A case report and review of acute cholangitis with septic shock induced by Edwardsiella tarda.

BACKGROUND

Edwardsiella tarda (E. tarda) is a gram-negative facultative anaerobic bacterium. Gastroenteritis is the most common manifestation of E. tarda infection. However, parenteral infections can occur in immunodeficient hosts, as well as hepatobiliary diseases, malignancies, and/or diabetes. The prognosis of sepsis caused by E. tarda is very worse, with a mortality rate of 38%. We report the occurrence of acute cholecystitis with septic shock and E. tarda bloodstream infection.

CASE PRESENTATION: A 64-year-old male with acute cholecystitis secondary to hepatitis B virus infection showed fever and sudden upper abdominal pain. On arrival, right upper abdominal pain, nausea, vomiting, fever, and jaundice were observed. Computed tomography showed common bile duct stones and gallbladder stones. Choledocholithiasis with acute cholangitis was diagnosed and treated surgically. Due to septic shock, a blood culture was assessed showing E. tarda as the main pathogen. Choledocholithotomy, T-tube drainage, cholecystectomy, and intravenous antibiotic treatment after the operation. The patient recovered smoothly after the operation.

CONCLUSIONS

Although E. tarda infection is extremely rare, it can cause rapid episodes of rapidly progressive and life-threatening disease, as well as intestinal and parenteral infections. If necessary, early surgical treatment of parenteral infection should be considered and antibiotics should be used in time.
