“We are now going to select 350 COVID-19 patients under treatment at nine health facilities in the country and start clinical trials of convalescent plasma on them,” said the eminent hematologist.

Dr. Shamsi said the Drug Regulatory Authority of Pakistan had allowed medical professionals to start clinical trials of the use of convalescent plasma in entire Pakistan.

Following that, he added, the health departments of Punjab, KP, Balochistan, and Sindh had allowed them to use the technique known as passive immunization to treat patients infected with COVID-19.

Dr. Shamsi said the technique is used when there is a high risk of infection and insufficient time for the body to develop its own immune response or to reduce the symptoms of ongoing or immunosuppressive diseases.

“A team of health experts including hematologists, infectious disease specialists, intensivists (or ICU specialists), and a representative of the Sindh Blood Transfusion Authority will supervise the clinical trials at the three hospitals.”

He said that mainly patients undergoing treatment at the CHK in Karachi and the Liaquat University Hospital in Hyderabad would be given convalescent plasma with the hope of recovery from COVID-19.

Passive immunization is an old technique used in the absence of a vaccine to treat infectious diseases, he added.

He said these trials would also be conducted at the Hayatabad Medical Complex in Peshawar, the Shaikh Zayed Hospital in Quetta, the Pakistan Institute of Medical Sciences in Islamabad, the Benazir Bhutto Shaheed Hospital in Rawalpindi, and Lahore’s Pakistan Kidney & Liver Institute and Postgraduate Medical Institute.

Replying to a query, Dr. Shamsi said healthy COVID-19 patients who have tested negative twice can donate their blood for plasma extraction after two weeks of recovery, adding that with one donation, they can treat two such patients.

“The NIBD is equipped with four machines that can extract plasma from 40 patients a day,” he said. He believes the health of COVID-19 patients would start improving within 48 hours of undergoing treatment, and the patients would recuperate in the following six days.

“I appeal to all the healthy COVID-19 patients all over the country who have recovered from this disease to donate their blood so that the lives of others could be saved by using their plasma and antibodies.”
