Brief summary: Although the novel SARS-CoV-2 virus (COVD-19) is classified as an acute respiratory infection, emerging data show that morbidity and mortality are driven by disseminated intravascular coagulopathy. Untreated CAC leads to microangiopathic thromboses, causing multiple systems organ failure and consuming enormous healthcare resources. Identifying strategies to prevent CAC are therefore crucial to reducing COVID-19 hospitalization rates.

The pathogenesis of CAC is unknown, but there are major overlaps between severe COVID-19 and vitamin D insufficiency (VDI). We hypothesize that VDI is a major underlying contributor to CAC. Preliminary data from severe COVID-19 patients in New Orleans support this hypothesis. The purpose of the proposed multi-center, prospective, randomized controlled trial is to test the hypothesis that low-risk, early treatment with aspirin and vitamin D in COVID-19 can mitigate the prothrombotic state and reduce hospitalization rates.

Detailed description: Although the novel SARS-CoV-2 virus (COVD-19) is classified as an acute respiratory infection, emerging data show that morbidity and mortality are driven by disseminated intravascular coagulopathy. Data from Wuhan showed that COVID-19-associated coagulopathy (CAC) was present in 71% of deaths vs. 0.4% of survivors. Untreated CAC leads to microangiopathic thromboses, causing multiple systems organ failure and consuming enormous healthcare resources. Identifying strategies to prevent CAC are therefore crucial to reducing COVID-19 hospitalization rates.

The high prevalence of CAC in severely ill COVID-19 patients led the American Society of Hematology to recommend that all hospitalized COVID-19 patients be prophylactically anticoagulated. However, there are no data and no recommendations regarding outpatient prevention of CAC.

The pathogenesis of CAC is unknown. Given the demographic, geographic, pathologic, and treatment overlap between severe COVID-19 and vitamin D insufficiency (VDI), we hypothesize that VDI is a major underlying contributor to CAC. Preliminary data from critically ill COVID-19 patients in New Orleans support this hypothesis. Furthermore, mouse models of VDI developed aggravated multiorgan thrombus formation after lipopolysaccharide injection; this phenotype parallels CAC.

Given these lines of evidence, the purpose of the proposed multi-center, prospective, randomized controlled trial is to test the hypothesis that low-risk, early treatment with aspirin and vitamin D in COVID-19 (The LEAD COVID-19 Trial) can mitigate the prothrombotic state and reduce hospitalization rates.
