Strongyloidiasis, a helminth infection caused by Strongyloides stercoralis, can be complicated by hyperinfection, especially in the setting of immunosuppression; however, many patients go undiagnosed. One clue to diagnosis is unexplained gram-negative bacteraemia or meningitis in patients who are immunosuppressed. Serology can be helpful but may be negative in these patients who are immunocompromised.We present the case of a white cisgender man from Central America in his 40s, living with HIV, with a CD4 count of 77 cells/µL. He was diagnosed with Strongyloides hyperinfection after an increase in his steroid dose. He also had Escherichia coli meningitis and bacteraemia. Strongyloidiasis was diagnosed by stool microscopy despite a negative serology test.This case highlights the challenges in diagnosing strongyloidiasis in the setting of immunosuppression. A high index of clinical suspicion is warranted for patients living with HIV on high-dose corticosteroids. Up to three stool microscopy studies for Strongyloides should be sent in addition to serology.
