摘 要：Background:The benefits and harms of methylprednisolone treatment in patients with moderate coronavirus disease 2019(COVID-19)remain controversial.In this study,we investigated the effect of methylprednisolone on mortality rate,viral clearance,and hospitalization stay in patients with moderate COVID-19.Methods:This retrospective study included 4827 patients admitted to Wuhan Huoshenshan and Wuhan Guanggu hospitals from February to March 2020 diagnosed with COVID-19 pneumonia.The participants’epidemiological and demographic data,comorbidities,laboratory test results,treatments,outcomes,and vital clinical time points were extracted from electronic medical records.The primary outcome was in-hospital death;secondary outcomes were time from admission to viral clearance and hospital stay.Univariate and multivariate logistic or linear regression analysis were used to assess the roles of methylprednisolone in different outcomes.The propensity score matching(PSM)method was used to control for confounding factors.Results:A total of 1320 patients were included in this study,of whom 100 received methylprednisolone.Overall,in-hospital mortality was 0.91%(12/1320);the 12 patients who died were all in the methylprednisolone group,though multivariate logistic regression analysis showed methylprednisolone treatment was not a risk factor for in-hospital death in moderate patients before or after adjustment for confounders by PSM.Methylprednisolone treatment was correlated with longer length from admission to viral clearance time and hospital stay before and after adjustment for confounders.Conclusions:Methylprednisolone therapy was not associated with increased in-hospital mortality but with delayed viral clearance and extended hospital stay in moderate COVID-19 patients.
