Meta Analysis Comparative Study
Is the Combination of Piperacillin-Tazobactam and Vancomycin Associated with Development of Acute Kidney Injury? A Meta-analysis.
To evaluate the association of the development of acute kidney injury (AKI) when piperacillin-tazobactam is used in combination with vancomycin compared with vancomycin with or without a β-lactam. ⋯ Vancomycin + piperacillin-tazobactam was associated with an increased risk of AKI compared with vancomycin ± β-lactam. Practitioners need to be vigilant about this association when prescribing this combination of antibiotics.

High-dose continuous venovenous hemofiltration (CVVH) is a continuous renal replacement therapy (CRRT) used frequently in patients with burns. However, antibiotic dosing is based on inference from studies assessing substantially different methods of CRRT. To address this knowledge gap for imipenem/cilastatin (I/C), we evaluated the systemic and extracorporeal clearances (CLs) of I/C in patients with burns undergoing high-dose CVVH. ⋯ Efficient removal of I/C by high-dose CVVH, a high overall clearance, and a high volume of distribution in burn intensive care unit patients undergoing this CRRT method warrant aggressive dosing to treat serious infections effectively depending on the infection site and/or pathogen.
