Drug-induced neurotoxicity is a rare adverse reaction associated with ertapenem. Encephalopathy is a type of neurotoxicity that is defined as a diffuse disease of the brain that alters brain function or structure. We report a patient with normal renal function who developed ertapenem-induced encephalopathy manifesting as altered mental status, hallucinations, and dystonic symptoms. The patient's symptoms improved dramatically following ertapenem discontinuation, consistent with case reports describing ertapenem neurotoxicity in renal dysfunction...

Ventilator-associated pneumonia (VAP) is the most common hospital-acquired infection among mechanically ventilated patients. Our objectives were to determine the incidence of VAP, isolate multidrug-resistant bacteria, identify the most prevalent resistant strains and identify their antibiotic susceptibility pattern. The VAP rate was calculated. The isolated microbes were identified and tested for antibiotic susceptibilities. The minimum inhibitory concentrations were determined of imipenem, meropenem and ertapenem for Klebsiella isolates...

Extended spectrum β-lactamase (ESBL) -producing Enterobacteriaceae are increasing in prevalence worldwide. Carbapenem antibiotics are used as a first line of therapy against ESBL-producing Enterobacteriaceae. We examined gastrointestinal colonization of carbapenem-resistant-ESBLs (CR-ESBL) among a cohort of critical care patients. In this cohort of patients, we cultured for ESBL-producing Klebsiella spp. and Escherichia coli and then performed MIC susceptibility testing for imipenem, doripenem, meropenem, and ertapenem on the patient's first isolate...

BACKGROUND: There is an urgent need for accurate and rapid diagnostic tests to identify carbapenemase producing enterobacteria (CPE). Here, we have evaluated the Carbapenem Inactivation Method (CIM) test to detect CPEs from cultured colonies. METHODS: A total of 256 enterobacterial isolates were used to evaluate the performance of the CIM in comparison to Carba NP test and molecular detection used a reference method. Ninety three well-characterized isolates (including 29 non-CPE and 63 CPEs of worldwide origin) with decreased susceptibility to at least one carbapenem were used to (i) evaluate the efficacy of CIM test and (ii) to compare it to the Carba NP test...

AIM OF STUDY: Spontaneous bacterial peritonitis (SBP) is the most frequent infectious complication of liver cirrhosis with serious consequences. Initially, SBP is always treated with empirical, not targeted, antibiotic therapy. Since a retrospective study performed in our department showed suboptimal effectiveness (only 40 %) of empirical antibiotic therapy in accordance with the EASL guidelines, a decision was made to change the protocol. The aims of this prospective study were to determine: (1) the incidence and characteristics of SBP in real clinical practice - in a liver unit of a tertiary hospital, (2) the effectiveness of new antibiotic therapy selected based on analysis of the spectrum of pathogens and their resistance to antibiotics as identified in a retrospective cohort study on SBP carried out in our department, (3) mortality, and to compare these findings with the literature data...

BACKGROUND: Ertapenem is a broad spectrum carbapenem antibiotic and is being explored against Mycobacterium tuberculosis Carbapenems have anti-bacterial activity when the plasma concentration exceeds the minimal inhibitory concentration at least 40% of the time (40%T>MIC). To assess 40%T>MIC in multidrug-resistant tuberculosis (MDR-TB) patients, a limited sampling strategy was developed using a population pharmacokinetic model based on healthy volunteers. METHODS: A two-compartment population pharmacokinetic model was developed from data in forty-two healthy volunteers, using an iterative two-stage Bayesian method...

The emergence of resistance to multiple antimicrobial agents in pathogenic bacteria is a significant public health threat, as there are limited effective antimicrobial agents for infections caused by multidrug-resistant (MDR) bacteria. Several MDR bacteria are now frequently detected. Carbapenem resistance in Enterobacteriaceae is often plasmid mediated, necessitating stringent infection control practices. Wedescribe an outbreak of carbapenem-resistant Providencia rettgeri involving 4 patients admitted to intensive care and high-care units at a tertiary hospital...

The Clostridium difficile PCR ribotype complex 078/126 (RT078/126) is often involved in human disease and is also frequently isolated from diverse animal species. The high genetic relatedness between human and animal RT078/126 isolates found in different regions has encouraged discussion about the zoonotic potential of this lineage. We compared for the first time the genetic diversity and antimicrobial susceptibility profiles of human and animal C. difficile RT078/126 isolates from Spain. A collection of 96 isolates (50 of human and 46 of animal origin; 63 and 33 of ribotypes 078 and 126, respectively) was subtyped by an improved amplified fragment length polymorphism (AFLP) fingerprinting method and tested for in vitro antimicrobial susceptibility...

The number and type of outer membrane (OM) channels responsible of carbapenem uptake in Acinetobacter are still not well defined. Here, we addressed these questions using Acinetobacter baylyi as a model species and a combination of methodologies aimed to characterize OM channels in their original membrane environment. Kinetic and competition analyses of imipenem (IPM) uptake by A. baylyi whole cells allowed us to identify different carbapenem-specific OM uptake sites. Comparative analyses of IPM uptake by A...
