研究概览

简要总结

The goal of this clinical trial is to learn if the drug Nitrofurantoin (NF) taken as a daily antibiotic, works to treat cystitis compared to electrofulguration (EF) and Nitrofurantoin (NF) daily antibiotic.

详细描述

This is a study for women age 18 -85 with a well-documented history of rUTI (recurrent urinary tract infection) for at least one year. This randomized multicentric clinical trial will determine the efficacy of conventional 6 months Nitrofurantoin (NF) daily antibiotic prophylaxis alone versus electrofulguration (EF) associated with a 6 months NF daily antibiotic prophylactic course for early stages of chronic cystitis (stages 1 and 2) as determined on office cystoscopy.

This study will ask the participant (n=104) to return to the Urology clinic at UT Southwestern Medical Center (n=52) or The University of Kansas Medical Center (n=52) for a total of 8 compensated visits throughout 30 months after the start of this randomized trial to make sure that the treatment worked well for them.

入选标准

  • Females 18 to 85 years old with at least a 1-year history of culture documented uncomplicated rUTI.
  • Diagnosis of rUTI, defined as ≥ 3 symptomatic UTIs in 12 months or ≥ 2 in 6 months.
  • Currently free from a UTI determined based on absence of symptoms as determined by the UTI symptom assessment questionnaire and negative urine culture (<10^3 colony forming units per ml of urine).
  • A negative upper and lower urinary tract evaluation, including pelvic examination for pelvic organ prolapse (less than or equal to stage 2), measurement of post-void residual (less than 50 ml), and imaging (which may include renal ultrasound and standing voiding cystourethrogram) to exclude kidney stone, hydronephrosis, reflux, or urethral diverticulum.
  • Office cystoscopy documenting stages 1 or 2 of chronic cystitis.
  • Likely to stay in the geographic region for the duration of the study.
  • ASA class II or less.

排除标准

  • Patients on antibiotics at baseline (i.e., suppressive therapy or antibiotic therapy for non-urinary infections).
  • Patients on self-start therapy (i.e., taking antibiotics upon start of urinary symptoms concerning for UTI).
  • Patients on prophylactic antibiotics started in the last 3 months and unwilling to discontinue, or intention to start in the next 12 months.
  • Complicated UTIs, including neurogenic bladder condition (i.e., multiple sclerosis, Parkinson's disease, spinal cord injury), bladder augmentation, or urinary diversion.
  • Patients with urinary catheters (including indwelling Foley, intermittent catheterization, and suprapubic catheters).
  • Uncontrolled diabetes (HbA1c >9).
  • Pregnancy
  • Allergy or resistance to Nitrofurantoin.
  • Chronic lung or liver condition precluding the use of Nitrofurantoin, including abnormal chest X ray or elevated liver function tests.
  • Chronic renal insufficiency (creatinine over 1.5 g/dl or GFR less than 40) precluding the use of Nitrofurantoin.
  • History of chronic diarrhea requiring regular therapy.
  • Patients with psychosis, dementia, swallowing disorders, or any other ability to take Nitrofurantoin reliably at home.
  • Use of Uromune or other vaccine approaches to reduce rUTI episodes
  • Participation in a research study involving an investigational product in the past 12 weeks.
  • Patients receiving phage therapy.
  • Current diagnosis of interstitial cystitis.
  • Patients with medical conditions requiring excessively large amounts of fluid intake.
