BACKGROUND Antibiotic homogeneity is thought to drive resistance but in vivo data are lacking. In this study, we determined the impact of antibiotic homogeneity per se, and of cefepime versus antipseudomonal penicillin/β-lactamase inhibitor combinations (APP-β), on the likelihood of infection or colonisation with antibiotic resistant bacteria and/or two commonly resistant nosocomial pathogens (...

We undertook a prospective, randomized open comparison of the broad-spectrum cephalosporins cefepime and ceftazidime in treatment of hospitalized subjects with skin or wound infections and complicated nosocomial urinary tract infections. Cefepime treatment (dosage, 2.0 g intravenously twice daily for 4 to 28 days) was successful in 36 (90%) of 40 infections of the skin and skin structure or wou...

Pharmacokinetics of cefepime was studied after single dose intravenous administration at the dose rate of 5 mg/kg body weight in calves. Blood samples were collected from the jugular vein at predetermined time intervals before and after drug administration. Serum was harvested and analysed for cefepime concentration by reverse-phase high performance liquid chromatography. Following intravenous...

Septicemia is one of the most life threatening problems and a major cause morbidity mortality particularly in neonates children. The current research was carried out on identification antibiotics susceptibility pattern pathogens responsible for septicemia. A total 121 samples were collected from septicemia suspected infants admitted lady Reading Hospital (LRH), Peshawar, Pakistan. Among samples...

BACKGROUND The pharmacodynamic characteristics of antibiotics should be considered when choosing empiric dosage regimens for the treatment of pneumonia. OBJECTIVE This study compared the probabilities of achieving requisite pharmacodynamic exposure (ie, f T > MIC, AUC/MIC) for antibiotics given for the empiric treatment of hospital-acquired pneumonia (HAP) as recommended by the 2005 guideline...

The CLSI reduced the cefepime Enterobacteriaceae susceptibility breakpoint and introduced the susceptible-dose-dependent (S-DD) category. In this study, MICs were determined for a Gram-negative collection to assess the impact of this change. For Enterobacteriaceae, this resulted in <2% reduction in susceptibility, with 1% being S-DD. If applied to Pseudomonas aeruginosa, the % susceptibility (%...

The antibacterial activities of human regimens of cefepime, ceftazidime, and imipenem alone or in combination with amikacin against an isogenic pair of Enterobacter cloacae strains (wild type and its corresponding derepressed cephalosporinase mutant) were compared by using our nonlethal model of pneumonia with 180 immunocompetent rats. Compared with untreated animals, all beta-lactam-treated ra...

Dear Editor, Cefasporins such as cefepime are beta-lactam antibiotics with a broad antimicrobial spectrum. They are commonly used as first-line agents in the treatment of many infections.1 Reversible encephalopathy is a known neurotoxic complication of cefalosporins.2 Previous case reports have documented triphasic waves on electroencephalography (EEG) in cephalosporin-induced encephalopathy.1-...
