Strongyloides stercoralis can affect humans in the form of asymptomatic infections, Strongyloidal hyperinfection syndrome and disseminated Strongyloidiasis depending on the immune response of the host. We report a case of strongyloidial hyperinfection syndrome that subsequently tested positive for HTLV infection.

Strongyloides stercoralis hyperinfection causes high mortality rates in humans, and, while hyperinfection can be induced by immunosuppressive glucocorticoids, the pathogenesis remains unknown. Since immunocompetent mice are resistant to infection with S. stercoralis, we hypothesized that NSG mice, which have a reduced innate immune response and lack adaptive immunity, would be susceptible to th...

Strongyloidiasis, caused by Strongyloides stercoralis, consists of various clinical syndromes. Strongyloidiasis hyperinfection leads to morbidity and mortality particularly in immunocompromized patients. This study aimed to determine the risk factors for strongyloidiasis hyperinfection and clinical outcomes. The medical records for hospitalized patients infected with S. stercoralis at Ramathibo...

Strongyloides stercoralis hyperinfection syndrome due to the acceleration of the autoinfective cycle of the nematode is a life-threatening form of the infection occurring in immunocompromised hosts. Intestinal ileus, which is commonly encountered in this form, may reduce the bioavailability and thus the efficacy of oral anthelminthic drugs used in the treatment of the S. stercoralis hyperinfect...

Strongyloides stercoralis is an endemic nematode to tropical and subtropical regions of the globe. The parasite is capable of autoinfection, which is limited by an intact immune response. In immunocompromised hosts, hyperinfection and dissemination can occur and have a high index of mortality. A hyperinfection syndrome with dissemination is frequently associated with corticosteroid administrati...

Strongyloides is endemic in parts of the United States. Most often it is asymptomatic but it has a wide range of clinical presentations. Because of the unusual capacity of strongyloides for autoinfection, it can cause hyperinfection, when it effects the pulmonary and gastrointestinal systems, or disseminated infection, when other organs are involved. Both hyperinfection and disseminated strongy...

Strongyloides stercoralis is present worldwide and can cause hyperinfection in patients on long-term immunosuppressive doses of steroids, as is sometimes the case for patients treated for leprosy reactions. Strongyloides hyperinfection can present with ileus, as is discussed in this case report. Physicians, including surgeons, should be aware of this entity in order to avoid an unnecessary lapa...

Strongyloidiasis is a parasitic disease that may progress to a disseminated form, called hyperinfection syndrome, in patients with immunosuppression. The hyperinfection syndrome is caused by the wide multiplication and migration of infective larvae, with characteristic gastrointestinal and/or pulmonary involvement. This disease may pose a diagnostic challenge, as it presents with nonspecific fi...

Strongyloides stercoralis is an intestinal nematode of humans that infects tens of millions of people worldwide. S. stercoralis is unique among intestinal nematodes in its ability to complete its life cycle within the host through an asexual autoinfective cycle, allowing the infection to persist in the host indefinitely. Under some conditions associated with immunocompromise, this autoinfective...

We report strongyloides hyperinfection in two patients with generalized hypogammaglobulinemia from multiple myeloma and nephrotic syndrome, despite a significant strongyloides-specific immunoglobulin G (IgG) response. In contrast to reports on animals, where human IgG was shown to be a protective antibody, our observation suggests that in humans, immunity to the infective-stage larvae is not pr...
