated hepatitis. Active proliferation of virus-infected Epstein-Barr virus lymphocytes occurs in all organs, with lymphoid tissue and is accompanied by infiltration and histologic changes in lymph nodes, liver, spleen, etc. In combination with the weakness of connective tissue structures that causes the symptoms of acute polymorphic Epstein-Barr virus infection and nature of the complications. We examined patients revealed changes in the indicators of collagen metabolism, indicating their partial degradation. The severity of these changes varies depending on the severity of the syndrome of connective tissue dysplasia and paired with the severity of virus-infected Epstein-Barr. When verification of the second degree of connective tissue dysplasia in patients with acute Epstein-Barr virus infection with high probability we can predict the development of severe infection that occurs in liver in the form of the Epstein-Barr virus
associated hepatitis.
