Targeting Gut–Lung Crosstalk in Acute Respiratory Distress Syndrome: Exploring the Therapeutic Potential of Fecal Microbiota Transplantation

Year: 2025

Type: article

Abstract: The gastrointestinal (GI) tract contributes significantly to the pathogenesis of acute respiratory distress syndrome (ARDS) by influencing systemic inflammation and sepsis, which are key factors in the development of multiple organ dysfunction syndrome (MODS), while the significant impact of gut microbiota in critically ill patients, including those with sepsis and ARDS, further underscores its importance. The intestinal microbiota is vital to immune system function, responsible for triggering around 80% of immune responses. Therefore, it may be hypothesized that modifying fecal microbiota, such as through fecal microbiota transplantation (FMT), could serve as a valuable therapeutic approach for managing inflammatory diseases like lung injury (LI)/ARDS. Indeed, emerging experimental research suggests that FMT may have beneficial effects in ARDS models by improving inflammation, oxidative stress, LI, and oxygenation. However, well-designed randomized clinical trials in patients with ARDS are still lacking. Our study seeks to examine how therapeutic interventions such as FMT might benefit LI/ARDS patients by exploring the interactions between the gut and lungs in this context.
