Abstract


Relevance. In recent years, there has been a steady increase in the incidence of children morbidity, in the structure of which infectious pathology occupies a leading position. The development of «minimal persistent inflammation» of the upper respiratory tract mucosa is the basis for the persistence of microflora, the entrance gate for allergens and irritants, and creates conditions for the timing of the inflammation. The aim of the study: based on the study of the features of the immune system and interferon system in immunocompromised children of early age suffering from co-infections: return ARVI associated with atypical chronic herpes virus infections, to develop a new program of local and systemic interferon therapy and evaluate its effectiveness. Materials and methods: We observed 30 children aged 1-4 years, 16 boys and 14 girls suffering from recurrent ARVI associated with various atypical chronic active herpes virus infections (ACHA-HVI) (HSV I/II, EBV, CMV, HHV VI). The comparison group was 20 conditionally healthy children, comparable by sex and age. We used clinical and immunological methods: ELISA, PCR, cytofluorimetry. Results: A clinical and anamnestic investigation showed that young children had clinical features of immunocomprometization: a high rate of recurrent ARVI of 10-15 or more episodes per year, and the duration of these episodes ranged from 7 to 12 days, while in 100 % of cases there were recurrent monoand/or mixed ACHA-HVI. A study of the state of the immune system and the interferon system showed that children of the study group were deficient in T cytotoxic lymphocytes, natural killer cells, serum IFNα, serum IgA, and various disorders of neutrophil granulocytes (NG). A new immunopathogenetically based program of local and systemic therapy with recombinant IFNα2b in combination with antioxidants has been developed. This program demonstrated a high clinical-immunological effectiveness, providing in a significant reduction of ARVI episode rates, a reduction in the duration of IRVI, as well as the number of complicated ARVI, a decrease in the replicative activity of herpes viruses in a field of restoration of the interferon system, a significant improvement of antiviral and antibacterial immune response. Conclusions: A new immunopathogenetically based program of systemic and local IFNtherapy for immunocompromised young children has been created. The high clinical-immunological effectiveness and immunoprophylactic orientation of the developed local and systemic program of interferonotherapy have been demonstrated.
