RT Journal Article T1 CON: Carbapenems are NOT necessary for all infections caused by ceftriaxone-resistant Enterobacterales A1 Rodriguez-Bano, Jesus A1 Gutierrez-Gutierrez, Belen A1 Pascual, Alvaro K1 Blood-stream infections K1 Escherichia-coli K1 Piperacillin-tazobactam K1 Klebsiella-pneumoniae K1 Efficacy K1 Antibiotics K1 Safety AB Carbapenems are considered the drugs of choice for the treatment of serious infections caused by ceftriaxoneresistant Enterobacterales. However, because of the dramatic increase in carbapenem-resistant organisms worldwide, finding alternatives to carbapenems is a must. The potential options include beta-lactam/beta-lactamase inhibitor combinations, temocillin, cephamycins and some non-beta-lactamdrugs. The most controversial is piperacillin/tazobactam; the results of the MERINO trial are challenged because the isolates of patients with worse outcomes were frequently not susceptible to piperacillin/tazobactam when studied by reference methods, and also because the drug was not administered in extended infusion. Other potential options are briefly discussed. We conclude that carbapenems are not necessary for all patients with infections caused by ceftriaxone-resistant Enterobacterales.
