Abstract:
Legionella pneumophila infection is a recognized but rare cause of rhabdomyolysis. While the mechanism of rhabdomyolysis associated with Legionella is unknown, theories include direct invasion of Legionella into the muscle itself, or the release of its endotoxin into the circulation with subsequent muscle injury. In this case report, we describe a case of Legionella pneumonia presenting as altered mental status, high fever, and rhabdomyolysis with acute renal failure. We review the epidemiology, clinical and laboratory findings, and treatment of the disease.
Insights
Legionella pneumophila infection can rarely cause rhabdomyolysis. This case highlights Legionella pneumonia presenting with altered mental status, fever, rhabdomyolysis, and acute kidney injury.
Area of Science:
- Infectious Diseases
- Nephrology
- Neurology
Background:
- Legionella pneumophila is a known, albeit uncommon, cause of rhabdomyolysis.
- The exact mechanism linking Legionella infection to muscle breakdown remains unclear, with hypotheses including direct bacterial invasion or endotoxin-induced injury.
Observation:
- This report details a patient with Legionella pneumonia exhibiting altered mental status, high fever, and severe rhabdomyolysis.
- The patient also developed acute renal failure secondary to the muscle breakdown.
Findings:
- The case underscores the potential for Legionella to manifest with severe systemic complications beyond typical pneumonia.
- Rhabdomyolysis and subsequent acute kidney injury can be presenting features of Legionella infection.
Implications:
- Clinicians should consider Legionella infection in patients presenting with unexplained rhabdomyolysis, especially with concurrent fever and neurological changes.
- Early recognition and treatment of Legionella are crucial to prevent severe complications like acute kidney injury.
