Strongyloides stercoralis: an example of unusual finding of larvae in urinary sediment

Strongyloides stercoralis hyperinfection: an unusual cause of gastrointestinal bleeding.

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...

Host-finding behavior of Strongyloides stercoralis infective larvae to sodium cation, human serum, and sweat.

The host-finding behavior of Strongyloides stercoralis infective larvae was examined by in vitro agarose assay method. As human body fluid contains 0.85% (ca 0.15 molar) NaCl, various concentrations of sodium chloride, from 0.5M to 0.01M (7 steps), were examined. Many larvae were attracted at concentrations between 0.5 and 0.05M of sodium chloride. The concentration of 0.05M attracted the most ...

Diagnosis of Strongyloides stercoralis infection.

Strongyloides stercoralis infects 30 million people in 70 countries. Infection usually results in asymptomatic chronic disease of the gut, which can remain undetected for decades. However, in patients receiving long-term corticosteroid therapy, hyperinfection can occur, resulting in high mortality rates (up to 87%). Strongyloidiasis is difficult to diagnose because the parasite load is low and ...

Pulmonary Strongyloides stercoralis infection

The 17-year-old male patient presented with fever, weakness, dyspnea and weight loss. His chest radiography demonstrated diffuse reticulonodular density, and high-resolution lung tomography indicated diffuse micronodules and prevalent ground-glass pattern. The findings were consistent with miliary involvement. The patient underwent examinations for rheumatology, immunology, cytology and infecti...
