Trigger role of infectious agents in the genesis of sudden infant death

Abstract

Purpose. To increase the effectiveness of diagnostic predictors for the development of sudden infant death based on the study of the role of infectious agents.Materials and methods. A retrospective analysis of 120 cases of development of children, suddenly deceased, medical charts of pregnant women, histories of childbirth of mothers was carried out, and the morphological features of the suddenly deceased children were studied. The frequency of distribution and types of viruses detected using enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction test (PCR) in the examined children who died suddenly in their first year of life were analyzed. Statistical analysis of the research results was made in the MedStat software.Results. The frequency of detection of various infectious agents among the deceased from sudden infant death is (64.4 ± 4.2) %. Morphohistological study indicated characteristic signs of catarrhal tracheobronchitis (83.0 ± 5.5) %, focal intraepithelial inflammation of the larynx and trachea (48.9 ± 7.3) %, desquamative catarrhal pneumonia (31.9 ± 6.8) %, as well as acute focal bronchitis (27.7 ± 6.5) %.Conclusion. The performed study confirms that in the genesis of sudden infant death, along with a role of social and economic, medical and biological factors, there is an obvious negative effect of infectious agents, with the infectious activator working as the trigger and provoking sudden infant death.
