Gastric carcinoid tumor is rarely diagnosed in children. We report a case of gastric carcinoid tumor that occurred after allogeneic HSCT. A 13-year-old girl with ETP acute lymphoblastic leukemia underwent allogeneic HSCT from a 7/8 HLA-matched unrelated donor. She presented with rashes, abdominal pain, and diarrhea, which were suggestive of GVHD, 7 months after HSCT. Immunosuppressive agents failed to resolve these symptoms well. After a series of evaluations, carcinoid syndrome caused by a gastric carcinoid tumor was diagnosed...

OBJECTIVE: Chronic myeloid leukemia (CML) is relatively rare malignancy in childhood. There are limited studies of use of Imatinib Mesylate (IM) alone in management of CML in this age group. METHOD: We retrospectively analyzed the outcome of 30 consecutive children with CML chronic phase treated with IM alone. RESULTS: The median age at the time of diagnosis was 11 years with male preponderance. Asthenia and abdominal discomfort due to splenomegaly were the most common presenting features and splenomegaly a dominant sign...

Two papers were selected for this commentary. The first paper (Citation 1) suggests that a 10-week, moderate-intensity exercise program performed early after allogeneic hematopoietic stem cell transplantation is feasible in this fragile population, and might improve cell cytotoxicity by redistributing subpopulations of NK cells. This study adds to the growing evidence that enhancing immune cell surveillance (e.g., NK cells) in response to exercise could benefit cancer patients. The second paper (Citation 2) studied neutrophil-related mediators of oxidative stress and inflammatory cytokines in response to exercise in children compared with adults...

This study report clinical course, etiology, management, and long-term outcome of children who developed toxic epidermal necrolysis-like reaction (TEN-LR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We retrospectively collected children with TEN-LR occurring after allo-HSCT performed in 2 pediatric bone marrow units between 2005 and 2014. We identified 6 cases of TEN-LR of 322 patients (1.8%). Possible triggers of TEN included antibiotics, antiepileptics, antimycotics, and Mycoplasma infection...

Natural killer (NK) cells play an important role following allogeneic hematopoietic stem cell transplantation (HSCT) exerting graft-versus-leukemia/tumor effect and mediating pathogen-specific immunity. Although NK cells are the first donor-derived lymphocytes reconstituting post-HSCT, their distribution of CD56(++)CD16(-) (CD56(bright)), CD56(++)CD16(+) (CD56(intermediate=int)), and CD56(+)CD16(++) (CD56(dim)) NK cells is explicitly divergent from healthy adults, but to some extent comparable to the NK cell development in early childhood...

Cytomegalovirus (CMV) is a well-established cause of morbidity and mortality in pediatric recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT). CD8⁺ T-cells are important for controlling CMV infection. We conducted a prospective pilot study to investigate the clinical utility of measuring the CMV-specific T-cell immune response using the QuantiFERON-CMV assay (QF-CMV) in pediatric allo-HSCT recipients. Overall, 16 of 25 (64%) patients developed CMV infection. QF-CMV was evaluated in these 16 patients during the early and late phases of the first CMV infection post allo-HSCT...

We report outcomes for 44 children who underwent stem cell transplantation (SCT) for refractory AML in the UK between 2000 and 2012. Median age at SCT was 11.5 years. Twenty-three patients had primary refractory and 21 relapsed refractory AML. Refractory disease was confirmed by cytogenetics/molecular genetics in 24 cases. Median follow-up of the whole cohort is 6.8 years (2.1-14.9 years). Thirty patients (68%) achieved a CR following SCT. Transplant-related mortality at 1 year was 18%. Acute GVHD incidence was 52% (grade ⩾III 19%), chronic 7%...

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...

Dimethyl sulfoxide (DMSO) is a cryoprotective agent used in storage of frozen stem cells in stem cell transplantation. Central nervous system side effects of DMSO such as epileptic seizures, stroke, transient global amnesia, and temporary leucoencephalopathy are rarely seen. Here, we report a pediatric patient who developed seizures after DMSO-cryopreserved stem cell infusion and whose magnetic resonance imaging of the brain demonstrated parietal and occipital focal cortical T2-signal intensity increase. DMSO toxicity should be kept in mind in patients who received cryopreserved stem cell infusion and magnetic resonance imaging may be helpful in differential diagnosis of central nervous system involvement...

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...

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...

BACKGROUND: Etoposide (VP-16), a podophyllotoxin derivative, is used in conditioning regimens before allogeneic hematopoietic stem cell transplantation in children with acute lymphoblastic leukemia. The aim of this study was to develop a limited sampling strategy (LSS) suitable for the prediction of exposure to VP-16 defined as area under time-concentration curve (AUC). METHODS: The study included 28 pediatric patients with acute lymphoblastic leukemia, who were administered a 4-hour infusion of 60 mg/kg VP-16...

REVIEW
Ibrahim T Aldoss, Guido Marcucci, Vinod Pullarkat
Although pediatric acute lymphoblastic leukemia (ALL) has cure rates of over 90%, adult ALL remains a challenging disease to treat, with cure rates roughly half those seen in children. The inferior outcomes in adults can be attributed mainly to adverse genetic features, as well as the inability-particularly of older adults-to tolerate chemotherapy. Modest improvements have been seen in outcomes for adolescents and young adults; these can largely be attributed to the use of pediatric-type combination chemotherapy regimens in patients aged 50 years or younger...

STAT4 polymorphism, rs7574865 is linked to various autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Its T minor allele is associated with higher STAT4 mRNA and protein expression, indicating a stronger skewed immune response than the norm. Although widely studied in autoimmune disease patients and the general population, its effect on immunocompromised subjects is still unknown. Especially in situations, i.e. post-hematopoietic stem cell transplantation (post-HSCT), where control of the immune response is crucial...
