Real-World Experience With Maribavir for Treatment of Refractory or Resistant Cytomegalovirus Infection in Hematopoietic Cell Transplant Recipients and Hematologic Malignancy Patients.

Background: Refractory and/or resistant (R/R) cytomegalovirus (CMV) infection is a serious complication after allogeneic hematopoietic cell transplantation (HCT). Maribavir, an oral antiviral agent, was approved in November 2021 for the treatment of R/R CMV in transplant recipients. However, real-world data on the use of maribavir in HCT recipients and hematologic malignancy (HM) patients are limited.

The Utility of Interferon-γ Release Assays in the Diagnosis of Tuberculosis in Patients With Cancer.

Background: Patients with cancer are at elevated risk for tuberculosis (TB) reactivation. Diagnosis of latent TB infection and TB disease remains challenging in this patient population despite the advent of interferon-γ release assays (IGRA).

Methods: We retrospectively reviewed medical records of all patients with cancer who had IGRA testing (QuantiFERON-TB [QFT-TB] or T-SPOT.

Humoral Immunity and Antibody Responses against Diphtheria, Tetanus, and Pneumococcus after Immune Effector Cell Therapies: A Prospective Study.

Patients undergoing immune effector cell therapy (IECT) are at high risk for infections. We assessed seropositivity against pneumococcus, tetanus, and diphtheria in patients before and after IECT and the patients' response to vaccination. We enrolled patients who underwent IECT from January 2020 to March 2022.

Cytomegaloviral Infections in Recipients of Chimeric Antigen Receptor T-Cell Therapy: An Observational Study With Focus on Oncologic Outcomes.

Background: Patients with B-cell lymphoma and acute lymphoblastic leukemia (ALL) who receive chimeric antigen receptor T-cell (CAR-T) therapy may experience clinically significant cytomegalovirus infection (CS-CMVi). However, risk factors for CS-CMVi are not well defined. The aims of our study were to identify risk factors for CS-CMVi and the association between CS-CMVi and nonrelapse mortality (NRM) in lymphoma and ALL patients after CAR-T therapy.

Disseminated Histoplasmosis in a Patient with Myelofibrosis on Ruxolitinib: A Case Report and Review of the Literature on Ruxolitinib-Associated Invasive Fungal Infections.

Ruxolitinib, a selective inhibitor of Janus kinases, is a standard treatment for intermediate/high-risk myelofibrosis (MF) but is associated with a predisposition to opportunistic infections, especially herpes zoster. However, the incidence and characteristics of invasive fungal infections (IFIs) in these patients remain uncertain. In this report, we present the case of a 59-year-old woman with MF who developed disseminated histoplasmosis after seven months of ruxolitinib use.
