Abstract
Abstract
Fogo selvagem (FS) is an autoimmune disease that is endemic in certain regions of Brazil and appears to be precipitated by an environmental factor. Objective: Our purpose was to confirm the occurrence and prevalence of FS in a population of Xavante Indians living in an endemic region of central Brazil. Methods: Clinical, anthropologic, and immunologic studies were carried out in patients and in normal inhabitants of the Pimentel Barbosa Indian Reservation, Mato Grosso, Brazil. Results: FS was identified and confirmed in 10 patients from a patient pool of 295 with various skin diseases. The Xavante settlement has a total population of 746. Anti-desmoglein 1 autoantibodies were detected in all patients with FS and were absent from more than 300 serum samples collected from randomly selected unaffected persons. Conclusion: FS is strongly linked to outdoor activities and is largely restricted to immunogenetically predisposed persons. FS appears to have been endemic in certain regions of South America for several centuries.
