متن کاملUse of β-Lactam/β-Lactamase Inhibitors for Extended-Spectrum-β-Lactamase Infections: Defining the Right Patient Population.
In a multicenter, multinational observational study that included neutropenic patients with bloodstream infections by extended-spectrum-β-lactamase-producing species, Gudiol et al. (Antimicrob. Agents Chemother. 61:e00164-17, 2017, https://doi.org/10.1128/AAC.00164-17) demonstrated that β-lactam/β-lactamase inhibitors are effective treatment options. A review of this work, however, reminds us t...
متن کاملComparative Analysis and Identification of Novel Β-lactamase Inhibitors
β-lactam antibiotics are a broad class of antibiotics, consisting of all antibiotic agents that contain a β-lactam nucleus in its molecular structure. Till now β-lactams like penicillins, cephalosporins, monobactams, and carbapenems have been developed. Resistance to various β-lactam antibiotics among target pathogens were started with its first use.The most widespread and important cause is th...
متن کاملOverview Metallo-β-lactamase inhibitors: Promise for the future?
Carbapenem resistance continues to erode the effectiveness of antibiotics such as imipenem and meropenem in the clinic. Resistance mechanisms can include interplay between porin loss (membrane permeability), mutation of penicillin binding proteins necessary for cell division, and expression of class A, B and D β-lactamases. Bacterial resistance to β-lactams such as penicillin or amoxicillin has...
متن کاملRisk Factors for Resistance to β-Lactam/β-Lactamase Inhibitors and Ertapenem in Bacteroides Bacteremia.
The objective of this study was to determine risk factors for the development of resistance to β-lactams/β-lactamase inhibitors (βL/βLIs) and ertapenem among Bacteroides species bacteremia. We conducted a retrospective case-control study of 101 adult patients with Bacteroides species bacteremia at a 1,051-bed tertiary care medical center. The duration of exposure to βL/βLIs (odds ratio [OR], 1....
