ABSTRACT
The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an unprecedented event requiring frequent adaptation to changing clinical circumstances. Convalescent immune plasma (CIP) is a promising treatment that can be mobilized rapidly in a pandemic setting. We tested whether administration of SARS-CoV-2 CIP at hospital admission could reduce the rate of ICU transfer or 28-day mortality or alter levels of specific antibody responses before and after CIP infusion. In a single-arm phase II study, patients >18 years-old with respiratory symptoms with confirmed COVID-19 infection who were admitted to a non-ICU bed were administered two units of CIP within 72 h of admission. Levels of SARS-CoV-2 detected by PCR in the respiratory tract and circulating anti-SARS-CoV-2 antibody titers were sequentially measured before and after CIP transfusion. Twenty-nine patients were transfused high titer CIP and 48 contemporaneous comparable controls were identified. All classes of antibodies to the three SARS-CoV-2 target proteins were significantly increased at days 7 and 14 post-transfusion compared with baseline (P < 0.01). Anti-nucleocapsid IgA levels were reduced at day 28, suggesting that the initial rise may have been due to the contribution of CIP. The groups were well-balanced, without statistically significant differences in demographics or co-morbidities or use of remdesivir or dexamethasone. In participants transfused with CIP, the rate of ICU transfer was 13.8% compared to 27.1% for controls with a hazard ratio 0.506 (95% CI 0.165-1354), and 28-day mortality was 6.9% compared to 10.4% for controls, hazard ratio 0.640 (95% CI 0.124-3.298). IMPORTANCE Transfusion of high-titer CIP to non-critically ill patients early after admission with COVID-19 respiratory disease was associated with significantly increased anti-SARSCoV-2 specific antibodies (compared to baseline) and a non-significant reduction in Ku transfer and death (compared to controls). This prospective phase II trial provides a suggestion that the antiviral effects of CIP from early in the COVID-19 pandemic may delay progression to critical illness and death in specific patient populations. This study informs the optimal timing and potential population of use for CIP in COVID-19, particularly in settings without access to other interventions, or in planning for future coronavirus pandemics.
ABSTRACT
The coronavirus pandemic precipitated an economic crisis disproportionately affecting renter households. Attempting to prevent a surge in evictions, policy makers at the federal, state, and local levels extended emergency protections to renters. The authors describe eviction filing patterns in 2020 and analyze the efficacy of eviction moratoria. New filings were reduced dramatically since the start of the pandemic. Between March 15 and December 31, 2020, across sites for which data are available, 65 percent fewer eviction cases were filed than would be expected in a typical year. Extrapolating nationwide, the authors estimate that at least 1.55 million fewer eviction cases were filed in 2020 than in a normal year. The pace at which cases were filed increased in late 2020, however, and the amount of back rent claimed grew considerably. Filing rates exceeded historical averages when protections lapsed. Black and female renters received a disproportionate share of eviction cases filed during the pandemic. © The Author(s) 2021.
