Antimicrobial Therapy for Infections Caused by Carbapenem-Resistant Gram-Negative Bacteria

Carbapenem-resistance emerging in Gram-negative pathogens, such as Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii, has become a major human health problem globally. The therapeutic options available for carbapenem- resistant pathogens are very limited. Antibiotics such as colistin, tigecycline, fosfomycin, and aminoglycosides are often the only ones that can be used to treat carbapenem-resistant pathogens. Carbapenem may still be an option in certain circumstances. The administration of combination therapy for carbapenem-resistant pathogens is controversial. This review presents the current knowledge of available antimicrobial therapeutic options for infections due to carbapenem-resistant pathogens in Korea. (Korean J Med 2018;93:439-446)
