Plazomicina en infecciones complicadas del tracto urinario multirresistentes: una revisión de alcance

Complicated urinary tract infections (cUTIs) cause significant morbidity and mortality. Multidrug-resistant (MDR) organisms complicate cUTI management, highlighting the need for effective antimicrobials.

This scoping review was conducted to assess the role of plazomicin in managing cUTIs.

This review included observational studies, clinical trials, qualitative studies, and in vitro studies published between 01 January 2018 and 15 July 2025.

Searches were conducted on PubMed, MEDLINE, EMBASE, and Google Scholar.

The screening process involved reviewing titles and abstracts, followed by full-text evaluation.

Thirty studies were included in this review. Compared with meropenem, plazomicin demonstrated superior microbiological eradication at the test of cure (TOC; 89.5%), composite cure rate at the TOC (81.7%), and comparable clinical cure rates both at the TOC (89%) and end of intravenous therapy (96.3%). Adverse events, observed in 19.5% of patients, primarily included diarrhea, nausea, and renal dysfunction, indicating a favorable safety profile. In vitro data showed susceptibility rates for plazomicin ranging from 87% to 99.8% against Enterobacteriaceae, with superior activity over gentamicin, amikacin, and tobramycin. Plazomicin demonstrated synergistic effects with colistin, meropenem, and fosfomycin against extensively drug-resistant isolates and carbapenem-resistant Enterobacteriaceae.

This review underscores plazomicin as a promising treatment for MDR cUTIs. However, limited data from low- and middle-income countries like India highlight the need for real-world studies on its efficacy, safety, and cost-effectiveness in such countries.
