Abstract
Background: Acute kidney injury (AKI) is a common problem in hospitalized and critically ill patients who are treated with broad-spectrum antibiotics. Piperacillin–tazobactam (PTZ) and meropenem are two antibiotics that are frequently used to treat severe infections, but questions have been raised about the potential for nephrotoxicity of PTZ, especially when combined with vancomycin. The objective of this systematic review and meta-analysis was to compare the risk of AKI, mortality and AKI recovery between PTZ-based and meropenem-based regimens.
Methodology: Studies that compared PTZ and meropenem and reported renal outcomes were identified through a systematic search of literature. Eighteen cohort studies were published during 2017-2025 and fulfilled the inclusion criteria and were included in the qualitative and quantitative synthesis. The Newcastle–Ottawa Scale (NOS) was used to evaluate the quality of the studies. Pooled risk ratios (RRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using random-effects models. The I² statistic was used to measure heterogeneity.
Results: 37,678 patients were included in 18 studies who were treated with PTZ and 5,631 patients who were treated with meropenem. Meta-analysis revealed that there was a significantly higher risk of AKI associated with PTZ than meropenem (RR = 1.65, 95% CI: 1.37–2.00, P < 0.0001) and significant heterogeneity between studies (I² = 74.3%). The rates of AKI were 15.0% in the PTZ group and 13.8% in the meropenem group. There was significantly less mortality in patients receiving PTZ compared with those receiving meropenem (RR = 0.77, 95% CI: 0.62–0.95, P = 0.017), with low to moderate heterogeneity (I² = 43.5%). No significant difference was observed in AKI recovery rates between groups (OR = 1.18, 95% CI: 0.50–2.78, P = 0.706).
Conclusions: PTZ was significantly more likely to be associated with an AKI than meropenem but was not associated with higher mortality and similar rates of recovery from AKI. Renal monitoring should be considered during PTZ therapy, especially in high-risk patients, in the context of antimicrobial effectiveness and stewardship issues.

Key words: Piperacillin–Tazobactam, Meropenem, Acute Kidney Injury, Systematic Review and Meta-Analysis
