Bachground and Objectives: vancomycin resistant Enterococcus (VRE) in immune deficient patient is a significant factor for increase in morbidity and mortality. The aim of this study was to determine VRE carriage rate , its molecular epidemiology and to identify risk factors for acquisition of VRE in children with Acute lymphoblastic leukemia (ALL) in 2007-2008.
Material &Methods: In a cross-sectional study, stool samples of children with ALL in Aliasghar and Mahak hospitals were randomly analyzed for detection of VRE . Enterococci were identified by conventional bacteriologic methods and vancomycin resistance was detected by disk diffusion method and E-test. MIC of vancomycin wase determined by macrodilution method. VanA and VanB genes characterization was performed by a multiplex polymerase chain reaction (PCR), which also confirmed the identification. Questionnaires of patient was done to determine risk factors. Data were analyzed by STT , Mann whithney new , Chi-sqare , Fisher exact , Anova and Kruskal-Wallis tests.
Results: In the present study, of 130 child with ALL admitted to our hematology/oncology an infection units, 33(34.7%) of the 130 patient were colonized with VRE(25.3% of total cases) and remainder of patients were colonized with vancomycin-sensitive strains (VSE), serving as controls. 26 isolates(78.8%) of VRE detected with VanA phenotype and seven isolates(21.2%) with VanB phenotype. In the univariate analysis history of ICU admission(P=0.03)was significantly associated with Enterococcus colonization and had a trend with VRE colonization. age (P=0,007)was significantly associated with VRE phenotype .There was no significant relationship between gender, duration of disease ,number of admission , another disease, history of severe neutropenia among one month ago and history of antibiotic use in three month ago and VRE colonization.
Conclusion: VRE prevalence is high in children with ALL in Iran ,indicating a prompt intervention strategy in the control of VRE particularly in PICU.
