Treatment of Adenoviral Acute Respiratory Distress Syndrome Using Cidofovir With Extracorporeal Membrane Oxygenation

Area of Science:

• Virology
• Pulmonology
• Critical Care Medicine

Background:

• Adenovirus infections commonly cause respiratory illness in children, but severe lower respiratory infections like pneumonia can occur in specific adult populations.
• Antiviral treatment for adenovirus pneumonia is limited by scarce clinical data and a lack of randomized trials.
• Efficacy of cidofovir in severe adenovirus pneumonia, particularly in the context of acute respiratory distress syndrome (ARDS), is not well-established.

Observation:

• Three adult patients with severe adenovirus pneumonia and ARDS were treated with cidofovir and advanced respiratory support, including extracorporeal membrane oxygenation (ECMO).

Findings:

• All three patients demonstrated a positive clinical response to cidofovir therapy.
• The patients treated with cidofovir and early ECMO support survived the 28-day observation period.
• A literature review identified an additional 15 cases of ARDS associated with adenovirus pneumonia.

Implications:

• Cidofovir, in conjunction with early ECMO, presents a potential therapeutic strategy for managing severe adenoviral pneumonia complicated by ARDS.
• Further research and clinical trials are warranted to confirm the efficacy and optimal use of cidofovir in this critical patient group.
• This study highlights the importance of considering antiviral therapy in immunocompromised adults with severe adenovirus pneumonia and ARDS.
