Leptospirosis pulmonary haemorrhage: a diagnostic challenge

Area of Science:

• Infectious Diseases
• Pulmonology
• Zoonotic Diseases

Background:

• Leptospirosis is a widespread zoonotic disease with available antibiotic treatments.
• Diagnosis is often delayed due to non-specific symptoms and diagnostic challenges.
• Leptospirosis pulmonary hemorrhage is an increasingly recognized severe manifestation.

Observation:

• Two cases of leptospirosis with pulmonary hemorrhage are presented.
• Both patients experienced rapid deterioration requiring intensive care unit support.
• Massive hemoptysis was a critical complication in these cases.

Findings:

• Leptospirosis pulmonary hemorrhage can occur without classical Weil's disease signs.
• Severe respiratory compromise and bleeding necessitate urgent medical intervention.
• This complication poses a significant threat to patient survival.

Implications:

• Highlights the importance of considering leptospirosis in patients with unexplained pulmonary hemorrhage.
• Emphasizes the need for prompt diagnosis and aggressive management in severe cases.
• Underscores that leptospirosis is a global health concern, not limited to tropical areas.
