Summary

Severe community-acquired pneumonia caused by influenza virus (hereafter referred to as severe influenza pneumonia) is a major etiology of community-acquired pneumonia leading to acute respiratory failure and ICU admission. It can rapidly progress to profound hypoxemia, acute respiratory distress syndrome (ARDS), and multiple organ dysfunction, and remains associated with substantial mortality. Although antiviral therapy-typically neuraminidase inhibitors-and well-established organ-support strategies are currently available, outcomes in a subset of critically ill patients remain poor despite antiviral and supportive care alone, with ICU mortality reported to be as high as 20-30%. Therefore, identifying effective adjunctive interventions beyond standard care to further reduce mortality in severe influenza pneumonia is of great clinical importance for improving outcomes in critically ill patients and alleviating the burden on families and society.

However, the use of systemic corticosteroids in influenza-associated community-acquired pneumonia (CAP) has long been highly controversial. Multiple studies have suggested that corticosteroid therapy may increase mortality among patients with H1N1 influenza. During the early phase of the COVID-19 pandemic, treatment strategies drew on this evidence and generally advised caution regarding corticosteroid use; subsequently, randomized controlled trials (RCTs) such as RECOVERY and REMAP-CAP demonstrated that low-dose corticosteroids (e.g., dexamethasone 6 mg/day) reduce mortality in patients with pneumonia requiring oxygen therapy. Recently, the U.S. Centers for Disease Control and Prevention (CDC) has emphasized the urgent need for RCTs evaluating low- to moderate-dose corticosteroids or other immunomodulatory agents to clarify their role in the management of influenza-associated CAP. Collectively, these observations underscore the urgency of pathogen-directed anti-inflammatory strategies for CAP-associated acute respiratory failure.

Accordingly, we plan to conduct an adaptive, randomized, open-label, controlled trial to evaluate the efficacy and safety of adjunctive corticosteroid regimens at different doses, in addition to early standard supportive care (including guideline-concordant antiviral therapy and organ support), for reducing mortality in patients with severe influenza pneumonia.
