Strongyloidiasis in immunosuppressed patients

L H Boram, K F Keller, D E Justus

    American Journal of Clinical Pathology
    |December 1, 1981
    PubMed
    Summary

    Severe strongyloidiasis, a parasitic infection, is increasingly seen in immunosuppressed patients. This study highlights unusual cases in a non-endemic area, emphasizing diagnostic challenges and treatment resistance.

    Area of Science:

    • Medical Parasitology
    • Immunology
    • Infectious Diseases

    Background:

    • Strongyloidiasis is a parasitic nematode infection.
    • Immunosuppressive therapy increases risk of severe strongyloidiasis.
    • Steroid therapy is a common immunosuppressive treatment.

    Observation:

    • Three severe cases of Strongyloides stercoralis infestation occurred in patients on steroid therapy over 26 months.
    • All patients resided in a non-endemic metropolitan area.
    • One patient's stool sample uniquely showed multiple parasite life cycle stages without purgatives or anthelminthics.

    Findings:

    • Steroid therapy is associated with severe strongyloidiasis even in non-endemic urban settings.
    • Diagnosis can be challenging, with a single stool sample potentially revealing diverse parasite stages.
    • Persistent strongyloidiasis can occur despite standard treatment, as seen in a renal transplant patient receiving thiabendazole.

    Implications:

    • Increased vigilance for strongyloidiasis is needed in immunosuppressed patients, regardless of geographic location.
    • Diagnostic methods may require optimization for early detection in at-risk populations.
    • Treatment-resistant strongyloidiasis necessitates further research into alternative therapeutic strategies.
