We characterized carbapenem resistance mechanisms among 12 Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (referred to here as KPC K. pneumoniae) clinical isolates and evaluated their effects on the activity of 2- and 3-drug combinations of colistin, doripenem, and ertapenem. All isolates were resistant to ertapenem and doripenem; 75% (9/12) were resistant to colistin. Isolat...
OBJECTIVES Available data on colistin pharmacokinetics in patients undergoing continuous renal replacement therapy (CRRT) are limited. Our aim was to study colistin pharmacokinetics in critically ill patients treated with colistin methane sulphonate for Gram-negative sepsis and undergoing continuous venovenous haemodiafiltration for acute renal failure. PATIENTS AND METHODS Three patients wer...
The pathogenesis of colistin induced nephrotoxicity is poorly understood. Currently there are no effective therapeutic or prophylactic agents available. This study was aimed to determine the mechanism of colistin induced nephrotoxicity and to determine whether P-glycoprotein (P-gp) induction could prevent colistin induced nephrotoxicity. Colistin induced cell toxicity in cultured human proximal...
A 56-year-old woman with systemic lupus erythematosus had bacteremia due to multidrug-resistant Pseudomonas aeruginosa (MDRP). She was initially treated with imipenem-cilastatin, tobramycin, and aztreonam; however, MDRP was still detected intermittently in her plasma. Multidrug-susceptibility tests demonstrated that MDRP was susceptible only to colistin. Therefore, in addition to these antibiot...
The pharmacological interaction of antibiotic combinations tylosin and colistin was studied. For this purpose, an in vitro challenge method used. results were used to calculate their using the graphic representation known as ISOBOLOGRAM. pure salts tartrate sulfate obtained from manufacturer product, Laboratorios Ecozoo SA de CV Mexico. bioassay agar wells quantify results, following criteria u...
Recent clinical studies performed in a large number of patients showed that colistin "forgotten" for several decades revived for the management of infections due to multidrug-resistant (MDR) Gram-negative bacteria (GNB) and had acceptable effectiveness and considerably less toxicity than that reported in older publications. Colistin is a rapidly bactericidal antimicrobial agent that possesses a...
The role of antibiotics in the treatment of Shiga-like toxin (Stx)-producing E. coli infection is still controversial. This study investigated the effects of colistin on Vero cell cytotoxicity caused by the enterohemorrhagic EC O157:H7, and the effects of colistin on Stx and endotoxin release by EC O157:H7. Vero cells were incubated with supernatant collected from EC O157:H7 cultured for 18 h w...
Considerable progress has been made in the last decade towards better understanding of the optimal clinical use of colistin. It has become evident that higher intravenous (iv) colistin methanesulfonate (CMS) doses are important, probably with the addition of a loading dose in critically ill patients. Higher CMS doses lead to increased risk of nephrotoxicity, which seems reversible in most cases...
