Nosocomial infections caused by extended-spectrum beta-lactamase (ESBL)-producing gram-negative bacteria complicate therapy and limit treatment options. However, the clinical significance of infections caused by ESBL-producing bacteria remains unclear. A critical examination of the literature provides divergent views of the effect of ESBL carriage on morbidity and mortality and suggests that ES...

BACKGROUND The extensive use of the β-lactam antibiotics in hospitals and in the community has created major resistance problems which has led to increased morbidity, mortality and healthcare costs. The use of the β-lactamase inhibitors in combination with the β-lactam antibiotics is currently the most successful strategy used for circumventing the resistance mechanisms. OBJECTIVE To evaluate...

background the rapid emergence of antibiotic resistance, especially broad-spectrum antibiotics, resulted in the avid use of new potent antibiotics. ceftriaxone and ceftazidime, two third-generation cephalosporin, are usually used to manage complicated and uncomplicated infections. the use of cefepime in resistant infections is increasing gradually, which put this potent antibiotic at risk of re...

Aims : In this study in cirrhosis patients having spontaneous ascites infection (SAI) the investigation of the activity of cefepime being a fourth generation cephalosporin was aimed. Method: 19 patients diagnosed as cirrhosis and having acid infection were taken into the study. Cefepime doses were given to all patients having SAI by adjusting according to the clearance of creatinine, in interva...

This research report assessed the differences in resistance rates and antimicrobial usage-versus-susceptibility relationships of Pseudomonas aeruginosa found in various hospital patient care areas. A simplified case control study was also performed to identify patient-specific risk factors associated with cefepime-resistant P. aeruginosa isolates. Last, we determined the consequence of combinin...

OBJECTIVES Previous data from our research had shown that the novel ceragenin, CSA-13, demonstrated concentration-dependent bactericidal activity against glycopeptide-resistant Staphylococcus aureus. However, it is unknown whether CSA-13 demonstrates a similar property against Pseudomonas aeruginosa. We evaluated CSA-13 antipseudomonal activity compared with cefepime, meropenem, piperacillin/ta...

Objectives: Cefepime/tazobactam is a new ß-lactam/ß-lactamase inhibitor combination licensed for clinical use by Drugs Controller General of India. Aim of our study was to analyze the clinical efficacy and safety of cefepime/tazobactam in patients with sepsis. To the best of our knowledge, this is the first published clinical study on this drug. Materials and methods: A retrospective observatio...

We evaluated the impact of revised Clinical and Laboratory Standards Institute (CLSI) breakpoints for broad-spectrum cephalosporins (BSCs) on the susceptibilities of 1,742 isolates of Enterobacter species, Serratia marcescens, Citrobacter freundii, and Morganella morganii. The 2011 CLSI criteria for cefotaxime and ceftazidime reduced the rates of susceptibility by 2.9% and 5.9%, respectively. T...

INTRODUCTION Combination antibiotic therapy for ventilator associated pneumonia (VAP) is often used to broaden the spectrum of activity of empirical treatment. The relevance of such synergy is commonly supposed but poorly supported. The aim of the present study was to compare the clinical outcome and the course of biological variables in patients treated for a VAP, using a monotherapy with a be...
