[ASPERGILLUS CENTRAL VENOUS CATHETER INFECTION WITH FUNGEMIA IN A PATIENT UNDERGOING HEMODIALYSIS - CASE REPORT].

Aspergillus species are an important cause of life-threatening infections in immunocompromised patients. Those considered at high risk include patients with prolonged neutropenia, and patients who underwent bone marrow transplantation. The most common presentation of aspergillosis is invasive aspergillosis (IA) with pulmonary involvement.

Letermovir for Prevention of Recurrent Cytomegalovirus in High-Risk Allogeneic Hematopoietic Cell Transplantation Recipients.

We evaluated letermovir (LTV) for secondary prophylaxis for cytomegalovirus (CMV) in allogeneic hematopoietic cell transplant recipients (HCT) at high-risk for CMV recurrence. This open-label study was conducted at Memorial Sloan Kettering Cancer Center and the University of Minnesota. Patients with clinically significant CMV infection (cs-CMVi) and ≥1 high-risk criteria for CMV who achieved viral suppression with standard CMV antivirals received LTV secondary prophylaxis for up to 14 weeks.

Impact of discontinuing routine fluoroquinolone prophylaxis in neutropenic allogeneic haematopoietic stem cell transplant recipients: an observational study.

Background: Uncertainty exists as to the role of fluoroquinolone (FQ) prophylaxis for patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) in the era of rising antibiotic resistance.

Objectives: We aimed to evaluate rates of bloodstream infections (BSI), resistance patterns and outcomes of patients after discontinuing routine FQ prophylaxis administration.

Methods: All adult recipients of first HSCT from 2017 to 2020 were retrospectively included and classified according to time of HSCT as FQ group (HSCT January 2017-December 2018) or no FQ group (January 2019-December 2020).

Eosinophilic Pleocytosis in the Cerebrospinal Fluid following CAR-T Cell Therapy for Central Nervous System Lymphoma: A Case for Warning?

Introduction: Chimeric antigen receptor T (CAR-T) cell therapy, emerging as an efficient treatment option for patients with secondary central nervous system (CNS) lymphoma, is frequently complicated with immune effector cell-associated neurotoxicity syndrome (ICANS).

Case Presentation: We report a case of a 64-year-old woman with transformed follicular lymphoma, developing high-grade ICANS with eosinophilic pleocytosis following third-line therapy with CAR-T cells (tisagenlecleucel). During bridging therapy, she declined neurologically and was diagnosed with secondary CNS lymphoma.

Clinical impact of fungal colonization of burn wounds in patients hospitalized in the intensive care unit: a retrospective cohort study.

Background: Invasive fungal infections in burn victims significantly increase mortality and hospitalization. The effect of fungal burn wound colonization has not been established.

Methods: All adult patients hospitalized in the intensive care unit (ICU) with burns ≥10% of total body surface area (TBSA) between 2005 and 2021 were included.

Charting a path forward: Promising outcomes of convalescent plasma therapy in the care of severely B-cell depleted patients with persistent COVID-19.

Background: Patients with severe B-cell depletion related to hematological malignancies or B-cell targeted therapy suffer from impaired antibody responses to SARS-CoV-2 and are at risk for prolonged COVID-19. In this population, COVID-19 convalescent plasma (CCP) may provide passive immunity, enhance immune response, and promote virus neutralization. This study evaluated outcomes of B-cell depleted patients with persistent COVID-19 treated with CCP.

External Validity of a Randomized Controlled Trial on Duration of Antibiotics for the Treatment of Gram-Negative Bacteremia.

Introduction: Reports regarding the external validity of randomized controlled trials (RCTs) are scarce. We aimed to assess the population external validity of an investigator-initiated RCT on the duration of antibiotics for the treatment of Gram-negative bacteremia by comparing patients included in the RCT to patients that were not included in the trial.

Methods: Hospitalized patients with Gram-negative bacteremia were recruited into an RCT and randomized to receive 7 or 14 days of covering antibiotic therapy in Israel and Italy from 2013 to 2017.

Outcomes of Refractory Cytomegalovirus Infection in the First Year after Allogeneic Hematopoietic Cell Transplantation.

Outcomes of refractory (Rf) cytomegalovirus (CMV) infection (CMVi) after hematopoietic cell transplantation (HCT) are poor owing to limited treatment options and treatment related toxicities. Maribavir, an orally bioavailable CMV antiviral, was recently approved for treatment of Rf-CMVi. Real-world studies quantifying the burden of Rf-CMVi prior to maribavir provide a benchmark for evaluating the net value of novel treatments.

Implementing Lean Techniques to Increase the Efficiency of a Rural Primary Care Clinic: A Prospective Controlled Study.

Background: Lean, a management approach focused on identifying and eliminating waste, has been proposed as a solution for shortages in health care. Many studies implementing Lean in health care have lacked adequately designed controls.

Methods: This was a prospective, block randomized, controlled study conducted in a single primary care clinic comprising three primary care providers.

COVID-19 in Patients with Hematologic Malignancies: Clinical Manifestations, Persistence, and Immune Response.

Background: The clinical presentation of coronavirus disease 19 (COVID-19) is the result of intricate interactions between the novel coronavirus and the immune system. In patients with hematologic malignancies (HM), these interactions dramatically change the clinical course and outcomes of COVID-19.

Summary: Patients with HM and COVID-19 are at an increased risk for prolonged viral shedding, more protracted and severe presentation, and death, even when compared to other immunocompromised hosts.

