ABSTRACT
To date, in the context of the COVID 19 pandemic, there are rumors and speculations about the consequences of the infection, as well as a concern on growing cancer risk due to vaccines and vaccination. In this study we reviewed the concepts of the viral action on cancer development and analyzed the data on the possibility of the malignant effect of the SARS-CoV-2 virus on cells. Analysis of the literature data showed that SARS-CoV-2 damages cells, like other viruses, but does not lead to their mutations. There are no changes in DNA, there is only misregulation of repression and expression of the genome, a perversion of signaling intercellular interactions that disrupt the mechanisms of differentiation and specialization of cells. The need of viruses to multiply in cambial cells of tissues contributes to the induction of their proliferation and the lack of specialization. Thus, the available information on the cytopathic effects caused by viruses in cells infected with COVID-19 does not yet provide information on the malignant effect of SARS-CoV-2. Our study is aimed at collecting and analyzing data that are necessary for planning effective treatment of patients with COVID 19 and predicting outcomes in the long term after the disease.
ABSTRACT
One of the formidable complications of SARS-COV-2 infection leading to death is coagulopathy. The mechanisms of the development of this pathology at the present stage have not been studied, and clinical blood tests indicate that against the background of normal blood clotting indices, only the Ddi-D-dimer protein exceeds the norm many times over. The aim of the study was to study and analyze biochemical parameters in patients of Primorsky Region (Russia) infected with SARS-COV-2 against the background of concomitant vascular pathology and the development of DIC syndrome. The authors came to the conclusion about the existence of two mechanisms of circulatory disorders in the vessels of the microvasculature, associated with the violation of the integrity of the vascular wall and destruction of erythrocytes. Further research is needed to study the mechanisms of SARS-CoV-2 aggression, leading to thrombotic complications.
