Context:

  • The use of convalescent plasma has been dropped from the recommended treatment guidelines for COVID-19, according to an advisory from the Indian Council of Medical Research (ICMR).

About:

  • Though a trial by the ICMR on 400 patients last year — called the PLACID trial — had found no significant benefit from the use of plasma, it continued to find a place in the recommended guidelines.
  • Some experts have said the use of such plasma may have even played a role in facilitating new worrisome mutations to the virus.

Plasma therapy:

  • Blood plasma is a yellowish liquid component of blood that holds the blood cells of whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume.
  • This plasma contains viral antibodies that have treatment potential for severe cases of the disease.
  • Plasma therapy is a medical procedure that uses the blood of a recovered patient to create antibodies on those infected individuals.
  • Medically known as convalescent plasma therapy, this treatment uses antibodies found in the blood taken from a recovered Covid-19 patient. It is then used to treat those with severe SARS-CoV-2 infection to aid recovery.
