Strongyloidosis Hyperinfection Syndrome in an HIV-Infected Patient: A Rare Manifestation of Immune Reconstitution Inflammatory Syndrome

الملخص EN

Parasitic infections such as Strongyloides stercoralis and HIV have been reported to coexist, particularly in resource-limited settings such as India.

In an immunocompromised host, S.

stercoralis can progress to strongyloidiasis hyperinfection syndrome (SHS).

However, SHS is not common in patients with advanced HIV disease.

Immune reconstitution inflammatory syndrome (IRIS) developing after initiation of antiretroviral therapy (ART) can target multiple pathogens including S.

stercoralis.

The authors present here a 46-year-old HIV-infected female who was recently diagnosed with HIV-1 infection, started ART, and developed SHS.

Her upper GI endoscopy revealed severe gastroduodenitis, and X-ray chest showed extensive bilateral pneumonitis.

We could identify S.

stercoralis in induced sputum and duodenal biopsy.

We could also identify gut inflammation to restrict invading parasites.

After receiving antihelminthic therapy, she showed improvement, a course of events that fit the diagnosis of unmasking S.

stercoralis IRIS.
