Background: The role of convalescent plasma (COPLA) for the treatment of severely ill Corona Virus Disease-2019 is under investigation. We compared the efficacy and safety of convalescent plasma with fresh frozen plasma (FFP) in severe COVID-19 patients.
Methods and findings: This was an open-label, single-centre phase II RCT on 29 patients with severe COVID-19 from India. One group received COPLA with standard medical care (SMC) (n=14), and another group received FFP with SMC (n=15). A total of 29 patients were randomized in the two treatment groups. Eleven out of 14 (78.5%) patients remained free of ventilation at day seven in the intervention arm while the proportion was 14 out of 15 (93.3 %) in the control arm (p= 0.258). The median reductions in RR per min at 48-hours in COPLA-group and FFP group were -6.5 and -3 respectively [p=0.004] and at day seven were -14.5 and -10 respectively (p=0.008). The median improvements in percentage O2 saturation at 48-hours were 6.5 and 2 respectively [p=0.001] and at day seven were 10 and 7.5 respectively (p=0.026). In the COPLA-group, the median improvement in PaO2/FiO2 was significantly superior to FFP at 48-hours [41.94 and 231.15, p=0.009], and also at day-7 [5.55 and 77.01 p<0.001]. We did not find significant differences in hospitalization duration between the groups (0.08).
Conclusion: COPLA therapy resulted in rapid improvement in respiratory parameters and shortened time to clinical recovery, although no significant reduction in mortality was observed in this pilot trial. We need larger trials to draw conclusive evidence on the use of Convalescent plasma in COVID-19.
1 In a double‐blind crossover study, flurbiprofen produced marked relief of pain which was significantly more than with aspirin and placebo in patients suffering from primary dysmenorrhoea. In contrast, there was no significant difference between the relief of pain obtained with aspirin and placebo. 2 The clinician's overall assessment of efficacy also indicated that flurbiprofen produced better response as compared to aspirin and placebo in these patients with dysmenorrhoea. 3 Both flurbiprofen and aspirin did not produce any apparent adverse effects on blood loss during the menstrual period. 4 In conclusion, the analgesic effect of flurbiprofen seen in this trial establishes the therapeutic usefulness of the drug in the treatment of primary dysmenorrhoea.
background: Role of Convalescent plasma (COPLA) to treat severe COVID-19 is under investigation. We compared effi cacy and safety of COPLA with fresh frozen plasma (FFP) in severe COVID-19 patients. Methods: One group received COPLA with standard medical care (n = 14), and another group received random donor FFP, as control with standard medical care (n = 15) in severe COVID-19 disease. Results: The proportion of patients free of ventilation at day seven were 78.5% in COPLA group, and 93.3 % in control group were not signifi cant (p= 0.258). However, improved respiratory rate, O2 saturation, SOFA score, and Ct value were observed in the COPLA group. No serious adverse events were noticed by plasma transfusion in both groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
