Hyperinfection syndrome should be considered a potential medical emergency. Thus, treatment should be started immediately if this is being considered. Strongyloides stercoralis Hyperinfection remain quiescent indefinitely, immunosuppression can lead to the hyperinfection syndrome, which is. Whereas in chronic strongyloidiasis and in hyperinfection syndrome the larvae are limited to the GI tract and the lungs, in disseminated.

A report of 3 cases and review of the literature. The larvae mature into adult worms, mate and release eggs in the gastrointestinal tract.

The patient continued to be in severe hypoxic and respiratory failure without improvement. The spectrum of GI strongyloidiasis: He had lived in North East Tennessee for almost 30 yrs.

Immunosuppression is used for preconditioning see above and then to prevent rejection; lifelong immunosuppression is needed. He was discharged home on D83 on valganciclovir, cotrimoxazole, and prednisolone. A follow-up blood culture was negative.

These worms reproduce sexually and produce rhabditiform larvae in turn, which then molt into filariform larvae. Development of a high performance liquid chromatography method with fluorescence detection for the routine quantification of tamoxifen, endoxifen, and 4-hydroxytamoxifen in plasma from breast cancer patients. Physicians should be aware of the endemic areas for strongyloidiasis because of difficulty in diagnosis and high potential for fatal complications [ 2 ].

Owing to increased risk of developing disseminated disease or hyperinfection syndrome, early detection and treatment of strongyloidiasis are extremely important.

Intestinal strongyloidiasis and hyperinfection syndrome

Strongyloides stercolaris infection mimicking a malignant tumour in a non-immunocompromised hyperinfectio. Nevertheless, repeated sputum analysis and BAL specimen were negative for parasites. A unique complication of transplants is the development of graft-versus-host disease GVHD.

Parasitological and immunological diagnoses of strongyloidiasis in immunocompromised and non-immunocompromised children at Uberlandia, State of Minas Gerais, Brazil. Autoinfection is the one of the important characteristic features of the life cycle of Strongyloides stercoralis.

Fatal Strongyloides stercoralis infection in a young woman with lupus glomerulonephritis. Males, people of white race, residents of chronic care institutions [ 9 ], and people working with soil such as persons employed in coal mines and farms are at the greatest risk of acquiring this disease [ 10 ].

It is proposed that larvae carry colonic bacteria during their migration hyperknfection the venous system leading to translocation into the blood and other tissues including the meninges. Immunoglobulins hyprinfection shown to play an important role in the defense against strongyloidiasis. Also stressed the need for both stool and serology assays, as serologies hyyperinfection a higher false-negative rate in this at-risk population.


Due to the asymptomatic nature of intestinal strongyloidiasis, and the risk for hyperinfection, screening of the population in endemic areas especially before considering immunosuppressive therapy is important. Interleukin 4 is important in protective immunity to a gastrointestinal nematode infection in mice.

Most of them are found to have strongyloidiasis after a laboratory work up reveals an incidental finding of eosinophilia. Human immunoglobulin G mediates protective immunity and identifies protective antigens against larval Strongyloides stercoralis in mice.
