IMPACT OF METHYLPREDNISOLONE PULSE ON THE MORTALITY OF PATIENTS WITH ACUTE RESPIRATORY DISTRESS SYNDROME SECONDARY TO COVID-19 (preprint)

Corticosteroids are the most important factor to reduce the mortality in patients with moderate-severe COVID-19. The aim of the study was to analyze the impact of methylprednisolone pulse (MPP) on in-hospital mortality of patients with acute respiratory distress syndrome (ARDS) due to COVID-19. We conducted a retrospective, single-center observational study We selected adult patients admitted to the hospital with the diagnosis of COVID-19 between March and June 2020. A total of 306 patients were analyzed. In-hospital crude mortality rate was 17%. Diabetes mellitus (HR 5.5, 95% CI 1.40–4.55), dementia (HR 7.7, 95% CI 4.25-13.87) and ARDS (HR 4.2, 95% CI 2.34-7.46) were associated with in -hospital mortality. In patients diagnosed of ARDS, the only in-hospital mortality risk factor was dementia (HR 5.2, 95% CI 2.44–11.07), whereas MPP was a protective factor (HR 0.2, 95% CI 0.09–0.63)

Early Covid-19 Treatment With SARS-CoV-2 Neutralizing Antibody Sotrovimab (preprint)

Background: Coronavirus disease 2019 (Covid-19) disproportionately results in hospitalization and death in older patients and those with underlying comorbidities. Sotrovimab is a pan-sarbecovirus monoclonal antibody designed to treat such high-risk patients early in the course of disease, thereby preventing Covid-19 progression. Methods: In this ongoing, multicenter, double-blind, phase 3 trial, nonhospitalized patients with symptomatic Covid-19 and at least one risk factor for disease progression were randomized (1:1) to an intravenous infusion of sotrovimab 500 mg or placebo. The primary efficacy endpoint was the proportion of patients with Covid-19 progression, defined as hospitalization longer than 24 hours or death, through day 29. Results: In this preplanned interim analysis, which included an intent-to-treat population of 583 patients (sotrovimab, 291; placebo, 292), the primary efficacy endpoint was met. The risk of Covid-19 progression was significantly reduced by 85% (97.24% confidence interval, 44% to 96%; P = 0.002) with a total of three (1%) patients progressing to the primary endpoint in the sotrovimab group versus 21 (7%) patients in the placebo group. All five patients admitted to intensive care, including one who died by day 29, received placebo. Safety was assessed in 868 patients (sotrovimab, 430; placebo, 438). Adverse events were reported by 17% and 19% of patients receiving sotrovimab and placebo, respectively; serious adverse events were less common with sotrovimab (2%) versus placebo (6%). Conclusion: Sotrovimab reduced progression of Covid-19 in patients with mild/moderate disease, was well tolerated, and no safety signals were identified.
