Randomized clinical trial in which women aged 18 or older and with symptoms of uncomplicated lower urinary tract infection and a positive urine dipstick analysis will be randomized to one of the following four groups: 2-day 3 g fosfomycin o.d., 3-day pivmecillinam 400 mg. t.i.d, 5-day nitrofurantoin 100 mg t.i.d. or a single dose of 3 g of fosfomycin. Sample: 1,000 patients. Two co-primary endpoints are considered: clinical effectiveness at day 7 and bacteriological eradication at day 14. Follow-up visits are scheduled at days 7 (phone call), 14 and 28 for assessing evolution. Urine samples will be collected in the three on-site visits and urine cultures performed.
Uncomplicated lower urinary tract infections (LUTI) represent a common problem in primary care. Resistance of uropathogens to common antibiotics has significantly increased in the last years. Current local guidelines recommend the use of a single 3 g dose of fosfomycin for these infections, but most general practitioners prefer short-course therapies to single-dose therapy. No study has compared head-to-head short course antimicrobial agents for uncomplicated LUTIs. Therefore, the aim of this randomized clinical trial is to compare three different short-course antibiotic therapies with single-dose fosfomycin for uncomplicated LUTIs in adult women. This will be a pragmatic, multicenter, parallel group, open randomized trial. Women aged 18 or older and with symptoms of uncomplicated LUTI and a positive urine dipstick analysis will be randomized to one of the following four groups: 2-day 3 g fosfomycin o.d., 3-day pivmecillinam 400 mg. t.i.d, 5-day nitrofurantoin 100 mg t.i.d. or a single dose of 3 g of fosfomycin. Sample: 1,000 patients. Two co-primary endpoints are considered: clinical effectiveness, defined as resolution of symptoms, answered by the patients at day 7, and bacteriological eradication (proportion of patients bacteriologically cured) at day 14. Patients will be given a symptom diary for seven days. Follow-up visits are scheduled at days 7 (phone call), 14 and 28 for assessing evolution. Urine samples will be collected in the three on-site visits and urine cultures performed. If positive, antibiograms for the 3 antibiotics studied will be performed.
