Weil syndrome causing autoimmune haemolytic anaemia

Area of Science:

• Infectious Diseases
• Hematology
• Nephrology

Background:

• Weil syndrome is a severe manifestation of leptospirosis, caused by Leptospira interrogans.
• Leptospirosis commonly presents with jaundice, petechial rashes, and organ failure.
• Anemia is a frequent complication, but autoimmune hemolytic anemia (AIHA) is exceptionally rare.

Observation:

• A patient presented with symptoms consistent with Weil syndrome.
• The patient developed AIHA following Leptospira infection.
• The AIHA was diagnosed based on clinical and laboratory findings.

Findings:

• The patient's AIHA was successfully treated with high-dose steroid therapy.
• This suggests a potential autoimmune mechanism triggered by Leptospira infection.
• Steroids demonstrated efficacy in managing this rare complication.

Implications:

• This case highlights a rare but treatable complication of leptospirosis.
• It underscores the importance of considering AIHA in patients with severe leptospirosis and anemia.
• Early diagnosis and steroid treatment may improve outcomes for patients with this rare presentation.
