Abstract

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.
