Resumen

OLARTE-LUIS, Tatiana; CACERES-GALINDEZ, Dolli  y  CORTES, Jorge Alberto. New cephalosporins. Rev. chil. infectol. [online]. 2018, vol.35, n.5, pp.465-475. ISSN 0716-1018.  http://dx.doi.org/10.4067/s0716-10182018000500465.

Bacterial resistance has increased in Latin America and the world, making research and creation of new antimicrobials capable of eradicating resistant microorganisms essential. A review of new cephalosporins and their combinations with a beta-lactamase inhibitor was conducted, collecting data on the spectrum, pharmacokinetic and pharmacodynamic profile and clinical studies of the current indications for ceftaroline, and the combinations ceftazidime with avibactam and ceftolozane with tazobactam. The first one has activity against methicillin-resistant Staphylococcus aureus and coagulase negative Staphylococcus (SCoN) and against penicillin-resistant Streptococcus pneumoniae, therefore approved for use in community-acquired pneumonia and acute bacterial skin and skin structure infections. Among the new combinations, ceftazidime, a third generation cephalosporin with antipseudomonal activity, associated with avibactam, a betalactamase inhibitor, has been shown to be effective in the treatment of abdominal infections and complicated urinary infections. Finally, the combination of ceftolozane with tazobactam has comparable action to ceftazidime with avibactam due to its activity against Gram negative rods, and in combination with metronidazole they do not present inferiority to meropenem in intra-abdominal infections. The clinical studies are presented, as well as the potential indications and clinical scenarios for their use of this cephalosporins.
