简要总结
This study is to investigate the recent epidemiological trends and the treatment outcome in terms of the length of hospital stay, the relevant renal and neurological side effects, risk factors for developing these side effects, the selection of more resistant pathogens under therapy as well as the incidence of Clostridium difficile infections under treatment.
详细描述
Increasing resistance among Enterobacterales to beta-lactam antibiotics is globally a major concern in the antibiotic resistance crisis. In gram-negative bacteria it evolves primarily through the production of beta-lactamases that allow the rapid hydrolysis of common antibiotics - most notably 3rd generation cephalosporins. Particularly, the production of Ambler class C beta-lactamase (AmpC) is a very concerning and unique resistance mechanism as so called derepressed mutants can be induced during treatment. Information on recent epidemiological trends as well as comparative information about the treatment strategies (cefepime versus piperacillin/tazobactam versus carbapenems) for infections with AmpC-producing Enterobacterales in Switzerland is still lacking. This study is to investigate the recent epidemiological trends and the treatment outcome in terms of the length of hospital stay, the relevant renal and neurological side effects, risk factors for developing these side effects, the selection of more resistant pathogens under therapy as well as the incidence of Clostridium difficile infections under treatment.
