Delayed engraftment is a major limitation of cord blood transplantation (CBT), due in part to a defect in the cord blood (CB) cells' ability to home to the bone marrow. Because this defect appears related to low levels of fucosylation of cell surface molecules that are responsible for binding to P- and E-selectins constitutively expressed by the marrow(More)
The concept of veno-occlusive disease (VOD), along with our understanding of it, has historically been and remains an evolving phenomenon. This review presents a broad view of VOD, also known as sinusoidal obstruction syndrome (SOS), including (1) traditional hematopoietic stem cell transplant-associated VOD/SOS, (2) late-onset VOD/SOS, (3) pulmonary VOD,(More)
The curative potential of hematopoietic stem cell transplantation in patients with chronic granulomatous disease depends on availability of a suitable donor, successful donor engraftment, and maintenance of long-term donor chimerism. Twelve consecutive children (median age, 59.5 months; range, 8-140 months) with severe chronic granulomatous disease (serious(More)
BACKGROUND Adolescents and young adults (AYAs) are a very unique subset of our population journeying through a dynamic stage of their lives. This age group often remains understudied as a separate entity because they are commonly lumped into either pediatric or adult subgroups. METHODS Here we review acute and chronic issues surrounding hematopoietic stem(More)
The adoptive transfer of pathogen-specific T cells can be used to prevent and treat opportunistic infections such as cytomegalovirus (CMV) infection occurring after allogeneic hematopoietic stem-cell transplantation. Viral-specific T cells from allogeneic donors, including third party donors, can be propagated ex vivo in compliance with current good(More)
Cord blood transplantation is being used with increasing frequency for patients with high-risk hematologic malignancies. Myeloablative preparative regimens provide antitumor efficacy and facilitate engraftment but are associated with higher morbidity and nonrelapse mortality rates than nonablative regimens. We evaluated 3 sequential myeloablative regimens(More)
We assessed clinical practice standards for infectious complications among pediatric blood and marrow transplant (PBMT) recipients. An anonymous online survey was sent to all 64 pediatric program directors (PD) of PBMT centers in the United States, which are accredited by the Foundation for the Accreditation of Cellular Therapy (FACT). The overall response(More)
We conducted a retrospective analysis of outcomes for children and young adults with sAML/sMDS who underwent HSCT at our institution. Thirty-two patients (median age 20 years) with sAML (n=24) and sMDS (n=8) received HSCT between 1990 and 2013. The median time from sAML/sMDS diagnosis to HSCT was 4.1 months (range: 1.2-27.2 months). The transplant regimens(More)
Histologic confirmation is considered a standard practice to diagnose gastrointestinal graft versus host disease (GI GVHD) and is often used in making treatment decisions. A histologic grade is often determined in cases that are diagnosed with GI GVHD. Although extensive crypt loss (histologic grade 4) is associated with high nonrelapse mortality (NRM), the(More)
The use of HSCT is the only potentially curative treatment for CAMT, but access is limited by the availability of suitable donors. We report five consecutive patients with CAMT who received MAC and partially HLA-mismatched, UCBT (unrelated, n = 4). Median times to neutrophil (>500/μL) and platelet (≥20 000 and ≥50 000/μL) engraftment were 19, 57, and 70(More)
