[A case of severe septicemia due to Aeromonas hydrophila]

Septicemia by Aeromonas hydrophila (A. hydrophila) developed in a 69-year-old female with a history of uncompensated liver cirrhosis. She was admitted to our hospital, complaining of fever, vomiting, diarrhea, and pain as well as swelling of the left lower extremity. Seven hours later, skin of the left extremity developed bullae and became discolored. Although she was treated with infusion of antibiotics plus dopamine, continuous hemodiafiltration, glucose-insulin therapy and mechanical ventilation, she fell in severe septic shock, and died 23 hours after admission. A. hydrophila was isolated from both blood and bullous fluid. Mortality rate of septicemia due to A. hydrophila is reported ranging from 29% to 73%. Patients with liver disease have poor prognosis. Morbidity of this septicemia depends on pre-infection conditions, especially on liver functions. Early surgical debridement and antimicrobial therapy is recommended, but rapid worsening often results in death. We have to pay attention to infection of A. hydrophila especially in patients with liver cirrhosis.
