Vancomycin is not nephrotoxic by itself but many patients using it with other nephrotoxic agents show nephrotoxicity to some extent. Whether to monitor or not to monitor vancomycin needs further study. The aim of the present study was to investigate the significance of monitoring vancomycin serum levels in pediatric patients treated from different malignancies. 150 newly diagnosed pediatric patients, with various types of malignancy treated with different nephrotoxic agents including vancomycin, were recruited in the study. All patients had normal renal functions at the start of the study and were divided into three groups; Group I included 50 (21 females) patients received vancomycin without monitoring (VWOM group); Group II included 50 (19 females) patients received vancomycin with monitoring (VWM group); Group III (Control group) included 50 (23 females) patients received vancomycin-free antimicrobial agents (VF group). Vancomycin trough level was determined only for VWM group. The effectiveness of monitoring was estimated by the ability to achieve more rapid response, decrease hospital stay and nephrotoxicity and its effect on total dose of vancomycin. There was a significant decrease in nephrotoxicity in VWM and VF groups, 9 subjects (18%), compared to 15 subjects (30%) in VWOM group (p=0.016). The time needed to show a response achievement was significantly decreased in VWM group compared to VWOM group with mean (SD) of 6.5 (2.5) and 8.7 (3.6) days, respectively (p=0.015). That led to shorter hospital stay in VWM group compared to VWOM group with mean (SD) of 10.1 (3.4) and 12.4 (4.2) days, respectively (p=0.003). Monitoring vancomycin level was important in the examined high risk groups of pediatric cancer patients studied. [Med-Science 2018; 7(1.000): 54-57]
