Digestive graft versus host disease (GVHD) is a frequent complication after bone marrow transplantation (BMT), but small bowel obstruction is an extremely rare event. We present herein the first pediatric series of 4 cases of small bowel obstruction after BMT with detailed gross, histological data and their genetic status of the NOD2 gene. All patients had a history of severe acute GVHD treated by immunosuppressive agents and/or infliximab (in 3 cases). Acute or progressively worsening abdominal pain accompanied by small bowel occlusion occurred 5-16months after graft and CT-scan revealed multiple small intestinal stenosis...

Annually, it is estimated that approximately 150-200 children aged 0-16 years are diagnosed with acute myeloid leukemia (AML). In Japan, clinical studies with ANLL91, AML99, CCLSG-AML9805, and JPLSG-AML05 protocols were performed historically, and the risk stratification with a combination of chemotherapy and hematopoietic stem cell transplantation resulted in the improvement of clinical outcomes. Regarding the onset of pediatric AML at the molecular level, mutations in FLT3-ITD or KIT (Class I mutation) showed a poor prognosis, but the ratio of mutations in Class III-V genes was smaller than that in adult AML...

BACKGROUND: Allogeneic hematopoietic cell transplantation (HCT) cures many patients, but often with the risk of late effects and impaired quality of life. The value of quantifying patient-reported outcomes (PROs) is increasingly being recognized, but the routine collection of PROs is uncommon. This study evaluated the feasibility of prospective PRO collection by an outcome registry at multiple time points from unselected HCT patients undergoing transplantation at centers contributing clinical data to the Center for International Blood and Marrow Transplant Research (CIBMTR), and then it correlated the PRO data with clinical and demographic data...

High-risk, recurrent, or refractory solid tumors in pediatric, adolescent, and young adult (AYA) patients have an extremely poor prognosis despite current intensive treatment regimens. We piloted an allogeneic bone marrow transplant platform using reduced-intensity conditioning (RIC) and partially HLA-mismatched (haploidentical) related donors for this population of pediatric and AYA solid tumor patients. Sixteen patients received fludarabine, cyclophosphamide, melphalan, and low-dose total body irradiation RIC haploidentical BMT (haploBMT) followed by post-transplantation cyclophosphamide (PTCy), mycophenolate mofetil, and sirolimus...

Cord blood transplantation (CBT) from HLA-identical siblings is an attractive option for patients with bone marrow failure (BMF) syndrome because of the low risk of graft-versus-host disease (GVHD) and the absence of risk to the donor. We analyzed outcomes of 117 patients with inherited or acquired BMF syndrome who received CBT from a related HLA-identical donor in European Group for Blood and Marrow Transplantation centers between 1988 and 2014. Ninety-seven patients had inherited and 20 patients acquired BMF syndrome...

To improve survival in young children with malignant brain tumors, irradiation-avoiding or -minimizing marrow-ablative chemotherapy (HDCx) with autologous hematopoietic cell transplantation (AuHCT) has been investigated. We evaluated the outcome of 44 children with malignant brain tumors treated with HDCx and tandem AuHCT at Children's Hospital Los Angeles between June 1999 and July 2012. Forty-four children with malignant brain tumors were studied. Twenty-one had medulloblastoma/primitive neuro-ectodermal tumor, eight atypical teratoid/rhabdoid tumor (ATRT), five high-grade glioma, four malignant germ cell tumor, three ependymoma and three choroid plexus carcinoma...

BACKGROUND: The combination of fludarabine (Flu), high dose cytarabine (Ara-C) and granulocyte-colony stimulating factor (G-CSF) called "FLAG" with anthracyclines has become a standard chemotherapy for refractory acute myeloid leukemia (AML) in European children and adults. To clarify the efficacy and the safety of FLAG-idarubicin (IDA) for children prospectively, we planned a multicenter phase II study (AML-R11) by Japanese Pediatric Leukemia/Lymphoma Study Group. METHODS: Patients with AML at the age between 2 and 20 years old, who had the first bone marrow (BM) relapse or induction failure, were enrolled...

The advances in hematopoietic cell transplantation (HCT) over the last decade have led to a transplant-related mortality below 15%. Hepatic sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) is a life-threatening complication of HCT that belongs to a group of diseases increasingly identified as transplant-related, systemic endothelial diseases. In most cases, SOS/VOD resolves within weeks; however, severe SOS/VOD results in multi-organ dysfunction/failure with a mortality rate >80%. A timely diagnosis of SOS/VOD is of critical importance, given the availability of therapeutic options with favorable tolerability...

