Adjunctive Corticosteroids for COVID-19: A Retrospective Cohort Study

ABSTRACT Background Coronavirus disease 2019 (COVID-19) is associated with severe pneumonia, respiratory failure and death. We aim to evaluate the efficacy of adjunctive corticosteroids in the management of COVID-19.Methods This is a retrospective cohort study of hospitalized adults (≥18 years) who were diagnosed with COVID-19 and were given treatment. Treatment included hydroxycholoroquine and lopinavir-ritonavir. Corticosteroids were included as adjunctive therapy in mid-April, 2020. We compared composite outcomes of clinical progression and invasive mechanical ventilation (MV) or death between group that received treatment only (Group A) versus group that received adjunctive corticosteroids (Group B). Entropy balancing was used to generate stabilized weight for covariates between treatment groups. Unweighted Kaplan-Meir curves, weighted and adjusted Cox regression analysis were used to estimate effect of adjunctive corticosteroids on composite outcomes. Subgroup analysis was performed on those with pneumonia.Results Of 1046 patients with COVID-19, 57 received treatment alone (Group A) and 35 received adjunctive corticosteroids in addition to treatment (Group B). Median day of illness at treatment initiation was 5 day. There were 44 patients with pneumonia; 68.9% of them were not requiring supplemental oxygen at treatment initiation. Overall, 17 (18.5%) of 92 patients had clinical progression including 13 (22.8%) of 57 patients in Group A versus 4 (11.4%) of 35 patients in Group B (p=0.172). Unweighted Kaplan-Meier estimates showed no significant difference in the proportion of patients who had clinical progression or invasive MV or death between the 2 treatment groups. However in those with pneumonia, there were lower proportions of patients in Group B with clinical progression (11.1%, 95% CI 0.0 - 22.2 versus 58.8%, 95% CI 27.3 - 76.7, log rank p<0.001); and invasive MV or death (11.3%, 95% CI 0.0 - 22.5 versus 41.2%, 95% CI 12.4. - 60.5, log rank p=0.016). In weighted and adjusted cox regression analysis, patients in Group B were less likely to have clinical progression, (adjusted HR [aHR] 0.08, 95% CI 0.01-0.99, p=0.049) but there was no statistical significant difference in risk of requiring invasive MV or death (aHR 0.22, 95%CI 0.02 - 2.54, p=0.22). In subgroup with pneumonia, patients in Group B were significantly at lower risk of clinical progression (aHR 0.15, 95% CI 0.06 - 0.39, p<0.001) and requiring invasive MV compared to Group A (aHR 0.30, 0.10-0.87, p=0.029).Conclusions Use of adjunctive corticosteroids is associated with lower risk of clinical progression and invasive MV or death, especially in those with pneumonia. Concurrent use of antivirals and corticosteroids should be considered in the management of COVID-19 related pneumonia..
