Future Directions in Therapies for Acute Respiratory Distress Syndrome

Area of Science:

• Pulmonary Medicine
• Critical Care Medicine
• Translational Research

Background:

• Acute respiratory distress syndrome (ARDS) pathogenesis involves hyperinflammation, endothelial dysfunction, and alveolar epithelial injury.
• Previous targeted treatments for ARDS have failed in unselected patient cohorts.
• Recent advances have identified reliable biological subphenotypes of ARDS.

Purpose of the Study:

• To highlight the need for subphenotype-targeted interventions in ARDS.
• To emphasize the limitations of current pharmacologic treatments in unselected ARDS populations.
• To advocate for the advancement of ARDS treatment through precision medicine approaches.

Main Methods:

• Review of recent literature on ARDS pathogenesis and subphenotyping.
• Analysis of the impact of biological subphenotypes on treatment efficacy.
• Synthesis of evidence supporting targeted intervention strategies.

Main Results:

• Biological subphenotypes of ARDS have been identified within the last decade.
• These subphenotypes reflect distinct underlying biological disease states.
• Unselected patient populations have historically shown poor response to targeted therapies.

Conclusions:

• Subphenotype-targeted intervention studies are essential for future pharmacologic treatment of ARDS.
• Precision medicine approaches are necessary to overcome treatment failures in ARDS.
• Further research into ARDS subphenotypes will guide the development of effective therapies.
