RESUMO
ObjectiveTo assess the effectiveness of corticosteroids among elderly patients with COVID-19 pneumonia requiring oxygen. DesignComparative observational study based on routine care data. Baseline characteristics of patients were balanced using propensity-score inverse probability of treatment weighting. SettingGeriatric and infectious diseases wards from 36 hospitals in France and Luxembourg. ParticipantsAdults > 80 years old PCR confirmed SARS-CoV-2 infection or typical CT-scan images, requiring oxygen [≥] 3L/min and with an inflammatory syndrome (C-reactive protein [≥] 40mg/L). MeasurementsThe primary outcome was overall survival at day 14. The secondary outcome was the proportion of patients discharged from hospital to home/rehabilitation on day 14. Adverse events were abstracted from electronic health records. ResultsAmong the 267 patients included in the analysis, 96 were assigned to the treatment group. Median age was 86, interquartile range 83 to 90 and 95% had a SARS-CoV-2 PCR-confirmed diagnosis. Use of corticosteroids was significantly associated with an increased survival (weighted hazard ratio [wHR] 0.66, 95% CI 0.44 to 0.97). There was no significant difference between the treatment and control groups regarding the proportion of patients discharged to home/rehabilitation at day 14 (wRR 1.11, 95% CI 0.68 to 1.81). Twenty-two (16.7%) patients receiving corticosteroids developed adverse events while only 11 (6.4%) from the control group did. ConclusionsCorticosteroids were associated with a significant increase the day-14 overall survival of patients over 80 years old hospitalized for severe COVID-19. Impact statementWe certify that this work is novel. As of today, studies on the efficacy of corticosteroids did not specifically target elderly patients. Among older patients aged over 80 years old, the RECOVERY trial found no difference in the survival of patients treated or not with dexamethasone. However, the heterogeneity in the severity of infection within the latter subgroup limited the drawing of strong conclusions
RESUMO
Objective To assess the effectiveness of corticosteroids on outcomes of patients with mild COVID-19 pneumonia. Methods We used routine care data from 51 hospitals in France and Luxembourg to assess the effectiveness of corticosteroids at 0.8 mg/kg/day eq. prednisone (CTC group) vs standard of care (no-CTC group) among patients [≤] 80 years old with COVID-19 pneumonia requiring oxygen without mechanical ventilation. The primary outcome was intubation or death at Day 28. Baseline characteristics of patients were balanced using propensity score inverse probability of treatment weighting. Results Among the 891 patients included in the analysis, 203 were assigned to the CTC group. At day 28, corticosteroids did not reduce the rate of the primary outcome (wHR 0.92, 95% CI 0.61 to 1.39) nor the cumulative death rate (wHR 1.03, 95% CI 0.54 to 1.98). Corticosteroids significantly reduced the rate of the primary outcome for patients requiring oxygen [≥] at 3L/min (wHR 0.50, 95% CI 0.30 to 0.85) or C-Reactive Protein (CRP) [≥] 100mg/L (wHR 0.44, 95%CI 0.23 to 0.85). We found a higher number of hyperglycaemia events among patients who received corticosteroids, but number of infections were similar across the two groups. Conclusions We found no association between the use of corticosteroids and intubation or death in the broad population of patients [≤]80 years old with COVID-19 hospitalized in non-ICU settings. However, the treatment was beneficial for patients with [≥] 3L/min oxygen or CRP [≥] 100mg/L at baseline. These data support the need to confirm the right timing of corticosteroids for patients with mild COVID.
RESUMO
BackgroundTreatments are urgently needed to prevent respiratory failure and deaths from coronavirus disease 2019 (COVID-19). Hydroxychloroquine (HCQ) has received worldwide attention because of positive results from small studies. MethodsWe used data collected from routine care of all adults in 4 French hospitals with documented SARS-CoV-2 pneumonia and requiring oxygen [≥] 2 L/min to emulate a target trial aimed at assessing the effectiveness of HCQ at 600 mg/day. The composite primary endpoint was transfer to intensive care unit (ICU) within 7 days from inclusion and/or death from any cause. Analyses were adjusted for confounding factors by inverse probability of treatment weighting. ResultsThis study included 181 patients with SARS-CoV-2 pneumonia; 84 received HCQ within 48 hours of admission (HCQ group) and 97 did not (no-HCQ group). Initial severity was well balanced between the groups. In the weighted analysis, 20.2% patients in the HCQ group were transferred to the ICU or died within 7 days vs 22.1% in the no-HCQ group (16 vs 21 events, relative risk [RR] 0.91, 95% CI 0.47-1.80). In the HCQ group, 2.8% of the patients died within 7 days vs 4.6% in the no-HCQ group (3 vs 4 events, RR 0.61, 95% CI 0.13-2.89), and 27.4% and 24.1%, respectively, developed acute respiratory distress syndrome within 7 days (24 vs 23 events, RR 1.14, 95% CI 0.65-2.00). Eight patients receiving HCQ (9.5%) experienced electrocardiogram modifications requiring HCQ discontinuation. InterpretationThese results do not support the use of HCQ in patients hospitalised for documented SARS-CoV-2-positive hypoxic pneumonia.
