What is plasma therapy
scientists and researchers exploring various avenues to come up with medical treatments that can fight the novel coronavirus. one such treatment that’s in focus right now is convalescent plasma therapy. here, we explain what the convalescent plasma therapy is, benefits and risk involved, what past research says, and more.
The deadly novel coronavirus has infected over 2 million people around the world. and yet there is no treatment available to cure the deadly disease. scientists and doctors are exploring drugs, vaccines, and multiple other treatments to fight COVID-19.
one such treatment in plasma therapy. A 49-year-old-man, the first coronavirus patient who was administered plasma therapy in the Max hospital, Saket, has shown positive results. the patient is now off the ventilator support, the hospital said on Monday.
Indian council of medical research (ICMR) has recently allowed states to start clinical trials of plasma therapy. nearly 100 institutes have shown interest to study how safe and efficient plasma therapy is in treating COVID-19 several states like Kerala, Gujrat, and Punjab have already started to use plasma therapy for COVID-19 patients.
How it’s works of plasma therapy the idea behind this therapy is that immunity can be transferred from a healthy person a stick patient using convalescent plasma. this therapy uses antibodies, from the blood of a recovered coronavirus patient to treat to another critical patient. the recovered COVID-19 patient’s blood develops antibodies to battle against to COVID-19. once the blood of the second patient, those antibodies will starting fighting against coronavirus in the second person.
In this technique, the blood is ejected from the recovered patient from COVID-19. Then the serum is separated and screened for the virus-neutralizing antibodies rich serum is then administered to a COVID-19 patient showing severe symptoms.
According to Houston Methodologist, the process takes around one hour for donating blood. it is said that the donors of the plasma are hooked up to a small device that removes plasma while simultaneously returning red blood cells to their bodies. in regular blood donation, donors have to wait for red blood cells to replenish between donation but in the case of plasma, it can be donated frequently, which is twice a week.
the plasma rich with antibodies is taken from the recovered patients of COVID-19 and then is infused into the bloodstream of other infected coronavirus patients. when the body gets contact with external pathogens like bacteria or germs, it automatically starts a defense mechanism and started realizing antibodies.
According to the researchers, the therapy is not as simple as obtaining a significant amount of plasma from survivors is difficult. in the case of COVID-19, a new disease, where most patient is aged in already suffering from other diseases like hypertension, diabetes, etc. Therefore, effectiveness remains questionable.
