microbial and antibiotic susceptibility profile among clinical samples of patients with acute leukemia

introduction: preventing and starting early treatment of infections in patients whose immunity system is weak due to malignancies like leukemia can reduce mortality. this study aimed to determine microbial and antibiotic resistance patterns in clinical samples of patients with acute leukemia to start early treatment before the results of clinical tests are known. subjects and methods: in this cross-sectional study, the clinical samples of all patients hospitalized with the diagnosis of acute leukemia were cultured and their antibiogram was evaluated. then, the data were analyzed by spss 18 based on the objectives of the study. results: of a total of 2,366 samples, 18.95% were reported to be positive blood samples, 22.96% were reported to be urine samples and 36% wound samples. e. coli was the most common bacteria isolated from the blood and urine cultures (34% in blood, 32% in urine culture) while staphylococcus aureus was the most common in the wound culture (35%).the highest level of sensitivity in the organisms with positive blood culture was to ciprofloxacin, while in positive urine and wound culture was to imipenem. the highest resistance in blood, urine and wound culture was to cotrimoxazole. conclusion: according to results obtained from this study, it is necessary to conduct appropriate studies on this issue in specific conditions in our country. the findings of this study can be used in clinics for more accurate diagnosis, more effective treatment before the results of clinical tests are known and also for prevention of infection in cancer patients.
