The pilot studies involved two small sets of critically ill coronavirus patients in different hospitals, the Guardian reported.
In a study, doctors in Wuhan – the epicenter of the first epidemic of the current pandemic – administered blood plasma infusions taken from recovered patients to 10 seriously ill coronavirus patients.
In three days, the symptoms of hospital patients improved as the level of virus in their system decreased, possibly due to the antibodies they received from the plasma of the survivors, the researchers said in their report, published Monday by the US National Academy of Sciences. None died, the scientists added.
Another study by doctors in Shenzhen performed the same plasma infusion on five critically ill coronavirus patients – and all have improved, three of whom were weaned from their respirators within 10 days, said the Guardian , citing a report from the US Journal of the American Medical. Association.
Still, the results of a larger patient base are needed, the researchers said.
British Pharmacological Society president Munir Pirmohamed told The Guardian that at least all of Wuhan’s patients received other treatments, including antiviral drugs, during the study.
“It is also important to remember that there are potential safety concerns with convalescent plasma, including the transmission of other agents and the improvement of antibodies to the disease,” he said. “Even if it is proven to work, scalability to treat large numbers of patients can become an issue. “
Blood plasma is the part of the blood that includes elements such as proteins, sugars, fats, including cholesterol and amino acids and vitamins, according to the Merriam-Webster dictionary.
