Duodenal strongyloidiasis and hyperinfection syndrome: case report and literature review

Strongyloides stercoralis is an intestinal nematode that commonly causes chronic or asymptomatic infection, but in some situations, especially in immunosuppressed patients, infection by this parasite can manifest with extreme severity and high mortality. Hyperinfection syndrome and disseminated strongyloidiasis are two serious, life-threatening presentations associated with immunosuppression. This paper aims to report a case of duodenal strongyloidiasis that was associated with malabsorption syndrome and evolved to hyperinfection.
