what is Plasma Therapy?
what is plasma?
what is antibody?
what is the triviality?

Several countries, including India, are seriously looking at plasma therapy as a potential treatment for Covid-19, the disease caused by the novel coronavirus. Plasma therapy uses blood donated by recovered patients to introduce antibodies in those under treatment. 

What is plasma 
Plasma is the liquid portion of whole blood. It is composed largely of water and proteins, and it provides a medium for red blood cells, white blood cells and platelets to circulate through the body.
 
what is an antibody??
a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.


After China and the US, India has given a go ahead for framing a protocol to conduct a clinical trial for convalescent plasma therapy. The therapy has been used experimentally in the past and so has become a ray of hope in the fight against the novel coronavirus pandemic.

The convalescent plasma therapy aims at using antibodies from the blood of a recovered Covid-19 patient to treat those critically affected by the virus. The therapy can also used to immunise those at a high risk of contracting the virus -- such as health workers, families of patients and other high-risk contacts.

This therapy's concept is simple and is based on the premise that the blood of a patient who has recovered from Covid-19 contains antibodies with the specific ability of fighting novel coronavirus. The theory is that the recovered patient's antibodies, once ingested into somebody under treatment, will begin targetting and fighting the novel coronavirus in the second patient.

The convalescent plasma therapy uses antibodies developed within an infected person while he/she is infected with the novel coronavirus.

These antibodies are developed in a patient as part of the body's natural immune response to a foreign pathogen or in this case, the novel coronavirus. These antibodies are highly specific to the invading pathogen and so, work to eliminate the novel coronavirus from the patient's body.

Once the patient has recovered, they donate their blood so that their antibodies can be used to treat other patients. The donated blood is then checked for the presence of any other disease-causing agents such as Hepatitis B, Hepatitis C, HIV etc.

If deemed safe, the blood is then taken through a process to extract 'plasma', the liquid part of the blood that contains antibodies. The antibody-rich plasma, once extracted, is then ingested into the body of a patient under treatment.

Besides speaking about the success of the convalescent plasma therapy, the study by John Hopkins immunologists stated some of the risks associated with it:

1. Transfer of blood substances: As the blood transfusion takes place, there are risks that an inadvertent infection might get transferred to the patient.

2. Enhancement of infection: The therapy might fail for some patients and can result in an enhanced form of the infection.

3. Effect on immune system: The antibody administration may end up suppressing the body's natural immune response, leaving a Covid-19 patient vulnerable to subsequent re-infection.
