Plasmodium infection unmasked by corticosteroid therapy.
In the past four years, we have encountered three patients in whom malaria parasites were found incidentally in their blood when they were receiving corticosteroid therapy. Although there is little direct evidence that corticosteroid therapy can activate human malaria, animal studies have successfully demonstrated the recrudescence effect of immunosuppression on malaria infection.
