ABSTRACT
Abstract Chagas disease (CD) is a protozoan zoonosis caused by Trypanosoma cruzi. Reactivation of CD occurs via drug-induced immunosuppression before and during transplantation. Here, we report the case of a 62-year-old man diagnosed with classic Hodgkin lymphoma who received highly aggressive conditioning chemotherapy before undergoing stem cell transplantation (SCT). The patient tested positive for CD in pre-transplantation evaluation. The patient exhibited persistent fever and elevated C-reactive protein levels before and after SCT, and was treated with antibiotics. Micro-Strout test showed evidence of trypomastigotes and he was treated with benznidazole until tested negative. Post-transplantation seropositive patients should be screened for possible reactivation.

Cupriavidus pauculus es un bacilo Gram negativo con metabolismo oxidativo, que se ha aislado de muestras de agua y suelo, pero raramente de personas como entidad clínica. En la literatura científica existen menos de veinte artículos de reportes de caso de este microorganismo. La mayoría han sido pacientes con algún tipo de inmunosupresión, sometidos a procedimientos invasivos, especialmente de tipo vascular, y que han requerido múltiple manejo antibiótico. Cupriavidus pauculus ha mostrado baja virulencia y sensibilidad antibiótica, principalmente a trimetoprim-sulfametoxazol, betalactámicos de amplio espectro y quinolonas. Se presenta el caso de una paciente de 55 años con antecedentes de trasplante renal, que ingresó con infección de tejidos blandos y a quien se le diagnosticó bacteriemia asociada a catéter por C. pauculus durante la hospitalización.
Cupriavidus pauculus it’s a gram-negative bacillus with an oxidative metabolism that has been isolated in water and soil samples, but rarely in people clinical entities. There are less than 20 articles case-reported about this microorganism. Most of which have been patients with some type of immune impairment, mostly subjects with invasive vascular procedures, who had required multiples antibiotic management. Cupriavidus pauculus has mainly shown a low virulence and antibiotic sensibility to trimethoprim-sulfametoxazol, broad spectrum betalactamics and quinolones. As presented in the case of a 55 year old patient with renal transplantation history admitted with a soft tissue infection and diagnosed with a catheter associated bacteremia by C. pauculus, during hospitalization.
