Prevalencia etiológica de infección del tracto urinario en gestantes sintomáticas, en un hospital de alta complejidad de medellín, Colombia, 2013-2015

Objective: To determine the prevalence of urinary tract infections (UTIs), the microbiological profile and antibiotic resistance in pregnant women with suspected urinary tract infection. Materials and methods: Cross-sectional study of pregnant women with suspected communityacquired urinary tract infection referred to the outpatient clinic by prenatal care practitioners or seen in the emergency room, and hospitalized between August 2013 and September 2015 in a referral teaching hospital located in Medellin, Colombia. Pregnant women who had received antibiotics on the day before admission were excluded. Random sampling. Measured variables: sociodemographic, clinical and bacteriological. Descriptive statistics were applied. Results: The prevalece of urinary tract infections was 29%. Gram negative bacteria isolates were found predominantly, the main ones being E. coli and K. pneumoniae at 57.7 and 11.4%, respectively. Resistance to trimethoprim- sulfamethoxazole and to ampicillin-sulbactam was observed in 19.5% and 17.5% of isolates, respectively. Conclusions: Population-based studies are needed to provide a better approach to bacterial resistance in community-acquired UTIs. On the other hand, the high resistance observed may suggest that some of the exposed antibiotics might not be included in the local guidelines for the management of UTIs.
