Single-dose cefonicid therapy for urinary tract infections

Area of Science:

• Infectious Diseases
• Pharmacology
• Urology

Background:

• Uncomplicated lower urinary tract infections (UTIs) are common in women.
• Conventional treatment often involves multidose oral antibiotics like amoxicillin.
• Exploring alternative, potentially more convenient, therapeutic regimens is warranted.

Purpose of the Study:

• To compare the efficacy and safety of single-dose intramuscular cefonicid with multidose oral amoxicillin for uncomplicated lower UTIs in women.
• To assess early and late posttherapy cure rates.
• To evaluate the incidence of side effects and antimicrobial resistance patterns.

Main Methods:

• A randomized study comparing single-dose cefonicid (1g IM) versus 7-day multidose amoxicillin (500mg TID PO).
• Participants were women with symptomatic lower UTIs, with bacterial confirmation (≥10^5 CFU/ml) in a subset.
• Clinical cure rates were assessed at early (5-18 days) and late (6-7 weeks) follow-up points.

Main Results:

• High early cure rates: 90% for cefonicid (19/21) and 89% for amoxicillin (16/18).
• Sustained late cure rates: 89% for cefonicid (16/18) and 93% for amoxicillin (14/15).
• Cefonicid group experienced fewer side effects and demonstrated lower rates of bacterial resistance compared to amoxicillin.

Conclusions:

• Single-dose cefonicid is as safe and effective as multidose amoxicillin for treating uncomplicated lower UTIs in women.
• Cefonicid offers a convenient alternative with a favorable side effect profile.
• Reduced resistance to cefonicid suggests potential advantages in antimicrobial stewardship.
