In the midst of many changes surrounding aminoglycosides over the past several years, clinicians may be left wondering if these agents still have a role in modern clinical practice. This article summarizes changes impacting aminoglycosides, discusses where these agents may still have a role in the context of gram-negative infections, and explores future areas of study.

Compared to culture/sensitivity results (C/S) results, ICU-based PCR testing of hospital-acquired pneumonia was associated with lower treatment costs and better antibiotic stewardship, but not higher cure rates.

Iterum Therapeutics has launched its sulopenem etzadroxil and probenecid (Orlynvah), which is the first and only oral penem antibiotic in the US.

Ciprofloxacin monotherapy was non-inferior to aminoglycoside/ciprofloxacin combination for bubonic plague in multi-year trial in endemic region.

The NARROWS framework, developed within the IDSA Core Antimicrobial Stewardship Curriculum, provides a structured, behaviorally informed approach to communication that helps stewardship teams address the social, emotional, and cultural factors influencing prescribing decisions in order to optimize antimicrobial use and combat resistance.

Stenotrophomonas maltophilia is an opportunistic, multidrug-resistant pathogen that poses significant treatment challenges due to its complex resistance mechanisms, limited therapeutic options, and high mortality rates among vulnerable patients.

Clinical trial and real-world data, including the PROVE study, support its role as an effective and carbapenem-sparing therapy for serious infections, though outcomes vary depending on pathogen and infection type.

Doxycycline postexposure prophylaxis is associated with emerging tetracycline resistance in Neisseria gonorrhoeae and commensal organisms, highlighting the need for cautious, targeted use.