The experience using anidulafungin for the treatment of invasive fungal infections in pediatrics is limited. In this article, we describe our experience in 55 children. Anidulafungin was administered intravenously at a loading dose of 3 mg/kg once daily, followed by 1.5 mg/kg every 24 hours over a mean period of 14 days (range: 7-22 days). Patients' median age was 114 months old (interquartile range: 32-168 months old). All patients had underlying diseases. Among patients with bone marrow transplant, the difference in white blood cell count, transaminase levels, and renal function at baseline and at the end of anidulafungin administration was not significant...

There are only a few reports of successful use of mammalian target of rapamycin (mTORI) as primary immunosuppression in pediatric heart transplantation. Compared to calcineurin inhibitors, mTORI have less side effects, especially nephrotoxicity, infections, and malignancies. A retrospective study was conducted at our institution of all 170 heart transplants from 1995 to 2015. Nineteen patients were switched from tacrolimus (n=15) or cyclosporin (n=4) to everolimus (n=4) or sirolimus (n=15) due to nephrotoxicity (n=5), malignancy (n=8), EBV viremia/reactive plasmacytic changes (n=5), and immune hemolytic anemia (n=1)...

BACKGROUND: Aplastic anemia is a bone marrow failure syndrome with high mortality affecting children and young adults. Although current treatment guidelines recommend hematopoietic stem cell transplant (HCT) for patients with matched sibling donors, outcomes with alternate donor options have been improving. PROCEDURE: We analyzed a validated multiinstitutional pediatric cohort using one of the largest pediatric and young adult database, the Pediatric Health Information System, for patients diagnosed with aplastic anemia (AA) from 2006 to 2015...

High-dose etoposide phosphate, a water-soluble prodrug of etoposide, may be used after total body irradiation (TBI) in pediatric allogeneic bone marrow transplantation for lymphoblastic leukemia. In a retrospective study of 21 children treated at the Nancy University Hospital (2000-2014), we identified unprecedentedly an unexpectedly high incidence (57%) of acute renal injury following etoposide phosphate infusion. Patients who developed renal function impairment experienced more severe mucositis but had outcomes similar to those who did not...

Although BMT is lifesaving in many childhood diseases, it was found to be related to anxiety, depression, and PTSD in parents, and PTSD, anxiety and overall low self-esteem in siblings. Research on siblings' HRQoL is limited. The aim of this study was to investigate PTSD and HRQoL in siblings (donor and non-donor) of pediatric BMT survivors and PTSD in their mothers, compared to the healthy controls. Thirty-five siblings and their mothers and 35 healthy peers and their mothers were recruited as the study group and as the comparison group, respectively...

Human hematopoiesis is a complex and dynamic system where morphologically and functionally diverse mature cell types are generated and maintained throughout life by bone marrow (BM) Hematopoietic Stem/Progenitor Cells (HSPC). Congenital and acquired hematopoietic disorders are often diagnosed through the detection of aberrant frequency or composition of hematopoietic cell populations. We here describe a novel protocol, called "Whole Blood Dissection" (WBD), capable of analyzing in a single test-tube, hematopoietic progenitors and all major mature cell lineages composing either BM or peripheral blood (PB) through a multiparametric flow-cytometry analysis...

Purpose Early thymic precursor (ETP) acute lymphoblastic leukemia (ALL) is an immunophenotypically defined subgroup of T-cell ALL (T-ALL) associated with high rates of intrinsic treatment resistance. Studies in children have shown that the negative prognostic impact of chemotherapy resistance is abrogated by the implementation of early response-based intensification strategies. Comparable data in adults are lacking. Patients and Methods We performed comprehensive clinicobiologic, genetic, and survival analyses of a large cohort of 213 adult patients with T-ALL, including 47 patients with ETP-ALL, treated in the GRAALL (Group for Research on Adult Acute Lymphoblastic Leukemia) -2003 and -2005 studies...

Respiratory syncytial virus (RSV) infection can cause lower respiratory tract disease and mortality in pediatric hematopoietic stem cell transplant (HSCT) recipients. We report two children who underwent HSCT and developed RSV infection simultaneously at the Bone Marrow Transplant Unit. The treatment with intravenous palivizumab was provided and sequential viral loads were measured in nasopharyngeal (NP) and whole blood samples. To our knowledge, this is the first report where RSV loads were measured in parallel (NP and blood), before and after palivizumab, in correlation with a favorable clinical outcome in both cases...

The Trichosporon species are yeast-like opportunistic pathogens in immunocompromised patients. Trichosporon asahii infections have been reported in pediatric bone marrow transplant (BMT) patients. However, its incidence is low in the adult literature. A 52-year-old Chinese woman who was diagnosed with acute myeloid leukemia received induction chemotherapy and underwent allogenic bone marrow transplant, which was complicated by a relapse and required salvage chemotherapy. She developed persistent non-neutropenic fever secondary to presumed hepatosplenic candidiasis...
