Wright C et al. Tricuspid valve infective endocarditis and pulmonary sepsis due to Erysipelothrix rhusiopathiae successfully treated with high doses of ciprofloxacin but complicated by gynaecomastia. Piperacillin/tazobactam-induced acute delirium in a peritoneal dialysis patient Sir, Penicillins are b-lactam antimicrobial agents. They act by binding to penicillin-binding proteins on the bacteri...

Agar dilution sensitivity tests to piperacillin were performed on 497 strains of gram ne­ gative bacilli isolated from blood culture of patients admitted to Maharaj Nakom Chiang Mai Hos­ pital. Piperacillin was found to have significant activity against Pseudomonas aeruginosa, Aero­ monos spp and Enterobacter spp. A substantial proportion of Escherichia coli, Klebsiella pneumo­ niae and Acineto...

OBJECTIVE To determine the in vitro activity of various antimicrobial agents including ertapenem, imipenem, meropenem, fosfomycin, netilmicin, colistin, and piperacillin/tazobactam against clinical isolates of cephalosporin-resistant gram-negative bacteria. MATERIAL AND METHOD All clinical isolates of gram-negative bacteria obtained from patients receiving care at Queen Sirikit National Insti...

Sir, We report here a study that was undertaken to investigate whether ciprofloxacin resistance in Gram-negative noso-comial pathogens is a surrogate marker for cross-resistance to non-fluoroquinolones. The organisms, Escherichia coli (n = 3315), Pseudomonas aeruginosa (n = 1370), Entero-bacter aerogenes (n = 252), Enterobacter cloacae (n = 495), Proteus mirabilis (n = 379), Serratia marcescens...

INTRODUCTION Piperacillin/tazobactam is a commonly used antibiotic for the empirical treatment of severe diabetic foot infections. One of the most feared complications of this drug is the development of pancytopenia. The aim of this study was to determine whether the use of piperacillin/tazobactam caused any hematological changes in patients admitted with severe diabetes-related foot infections...

BACKGROUND A challenge in the empiric treatment of complicated urinary tract infection (cUTI) is identifying the initial appropriate antibiotic therapy (IAAT), which is associated with reduced length of stay and mortality compared with initial inappropriate antibiotic therapy (IIAT). We evaluated the cost-effectiveness of ceftolozane/tazobactam compared with piperacillin/tazobactam (one of the ...

The MICs of imipenem and piperacillin, alone and in combination, against Pseudomonas aeruginosa were determined in a checkerboard titration microdilution assay. A dramatic, one-way antagonism of imipenem for piperacillin was demonstrated in 28 of the 35 strains examined; antagonism was associated with the induction of a beta-lactamase.

UNLABELLED Neutropenia, secondary to immune destruction or maturation arrest, is the most commonly described adverse haematological effect of beta-lactam antibiotics. We describe a case of reversible pancytopenia, with evidence of hypocellular marrow, after a prolonged course of piperacillin/tazobactam for 26 days. KEYWORDS Piperacillin; Tazobactam; Myelosuppression; Neutropenia.

The susceptibility of 128 clinical isolates of Pseudomonas aeruginosa against amikacin, kanamycin, gentamycin, minocycline, colistin, chloramphenicol, claforan , piperacillin and carbenicillin were tested. Piperacillin, carbenicillin, amikacin and claforan are effective against at least 54% of strains tested. The susceptibilities of microorganisms to antibiotics were evaluated in different poin...

The purpose of this study was to compare the efficacy, safety, and cost of piperacillin/tazobactam with cefepime monotherapy in children with febrile neutropenia. A prospective randomized study in children and adolescent with cancer was conducted. Patients were randomly assigned to receive either 80 mg/kg piperacillin/10 mg/kg tazobactam every 6 h (maximum 4.5 g/dose) or cefepime 50 mg/kg every...
