摘要信息:Background:Acute lung injury (ALI) is one of the most common critical illnesses in clinical practice, with sepsis being the most common cause of ALI. Sivelestat sodium (SV) hydrate is a highly effective inhibitor of neutrophil elastase, specifically targeting ALI related to systemic inflammatory response syndrome. The aim of this study is to examine the mechanisms by which SV can reduce the severity of ALI resulting from sepsis. Methods:Cecum ligation and puncture (CLP) was employed for creating an animal model of ALI caused by sepsis. Primary human pulmonary microvascular endothelial cells (HPMECs) were treated with lipopolysaccharide (LPS) to develop an in vitro model of infection-induced ALI. Lung tissue damage was assessed by employing hematoxylin-eosin (H&E) and Masson staining. Lung edema was determined by calculating the lung wet-to-dry weight ratio. Lung tissue and cell samples were analyzed using Enzyme-linked immunosorbent assay (ELISA) to detect levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6. The 5-ethynyl-2'-deoxyuridine (EdU) and wound-healing assay were used to determine the cell proliferation and migration, while flow cytometry was used for detecting cell apoptosis. The association between microRNA (miR)-744 and transforming growth factor (TGF)-β1 was discovered and confirmed through the utilization of bioinformatics analyses and dual-luciferase gene reporter assay. The analysis of TGF-β1, p-Smad3, and Smad3 was carried out through western blotting and immunohistochemistry in both in vitro and in vivo scenarios. Results:In both in vivo and in vitro settings of ALI models of sepsis, there was a significant decrease in the level of miR-744-5p, a significant elevation in the expression of inflammatory factors, and a significant intensification of lung tissue damage. Administration of SV resulted in a significant increase in the level of miR-744-5p, suppressed the inflammatory response, and ultimately improved lung injury. Cell proliferation was significantly enhanced by SV and cell apoptosis was inhibited. The protection of SV was significantly reversed by inhibiting the effect of miR-744-5p. The double-luciferase reporter gene assay revealed substantial interactions occurring between miR-744-5p and TGF-β1. The TGF-β/Smad signaling pathway was significantly inhibited by SV, however, the inhibitory effect can be counteracted by utilizing the miR-744-5p inhibitor. Conclusions:The upregulation of miR-744-5p by SV inhibits the TGF-β/Smad signaling pathway, thereby reducing sepsis-induced ALI.

摘要信息:Background:Sivelestat, a neutrophil elastase inhibitor, is postulated to mitigate acute lung injury in patients following emergency surgery. However, its efficacy in patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) induced by coronavirus disease 2019 (COVID-19) remains uncertain. This study aims to evaluate the pulmonary protective effects of sivelestat in COVID-19 patients with ALI/ARDS. Methods:A retrospective study was conducted involving 2454 COVID-19 patients between October 5, 2022, and February 1, 2023. Of these, 102 patients received sivelestat (0.2 mg/kg/h), while 2352 age- and sex-matched controls were identified. Propensity score matching (PSM) analysis was used to match sivelestat and non-sivelestat subgroups in ratios of 1:1 and 1:3 for sensitivity analysis. The primary outcome was a composite of effective outcomes, including 30-day mortality. Secondary outcomes included changes in partial pressure of arterial oxygen (PaO2), the ratio of PaO2to the fraction of inspired oxygen (PaO2/FiO2), and various cytokine levels. Safety evaluations included assessments of liver function, kidney function, and leukopenia. Results:In the propensity score-matched analysis, the sivelestat group had a higher proportion of severe/critical patients (87.26 % vs. 51.02 %, P < 0.001), more ARDS patients (4.9 % vs. 0.43 %, P < 0.001), and more patients with interstitial lung disease (4.9 % vs. 1.49 %, P = 0.023), but fewer patients with stroke (17.65 % vs. 19.86 %, P < 0.001). Oxygen therapy rates were similar between the groups (79.41 % vs. 80.95 %, P = 0.9). The relative risk reduction in 30-day mortality was 88.45 % (95 % confidence interval [CI] 81.23%-93.21 %) for severe/critical COVID-19 patients treated with sivelestat. Sivelestat significantly decreased cytokine levels of interferon alpha (IFNα), interleukin-1 beta (IL-1β), and interleukin-2 (IL-2).In the sivelestat group, the mortality rate was significantly reduced with standard oxygenation and HFNC therapy(P < 0.05). The treatment with sivelestat did not increase side effects. Conclusion:The administration of the neutrophil elastase inhibitor sivelestat may improve clinical outcomes in COVID-19 patients with ALI/ARDS. These findings suggest that sivelestat could be considered an effective treatment option to alleviate pulmonary inflammatory injury caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
