Ralstonia pickettii bacteremia in hemodialysis patients: a report of two cases

Abstract

Ralstonia pickettii is a low-virulence gram-negative bacillus that may be associated with infections related to health care and may cause bacteremia. Ralstonia pickettii bacteremia is uncommon but is related to the contamination of medical products, mainly in immunodepressed patients. We present two cases of patients on chronic hemodialysis with Ralstonia pickettii bacteremia linked to contamination of the dialysis water. Similar cases have been published with links to intravenous fluid administration, medication ampules, and the use of extracorporeal oxygenation membranes, among other factors. The detection of Ralstonia pickettii bacteremia should provoke suspicion and a search for contaminated medical products, fluids, and/or medications.

“…about Ralstonia pickettii , a gram-negative germ formerly of the Burkholderia group that infected two patients on hemodialyisis. (1) The first was a 65-year-old man with a chronic kidney disease and native arteriovenous fistula who, and was managed in the intensive care unit (ICU) because of development of a septic shock. (1) The transesophageal echocardiogram did not show vegetation, but cultures of blood and of dialysis fluid cultures revealed R. pickettii , which was controlled by with meropenem for two weeks.…”
