A case of necrotizing fasciitis following Edwardsiella tarda septicemia with gastroenteritis.
Journal of Infection and Chemotherapy(2019)
摘要
Edwardsiella tarda is an uncommon pathogen that causes gastroenteritis in humans and is found in the aquatic environment. In rare cases, it also causes fatal infections, including sepsis and necrotizing fasciitis. However, it remains unknown whether E. tarda gastroenteritis could lead to these lethal diseases via hematogenous spread. Here we have reported a previously healthy 64-year-old woman with necrotizing fasciitis consecutively caused by E. tarda septicemia with gastroenteritis. The patient was transferred to the emergency department due to disturbance of consciousness and hypotension after suffering from diarrhea for a month. As whole-body computed tomography (CT) revealed an edematous change in the small intestine, septic shock following gastroenteritis was suspected, and the patient was immediately started on empiric antibiotic therapy and provided critical care. Her general physical conditions gradually began improving, but, on day 7, rapidly appearing blisters on both the lower limbs were noted, and she was accordingly examined again by conducting a CT scan. Based on the results, she was diagnosed with necrotizing fasciitis in both lower extremities, and surgical debridement was rapidly performed. Microbiological analysis of the specimens revealed E. tarda bacteremia, which suggested that E. tarda caused a series of infections in this patient. Finally, she fully recovered and was discharged within 3 months. Cumulatively, we proposed that gastroenteritis by E. tarda could directly result in fatal infections through the blood stream.