Impact of Letermovir Primary Cytomegalovirus Prophylaxis on 1-Year Mortality After Allogeneic Hematopoietic Cell Transplantation: A Retrospective Cohort Study.

Background: Cytomegalovirus (CMV)-seropositive (R+) hematopoietic cell transplant (HCT) recipients have a survival disparity compared with CMV-seronegative recipient/donor (R-D-) pairs. We hypothesized that primary letermovir prophylaxis (LET) may abrogate this disparity. We investigated the relationship between LET and mortality at 1 year post-HCT.

Omitting Ciprofloxacin Prophylaxis in Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplantation and Its Impact on Clinical Outcomes and Microbiome Structure.

Fluoroquinolone prophylaxis during allogeneic hematopoietic stem cell transplantation (allo-HSCT) reduces bloodstream infections. However, this practice affects the gut microbiome and potentially increases dysbiosis, which is closely related to transplantation outcomes, and lower gastrointestinal (GI) tract acute graft-versus-host disease (GVHD). This study assessed the impact of omitting ciprofloxacin prophylaxis on GI GVHD, clinical outcomes, and microbiome composition in patients undergoing allo-HSCT.

Immune reconstitution inflammatory syndrome (IRIS) in a patient with neuro pulmonary nocardiosis following hematopoietic cells transplantation (HCT).

Immune reconstitution inflammatory syndrome (IRIS) is increasingly reported in various HIV negative patients with immunosuppression, but the relationship with hematopoietic cell transplantation (HCT) is not well defined. We report a case of IRIS in a patient infected with pulmonary and CNS Nocardiosis following HCT due to primary myelofibrosis.

Multidrug-resistant, gram-negative infections in high-risk haematologic patients: an update on epidemiology, diagnosis and treatment.

Purpose Of Review: Multidrug-resistant Gram-negative bacilli (MDR-GNB) infections are a significant cause of morbidity and mortality in high-risk hematologic patients. Early diagnosis and management of antibiotic treatment in these patients is a challenge for physicians. This review focuses on the latest literature reports that concern the epidemiology, diagnosis and treatment of MDR-GNB infections in this population.

Efficacy and safety of isavuconazole compared with voriconazole as primary antifungal prophylaxis in allogeneic hematopoietic cell transplant recipients.

Unlabelled: Voriconazole is frequently discontinued prematurely as primary antifungal prophylaxis (AFP) in allogeneic hematopoietic cell transplant (HCT) recipients due to adverse events. Limited data exists for isavuconazole as AFP. We analyzed adult HCT recipients who received voriconazole or isavuconazole AFP to estimate rate of premature AFP discontinuation, identify risk factors for premature AFP discontinuation, and compare incidence of invasive fungal infection (IFI) and survival at day + 180 post-HCT between patients who received voriconazole/isavuconazole-AFP.

Cytomegalovirus Viral Load Kinetics Predict Cytomegalovirus End-Organ Disease and Mortality After Hematopoietic Cell Transplant.

Background: We investigatedthe association between time-averaged area under the curve (AAUC) of cytomegalovirus (CMV) viral load (VL) by day 100 and overall survival (OS) at 1-year after hematopoietic cell transplantation (HCT).

Methods: In a retrospective cohort study, including patients receiving HCT between June 2010 and December 2017 from Memorial Sloan Kettering Cancer Center, AAUC was calculated for patients with detected VL. Patients were categorized into non-controllers (Q4) and controllers (Q1-Q3) using the highest AAUC quartile as cutoff.

Impact of Preemptive Therapy for Cytomegalovirus on Hospitalizations and Cost after Hematopoietic Stem Cell Transplantation.

Cytomegalovirus (CMV) viremia occurs in 40% to 80% of CMV-seropositive (R+) recipients of allogeneic hematopoietic cell transplantation (HCT). The preemptive therapy (PET) strategy has reduced the risk of CMV end-organ disease (EOD) and associated mortality but may lead to substantial healthcare resource utilization (HCRU) and costs. Real-world data on the economic impact of PET is relevant for the evaluation of alternative strategies for CMV management.

Impact of Preemptive Therapy for Cytomegalovirus on Toxicities after Allogeneic Hematopoietic Cell Transplantation in Clinical Practice: A Retrospective Single-Center Cohort Study.

(Val)ganciclovir (vGCV) or foscarnet (FCN) as preemptive therapy (PET) for cytomegalovirus (CMV) after allogeneic hematopoietic cell transplantation (HCT) is associated with myelosuppression and nephrotoxicity, respectively. We analyzed a cohort of CMV-seropositive (R) HCT recipients managed preemptively at a single center. The objectives of our study were to (1) quantify the frequencies of neutropenia and acute kidney injury (AKI) through day +100 (D100) post-HCT and at PET discontinuation and (2) assess the impact of PET on neutropenia and AKI in multivariate models.

Baseline Chest Computed Tomography as Standard of Care in High-Risk Hematology Patients.

Baseline chest computed tomography (BCT) in high-risk hematology patients allows for the early diagnosis of invasive pulmonary aspergillosis (IPA). The distribution of BCT implementation in hematology departments and impact on outcome is unknown. A web-based questionnaire was designed.

A Single-Center, Open-Label Trial of Isavuconazole Prophylaxis against Invasive Fungal Infection in Patients Undergoing Allogeneic Hematopoietic Cell Transplantation.

Isavuconazole is a broad-spectrum triazole approved for treatment of invasive fungal infections (IFIs). In this open-label, single-arm study, we evaluated isavuconazole for antifungal prophylaxis after allogeneic hematopoietic cell transplantation (HCT). Adult patients admitted for first HCT received micafungin 150 mg i.
