Daniel F. McAuley: 多年来,ARDS的管理范式已经发生了显著的演变。最初,我们主要关注ARDS的综合征定义,即严重的急性低氧呼吸衰竭伴有肺部浸润,但并非由心脏功能障碍引起。这种标准化定义在支持治疗方面发挥了关键作用,例如肺保护性通气、俯卧位以及在更严重病例中使用高PEEP和ECMO。然而,这种综合征定义也限制了ARDS药物治疗的发展,因为在表象之下,可能存在多种不同的机制通路。因此,下一步是将ARDS的管理从广泛的综合征定义转向更个性化的方法,特别是针对药物治疗。通过识别具有不同结果和治疗反应的亚表型(如高炎症和低炎症),我们可以更好地针对特定患者进行治疗。尽管目前在床旁难以区分这些亚表型,但随着床旁生物标志物检测技术的发展,我们有望能够更准确地识别患者的炎症表型,并据此进行更有效的治疗干预。然而,重要的是,在临床试验中随机分组治疗仍然是取得进展的关键,以确保我们能够安全有效地应用新的治疗方法。 Daniel F. McAuley: 目前,对于所有ARDS患者,肺保护性通气是金标准,目标是每公斤预测体重6毫升的潮气量和低于30的平台压力。对于中重度ARDS患者,俯卧位通气也是一项重要措施。然而,在药物治疗方面,目前还没有令人信服的疗法。神经肌肉阻滞剂可能对呼吸不同步的患者有益,而关于类固醇在ARDS治疗中的作用仍不确定,但正在进行大型试验以寻找答案。尽管如此,我们应该确保提供卓越的标准护理,并利用新的诊断和试验设计来寻找ARDS的新疗法。未来,重症监护的方法将是与综合征无关的,基于患者的表型进行治疗。这意味着,患者入院后,无论其是否被诊断为ARDS或脓毒症,都将根据其炎症表型接受相应的治疗。例如,高炎症患者将接受针对高炎症的治疗,而低炎症患者将接受其他治疗。这种方法有望提高治疗效果,并最终改善ARDS患者的预后。

Shownotes Transcript

In this forward-looking episode of the SCCM Podcast, Daniel F. McAuley, MD, explores how the clinical and research communities are rethinking acute respiratory distress syndrome (ARDS), shifting from a one-size-fits-all model to a focus on identifying and targeting modifiable traits. Building on his Thought Leader Session at the 2024 Critical Care Congress), Dr. McAuley unpacks the major thematic shift toward precision medicine in critical care.

Instead of treating ARDS as a single, homogenous condition, researchers are increasingly identifying biologically distinct subgroups—especially hyper- and hypoinflammatory phenotypes—that may respond differently to therapies. These insights are fueling a new generation of trials that aim to prospectively apply this knowledge to treatment strategies.

Central to this evolution is the Precision medicine Adaptive platform Network Trial in Hypoaemic acutE respiratory failure (PANTHER)), of which Dr. McAuley is a team member. PANTHER is a Bayesian adaptive platform randomized clinical trial studying novel interventions to improve outcomes for patients with acute hypoxemic respiratory failure. Designed to be adaptive and biomarker informed, PANTHER will test therapies such as simvastatin and baricitinib, based on real-time phenotyping of patients with ARDS.

Throughout the episode, Dr. McAuley reflects on how advances in machine learning and biomarker identification are making precision treatment more feasible. He discusses the importance of maintaining evidence-based supportive care, such as lung-protective ventilation and prone positioning, while integrating new targeted therapies. Discover the latest investigations into potential therapeutic agents—including mesenchymal stromal cells, statins, and extracorporeal carbon dioxide removal—as Dr. McAuley aims to translate early findings into tangible improvements in patient outcomes.

This episode offers critical insights into the changing landscape of ARDS research and patient care, as Dr. McAuley articulates a hopeful vision for the future—one in which targeted, individualized treatments can improve outcomes for patients with one of critical care’s most challenging conditions.

Dr. McAuley is a consultant and professor in intensive care medicine in the regional intensive care unit at the Royal Victoria Hospital and Queen’s University of Belfast. He is program director for the  Medical Research Council/National Institute for Health and Care Research (MRC/NIHR) Efficacy and Mechanism Evaluation Program and scientific director for programs in NIHR.   Access Dr. McAuley’s Congress Thought Leader Session, ARDS: From Treating a Syndrome to Identifying Modifiable Traits here).
