Clinical Report: Acute respiratory distress syndrome and severe pneumonia linked to avian influenza A (H10N3)
Background
Avian influenza A viruses, particularly subtypes like H10N3, pose a significant risk for severe respiratory illness in humans, despite their rarity. Human infections are often linked to direct contact with infected poultry. Understanding such cases is crucial for public health and clinical management.
Data Highlights
No numerical or trial data provided in the source material.
Key Findings
A 23-year-old female developed ARDS and severe pneumonia after exposure to avian influenza A (H10N3).
Initial treatment included empirical antimicrobial therapy, which was later adjusted based on clinical progression.
Metagenomic next-generation sequencing identified influenza virus and Candida albicans in bronchoalveolar lavage fluid.
The patient required invasive mechanical ventilation and veno-venous ECMO due to persistent hypoxemia.
Despite negative cultures for common respiratory pathogens, bacterial co-infection was suspected based on elevated procalcitonin levels.
Clinical Implications
Clinicians should consider avian influenza A in patients with severe pneumonia and a relevant exposure history, even when initial diagnostic tests are negative.
Conclusion
This case highlights the potential severity of H10N3 infections and the importance of prompt diagnosis and treatment in patients with suspected avian influenza.
Heart rate monitoring and atrial fibrillation detection had the strongest supporting evidence, but investigators found limited evidence for broader outpatient self-monitoring applications.
