摘要信息：Objective: Neutrophil elastase (NE) plays an important role in the development of acute respiratory distress syndrome (ARDS). Sivelestat sodium, as a selective NE inhibitor, may improve the outcomes of patients with sepsis-induced ARDS in previous studies, but there is a lack of solid evidence. This trial aimed to evaluate the effect of sivelestat sodium on oxygenation in patients with sepsisinduced ARDS. Methods: We conducted a multicenter, double-blind, randomized, placebo-controlled trial enrolling patients diagnosed with sepsisinduced ARDS admitted within 48 hours of the advent of symptoms. Patients were randomized in a 1:1 fashion to sivelestat or placebo. Trial drugs were administered as a 24-hour continuous intravenous infusion, for a minimum duration of 5 days and a maximum duration of 14 days. The primary outcome was the proportion of PaO2/FiO2 ratio improvement on Day 5 after randomization, deffned by a greater than 50% improvement in PaO2/FiO2 compared with that on ICU admission or PaO2/FiO2 reached over 300 mmHg on Day 5. Results: The study was stopped midway due to a potential between-group difference in mortality observed during the interim analysis. Overall, a total of 70 patients were randomized, of whom 34 were assigned to receive sivelestat sodium and 36 placebo. On day 5, 19/ 34 (55.9%) patients in the sivelestat group had PaO2/FiO2 ratio improvement compared with 7/36 (19.4%) patients in the placebo group (risk difference, 0.36; 95% CI, 0.14 to 0.56, p<0.001). The Kaplan–Meier curves showed a signiffcantly improved 28-day survival rate in patients receiving sivelestat than those not (hazard ratio, 0.32; 95% CI, 0.11 to 0.95; p=0.041). Conclusion: In patients with sepsis-induced ARDS, sivelestat sodium could improve oxygenation within the ffrst ffve days and may be associated with decreased 28-day mortality.

摘要信息：Background. Since the 2012 Berlin Definition of the Acute Respiratory Distress Syndrome (ARDS), several developments have supported the need for an expansion of the definition, including the use of high flow nasal oxygen (HFNO), expanding use of pulse oximetry in place of arterial blood gases, use of ultrasound for chest imaging, and the need for applicability in resource-limited settings. Methods. A Consensus Conference of 32 critical care ARDS experts was convened, had six virtual meetings (June 2021-March 2022), and subsequently obtained input from members of several critical care societies. The goal was to develop a definition that would: (1) identify patients with the currently accepted conceptual framework for ARDS; (2) facilitate rapid ARDS diagnosis for clinical care and research; (3) be applicable in resource-limited settings; (4) be useful for testing specific therapies; and (5) be practical for communication to patients and caregivers. Results. The committee made four main recommendations: (1) Include HFNO with a minimum flow rate of  30 liters/min; (2) Use arterial oxygen tension (PaO2)/FiO2  300 mmHg or SpO2/FiO2 < 315 (if SpO2  97%) to identify hypoxemia; (3) Retain bilateral opacities for imaging criteria but add ultrasound as an imaging modality, especially in resource-limited areas; and (4) In resource-limited settings, do not require PEEP, oxygen flow rate, or specific respiratory support devices. Conclusions. We propose a New Global Definition of ARDS that builds on the Berlin Definition. The recommendations also identify areas for future research, including the need for prospective assessments of feasibility, reliability, and prognostic validity of the proposed Global Definition.

摘要信息：Objective:We aimed to evaluate the protective effects of sivelestat sodium on the basis of corticosteroid therapy in patients with moderate-to-severe acute respiratory distress syndrome (ARDS).Methods:We retrospectively investigated 127 patients with confirmed moderate-to-severe ARDS treated in the intensive care unit (ICU) at Dazhou Central Hospital. Patients were divided into the control group (corticosteroids alone) and the combination therapy of steroids and sivelestat sodium (CTSSS) group according to the therapeutic interventions. The primary outcome was in-hospital mortality. And the baseline characteristics and laboratory findings of patients were collected for analysis.Results:The overall mortality rate in 127 patients was 48.8%. There was no statistically significant difference in in-hospital mortality between the CTSSS group and the control group (45.3% vs. 56.1%). In the subgroup of patients aged < 80 years or with an Acute Physiology and Chronic Health Evaluation (APACHE) II score < 30, CTSSS could reduce the risk of mortality (odds ratio [OR] = 0.41, 95% confidence interval [CI], 0.17-0.96, p=0.041; OR = 0.31, 95% CI, 0.13-0.77, p=0.012; respectively). Among patients aged 80 years or older, those with CTSSS exhibited a significantly elevated risk of mortality (OR = 13; 95% CI, 1.20-140.73; p=0.035).Conclusion:Compared with corticosteroids alone, CTSSS could improve oxygenation index, increase lymphocyte count, protect extrapulmonary organs and reduce in-hospital mortality rate in patients with moderate-to-severe ARDS in specific subgroups (age < 80 years or APACHE II score < 30). It might be advisable to avoid CTSSS in moderate-to-severe ARDS patients aged 80 years or older. Prospective studies involving larger sample sizes are needed to verify these findings.

摘要信息：Background Recent studies suggest that neutrophil elastase inhibitor (Sivelestat) may improve pulmonary function and reduce mortality in patients with acute respiratory distress syndrome. We examined the association between receipt of sivelestat and improvement in oxygenation among patients with acute respiratory distress syndrome (ARDS) induced by COVID-19. Methods A large multicentre cohort study of patients with ARDS induced by COVID-19 who had been admitted to intensive care units (ICUs). We used propensity score matching to compare the outcomes of patients treated with sivelestat to those who were not. The diferences in continuous outcomes were assessed with the Wilcoxon signed-rank test. Kaplan–Meier method was used to show the 28-day survival curves in the matched cohorts. A log-rank P-test stratifed on the matched pairs was used to test the equality of the estimated survival curves. A Cox proportional hazards model that incorporated a robust sandwich-type variance estimator to account for the matched nature of the data was used to estimate hazard ratios (HR). All statistical analyses were performed with SPSS 26.0 and R 4.2.3. A two-sided p-value of < 0.05 was considered statistically signifcant. Results A total of 387 patients met inclusion criteria, including 259 patients (66.9%) who were treated with sivelestat. In 158 patients matched on the propensity for treatment, receipt of sivelestat was associated with improved oxygenation, decreased Murray lung injury score, increased non-mechanical ventilation time within 28 days, increased alive and ICU-free days within 28 days (HR, 1.85; 95% CI 1.29 to 2.64; log-rank p < 0.001), shortened ICU stay and ultimately improved survival (HR, 2.78; 95% CI 1.32 to 5.88; log-rank p = 0.0074). Conclusions Among patients with ARDS induce by COVID-19, sivelestat administration is associated with improved clinical outcomes.
