Fungemia in Patients with Leukemia

A nine-year retrospective study on fungemia in patients with leukemia was conducted. A total of 79 episodes of fungemia in 77 patients with leukemia were documented. Candida parapsilosis fungemia was associated more frequently with the presence of a central venous line and to the use of parenteral nutrition than the other fungal species (p = 0.00026 and p = 0.01, respectively). The same fungus was isolated from both blood and surveillance cultures in 95% of Candida albicans and in 89% of Candida tropicalis fungemia (p < 0.01 and p = 0.02, respectively). The neutropenia and fungus colonization that resulted was associated significantly with the presence of invasive disease (p = 0.0024 and p = 0.0028, respectively). Conversely, central venous catheterization and parenteral nutrition appeared to be associated with episodes without deep tissue invasion (p = 0.000037 and p = 0.001, respectively). Invasive mycosis due to the fungus isolated from blood was documented in 51 patients with a mortality rate of 6970, whereas in 20 patients without invasive mycosis, mortality rate was 21% (p = 0.000059). In patients with fungemia, related or unrelated to the presence of a central venous catheter, mortality was 24% and 6470, respectively (p = 0.00042). Mortality was highest with C. tropicalis (p = 0.0017) and lowest with C. parapsilosis (p = 0.057). Severe neutropenia (polymorpho-nuclears < 100/mmc) appeared associated with a higher mortality rate (p = 0.012), whereas the recovery of neutropenia was related adversely to a fatal outcome (p < 0.01). With antifungal therapy, there was no statistically significant difference whether antifungal therapy was given or not. This study confirms the major roles of neutropenia, previous colonization, and the central venous catheter as predisposing factors in the development of fungemia in patients with leukemia. The prognosis of patients with fungemia depends on the presence of a deep infection, on the recovery of neutropenia, and on the species of fungus involved.
