Escherichia coli producer of extended-spectrum beta-lactamases as causative agent of Fournier gangrene of urogenital origin associated with higher mortality

Abstract

Background: Fournier gangrene (FG) is a necrotizing fasciitis that endangers the patient's life. The objective of this study was to determine the etiology and impact of the agent isolated on wound and urine culture. Method: We performed a retrospective analysis within a cohort of 66 patients with FG of urogenital origin. The measured qualitative values were expressed as frequency and Percentage and compared with the chi square test and Fisher's test. The difference was considered statistically significant at p < 0.05. results: Patients who died had more frequent cultures of urine and wound positive for extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli: Urine, survivors 14.5% vs. deaths 44.4%; wound, 20.8% vs. 66.6% (p < 0.001). Conclusions: During the integral evaluation of the patient with FG it is essential to perform the urine and surgical wound cultures in order to initiate the antibiotic management directed at an early stage. Patients with GF who die present a greater number of cultures positive for E. coli ESBL.
