Urosepsis is defined as a severe disease due to organ failure caused by a urinary tract infection. An empirical antibiotic therapy should be instigated within the first hour after diagnosis. Urine cultures and blood cultures should be performed before antibiotic treatment. Further diagnostics should be carried out at an early stage to enable an interventional focus control in the case of urinary tract obstruction or abscess formation, if necessary. Gram-negative pathogens are most frequently isolated. Extended spectrum beta-lactamase (ESBL) forming bacteria as a cause of urosepsis are increasing...

INTRODUCTION: Piperacillin/tazobactam is a commonly used antibiotic for the empirical treatment of severe diabetic foot infections. One of the most feared complications of this drug is the development of pancytopenia. The aim of this study was to determine whether the use of piperacillin/tazobactam caused any hematological changes in patients admitted with severe diabetes-related foot infections from a specialist multidisciplinary foot clinic. Specifically, looking at whether it caused anemia, leukopenia, neutropenia, or thrombocytopenia...

This study aimed to demonstrate that organic anion transporters (OATs) mediate the drug-drug interaction (DDI) between piperacillin and tazobactam. After co-administration with piperacillin in rats, the AUC of tazobactam in plasma was significantly increased, and t1/2β was prolonged with significant reduction in plasma clearance, renal clearance and cumulative urinary excretion. In rat and human kidney slices, probenecid, p-aminohippurate and benzylpenicillin inhibited the uptake of piperacillin and tazobactam...

Dosing recommendations for continuous infusion of piperacillin, a broad-spectrum beta-lactam antibiotic, are mainly guided by outputs from population pharmacokinetic models constructed with intermittent infusion data. However, the probability of target attainment in patients receiving piperacillin by continuous infusion may be overestimated when drug clearance estimates from population pharmacokinetic models based on intermittent infusion data are used, especially when higher doses (e.g. 16g/24h or more) are simulated...

Multidrug resistant Pseudomonas aeruginosa has frequently been reported as the cause of nosocomial outbreaks of burn wound infections. The pathogenesis of P. aeruginosa is partly due to the production of several cell-associated and extracellular virulence factors. A total of 93 P. aeruginosa isolated from burn wound infections were investigated for antimicrobial susceptibility and distribution of virulence genes. All (100%) isolates were resistant to one or more antimicrobial agents. The most frequent resistance found against ampicillin (91...

Beta-lactam/beta-lactamase inhibitor combinations (BLBLIs) are among the most controversial classes of antibiotic agents available for the treatment of infections caused by extended-spectrum beta-lactamase (ESBL)-producing Gram-negative bacteria (ESBL-GNR). Piperacillin-tazobactam (PTZ) is one of the most frequently utilized antibiotic agents for empiric gram-negative bacterial coverage and remains active against a large proportion of ESBL-GNR. Furthermore, good antimicrobial stewardship practices encourage the use of carbapenem-sparing treatment regimens for infections due to ESBL-GNR...

Relebactam (formerly known as MK-7655) is a non-β-lactam, bicyclic diazabicyclooctane, β-lactamase inhibitor that is structurally related to avibactam, differing by the addition of a piperidine ring to the 2-position carbonyl group. Vaborbactam (formerly known as RPX7009) is a non-β-lactam, cyclic, boronic acid-based, β-lactamase inhibitor. The structure of vaborbactam is unlike any other currently marketed β-lactamase inhibitor. Both inhibitors display activity against Ambler class A [including extended-spectrum β-lactamases (ESBLs), Klebsiella pneumoniae carbapenemases (KPCs)] and class C β-lactamases (AmpC)...
