Immunosuppression with Antitumour Necrosis Factor Therapy Leading to Strongyloides Hyperinfection Syndrome

الملخص EN

Strongyloides stercoralis is an endemic parasitic infection that can remain asymptomatic for years, but it can cause death in immunosuppressed individuals.

Here, we present a case of Strongyloides hyperinfection in a 75-year-old male secondary to sepsis and chronic immunosuppression due to TNF-α inhibitors.

Despite aggressive treatment including broad-spectrum antibiotics and antihelminths, his respiratory failure worsened and he died after palliative extubation.

S.

stercoralis infection remains a diagnostic challenge.

Presentation with Strongyloides is often nonspecific, and eosinophilia is absent in hyperinfection.

Diagnosis can be delayed, especially in low-prevalence areas where suspicion is low.

Strongyloides should be considered in the differential diagnosis in the presence of risk factors including immunosuppressive therapy, and a travel history should be carefully obtained.

Patients with recurrent enterobacterial sepsis or respiratory failure with diffuse infiltrates in the setting of eosinophilia should undergo testing for Strongyloides.

A multidisciplinary approach can result in earlier diagnosis and favorable outcomes.
