Urinary tract infection (UTI) is the most frequent bacterial infection diagnosed and treated by general practitioners and accounts for about 15% of antibiotic prescriptions in ambulatory medicine. World-wide raise of antibiotic resistance among uropathogens, most commonly Escherichia coli, threatens treatment of UTI. Uncomplicated UTI, the most frequent manifestation of UTI, is a benign, self-limited disease and the primary goal of treatment is symptom relief not cure. Antibiotic treatment reduces the duration of symptoms by 1-2 days from 5-6 days to 3-4 days. Symptoms of cystitis are the result of an inflammation evoked by bacterial products which stimulate the production of prostaglandins by a cyclooxygenase dependent mechanism. Therefore, we propose that symptom control with a non-steroidal anti-inflammatory drug (NSAID), an inhibitor of cyclooxygenase 1 and 2, may be equally effective for symptom control as standard antibiotic therapy in non-complicated UTI and may therefore help to reduce antibiotic consumption.
The primary objective is to determine whether initial symptomatic treatment followed by optional delayed antibiotic treatment (experimental intervention) is non-inferior to immediate antibiotic treatment followed by optional delayed antibiotic treatment (control intervention) in terms of symptom resolution.
The secondary objective is to determine whether the experimental intervention is superior to control in reducing the proportion of patients undergoing antibiotic treatment.
Randomized controlled patient and assessor blind trial performed in general practices. Study population are women between the ages of 18 to 70 years with acute uncomplicated UTI. The experimental intervention will consist of symptomatic treatment with diclofenac 75mg twice daily, followed by optional, delayed antibiotic treatment with single dose of 3g fosfomycin if deemed necessary by the patient. The control intervention will consist of immediate antibiotic treatment with norfloxacin 400mg twice daily for three days, followed by optional, delayed antibiotic treatment with single dose of 3g fosfomycin if deemed necessary by the patient. Patients will use a diary to describe symptoms for 10 days. A follow-up telephone interview will be performed on day 10 and 30.
