Recovery of cytomegalovirus (CMV)-specific immunity after hematopoietic cell transplantation (HCT) is essential in controlling CMV infection. We hypothesize that mixed donor engraftment as measured by chimerism at day 30 in CMV D(+) HCTs and full chimerism in CMV D(-) HCTs will be predictive of CMV reactivation. Prospectively collected data for 407 CMV R+ HCT recipients transplanted from 2006 to 2014 at the University of Minnesota were retrospectively analyzed.

Background: Heart transplantation has been shown to be a safe and effective intervention for progressive cardiomyopathy from chronic Chagas disease. However, in the presence of the immunosuppression required for heart transplantation, the likelihood of Chagas disease reactivation is significant. Reactivation may cause myocarditis resulting in allograft dysfunction and the rapid onset of congestive heart failure.

Article Synopsis
  • About 75% of cord blood transplant recipients experience reactivation of human herpes virus-6 (HHV-6), and this study explores its potential impact on the relapse of underlying blood cancers.
  • In a study of 152 patients, those without HHV-6 reactivation by day +28 had a significantly lower likelihood of relapse compared to those who did reactivate the virus (7% vs. 26%).
  • The findings suggest that early HHV-6 reactivation can be used to identify patients at different risks for relapse, indicating that the absence of HHV-6 may enhance the effectiveness of the transplant.

Mycotic aneurysms are a fatal manifestation of disseminated fungal infections in immunocompromised hosts. We present a patient with an Aspergillus mycotic aneurysm after hematopoietic cell transplant. Due to CYP2C19 rapid metabolizer phenotype (*1/*17), therapeutic levels of voriconazole were unobtainable.

Strongyloides stercoralis has the potential to cause accelerated autoinfection in immunocompromised hosts. Screening tests for strongyloidiasis may be falsely negative in the setting of immunosuppression. We report a case of Strongyloides hyperinfection syndrome in a patient with human T-lymphotropic virus type 1-associated T-cell leukemia early after hematopoietic stem cell transplant.

Human herpesvirus 6B (HHV-6B) commonly reactivates after umbilical cord blood transplantation (UCBT) and is associated with delayed engraftment, fever, rash, and central nervous system dysfunction. Recently, CD134 (OX40) has been implicated as a potential viral entry receptor. We evaluated CD4CD134/ and CD8CD134/ cells at day 28 after UCBT in 20 subjects with previously documented HHV-6 reactivation and persistent viremia.

Single-center studies have reported an association between early (before day 100) cytomegalovirus (CMV) reactivation and decreased incidence of relapse for acute myeloid leukemia (AML) following allogeneic hematopoietic cell transplantation. To substantiate these preliminary findings, the Center for International Blood and Marrow Transplant Research (CIBMTR) Database was interrogated to analyze the impact of CMV reactivation on hematologic disease relapse in the current era. Data from 9469 patients transplanted with bone marrow or peripheral blood between 2003 and 2010 were analyzed according to 4 disease categories: AML (n = 5310); acute lymphoblastic leukemia (ALL, n = 1883); chronic myeloid leukemia (CML, n = 1079); and myelodysplastic syndrome (MDS, n = 1197).

Background. De novo and donor-derived invasive fungal infections (IFIs) contribute to morbidity and mortality in solid organ transplant (SOT) recipients. Reporting of donor-derived IFIs (DDIFIs) to the Organ Procurement Transplant Network has been mandated since 2005.

Background: Factitious fever is extremely challenging to diagnose in patients with complicated chronic medical problems, and represents as much as 10% of fevers of unknown origin. Factitious fever caused by self-injecting oral medications through indwelling central catheters is a diagnostic challenge.

Case Presentation: We present a 32-year-old Caucasian female with history of short gut syndrome, malnutrition requiring total parental nutrition, and pancreatic auto-islet transplant with fever of unknown origin.

Background: Lachancea fermentati is an environmental yeast that is also used in the fermentation of alcoholic drinks. It has not previously been described as a human pathogen although the closely related yeast, Saccharomyces boulardii, can cause fungemia. Here we report a case of L.

Background: Persistent neutrophilic meningitis is an unusual form of chronic meningitis that is defined as clinical meningitis with a neutrophilic pleocytosis that persists for greater than 7 days despite empiric antimicrobial therapy. Although numerous disease processes can cause this syndrome, the majority of cases are due to opportunistic pathogens infecting immunocompromised hosts.

Case Presentation: A 47 year-old female presented after basilar skull fracture with persistent neutrophilic meningitis unresponsive to empiric broad-spectrum antibiotics.

Respiratory virus infections, such as influenza A, cause significant morbidity in hematopoietic stem cell transplantation (HSCT) recipients. The clinical characteristics and impact of infection with the novel H1N1 virus in this patient population is not yet well defined, however. HSCT recipients diagnosed with proven or probable H1N1 during the 2009 pandemic were identified and charts were retrospectively reviewed with analysis of clinical descriptions, risk factors, diagnosis, treatments, and outcomes.
