A case of ventricular drainage infection with a rare pathogen in cerebrospinal fluid: vancomycin-resistant Enterococcus faecium.
The purpose of this study was to describe a patient, 7-month-old child with ventriculoperitoneal shunts for hydrocephalus with ventriculitis caused by vancomycin-resistant Enterococcus faecium. Two ventriculoperitoneal shunts were inserted just after birth and on the second month. On the sixth month, both shunts were removed because of dysfunction, and external drainage was inserted. The child developed fever, and lumbar puncture revealed a high leukocyte count and protein concentration after external drainage. Cerebrospinal fluid (CSF) cultures yielded E. faecium, which was resistant to ampicillin, erythromycin, gentamicin, penicillin G, vancomycin, and teicoplanin and was susceptible to chloramphenicol, ciprofloxacin, streptomycin, levofloxacin, and rifampin, as determined by the disk diffusion method. As a result of the antimicrobial susceptibility tests, multidrug antibiotic therapy was changed from vancomycin and ceftazidime to chloramphenicol, rifampin, and meropenem. In addition, a rifampin-clindamycin-impregnated shunt (The Codman Hakim Bactiseal, Raynham, MA) was inserted. The patient became afebrile, and CSF cultures were sterile after 15 days of yielding E. faecium. Implantation of the rifampin-clindamycin-impregnated shunt and timely use of appropriate antibiotics for 10 days according to antimicrobial susceptibility testing seem to be important in the resolution of vancomycin-resistant enterococci infections, especially in countries where linezolid and quinupristin-dalfopristin are not in use yet.
