Hematopoietic stem cell transplantation (HSCT) has been accessible to the population residing in Lebanon and surrounding countries since 1997. HSCT programs were developed in two major hospitals in Beirut: American University of Beirut Medical Center (AUBMC) and Makassed General Hospital. Mount Lebanon Hospital initiated an autologous HSCT activity later. Between 2012 and 2016, the HSCT activity in Lebanon reached a total of 897 transplants, among which 303 (33.8%) were allogeneic HSCT and 594 (66.2%) were autologous HSCT...

Allogeneic hematopoietic stem cell transplantation (HSCT) remains the only curative therapy for sickle cell disease (SCD); however, its use is limited by lack of suitable human leukocyte antigen (HLA)-matched donors and decreased application in older patients with significant morbidity. Myeloablative, HLA-identical sibling transplantation in children with SCD offers excellent long-term survival, with overall and event-free survival rates of 95% and 92%, respectively. However, the risk of graft-versus-host-disease, infections, infertility, and other long-term transplant complications, further limits its widespread use...

OBJECTIVE/BACKGROUND: Chemotherapy followed by autologous hematopoietic stem cell transplantation (HSCT) remains the standard treatment for multiple myeloma (MM). Thalidomide or bortezomib may be combined with cyclophosphamide and dexamethasone, in what are known as the CTD and VCD protocols, respectively. The objective of this study was to evaluate the clinical characteristics and response rates obtained with CTD and VCD, observing whether the inclusion of bortezomib to treat MM patients in Brazil increases therapeutic efficiency...

Patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are at increased risk of invasive fungal infections, especially during the early neutropenic phase and severe graft-versus-host disease. Mold-active prophylaxis should be limited to the highest risk groups. Empiric antifungal therapy for HSCT with persistent febrile neutropenia is associated with unacceptable response rates, unnecessary antifungal therapy, increased risk of toxicity, and inflated costs. Empiric therapy should not be a substitute for detailed work up to identify the cause of fever in such patients...

Allogeneic haematopoietic stem cell transplantation (HSCT) from an human leukocyte antigen (HLA)-identical donor can be curative for eligible patients with non-malignant and malignant haematological disorders. HSCT from alternative donor sources, such as HLA-mismatched haploidentical donors, is increasingly considered as a viable therapeutic option for patients lacking HLA-matched donors. Initial attempts at haploidentical HSCT were associated with vigorous bidirectional alloreactivity, leading to unacceptably high rates of graft rejection and graft-versus-host disease (GVHD)...

The ability to inhibit irrelevant information is essential for coping with the demands of everyday life. Inhibitory deficits are present in all stages of dementia and commonly observed in people with Parkinson's disease (PwPD). Inhibition is frequently tested with the Stroop test, but this may lack ecological validity. This study investigates inhibitory control in people with Alzheimer's disease dementia (PwD) and PwPD using the Hayling Sentence Completion Test (HSCT), which aspires to be a more ecologically valid task...

Predicting severe acute GvHD (aGvHD) after allogeneic hematopoietic stem cell transplantation (HSCT) is challenging but critical. Mild aGvHD may have a favorable impact on relapse, whereas severe aGvHD is associated with poor outcomes. The aim of this study was to evaluate whether elevated eosinophil count in the bone marrow (BM) at 1 month after HSCT is associated with a high incidence of new and severe aGvHD. We enrolled 101 consecutive patients; median age was 50 years, and 50.5% patients were male. The median eosinophil concentration in BM at 1 month after HSCT was 1...

Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) infections following allogeneic hematopoietic stem cell transplantation (HSCT) are a major cause of morbidity and mortality. Early clinical trials demonstrate that adoptive transfer of donor-derived virus-specific T cells to restore virus-specific immunity is an effective strategy to control CMV and EBV infection after HSCT, conferring protection in 70%-90% of patients. The field has evolved rapidly to develop solutions to some of the manufacturing challenges identified in early clinical studies, such as prolonged in vitro culture, optimization of the purity of the virus-specific T cell product, the potential limitations of targeting a single viral antigen, and how to manage the patient with a virus-naive donor...

Background: Allogenic hematopoietic stem cell transplantation (HSCT) is a strategy used for treatment of different malignant diseases. However, success of allo-HSCT can be hampered by graft-versus-host-disease (GVHD). Natural killer (NK) cells may play an important role in activating antigen presenting cells and subsequent activation of T cells. The main purpose of this study was the evaluation of IL-21, as a blood biomarker, for early detection of acute GVHD (aGVHD) in children after HSCT and also the study of human leukocytes antigen (HLA)-C1 polymorphism, as a targeting ligand for NK cells in these patients...

Hematopoietic stem cell transplantation (HSCT) using an optimized conditioning regimen is essential for the long-term survival of patients with inherited bone marrow failure syndromes (IBMFS). We report HSCT in 24 children with Fanconi anemia (FA, n = 12), Diamond-Blackfan anemia (DBA, n = 7), and dyskeratosis congenita (DC, n = 5) from a single HSCT center. The graft source was peripheral blood stem cells (n = 19) or cord blood stem cells (n = 5). FA and DC patients received reduced-intensity conditioning, while DBA patients had myeloablative conditioning...

