Staphylococcus epidermidis arthritis following catheter-induced bacteremia in a neutropenic patient

Abstract

Sepsis due to methicillin-resistant Staphylococcus epidermidis occurred in a neutropenic man during management with a Hickman-Broviac catheter. Despite catheter removal and 10 days of i.v. cefazolin therapy, he developed septic arthritis 6 weeks later in a nonprosthetic hip joint. S. epidermidis was isolated from the joint and found to have plasmid and phage susceptibility patterns identical to the previous blood isolate. This case is the first to document a metastatic infection from catheter-associated S. epidermidis bacteremia. It suggests that cephalosporins may not be optimal in such infections despite in vitro sensitivity. Vancomycin appears to be the drug of choice for S. epidermidis bacteremia in the neutropenic population.
