BACKGROUND: Absent T cell immunity resulting in life-threatening infections provides a clear rationale for hematopoetic stem cell transplantation (HSCT) in patients with severe combined immunodeficiency (SCID). Combined immunodeficiencies (CID) and "atypical" SCID show reduced, not absent T-cell immunity. If associated with infections or autoimmunity, they represent profound CID (P-CID), for which outcome data are insufficient for unambiguous early transplant decisions. OBJECTIVES: We recruit non-transplanted P-CID patients aged 1-16 years to compare natural histories of severity-matched patients with/without subsequent transplantation and to determine whether immunological and/or clinical parameters may be predictive for outcome...

Hematopoetic stem cell transplantation (HSCT) is an established therapeutic option for both malignant and nonmalignant indications, whose incidence has continued to increase in recent years. Because of its lower cost and lack of radiation exposure, ultrasound examination is often the first-line imaging modality in evaluating patients both before and after HSCT. It is important for radiologists to be aware of sonographic manifestations of the complications that may arise from HSCT. In this study, we will review the basics of HSCT, the role of imaging, and ultrasound examination findings in common and uncommon complications arising from HSCT...

Immunosuppression of various origins is associated with an increased risk of infection; therefore the prevention of infectious diseases by vaccination is especially important in immunocompromised patients. However, the response to vaccinations is often reduced in these risk groups and the application of live vaccines is contraindicated during immunosuppression.In the following expert statement, recommendations for vaccination were created on the basis of current evidence and theoretical/immunological considerations...

Total 26 children of thalassemia underwent hematopoetic stem cell transplantation from September 2006 to December 2014. Out of these 17 were matched sibling transplantation (MST) and 9 were unrelated umbilical cord blood transplantation (UCT). Median age was 4 years. At a median follow up of 46.5 months, 12 of 17 (70 %) MST and 3 out of 9 (33.33 %) UCT were cured of thalassemia. Three (11.53 %) patients died due to transplant related mortality. Average cost of MST was 6 lakhs and that of UCT was 20 lakhs...

OBJECTIVE: A novel approach to regulate obesity-associated adipose inflammation may be through metabolic reprogramming of macrophages (MΦs). Broadly speaking, MΦs dependent on glucose are pro-inflammatory, classically activated MΦs (CAM), which contribute to adipose inflammation and insulin resistance. In contrast, MΦs that primarily metabolize fatty acids are alternatively activated MΦs (AAM) and maintain tissue insulin sensitivity. In actuality, there is much flexibility and overlap in the CAM-AAM spectrum in vivo dependent upon various stimuli in the microenvironment...

Intravenous (IV) busulfan doses are often personalized to a concentration at steady state (Css) using the patient's clearance, which is estimated with therapeutic drug monitoring. We sought to identify biomarkers of IV busulfan clearance using a targeted pharmacometabonomics approach. A total of 200 metabolites were quantitated in 106 plasma samples, each obtained before IV busulfan administration in hematopoietic cell transplant (HCT) recipients. Both univariate linear regression with false discovery rate (FDR) and pathway enrichment analyses using the Global test were performed...

The importance of proinflamatory cytokines and acute phase proteins in pathogenesis and progression of MM is well known. However, there are any studies evaluating the role of NT-proCN in management and treatment of MM. The aim of our study was to evaluate the concentration of NT-proCNP and acute phase proteins in patients with MM before and after stem cell transplantation. We involved 40 newly diagnosed MM patients in stage III according to the Durie-Salmon classification and treated with high dose of melphalan (200mg/m2) prior to ASCT...

Sfrp2 is overexpressed in stromal cells which maintain hematopoietic stem cells (HSCs) during in vitro culture. We here showed, that coculture of hematopoetic cells with stromal cells with reduced expression of Sfrp2 increases the number lineage-negative Kit(+) Sca-1(+) (LSK) and progenitor cells in vitro. The LSK cells from these cocultures showed activation of canonical Wnt signaling, higher levels of Ki-67, BrdU incorporation, and the number of γH2A.X positive foci. Total repopulating activity of these cultures was, however, diminished, indicating loss of HSC...

Evidence is accumulating that extracellular microvesicles (MV) facilitate progression and relapse in cancer. Using a model in which MVs derived from K562 chronic myelogenous leukemia (CML) cells transform normal hematopoietic transplants into leukemia-like cells, we defined the underlying mechanisms of this process through gene-expression studies and network analyses of transcription factors (TF) and miRNAs. We found that antitumor miRNAs were increased and several defense pathways were initiated during the early phases of oncogenic transformation...

Cyclosporine-induced sebaceous hyperplasia (SH) is a well-documented entity, occurring in up to 30% of renal transplant patients treated with cyclosporine and has also been reported to occur following heart or hematopoetic stem cell transplantation (HCST). Cyclosporine has a stimulatory effect on undifferentiated sebocytes, resulting in the clinical and histologic findings in these patients. Sebaceous hyperplasia most commonly presents as asymptomatic papules over the face, chest, or groin. Herein we describe a case of a 27-year-old man who developed facial sebaceous hyperplasia five months after completing cyclosporine therapy for cutaneous graft versus host disease (GVHD) following HSCT...

OBJECTIVE: Providing care to one's child during and after a hematopoietic stem cell transplant (HSCT) is a universally stressful experience, but few psychological interventions have been developed to reduce caregiver distress. The goal of this study was to test the efficacy of a brief cognitive-behavioral intervention delivered to primary caregivers. METHOD: Two hundred eighteen caregivers were assigned either best-practice psychosocial care (BPC) or a parent social-cognitive intervention program (P-SCIP)...

BACKGROUND: BK polyomavirus (BKPyV) can cause hemorrhagic cystitis (HC) in allogeneic hematopoietic stem cell transplant (allo-HSCT) patients and polyomavirus-associated nephritis in renal transplant patients, while JC polyomavirus (JCPyV) can generate progressive multifocal leukoencephalopathy in immunocompromised individuals. Since 2007, additional human polyomaviruses (HPyVs) have been identified. In this study, we examined the urines of allo-HSCT patients for possible presence of polyomaviruses BKPyV, JCPyV, KIPyV, WUPyV, MCPyV, HPyV6, HPyV7, TSPyV, HPyV9, and HPyV10 (MWPyV)...

Understanding how our T-cell compartments are maintained requires knowledge of their population dynamics, which are typically quantified over days to weeks using the administration of labels incorporated into the DNA of dividing cells. These studies present snapshots of homeostatic dynamics and have suggested that lymphocyte populations are heterogeneous with respect to rates of division and/or death, although resolving the details of such heterogeneity is problematic. Here we present a method of studying the population dynamics of T cells in mice over timescales of months to years that reveals heterogeneity in rates of division and death with respect to the age of the host at the time of thymic export...

Hematopoetic stem cell transplantation (HSCT) improves survival in patients with severe systemic sclerosis (SSc) by resetting the immune system. We studied how HSCT acts on the key SSc skin pathology findings (fibrosis and vascularization). In mean, 3 skin punch biopsies per patient (range 2-6) were analyzed from 13 patients (5 females) with severe diffuse SSc before and up to 96 months after HSCT. Fibrosis of the four skin layers was graded semi-quantitatively and an overall fibrosis score was then calculated...

The development of treatments for Ebola virus disease (EVD) has been hampered by the lack of small-animal models that mimick human disease. Here we show that mice with transplanted human hematopoetic stem cells reproduce features typical of EVD. Infection with Ebola virus was associated with viremia, cell damage, liver steatosis, signs of hemorrhage, and high lethality. Our study provides a small-animal model with human components for the development of EVD therapies.
