A patient with acute coronavirus appeared in Hyderabad as an experimental treatment consisting of convalescence plasma injections for passive immunization to treat the disease on Sunday noon.

The development was confirmed by Dr. Aftab Hussain Fall coordinator in the isolation room of LUH University Hospital.
The plasma donated by coronavirus patients retrieved to the Liaquat University Laboratory of Diagnostic Medicine and Health Sciences was given to a patient undergoing treatment in the isolation room.

He was given the plasma after managing his condition as best he could under certain conditions Fall said.
On April 30 the Sindh government allowed three regional hospitals to conduct clinical trials on the experimental use of Covid-19 syndrome for passive immunization.

Hospitals included Dr. Ruth Pfau Civil Hospital in Karachi the National Institute of Hematology (NIBD) in Karachi and LUH a government facility in Hyderabad.

Prior to that, the government had approved clinical trials for plasma therapy in addition to approving locally manufactured ventilators for treating seriously ill patients and granting permission to manufacture antiseptics and produce chloroquine.

Experimental treatment includes collecting blood from a person who has recovered from Covid-19 and transferring separate plasma to a seriously ill patient. Plasma is the obvious part of the blood that remains when blood cells are removed and contains antibodies and other proteins.

Antibody plasma transfer provides a form of negative immunity to the patient's recipient to fight infection. However, the protection provided by passive immunization is short-term and usually lasts only a few weeks or months.

The science behind plasma treatment and passive immunization are not new. This concept has been widely applied to treat various infectious diseases such as mumps measles and polio.