Since its introduction more than 50 years ago, hematopoietic stem-cell transplantation (HSCT) has transformed from an inescapably fatal procedure to one where cure from malignant and other nonmalignant hematologic diseases is becoming increasingly common. Nevertheless, longevity is not entirely restored. New causes of mortality have emerged; of particular importance is that of increased cardiovascular disease (CVD), related to metabolic syndrome and its components. Controversy exists over whether the metabolic abnormalities induced are a direct effect of HSCT itself or a consequence of other therapies involved...

BACKGROUND: The role of serum ferritin (SF) as a prognostic factor has been analyzed in patients with myelodysplastic syndromes (MDS) who have undergone hematopoietic stem cell transplantation (HSCT), but the prognostic role of elevated SF levels is still controversial in lower risk MDS patients. Therefore, we performed a meta-analysis of all available published literature to evaluate whether elevated SF levels are associated with a worse overall survival (OS) among patients with low risk MDS...

Mucopolysaccharidosis I-Hurler (MPS I-H) is the most severe form of a metabolic genetic disease caused by mutations of IDUA gene encoding the lysosomal α-L-iduronidase enzyme. MPS I-H is a rare, life-threatening disease, evolving in multisystem morbidity including progressive neurological disease, upper airway obstruction, skeletal deformity and cardiomyopathy. Allogeneic hematopoietic stem cell transplantation (HSCT) is currently the gold standard for the treatment of MPS I-H in patients diagnosed and treated before 2-2...

To investigate clinical characteristics and outcomes of transplantation in AML patients with FLT3-ITD/DNMT3A double mutation, we retrospectively analyzed 206 Chinese patients with AML after Sanger sequencing. Our analysis showed that AML patients with FLT3-ITD and DNMT3A R882 mutations had a higher white blood cell count and a lower complete remission (CR) rate after first induction chemotherapy. All 206 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) in status of CR. These results indicate that AML patients with FLT3-ITD and DNMT3A R882 double mutation show a higher 2-year cumulative incidence of relapse (CIR), lower 2-year overall survival (OS) rate, and lower 2-year leukocyte-free survival (LFS) after allo-HSCT...

Costs of HSCT in the United States have been widely reported, but complete information on costs in developing countries is lacking. We performed an analysis designed to assess the real, detailed costs of HSCT in Mexico. Using the database of the Current Accounts Department at our Institution, we performed a micro-costing based analysis of patients from 2010 through 2015 to obtain the overall cost of HSCT during the in-patient procedure and 2-month follow-up. One hundred five transplantations (57% autologous) were performed...

OBJECTIVE: Voriconazole as a triazole antifungal agent is widely used for prophylaxis or treatment of fungal infections in allogeneic hematopoietic stem cell transplantation (HSCT). It can increase blood concentrations of other medications including cyclosporine A (CsA) which are substrates for cytochrome P450 3A4. The aim of this study was to evaluate comparatively the interaction between oral/intravenous (IV) voriconazole and oral CsA. METHODS: Twenty-nine recipients of allogeneic HSCT who had been already on a steady dose of CsA and were started on oral or IV voriconazole were evaluated in a prospective cohort study...

Hematopoietic stem cell transplantation (HSCT) offers a cure for cancers that are refractory to chemotherapy and radiation. Most HSCT recipients develop chronic graft-versus-host disease (cGVHD), a systemic alloimmune attack on host organs. Diagnosis is based on clinical signs and symptoms, as biopsies are risky. T cells are central to the biology of cGVHD. We found that a low Treg/CD4+ T effector memory (Tem) ratio in circulation, lymphoid, and target organs identified early and established mouse cGVHD. Using deuterated water labeling to measure multicompartment in vivo kinetics of these subsets, we show robust Tem and Treg proliferation in lymphoid and target organs, while Tregs undergo apoptosis in target organs...

Chronic graft-versus-host disease (cGvHD) remains a major complication of allogeneic stem cell transplantation requiring novel therapies. CD146 and CCR5 are expressed by activated T cells and associated with increased T cell migration capacity and Th17 polarization. We performed a multiparametric flow cytometry analysis in a cohort of 40 HSCT patients together with a cGvHD murine model to understand the role of CD146-expressing subsets. We observed an increased frequency of CD146+ CD4 T cells in the 20 patients with active cGvHD with enhanced RORγt expression...

Severe aGvHD is a life-threatening complication after allogeneic HSCT. The GI tract is considered to play a key role in aGvHD, where the disease process can start and is one of the major target organs. Here, we present a case of a one-year-old child with a life-threatening GI-aGvHD stage IV, post-HSCT, resistant to steroids and MMF for 4 weeks. He was successfully treated with placenta-derived DSC.
