Safety and Efficacy of Vancomycin Plus Beta-lactams

Registration Number
NCT03776409
Lead Sponsor
First Affiliated Hospital Xi'an Jiaotong University
Brief Summary

The combination of vancomycin and piperacillin-tazobactam has been associated with an increased risk of acute kidney injury (AKI) in non-critically ill patient populations, but it is still unknown if this association exists in critically ill patients. The objective of this study is to compare AKI and efficacy of vancomycin plus piperacillin-tazobactam or beta-lactams.

Detailed Description

The combination of vancomycin and piperacillin-tazobactam has been associated with an increased risk of acute kidney injury (AKI) in non-critically ill patient populations, but limited data regarding this association exists in critically ill patients. The objective of this study is to compare AKI and efficacy of vancomycin plus piperacillin-tazobactam or beta-lactams.

This is a multicenter, retrospective cohort study. Patients from the retrospective cohort will be divided into 2 groups based on the combination regimen received . Patients who meet the inclusion and exclusion criteria will be included in our registry. As a non-intervention study, these information as below will be collected: basic demographics, diagnosis, concomitant nephrotoxic and other antibiotic medications, serum creatine levels, vancomycin concentrations, and indication for antibiotics.

vancomycin plus piperacillin/tazobactamvancomycin plus piperacillin/tazobactamCritically ill patients who received the combination of VAN (vancomycin) and PTZ (piperacillin/tazobactam) for at least 48 hours during an ICU (intensive care unit) admission, had a baseline serum creatinine (Scr) concentration value within 24 hours of hospital admission.The dosage and frequency of VAN and PTZ were adjusted based on clinical practice and patient characteristics. This is an observational study without any intervention.
vancomycin plus other beta-lactamsvancomycin plus other beta-lactamsCritically ill patients who received the combination of VAN (vancomycin) and other beta-lactams (cefoperazone/sulbactam, meropenem, imipenem/siastatin, ceftriaxone, ceftazidime, et al) for at least 48 hours during an ICU (intensive care unit) admission, had a baseline serum creatinine (Scr) concentration value within 24 hours of hospital admission.The dosage and frequency of VAN and other beta-lactams were adjusted based on clinical practice and patient characteristics. This is an observational study without any intervention.
Primary Outcome Measures
NameTimeMethod
clinical efficacyfrom 24 hours after the start of the combination until discharge up to one month

microbial eradication

AKI(acute kidney injury)from 24 hours after the start of the combination until discharge up to one month

the incidence of acute kidney injury

Secondary Outcome Measures
NameTimeMethod
onset of AKIthe first occurence of AKI after starting concomitant antimicrobial use up to one month
whether renal function return to baseline or notfrom AKI onset to resolution of defined AKI up to one month

whether defined AKI was resoluted or not

the length of hospital stayfrom hospital admission to discharge up to one month
duration of AKIthe time from AKI onset to resolution of AKI up to one month
major acute kidney events at 30 days (MAKE30)MAKE30 is assessed 30 days following AKI diagnosis

MAKE30 is assessed 30 days following AKI diagnosis, which is a composite outcome of death, new dialysis, and worsened renal function.

vancomycin trough value assessmentfrom hospital admission to discharge up to one month

assess the impact of vancomycin exposures on development of AKI
