Survival rates in subsets of pediatric patients who have acute myeloid leukemia (AML) with favorable risk features are now greater than 90%. However, outcomes for patients with high-risk (HR) features remain unacceptably poor. As novel technologies for the identification of HR biomarkers and the detection of residual disease are developed, risk stratification and the application of allogeneic hematopoietic stem cell transplant (HSCT) are evolving. HSCT has been shown to benefit subpopulations of pediatric patients with AML, including those with HR cytogenetic translocations, genetic mutations, and/or residual disease after induction...

We assessed the clinical outcomes of allogeneic hematopoietic stem cell transplantation (SCT) from alternative donors for pediatric patients with hematological malignancies, defining graft-versus-host disease (GVHD)-free, relapse-free survival (GRFS) as a composite endpoint. We also defined chronic GVHD-free, relapse-free survival (cGRFS) as survival without severe chronic GVHD, relapse, or death. The probabilities of 2-year disease-free survival from a human leukocyte antigen (HLA) matched unrelated donor (n = 57), related donor with HLA-1 antigen mismatch in the graft-versus-host direction (1Ag-GvH-MMRD, n = 28), and unrelated umbilical cord blood (n = 35) were 52...

: 112 Background: The benefits of early integration of palliative care (PC) in oncology have been well established yet, there remain significant barriers to PC integration, especially in the setting of pediatric hematopoietic stem cell transplant (HSCT). HSCT patients are prone to a great degree of treatment related toxicity and are at high risk for morbidity and mortality and, while ideally suited to benefit, inherent factors in this cure oriented field preclude the integration of PC services...

Sinusoidal obstructive syndrome (SOS) is a potentially fatal form of hepatic injury following hematopoietic stem cell transplant (HSCT). Patients can develop liver dysfunction, portal hypertension, ascites, coagulopathies, and multi-system organ failure. The mortality rate of severe SOS has been reported as high as 98% by Day 100 post-transplant. Defibrotide, which is now approved for the treatment of SOS, has significantly decreased mortality. Defibrotide is a polynucleotide with pro-fibrinolytic, anti-ischemic, and anti-inflammatory activity...

Chemotherapy and irradiation can affect the gonads, leading to impairment of pubertal development and/or infertility. Fertility preservation (FP) is therefore a crucial endeavor in hematopoietic stem cell transplantation (HSCT) because of the severe impact of infertility on the quality of life of long-term survivors. Despite the existence of different international guidelines, FP counseling and procedures are not routinely implemented as part of patient care. We present herein a survey conducted by the Pediatric Working Party of the European Society for Blood and Marrow Transplantation (EBMT), which aims to analyze and compare different FP practices for children and adolescents across EBMT centers in 2013...

BACKGROUND: More than 85% of children affected by acute lymphoblastic leukemia (ALL) are successfully treated; however relapse remains a remarkable clinical concern, with 50-60% of relapsing patients facing a fatal outcome. Management of relapsed patients includes standardized intensive risk-adapted regimens based on conventional drugs, and hematopoietic stem cells transplantation for patients with unfavourable features. Biological drugs, in particular the monoclonal antibody epratuzumab and the bi-functional recombinant single chain peptide blinatumomab, have been recently recognized as novel potential agents to be integrated in salvage ALL therapy to further improve rescue outcome...

Adherence to oral medications has been repeatedly shown to fall below the recommended 80% to 95% in pediatric and adult cancer populations. The purpose of this review is to report the state of the science about oral medication adherence during the acute phase of hematopoietic stem cell transplantation across the lifespan. An exhaustive search of the literature yielded 5 records for inclusion in the review. Two studies examined adherence in pediatrics, 2 in adults, and 1 included both pediatric and adult patients...

Severe combined immunodeficiency (SCID) is 1 of the most common indications for pediatric hematopoietic cell transplantation (HCT) in patients with primary immunodeficiency. Historically, SCID was diagnosed in infants who presented with opportunistic infections within the first year of life. With newborn screening (NBS) for SCID in most of the United States, the majority of infants with SCID are now diagnosed and treated in the first 3.5 months of life; however, in the rest of the world, the lack of NBS means that most infants with SCID still present with infections...

Sustained donor engraftment after allogeneic hematopoietic cell transplantation (HCT) converts to healthy donor hemoglobin synthesis and halts disease symptoms in patients with sickle cell disease and thalassemia major. A disease-free survival probability that exceeds 90% has been reported when HCT using an HLA-matched sibling donor is performed in young patients with low-risk disease or treatment-related risk factors. Alternate donor HCT and HCT in adults is performed infrequently because of a higher risk profile...

Cytomegalovirus (CMV) is a frequent complication of hematopoietic stem cell transplant in pediatric patients, with significant morbidity and mortality. Antiviral drugs are used as prophylactic, preemptive or therapeutic medicines; however, no uniform guidelines exist for the best strategy to prevent CMV disease. Resistance to standard antiviral therapies can lead to further difficulty in managing CMV disease. Studies for investigational therapies are underway and could provide options for treatment of resistant CMV, while limiting toxicities associated with currently used antiviral therapies...

BACKGROUND: The diagnostic yield of bronchoalveolar lavage (BAL) in the Immunocompromised pediatric population has ranged from 28% to 68%. We hypothesized that the diagnostic yield of BALs would be higher in more recent years due to new diagnostic assays. METHODS: A retrospective case series was performed among immunocompromised children ≤18 years old who underwent BALs from 2001 to 2012, to assess the yield of microbiologic diagnostic studies and to determine the impact of BAL findings on antimicrobial management...

Metabolic syndrome (MetS) is a known complication after hematopoietic stem cell transplantations (HSCT) that contributes to long-term morbidity. We assessed the prevalence of components of the MetS in pediatric survivors of allogeneic HSCT and identified associated risk factors. Thirty-eight patients, median age at HSCT, 8.5 years, were evaluated at a median of 3.9 years post-HSCT. Overweight or obesity was seen in 23.7% of the patients, 15.8% had hypertension, 15.8% had hypertriglyceridemia, and 13% had low high-density lipoprotein cholesterol levels according to age and gender...
