Antifungal-lock therapy (AfLT) has arrived as an investigational approach Addams Family for preventing catheter removal with limited clinical evidence of its efficiency.The principle of AfLT consists of catheter lumen replenishment by a selected antimicrobial agent and then locking it for an alternative treatment to eradicate the microbes embedded in endoluminal biofilms.Herein, we report a pediatric hematology-oncology patient with Candida parapsilosis-related central 5-HTP venous access device infection in which catheter removal was performed despite the systemic and intraluminal caspofungin treatment.For now, we recommend higher doses of caspofungin for AfLT especially in Candida parapsilosis-related catheter infections.
