Abstract:
There is an increasing prevalence of urinary tract infection (UTI) caused by multiresistant gram-negative enteric bacilli such as extended-spectrum beta-lactamase as well as Gram-positive enterococci whose vancomycin-resistance can be as high as 25%. We report on a 68-year-old Caucasian female with a UTI caused by a vancomycin-resistant Enterococcus faecium, only tested to be susceptible to gentamycin, linezolid and daptomycin. Within a day after administration of the bactericidal daptomycin clinical and laboratory signs of infection regressed and graft function recovered. Our case suggests that daptomycin might be an effective alternative for UTI caused by vancomycin-resistant enterococci.
Insights
This case study highlights daptomycin as a potential treatment for urinary tract infections (UTIs) caused by vancomycin-resistant Enterococcus faecium. Early administration of daptomycin led to rapid clinical improvement and graft function recovery.
Area of Science:
- Infectious Diseases
- Nephrology
- Pharmacology
Background:
- Increasing prevalence of multidrug-resistant Gram-negative bacilli and Gram-positive enterococci causing urinary tract infections (UTIs).
- High rates (up to 25%) of vancomycin resistance in enterococci pose significant treatment challenges.
Purpose of the Study:
- To report a case of UTI caused by vancomycin-resistant Enterococcus faecium (VRE).
- To evaluate the efficacy of daptomycin in treating VRE-UTI.
Main Methods:
- A 68-year-old female patient with VRE-UTI was treated with daptomycin.
- Clinical and laboratory parameters were monitored following daptomycin administration.
Main Results:
- The patient's UTI was caused by vancomycin-resistant Enterococcus faecium, susceptible only to gentamycin, linezolid, and daptomycin.
- Within 24 hours of daptomycin treatment, clinical and laboratory signs of infection significantly regressed.
- Graft function also recovered following daptomycin therapy.
Conclusions:
- Daptomycin demonstrated rapid clinical and laboratory efficacy in this VRE-UTI case.
- Daptomycin may represent an effective therapeutic alternative for UTIs caused by vancomycin-resistant enterococci.
