New Delhi: As the number of Coronavirus cases is set to breach 90 lakh mark, the Indian Council of Medical Research (ICMR) on Wednesday said sounded caution on indiscriminate use of Convalescent Plasma Therapy (CPT) against Covid-19 pandemic.
The Country’s top medical research body said that indiscriminate use of CPT should be avoided as it does not reduce mortality in COVID-19 patients.
“ICMR conducted an open-label phase II multicentre randomised controlled trial in India across 39 public and private hospitals on use of convalescent plasma in the management of cases with moderate COVID-19 disease (PLACID Trial). It was concluded that, CPT did not lead to reduction in progression to severe COVID19 or all cause mortality in the group that received CPT as compared to the group that did not receive CPT,” said ICMR in its new advisory.
“PLACID is the world’s largest pragmatic trial on CPT conducted in 464 moderately ill laboratory confirmed COVID-19 affected adults in real-world setting wherein no benefit of use of CPT could be established,” it said.
ICMR, in support of its advisory on plasma therapy, also mentioned about similar studies in China and Netherlands and said that there was no significant benefit of CPT in treating hospitalised COVID-19 patients.
“It is speculated that convalescent plasma having low concentration of specific antibody against SARS-CoV-2 may be less beneficial for treating COVID-19 patients as compared to plasma with high concentration of such antibodies,” said the guidance note.
“This ICMR advisory, therefore, embraces the principle that a potential donor for convalescent plasma should have sufficient concentration of antibody working against COVID19,” it added.
Who can donate plasma for Covid-19 patient treatment?
The ICMR’s advisory noted that a potential donor of CPT can be a male and female–who have never been pregnant can only donate plasma, it said.
The donor should be in the age group of 18-65 years who after 14 days of symptom resolution — testing negative for COVID-19 is not necessary, can donate plasma.
For the potential recipient, the ICMR said that donor can be in the early stage of COVID-19 and the therapy should be administered between 3-7 days from onset of symptoms, but not later than 10 days. There should be no IgG antibody against COVID-19 by appropriate test and informed consent has to be taken.
“CPT, therefore, should only be used, as advised by ICMR NTF, for management of COVID-19 when specific criteria are fulfilled,” it said.
The advisory came after Union Home Minister Amit Shah held a meeting to assess the COVID situation in Delhi wherein it was discussed to issue SoP for plasma therapy and plasma administration for treatment of COVID-19 patients immediately.
