"In 80 people, an infusion of plasma decreased the risk of developing a severe case of Covid by 48 percent, compared with another group of 80 who received a saline solution instead, the study found. But the study’s parameters were strict: Everyone enrolled in the trial was at least 65 years old — a group known to be at higher risk of falling seriously ill. About half of the participants also had health conditions that made them more vulnerable to the virus. And the plasma therapy, which was screened to ensure it contained high levels of antibodies, was always given within three days of when the patients started to feel symptoms.
“We went as early as we could,” Dr. Polack said. Administering the therapy too late in the course of disease, he said, is akin to allowing a burglar to ransack a home for hours before deciding to call the police. An early dose, on the other hand, has the potential to nip a blooming infection in the bud.
In countries like Argentina, plasma might be one of the best treatment options available, Dr. Polack said. Plasma infusions in Buenos Aires, he said, cost less than $200 a patient. “It’s more accessible, more inexpensive, more universal,” he said."
Respiratory failure is expected in Lithuania. It's a mistake. Plasma should be used much earlier in those groups of patients whose chances of surviving the disease are low.
