Reactivation of chronic Chagas’ disease following allogeneic bone marrow transplantation and successful pre‐emptive therapy with benznidazole

Abstract: This report shows the early detection of reactivation of chronic Chagas’ disease (CCd) in a 27‐year‐old man with chronic myelogenous leukemia undergoing allogeneic bone marrow transplantation (ABMT). Pre‐emptive therapy with benznidazole during a period of 7 weeks led to a rapid recovery of the patient, who remains free of parasitemia 2 years after the bone marrow transplantation.
