Efficacy and safety of cefoperazone-sulbactam and piperacillin-tazobactam in treatment of complicated urinary tract infection
OBJECTIVE To explore the safety and efficacy of cefoperazone-sulbactam and piperacillin-tazobactam in treatment of complicated urinary tract infections(cUTIs).METHODS A total of 213 adult patients with cUTIs who were treated in the First Affiliated Hospital of Air Force Military Medical University from Jan 2019 to Nov 2021 were recruited as the study subjects,103 of whom were treated with cefoperazone-sulbactam,and 110 were treated with piperacillin-tazobactam.The safety and efficacy were judged based on the clinical cure rate,eradica-tion rate of microorganisms,total treatment time of antibiotics,effective treatment time of antibiotics,length of hospital stay,recurrence rate of urinary tract infection,rehospitalization rate and all-cause mortality rate after the antibiotic therapies.RESULTS There were no significant differences in the baseline characteristics between the two groups;the pathogens causing the cUTIs were basically same.In terms of the safety,the recurrence rate of urina-ry tract infection of the piperacillin-tazobactam group was lower than that of the cefoperazone-sulbactam group,while the total duration of antibiotic treatment,effective treatment duration of antibiotic and length of hospital stay were longer in the piperacillin-tazobactam group than in the cefoperazone-sulbactam group(P<0.05).There was no significant difference in the all-cause mortality rate between the two group.In terms of efficacy,the clinical cure rate and eradication rate of microorganisms were higher in the cefoperazone-sulbactam group than in the pip-eracillin-tazobactam group(P<0.05).The incidence of adverse events of the cefoperazone-sulbactam group was higher than that of the piperacillin-tazobactam group(P<0.05).CONCLUSION Cefoperazone-sulbactam and pip-eracillin-tazobactam show high safety and efficacy in treatment of cUTIs induced by ESBL-producing and amin-oglycosides-resistant Enterobacteriaceae.
