Hemodialysis Central Venous Catheter-Associated Bloodstream Infection Caused by Stenotrophomonas maltophilia Treated with Cefiderocol and Levofloxacin After Failure of Trimethoprim-Sulfamethoxazole Monotherapy and Device Replacement
Abstract
Background: Stenotrophomonas maltophilia infections represent a clinical challenge in treating frail and immunocompromised patients. Alternatives to trimethoprim-sulfamethoxazole (SXT) are needed, with cefiderocol (FDC) representing a promising option, but clinical evidence is limited; moreover, data to support the superiority of mono or combination therapy are lacking. Case presentation: We describe the case of a 55-year-old female patient with a tunneled hemodialysis central venous catheter (HD-CVC)-associated bloodstream infection caused by S. maltophilia that, after failure of a prolonged SXT monotherapy, was successfully treated by HD-CVC replacement followed by intravenous cefiderocol (FDC) and levofloxacin (LVX). Conclusions: FDC represents an interesting option for complex cases of S. maltophilia bloodstream infections, and the combination with LVX might add benefit in cases associated with biofilm formation on intravascular devices.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
