Summary

Strongyloides stercoralis hyper-infection can be fatal in immunosuppressed patients, even years after exposure. Early recognition and aggressive treatment, including high-dose ivermectin, are crucial for survival, as seen in a unique case with suspected myocarditis.

Area of Science:

  • Infectious Diseases
  • Parasitology
  • Critical Care Medicine

Background:

  • Strongyloides stercoralis poses a severe risk to immunosuppressed individuals, potentially causing life-threatening hyper-infection syndrome.
  • Immunosuppressive therapies, including corticosteroids and cyclophosphamide, increase susceptibility to Strongyloides stercoralis.
  • Prior exposure to Strongyloides stercoralis, even decades ago, can lead to hyper-infection under immunosuppression.

Observation:

  • A case of Strongyloides stercoralis hyper-infection was observed in an 18-year-old female with lupus nephritis undergoing immunosuppressive therapy.
  • The patient presented with severe illness, requiring intensive care and management for multi-organ failure.
  • This case is notable for suspected myocarditis, a rare complication of Strongyloides hyper-infection.

Findings:

  • Delayed eosinophilia was a feature in this patient, highlighting its potential as a diagnostic clue.
  • Aggressive treatment with high-dose ivermectin and granulocyte-colony stimulating factor was critical for patient survival.
  • The case represents the first reported instance of Strongyloides stercoralis hyper-infection associated with suspected myocarditis.

Implications:

  • Highlights the importance of considering Strongyloides hyper-infection in any immunosuppressed patient with a history of exposure, regardless of time elapsed.
  • Underscores the need for prompt and intensive management strategies, including novel therapeutic approaches.
  • Emphasizes the potential for severe and unusual complications, such as myocarditis, in Strongyloides stercoralis hyper-infection.
