Antibiotic-resistant gram-negative bacterial infections in patients with cancer

Clin Infect Dis. 2014 Nov 15;59 Suppl 5(Suppl 5):S335-9. doi: 10.1093/cid/ciu612.

Abstract

Patients with cancer are at high risk for infections caused by antibiotic resistant gram-negative bacteria. In this review, we summarize trends among the major pathogens and clinical syndromes associated with antibiotic resistant gram-negative bacterial infection in patients with malignancy, with special attention to carbapenem and expanded-spectrum β-lactam resistance in Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia--all major threats to our cancer patients. Optimal therapy for these antibiotic-resistant pathogens still remains to be determined.

Keywords: Acinetobacter baumannii; Pseudomonas aeruginosa; carbapenem-resistant Enterobacteriaceae; infections; neutropenia.
