Abstract
In patients receiving immunosuppressive therapies, Strongyloides stercoralis can cause a life-threatening septic shock, with multi-organ failure and infestation. Strongyloides hyper-infection should be considered in any immunosuppressed patient who has been exposed to the parasite, even if it is many years since that exposure occurred. Delayed eosinophilia may be a feature and treatment with high doses of anthelmintics may be required. An interesting case of S. stercoralis hyper-infection was recently observed at the Royal Darwin Hospital in tropical, northern Australia. The patient was an 18-year-old female with lupus glomerulonephritis, who was receiving immunosuppression in the form of corticosteroids and pulse cyclophosphamide. The characteristics and intensive-care management of this case, including the use of granulocyte-colony stimulating factor and high-dose ivermectin, are described. The patient, who survived, appears to represent the first reported case of S. stercoralis hyper-infection with suspected myocarditis.
