Insights

Two leukemia patients developed Fusarium fungaemia, a serious bloodstream infection. This fungal infection presented solely as fungaemia in both severely neutropenic individuals.

Area of Science:

  • Mycology
  • Hematology
  • Infectious Diseases

Background:

  • Fusarium species are ubiquitous fungi that can cause opportunistic infections.
  • Severely neutropenic patients, particularly those with hematologic malignancies like leukemia, are at high risk for invasive fungal infections.
  • Fungaemia, the presence of fungi in the bloodstream, indicates a systemic infection.

Observation:

  • Two cases of Fusarium infection with fungaemia in severely neutropenic leukemia patients are presented.
  • Case 1: A 65-year-old woman with chronic lymphocytic leukemia infected by Fusarium verticillioides.
  • Case 2: A 45-year-old woman with acute myeloblastic leukemia infected by Fusarium spp.

Findings:

  • Fusarium fungaemia was diagnosed in both patients.
  • Fungaemia was the sole clinical manifestation of the fungal infection in both instances.
  • Identification of Fusarium verticillioides in one case and Fusarium spp. in the other.

Implications:

  • Highlights the potential for Fusarium species to cause life-threatening fungaemia in immunocompromised hosts.
  • Emphasizes the importance of considering Fusarium in the differential diagnosis of bloodstream infections in neutropenic patients.
  • Suggests that fungaemia may be the primary or only detectable sign of Fusarium infection in this vulnerable population.
