[Malignant strongyloidiasis and the HTLV-I virus].

A significant association between Strongyloides stercoralis and HTLV-1 infections has been demonstrated in areas (such as southern Japan and the Caribbean) where HTLV-1 is endemic. Due to the immunomodulating effects of the virus and the parasite, patients with both infections would be at risk for overwhelming strongyloidiasis as well as for T-lymphocyte haemopathy. S. stercoralis is thought to be a cofactor for viral replication and leukaemogenic power.
