[Liver abscesses successfully treated by intraportal administration of amphotericin B in a case of acute myeloblastic leukemia (M2)].
A 46-year-old male was admitted to our hospital because of relapse of acute myeloblastic leukemia (M2). Remission was successfully reinduced after reinduction chemotherapy consisting of daunorubicin, cytosine arabinoside, etoposide and vincristine, but was complicated by neutropenia. After the therapy, the patient had persistent fever of about 38 degrees C despite broad-spectrum antibiotics therapy and the patient developed pain in the right quadrant of the abdomen. The white blood cell count rose to 23000/mm3. Liver function tests showed abnormal findings mainly consisting of an elevated serum alkaline phosphatase level. Ultrasonography showed multiple hypoechoic lesions in the liver and CT scans also revealed multiple low density areas. Therefore he was suspected of having a complication of liver abscesses. Amphotericin B was administered 75 mg/day intravenously every other day. A percutaneous liver biopsy was performed, but was not diagnostic. Blood cultures were negative for pathogens. Amphotericin B was administered up to a cumulative dosage of 2.3 g, but the patient remained febrile. Then he had an exploratory laparotomy and an open liver biopsy. The liver biopsy samples showed fungal elements proved by PAS staining. A catheter was inserted into the portal vein. Administration of Amphotericin B was started 20 mg daily through the catheter. The temperature fell to normal after institution of this therapy. The abnormal findings in CT scans almost disappeared and the inflammatory findings became negative after he had received intraportal administration of Amphotericin B over three months. Through the analysis of this case study, we confirmed that the intraportal administration of Amphotericin B was effective to the intractable liver abscesses due to fungi.
