BACKGROUND extended spectrum β-lactamase (ESBL) producing gram negative bacilli are becoming a growing problem worldwide with difficulties in designing a national formulary for empirical treatment of gram negative sepsis. OBJECTIVES In this study, we investigated the in vitro activity of Carbapenems, Pipracillin-Tazobactam, Ciprofloxacin alone or in combination with aminoglycosides against ES...
BACKGROUND DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome is characterized by fever, rash, eosinophilia, and multiorgan failure. Previous reports have described differences in clinical and laboratory findings of DRESS syndrome depending on the inducing drug. Piperacillin has been reported as the drug responsible for this syndrome in 3 patients. OBJECTIVE To analyze and...
We have previously observed a significant reduction of ceftriaxone resistance in Proteus mirabilis associated with an increase in the use of cefepime, along with a decrease in the consumption of broad-spectrum cephalosporins (CEP). However, we did not observe such a reduction with Klebsiella pneumoniae. Therefore, we sought to determine whether replacement of CEP by piperacillin-tazobactam migh...
The purpose of this investigation was to identify newer antimicrobial agents that may be useful in the therapy of melioidosis. The in vitro susceptibilities of 199 clinical isolates of Pseudomonas pseudomallei to 22 antibiotics were determined by standard disk diffusion, and those to 13 antibiotics were determined by agar dilution. Over 90% of the isolates were susceptible to imipenem, piperaci...
Since antimicrobial resistance among uropathogens against current first line agents has affected the management of severe urinary tract infection, we determined the likelihood that antibiotic regimens achieve bactericidal pharmacodynamic exposures using Monte Carlo simulation for five antimicrobials (ciprofloxacin, ceftriaxone, piperacillin/tazobactam, ertapenem, and meropenem) commonly prescri...
OBJECTIVES Pharmacokinetic (PK)/pharmacodynamic (PD) models have become increasingly important in optimizing antimicrobial therapy. This approach is highly recommended by regulatory authorities intending to force the evaluation of antimicrobial action at the site of infection. METHODS Clinical isolates of Pseudomonas aeruginosa and Staphylococcus aureus with MICs of 4, 8 and 16 mg/L for piper...
We sought to study whether the better pharmacokinetic and pharmacodynamic (PK/PD) properties of carbapenems and piperacillin/tazobactam, when the duration of infusion is longer, were associated with lower mortality. PubMed and Scopus were searched for studies reporting on patients treated with extended (≥3 hours) or continuous (24 hours) versus short-term duration (20-60 minutes) infusions of c...
OBJECTIVE To describe a patient who developed acute interstitial nephritis, hepatitis and serum sickness-like syndrome after receiving piperacillin-tazobactam (zosyn) therapy. CASE SUMMARY A 30-year-old woman received a 7-day course of piperacillin-tazobactam as empiric treatment for pneumonia. The patient's kidney function worsened and she turned anuric needing dialysis. She also developed f...
Certain antibiotics, particularly piperacillin, have been reported to be associated with a high incidence of allergic reactions in patients with cystic fibrosis. We initiated a study to determine the relative frequency of allergic reactions, ie, drug-induced fever and rash, to parenteral beta-lactam antibiotics in adult patients with cystic fibrosis. Charts of 111 patients were reviewed for eac...
PURPOSE Combination antibiotic treatment is preferred in nosocomial infections caused by Pseudomonas aeruginosa (P. aeruginosa). In vitro synergism tests were used to choose the combinations which might be used in clinic. The aim of this study was to investigate the synergistic efficacy of synergistic antibiotic combinations in multidrug resistant P. aeruginosa strains. MATERIALS AND METHODS ...
