Article Synopsis
- - The IA-DUET study compared the effectiveness of a combination treatment of azole and echinocandin against azole-only treatment for invasive aspergillosis.
- - Challenges in recruiting participants included high rates of patient ineligibility, the presence of competing studies, and existing guidelines that preferred combination treatment when azole resistance wasn't determined.
- - The low mortality rate linked to invasive aspergillosis indicates that future research may be more effective by using cluster randomization or composite endpoints to improve trial efficiency.
Adverse outcomes of viral respiratory tract infections (RTIs) have been reported in recipients of allogeneic hematopoietic cell transplantation. Using a laboratory-developed multiparameter polymerase chain reaction in a consecutive series of 242 patients, we found the highest incidence of viral RTI in the preengraftment phase. The occurrence of multiple episodes of viral RTI or viral pneumonia was significantly associated with a higher hazard of nonrelapse mortality in the first year after transplantation.

In recent years, immunologic monitoring using CMV commercially available IFN-γ release assays (IGRAs) has gained interest to better risk-stratify immunocompromised patients or to guide prophylactic therapy. CMV-IGRA can quantify CMV cell-mediated immunity by measuring the IFN-γ that is released by CD4 and CD8 T lymphocytes in the presence of CMV antigens.

Methods: This was a single-center retrospective study of 140 consecutive allogeneic HCT recipients. Infectious diarrhea was assessed using a laboratory-developed multiplex polymerase chain reaction the first year after transplantation.
Background: Empiric antifungal therapy is considered the standard of care for high-risk neutropenic patients with persistent fever. The impact of a preemptive, diagnostic-driven approach based on galactomannan screening and chest computed tomography scan on demand on survival and on the risk of invasive fungal disease (IFD) during the first weeks of high-risk neutropenia is unknown.
Methods: Patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) and allogeneic hematopoietic cell transplant recipients were randomly assigned to receive caspofungin empirically (arm A) or preemptively (arm B), while receiving fluconazole 400 mg daily prophylactically.
