BACKGROUND: The appropriate use of broad-spectrum antibiotics, including appropriate de-escalation, is essential to reduce the emergence of antibiotic resistance. In surgical floors antibiotics are prescribed for prophylaxis (mostly, single dose), empirical treatment (started if infection is suspected till bacteria are identified with its sensitivity to antibiotics), or treatment of well-defined infection of previously isolated bacteria with its sensitivity to antibiotics. In this study, we aimed to evaluate the use of broad-spectrum antibiotics based on requests for cultures and de-escalation based on sensitivity results of culture tests at tertiary care hospital...

INTRODUCTION: Therapeutic drug monitoring (TDM) is a useful tool to optimize antibiotic therapy. Increasing interest in alternative dosing strategies of beta-lactam antibiotics, e.g. continuous or prolonged infusion, require a feasible analytical method for quantification of these antimicrobial agents. However, pre-analytical issues including sample handling and stability are to be considered to provide valuable analytical results. METHODS: For the simultaneous determination of piperacillin, meropenem, ceftazidime and flucloxacillin, a high performance liquid chromatography (HPLC) method including protein precipitation was established utilizing ertapenem as internal standard...

In the recent years, residual antibiotics are considered to be emerging environmental pollutants due to their continuous input and persistence into the aquatic ecosystem even at low concentrations. Therefore, these are necessary to develop efficient methods for the wastewater treatment. The present paper describes the efficiency of several types of multi-walled carbon nanotubes (MWCNTs) for the retention of the selected antibiotics (ampicillin, ceftazidime, cefepime, imipenem, piperacillin, tazobactam, tetracycline, erythromycin, ciprofloxacin, norfloxacin, vancomycin, gentamicin, sulfamethoxazole, and thrimetoprim) from aqueous (synthetic) solutions and wastewater samples...

Optimal dosing of β-lactam antibiotics in critically ill patients is a challenge given the unpredictable pharmacokinetic profile of this patient population. Several studies have shown intermittent dosing to often yield inadequate drug concentrations. Continuous dosing is an attractive alternative from a pharmacodynamic point of view. This study evaluated whether, during continuous dosing, piperacillin concentrations reached and maintained a pre-defined target in critically ill patients. Adult patients treated with piperacillin by continuous dosing in the intensive care unit of a university medical centre in The Netherlands were prospectively studied...

Pranita D Tamma, Jesus Rodriguez-Bano
The continued rise in infections caused by extended-spectrum β-lactamase (ESBL)-producing pathogens is recognized globally as one of the most pressing concerns facing the healthcare community. Carbapenems are widely regarded as the antibiotics of choice for the treatment of ESBL-producing infections, even when in vitro activity to other β-lactams has been demonstrated. However, indiscriminant carbapenem use is not without consequence, and carbapenem overuse has contributed to the emergence of carbapenem-resistant Enterobacteriaceae...

After experiencing a high rate of carbapenem-resistant Gram-negative bacilli infections in febrile neutropenic patients, a two-stage intervention was introduced in the haematopoietic stem cell transplantation (HSCT) centre. During the first eight months of 2014, carbapenems remained the first choice for the empirical treatment of febrile neutropenia while the use of piperacillin/tazobactam (TZP) was encouraged in patients with stable clinical condition. When blood cultures were reported as negative and the patient was clinically stable the carbapenem/TZP treatment was stopped regardless of continuous fever and neutrophil count...

INTRODUCTION: Clostridium difficile infection (CDI) is a significant gastrointestinal disease in the developed world and increasingly recognised as a zoonotic infection. In North America and Europe, the PCR ribotype (RT) 078 strain of C. difficile is commonly found in production animals and as a cause of disease in humans although proof of transmission from animals is lacking. This strain is absent in Australian livestock. We report a case of human CDI caused by a strain of C. difficile belonging to known Australian livestock-associated RT 237...
