%X Fosfomycin trometamol (FT) has shown promising in vitro activity against multidrug-resistant (MDR) uropathogens; however, clinical data are limited in pediatric patients. We conducted a retrospective study to describe the clinical and microbiological outcomes of uncomplicated lower urinary tract infections (LUTIs) due to MDR Escherichia coli treated with oral FT in female adolescents. A total of 70 outpatients, with a median age of 13 years (range 12-16 years), were included. FT was initiated as definitive treatment of UTIs in all patients due to documented resistance against alternative oral agents. All patients received a single dose of 3 g oral FT. The post-treatment clinical and microbiological cure rates were 97% (68/70) and 94% (66/70), respectively. Only two (3%) patients reported mild, self-limited diarrhea. UTI relapse occurred in two (3%) patients. Our results suggest that oral FT might be an alternative option for outpatient treatment of uncomplicated LUTIs due to MDR E. coli in female adolescents.
