Objectives: Convalescent plasma (CP) as a passive source of neutralizing antibodies and immunomodulators is a century-old therapeutic option used for the management of viral diseases. We investigated its effectiveness for the treatment of COVID-19. Design: Open-label, parallel-arm, phase II, multicentre, randomized controlled trial. Setting: Thirty-nine public and private hospitals across India. Participants: Hospitalized, moderately ill confirmed COVID-19 patients (PaO2/FiO2: 200-300 or respiratory rate > 24/min and SpO2 ≤ 93% on room air). Intervention: Participants were randomized to either control (best standard of care (BSC)) or intervention (CP + BSC) arm. Two doses of 200 mL CP was transfused 24 hours apart in the intervention arm. Main Outcome Measure: Composite of progression to severe disease (PaO2/FiO2<100) or all-cause mortality at 28 days post-enrolment. Results: Between 22 nd April to 14 th July 2020, 464 participants were enrolled; 235 and 229 in intervention and control arm, respectively. Composite primary outcome was achieved in 44 (18.7%) participants in the intervention arm and 41 (17.9%) in the control arm [aOR: 1.09; 95% CI: 0.67, 1.77]. Mortality was documented in 34 (13.6%) and 31 (14.6%) participants in intervention and control arm, respectively [aOR) 1.06 95% CI: -0.61 to 1.83]. Interpretation: CP was not associated with reduction in mortality or progression to severe COVID-19. This trial has high generalizability and approximates real-life setting of CP therapy in settings with limited laboratory capacity. A priori measurement of neutralizing antibody titres in donors and participants may further clarify the role of CP in management of COVID-19.

The natural history of COVID-19 infection in children is still evolving as the pandemic unfolds. Few cases of severe and often fatal COVID-19 have been reported although the infection is mild in the large majority. Children with cancers are recognised as a high risk group for all infections. Since there aren't any definite treatment guidelines established in children with severe COVID, treatment is guided by adult recommendations which too are often not evidence based. We report the case of a 4-year-old girl with severe COVID-19 associated pneumonia who presented to us as febrile neutropenia. The use of convalescent plasma along with steroids and IVIG showed dramatic results in this child and she recovered without the need for any specific treatment. This is highlighted as one of the earliest cases that is reporting the use of convalescent plasma in a child; the first ever in a child with underlying malignancy.

ObjectiveLarge data on the clinical characteristics and outcome of COVID-19 in the Indian population are scarce. We analysed the factors associated with mortality in a cohort of moderately and severely ill patients with COVID-19 enrolled in a randomised trial on convalescent plasma.DesignSecondary analysis of data from a Phase II, Open Label, Randomized Controlled Trial to Assess the Safety and Efficacy of Convalescent Plasma to Limit COVID-19 Associated Complications in Moderate Disease.Setting39 public and private hospitals across India during the study period from 22 April to 14 July 2020.ParticipantsOf the 464 patients recruited, two were lost to follow-up, nine withdrew consent and two patients did not receive the intervention after randomisation. The cohort of 451 participants with known outcome at 28 days was analysed.Primary outcome measureFactors associated with all-cause mortality at 28 days after enrolment.ResultsThe mean (SD) age was 51±12.4 years; 76.7% were males. Admission Sequential Organ Failure Assessment score was 2.4±1.1. Non-invasive ventilation, invasive ventilation and vasopressor therapy were required in 98.9%, 8.4% and 4.0%, respectively. The 28-day mortality was 14.4%. Median time from symptom onset to hospital admission was similar in survivors (4 days; IQR 3–7) and non-survivors (4 days; IQR 3–6). Patients with two or more comorbidities had 2.25 (95% CI 1.18 to 4.29, p=0.014) times risk of death. When compared with survivors, admission interleukin-6 levels were higher (p<0.001) in non-survivors and increased further on day 3. On multivariable Fine and Gray model, severity of illness (subdistribution HR 1.22, 95% CI 1.11 to 1.35, p<0.001), PaO2/FiO2 ratio <100 (3.47, 1.64–7.37, p=0.001), neutrophil lymphocyte ratio >10 (9.97, 3.65–27.13, p<0.001), D-dimer >1.0 mg/L (2.50, 1.14–5.48, p=0.022), ferritin ≥500 ng/mL (2.67, 1.44–4.96, p=0.002) and lactate dehydrogenase ≥450 IU/L (2.96, 1.60–5.45, p=0.001) were significantly associated with death.ConclusionIn this cohort of moderately and severely ill patients with COVID-19, severity of illness, underlying comorbidities and elevated levels of inflammatory markers were significantly associated with death.Trial registration numberCTRI/2020/04/024775.

Background:Despite its large population, access to safe blood is disproportionately low in India. To recruit more members from the general population into the pool of voluntary donors, it is essential to understand the differences in their knowledge, attitudes and practices; and utilise the existing resources to eliminate them. Methods:A quasi-experimental study was conducted on 180 donors and an equal number of potential donors randomly selected from the community, using a structured questionnaire containing questions on attitudes and practices. Knowledge was assessed by interview by a single observer.Results: Donors were found to have a highly significant difference (p<0.00001) from the general population in age, gender distribution, marital status and socioeconomic status and significant difference in educational level (p<0.05). Knowledge about blood donation practices was significantly higher in donors (p=0.0002). Replacement donors constituted 82.2% of the donor category, while voluntary donors dominated (52.3%) in the community. Commonest reasons for non-donation in both groups included apathy. Misconceptions regarding pain, weakness, and increased chances of infection were prevalent. Donors were less likely to perceive blood donation as risky (p<0.00001). There was a highly significant difference in the attitude towards incentives (p<0.00001), the donor group supporting and the community denouncing them. Replacement credits were the most popular incentive. In the donor group, a markedly higher (p=0.0003) proportion had a history of previous donations (55% vs.36.1%). Most of them had a higher number (p<0.00001) and greater frequency of donation. Donors generally reported a better donation experience (p=0.00003) and less complications than the general population (p=0.0002). Conclusions:There is a need to recruit women and young donors from the community, and promote donor retention. Blood donation drives play important role in creating awareness, educating the masses and dispelling myths and misconceptions.
