Zusammenfassung:Purpose This study aimed to report a case of acute myeloid leukemia (AML) complicated by Aeromonas veronii infection-induced bacteremia and to review relevant literature on the etiology, prevention, treatment, and prognosis of bacteremia in immunocompromised populations, aiming to reduce mortality in individuals with hematologic and other end-stage diseases and improve patient outcomes. Methods and results We reported the case of a 23-year-old male patient with relapsed AML characterized by AML1:ETO and ASXL positivity, classified as a high-risk group. The patient presented with fever, abdominal pain, diarrhea, nausea, and vomiting after consuming partially cooked fish. The patient was admitted with high leucocytes, C-reactive protein, procalcitonin, and interleukin-6 levels. Peripheral blood high-throughput sequencing (Next-Generation Sequencing NGS) confirmed infection with Aeromonas veroni i, while an abdominal CT scan indicated a liver abscess with gas formation. Culture of the drainage fluid from the ultrasound-guided liver abscess puncture demonstrated growth of Aeromonas veronii . Based on the sensitivity results, the patient was treated with intravenous ciprofloxacin and cefoperazone-sulbactam. After treatment with antibiotics, blood transfusion, liver protection, and azacitidine 100 mg ih, combined with dry white sand(interferon alpha-1B, interleukin-2, and thalidomide), the critical condition of the patient improved, and he was discharged. This study was approved by the Ethics Committee of Medical Research in the Second Affiliated Hospital of Henan University of Science and Technology. Informed consent was obtained from this patient and we have obscured the patient's identifying information. All methods were carried out in accordance with relevant guidelines and regulations. Conclusion When patients with a recurrence of AML have a history of consuming or contacting aquatic products, clinicians should be vigilant about Aeromonas veronii infection. The presence of Aeromonas veronii in peripheral blood must alert clinicians to the possibility of severe sepsis and septic shock. Early diagnosis and prompt treatment are crucial to reducing patient mortality.
