An educational symposium for patients with sickle cell disease and their families: results from surveys of knowledge and factors influencing decisions about hematopoietic stem cell transplant.

Background: The only available cure for sickle cell disease (SCD) is hematopoietic stem cell transplant (HSCT). One important barrier to HSCT in SCD is lack of patient and family knowledge.

Procedure: To improve awareness of HSCT as a curative option for SCD, we hosted half-day educational symposia in 2011 and 2012.

Unrelated donor cord blood transplantation for children with severe sickle cell disease: results of one cohort from the phase II study from the Blood and Marrow Transplant Clinical Trials Network (BMT CTN).

The Sickle Cell Unrelated Donor Transplant Trial (SCURT trial) of the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) is a phase II study of the toxicity and efficacy of unrelated donor hematopoietic cell transplantation in children with severe sickle cell disease (SCD) using a reduced-intensity conditioning regimen. Here we report the results for the cord blood cohort of this trial. Eight children with severe SCD underwent unrelated donor cord blood transplantation (CBT) following alemtuzumab, fludarabine, and melphalan.

Risk factors for molecular detection of adenovirus in pediatric hematopoietic stem cell transplantation recipients.

Adenovirus (AdV) infections are a major cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). To evaluate the use of molecular AdV testing in HSCT at our institution and identify risk factors for AdV viremia and disease, we performed a retrospective cohort study of all HSCT recipients who had undergone AdV polymerase chain reaction testing over a 2-year period. Two cohorts were identified: cohort 1, comprising patients testing positive for AdV (n = 7) and cohort 2, comprising patients testing negative (n = 36).

Safety and efficacy of CMX001 as salvage therapy for severe adenovirus infections in immunocompromised patients.

No therapeutic agent has yet been established as the definitive therapy for adenovirus infections. We describe the clinical experience of 13 immunocompromised patients who received CMX001 (hexadecyloxypropyl cidofovir), an orally bioavailable lipid conjugate of cidofovir, for adenovirus disease. We retrospectively analyzed 13 patients with adenovirus disease and viremia treated with CMX001; data were available for ≥ 4 weeks after initiation of CMX001 therapy.

Amelioration of oral mucositis pain by NASA near-infrared light-emitting diodes in bone marrow transplant patients.

Purpose: This study seeks to investigate the use of extra-orally applied near-infrared phototherapy for the reduction of oral pain secondary to chemotherapy- and radiation therapy-induced mucositis in adult and pediatric hematopoietic stem cell transplant (HSCT) patients.

Methods: Eighty HSCT patients were divided into regular (R) and low (L) risk groups, then to experimental (E) and placebo (P) groups, resulting in four groups (ER, EL, PR, PL). Experimental subjects received 670 (± 10) nm gallium-aluminum-arsinide light-emitting diode device for 80 s at ~50 mW/cm(2) energy density and power exposure of 4 J/cm(2).

CD34⁺ collection efficiency as a function of blood volumes processed in pediatric autologous peripheral blood stem cell collection.

Purpose: To characterize the relationship between CD34(+) collection efficiency and blood volumes processed in pediatric patients undergoing autologous peripheral blood stem cell (PBSC) collection.

Methods: Retrospective 8-year (2001-2009) study of pediatric patients (n = 79) with neuroblastoma and central nervous system (CNS) tumors undergoing first day of autologous PBSC harvest using MNC program on the COBE Spectra (Caridian BCT, Lakewood, CO) was performed. Patients undergoing 0 to 2.

Eradication of disseminated adenovirus infection in a pediatric hematopoietic stem cell transplantation recipient using the novel antiviral agent CMX001.

Adenovirus infection is a serious and often fatal complication in hematopoietic stem cell transplant patients. There are currently no FDA-approved therapies for adenovirus infection, with only anecdotal, off-label uses described for a variety of anti-viral agents or immune therapies. We report the first case of successful eradication of disseminated adenovirus infection by the novel antiviral agent CMX001 in a severely immunocompromised pediatric stem cell transplant recipient following failure to respond to intravenous cidofovir.

The burden of cure: long-term side effects following hematopoietic stem cell transplantation (HSCT) in children.

Children who survive hematopoietic stem cell transplantation (HSCT) are at risk for an inordinate number of long-term side effects. Late effects can be secondary to the underlying diagnosis for which the transplant is performed, prior treatment of the disease, the transplant preparative regimen, treatment of the complications of transplant, and immunologic interactions between the graft and the host. This article describes the risks and manifestations of the most commonly reported late effects in survivors of pediatric HSCT.

Safety and efficacy of gemtuzumab ozogamicin in pediatric patients with advanced CD33+ acute myeloid leukemia.

This open-label, dose-escalation study evaluated the safety and efficacy of single-agent gemtuzumab ozogamicin, a humanized anti-CD33 antibody-targeted chemotherapeutic agent, for pediatric patients with multiple relapsed or primary refractory acute myeloid leukemia (AML). Twenty-nine children 1 to 16 years of age (relapsed disease, 19; refractory disease, 10) received gemtuzumab ozogamicin ranging from 6 to 9 mg/m2 per dose for 2 doses (separated by 2 weeks) infused over 2 hours. All patients had anticipated myelosuppression.
