ABSTRACT
BACKGROUND:
COVID 19 infection caused by novel coronavirus with no specific established treatment. Convalescent Plasma Therapy has been authorized as an off-label therapeutic procedure. We assessed the outcome of convalescent plasma (CP) units versus standard treatment on the complete recovery, improvement and 28 days' mortality of COVID 19 patients. MATERIALS ANDMETHODS:
The present was multi-centric case controlled observational prospective study. The study was conducted for a period of four and half months from July 15 2020 to 30 November 2020 after taking approval from the Expert Committee, Health & Family Welfare Department, Government of Odisha. Plasma therapy was applied on two groups of 1189 serious COVID patients (959 number of pre- critical and 230 number of critical patients) not responding to oxygen therapy. It was compared with non- transfused control group of 1243 patients (996 number of pre-critical and 247 number of critical patients).RESULTS:
Discharge was better in (55.5%) transfused than (43%)in non-transfused pre-critical patients and the mortality was lower (44.3%) in transfused, (48.9%) than non-transfused critical patients respectively. Complete recovery was highest in those who were transfused with CP with neutralizing titer more than 1160 (52.5%), 18-30 years' age group (64%), females (53%), 'O' Rh D positive blood group (51.5%). There was no adverse reaction due to CP transfusion.CONCLUSIONS:
CP is effective in improving the recovery rate with earlier discharge and decrease in the 28 days' mortality than in the control non-transfused group. CP with neutralizing antibody titer more than 1160 has the best outcome with complete recovery and decrease in the mortality. It is more effective in treating pre-critical patients when transfused early, in female patients, in younger age group and in blood group 'O' Rh D positive.Keywords
