BACKGROUND: Diagnosis of engraftment syndrome (ES) following allogeneic hematopoietic stem cell transplantation (HSCT) can be a challenge due to the systemic presentation and alternative etiologies. With a goal of establishing biomarkers to more accurately distinguish ES, we prospectively analyzed levels of cytokines during HSCT. PROCEDURES: We performed a prospective study of children ≤21 years who underwent allogeneic HSCT. Blood samples for interleukin (IL)-6, IL-8, IL-10, IL-1b, IL-12p70, interferon-γ, tumor necrosis factor alpha (TNF-α) and procalcitonin were obtained from each subject prior to conditioning, at day 0, and then biweekly through engraftment and at days 30, 60 and 100...

PURPOSE: Pediatric inflammatory bowel disease (IBD) is a heterogeneous disorder caused by multiple factors. Although genetic and immunological analyses are required for a definitive diagnosis, no reports of a comprehensive genetic study of a Japanese population are available. METHODS: In total, 35 Japanese patients <16 years of age suffering from IBD, including 27 patients aged <6 years with very early-onset IBD, were enrolled in this multicenter study. Exome and targeted gene panel sequencing was performed for all patients...

PURPOSE: The incidence of cytomegalovirus (CMV) retinitis in the pediatric allogeneic hematopoietic stem cell transplant (HSCT) population is unknown. We report a cluster of 5 pediatric patients with CMV retinitis diagnosed in a 12-month period, and compare this to the rate of CMV viremia and retinitis in the four years prior. Presented is the ophthalmic screening protocol developed in response to this experience. DESIGN: Retrospective cross-sectional study. METHODS: A retrospective chart review was performed on patients at Children's Hospital of Colorado (CHCO) who received allogeneic HSCT between January 2010 and December 2014...

CLS involves sudden loss of intravascular fluids into the interstitial spaces. CLS was described as a possible complication after SCT. Few studies report the incidence of CLS in pediatric populations. We aimed to assess CLS incidence, its risk factors, and impact on the survival. The clinical charts of patients <18 years of age transplanted at our institution between 2002 and 2012 were reviewed. CLS was defined by weight gain >3% in 24 hours and positive intake balance despite furosemide administration...

OBJECTIVE: To provide a review of the literature regarding this technique as well as a step-by-step description with the goal of increasing its use as a safe surgical option. Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is characterized by vaginal agenesis and a variety of mullerian duct anomalies. To date, a variety of procedures have been described for creating a neovagina, but the best treatment remains debated. The Wharton-Sheares-George method, a minimally invasive surgical approach for the creation of a neovagina, is remarkably simple to perform...

We describe a single-center prospective study of alemtuzumab as a second-line agent for steroid-refractory (SR) acute graft-versus-host disease (aGVHD) in pediatric and young adult allogeneic hematopoietic stem cell transplant recipients. Alemtuzumab was administered for grades II to IV aGVHD if patients did not improve within 5 days or worsened within 48 hours after corticosteroids. Interim analyses of alemtuzumab levels and response were performed after every 5 patients enrolled, resulting in 3 dosing cohorts, as follows: (1) ...

Data on post-transplant iron overload (IO) are scarce in pediatrics. We conducted a prospective multicenter cohort study (Leucémie de l'Enfant et de l'Adolescent cohort) to determine the prevalence and risk factors of IO in 384 acute leukemia survivors transplanted during childhood. Prevalence of IO (ferritin level ⩾350 ng/mL) was 42.2% (95%CI 37.2-47.2%). Factors significantly associated with IO were: 1) in univariate analysis: older age at transplant (P<0.001), allogeneic versus autologous transplantation (P<0...

We investigated the efficacy of allogeneic hematopoietic stem cell transplantation (alloHSCT) in pediatric patients with mucopolysaccharidosis (MPS). A retrospective analysis of transplantation data from 34 cases of MPS from the China Children Transplant Group, treated between December 2004 and September 2015, was conducted. Among the 34 cases, 12 cases were type I, 12 were type II, 4 were type IV, 4 were type VI, and 2 were of an unknown type. The median age at transplantation was 3.75 years (range, 1 to 7 years); the median follow-up time was 14 months (range, 2 to 119 months)...

Pediatric anaplastic large cell lymphoma (ALCL) is a chemosensitive malignancy, but about 30% of patients experience relapse. In most of these patients, a second complete remission is obtainable with salvage chemotherapy, though relapse free survival rates are as low as 30-60%. Herein, we report a 6-year-old boy with relapsed anaplastic lymphoma kinase (ALK) positive ALCL successfully treated with vinblastine monotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT), with a reduced intensity conditioning (RIC) regimen, from his father...

Maraviroc is an allosteric small molecule antagonist of chemokine receptor type 5 (CCR5) and has been used in adult allogeneic hematopoietic stem cell transplant (HSCT) recipients to prevent acute graft-versus-host disease (GVHD) of the gastrointestinal (GI) tract and liver. The goal of this study was to establish feasibility and pharmacokinetic and pharmacodynamic profiles of maraviroc in pediatric HSCT recipients. Children ages 2 to 12 years were enrolled and maraviroc was added to standard GVHD prophylaxis, which included a calcineurin inhibitor and either steroids or mycophenolate mofetil...

BACKGROUND: Infectious complications are a significant cause of hematopoietic stem cell transplantation (HSCT) failure, especially allogeneic HSCT (allo-HSCT) because of delayed immune reconstitution and graft-versus-host disease (GVHD) occurrence. Identifying the factors responsible for bacterial infections (BI) in patients undergoing HSCT will provide much more effective empirical antimicrobial treatment in this group of patients. OBJECTIVE: The aim of this study was to evaluate the epidemiology and profile of BI in patients after HSCT in 5 centers of the Polish Pediatric Group for Hematopoietic Stem Cell Transplantation in 2012-2013...

BACKGROUND AIMS: In pediatric patients, adenovirus (ADV) reactivation after allogeneic hematopoietic stem cell transplantation (allo HSCT) is a major cause of morbidity and mortality. For patients who do not respond to antiviral drug therapy, a new treatment approach using ADV-specific T cells can present a promising alternative. Here we describe the clinical scale Good Manufacturing Practice (GMP)-compliant manufacture and characterization of 40 ADV-specific T-cell products, Cytovir ADV, which are currently being tested in a multi-center phase I/IIa clinical trial...

X-linked lymphoproliferative disease type 2 (XLP-2, OMIM 300635) is a primary immunodeficiency caused by the loss of X chromosome-linked inhibitor of apoptosis (XIAP), the X-linked inhibitor of apoptosis gene at Xq25. XLP-2 individuals are susceptible to several specific and potentially fatal infections, such as Epstein-Barr virus (EBV). Children with XIAP-related XLP-2 may present with either familial hemophagocytic lymphohistiocytosis, often triggered in response to EBV infection, or with a treatment-refractory severe pediatric form of inflammatory bowel disease (IBD) that might be diagnosed as Crohn disease...
