| Summary: | The COVID-19 pandemic which began in March 2020 has again drawn attention to the problem of treating primary viral pneumonia (PVP), wherein damage to the tissues of the lower respiratory tract including functionally important alveolocytes occurs as a result of cell infection by pathogens of the Virae Kingdom. Whereas treatment of bacterial pneumonia is based on the basic approach related to the use of antibiotics (which effectiveness needs to be verified more often than ever due to the “curse of the resistance effect” — that, however, does not cancel the essence of the basic approach), efficient PVP treatment is feasible only in case of available etiotropic, but catastrophically few, drugs. Such drugs in case of the influenza A virus (Articulavirales: Orthomyxoviridae, Alphainfluenzavirus) have been known since the second part of the XXth century. However, no consensus was achieved among clinicians regarding particularly dangerous human coronaviruses (Nidovirales: Coronaviridae, Betacoronavirus) which threat has driven the world epidemiology in the XXIst century: SARS-CoV (subgenus Sarbecovirus), MERS-CoV (Merbecovirus), SARS-CoV-2 (Sarbecovirus). And we should be prepared to the fact that increase in population density and scaling up of anthropogenic impact on ecosystems elevates a probability of overcoming interspecies barriers by natural focal viruses and their penetration into the human population with adverse epidemic consequences. Therefore, PVP therapy should be developed systematically in the nearest future. Antimicrobial peptides (AMP) as the components of non-specific innate immunity against a wide range of infectious pathogens: bacteria (Bacteria), microscopic fungi (Fungi) and viruses (Virae) may serve as a platform for developing such system. Our review justifies a way to select such platform and provides well-known examples of successfully used AMP in treatment of PVP and related pathological conditions. |
