Abstract
INTRODUCTION: Edwardsiella tarda uncommonly infects humans. The usual presentation is mild gastroenteritis, but systemic manifestations may occur. Lethal infections are rarely documented in patients with underlying disorders. CASE PRESENTATION: A previously healthy 37-year-old Southeast Asian woman presented to our hospital with recent onset of abdominal pain, fever, and vomiting. Her condition rapidly deteriorated with signs and symptoms of fulminant septic shock; thus, she was intubated, supported with intravenous vasopressors and fluids, and transferred to the intensive care unit. An abdominal computed tomographic scan with contrast revealed multiple liver abscesses. Blood cultures were obtained and computed tomography-guided percutaneous drainage of the liver abscesses with supplementary cultures was performed; thereafter, empirical broad-spectrum antibiotics were initiated. All cultures grew E. tarda, whereas an antibiogram showed resistance to broad-spectrum antibiotics and sensitivity to ciprofloxacin and aminoglycosides; thus, the antibiotic regimen was updated accordingly. The patient made an uneventful recovery and was discharged from the intensive care unit 14 days after admission. CONCLUSION: E. tarda human infection can present as liver abscess and fulminant septic shock. E. tarda strains can be resistant to broad-spectrum antibiotics; hence, culture-based antibiotics should be used accordingly. Clinicians should be aware of this rare and potentially lethal infection.
