Validation of an Index of Neutropenia (D-index) in Febrile Neutropenic Cancer Patients
Invasive Fungal InfectionsInvasive Aspergillosis1 moreThe main objective of this study is to test prospectively the performance of an algorithm stratified by an index based on neutrophil counts in association with galactomannan assay and image tests to start an antifungal early therapy (empirical/preemptive) in neutropenic patients. Ths specific objectives are to determine the overall incidence of invasive fungal infections, use of antifungal agents, duration of hospitalization and mortality in this cohort, and to evaluate if this strategy is associated with a reduction in the expected use of antifungal agents if a classical empiric antifungal strategy was used, without an increase in the incidence of invasive fungal infections. This is a prospective, non randomized, non comparative study. Patients aged ≥ 18 years are eligible if they have acute leukemia, myelodysplasia or other baseline disease submitted to chemotherapy or to allogeneic stem cell transplantation with an expected duration of neutropenia (neutrophil count <500cells/mm³) of at least 10 days. Exclusion criteria are patients with and a past history of or invasive mold infection and those who do not want to participate. The study has no comparator arm. However, the investigators intend to determine if the algorithm based on the D-index would result in a 50% reduction in the use of antifungal agents, if all patients with persistent fever and neutropenia received empiric antifungal therapy. Based on our database of ~2,000 episodes of febrile neutropenia, 36% of patients had persistent fever between days 4 and 7 of antibiotics and would receive empiric antifungal therapy. A total of 105 patients will be needed to demonstrate a 50% reduction in antifungal use if the investigators compared this cohort with a matched control historical cohort (alpha = 5%, beta = 20%).
Markers of Infection and Resistance in Invasive Fusariosis
FusariosisIn recent decades, invasive fusarioses have been emerging fungal pathologies with high mortality. The prognosis depends on the speed of the diagnosis, but currently biological diagnosis is mainly based on fungal culture, no specific biomarker for this microorganism is available in current clinical practice. The genus Fusarium also shows reduced sensitivity to antifungals commonly used and recommended in clinical practice, such as voriconazole or amphotericin B. The main objective of this study is to describe the proportions of different fungal species in positive fungal cultures in patients with invasive fungal infection (IFI) or fungal keratitis. The secondary objectives are the description of the dosage of galactomannans, beta (1,3) -D-glucans and the rate of detection of DNA circulating in case / control groups for the 2 clinical forms studied. In patients with evidence of Fusarium wilt, the study will describe the distribution of the different minimum inhibitory concentrations (MIC) depending on whether or not different antifungals are taken, the vital status at 3 months, and the response or not to treatment. Finally, the presence of genetic markers will be described according to the groups of MIC values.
Anti-mold Azole in the Prophylaxis for Invasive Fusariosis
FusariosisOnychomycosisPatients admitted for autologous or allogeneic hematopoietic cell transplantation, induction-remission chemotherapy for acute myeloid leukemia, myelodysplasia or acute lymphoid leukemia, or to receive immunosuppressive therapy for aplastic anemia will be screened with dermatologic examination. In the presence of any skin lesion in the extremities, direct exam and fungal culture will be performed. If these exams indicate the presence of Fusarium species, patients will receive anti-mold azole prophylaxis
Fusariosis in Solid-Organ Transplant Recipients
Solid Organ TransplantFusariosisThis exempt chart review study will try to determine the clinical presentation, prognostic factors, response to different treatment modalities and mortality among patients diagnosed with fusariosis after solid-organ transplantation.
