Thirty laboratories evaluated the in-vitro activity of meropenem and 15 commonly used antibiotics against selected microorganisms isolated in 1994-95 from hospitalized patients with serious infections requiring antibacterial treatment. Isolates (2169) from blood, sputum, pus or CSF were included. MICs were determined with Etest and NCCLS breakpoints were used. In general, the MICs of meropenem ...
We evaluated the activities of meropenem, imipenem, temocillin, piperacillin, and ceftazidime by determination of the MICs for 66 genotypically characterized Burkholderia cepacia isolates obtained from the sputum of cystic fibrosis patients. In vitro synergy assays, as performed by the time-kill methodology, of two- and three-drug combinations of the beta-lactams with tobramycin, rifampin, and/...
The pharmacokinetics of meropenem were studied after intravenous infusion in 13 patients grouped according to the impairment of their renal function. Creatinine clearance (CLCR) was greater than 50, 50 to 30, and less than 30 ml/min in groups I, II, and III, respectively. Two other groups, groups IV and V, each comprising four patients with end-stage renal disease (CLCR, < 5 ml/min), were also ...
PURPOSE To investigate antimicrobial combinations for synergy or antagonism against isolates of Staphylococcus aureus and Pseudomonas aeruginosa. METHODS Isolates were collected from cases of microbial keratitis from six centers in the United Kingdom. Minimum inhibitory concentrations (MICs) were determined by using E-test strips for 16 antimicrobials, including both current and potentially a...
Meropenem was compared with imipenem/cilastatin for the treatment of serious bacterial infections in a randomized, prospective multicentre study. Both study drugs were given intravenously 1 g every 8 h and no other antimicrobial agents were permitted concomitantly. Of the 204 patients enrolled, the treatment of 177 was evaluable for clinical efficacy and 115 for bacteriological efficacy. In the...
With the widespread emergence of antimicrobial resistance, combination regimens of ceftriaxone and vancomycin (C+V) or ceftriaxone and rifampin (C+R) are recommended for empirical treatment of pneumococcal meningitis. To evaluate the therapeutic efficacy of meropenem (M), we compared various treatment regimens in a rabbit model of meningitis caused by penicillin-resistant Streptococcus pneumoni...
The aim of this study was to determine the effect of subminimal inhibitory concentrations (subMICs) of ceftazidime, meropenem and gentamicin on the in vitro serum sensitivity of Pseudomonas aeruginosa strains isolated from a variety of isolation sites at two medical wards and an intensive care unit in a government university hospital in Croatia. A total of 20 serum-resistant P aeruginosa strain...
The broad antibacterial spectrum and the low incidence of seizures in meropenem-treated patients qualifies meropenem for therapy of bacterial meningitis. The present study evaluates concentrations in ventricular cerebrospinal fluid (CSF) in the absence of pronounced meningeal inflammation. Patients with occlusive hydrocephalus caused by cerebrovascular diseases, who had undergone external ventr...
Vaborbactam (formerly RPX7009) is a new beta-lactamase inhibitor based on a cyclic boronic acid pharmacophore. The spectrum of beta-lactamase inhibition by vaborbactam and the impact of bacterial efflux and permeability on its activity were determined using a panel of strains with beta-lactamases cloned from various classes and a panel of Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing ...
Use of high ultrafiltrate flow rates with continuous venovenous hemofiltration (CVVHF) in critically ill patients is an emerging setting, for which there are few data to guide drug dosing. The objectives of this study were, firstly, to investigate the pharmacokinetics of meropenem in critically ill patients with severe sepsis who are receiving high-volume CVVHF with high-volume exchanges (> or ...
