Clinical Effectiveness and Bacteriological Eradication of Three Different Short-course Antibiotic Regimens and Single-dose Fosfomycin for Uncomplicated Lower Urinary Tract Infections in Adult Women.

IJG-SCOUT-2021

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.

Inclusion Criteria: Women of 18 years of age or older, with clinical features of uncomplicated community-acquired lower urinary tract infection including: * At least one of four key symptoms of lower urinary tract infection: dysuria, urgency including nycturia, frequency, and suprapubic tenderness that could be attributed to an uncomplicated lower urinary tract infection, and no alternative explanation (i.e. symptoms suggestive of sexually-transmitted infection or vulvovaginitis), and * A urine dipstick analysis positive for either nitrites or leukocyte esterase. Exclusion Criteria: * Male sex * High suspicion of pyelonephritis (i.e. fever ≥ 37.5°C or flank pain/tenderness) * Any condition that may lead or predispose to complicated urinary infection (i.e. indwelling urinary catheter, pregnancy, immunosuppressive therapy, abnormal urinary tracts, recurrent urinary tract infection, severe neurological disease affecting the bladder) * Pregnancy or planned pregnancy * Symptoms consistent with urinary tract infection in the preceding 4 weeks * Patients taking long-term antibiotic prophylaxis * Ongoing antibiotic therapy or use of any systemic antibiotic in the previous 7 days * Symptoms correlating with differential diagnosis (i.e. vaginal discharge or pain) * Hypersensitivity or allergy to β lactams, nitrofurantoin and/or fosfomycin * Moderate to severe chronic renal insufficiency * Pre-existing polyneuropathy * History of lung or liver reaction or peripheral neuropathy after previous use of nitrofurantoin * Glucose-6-phosphate dehydrogenase deficiency * Porphyria or systemic primary carnitine deficiency or of the type organic aciduria (i.e. methylmalonic aciduria and propionicacidaemia) * Esophageal stricture * Current intake of allopurinol or probenecid or valproate * Currently part of another randomized clinical trial * Previous enrolment in the proposed study * Patients living in long-term institutions; and/or * Difficulty in conducting scheduled follow-up visits
