HYDERABAD: A critical coronavirus patient in Hyderabad has been administered an experimental therapy involving injecting convalescent plasma for passive immunisation to treat the disease, it emerged on Sunday.

The development was confirmed by the Liaquat University Hospital (LUH) isolation ward's focal person Dr Aftab Hussain Phull.

The plasma — donated by a recovered coronavirus patient to the Diagnostic and Research Laboratory at the Liaquat University of Medical and Health Sciences — was administered to a patient under treatment at the isolation ward.

"He was given the plasma after managing his condition as best as possible under the given circumstances," Phull said.

On April 30, the Sindh government had allowed three hospitals in the province to carry out clinical trials for the “experimental use of Covid-19 convalescent plasma for passive immunisation".

The hospitals included the Dr Ruth Pfau Civil Hospital in Karachi, the National Institute of Blood Diseases (NIBD) in Karachi and LUH, a government facility in Hyderabad.
