Prevalence of Vancomycin-resistant Enterococci Among Children with End-stage Renal Failure. Mid-European Pediatric Peritoneal Dialysis Study Group

To evaluate the prevalence of colonization with vancomycin-resistant enterococcus (VRE) in end-stage renal failure (ESRF), we screened the intestinal flora from 338 pediatric ESRF patients treated in 13 pediatric nephrology units in mid-Europe. Eighty-one patients were undergoing hemodialysis, 66 were undergoing chronic peritoneal dialysis, and 191 were transplant recipients. A total of 363 enterococcal strains were recovered from 232 patients. Twenty-seven enterococcal strains from 24 patients (7.1%) had reduced susceptibility to vancomycin (minimal inhibitory concentration [MIC], >4 microg/mL). Although two patients (0.6%) carried enterococci with high-level resistance to vancomycin (MIC, >32 microg/mL; i.e., VRE), strains of enterococcus with reduced susceptibility to vancomycin (ERSV) were recovered from the other 22 subjects. Past use of vancomycin (P = .05) and tacrolimus therapy (P = .011) were independent risk factors for ERSV or VRE carriage. Enterococcal infections occurred with a similar frequency among enterococcal carriers and noncarriers; no infections with VRE or ERSV were reported. In conclusion, the prevalence of ERSV carriage and the rate of VRE colonization among mid-European children and adolescents with ESRF currently are moderate and low, respectively.
