| Sumario: | Specific perinatal infections make about 30% in causal structure of infant mortality. Among the respiratory diseases of perinatal period, pneumonias take a special place, due to higher frequency, severity, complications and adverse outcomes. The aim of this work was to study microflora and factors of innate immunity (TLR2, TLR4, HBD-1, HBD-2, TNFα and NF-kB) at the level of the mucous membranes of the upper respiratory tract during intrauterine infection of fetus and perinatal pneumonia. Causal structure of ventilator-associated pneumonias at the intensive care unit represents a broad spectrum of pathogens with high resistance to antibiotics. Changes of immunological parameters (recognizing structures, i.e., TLR2, TLR4, HBD-1; HBD-2 defensins; proinflammatory TNFα cytokine and NF-kB transcription factor) in patients with intrauterine infections and pneumonia are ambiguous. Decreased expression of TLR2, TLR4 genes, along with increased of TNFα and NF-kB gene expression. These changes correlate with type of infectious pathogen, thus allowing us to assume that the pathogen, due to pathogenicity factors, may directly affect innate immunity mechanisms. |
