Background:
Leptospirosis is an infectious disease caused by pathogenic Leptospira spp., which could result in severe illnesses. Indirect contact with these pathogens is more common. Individuals could contract this disease through contact with contaminated water or during floods. In this case, we present the details of a 40-year-old male pig farmer who suffered from severe pulmonary hemorrhagic leptospirosis and multiple organ failure. The diagnosis of leptospirosis was confirmed through metagenomics next-generation sequencing (mNGS) while the patient received extracorporeal membrane oxygenation (ECMO) support, and antibiotic treatment was adjusted accordingly. The patient underwent comprehensive treatment and rehabilitation in the intensive care unit.
Conclusion:
This case illustrates the importance of early diagnosis and treatment of leptospirosis. While obtaining the epidemiological history, second-generation metagenomics sequencing was utilized to confirm the etiology. The prompt initiation of ECMO therapy provided a crucial window of opportunity for addressing the underlying cause. This case report offers valuable insights for diagnosing patients with similar symptoms.
Insights
Early diagnosis and treatment are crucial for severe leptospirosis. Metagenomics next-generation sequencing (mNGS) confirmed the diagnosis in a pig farmer with pulmonary hemorrhage and organ failure, enabling timely extracorporeal membrane oxygenation (ECMO) support.
Area of Science:
- Infectious Diseases
- Genomics
- Critical Care Medicine
Background:
- Leptospirosis, caused by Leptospira spp., is a severe infectious disease often contracted via indirect contact with contaminated environments.
- Pulmonary hemorrhage and multiple organ failure are potential severe manifestations of leptospirosis.
Observation:
- A 40-year-old male pig farmer presented with severe pulmonary hemorrhagic leptospirosis and multiple organ failure.
- The patient required extracorporeal membrane oxygenation (ECMO) support and adjusted antibiotic therapy.
Findings:
- Metagenomics next-generation sequencing (mNGS) confirmed the diagnosis of leptospirosis.
- Prompt initiation of ECMO therapy was critical for patient management.
Implications:
- This case highlights the utility of mNGS in diagnosing severe leptospirosis.
- Early diagnosis and aggressive supportive care, including ECMO, are vital for improving outcomes in severe leptospirosis cases.
