Anaerobic bacteremia in patients with acute leukemia.
We reviewed 402 hospital admissions of patients with acute leukemia to define the frequency and characteristics of anaerobic bacteremia in this patient population. Six (5.2%) of the 116 septicemia episodes documented in these patients were caused by anaerobes (Bacteroides species, 3; Fusobacterium species, 2; and Clostridium tertium, 1); two of these episodes were polymicrobial. Five patients had had prior bacteremia. All six patients were receiving broad-spectrum antibiotics, including an anti-pseudomonal penicillin, at the time of the episode. In each instance, the absolute granulocyte count was 0/mm3. Five patients had clinically apparent sources of infection, including perirectal abscess, gastrointestinal bleeding, or Clostridium difficile-associated diarrhea. Anaerobic bacteremia is an infrequent occurrence in granulocytopenic patients with acute leukemia, but may occur when there is obvious disruption of normal gastrointestinal anatomic barriers.
