The coronavirus and the fight against it. The situation at home and in the world.
Antibody-rich blood plasma from convalescent patients is not effective in treating Covid-19, according to an Indian study reported Friday. According to a study published in the British Medical Journal, convalescent blood plasma did not reduce mortality and prevent the disease from worsening.
However, Donald Trump called plasma treatment a historic breakthrough in August, and Cecília Müller even last week referred to it as an “extremely effective treatment” to help moderate patients avoid the intensive care unit. But a case study involving about 400 Covid-19 patients does not appear to support this. The emergency use of the treatment has also been approved by the United States and India.
„The experiment showed that blood plasma had little effect on patients shedding the virus, but it was not enough to recover from the disease. said Simon Clarke, a microbiologist at the University of Reading. “Bottom line: it has no healing effect.Clarke added.
The study was conducted in 464 moderately severe Covid-19 patients who were divided into two groups. One group received blood plasma and standard medical care, while the control group received no plasma, only conventional care. After seven days, some of the symptoms in the plasma-treated patients were alleviated and the antibodies destroyed the virus to a greater extent in their bodies, but 28 days later, there was no difference between the death rate and the exacerbation of the disease in the two groups.
„The role of blood plasma is disappointing, but not entirely surprising. “ said Ian Jones, a virologist at the University of Reading, who said that plasma treatment could be effective if someone received it very soon after infection and therefore suggested that plasma treatment experiments be performed on people at those who have recently been diagnosed with the infection. However, he stressed that it is still safer for people to protect themselves against infection and not contract the virus. (Reuters / MTI)
