The clinical and epidemiologic spectrum of 175 cases of community-acquired urinary tract infection (UTI) were evaluated at a university hospital.
Patients were grouped in five different categories of which complicated UTI was the most common (39%). Bacteraemia was detected in eight patients (18%) of this group and in five (12%) with acute uncomplicated pyelonephritis.
A single organism was isolated in 166 cases (95%). The rate of Escherichia coli bacteriuria ranged from 60% (asymptomatic bacteriuria) to 94% (uncomplicated cystitis).
Of the 184 isolates, 92% were susceptible to ciprofloxacin and significantly high rates of resistance were found for ampicillin, cefazolin, cefuroxime, and co-trimoxazole.
Isolates causing uncomplicated UTI had significantly high rates of resistance to ampicillin, amoxycillin-clavulanate and co-trimoxazole and those causing complicated UTI, had significantly high rates of resistance to most oral antibiotics tested, except quinolones and nitrofurantoine.
Community-acquired UTI requiring hospital evaluation occurs in a complex group of patients, and current patterns of antibiotic resistance make it difficult to suggest empiric oral treatments in this setting.
