Aeromonas hydrophila Sepsis Associated with Consumption of Raw Oysters.

Introduction. Aeromonas hydrophila is a gram negative bacillus that is native to aquatic environments that is increasingly reported in humans. This case is remarkable for A. hydrophila with an initial presentation of acute pancreatitis. Case Presentation. A 61-year-old male presented to the emergency department with nausea, vomiting, and abdominal pain for two days. His past medical history was significant for alcohol abuse. Initial laboratory examination showed an elevated white blood cell count, elevated lipase, and elevated liver function tests (LFT). Computer tomography (CT) showed peripancreatic inflammatory changes and retroperitoneal free fluid, suggestive of acute pancreatitis. The patient was treated with intravenous (IV) fluids and IV meropenem. After two days, the patient developed sepsis and respiratory failure and was intubated. Blood cultures were positive for Aeromonas hydrophila sensitive to ciprofloxacin which was added to his treatment. Additionally, it was discovered that this patient had recently vacationed in Florida where he consumed raw oysters. He was discharged home on the eighth day of the hospital admission. Conclusion. This is a rare case of A. hydrophila sepsis in an elderly patient with acute pancreatitis and a history of consumption of raw oysters. This case suggests that A. hydrophila can cause disseminated infection in immunocompetent individuals.
