Effect of Neutrophil Elastase Inhibitor (Sivelestat Sodium) on Oxygenation in Patients with Sepsis-Induced Acute Respiratory Distress 
Syndrome
Effect of Neutrophil Elastase Inhibitor (Sivelestat Sodium) on Oxygenation in Patients with Sepsis-Induced Acute Respiratory Distress Syndrome

文章来源:PubMed

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. Keywords: sepsis, acute respiratory distress syndrome, neutrophil elastase, sivelestat, oxygenation

A New Global Definition of Acute Respiratory Distress Syndrome
A New Global Definition of Acute Respiratory Distress Syndrome

文章来源:PubMed

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.

The Protective Effects of Sivelestat Sodium on the Basis of Corticosteroid Therapy in Patients With Moderate-to-Severe Acute Respiratory Distress Syndrome
The Protective Effects of Sivelestat Sodium on the Basis of Corticosteroid Therapy in Patients With Moderate-to-Severe Acute Respiratory Distress Syndrome

文章来源:PubMed

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.

Population pharmacokinetics of sivelestat in Chinese patients with severe pneumonia(在中国重症肺炎患者中的群体药代动力学)

文章来源:PubMed

摘要信息:背景:缺血再灌注损伤(IRI)常导致肾脏损害。虽然中性粒细胞胞外陷阱(NETs)的存在一直被观察到,但它们对IRI的具体影响尚未确定。西维来司他钠是中性粒细胞弹性酶的抑制剂,对NET的形成至关重要,可能为肾脏IRI提供治疗方法,值得进一步研究。 方法:建立小鼠早期肾IRI模型,经损伤标志物和组织学检查证实。免疫荧光和Western blot证实NETs在肾I/R中的作用。通过一套全面的方法进一步评估肾功能和病理,包括周期性酸希夫染色(PAS)和末端脱氧核苷酸转移酶dUTP Nick末端标记(TUNEL)染色,酶联免疫吸附试验(ELISA),实时肾小球滤过率(RT-GFR)监测,聚合酶链反应(PCR),生化分析,以及额外的Western blot和免疫荧光试验。 结果:我们首先量化了肾IRI小鼠的NET表达,并在24小时达到峰值。随后,给予西维来司他钠治疗,导致MPO、CitH3降低,并减轻了肾小管损伤。此外,它还导致血清肌酐、血尿素氮(BUN)、中性粒细胞明胶酶相关脂钙蛋白(NGAL)和肾损伤分子-1 (KIM-1)水平降低。降低肾组织炎症标志物白介素-6 (IL-6)和肿瘤坏死因子-α (TNF-α)的丰度,减轻氧化应激指标丙二醛(MDA)和4羟基烯醛(4HNE)的水平,并伴有肾I/R小鼠肾细胞凋亡减少和GFR升高。 结论:西维来司他钠通过下调中性粒细胞NETs,减少炎症、氧化应激和细胞凋亡,从而改善肾IRI,从而增强肾功能。
