Antibody-rich blood plasma from recovering patients is not effective in treating Covid-19, according to a study conducted in India that was reported on Friday.
According to a study published in the British Medical Journal
Convalescent blood plasma does not reduce mortality.
it also did not prevent the disease from worsening, the MTI reported.
US President Donald Trump called plasma treatment a landmark breakthrough in August, but a case study involving more than four hundred 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 has little effect on patients shedding the virus, but that is not enough to recover from the disease. Bottom line: it has no healing effect.
Said Simon Clarke, a microbiologist at the University of Reading.
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 relieved 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
Ian Jones, a virologist at the University of Reading, said
Plasma treatment can be effective if someone receives it shortly after infection.
therefore, it recommended that plasma treatment experiments be performed on people who have recently been diagnosed with the infection. However, he stressed that
It is still safer for people to defend themselves against the infection and not to contract the virus.
