Scientists estimated the role of three indicators of blood test indicators affecting the survival rate of patients with a severe form of COVID-19. It is reported by RIA Novosti with reference to Journal of Internal Medicine.
Researchers from Spain and Canada have tried to identify key to determine the degree of fatal outcome the factor and drew attention to the level of specific antibodies, the total number of antigens and the amount of virus RNA in the blood.
It turned out that it was the low level of specific antibodies against the spike protein (S-protein) of the coronavirus that appear after vaccination correlates with a high risk of death. The remaining two parameters are associated with the first: in the absence of antibodies of N-antigemia, about two and a half times higher than at high levels, and the viral RNA load is inversely proportional to the number of antibodies. In other words, those who had a bad antibody response had high levels of viral RNA and scattered virus proteins in the blood.
October 5, Canadian researchers have shown that concern new SARS-COV-2 versions have greater virulence than the original “Wuhan”. Specialists from the University of Toronto appreciated more than 212 cases of coronavirus infection, recorded from February to June 2021 in the province of Ontario. 76 percent of the illness infected “alpha”, “beta” and “gamma” -rentions associated with the N501Y mutation in the coronavirus S-protein, which increases its transmission. 2.8 percent infected “Delta” -varis. It was found that such people were, as a rule, younger and more often have concomitant diseases compared to those who have become infected with other options. When “Alfa”, “Beta” and “Gamma” -variants, the risk of hospitalization of patients was higher by 52 percent. The risk of getting into the resuscitation department is 89 percent, die – by 51. For the “delta” -variant, these indicators were 108, 235 and 133 percent, respectively.
