title: [Clinical Study of Acute Uncomplicated Cystitis].
abstract: Escherichia coli is the most commonly isolated bacterium in urinary tract infections, especially in acute uncomplicated cystitis. It is reported that fluoroquinolone-resistant E. coli is increasing. However, according to the guidelines for antimicrobial use published by the Japanese Associations for Infectious Diseases (JAID) and the Japanese Society of Chemotherapy (JSC) in 2014, the first line antimicrobial regimen for the treatment of acute uncomplicated cystitis is a 3-day regimen with fluoroquinolone. We analyzed the causative bacteria and clinical efficacy of antimicrobial treatment in acute uncomplicated cystitis cases at our institute. Patients diagnosed as having acute uncomplicated cystitis who had ≥ 10(4) colony-forming units/mL of bacteria in their midstream urine in our outpatient clinic between 2012 and 2013 were enrolled in this study. We analyzed their clinical data retrospectively. From 173 patients, 212 strains were isolated. Of these, 135 (63.7%) were E. coli, including 15 strains (11.1%) that were levofloxacin resistant. One hundred twenty-three patients (63.7%) were treated with cephalosporin, and 46 patients (26.6%) were treated with fluoroquinolone. In all, 140 patients (80.9%) visited the outpatient clinic for an average of 8.4 days after their treatment. For 130 patients (92.6%), the clinical outcomes of antimicrobial treatment were judged as effective. The clinical outcomes were effective in 92.1% of the patients with cephalosporin treatment and in 97.1% of those with fluoroquinolone treatment. Only one patient who had levofloxacin-resistant E. coli in her urine was treated with fluoroquinolone. The clinical outcome was effective. Of the E. coli isolated from acute uncomplicated cystitis patients, 11.1% were levofloxacin-resistant strains. However, the clinical efficacy of antimicrobial treatment was relatively high (92.9%) in this study. The antimicrobial treatment for acute uncomplicated cystitis recommended by the guidelines published by the JAID and JSC was effective in the current situation.
