Abstract Strongyloides stercoralis chronic infections are usually asymptomatic and underestimated. We used direct fresh stool examination, Ritchie's method, and agar plate culture for diagnosis in patients with eosinophilia and previous residence in endemic areas. The frequency of strongyloidosis detected among these patients was high: 21 of 42 were positive. Among them, 10 were positive only by agar plate culture. After ivermectin treatment, patients resulted negative for parasitological tests and reduced their eosinophil counts. Half of the submitted patients that were followed 4-12 months after treatment remained negative without eosinophilia, except one who showed an eosinophil ascending curve before reappearance of larvae in stools. The high frequency of strongyloidosis found in this group emphasizes the relevance of including this parasitosis among differential diagnosis in patients with eosinophilia and past risk of S. stercoralis infection to prevent disseminated infections secondary to corticoid therapy.
