Abstract:
Urinary tract infections are one of the most common health problems and entail a high consumption of health system resources. Due to the increase in global antibiotic resistances in recent years, it is increasingly common to find uropathogens with multiple resistance mechanisms, including quinolone-resistant bacteria, broad-spectrum β-lactamase producers and carbapenemase producers. In this scenario, the role of fosfomycin has gained considerable importance, given its spectrum of activity against multidrug resistant microorganisms (Gram-positive and Gram-negative), becoming an attractive alternative therapy. Regarding the use of fosfomycin in complicated urinary tract infections, there is increasing clinical experience with patients with infections caused by multidrug resistant bacteria, those with recurrent urinary tract infection and special populations such as those with kidney transplants. Randomized comparative studies and series are underway, which will provide greater evidence. Nevertheless, more studies are needed to confirm the enormous potential of fosfomycin in complicated urinary tract infection in the era of multiresistance.
Insights
Fosfomycin is an effective alternative therapy for multidrug-resistant urinary tract infections (UTIs). Further studies are needed to confirm its potential in complicated UTIs amid rising antibiotic resistance.
Area of Science:
- Infectious Diseases
- Pharmacology
- Urology
Background:
- Urinary tract infections (UTIs) are a common health issue, straining healthcare resources.
- Increasing antibiotic resistance, including quinolone, β-lactamase, and carbapenemase resistance, complicates treatment.
- Multidrug-resistant uropathogens pose a significant global health challenge.
Purpose of the Study:
- To evaluate the role and efficacy of fosfomycin as an alternative therapy for UTIs.
- To highlight fosfomycin's activity against multidrug-resistant (MDR) Gram-positive and Gram-negative bacteria.
- To review current clinical experience with fosfomycin in complicated UTIs and special populations.
Main Methods:
- Review of existing clinical data and studies on fosfomycin use in UTIs.
- Analysis of fosfomycin's antimicrobial spectrum against resistant uropathogens.
- Examination of clinical experience in patients with MDR bacteria, recurrent UTIs, and kidney transplants.
Main Results:
- Fosfomycin demonstrates broad-spectrum activity against MDR microorganisms.
- Clinical experience is growing for fosfomycin in complicated UTIs, including those caused by resistant bacteria.
- Fosfomycin is emerging as a viable option for recurrent UTIs and in special patient groups.
Conclusions:
- Fosfomycin is a promising alternative therapy for complicated urinary tract infections (cUTIs) in the era of multidrug resistance.
- Increased clinical experience and ongoing studies are supporting fosfomycin's role in managing resistant UTIs.
- Further research is required to fully establish fosfomycin's efficacy and optimal use in cUTIs.
