The authors encountered the case of an 8-fold increase in the concentration/dose (C/D) ratio of tacrolimus (TAC) following the coadministration of voriconazole (VRCZ) in a hematopoietic stem cell transplantation (HSCT) recipient. The interaction observed was much greater than expected and the patient had also been treated with oral risperidone (RSP). We hypothesized that cytochrome P450 (CYP)3A inhibition of the small intestine by VRCZ and P-glycoprotein (P-gp) inhibition of the small intestine by RSP exerted a synergistic effect on the bioavailability of TAC...

OBJECTIVE: Patients who receive allogeneic hematopoietic stem cell transplantation may experience oral complications due to chronic graft-versus-host disease (cGVHD). The manifestations may include progressive sclerosis-like changes that may involve various body sites, including the oropharynx. METHODS AND RESULTS: We present two cGVHD cases of oropharyngeal fibrotic changes that affected functions that were treated with photobiomodulation (PBM) therapy. These case reports suggest that PBM therapy represents an additional, innovative approach affecting discrete phases in cGVHD-associated fibrotic changes...

Allogeneic hematopoietic stem cell transplantation (HSCT) is the recommended treatment for children with very high risk acute lymphoblastic leukemia (ALL), but it requires adequate institutional infrastructure, experience, and expertise, especially for alternative donor HSCT. We review our experience with high-dose chemotherapy (HDCT) and autologous peripheral blood stem cell transplantation (APBSCT), followed by post-APBSCT maintenance chemotherapy for children with very high risk ALL. Between August 1997 and November 2012, our institute was not successful with HLA-haploidentical HSCT...

Leukemia relapse remains the major cause of allogeneic hematopoietic stem cell transplantation (HCT) failure and the prognosis for patients with post-HCT relapse is poor. There is compelling evidence that potent selective anti-leukemic effects can be delivered by donor T cells specific for particular minor histocompatibility (H) antigens. Thus, T cell receptors (TCR) isolated from minor H antigen-specific T cells represent an untapped resource for developing targeted T cell immunotherapy to manage post-HCT leukemic relapse...

Coculture of hematopoietic stem cells (HSC) with primary stromal cells from HSC niches supports the maintenance and expansion of HSC and progenitors ex vivo. However, a major drawback is the availability of primary human samples for research and clinical applications. We investigated the use of in vitro derived osteoblasts as a new source of feeder cells and characterized the molecular pathways that mediate their growth promoting activities. First, we compared the growth and differentiation modulating activities of mesenchymal stromal cells (MSC)-derived osteoblasts (M-OST) to that of their undifferentiated precursor on umbilical cord blood (UCB) progenitors...

Background/Aims: Adoptive therapy with regulatory T (Treg) cells to prevent graft-versus-host disease (GVHD) would benefit from a strategy to improve homing to the sites of inflammation following hematopoietic stem cell transplantation (HSCT). Although donor-derived Treg cells have mainly been used in these models, third-party-derived Treg cells are a promising alternative for cell-based immunotherapy, as they can be screened for pathogens and cell activity, and banked for GVHD prevention...

BACKGROUND: Before and after hematopoietic stem cell transplantation (HSCT), most patients suffer from psychophysical limitations due to the treatment. Exercise interventions demonstrate beneficial effects on, for example, strength, endurance, or health-related quality of life during and after HSCT, but with a great variation among patients concerning the response to exercise. This study examines the influence of the initial fitness on the effects of an exercise therapy in pediatric HSCT...

BACKGROUND: The NR4A3 orphan nuclear hormone receptor, NOR1, functions as a constitutively active transcription factor to regulate inflammation, proliferation, and cell survival during pathological vascular remodeling. Inflammatory processes represent key mechanisms leading to abdominal aortic aneurysm (AAA) formation. However, a role of NOR1 in AAA formation has not been investigated previously. METHODS: Inflammatory gene expression was analyzed in bone marrow-derived macrophages isolated from NOR1-deficient mice...

OBJECTIVES: Gastrointestinal graft-versus-host disease (GI-GVHD) is a potentially life-threatening complication after hematopoietic stem cell transplantation. Symptoms indicating GI-GVHD motivates endoscopy with biopsy sampling and histopathological confirmation. However, optimal extent of endoscopy in children is presently unknown. Therefore, we aimed to evaluate if biopsies from the rectosigmoid area versus the rest of the colon/ileocolon with or without biopsies from simultaneous upper endoscopy, were equally reliable for detection of GI-GVHD and relevant differential diagnoses...

REVIEW
Usha R Somaraju, Krishna Tadepalli
BACKGROUND: Gaucher disease is the most common lysosomal storage disorder caused by a deficiency of the enzyme glucocerebrosidase. Current treatment of the disease involves a choice from enzyme replacement therapy, substrate reduction therapy and hemotopoietic stem cell transplantation (HSCT). HSCT is a high risk procedure with possible long-term benefits in the regression of skeletal and neurological changes in people with Gaucher disease. This is an update of a previously published Cochrane Review...

Idiopathic pneumonia syndrome (IPS) is a common, often fatal, complication following hematopoietic stem cell transplantation (HSCT) characterized by severe pneumonitis and interstitial fibrosis. Fully reconstituted syngeneic bone marrow transplant (BMT) mice infected with murine γ-herpesvirus-68 develop interleukin-17 (IL-17)-driven pneumonitis and fibrosis, which mimics clinical manifestations of IPS. We found CD103+ and CD11b+ dendritic cells (DCs) are selectively deficient for the Notch ligand, DLL4, following BMT and CD4+ T cells isolated from lungs and spleens of infected BMT mice display Notch signaling defects...
