Abstract
OBJECTIVE: It has been shown in previous studies that inadequate empirical treatment is associated with mortality in a variety of infections caused by Gram-negative bacteria. In this study, the clinical effect of discordance in empirical treatment was investigated in patients with urinary tract infection (UTI) accompanied by bacteremia. MATERIAL AND METHODS: We retrospectively reviewed the files of adult (>18 years old) patients who were diagnosed with UTI in our clinic between January 2014 and December 2015. Cases in which the same causative microorganism grew in both blood and urine cultures were included in the study. Patients using ceftriaxone and carbapenem as empirical antibiotic therapy (EAT) were compared as two different groups. In cases that the ethiologic agents were extended- spectrum beta lactamase (ESBL)-producing Klebsiella pneumoniae and Escherichia coli isolates, if the microorganism was resistant to initial antibiotic treatment the situation was defined as EAT discordance, and if it was sensitive it was defined as EAT concordance. RESULTS: After the exclusion criteria were applied, 65 of the 266 cases examined were taken into the study. Clinical and laboratory features of cases of ceftriaxone and carbapenem groups were similar. There was no statistically significant difference between the two groups in terms of hospital stay and survival (p>0.05). Of 28 cases of ESBL-producing E. coli and K. pneumoniae, 18 were EAT discordant and 10 were EAT concordant. Clinical and laboratory features of EAT concordant and EAT discordant groups were similar. No statistically significant difference was found between the two groups in terms of hospital stay and survival (p>0.05). CONCLUSION: It was considered that ceftriaxone can still be a viable option in the EAT of UTI, which is accompanied by bacteremia without severe sepsis and septic shock findings. It was concluded that EAT discordance may not have a negative effect on the duration of hospital stay and survival rates in neither total cases nor ESBL positive ones.
