title: [Risk factor for invasive zygomycosis in patients with hematologic malignancies].
abstract: Zygomycosis (mucormycosis) is a relatively uncommon infection in immunocompromised patients most often diagnosed in patients with haematological malignancies and neutropenia. Postmortem series demonstrate a high mortality rate up to 80%. Pulmonary involvement mimicking the more frequently diagnosed invasive aspergillosis is the typical clinical presentation. Other risk factors for the development of zygomycosis that have been described in other patient populations include diabetic ketoacidosis, iron overload, use of deferoxamine and steroids. If these factors are also associated with zygomycosis in patients with haematological malignancies has not been described. In a retrospective case-control study including 13 patients with zygomycosis and 13 control patients with the same underlying diseases, without zygomycosis we determined the frequency of various risk factors. Patients with zygomycosis experienced a longer period of neutropenia (17 vs. 13 days) and lymphopenia (23 vs. 20 days). A relapse of their underlying disease was diagnosed more frequently in patients with zygomycosis (7/13 vs. 3/13) as were a diagnosis of diabetes mellitus (6/13 vs. 3/13) and a cardiovascular disease (6/13 vs. 1/13). The previous use of steroids was more frequent in patients with zygomycosis (8/13 vs. 4/13) as was a systemic antifungal prophylaxis with itraconazole (9/13 vs. 4/13). Knowledge of these risk factors may be of benefit in diagnosing and monitoring zygomycosis in patients with haematological malignancies.
