| Abstrakt: | Objective: To determine whether high-dose dexamethasone increases the number of ventilator-free days (VFD) among patients with acute respiratory distress syndrome (ARDS) caused by COVID-19. Design: Multicenter, randomized, open-label, clinical trial. Participants: Consecutive patients with confirmed COVID-19-related ARDS were enrolled from June 17, 2020, to March 27, 2021, in four intensive care units (ICUs) in Argentina. Intervention: 16 mg of dexamethasone intravenously daily for five days followed by 8 mg of dexamethasone daily for five days or 6 mg of dexamethasone intravenously daily for 10 days. Main Outcome and Measures: The primary outcome was ventilator-free days during the first 28 days. The secondary outcomes were all-cause mortality at 28 and 90 days, infection rate, muscle weakness, and glycemic control in the first 28 days. Results: Data from 98 patients who received at least one dose of dexamethasone were analyzed. The trial was prematurely terminated due to low enrollment rate. At 28 days after randomization, there was no difference between high- and low-dose dexamethasone groups in VFD (median, 0 [interquartile range [IQR] 0-14] vs. 0 [IQR 0-1] days; P = .231), or in the mean duration of mechanical ventilation (19 ± 18 vs. 25 ± 22 days; P = .078). The cumulative hazard of successful discontinuation from mechanical ventilation was increased by the high-dose treatment (adjusted sub-distribution hazard ratio: 1.84; 95% CI: 1.31 to 2.5; P < .001). None of the prespecified secondary and safety outcomes showed a significant difference between treatment arms. Conclusions: Among patients with ARDS due to COVID-19, the use of higher doses of dexamethasone compared with the recommended low-dose treatment did not show an increase in VFD. However, the higher dose significantly improved the time required to liberate them from the ventilator. |
